Abstract

The utility model discloses a side edge cutting mold of a round drawing piece, comprising an upper die part, a punch part and a lower die part, wherein the upper die part comprises an upper die seat, an upper pressing plate and a limiting column; the punch part comprises a side cutting punch, an upper pushing block and an outer fixed knife edge; the upper pushing block is fixedly connected with the upper die seat, the outer fixed knife edge is fixedly connected with a lower die supporting block, and two sides of the side cutting punch are provided with an upper knife edge clamping plate and a lower knife edge clamping plate; the lower die part comprises a lower die seat, an inner pressing block, a lower stripping plate and the lower die supporting block; the lower stripping plate is fixedly connected at the lower end of the inner pressing block; and the punch part is provided with eight side cutting punches which are uniformly distributed in a way of surrounding into a circle at 45-degree intervals, so that the production efficiency is improved and the service life of the mold is prolonged.

Description

Circular tensioning member side cutting die

Technical field

The utility model belongs to the mould class, is specifically related to a kind of circular tensioning member side cutting die.

Background technology

Cut edge in circular tensioning member bottom surface, be the common a kind of processing technology of sheet metal component that stretches, the process equipment that use in the prior art field is with the intact flanged workpiece of stretching, cuts edge with the special-purpose slotting machine of rotation, but there is following defective in it: cutting shoulder is irregular, and quality be cannot say for sure to demonstrate,prove; Production efficiency is low; The otch section life-span is short, fragile, production cost is high.

Summary of the invention

In order to overcome the problems referred to above that the prior art field exists, the purpose of this utility model is, a kind of circular tensioning member side cutting die is provided, and it is irregular effectively to solve cutting shoulder, and quality be cannot say for sure to demonstrate,prove; Production efficiency is low; Problems such as short, fragile, production cost height of otch section life-span.

The circular tensioning member side cutting die that the utility model provides, it comprises part of the upper die, drift part, part of the lower die, the part of the upper die comprises upper bolster, goes up holding pad, limited post; The part of the lower die comprises die shoe, interior binder block, lower stripper, counterdie back-up block, the lower end of binder block in lower stripper is fixedly connected on; The punch branch comprises that side is cut drift, gone up pushing block, the fixing edge of a knife outward, and last pushing block is fixedlyed connected with upper bolster, and fixedly the edge of a knife is fixedlyed connected with the counterdie back-up block outward, and the both sides that side is cut drift are provided with edge of a knife train wheel bridge, edge of a knife lower plate.The drift part is provided with 8 sides and cuts drift, is 45 ° and surrounds circular evenly distribution.

The circular tensioning member side cutting die that the utility model provides, its beneficial effect are, compared with prior art, can make production efficiency improve 2 times, and the life-span of mould was improved 4-5 doubly more originally, guaranteed that cutting shoulder is neat, improved quality, obtained good economic benefit.

Description of drawings

Fig. 1 is the overall structure schematic diagram of an embodiment of the utility model;

Mark among the figure:

1. upper bolster; 2. go up holding pad; 3. side is cut drift; 4. go up pushing block; 5. spring; 6. edge of a knife train wheel bridge; 7. edge of a knife lower plate; 8. interior binder block; 9. lower stripper; 10. spring; 11. spring; 12. workpiece; 13. limited post; 14. spring; 15. the fixing edge of a knife outward; 16. die shoe; 17. counterdie edge of a knife fixed head; 18. counterdie back-up block.

The specific embodiment

With reference to the accompanying drawings, in conjunction with an embodiment, the circular tensioning member side cutting die to the utility model provides is described in detail.

Embodiment

With reference to Fig. 1, the circular tensioning member side cutting die of present embodiment, it comprises part of the upper die, drift part, part of the lower die, the part of the upper die comprises upper bolster 1, goes up holding pad 2, limited post 13; The part of the lower die comprises die shoe 16, interior binder block 8, lower stripper 9, counterdie back-up block 18, the lower end of binder block 8 in lower stripper 9 is fixedly connected on; The punch branch comprises that side is cut drift 3, gone up pushing block 4, the fixing edge of a knife 15 outward, and last pushing block 4 is fixedlyed connected with upper bolster 1, and fixedly the edge of a knife 15 is fixedlyed connected with counterdie back-up block 18 outward, and the both sides that side is cut drift 3 are provided with edge of a knife train wheel bridge 6, edge of a knife lower plate 7; Punch is arranged with 8 sides and cuts drift 3, is 45 ° and surrounds circular evenly distribution.

The workpiece 12 that has stretched is placed in the matrix cavity of the outer fixedly edge of a knife 15, take off down the material piece 9 above, patrix is descending, spring 11 compressions above the interior binder block 8 and the following material 9 following springs 10 that take off compress simultaneously, it is descending together to drive workpiece, shift workpiece onto height that side cut needs, patrix limited post 13 contacts with counterdie edge of a knife fixed head 17 upper surfaces; Patrix continues descending, spring 5 compressions, and last pushing block 4 utilizes the inclined-plane to promote 8 sides and cuts drift 3, carries out periphery blank simultaneously, when mould goes downwards to bottom dead centre, with the material cut-out of workpiece periphery; Then, mould is up, and spring 5 discharges, and last pushing block 4 is up, and side is cut drift 3 and return under the effect of spring 14.Mould continues up, and spring 11 and spring 10 discharge, and workpiece floats under the effect of following floating block 9, and workpiece is taken out.
