一、前言铜衬是各种机械中常见的一种零件,它与箱体或外壳的配合大都为过渡配合或轻静配合,过去装配时通常由钳工师傅用铁锤敲入或压力和压进,但这二种办法都较容易碰坏铜衬,在过盈量较大时还会使铜衬的外园表面拉手,严重影响装配质量,再加上由于这种工艺手段导致装配不均匀性,往往在铜衬压装后会产生一些不规则的收缩变形,必须重新进行括削,费时费工.本文着重叙述了简便易行的干冰冷装铜衬新工艺.
I. Introduction Copper lining is a kind of common parts in all kinds of machinery. It cooperates with the box or the shell mostly for the transition fit or the quiet fit. In the past, the fitter often used a hammer to input or press and press , But these two methods are more likely to damage the copper lining, the larger the amount of interference will make the lining of the copper lining of the outer handle, seriously affecting the quality of the assembly, coupled with this process as a result of uneven assembly , Often in the copper liner after pressing will have some irregular shrinkage, you must re-cut, time-consuming work.This article focuses on the simple and easy dry ice-mounted copper liner new technology.
