Abstract
本发明提供一种薄头螺栓冷镦切边磨具，包括上模和下模，上模包括上模套和上切边模，上切边模嵌设于上模套的下端；下模包括下模套，下模套内从下至上依次设置有支撑垫块和下切边模，支撑垫块和下模套之间嵌设有主垫块，支撑垫块内部设有顶料杆和T型垫块，下切边模内部设置有推管，T型垫块的上端和推管对准，T型垫块的下端设置有用于限制T型块下移位置的限位台；推管的中心设置有管芯，管芯与顶料杆连接；其中，上模位于下模的上方，推管内部设有用于容纳螺栓的容纳腔，容纳腔内从上至下具有外倒角、薄头孔、内倒角。与现有技术相比，本方案中的磨具在使用时能够快速、精准的对薄头螺栓进行冷镦切边处理，且切边平整、精度高、成品率较高。
