本发明涉及磨料水射流机械设备设计技术领域，尤其涉及一种基于前混合磨料射流切割曲面厚度不均匀板材的装置。The invention relates to the technical field of abrasive water jet mechanical equipment design, in particular to a device for cutting a plate with uneven thickness on a curved surface based on a pre-mixed abrasive jet.
背景技术Background technique
水射流是由喷嘴流出形成的不同形状的高速水流束，射流的流速取决于喷嘴出口截面前后的压力降。水射流是能量转变与应用的最简单的一种形式。通常，动力驱动泵通过对水完成一个吸、排过程，将一定量的水泵送到高压管路，使其以一定能量到达喷嘴。而喷嘴的孔径要求比高压管路直径小得多，因此到达喷嘴的这一一定量的水要想流出喷嘴孔，必须加速。这样，经过喷嘴孔加速凝聚的水就形成了射流。The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Water jetting is the simplest form of energy transformation and application. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water that accelerates condensation through the nozzle hole forms a jet.
然而，现有的前混合磨料射流切割设备虽然实现曲面厚度不均匀板材工件的切割加工功能，但存在加工精度低，射流能量浪费严重等问题，尤其前混合磨料射流设备因受磨料罐体积的限制，无法提供长时间持续作业，射流能量的浪费进一步缩短了切割作业时间。有些前混合磨料射流切割设备无法根据板材工件的弯曲率及厚度来实时调节喷枪的距离工件的靶距和移动速度，无法保证曲面厚度不均匀板材工件的切割质量，严重影响切割效率和工件加工质量，有些前混合磨料射流切割设备无法实现并联工作伺服控制同步运动，难以实现精确调节喷枪的射流参数功能，还有的前混合磨料射流切割设备难以实现自动设置射流切割参数功能，无法精确保证射流切割靶距参数，不能满足实际情况的需求。However, although the existing pre-mixed abrasive jet cutting equipment can realize the cutting and processing function of the plate workpiece with uneven thickness on the curved surface, there are problems such as low processing accuracy and serious waste of jet energy, especially the pre-mixed abrasive jet equipment is limited by the volume of the abrasive tank , unable to provide long-term continuous operation, the waste of jet energy further shortens the cutting operation time. Some pre-mixed abrasive jet cutting equipment cannot adjust the target distance and moving speed of the spray gun to the workpiece in real time according to the curvature and thickness of the plate workpiece, and cannot guarantee the cutting quality of the plate workpiece with uneven surface thickness, which seriously affects the cutting efficiency and workpiece processing quality , some pre-mixed abrasive jet cutting equipment cannot realize parallel working servo control synchronous movement, it is difficult to realize the function of accurately adjusting the jet parameters of the spray gun, and some front-mixed abrasive jet cutting equipment is difficult to realize the function of automatically setting jet cutting parameters, and cannot accurately guarantee jet cutting The target distance parameter cannot meet the needs of the actual situation.

现场使用时，首先，操作人员将曲面厚度不均匀板材工件固定在工件台上端的靶物架上，调节智能检测装置的位置使上检测器下端的球形头与下检测器上端的球形头位于曲面厚度不均匀板材工件的两侧，再调节起始喷头与曲面厚度不均匀板材工件位置，确保喷头底部与曲面厚度不均匀板材工件上侧面的距离处于合适切割的靶距范围内，设立曲面厚度不均匀板材工件起点位置后，根据数控面板上的走刀线路依次通过控制器将行走参数依次传输到辐射均布孔内的应力测试传感器上，辐射均布孔内的应力测试传感器根据路线自动分配依次激活辐射均布孔内对应的应力测试传感器。When using on-site, firstly, the operator fixes the sheet workpiece with uneven thickness on the curved surface on the target frame at the upper end of the workpiece table, and adjusts the position of the intelligent detection device so that the spherical head at the lower end of the upper detector and the spherical head at the upper end of the lower detector are located on the curved surface. On both sides of the plate workpiece with uneven thickness, adjust the position of the initial nozzle and the workpiece with uneven thickness on the curved surface to ensure that the distance between the bottom of the nozzle and the upper side of the workpiece with uneven thickness on the curved surface is within the appropriate cutting target distance. After the starting position of the sheet metal workpiece is uniform, the walking parameters are sequentially transmitted to the stress test sensors in the radiation uniform distribution holes through the controller according to the tool feed line on the NC panel, and the stress test sensors in the radiation uniform distribution holes are automatically assigned in sequence according to the route Activate the corresponding stress test sensor in the radiation distribution hole.

The spherical head 531 at the upper end of 42 is located on both sides of the sheet material workpiece 1 with uneven curved surface thickness, and then adjust the position of the initial nozzle 623 and the sheet material workpiece 1 with uneven curved surface thickness to ensure the distance between the bottom of the nozzle 623 and the upper side of the sheet material workpiece 1 with uneven curved surface thickness Within the range of target distance suitable for cutting, after setting up the starting position of workpiece 1 with uneven thickness on the curved surface, the travel parameters are sequentially transmitted to the stress test sensor 511 in the uniform radiation hole 5 through the controller according to the cutting line on the numerical control panel Above, the stress test sensors 511 in the radiation uniform distribution hole 5 sequentially activate the corresponding stress test sensors 511 in the radiation uniform distribution hole 5 according to the automatic allocation of routes.
其次，操作人员将混合腔7移动到实验室非工作区内，再混合腔7固定，将水管接入端安装在高压泵站73的水箱上，通过高压胶管将高压泵站73输出端与混合腔7的输入端相连接，再通过高压胶管将混合腔7的输出端与喷枪62的输入端相连接，启动高压泵站73使高压水进入磨料罐71内并在混合腔混合腔7内与磨料混合，磨料混合液经高压胶管和喷枪62从喷头623中喷出，使用过后的磨料混合液从切穿的缝隙经通孔421和C形同步架3的下侧壁上的长腰形孔34流入工件台22内。Secondly, the operator moves the mixing chamber 7 to the non-working area of the laboratory, then fixes the mixing chamber 7, installs the water pipe access end on the water tank of the high-pressure pump station 73, and connects the output end of the high-pressure pump station 73 to the mixing chamber through the high-pressure rubber hose. The input end of the chamber 7 is connected, and the output end of the mixing chamber 7 is connected with the input end of the spray gun 62 through a high-pressure rubber hose, and the high-pressure pump station 73 is started so that the high-pressure water enters the abrasive tank 71 and is mixed with the mixing chamber 7 in the mixing chamber. Abrasive mixing, the abrasive mixed liquid is ejected from the nozzle 623 through the high-pressure rubber hose and the spray gun 62, and the used abrasive mixed liquid passes through the through hole 421 and the long waist-shaped hole on the lower side wall of the C-shaped synchronous frame 3 from the gap cut through. 34 flows into the workpiece table 22.
再次，启动控制器，在走刀过程中，被激活的应力测试传感器511根据实际走刀的位置，来调节切割射流参数，根据反馈的切割射流参数进行切割作业，直至完成曲面厚度不均匀板材工件1全部走刀过程并完成切割作业。具体是：曲面厚度不均匀板材工件1两侧弯曲率和厚度检测的参数通过导柱53和弹簧52，并将位移参数经应力测试传感器511转换为力参数，应力测试传感器511通过数据线将参数传输给控制器21，控制器21通过数据线启动步进电机412，再步进电机412的驱动下，齿轮4111带动竖直齿条622使沿着喷枪孔6内进行上下移动并调节喷头623与曲面厚度不均匀板材工件1的靶距，与此同时，二维机床台2根据控制器21内参数调节C形同步架3 的位置，进行切割作业。 Again, start the controller, and during the cutting process, the activated stress test sensor 511 adjusts the cutting jet parameters according to the actual cutting position, and performs the cutting operation according to the fed-back cutting jet parameters until the sheet workpiece with uneven surface thickness is completed 1 Complete the cutting process and complete the cutting operation. Specifically: the parameters of curvature and thickness detection on both sides of the plate workpiece 1 with uneven thickness on the curved surface pass through the guide post 53 and the spring 52, and the displacement parameters are converted into force parameters through the stress test sensor 511, and the stress test sensor 511 passes the parameters through the data line. Transmission to the controller 21, the controller 21 starts the stepper motor 412 through the data line, and then driven by the stepper motor 412, the gear 4111 drives the vertical rack 622 to move up and down along the spray gun hole 6 and adjust the nozzle 623 and The target distance of the plate workpiece 1 with uneven thickness on the curved surface. At the same time, the two-dimensional machine tool table 2 adjusts the position of the C-shaped synchronous frame 3 according to the internal parameters of the controller 21 to perform cutting operations.
最后，操作人员依次关闭控制器21和磨料罐71下端的磨料阀门，待喷枪62内全部输出的为清水后，降低高压泵站73的输出流量，直至关闭高压泵站73，根据下次作业时间，合理清理磨料罐71内的磨料，做好设备定期维护，等待下次进行切割作业工作。Finally, the operator closes the controller 21 and the abrasive valve at the lower end of the abrasive tank 71 in turn, and after all the output in the spray gun 62 is clean water, the output flow of the high-pressure pump station 73 is reduced until the high-pressure pump station 73 is closed. , reasonably clean up the abrasive in the abrasive tank 71, do regular maintenance of the equipment, and wait for the next cutting operation.
