Front we have done a lot of metal processing split the contents of the bending process, but it certainly is not enough, because the product variety in abad, forming structure type is strange, we also discusses and analyzes the day in the future, as a qualified mould design engineer, must be able to keep up with the trend, need to constantly learning, improve their ability.
Only in this way can have a better development in the industry, technology, there is no best only better, the author here even if the 'introduction'.
Actually, metal processing molding process or can have a lot of is subdivided, such as: convex hull process, Z fold, crimping process, stretching process, and so on.
This article, we will come together to talk about the concrete method of crimping process.
Metal processing products, you think of what type?
Author analyzed together with everybody: the first: the circle is the most complete molding metal processing volumes is round process or product, this separation process is suitable for the core structure, namely must have core to forming in the middle.
So, suitable for roll round larger products, benefit is a core cover, volume products are round after round.
The second: this kind of contrary to the first, this is suitable for small round, insert molding without core structure, finally through empty shoot, suitable for small roll round, or product is thick and Angle is not high product molding process split.
Third: roll round of a material, and a tangent arc excessive, lead to can not directly at the first metal processing technology to design a split.
Due to large circular arc, we can make more, circular arc segment format for molding.
Finally crimping without core, direct air film, product type is not particularly round after oh.
Fourth: one of the very common roll round structure, its characteristic is the product volume circle is small, and roll round to end.
The roll round structure, we can use push inserted knife process, or by more than the empty process, engineering mode is suitable for slotting tool, can save work step, and continuous mode suitable for empty, because the structure more simple, rough.
