一、前言我们因需要将某厂 SI——3气动微震压实造型机的压头改造成为多触头,并为进一步获得对弹簧多触头压实造型特性的认识,在我院铸造教研室工号试验机上做了一系列实验,从中看出弹簧多触头的突出特点。以下,将分述我们所做的实验及对 SI—3造型机压头的设计。二、对多触头压实造型特性的探讨1.回顾压实造型生产中,对于较复杂的模型采用平压头存在着紧实度不均匀的弊 I. Introduction Because we need to transform the pressure head of SI-3 pneumatic microseismic compacting machine of a factory into multi-contact head, and in order to further understand the characteristics of multi-contact spring compaction molding, Number of test machine to do a series of experiments, from which the outstanding features of the spring multi-contact. Below, we will describe the experiments we made and the design of the head of the SI-3 molding machine. Second, the multi-contact compaction molding characteristics of 1. Review compaction molding production, for more complex models using flat head there is the uneven degree of solidity of the disadvantages of uneven
