Abstract

The utility model relates to the technical field of die structures, and particularly relates to a flanging die wear reducing device. The device comprises an upper die holder and a lower die holder, wherein the lower end of the upper die holder is connected with a punch, an upper die spring is arranged between the upper die holder and the punch, the upper part of the lower die holder is connected with a fixed plate arranged corresponding to the punch, and a lower die spring is arranged between the fixed plate and the lower die holder. Both sides of the fixed plate are provided with die flanging blocks, wherein the die flanging blocks are provided with die reducing devices. Each die reducing device comprises fixed blocks arranged on both sides of the die flanging blocks. Three round rods are arranged between the two fixed blocks, wherein the three round rods can mutually rotate. When the device is used, by arranging three round rods which mutually rotate with the aid of friction on the die flanging blocks, the flanging die wear reducing device enables materials to move downward along the rotation of the round rods in a molding process instead of sliding between the die flanging blocks and the punch, so that the surface of a workpiece is not damaged by extruding.

Description

A kind of flanging mould anti-attrition device

Technical field

The utility model relates to the mould structure technical field, relates in particular to a kind of flanging mould anti-attrition device.

Background technology

At present, when utilizing the work of bender flanging, need to use Bending Mould and flanging mould; The mould that is used for flanging in the prior art mainly includes sharp knife mould and flattening die, and these two kinds of moulds are formed by upper die and lower die, and upper die and lower die are provided with corresponding wedge; The working face of flattening die is two horizontal planes; Counterdie and die shoe fix, patrix and bender slide block relative fixed, and slide block pumps; Be placed under the interaction of the workpiece wedge working face between the upper die and lower die, the workpiece bending; When further flanging, need process once more with flattening die, add man-hour, the workpiece of bending is put on the working face of flattening die counterdie, slide block drives the patrix action, and the both sides of bending are pressed against together each other; Above-mentioned sharp knife mould and flattening die also can be arranged on the counterdie, and wedge face and plane promptly are set on the different facial of counterdie, or at the diverse location of the identical faces of counterdie wedge face and plane are set.

But above-described sharp knife mould and flattening die are at the workpiece that has coating to some surfaces; When Bending Processing; Can the coating of surface of the work be squeezed and hinder, the metal that can cause surface of the work to squeeze the injury like this gets rusty, and carries out coating once more as if the metal that surface of the work coating is squeezed the injury and handles; Can produce situation about not being inconsistent with original coating, and this complicated operation.

Summary of the invention

The purpose of the utility model is to provide a kind of flanging mould anti-attrition device, and it can effectively solve the flanging moulding and squeeze the problem of hindering surface of the work coating.

For realizing above-mentioned purpose, the utility model adopts following technical proposals:

A kind of flanging mould anti-attrition device; Comprise upper bolster and die shoe, said upper bolster lower end is connected with punch, is provided with the patrix spring between said upper bolster and the said punch; Said die shoe top is connected with the fixed head with the corresponding setting of said punch; Be provided with the counterdie spring between said fixed head and the said die shoe, the both sides of said fixed head are equipped with the folding module, and said folding module is equiped with and subtracts die device; The said die device that subtracts comprises the fixed block of being located at said folding module both sides, is provided with three poles that can rotate each other between said two fixed blocks.

Wherein, said fixed block is fixedly connected with said folding module through bolt.

Wherein, the below of the corresponding said fixed head in said die shoe top is provided with limited post.

Wherein, said pole is a tungsten bar.

Wherein, all be connected between said upper bolster and the said punch and between die shoe and the said fixed head through screw rod.

The utility model beneficial effect: the utility model comprises upper bolster and die shoe; Said upper bolster lower end is connected with punch; Be provided with the patrix spring between said upper bolster and the said punch, said die shoe top is connected with the fixed head with the corresponding setting of said punch, is provided with the counterdie spring between said fixed head and the said die shoe; The both sides of said fixed head are equipped with the folding module; Said folding module is equiped with and subtracts die device, and the said die device that subtracts comprises the fixed block of being located at said folding module both sides, is provided with three poles that can rotate each other between said two fixed blocks; In use, through being equiped with three poles at folding on the module, pole rotates under function of friction each other, thereby makes material in forming process, roll and move down along pole, rather than between folding module and punch, slides, and does not hinder surface of the work so can not squeeze.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is carried out detailed description.

As depicted in figs. 1 and 2, a kind of flanging mould anti-attrition device comprises upper bolster 1 and die shoe 2; Said upper bolster 1 lower end is connected with punch 3, is provided with patrix spring 4 between said upper bolster 1 and the said punch 3, and said die shoe 2 tops are connected with the fixed head 5 with said punch 3 corresponding settings; Be provided with counterdie spring 6 between said fixed head 5 and the said die shoe 2, all be connected through screw rod between said upper bolster 1 and the said punch 3 and between die shoe 2 and the said fixed head 5, the both sides of said fixed head 5 are equipped with folding module 7; Said folding module 7 is equiped with and subtracts die device; The said die device that subtracts comprises the fixed block 8 of being located at said folding module 7 both sides, is provided with three poles that can rotate each other 9 between said two fixed blocks 8, and said pole 9 is a tungsten bar; The utility model in use; Through being equiped with three poles 9 at folding on the module 7, pole 9 rotates under function of friction each other, thereby makes material in forming process, roll and move down along pole 9; Rather than between folding module 7 and punch 3, slide, do not hinder surface of the work so can not squeeze.

In the present embodiment; Said fixed block 8 is fixedly connected with said folding module 7 through bolt, and said fixed block 8 and said folding module 7 also can be other connection except the employing bolt is connected; As long as can make said fixed block 8 fixing, guarantee that the said die device operate as normal that subtracts gets final product with folding module 7.

In the present embodiment; The below of the corresponding said fixed head 5 in said die shoe 2 tops is provided with limited post 10; Said limited post 10 is used to limit the distance that moves down of said fixed head 5; The distance of fixed head 5 and said limited post 10 can be provided with the stroke of fixed head 5 according to the bending distance and the punch 3 of required bending workpieces flexibly.
