如图1所示内外带齿的棘轮零件的成形,一般采用切削加工或挤压成形,但这些工艺方法在大批量生产中都存在一些问题。下面介绍一种适于大批量自动化生产的冷挤压成形新工艺,由于该工艺设备没有顶出装置,结构简单,工作稳定,解决了带有顶出装置的挤压设备易产生不定向偏心荷载问题,改善了模具受力状态。 As shown in Figure 1 inside and outside the formation of toothed ratchet parts, the general use of cutting or extrusion, but these processes have some problems in mass production. The following describes a suitable for high-volume automated production of cold extrusion forming a new process, as the process equipment is not ejection device, simple structure, stable work, to solve the extrusion device with ejection device is easy to produce non-directional eccentric load Problems, improved die stress state.
