Bending process analysis:

A: The bending and bending machine is formed by bending and bending, and its advantages are as follows:

1. The molding rebound is small,

2. The product is better

3. Mold costs are less

B: Stamping, the disadvantages are:

1. The forming rebound is large,

2. The product is poor in one degree, and the product is greatly affected by the hardness.

3. More mold costs

Its advantages are:

1, stamping equipment is cheaper

2, high production efficiency

 

Description:

* The springback is small, the mold radius is 95-97% of the forming radius.The springback of each point is controllable and evenly distributed, which is very effective for multiple radii; it doesn't depends on experience.

* Automatic generate the radius template - By input CAD drawing or manually input radius (multi-radius, single radius is not a problem), solve the problem of relying on experience.

* Only one motor, automatic oil distribution by servo control, 24 hours production, temperature rise 55 degrees, and no noise; energy saving, environmental protection, solve the problem of heating system from hydraulic system.

* Solve the problem that radius gradually becomes larger or inconsistent after releasing single radius material.

For example, 180 degree stretch forming: Before: need over 190 degrees, released then forming by springback, and end radius is not the same with middle radius. Now: just bend to 181 degrees, springback is small and consistent, and end radius is same as middle radius.
