我厂于一九六四年试制成功 JA88—200型肘杆式金属挤压机以来,至一九八一年底已累计生产一百七十三台。本机床主要用途为挤压铝质牙膏管,电池锌筒及铝质电容器外壳,十多年来用户反映尚属良好。本机床在生产过程中亦曾作某些改进,但由于改动不大,且不涉及参数,故效果不显著。为此设计改型产品 JB88—200型及 JC88—200型。现将两改型产品的主要改进处逐一介绍于下。 Since the successful trial production of the JA88-200 elbow-type metal extruder in 1964, our factory has produced a total of 173 sets by the end of 1981. The main purpose of this machine is extrusion aluminum toothpaste tube, battery zinc cylinder and aluminum capacitor shell, the user reflects more than 10 years is still good. The machine tool in the production process has also been made for some improvements, but due to little change, and does not involve parameters, so the effect is not significant. Designed for this modification products JB88-200 type and JC88-200 type. Now the two major improvements of the modified products introduced one by one below.
