  • 简介:随着我国经济的快速发展,锻造行业已进入工业发展的高速期,并越来越显示出其桥梁与基础的重要作用。近几年,随着锻造工业的迅速发展,各种先进的锻压设备、锻造工艺迅速得到普及应用,使我国锻造工业迎来一个质的飞跃。但是,锻造行业还存在一个关键问题没得到有效解决,并影响和制约着锻造工业的高速发展,那就是环保问题。锻造环境污染问题的源头就是锻造常用的石墨系列脱模剂,其污染程度众所周知,可谓万恶之源。

  • 简介:洛阳市冠华精齿轮总厂(以下简称“冠华”)是生产汽车农用车及拖拉机用差速器直齿锥齿轮的专业厂家.已有十多年建厂历史。建厂之初,精齿轮因具有节能、节材、结实耐用而逐渐代替传统的切削齿轮,但随着精齿轮行业生产厂家的不断增多.特别是近两年南方个体私营企业涉足精齿轮领域,采取无序的价格竞争.使得精齿轮行业的利润跌入低谷.有些农机齿轮仅是维持成本.几乎无利润可言。

  • 简介:的使用前面我们已经讲到过在钣金加工过程中.冲孔、拉伸时对材料施加的应力可以在被加工材料的屈服强度以下.与其相比,锻压加工的压缩力如果达不到被加工材料屈服强度的3-5倍,就不能使材料充填到模具内腔的边边角角。
