本发明涉及钢管压槽加工设备领域，尤其涉及一种钢管在线压槽设备。The invention relates to the field of steel pipe grooving processing equipment, in particular to an online steel pipe grooving equipment.
背景技术Background Art
卡箍式管道连接因具有装拆维修方便、性能可靠、隔振吸声、零污染等良好的性能和优点，被广泛应用在液体、气体输送管道的连接中。卡箍式连接管道端部沟槽加工时，管壁放置在一对配合的凹辊和凸辊之间，通过凹辊转动和凸辊的缓慢进给加工沟槽。目前，沟槽加工采用人工上料、加工一端、管件掉头、加工另一端、人工下料的方式，劳动强度大，加工效率低。Clamp-type pipe connections are widely used in the connection of liquid and gas pipelines due to their convenient installation and maintenance, reliable performance, vibration isolation and sound absorption, and zero pollution. When processing the grooves at the ends of the clamp-type connection pipes, the pipe wall is placed between a pair of matching concave and convex rollers, and the grooves are processed by the rotation of the concave rollers and the slow feeding of the convex rollers. At present, the groove processing adopts the method of manual loading, processing one end, turning the pipe fittings, processing the other end, and manual unloading, which has high labor intensity and low processing efficiency.
而目前所用的管道端部压槽设备一般为设置在生产线外，即离线式加工：从生产线上转运钢管至压槽设备处加工完毕后再转运回生产线上，造成加工运行效率的降低，无法提高生产效率，转运流程仓储需求和离线设备也造成生产场地的浪费。The pipe end grooving equipment currently used is generally set up outside the production line, that is, offline processing: the steel pipe is transferred from the production line to the grooving equipment for processing and then transferred back to the production line, resulting in a decrease in processing efficiency and failure to improve production efficiency. The storage requirements of the transfer process and offline equipment also cause a waste of production space.

具体实施方式DETAILED DESCRIPTION
以下结合附图对本发明进行详细描述：The present invention is described in detail below with reference to the accompanying drawings:
本实施例以一次可加工8根钢管的一端压槽的钢管在线压槽设备为例进行描述。This embodiment is described by taking an online steel pipe grooving device that can process grooves at one end of 8 steel pipes at a time as an example.
如图1、2、3、4、5、6所示的一种钢管在线压槽设备，至少包括：位于上下游两端连接生产线上下游的的用于钢管上下料的中转架1；在两个中转架1间可往复运行转运钢管的移动小车2；沿上下游方向依次设置在两个中转架1之间并呈左右分布的两个滚槽机组3，滚槽机组3底部设有垂直于上下游方向可动的行走装置31；平行间隔设置在移动小车2和滚槽机组3之间的滚槽支架4；上料装置、移动小车2、滚槽机组3、滚槽支架4上设有相互作用的位置传感器，位置传感器可以为红外、激光测距、编码器、磁刷位移传感器（优选用磁刷位移传感器进行位置变化量的精确检测，其他的传感器用于辅助）等具有位置和距离检测能力的传感器的一种或多种组合，这些位置传感器共同接入具有控制功能的微机并为微机控制压槽工作的进行和精确控制提供参数，下述本设备的工作过程中的运行位置都由这些位置传感器检测并实现控制。（为实现钢管的两端承托，本实施例中的各个托架、支架等都为沿上下游方向对称成对设置）。An online grooving device for steel pipes as shown in Figures 1, 2, 3, 4, 5, and 6 comprises at least: a transfer frame 1 for loading and unloading steel pipes, which is located at both ends of the upstream and downstream and connects the upstream and downstream of the production line; a mobile trolley 2 for reciprocating the transfer of steel pipes between the two transfer frames 1; two groove rolling units 3 arranged in sequence between the two transfer frames 1 in the upstream and downstream directions and distributed left and right, and a movable walking device 31 perpendicular to the upstream and downstream directions is provided at the bottom of the groove rolling unit 3; a groove rolling bracket 4 arranged in parallel and spaced between the mobile trolley 2 and the groove rolling unit 3; interactive position sensors are provided on the loading device, the mobile trolley 2, the groove rolling unit 3, and the groove rolling bracket 4, and the position sensor can be one or more combinations of sensors with position and distance detection capabilities such as infrared, laser ranging, encoder, magnetic brush displacement sensor (preferably, a magnetic brush displacement sensor is used to accurately detect the position change, and other sensors are used for assistance), these position sensors are connected to a microcomputer with a control function and provide parameters for the microcomputer to control the progress and precise control of the grooving work, and the running positions in the working process of the following equipment are detected and controlled by these position sensors. (In order to support both ends of the steel pipe, the various brackets, supports, etc. in this embodiment are symmetrically arranged in pairs along the upstream and downstream directions).
本实施例中，移动小车2包括伺服电机驱动下的齿轮齿条形式进行行走的框体结构的行走支架21（齿条固定在地面作为轨道，行走支架21上安装伺服电机带动的齿轮行走）、可升降连接于行走支架21上方的升降支架22，本实施例中的升降支架22为类似于汽车用千斤顶的X型升降支架，其通过位于侧面的螺纹机构或液压机构实现支架的升降。以及设于升降支架22上方的多个等距间隔设置的第一托架23，第一托架23在本实施例中为塑料或其他相对软质的高强度材料制成的具有V槽的板件，相对软质的结构使得钢管在由中转架1转运到其上时相互冲击损伤减小，并消除可能的跳动导致钢管歪斜、掉落等问题，其V槽用于限位钢管并通过V槽结构的特性实现自定心保证后续压槽加工的位置精确性。第一托架23在升降支架22上也呈现沿上下游方向的左右对称以实现对于钢管两端的稳定承托输送。In this embodiment, the mobile vehicle 2 includes a frame structure of a rack and pinion structure driven by a servo motor to move (the rack is fixed on the ground as a track, and the servo motor is installed on the walking bracket 21 to move), a lifting bracket 22 connected to the upper part of the walking bracket 21, and the lifting bracket 22 in this embodiment is an X-shaped lifting bracket similar to a car jack, which realizes the lifting of the bracket through a threaded mechanism or a hydraulic mechanism located on the side. And a plurality of first brackets 23 arranged at equal intervals above the lifting bracket 22, in this embodiment, the first bracket 23 is a plate with a V groove made of plastic or other relatively soft high-strength materials. The relatively soft structure reduces the mutual impact damage of the steel pipe when it is transferred from the transfer rack 1 to it, and eliminates the possible problems of the steel pipe being skewed or falling due to the jumping. The V groove is used to limit the steel pipe and realizes self-centering through the characteristics of the V groove structure to ensure the position accuracy of the subsequent grooving process. The first bracket 23 also presents left-right symmetry along the upstream and downstream directions on the lifting bracket 22 to achieve stable support and transportation for both ends of the steel pipe.
本实施例中，滚槽支架4包括固定的底座41、通过伺服缸/伺服油缸实现大承载高精度的可升降连接于底座41的托台42和多个等距间隔设于托台42顶部的第二托架43，托台42使得其上的第二托架43同步实现升降以提高运行精确性。In this embodiment, the rolling groove bracket 4 includes a fixed base 41, a support platform 42 connected to the base 41 and capable of being raised and lowered by a servo cylinder/servo oil cylinder to achieve large load-bearing capacity and high precision, and a plurality of second brackets 43 equidistantly arranged on the top of the support platform 42. The support platform 42 enables the second brackets 43 thereon to be raised and lowered synchronously to improve the operating accuracy.
本实施例中，第二托架43包括框架结构的V型架431、通过销轴连接可转安装于V型架431的框架上的至少四个滚轮432（V型的每一边至少两个），滚轮432表面存在有防滑层，防滑层可以为套装在滚轮432表面的橡胶或其他软质层或通过滚花等方式加工在滚轮432表面的花纹，从而用于提高与钢管之间的摩擦力，防止其在加工过程中轴向受力滑脱。滚轮432用于保证钢管在转动压槽过程中的周向转动的流畅性。In this embodiment, the second bracket 43 includes a V-shaped frame 431 of a frame structure, and at least four rollers 432 (at least two on each side of the V-shaped frame) rotatably mounted on the frame of the V-shaped frame 431 through a pin connection. The surface of the roller 432 has an anti-skid layer, which can be a rubber or other soft layer sleeved on the surface of the roller 432 or a pattern processed on the surface of the roller 432 by knurling or other methods, so as to increase the friction between the steel pipe and prevent it from slipping under axial force during processing. The roller 432 is used to ensure the smoothness of the circumferential rotation of the steel pipe during the rotating groove pressing process.
本实施例中，V型架431通过气缸、油缸或直线电机调节装置433可调连接于托台42顶部，调节装置433的调节方向垂直于上下游方向。从而一方面可以通过移动调整位置实现对于不同长度钢管的支撑适应；另一方面可以对于其举升的钢管的位置进行微调以更好地适配滚槽机组3加工钢管。In this embodiment, the V-shaped frame 431 is adjustably connected to the top of the support platform 42 through a cylinder, oil cylinder or linear motor adjustment device 433, and the adjustment direction of the adjustment device 433 is perpendicular to the upstream and downstream directions. Therefore, on the one hand, the support adaptation for steel pipes of different lengths can be achieved by moving and adjusting the position; on the other hand, the position of the lifted steel pipe can be finely adjusted to better adapt to the processing of the steel pipe by the groove rolling unit 3.
本实施例中，滚槽机组3还包括安装在行走装置31上的壳体，行走装置31为伺服缸/伺服油缸和导轨组合形成的壳体的驱动和导向装置，壳体上安装有多个水平间隔设置的连接有驱动电机的动力头32和设于动力头32侧面意义对应的通过油缸驱动的滚槽头33，动力头32外轮廓为可张紧安装于钢管内壁的圆柱体，在圆柱体基础上，可以将其设置为气压/液压带动自动实现张紧的三爪卡盘、弹性膨胀柱等结构保证其插入钢管内部后可以实现张紧。动力头32内壁与驱动电机的输出轴耦合实现转动，其外部张紧安装在钢管内壁后即可将驱动电机的输出扭矩传递至钢管使其转动，同时油缸驱动滚槽头33压制钢管表面即压出凹槽，钢管的转动使得该凹槽相应回转形成需要的压槽。工作动力头32的直径可以根据钢管的实际内径进行更换，滚槽头33的截面形状、与钢管端部的间距可以根据设计的压槽形状参数通过安装位置调节和更换头部进行调整。In this embodiment, the groove rolling unit 3 also includes a housing mounted on a walking device 31. The walking device 31 is a driving and guiding device of the housing formed by a combination of a servo cylinder/servo oil cylinder and a guide rail. The housing is equipped with a plurality of horizontally spaced power heads 32 connected to a driving motor and a groove rolling head 33 driven by an oil cylinder and arranged on the side of the power head 32. The outer contour of the power head 32 is a cylinder that can be tensioned and installed on the inner wall of the steel pipe. On the basis of the cylinder, it can be set to a three-jaw chuck driven by air pressure/hydraulic pressure to automatically achieve tension, an elastic expansion column and other structures to ensure that it can achieve tension after being inserted into the steel pipe. The inner wall of the power head 32 is coupled with the output shaft of the driving motor to achieve rotation. After its outer surface is tensioned and installed on the inner wall of the steel pipe, the output torque of the driving motor can be transmitted to the steel pipe to make it rotate. At the same time, the oil cylinder drives the groove rolling head 33 to press the surface of the steel pipe, that is, to press out a groove. The rotation of the steel pipe causes the groove to rotate accordingly to form the required groove. The diameter of the working power head 32 can be replaced according to the actual inner diameter of the steel pipe, and the cross-sectional shape of the groove rolling head 33 and the distance from the end of the steel pipe can be adjusted by adjusting the installation position and replacing the head according to the designed groove shape parameters.
本实施例中，动力头32表面加工有防滑滚花以保证其张紧安装在钢管内壁后可以提供足够的摩擦力将钢管带动转动。In this embodiment, the surface of the power head 32 is processed with anti-skid knurling to ensure that it can provide sufficient friction to drive the steel pipe to rotate after being tensioned and installed on the inner wall of the steel pipe.
本实施例中，第一托架23数量等于两个滚槽机组3的动力头32数量。因为本实施例中一次进行8根钢管的一端压槽动作，故本实施例中的第一托架23数量为左右对称的每侧16个；每一个滚槽机组3具有8个于第一托架23等间隔的动力头32；滚槽支架4具有沿上下游方向对称的两组（稳定承托钢管），每组为沿上下游方向线性布置的两个以实现钢管两端的分别压槽加工进而进一步提高加工效率，每个滚槽支架4上的第二托架43也具有8个且分布分隔与第一托架23之间的间隔相等，同时第二托架43在垂直于上下游方向上与滚槽机组3的动力头32共线从而提供准确的压槽工序中的承托。In this embodiment, the number of first brackets 23 is equal to the number of power heads 32 of two groove rolling units 3. Because the groove pressing action of one end of 8 steel pipes is performed at a time in this embodiment, the number of first brackets 23 in this embodiment is 16 on each side, which is symmetrical; each groove rolling unit 3 has 8 power heads 32 equally spaced from the first bracket 23; the groove rolling bracket 4 has two groups symmetrically along the upstream and downstream directions (stable support of steel pipes), and each group is two linearly arranged along the upstream and downstream directions to realize the groove pressing processing of the two ends of the steel pipe respectively, thereby further improving the processing efficiency. The second brackets 43 on each groove rolling bracket 4 also have 8 and the distribution intervals are equal to the intervals between the first brackets 23. At the same time, the second brackets 43 are collinear with the power heads 32 of the groove rolling unit 3 in the vertical direction to provide accurate support in the groove pressing process.
本实施例中，中转架1上设有在平行于上下游方向的竖直平面内呈环形链节转动的第三托架11，多个第三托架11呈链节连接的形式成环，每个第三托架11上都有V槽来限位带动钢管。这一环形链在电机的驱动下转动，通过其V槽将上游生产线或移动小车2上的钢管带走并向移动小车2或下游生产线输送。移动小车2的升降支架22在完全收起时高度低于承载有钢管的第三托架11的高度，从而可以进入中转架1下方并通过抬升等方式进行钢管的转运。In this embodiment, the transfer rack 1 is provided with a third bracket 11 that rotates in a ring-shaped chain link in a vertical plane parallel to the upstream and downstream directions. Multiple third brackets 11 are connected in a ring in the form of chain links, and each third bracket 11 has a V-groove to limit and drive the steel pipe. This ring chain rotates under the drive of the motor, and takes away the steel pipe on the upstream production line or the mobile trolley 2 through its V-groove and transports it to the mobile trolley 2 or the downstream production line. When the lifting bracket 22 of the mobile trolley 2 is fully retracted, the height is lower than the height of the third bracket 11 carrying the steel pipe, so that it can enter under the transfer rack 1 and transfer the steel pipe by lifting and other means.
本实施例中，位于上游端的中转架1上游设有龙门架结构的方钢管焊接/螺接成型的储料架5，储料架5包括固定支架51和插接在固定支架51上可通过电动或手动在固定支架51上沿上下游方向伸缩移动的活动支架52，活动支架52上设有第四托架53。第四托架53为从活动支架52靠近中转架2一端凸起的用于限位钢管限位结构，固定支架51用于暂时储存并以单层平铺的方式存放上游生产线通过辊筒或输送带送入的钢管，从而便于位于上游端的中转架1转运钢管，在上游产量较大时既可以伸缩拉出活动支架52以提高其对钢管的储存能力以实现在生产线上的动态适应。同时整体储料架呈向下游侧的下斜，使得钢管在重力作用下紧密排布并且在前侧钢管运走后会自动补位。In this embodiment, a storage rack 5 formed by welding/screwing square steel pipes of a gantry structure is provided upstream of the transfer rack 1 at the upstream end. The storage rack 5 includes a fixed bracket 51 and a movable bracket 52 plugged into the fixed bracket 51 and capable of being telescopically moved on the fixed bracket 51 in the upstream and downstream directions by electric or manual means. A fourth bracket 53 is provided on the movable bracket 52. The fourth bracket 53 is a steel pipe limiting structure protruding from one end of the movable bracket 52 close to the transfer rack 2 and used to limit the position of the steel pipe. The fixed bracket 51 is used to temporarily store and store the steel pipes fed into the upstream production line through rollers or conveyor belts in a single-layer flat manner, so as to facilitate the transfer of steel pipes by the transfer rack 1 at the upstream end. When the upstream output is large, the movable bracket 52 can be telescopically pulled out to increase its storage capacity for steel pipes to achieve dynamic adaptation on the production line. At the same time, the overall storage rack is inclined downward toward the downstream side, so that the steel pipes are closely arranged under the action of gravity and automatically fill in the position after the front steel pipes are transported away.
本设备的工作流程如下：The working process of this equipment is as follows:
（1）上游生产线或储料架5向位于上游端的中转架1输送待加工的钢管，移动小车2移动至上游端并从中转架1上转运得到钢管。其中小车2转运得到钢管的动作为：中转架1上的第三托架11从上游生产线上转运得到8根钢管并链式移动至8根钢管水平间隔分布，移动小车2的升降支架22升起使得第一托架上23将第三托架11上的钢管托起获得钢管，这一方式可以一次转运高效地得到8根钢管，在运行时优先选用移动小车靠下游侧的8个第一托架23承托转运，此后移动小车2向下游移动至上游侧的8个第一托架23可以升起转运，此时可以设置靠上游侧的滚槽机组3与此时下游侧的8个第一托架23对应从而实现一端转运另一端即在加工的复合的工序以进一步提高工作效率。中转架1从储料架5或上游生产线转运钢管的动作如下：第三托架11在该中转架1的上游端略高于储料架5或上游生产线进料处的高度，在第三托架11向下游链式转动时，储料架5或上游生产线上的钢管即会被托起并向下输送，尤其是储料架5提供的钢管的单层排列结构，使得每一根钢管被运走后下一根即会滚落补位方便下一个第三托架11转运实现高效的自动化运行。(1) The upstream production line or the storage rack 5 delivers the steel pipes to be processed to the transfer rack 1 located at the upstream end, and the mobile trolley 2 moves to the upstream end and transfers the steel pipes from the transfer rack 1. The action of the trolley 2 to transfer the steel pipes is as follows: the third bracket 11 on the transfer rack 1 transfers 8 steel pipes from the upstream production line and moves in a chain manner to 8 steel pipes horizontally spaced, and the lifting bracket 22 of the mobile trolley 2 is lifted so that the first bracket 23 lifts the steel pipe on the third bracket 11 to obtain the steel pipe. This method can efficiently obtain 8 steel pipes in one transfer. During operation, the 8 first brackets 23 on the downstream side of the mobile trolley are preferentially used for support and transfer. After that, the mobile trolley 2 moves downstream to the 8 first brackets 23 on the upstream side and can be lifted for transfer. At this time, the groove rolling unit 3 on the upstream side can be set to correspond to the 8 first brackets 23 on the downstream side, thereby realizing a composite process of transferring at one end and processing at the other end to further improve work efficiency. The action of the transfer rack 1 transferring the steel pipes from the storage rack 5 or the upstream production line is as follows: the third bracket 11 is slightly higher than the height of the feeding point of the storage rack 5 or the upstream production line at the upstream end of the transfer rack 1, and when the third bracket 11 rotates downstream in a chain manner, the steel pipes on the storage rack 5 or the upstream production line will be lifted up and transported downward, especially the single-layer arrangement structure of the steel pipes provided by the storage rack 5, so that after each steel pipe is transported away, the next one will roll down to fill the position, which is convenient for the next transfer by the third bracket 11 to achieve efficient automatic operation.
（2）移动小车2运行至靠下游侧的8个第一托架与靠上游侧的滚槽支架4和滚槽机组3对齐，滚槽支架4的托台42抬升至高于第一托架23高度并使得钢管从第一托架23转运到第二托架43上，此后在位置传感器的作用下，移动小车2的升降支架22下降（防止干涉），托台42调整高度至钢管的轴线与动力头32的轴线重合。(2) The mobile trolley 2 moves to the point where the eight first brackets on the downstream side are aligned with the groove rolling bracket 4 and the groove rolling unit 3 on the upstream side. The support platform 42 of the groove rolling bracket 4 is lifted to a height higher than the first bracket 23 and the steel pipe is transferred from the first bracket 23 to the second bracket 43. Thereafter, under the action of the position sensor, the lifting bracket 22 of the mobile trolley 2 is lowered (to prevent interference), and the support platform 42 is adjusted to a height until the axis of the steel pipe coincides with the axis of the power head 32.
（3）行走装置31带动滚槽机组3向钢管处移动，托台42上的调节装置433也配合移动，直至动力头32插入钢管端部内并实现张紧，在动力头32插入的同时靠近滚槽机组3一侧的滚槽支架4下降，即使得形成远离滚槽机组3一侧的滚槽支架4和动力头32对钢管进行两端支撑的结构，减少此后压槽动作钢管的摩擦、提高压槽效率，并减少可能引起轴线偏移的支点数量。(3) The walking device 31 drives the grooving machine unit 3 to move toward the steel pipe, and the adjusting device 433 on the support platform 42 also moves in coordination until the power head 32 is inserted into the end of the steel pipe and tensioning is achieved. When the power head 32 is inserted, the grooving bracket 4 close to the side of the grooving machine unit 3 descends, so that a structure is formed in which the grooving bracket 4 and the power head 32 on the side away from the grooving machine unit 3 support the steel pipe at both ends, thereby reducing the friction of the steel pipe during the subsequent grooving operation, improving the grooving efficiency, and reducing the number of fulcrums that may cause axis deviation.
（4）张紧钢管的动力头32转动，滚槽头33受驱动下压在钢管端部压出环形的压槽。(4) The power head 32 for tensioning the steel pipe rotates, and the groove rolling head 33 is driven downward to press out an annular groove at the end of the steel pipe.
（5）压槽完成后靠近滚槽机组3一侧的滚槽支架4上升回复支撑，动力头32解除张紧并通过行走装置31回退至初始位置，两侧的滚槽支架4同步下降且移动小车2的升降支架22上升使得钢管回到由第一托架23承托。(5) After the groove pressing is completed, the groove rolling bracket 4 close to the groove rolling unit 3 rises and returns to the support, the power head 32 is released from tension and returns to the initial position through the walking device 31, the groove rolling brackets 4 on both sides are synchronously lowered and the lifting bracket 22 of the mobile trolley 2 rises so that the steel pipe returns to being supported by the first bracket 23.
（6）移动小车2移动至一端加工完成的钢管的另一端与下游侧的滚槽机组3对应，并重复步骤（2）-（5）中的工序实现另一端的压槽完成，同时，因为本实施例中的设置，移动小车2上游侧8个第一托架23承托的钢管也可以实现其第一个端部的压槽加工，进一步提高效率。(6) The mobile carriage 2 moves to the other end of the steel pipe with one end processed so as to correspond to the grooving machine unit 3 on the downstream side, and repeats the processes in steps (2) to (5) to complete the grooving on the other end. At the same time, due to the arrangement in this embodiment, the steel pipe supported by the eight first brackets 23 on the upstream side of the mobile carriage 2 can also be grooved at its first end, thereby further improving efficiency.
（7）两端加工完毕后的钢管由移动小车2举升至高于位于下游端的中转架1处，此后升降支架22下降将钢管转运到该中转架1上的第三托架11上，第三托架11此后向下游方向转动使得其上的钢管从其末端落下至下游生产线向检测、包装工段运输。(7) After the processing at both ends, the steel pipe is lifted by the mobile trolley 2 to a position higher than the transfer rack 1 located at the downstream end. Then, the lifting bracket 22 descends to transfer the steel pipe to the third bracket 11 on the transfer rack 1. The third bracket 11 then rotates in the downstream direction so that the steel pipe on it falls from its end to the downstream production line for transportation to the inspection and packaging section.
