Design key points of progressive die: kitchen accessories skateboard
1. Radius of rounded corner of progressive die
The radius of the concave corner of the progressive die should be consistent in all directions.Otherwise, when bending, the blank will slide and the product will be offset, which will affect the accuracy and size. In addition, when designing progressive die, the radius of bending rounded corner should be selected appropriately, and should not be too large or too small. If the radius of rounded corner is large, it will cause local deformation or thinning of the product and affect the quality and surface roughness of the product.
2. Prevent blank deflection during bending
When designing the mold, the following preventive measures should be taken to prevent the deviation of the blank in the bending process: the mold should be equipped with a spring pressure device, and the part should be in a state of elastic compression before bending the leather, and then bending.
3. Prevent deformation during bending
Ignition barrel manufacturers for multi-angle progressive mold design, strive to be multi intersection multi Angle bending is not at the same time, the bottom dead point of mold bending, should be designed as far as possible to have the effect of bending correction, mold structure design should be fully considered to eliminate the phenomenon of rebound.When designing the positioning device, necessary measures should be taken to press the blank as much as possible during bending.
