设备在装配和修理过程中,常常遇到螺栓或销子断(或锈死)于机体中的现象,这是装配或修理钳工大伤脑筋的事,下面介绍取出断螺栓或断销的方法,供大家参考。一、专用工具(见图所示)材料为T10A,三角及圆锥部分HRC5O～55;φ25体部及方部HRC40～45二、操作方法螺栓、销子断(或锈死)于机体内无法卸下时,利用钻孔配合上述自制工具进行处理。1。根据断螺栓、销子外径的大小用下列经验公式选择钻头:
Equipment in the assembly and repair process, often encountered bolt or pin broken (or rust) in the body phenomenon, which is fitting or repair fitter big headache, the following describes the removal of broken bolts or broken off the method, For reference. First, the special tools (see photo) Material T10A, triangular and conical parts HRC5O ~ 55; φ25 body and the Department of HRC40 ~ 45 Second, the operation Bolt, the pin off (or rust died) in the body can not be unloaded Under, the use of drilling with the homemade tools for processing. 1. According to the broken bolt, pin diameter size using the following empirical formula to select the drill bit:
