Process Arrangements of Bending Stamping
 Analysis how many procedures from the rough to the finished bending stamping when determine the manufacturing process of bending part.
The general principle in the bending stamping process is that work arrangements outer corner of the first bend after bend angles, bend after the second part does not affect the previous bending deformation and after the last bend to take the appropriate positioning curved base into account times.
Work arrangements of bending stamping as far as possible to meet the quality requirements of precision parts so that the number of bending stamping processes reduces, the mold structure is simple, easy operation, high output, low rejection rate.
The general method of arranging processes for bending stamping is:
1. To the simple pieces of bending stamping with curved shape, such as the V-shaped, U-shaped, Z-shaped and other parts, you can use a bent shape.
2. To the curved pieces of bending stamping with complex shape, it normally takes shape with double or multiple bend.
3. The bending stamping with symmetrical bending. The geometry of the work piece itself with one side of the bend in the development of technology programs, they should be bent in pairs, and then cut.
4. Add connection with bending stamping. When the curved edge of the work piece with its gap, the gap is also out with such a direct, inevitable Crossings phenomenon can not be serious shape, in such cases, connections in the bending stamping must be added together with the gap until after bending, and then removed the excess part of the gap.
5. For the volume, size smaller curved pieces of bending stamping, to increase the productivity, more processes can cut off the continuous process of blanking bent shape.
