钣金加工中,在下料和焊接这两个工序中,我们应具体知晓其哪些知识要点呢,从而来很好了解这两个方面?这也是大家所关心和想要知道的,因此下面,就针对上述这一问题。

钣金加工中,在下料这一工序中,其方式有很多,但总的来讲,其常见的有:

剪床:就是使用剪床来下料,其精度是比较低的,因此只能进行条料和快料的加工,但只能是无孔无切角的。

冲床:就是利用冲床来进行下料,可以冲裁成各种形状,因此它是可以用于大批量生产中的,但是缺点是要设计好模具才行。

NC数控下料:就是通过数控方式来下料,不过要先编写好程序才能够进行,其加工精度也不高。

镭射下料:就是通过激光切割方式来进行下料,可以切割成各种复杂形状的,但是成本比较高。

钣金加工中的焊接,其种类,则一般有三种,为熔化焊、压力焊及钎焊这三种。

In sheet metal processing, in the two processes of blanking and welding, what knowledge points should we know specifically, so as to get a good understanding of these two aspects? This is what we all care about and want to know.

In sheet metal processing, there are many ways in the process of cutting, but generally speaking, there are:

Shears: that is, the use of shearing machine to cut material, its accuracy is relatively low, so it can only be processed strip and quick processing, but it can only be without holes and corner.

Punching machine: it is the use of the punching machine to carry out the blanking, can be blanked into a variety of shapes, so it can be used in large mass production, but the disadvantage is to design a good mold.

NC NC blanking is to cut material by numerical control, but it is necessary to write a good program before it can be processed, and its machining accuracy is not high.

Laser blanking: cutting through laser cutting can cut into various complex shapes, but the cost is relatively high.

There are three kinds of welding in sheet metal processing. They are three kinds of fusion welding, pressure welding and brazing.
