钣金加工下料环节所涉及的生产工艺

2018-07-04 16:04:07 常州亿创钣金加工厂 阅读

钣金加工是一种特殊的加工工艺,它的特殊性不仅是在它的作业对象上,还包括了它的相关操作中。因为钣金加工通常都是针对金属薄板进行的,而且包括了剪、冲、切、复合、折、焊接、铆接、拼接、成型等多项复杂的工序。虽然它与一般的切割加工有共同之处,但很明显要求要高很多,那什么样的设备完成这一特别的加工工艺呢?

单从钣金加工的下料这一环节来看,可采用的方式就有很多,一种是冲床切割下料,就是利用冲床将零件展开后的平板结构冲压成型。这种方式最大的特点就是直接高效,并且能够实现成本的减少,用在批量生产中尤为合适。

另一种下料方式是NC数控切割下料,先将工艺编写成数控程序,然后让其根据这些程序将工件冲出来。由于操作比较简单,因此这类加工方式是目前使用最为广泛的数控切割加工,而考虑到加工材料的厚度因素,所以以数控等离子切割居多。

最后还不能忘了激光切割下料,就是利用激光切割方式,在整块板材上将其工件的结构形状切割出来,以便于后续作业的需要。

Sheet metal processing is a special processing technology. Its particularity is not only in its object of operation, but also in its related operations. Because the sheet metal processing is usually aimed at the metal sheet, it also includes a number of complicated processes, such as shearing, punching, cutting, compound, folding, welding, riveting, splicing, forming and so on. Although it has something in common with the general cutting process, it obviously requires a lot of equipment. What kind of equipment can complete this special processing technology?

From the point of sheet metal processing, there are many ways that can be used, one is the blanking of the punching machine, which is the stamping forming of the plate structure after the expansion of the parts. The biggest feature of this method is direct efficiency, and can reduce costs, especially in batch production.

Another way of cutting material is NC NC cutting and cutting. First, the process is programmed into NC programs, and then the workpiece is washed out according to these procedures. Because of the simple operation, this kind of processing method is the most widely used numerical control cutting process at present, but taking into account the thickness of the processing material, the numerical control plasma cutting is the most.

In the end, we can not forget the laser cutting, which is the use of laser cutting, cutting the structure and shape of the workpiece on the whole plate, so as to facilitate the follow-up work.
