摘　　要：在某型号销合链弯链板自动化冲压级进模的研发中,由于冲孔工序涉及废料难以去除和工件不便取出的问题,使得该型号销合链弯链板的加工难以实现自动化。针对此问题,延续弯链板自动化冲压级进模的设计思路,提出一种双斜楔横向对冲冲孔模具设计方案,用于代替原有的悬架式竖直冲孔模具,并运用DEFORM-3D软件对横向对冲冲孔工艺方案进行仿真验证。在此基础上,开展冲裁间隙、凸凹模刃口尺寸和冲裁力等工艺参数计算,并对斜楔、冲孔装置、凹模、压料装置和顶料装置等关键零部件展开结构设计,运用SOLIDWORKS软件完成模具的三维设计。最后,研制模具样机并开展冲压试验验证。结果表明,所研制的双斜楔横向对冲冲孔模具能够较好地应用于弯链板自动化冲压级进模中。经抽样检测,冲孔加工后的工件全部合格,同时也有效地解决了冲孔废料难以去除和工件不便取出的问题,实现了弯链板的自动化生产,有效缩短了模具的研发时间与试模周期。In the development of an automatic stamping progressive die for a certain type of curved chain plate of pin-joint chain, it is difficult to automate the processing of curved chain plate of pin-joint chain because the punching process involves the problem that the scrap is difficult to remove and the workpiece is inconvenient to take out. Therefore, for this problem, the design idea of automatic stamping progressive die for curved chain plate was continued, and a double-slanting wedge horizontal hedging punching die design scheme was proposed to replace the original hanging vertical punching die, and the horizontal hedging punching process scheme was simulated and verified by software DEFORM-3D. Furthermore, on this basis, the process parameters such as punching gap, die or punch edge dimensions and punching force were calculated, and the structure design of key components such as slanting wedge, punching device, die, pressing device and discharging device was carried out, and the 3D design of die was completed by software SOLIDWORKS. Finally, the prototype die was developed and the stamping test was carried out for verification. The results show that the developed double-slanting wedge horizontal hedging punching die can be well applied to the automatic stamping progressive die for curved chain plate. After sampling inspection, all the workpieces after punching are qualified, which also effectively solves the problems that it′s difficult to remove the punching scrap and inconvenient to take out the workpieces. Thus, the automatic production of curved chain plate is realized, and the development time of die and die trial period are effectively shortened.
