Description
Technical field
The utility model relates to a kind of machining technique, refers in particular to a kind of cold punching die preventing V-arrangement bending to be out of shape.
Background technology
In cold stamping machined is produced, the product needed for client is multifarious, and some product structures are complicated and also have high-precision requirement to the polishing scratch of bending size and folding surface.Production unit, carrying out adding man-hour for these products with particular/special requirement above, can adopt V knife structure often at the processing mold of design.Asymmetric for some specialities bending edges, bending edges size short (being usually less than 3MM) on one side, dimension precision requirement is high, although have employed V knife structure, bending edges is too short causes both sides cannot binder simultaneously, easily form short and small folding surface turnup after bending, thus cause bending effect bad; This is ubiquitous processing problems in punching press industry.Therefore how to solve bending part bending edges short and small cause bending bad and exist certified products this difficult problem lower, just become in industry machining need solve problem.
Utility model content
The purpose of the present utility model: be intended to propose a kind of novel cold punching die preventing V-arrangement bending to be out of shape, both can help the accurate location processing tablet, and also can improve the punching press qualification rate of processing work simultaneously.
This cold punching die preventing V-arrangement bending to be out of shape, comprise upper bolster 1, through the patrix V cutter 4 that patrix connecting bolt 15 is fixedly connected with upper bolster, and and upper bolster, the counterdie base 9 that patrix V cutter correspondence is arranged and the die shoe 10 be stacked in successively on counterdie base, the left concave template 12 of lower bolster 11, right concave template 6, right concave template 6 is wherein through the lower bolster 11 of a gim peg 7 with bottom, die shoe 10 is concatenated into one, it is characterized in that: several feeding pressure mechanism A is inlayed in described being arranged between the left concave template of die shoe upper surface and right concave template, described feeding pressure mechanism A is by the trapezoidal insert 14 be directly placed between left concave template and right concave template and be arranged on trapezoidal insert 14 bottom, the push rod 5 being arranged in lower bolster 11 1 through hole and the hard spring 8 being arranged on lower bolster 10 1 through hole are formed.
The side of described trapezoidal insert 14 is provided with the bending slope angle matched with patrix V cutter.
Described left die is provided with product design positioning insert 16.
According to this cold punching die preventing V-arrangement bending to be out of shape that above technical scheme proposes, by the feeding pressure mechanism set up in the counterdie of original V knife mold, when making the decline of patrix V cutter, contact work piece upper surface, this feeding pressure mechanism withstands workpiece simultaneously, prevents workpiece deformation; When patrix V cutter drops to dead point, the feeding pressure mechanism on counterdie and patrix V cutter push down processing work simultaneously, through the bending R that both coordinate formation one complete.

Detailed description of the invention
This cold punching die preventing V-arrangement bending to be out of shape, it is a kind of inventive improvements to existing conventional V knife mold.
Further describe the utility model below in conjunction with Figure of description, and provide embodiment of the present utility model.
As Fig. 1, the 2 this cold punching dies preventing V-arrangement bending to be out of shape provided, comprise upper bolster 1, through the patrix V cutter 4 that patrix connecting bolt 15 is fixedly connected with upper bolster, and and upper bolster, the counterdie base 9 that patrix V cutter correspondence is arranged and the die shoe 10 be stacked in successively on counterdie base, the left concave template 12 of lower bolster 11, right concave template 6, right concave template 6 is wherein through the lower bolster 11 of a gim peg 7 with bottom, die shoe 10 is concatenated into one, it is characterized in that: several feeding pressure mechanism A is inlayed in described being arranged between the left concave template of die shoe upper surface and right concave template, described feeding pressure mechanism A is by the trapezoidal insert 14 be directly placed between left concave template and right concave template and be arranged on trapezoidal insert 14 bottom, the push rod 5 being arranged in lower bolster 11 1 through hole and the hard spring 8 being arranged on lower bolster 10 1 through hole are formed.
The side of described trapezoidal insert 14 is provided with the bending slope angle matched with patrix V cutter; Can ensure that workpiece 13 reaches certain bending angle R according to the requirement of design by the design of this cooperation.
Described left die is provided with product design positioning insert 16, and the location being conducive to workpiece to be machined is placed.
The schematic diagram of two steps that what Fig. 3 and Fig. 4 provided is when adopting the cold punching die originally preventing V-arrangement bending to be out of shape to carry out work pieces process.
State during V rolls over step 1 that what Fig. 3 provided belong to.Now patrix V cutter decline, touch workpiece raw-material while, counterdie material pressing device withstands raw material (workpiece) simultaneously, prevents raw material to be out of shape.
State during V rolls over step 2 that what Fig. 4 provided belong to.When now patrix V cutter drops to dead point, raw material (workpiece) pushed down by counterdie material pressing device and patrix V cutter simultaneously, make workpiece form a complete bending R; Reach the final machine-shaping object of workpiece.
Be more than of the present utility model a kind of embodiment that the present inventor provides according to mentality of designing, therefore all similar designs according to above-mentioned ideas put forward, all should belong to the category of the utility model protection.
