铜套磨损后,可以用压缩的方法修理,使其内径缩小,外径增大,达到重新使用的目的。有许多柴油机的连杆铜套是有外油槽的,为了使外油槽在压缩后不变形,我们自制了一套胎具,专门用来压修带外油槽的铜套。现以压修4125型柴油机连杆铜套为例,说明如下。本胎具由上、下压胎(图1),铜套上、下胎(图2)、外油槽半圆胎(图3,车完后,从中间锯开)和中心轴(图4)组成。压缩前,先将磨损超限的铜套镗圆,消除磨损痕 After wear copper sleeve, you can use the compression method to repair, make it smaller diameter, diameter, to achieve the purpose of re-use. There are many diesel engine connecting rod copper sleeve is the outer groove, in order to make the outer groove is not deformed after compression, we made a set of car tires, designed to repair the copper sleeve with the outer groove. Is to repair the 4125 diesel engine connecting rod copper case, described below. The device consists of upper and lower pressure tire (Figure 1), copper sleeve, the next tire (Figure 2), the outer tank semicircle (Figure 3, after the car, sawing from the middle) and the central axis . Before compression, wear out the copper bushing round the first limit, to eliminate wear marks
