Abstract

The utility model discloses a bending edge rolling workpiece progressive die which comprises an upper die body and a lower die body. The upper die body comprises an upper die base, an upper base board, an upper clamping board, a back separation board and a stripper board, wherein the upper die base, the upper base board, the upper clamping board, the back separation board and the stripper board are sequentially arranged from top to bottom. The lower die body comprises a lower die board, a lower base board, a lower die base and a lower pad foot. The bending edge rolling workpiece progressive die is provided with a multi-position progressive punching die comprising a hole punching die, an edge cutting die A, a step-free die A, a bending die, an edge cutting die B, a step-free die B, a bending pressing die, a step-free die C, an edge rolling die, a step-free die D, a cutting die A and a cutting die B. According to the bending edge rolling workpiece progressive die, as the multi-position progressive punching die is utilized, the number of machines can be reduced, the number of operating workers is reduced, and production efficiency is improved.

Description

A kind of press-bending volume circular Curve progressive die

Technical field

The utility model relates to a kind of progressive die, is specifically related to a kind of press-bending volume circular Curve progressive die .

Background technology

Press-bending volume circular Curve 9 as shown in Figures 1 to 5, at present, process this press-bending volume circular Curve 9 and at least will pass through the manufacturing procedures such as punching, trimming, bending, press-bending, volume circle and cut-out, these manufacturing procedures respectively will be joined a machine tool, and each lathe at least needs a workman, just can complete the production of product.In this case, several lathes together power consumption and maintenance cost high, take plant area large, the noise of generation is large, and the workman who needs is many.In addition, in production process, half-finished number of turnover is too many, has strengthened the production cycle, therefore production efficiency is low.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of press-bending volume circular Curve progressive die, with the purpose that reaches minimizing equipment number of units, reduces the operator and enhance productivity.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of press-bending volume circular Curve progressive die, comprise upper die and lower die, and described patrix comprises upper bolster, upper padding plate, train wheel bridge, de-backboard and the stripper plate be arranged in order from top to down, and described counterdie comprises lower bolster, lower bolster, die shoe and bottom seat pad; The described progressive die is provided with the multi-station progressive stamping mould; Described diel comprise one perforating die, one A edger, the one empty step of A mould, one bender, one B edger, the one empty step of B mould, one bending die, the one empty step of C mould, together volume circle mould, the one empty step of D mould, one A knife edge die with together with the B knife edge die.

Preferably, described up stripper is provided with a plurality of blanking punches that are arranged in order by stamping procedure, and on described lower bolster, correspondence position is provided with the punching and blanking die be complementary with described blanking punch.

Preferably, described patrix is provided with the punching pin that a plurality of stamping-outs are used.

Preferably, described patrix is provided with several interior leads, and described counterdie is provided with and described lead fairlead one to one.

By technique scheme, a kind of press-bending volume circular Curve progressive die that the utility model provides, due to the multi-station progressive stamping mould that has adopted continuous punch forming, thereby can reduce equipment number of units, minimizing operator, and enhance productivity.
