不锈钢冲压弯头的机械加工技术是怎样的?

2019-04-27 17:06:36

不锈钢冲压弯头经机械加工后的光洁表面的钝化性较好,铸造、喷砂等所得工件表面粗燥,不利于钝化。不锈钢冲压弯头的处理就是利用固态金属相变规律,采用加热、保温、冷却的方法,改善并控制金属所需组织与性能(物理、化学及力学性能等)的技术。而对于不锈钢冲压弯头的热处理无非就是达到要求的硬度或者抗拉强度或者抗屈服度等技术要求,正火,就是加热的处理,目前的正火处理包括电加热炉,燃煤加热或者是燃油加热,这也是较为常见的热处理方式,要求不是严格的不锈钢冲压弯头都是需要经过这道手续的,即使不锈钢冲压弯头是热成型的,但是正火所需要的温度和时间一般不是很长,要求达到客户压制的可塑性就可以了,但是为了全部达到原材料所原有的硬度等指标就需要再重新进行热处理。
