经铁道部批准,我厂从西德BMD公司引进一台AME170·140型空气冲击造型机,计划今年安装完。该机重点用于牵引电机座(铸钢件)的生产。这种造型机的基本原理,特点是什么呢?现作一简单介绍。随着我国电力机车生产的发展,铸造生产多年来全靠手工造型已经不能满足需要。近年来,我厂铸造新厂房里添制两台Z2520型造型机,将解决中小件的生产。但我厂铸钢件的关键产品牵引电机座为大型铸件,重约二吨,结构复杂,厚薄不均匀,要求高,数量多,用现有的Z520不能生产,为此,经过一年半的调研、招标,最后确定引进一台空气冲击造型机。
With the approval of the Ministry of Railways, our factory imported an AME170 · 140 air impact molding machine from West Germany BMD Company and plans to install this year. This machine is mainly used for traction motor seat (cast steel) production. The basic principle of this machine, what is the characteristic? Now make a brief introduction. With the development of electric locomotive production in our country, the casting production can not meet the need by hand for many years. In recent years, I plant two new factory casting Z2520-type molding machine, will solve the production of small and medium-sized pieces. However, the key products of our steel castings traction motor seat for large castings, weighing about two tons, the structure is complex, uneven thickness, high demand, the number of large, with the existing Z520 can not produce, for which after a year and a half Research, bidding, and finally determine the introduction of an air impact molding machine.
