Abstract
The utility model discloses a thermal baffle blanking and punching die which comprises an upper die body and a lower die body. The upper die body comprises an upper die seat and an upper blanking assembly arranged on the upper die seat. The lower die body comprises a lower die seat and a lower blanking assembly used for being matched with the upper blanking assembly to locate, blank and punch workpieces. An annular boss is arranged on the bottom face of the upper die seat. The upper blanking assembly is arranged on an annular bottom face of the annular boss. According to the thermal baffle blanking and punching die, the bottom face of the upper die seat is connected with the upper blanking assembly through the annular face, so that blanking force can be diffused to a blanking machining annular area corresponding to the workpieces, a stress centralized part is enabled to be vertically opposite, rigid blanking is ensured, product quality is improved, procedures are reduced, and cost is reduced.
Description
Technical field
The utility model relates to a kind of blanking die, relates in particular to a kind of thermal baffle blanking and punching mould.
Background technology
Blanking die is a kind ofly to be installed on forcing press and by pressurization metal or nonmetal plate or section bar to be separated the technological equipment that obtains product, in batch process, obtained using widely, in modern industry production, occupy crucial status, common have a blanking die, perforating die, knife edge die, notch die, edger, parting die etc., the composite die that can finish twice or the above blank operation of twice on same station is simultaneously also arranged, as be used to process the blanking and piercing die of thermal baffle, blanking and piercing die of the prior art, its stamping-out reaction force mainly concentrates on product limit portion peripheral annular zone, and upper bolster generally is connected with forcing press by the die shank that is positioned at its center, blanking pressure concentrates on the central area, depart from the stamping-out reaction force, easily produce flutter during stamping-out, product easily produces burr, of poor quality, need back polishing finishing, the processing cost height.
Therefore, for addressing the above problem, need a kind of novel thermal baffle blanking and punching mould, blanking pressure is scattered in the annular region that the corresponding blanking of workpiece is processed, makes stressed concentrated part relative up and down, guarantee the rigidity stamping-out, improve the quality of products, reduce operation, reduce cost.
The utility model content
In view of this, the purpose of this utility model provides a kind of thermal baffle blanking and punching mould, upper bolster underrun ring surface is connected with last stamping-out assembly, blanking pressure can be scattered in the annular region of the corresponding blanking processing of workpiece, make stressed concentrated part relative up and down, guarantee the rigidity stamping-out, improve the quality of products, reduce operation, reduce cost.
Thermal baffle blanking and punching mould of the present utility model comprises that patrix is concrete and counterdie is concrete, and described patrix specifically comprises upper bolster and is installed on the last stamping-out assembly of described upper bolster; Described counterdie specifically comprise die shoe and be installed on described die shoe be used to cooperate the stamping-out assembly that workpiece is positioned and the following stamping-out assembly of blanking and punching processing; Described upper bolster bottom surface is provided with annular boss; Described upward stamping-out assembly is installed on the annular bottom surface of described annular boss.
Further, described go up the stamping-out assembly comprise the clamping plate that are fixed in the annular boss bottom surface and be installed on described clamping plate be used for accordingly workpiece is cut edge and the die of punching and towards pin and the expeller that workpiece carried out the elastic compression location; The inward flange of projection is consistent or be positioned at die in the direction outside the inward flange of projection in the direction along the inward flange of mould stamping-out direction projection and die for described annular boss;
Further, described annular boss is fixed in the upper bolster bottom surface by hollow backing plate and forms;
Further, described down stamping-out assembly comprise with expeller be relatively fixed up and down in described die shoe be used for workpiece is supported to cooperate die and to dash at workpiece and cut edge and the punch-die of punching and the be installed on die shoe relative up and down with die are used for needing crush-cutting limit portion to carry out the stripper plate of resiliency supported to workpiece;
Further, described die shoe is provided with and is used for guide pillar that upper bolster is vertically led; Corresponding guide pillar is provided with and is used for the guide pin bushing that is slidingly matched with guide pillar on the described upper bolster.
The beneficial effects of the utility model are: of the present utility model kind of thermal baffle blanking and punching mould, upper bolster underrun ring surface is connected with last stamping-out assembly, blanking pressure can be scattered in the annular region of the corresponding blanking processing of workpiece, make stressed concentrated part relative up and down, guarantee the rigidity stamping-out, improve the quality of products, reduce operation, reduce cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
