Therefore, the application provides a cut anti-torsion support material structure and stamping die, can avoid the product to directly hit and turn round, the collision is hindered, guarantees product stability.

As shown in fig. 1 to 5, the slitting and torsionproof stock structure of the present embodiment is applied to a press die composed of an upper die 1 and a lower die 2, and includes an upper punch 11 and a lower punch 21 that can be combined with each other to jointly cut a product 4 from a material web 3.

In specific implementation, the product 4 is a stamping part formed on the material belt 3 in advance, and usually, a plurality of products 4 are formed on the material belt 3 at the same time, so that the number of the upper punches 11 can be set to be the same as that of the products 4, so that all the products 4 on the material belt 3 can be cut off at one time, and correspondingly, the lower punches 21 can be flexibly arranged in the form of inserts only by arranging cutting edges at positions tangential to the upper punches 11.

Alternatively, the number of the upper punches 11 is two, symmetrically arranged on both sides of the upper die 1, the number of the lower punches 21 is one, and the upper punches 11 are arranged in the middle of the lower die 2, as shown in fig. 1, and are positioned on the left and right sides of the lower punches 21.
