前言履带节是大型拖拉机、推土机行走机构的磨损件,随着我国拖拉机生产和拥有量的增加,对履带节的需要量逐年增长.我厂在一九七○年进行了履带节成型辊锻工艺的试验,获得成功.七一年生产5万件,七二年生产15万件,目前年产量可达30万件. 几年来的生产实践证明:履带节辊锻工艺较之锤上模锻工艺,有很多优点. 1.生产效率高:锤上模锻工艺一般为班产600件,我厂辊锻流水线最高班产1300件,平均班产800件,而且潜力还很大. 2.工人劳动强度低:采用正向推杆送料,只需一人操作,且易于掌握.辊锻机无震动,劳动条件好.
Foreword Track section is a large tractors, bulldozers running gear wear parts, with the increase of production and ownership of tractors in China, the demand for track sections increased year by year I plant in 1970 forging section roll forming process Of the test, the success of the production of 50000 in July, production of 150,000 in 1972, the current annual output of up to 300,000. Years of production practice has proved that: track roller section forging process than the hammer on the forging process , There are many advantages. 1. High production efficiency: Hammer on-die forging process is generally produced 600 classes, I plant roll forging the highest class production 1300, the average production of 800 classes, and the potential is still great. Low strength: the use of positive putter feeding, only one person operation, and easy to grasp. Roll forging machine without vibration, good working conditions.
