一、前言四柱万能液压机是我厂主要产品之一.适用于可塑性材料的压制工艺,如弯曲、翻边、拉伸等,也可从事于校正、压装、砂轮成形、冷挤金属零件成形或其他成形工艺. 我厂生产的四柱万能液压机从50吨至300吨共五种规格.经过不断地革新改进和反复地实践与提高,试制成功了新的四柱万能液压机系列.结构、性能以及参数作了全面的改进.其中100吨和315吨经过鉴定,反映较好,在主机重量方面以100吨为例,原重量为5.5吨,改进后为2.7吨.图1及图2为新旧产品的外观图.
I. INTRODUCTION Four-column universal hydraulic press is one of the main products of our factory.It is suitable for the pressing process of plastic materials, such as bending, burring, stretching, etc. It can also be used in the calibration, press-fitting, wheel forming, cold extrusion metal parts forming or Other Forming Process: The four-column universal hydraulic press produced by our factory has five specifications from 50 tons to 300 tons.After the innovation and improvement and repeated practice and improvement, the trial success of the new series of four-column universal hydraulic press.The structure, performance and parameters Of which 100 tons and 315 tons were identified, reflecting the better, in the host weight to 100 tons, for example, the original weight of 5.5 tons, improved to 2.7 tons Figure 1 and Figure 2 for the appearance of old and new products Figure
