Description

A kind of mould structure for hitting side forming to death for stainless steel elastic slice

Technical field

The utility model relates to a kind of stamping dies, hit side forming to death for stainless steel elastic slice in particular to one kind Mould structure.

Background technique

In the part of production office (OA) product, a stainless steel elastic slice is encountered, is material as shown in Figure 1 to Figure 2 The stainless steel of 0.4MM, and be symmetrical member, hits side shape to death at S, rolls over this shape, and it is extra quality that product requirement hits side to death, extra quality heavy Folded part reaches entire product plane.It is 45 degree of folding according to general technology, rolls over 90 degree, roll over negative angle, in folding negative angle, hits side to death, altogether Divide 4 steps that could complete to hit the shape on side to death, since product is smaller, die space is also small, must use slide block structure just when rolling over negative angle It can complete.It is bulldozed or claps specifically, hitting side forming to death and being generally divided into, being bulldozed and pushing down product not for upper and lower mould is extra quality overlapping Part is come the forming of stack part using slipper push, and clapping is also intended to upper and lower mould and pushes down not stack part, by upper and lower mould Shaped portion hit to death product achieve the effect that fold it is extra quality.Due to being all to push down the part of not stack to prevent product in forming process In walk about, guarantee that product size precision and forming process are stablized, but this product reaches entire product plane due to extra quality, without extra face It overstocks tightly, conventional forming will necessarily make deformation of products walk material, can not be formed into and need shape.
