Strictly control the shape and size of the stamping parts:
First, the requirements of the bending parts:
1, the shape of the bending part should be symmetrical, the bending radius should not be less than the minimum allowable bending radius of the material.
2, bending with holes, in order to avoid deformation of the hole
3, the curved side is too short not easy to shape, it should make the curved side of the straight part of the H>2 delta. If the H is very short, the need to set aside an appropriate margin to increase H, then increased to a curved metal.
Two, the requirements of drawing parts:
1, drawing parts should be simple, symmetrical shape, the depth should not be too large. In order to make the least number of drawing, easy forming.
2, drawing parts of the radius of the process is not increased in the case. Otherwise, it will increase the number of deep drawing and plastic work, but also increase the number of molds, and easy to produce waste and improve the cost.punching a good pre-made with a punch punch mold for processing, mainly for sheet metal processing, that is, most of the material processing sheet, the processing efficiency is relatively high for mass production. The process is divided into engineering and continuous mode, the mold is also called a single die, and some more complex parts to use several sets of mold; and continuous mold cavity in the mold product shape split several parts in a Mold, so punch a trip is a finished product. High-speed continuous punch can process three or four hundred products per minute.
