Description

A kind of pad blanking die

Technical field

This utility model relates to a kind of mould structure for processing pad, refers in particular to a kind of compound cutting die that can blanking and punching two procedures be simultaneously processed.

Background technology

Accompanying drawing 1 show pad, and this part is typical chevron, workpiece shapes, relatively simple for structure, and symmetrical, it is common that produce in enormous quantities. This part mainly has Blanking Shaping and bending twice manufacturing procedure, wherein Blanking Shaping operation is generally adopted twice processing of simple mode division at present, punching after first blanking, need two molds, production efficiency is relatively low, and owing to being point two procedures problem that is easily caused that machining accuracy is low, it is difficult to meet part production demand. Therefore, it is necessary to design a kind of compound cutting die blanking and punching can processed simultaneously.

Utility model content

This utility model is in order that overcome the deficiencies in the prior art and propose a kind of compound cutting die that can blanking and punching two procedures be processed simultaneously.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of pad blanking die, including male model, master mold and guidance set; Described master mold includes die shoe, recessed model fixing seat, die, stripper, discharging elastic component; Described male model includes die shank, upper bolster, upper padding plate, convex model fixing seat, piercing punch, trimming punch, back pieces block, back pieces elastic component; Described upper bolster is connected by screw and die shank are fixing; It is connected by guidance set between described upper bolster and die shoe; Described guidance set includes guide pin bushing and guide pillar; Described recessed model fixing seat is fixedly connected on die shoe by securing member; Described die is fixed on the middle part of recessed model fixing seat; Described die periphery is arranged with stripper; The lower end of described stripper is fixedly connected with discharging elastic component; Upper padding plate, convex model fixing seat, trimming punch are fixedly connected sequentially from top to bottom by described upper bolster by securing member; Described piercing punch is fixedly connected on convex model fixing seat; Described back pieces block is set in the periphery of piercing punch, and is positioned at inside trimming punch; The upper end of described back pieces block is fixedly connected with back pieces elastic component.

Preferably, described guidance set is removable accurate slip guide pillar.

Preferably, described guidance set has two groups, is arranged on rear side.

Preferably, the upper surface of described recessed model fixing seat is provided with pin stop.

Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that

Pad blanking die of the present utility model, adopt upside_down mounting compound die, punched scrap can pass through die and spill from workbench hole, workpiece is by after on punch band above, released by back pieces block, billot is deviate from by the stripper on die shoe, this easy to operate and safety, can guarantee that higher production efficiency.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is gasket construction schematic diagram to be processed;

Accompanying drawing 2 is pad stamping-out mode structure schematic diagram of the present utility model;

Accompanying drawing 3 is pad blanking die top view of the present utility model.

Wherein: 1, die shoe; 2, recessed model fixing seat; 3, die; 4, stripper; 5, discharging elastic component; 6, die shank; 7, upper bolster; 8, upper padding plate; 9, upper padding plate; 10, piercing punch; 11, trimming punch; 12, back pieces block; 13, back pieces elastic component; 14 guide pin bushings; 15, guide pillar.

Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Pad stamping-out mode structure of the present utility model as shown in Figure 1, including male model, master mold and guidance set; Described master mold includes die shoe 1, recessed model fixing seat 2, die 3, stripper 4, discharging elastic component 5; Described male model includes die shank 6, upper bolster 7, upper padding plate 8, convex model fixing seat 9, piercing punch 10, trimming punch 11, back pieces block 12, back pieces elastic component 13; Described upper bolster 7 is connected by screw is fixing with die shank 6; It is connected by guidance set between described upper bolster 6 and die shoe 1; Described guidance set includes guide pin bushing 14 and guide pillar 15; Described recessed model fixing seat 2 is fixedly connected on die shoe 1 by securing member; Described die 3 is fixed on the middle part of recessed model fixing seat 2; Described die 3 periphery is arranged with stripper 4; The lower end of described stripper 4 is fixedly connected with discharging elastic component 5; Upper padding plate 8, convex model fixing seat 9, trimming punch 11 are fixedly connected sequentially from top to bottom by described upper bolster 7 by securing member; Described piercing punch 10 is fixedly connected on convex model fixing seat 9; Described back pieces block 12 is set in the periphery of piercing punch 10, and is positioned at inside trimming punch 11; The upper end of described back pieces block 12 is fixedly connected with back pieces elastic component 13.
