Description
[technical field]
The utility model relates to a kind of hardware stamping mould, and particularly a kind of progressive die scrap (bridge) stamping-out does not have the hardware stamping mould structure of burr.
[background technology]
In pressed part, sharp burr often appears in the plane of disruption of five metals mould stamping-out part, and operating personnel can touch sharp burr in process of production unavoidably, very easily cause the injury to operating personnel, and security incident takes place.In addition, hardware equally also can touch sharp burr unavoidably when being assembled into product, and the injury that exists operating personnel causes security incident.On the other hand, the part hardware is installed in the middle of the electric equipment products, and the burr on the hardware very likely can drop on electronic component, may cause fault, and severe patient possibly cause integrated circuit to open circuit and burn out equipment.Along with manufacturing development of five metals and pursuit, accurate day by day to the requirement of hardware, particularly to strict especially on the security performance of hardware products, the portioned product designer can require hardware that burr can not be arranged.Therefore, the mould design is removed aspect the burr at corresponding hardware, and the face that appends is given as security operation and removed burr; It is no problem that this technology is removed burr for the single operation, yet adopts the single operation mode of production, and production efficiency is low; And need with great amount of manpower resource and device resource; Cause cost high, the production safety to operating personnel does not ensure simultaneously, has a big risk.And progressive die production can be enhanced productivity greatly, and simultaneously unnecessary great amount of manpower resource and production equipment can reduce production costs, and security has certain guarantee, can reduce the production safety risk greatly.But continuous mould connects the scrap (bridge) local location of product removes very difficulty of burr because scrap (bridge) be always joining work pieces to the end operation just can thrust, the product burr after thrusting can not be removed burr in this mould.The insider once repaid examination at the lower mould plate with precompressed line punching press C angle, after technology such as cut off and remove burr, but effect is all undesirable, need remove burr or increase stamping procedure and remove burr through appending the worker usually, just can reach requirement of products.
[utility model content]
The purpose of the utility model is to overcome deficiency of the prior art, provides a kind of simple in structure and practical progressive die scrap (bridge) stamping-out not have the burr structure.
The technical scheme of the utility model is achieved in that it comprises the first work step stamping-out structure and the second work step stamping-out structure; The said first work step stamping-out structure is the scrap (bridge) stamping-out preshearing structure that makes progress, and the said second work step stamping-out structure is that the scrap (bridge) stamping-out is cut off structure downwards;
