一、钢丝缠绕机架简介大型锻压机械中的液压机机架,通常是做成三梁四柱式,它的尺寸和重量都较大.随着压力吨位的增大,这种结构愈显得笨重,不仅耗费钢材,而且给制造、安装和运输带来了不少困难.在使用过程中,机架的某些部位,容易产生应力集中,形成了强度的薄弱环节,常常引起疲劳破坏.因此,寻求合理结构形式的机架是当前压机发展的趋向之一. 我国工人阶级遵照毛主席“中国人民有志气,有能力、一定要在不远的将来,赶上和超过世界先进水平”的教导,发扬自力更生的革命精神,在较短的时间内,已在一种新型结构型式的压机机架——高强度钢丝缠绕机架的研制方面做出了成绩. 这种新型机架的基本原理是:考虑到整体式机架在较大工负荷下,会破裂成数块.既然如此,我们可以事先就将机架做成合理的分块式(见图1),外面包缠以有预张力的高??度钢丝.这 First, the wire winding rack Introduction Large forging machine hydraulic machine frame, usually made of three beams and four columns, its size and weight are larger.With the increase of the pressure tonnage, the more this structure appears cumbersome, not only Consuming steel, but also to create, install and transport a lot of difficulties in the use of some parts of the rack, prone to stress concentration, the formation of the strength of the weak links, often lead to fatigue damage.Therefore, to seek reasonable The structure of the rack is one of the trends of the current press development.Chinese working class follows the teachings of Chairman Mao, “Chinese people have ambition, ability, must catch up with and surpass advanced world level” in the near future, carry forward Self-reliance Revolutionary spirit, in a relatively short period of time, has been made in the development of a new type of structural press frame - high-strength steel wire winding rack The basic principle of this new rack is: Taking into account the overall rack under heavy load in a large, will be broken into several pieces, so that we can make a reasonable frame before the block (Figure 1), wrapped around the pre-tension high Degree of wire
