摘要
针对大同煤矿集团公司中央机厂近年来工作阻力大于10 000 k N或支护高度大于4 m液压支架的大批量制造,在生产过程中,从结构件的原材料选用、下料要求、组点成型、焊接、机加工、表面抛丸除锈、以及结构件的涂装工艺要求等各个工序制定并严格执行制造工艺规范,达到了预期效果。
In view of mass production of hydraulic support that working resistance is greater than 10 000 kN or support height is more than 4 m in our factory in recent years, in the production process, from the every processe of material selection of mechanism part, blanking requirement, grouping point and molding, surface shot derusting, coating process of mechanism part and so on, manufacturing process specification is formulated and strictly implemented, it achieves the desired purpose.
