一种适用于液压套筒冷挤压成型模具

Cold extrusion forming die suitable for hydraulic sleeve

Abstract

本发明提供了一种适用于液压套筒冷挤压成型模具,包括上模板和下模板,下模板上设有压板,压板中部设有冲头,上模板的下部设有与其一体的凹模,凹模中设有与工件形状匹配的压槽,上模板的上部还设有模柄,上模板、凹模、模柄中贯穿设置连接动力输出端上的顶压工件的打料杆。本模具的设计,使得对液压套筒采用冷挤成型得以实现。工作效率显著提高,制造成本大幅降低。其结构简单,易于实现。
The invention provides a cold extrusion forming die suitable for a hydraulic sleeve. The die comprises an upper die plate and a lower die plate, wherein a pressing plate is arranged on the lower die plate; a punch is arranged in the middle of the pressing plate; a female die integrated with the upper die plate is arranged on the lower part of the upper die plate; a pressing groove of which the shape is matched with that of a workpiece is formed in the female die; a die handle is arranged on the upper part of the upper die plate; and a striking rod which is connected to a power output end and used for pressing the workpiece penetrates through the upper die plate, the female die and the die handle. By the die, the hydraulic sleeve can be subjected to cold extrusion forming; working efficiency is obviously improved, and manufacturing cost is greatly reduced; and the die has a simple structure and is easy to implement.
