Abstract

The utility model discloses a die for punching and trimming a flexible-connection copper strip, which comprises an upper die plate and a lower die plate, wherein a male die is fixed on the upper die plate; a female die is fixed on the lower die plate; tool edge holes corresponding to the position of the male die are formed on the female die; a workpiece to be processed is arranged between the male die and the female die; the male die comprises a punching male die and a trimming male die; the tool edge holes comprise a punching tool edge hole and a trimming tool edge hole which correspond to each other; the punching male die and the punching tool edge hole are arranged in the positions corresponding to the pre-punching position of the workpiece to be processed; and the trimming male die and the trimming tool edge hole are arranged in the positions corresponding to the pre-trimming position of the workpiece to be processed. The die of the utility model is capable of completing the two procedures of punching and trimming at one punching step and preventing burrs from being formed at the trimmed side, thus effectively guaranteeing the processing quality of the products and improving the production efficiency of the flexible-connection copper strip.

Description

The mould that a kind of copper strips punching that is used to be flexible coupling is cut edge

Technical field

The utility model relates to a kind of metalwork processing mold, relates in particular to the mould that a kind of copper strips punching that is used to be flexible coupling is cut edge.

Background technology

As shown in Figure 1, the copper strips 6 of being flexible coupling is overlapping after welding makes for a plurality of Copper Foils, need carry out punching in the copper strips 6 corresponding pre-punched hole positions 61 that are flexible coupling after the welding processing, and, also need to handle by milling the limit operation because welding can form broken edge.When milling the limit operation, the fixing comparatively complicated and copper strips 6 that is flexible coupling of copper strips 6 of being flexible coupling is out of shape because milling the limit easily, mill on the end face 63 of the copper strips 6 that is flexible coupling behind the limit and form burr easily, the copper strips 6 that is flexible coupling needs to handle through deburring more just can carry out the silver-plated subsequent step of Denging.Therefore, the copper strips 6 that is flexible coupling will pass through punching at least after welding, mills limit and deburring and handles, and production efficiency of products is low and defect rate is higher.

Summary of the invention

The purpose of this utility model provides a kind ofly can finish the mould that the punching of the punching of the copper strips that is flexible coupling and edge treated is cut edge by a punching press.

For achieving the above object, mould of the present utility model comprises cope match-plate pattern and lower bolster, be fixed with punch on the cope match-plate pattern, be fixed with die on the lower bolster, die is provided with and corresponding edge of a knife hole, punch position, the cross sectional shape in edge of a knife hole is corresponding with the cross sectional shape and the size of punch with size, work piece is arranged between punch and the die, punch is driven by cope match-plate pattern and can move downward and the excess stock of stamping-out work piece enters the edge of a knife hole of die, described punch comprises piercing punch and side cut punch, described edge of a knife hole comprises corresponding punching edge of a knife hole and edge-trimming cutter oral pore, described piercing punch and punching edge of a knife hole are provided with the position corresponding to pre-punched hole position on the work piece, and described side cut punch and edge-trimming cutter oral pore are provided with the position corresponding to pre-side cut position on the work piece.

Adopt structure of the present utility model, in the process of a punching press, when piercing punch was finished punching on the pre-punched hole position of work piece, the side cut punch was finished the side cut operation with the pre-side cut position of work piece, has improved production efficiency of products effectively.In addition, for softer metals, with respect to milling the limit operation, the precision of stamping-out trimming technology is held easily, is difficult for forming burr, has removed the deburring step from, has guaranteed product quality when enhancing productivity.

Work piece of the present utility model is the copper strips that is flexible coupling, and the cross sectional shape of side cut punch and edge-trimming cutter oral pore is the U type, and the inward flange of U type is consistent with the edge shape that the copper strips that is flexible coupling forms behind stamping-out.Described side cut punch and edge-trimming cutter oral pore cooperatively interact and cut the copper strips that is flexible coupling, thereby form the edge that meets technological requirement on the copper strips that is flexible coupling.

The end face of side cut punch of the present utility model is provided with and can guides the side cut punch to cooperate the guide ledges that the copper strips that is flexible coupling is sheared with the edge-trimming cutter oral pore.Guide ledges protection side cut punch can not damage because of accident collision, and the side cut of guide ledges guiding simultaneously punch aligns the side cut position copper strips that is flexible coupling is cut edge.

In sum, mould of the present utility model can be finished punching and two operations of cutting edge in a punching course, and cut edge and be difficult for forming burr, compared with prior art, adopt mould of the present utility model in the crudy that guarantees product, improved the production efficiency of the copper strips that is flexible coupling simultaneously effectively.
