本发明属于轮胎翻新技术领域，具体涉及一种轮胎翻新用膨胀鼓装置及轮胎翻新方法。The invention belongs to the technical field of tire retreading, and in particular relates to an expansion drum device for tire retreading and a tire retreading method.
背景技术Background technique
废旧轮胎翻修再利用是轮胎资源循环利用的主要途径，也是废旧轮胎减量的主要措施。轮胎翻新就是将被磨去和破损的部分经特殊工艺处理，换上新的橡胶结合体，使破损轮胎称为一条完整的轮胎。但在翻新过程中存在着一系列的问题，比如：与卡盘接触的轮胎胎口直径和外卡盘的直径并不完全相等，另外即使都是轿车轮胎，其不同厂家生产的不同品牌轮胎也会有差别，从而造成安装时胎口和卡盘有间隙，使得轮胎的圆心和卡盘的圆心偏心。打磨之后的轮胎不是圆心，而是椭圆形，会使轮胎快速非正常磨损，损坏车轴轴承、甚至造成爆胎影响安全。The refurbishment and reuse of waste tires is the main way to recycle tire resources, and it is also the main measure to reduce waste tires. Tire retreading is to replace the worn and damaged part with a new rubber combination, so that the damaged tire is called a complete tire. However, there are a series of problems in the retreading process, such as: the diameter of the bead of the tire in contact with the chuck is not exactly equal to the diameter of the outer chuck, and even if they are all car tires, different brands of tires produced by different manufacturers are also different. There will be a difference, which will cause a gap between the tire mouth and the chuck during installation, making the center of the tire and the center of the chuck eccentric. The tire after grinding is not the center of a circle, but an ellipse, which will cause rapid and abnormal wear of the tire, damage the axle bearing, and even cause a blowout to affect safety.
为了解决现有技术存在的问题，人们提出了各种各样的解决方案。例如，中国专利文献公开了一种胎面贴合机的定型装置及其方法[申请号：CN200810138001.7]，本发明在成型鼓向外涨开的过程中对扇形块施加向心的约束和复位力以避免出现扇形块错位和锁死问题，解决了成型鼓整体拆卸和更换问题，提高了内部结构之间的气力传送，但结构比较复杂，通过压缩气体来使膨胀鼓向外涨开，需要保证良好的密封性。In order to solve the problems existing in the prior art, various solutions have been proposed. For example, the Chinese patent literature discloses a shaping device and method of a tread laminating machine [Application No.: CN200810138001.7]. The invention imposes centripetal constraints and The reset force avoids the dislocation and locking of the sector blocks, solves the problem of overall disassembly and replacement of the forming drum, and improves the pneumatic transmission between the internal structures, but the structure is relatively complicated, and the expansion drum is expanded outwards by compressing the gas. Good sealing is required.

具体实施方式detailed description
下面结合附图说明本发明的具体实施方式：The specific embodiment of the present invention is described below in conjunction with accompanying drawing:
如图1所示，一种轮胎翻新用膨胀鼓装置，包括气缸1，主轴2，左盘3，右法兰盘4，锥度轴5，径向轴6，扩张板7，铁皮圈8，橡胶套9，卡环10，充气密封环11。左盘3内部安装有锥度轴5，锥度轴5与主轴2相连。径向轴6有八个(数量可根据左盘3与右法兰盘4大小确定)，均匀分布在右法兰盘4开的槽内，径向轴6上链接有扩张板7，径向轴6下端为一斜面，与锥度轴5的锥面相接处。左盘3与右法兰盘4通过螺栓连接，卡环10在主轴2的前端，气缸1通过卡环10拉动锥度轴5进行轴向运动，进而实现径向轴6的径向运动，实现膨胀鼓的膨胀功能。铁皮圈8分段包在扩张板7上，铁皮圈8外部包有橡胶套9。当主轴2前伸，由橡胶套9本身收缩力将扩张板7与径向轴6组成的整体压回原位，从而使锥度轴5移回到原位。这样就实现了膨胀鼓的收缩功能。As shown in Figure 1, an expansion drum device for tire retreading includes a cylinder 1, a main shaft 2, a left disc 3, a right flange 4, a taper shaft 5, a radial shaft 6, an expansion plate 7, an iron ring 8, rubber Set 9, snap ring 10, inflatable sealing ring 11. A taper shaft 5 is installed inside the left disk 3, and the taper shaft 5 is connected with the main shaft 2. There are eight radial shafts 6 (the number can be determined according to the size of the left disc 3 and the right flange 4), which are evenly distributed in the grooves of the right flange 4, and the radial shaft 6 is connected with an expansion plate 7, radial The lower end of the shaft 6 is an inclined surface, which is connected with the tapered surface of the tapered shaft 5 . The left disc 3 and the right flange 4 are connected by bolts. The snap ring 10 is at the front end of the main shaft 2. The cylinder 1 pulls the tapered shaft 5 through the snap ring 10 to move axially, and then realizes the radial movement of the radial shaft 6 to realize expansion. The expansion function of the drum. The iron ring 8 is wrapped on the expansion plate 7 in sections, and the outside of the iron ring 8 is covered with a rubber sleeve 9 . When the main shaft 2 stretches forward, the contraction force of the rubber sleeve 9 itself will press the expansion plate 7 and the radial shaft 6 back to its original position, so that the taper shaft 5 will move back to its original position. In this way, the contraction function of the expansion drum is realized.
气路布置如图1、2、3、4、5所示，在右法兰盘4右端链接有充气密封环11，保证膨胀鼓转动时，充气排气管装置固定不动。充气密封环11上开有三个孔，201、203为通孔，分别外接进气管和出气管。202为螺纹孔，不打通，将充气密封环11通过螺栓连接至固定装置上，起到固定充气密封环11的作用，防止其转动。进气管、出气管通过通孔201、203进入槽205中，槽204、206中安装有橡胶密封环207，防止漏气。右法兰盘4上的通气孔301和通气孔306分别连接气管401和气管402，两根气管分别接到扩张板7的三通403上。三通403与扩张板7上的孔501紧密相连，扩张板7上开有通气孔404，与孔501相通。这样就使得气体从孔501进入通气孔404，实现了轮胎充气的功能。由于充气密封环11的固定，右法兰盘4转动，不会导致总气管转动引起事故，而气管401、气管402可以随着膨胀鼓的转动而转动，不会引起缠绕。当完成打磨或贴胶后，排气。放气时，气体可以沿原路返回，实际操作过程中，主轴2前伸，橡胶套9收缩，膨胀鼓缩小，气体就由轮胎与橡胶套的大间隙中跑掉，实现轮胎放气。1, 2, 3, 4, and 5 shown in the air circuit layout, an inflatable sealing ring 11 is connected to the right end of the right flange plate 4 to ensure that the inflatable exhaust pipe device is fixed when the expansion drum rotates. There are three holes on the inflatable sealing ring 11, and 201 and 203 are through holes, which are externally connected to the air inlet pipe and the air outlet pipe respectively. 202 is a threaded hole, which is not opened, and the inflatable sealing ring 11 is connected to the fixing device by bolts to play the role of fixing the inflatable sealing ring 11 and prevent it from rotating. The air intake pipe and the air outlet pipe enter the groove 205 through the through holes 201, 203, and rubber sealing rings 207 are installed in the grooves 204, 206 to prevent air leakage. The ventilation hole 301 and the ventilation hole 306 on the right flange 4 are connected to the air pipe 401 and the air pipe 402 respectively, and the two air pipes are respectively connected to the tee 403 of the expansion plate 7 . The tee 403 is closely connected with the hole 501 on the expansion plate 7 , and the expansion plate 7 is provided with a ventilation hole 404 communicating with the hole 501 . In this way, the gas enters the vent hole 404 from the hole 501, realizing the function of tire inflation. Due to the fixing of the inflatable sealing ring 11, the rotation of the right flange 4 will not cause accidents caused by the rotation of the main trachea, and the trachea 401 and the trachea 402 can rotate with the rotation of the expansion drum without causing entanglement. When finished sanding or gluing, vent the air. When deflating, the gas can return along the original path. In the actual operation process, the main shaft 2 is stretched forward, the rubber sleeve 9 shrinks, the expansion drum shrinks, and the gas just runs away from the large gap between the tire and the rubber sleeve to realize tire deflation.
如图1、6所示，本发明还提供一种轮胎翻新方法，将轮胎602放置于扩张板7上，用扩张板的边沿凸起部601限定轮胎602的子口；在气缸1的驱动作用下，主轴2前端的卡环10拉动锥度轴5进行轴向运动，通过锥度轴5的左右运动驱动径向轴6的上下运动，从而促使径向轴6末端的扩张板7从内向外涨开，使之能够适合不同胎径的轮胎；待轮胎602的圆心与左盘3和右法兰盘4的圆心重合后，再通过充气孔、通气孔和气管向轮胎602充气以将轮胎602撑起；膨胀鼓装置和轮胎602在电机的驱动下一起转动，对胎面进行打磨和贴胶处理；轮胎602打磨和贴胶结束后，关闭进气阀，橡胶套9本身的收缩力将扩张板7与径向轴6组成整体压回原位，从而使锥度轴5移到原位，将轮胎602从膨胀鼓装置上卸下。As shown in Fig. 1, 6, the present invention also provides a kind of tire retreading method, tire 602 is placed on the expansion plate 7, limits the slit of tire 602 with the edge protrusion 601 of expansion plate; Next, the snap ring 10 at the front end of the main shaft 2 pulls the tapered shaft 5 to move axially, and the left and right motion of the tapered shaft 5 drives the radial shaft 6 to move up and down, thereby prompting the expansion plate 7 at the end of the radial shaft 6 to expand from inside to outside , so that it can be suitable for tires with different tire diameters; after the center of circle of the tire 602 coincides with the center of circle of the left plate 3 and the right flange plate 4, inflate the tire 602 through the air hole, air hole and air tube to prop up the tire 602 The expansion drum device and the tire 602 rotate together under the drive of the motor, and the tread is polished and glued; after the tire 602 is polished and glued, the air intake valve is closed, and the contraction force of the rubber sleeve 9 itself will expand the plate 7 It is integrally formed with the radial shaft 6 and pressed back to its original position, so that the tapered shaft 5 is moved to its original position, and the tire 602 is unloaded from the expansion drum device.
