我厂生产的上海-120推土机,其履带板原用45钢,由于耐磨性差,易变形,影响产品质量。后改用40Mn 2Si,但断料困难,用锯床下料,一根锯条只能锯一块料,浪费大,速度慢。用压力机冲裁,需要几百吨的冲床,我厂无此设备,因此用气割下料,后来搞成了这台半自动履带板切割机,较手工气割,效率提高三倍,切割口表面光滑,质量提高。现介绍如下: I plant the Shanghai -120 bulldozers, the original 45 of its track shoes, due to poor wear resistance, deformation, affecting product quality. After the switch to 40Mn 2Si, but the broken material is difficult to cut with a sawing machine, a saw blade can only saw a piece of material, waste large, slow. Punching with a press, you need hundreds of tons of punch, I did not plant this equipment, so gas cutting, and later became a semi-automatic crawler cutting machine, gas cutting more than three times the efficiency of the cutting surface smooth Quality improvement. Now introduced as follows:
