冲压连续模具在使用过程中，做好维护工作是非常有必要的，更需要进行认真耐心的维护工作，这样才能更加保证冲压连续模具的安全性和使用性。

In the process of using the stamping die, it is necessary to do the maintenance work well. It is more necessary to carry out the serious and patient maintenance work. In this way, the safety and the usability of the stamping die can be guaranteed.

下面进一步阐述冲压连续模具的维护事项。

The following is further elaborated on stamping maintenance of continuous mold.

1、凸凹模的维护

1. Maintenance of convex and concave die

凸凹模拆卸时，应留意模具原有的状况，以便后续装模时方便复原。有加垫或者移位的，要在零件上刻好垫片的厚度，并做好记录。更换凸模要试插脱料块凹模是否顺畅，并试插与凹模间隙是否均匀，更换凹模也要试插与冲头间隙是否均匀。针对修磨凸模后凸模变短，需要加垫垫片达到所需要的长度，应检查凸模有效长度是否足够。

When removing the convex and concave die, we should pay attention to the original condition of the mold, so that it can be restored easily after the mold is installed. If there are cushions or dislocations, the thickness of the gaskets should be engraved on the parts. To replace the punch, it is necessary to try to insert the stripper block, whether the die is smooth, and whether the gap between the test insert and the concave die is uniform. In order to shorten the back punch of the grinding punch, it is necessary to add gasket to reach the required length, and check whether the effective length of the punch is enough.

更换已断凸模要查明原因，同时要检查相对应的凹模是否有崩刃，是否需要研磨刃口。组装凸模，要检查凸模与固定块或固定板之间是否间隙足够，有压块的，要检查是否留有活动余量。组装凹模应水平置入，再用平铁块置入凹模面上，用铜棒将其轻敲到位，切不可斜置强力敲入，凹模底部要倒角。装好后要检查凹模面是否与模面相平。

The reason for changing the broken punch is to find out the reason. At the same time, we should check whether the corresponding die has the edge and whether the grinding edge is needed. To assemble the punch, check whether there is enough gap between the punch and the fixed block or the fixed plate. The concave die should be placed horizontally and placed on the die surface with the flat iron block. The copper bar should be struck in place. It must not be slanted and forced to strike. The bottom of the concave die should be chamfered. After loading, check whether the die face is level with the mold surface.

凸模凹模以及模芯组装完毕后，要对照料带做必要检查，各部位是否装错或装反，检查凹模和凹模垫块是否装反，落料孔是否堵塞，新换零件是否需要偷料，需要偷料的是否足够，模具需要锁紧部位是否锁紧。

After the die and die core are assembled, the necessary inspection should be made on the blanking belt, whether the parts are wrong or installed, check whether the die and the die are blocked, whether the blanking holes are blocked, whether the new parts need to be stolen, whether the material needs to be stolen, the die needs to be locked tightly.

注意做脱料板螺丝的锁紧确认。锁紧时，应从内至外，平衡用力交叉锁紧，不可先锁紧某一个螺丝再锁紧另一个螺丝，以免造成脱料板倾斜，导致凸模断裂或模具精度降低。

Pay attention to the locking confirmation of the stripper screw. When locking, the balance should be interlocked from inside to outside, and a screw should not be locked before locking another screw, so as to avoid the slant of the stripper and cause the punch break or the die precision to be reduced.

2、脱料板的维护

2, the maintenance of the stripper

脱料板的拆卸可先用两把起子平衡撬起，再用双手平衡使力取出。遇拆卸困难时，应检查模具内是否清理干净，锁紧螺丝是否全部拆卸，是否因卡料引起的模具损伤，查明原因再做相应处理，切不可盲目处置。

The removal of the stripper plate can be prized by balancing the two screwdrivers first, and then balance with the two hands to remove the force. When it is difficult to disassemble, it is necessary to check the cleanness of the mould, whether the locking screw is dismantled all, the damage of the mould caused by the card material, and find out the reasons for the corresponding treatment.

组装脱料板时，先将凸模和脱料板清理干净，在导柱和凸模导入处加润滑油，将其平稳放入，再用双手压到位，并反复几次。如太紧应查明原因（导柱和导套导向是否正常，各部位是否有损伤，新换凸模是否能顺利过脱料板、位置是否正确），再做相应处理。固定板有压块的，要检查脱料背板上让位是否足够。

When the stripper is assembled, the punch and the stripper are cleaned up first, and the lubricating oil is added to the guide and punch import place, which is placed smoothly, then pressed into position with both hands, and repeated several times. If it is too tight to find out the reasons (whether the guide and guide sleeve is normal, the parts are damaged, whether the new punch can go through the stripper and the position is correct), and then do the corresponding treatment. The fixed plate has a pressing block, and it is necessary to check whether the position on the stripper backboard is enough.

脱料板与凹模间的材料接触面，长时间冲压产生压痕，当压痕严重时，会影响材料的压制精度，造成产品尺寸异常不稳定等，需对脱料镶块和脱料板进行维修或重新研磨。等高套筒应作精度检查，当不等高时会导致脱料板倾斜，其精密导向平稳弹压功能将遭到破坏，须加以维护。

The material contact surface between the stripper and the die can produce the indentation for a long time. When the indentation is serious, it will affect the pressing precision of the material and cause the abnormal instability of the product size. It is necessary to repair or regrind the stripper and stripper. The contour sleeve should be inspected for accuracy. When the height is not equal, the stripper plate will be tilted, and its precision guided smooth press function will be destroyed and must be maintained.
