Abstract

The utility model relates to a stamping die, especially high -precision stamping die, including upper die base, profiled sheeting, buoyant board, die holder and pipe position shaping mold insert, the profiled sheeting is fixed on the upper die base through the shaping backing plate, the buoyant board is installed on the die holder, pipe position shaping mold insert is fixed on the die holder, and passes the buoyant board, and pipe position shaping mold insert is equipped with four, and the symmetric distribution is in the both sides of buoyant board, and the distance between the pipe position shaping mold insert is less than the width in material area. The utility model provides a that high -precision stamping die safeguards is convenient, simple structure is stable, low in production cost, in the die face complicacy and realize the precision location under the high circumstances of product required precision.

Description

High-precision stamping mould
Technical field
This utility model is related to a kind of stamping mold, especially high-precision stamping mould.
Background technology
Mould is described as the mother of industry, and car industry is again the important representative of industrial development, with automobile at a high speed, it is comfortable, Stylization development, body structure will be increasingly sophisticated, it is desirable to which mould to maximization, complication, high-precision matter direction are developed.Stamping mold Manufacture be broadly divided into product analyses, determine the steps such as process program, structure design, processing and manufacturing, assembly and adjustment.Due to some Stamping parts Product Precision requires higher, needs to keep a grip on material strip in feeding punching course, makes material strip in molding or shear history Do not rock, if using traditional pipe bit architecture, some gaps are still left at pipe position, can still produce when punching press and rock, nothing Method meets high-precision requirement, and on die trial uncontrollable impact is produced, and extends the manufacturing cycle of mould.
Utility model content
To solve the above problems, this utility model provides a kind of positioning precision high high-precision stamping mould, particular technique Scheme is:
High-precision stamping mould, including upper bolster, dieplate, buoyant plate, die shoe and pipe position molding mold insert;The molding Plate is fixed on upper bolster by molding backing plate, and the buoyant plate is arranged on die shoe;The pipe position molding mold insert is fixed on On die shoe, and through buoyant plate, molding mold insert in pipe position is provided with four, is symmetrically distributed in the both sides of buoyant plate, pipe position molding edge Width of the distance between the part less than material strip.
The pipe position molding mold insert includes fixed column and the shaping column at the top of fixed column;The fixed column is fixed on down On die holder, the face that the shaping column is contacted with material strip is semi circular surface, is provided with molding cambered surface at the top of shaping column, the semi circular surface with Molding cambered surface connects.
After material strip reaches specified location, molding mold insert in pipe position first molds circular arc notch in material strip scrap area, utilizes Totally four circular arc notches keep a grip on material strip to complete precision positioning on both sides, punch forming again after being accurately positioned, than traditional single straight flange Pipe position accurate positioning, space is saved.Molding cambered surface is more prone to circular arc notch molding.Semi circular surface is extruded with material strip, in material strip Extrude circular arc notch in edge.If the distance between pipe position molding mold insert just loses not less than the width of material strip, pipe position molding mold insert Effect is gone, therefore the distance between pipe position molding mold insert is necessarily less than the width of material strip.
It is primarily adapted for use in that die face is complicated and situation that Product Precision has high demands.It is little with taking up space, and is processed into This is low, the features such as pipe position effect is good.
, using hard material, service life is longer, and easy accessibility can reach section in maintenance or brand-new for pipe position molding mold insert The about purpose of cost and time.
This utility model provide high-precision stamping mould is easy to maintenance, simple and stable structure, low production cost, in mould Type face is complicated and Product Precision realizes that precision is positioned in the case of having high demands.
Description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the pipe position molding mold insert structural representation spacing to material strip;
Fig. 3 is the pipe position molding mold insert partial enlarged drawing spacing to material strip at I in Fig. 2.
Specific embodiment
In conjunction with description of the drawings specific embodiment of the present utility model.
As shown in Figure 1 to Figure 3, high-precision stamping mould, including upper bolster 1, dieplate 3, buoyant plate 4, die shoe 5 and pipe Position molding mold insert 6.
Dieplate 3 is fixed on upper bolster 1 by molding backing plate 2;Buoyant plate 4 is arranged on die shoe 5;Pipe position molding edge Part 6 is fixed on die shoe 5, and through buoyant plate 4, pipe position molding mold insert 6 is provided with four, is symmetrically distributed in the two of buoyant plate 4 The width of the distance between side, pipe position molding mold insert 6 less than material strip 8.
Pipe position molding mold insert 6 includes fixed column 61 and the shaping column 63 positioned at the top of fixed column 61;Fixed column 61 is fixed on On die shoe 5, the face that shaping column 63 is contacted with material strip 8 is semi circular surface 62, and the top of shaping column 63 is provided with molding cambered surface 64, semicircle Face 62 is connected with molding cambered surface 64.
When punch press is vertically down moved, upper bolster 1, molding backing plate 2, dieplate 3 are along punch press movement in vertical direction, contact To material strip 8 is pushed down during material strip 8, material strip 8 is held by buoyant plate 4 again, and pipe position molding mold insert 6 is run into when continuing to press down, material strip 8 The circular arc notch 9 that edge formation goes out in Fig. 3.When punch press returns to initial position, dieplate 3 and material strip 8 are separated, and complete once to rush Pressure.
, using hard material, service life is longer, and easy accessibility can reach in maintenance or brand-new for pipe position molding mold insert 6 Cost-effective and the time purpose.
