级进模的设计要点： Design points of progressive die for precision stamping parts :
精密冲压件 级进模的凹模圆角半径 1. Die fillet radius of progressive die for precision stamping parts
级进模的凹模圆角半径各方向要一直。 The corner radius of the die of the progressive die of the precision stamping part must be the same in all directions. Otherwise, when bending, the blank will slip, and the product will be offset. Please press the accuracy and size, and when designing the progressive die, the radius of the bending fillet should be selected appropriately. It should not be too large or too small. The angular radius is such that the product is locally deformed or thinned, which affects the quality and surface roughness of the product.
2. To prevent the deviation of the blank during the bending process
模具时，为了预防弯曲过程中的坯料的偏移，要采区如下预防措施：模具应设有弹压装置，记在皮料的弯曲前应有部分处于弹性压紧状态，然后在进行弯曲。 When designing a precision stamping die, in order to prevent the deviation of the blank during the bending process, the following precautions should be taken in the area: the die should be provided with a spring pressing device. Remember that before the bending of the leather, a part should be elastically compressed. Bend.
3. To prevent deformation during bending
多角级进模具设计时，力求是多交多角弯曲不同时进行，模具弯曲的下死点时，应尽量设计成有校正弯曲的效果，模具结构设计应充分考虑到回弹的现象。 For the design of the multi-angle progressive die for precision stamping parts , the multi-angle and multi-angle bending should not be performed at the same time. The bottom dead point of the die bending should be designed to have the effect of correcting the bending as much as possible. The mold structure design should fully consider the phenomenon of springback. . When designing the positioning device, it is necessary to take necessary measures as far as possible to make the workpiece press the blank as much as possible during the bending process.
