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.
