Abstract

The utility model relates to a stamping die, in particular to a stamping die capable of reconstructing various shapes. The stamping die comprises an upper die holder part and a lower die holder part;the upper die holder is provided with a die handle and a male die fixing plate; the male die fixing plate is fixed on the upper die holder by a bolt; a plurality of base body punches are arranged on the male die fixing plate; a connecting bolt with an edge pressing spring at the bottom is arranged on the male die fixing plate; the lower part of the connecting bolt is connected with an edge pressing ring; a female die fixing plate is fixed on the lower die holder by a bolt and is provided with a female die components including straight-strip shaped components and arc-shaped components; the twoends of the straight-strip shaped components and the arc-shaped components are respectively in the mortise and tenon joint structure; and blanks and elastic pads are arranged between the female die and the end pressing ring. The utility model has the advantages that the male die can be reconstructed by adjusting the extending distance of each base body punch on the female die fixing plate, the female die of various shape can be reconstructed by replacing different female die components, and the tension and the bend processing of a stamping element with different shapes can be completed on thesame set of dies after the female die is fixed on the female die fixing plate.

Description

The diel of the multiple shape of restructural

Technical field

The utility model relates to a kind of diel, specifically relates to the diel of the multiple shape of a kind of restructural, belongs to pressure technological equipment for making technical field.

Background technology

Increase day by day along with novel lightweight materials such as high strength steel, aluminium alloy, dual phase steel, welding plate application percentage in body outer skin and structural member production, especially harsh day by day to body outer skin form accuracy and car load assembling quality requirement, press for test method and equipment that a cover can reflect whole deformation history of material and practical distortion behavior as far as possible, to disclose the deformational behavior of various materials under specific molding condition.And prior art is still forming limit and the constitutive relation of determining material by the unidirectional and biaxial tensile test of plate, the actual deformed state that obviously can not truly reflect material, the accurate judge that causes the error of the basic data that obtains big, has influence on manufacturing deficiency in the follow-up drawing prediction of quality.

In addition, mould generally is that a mold only is applicable to the punch process with a collection of part, a certain procedure as the special equipment that the given shape part punching is shaped, and when the part shape structure changes, just need manufacture and design the new mould of a cover for it; Even if for can or finishing the compound die and the progressive die of multi-pass punch process in the process-cycle at a punching stroke, also face defectives such as mould structure complexity, dismounting inconvenience, design and manufacture cost height, therefore be not suitable for current jobbing work and the diversified market demands of user's request.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of and come the reconstruct punch by the outreach of regulating each element body drift on the punch retainer, by die is constructed in the reorganization of die block upper cavity die assembly, on same set of mould, can finish the diel of the multiple shape of restructural of difformity stamping parts pull and stretch and bending machining.

The utility model is realized with following technical scheme: the diel of the multiple shape of a kind of restructural, it includes upper bolster part and die shoe part, it is characterized in that: die shank is arranged on the upper bolster and be fixed on punch retainer on the upper bolster by screw, several element body drifts are arranged on the punch retainer, there is the bottom to have the connecting bolt of flanging spring on the punch retainer, the connecting bolt bottom is connected with blank holder, be fixed with die block by screw on the die shoe, the die assembly is arranged on the die block, the die assembly has vertical bar shaped assembly and arc assembly, the two ends of vertical bar shaped assembly and arc assembly are respectively joinery and its construction, and blank and elastomeric pad are arranged between die and the blank holder.

Die shank is arranged on the described upper bolster and be fixed on punch retainer on the upper bolster by screw, be distributed with the threaded stepped hole in bottom by 9 * 9 array formats on the punch retainer, 1 element body drift (3) is housed in each stepped hole, have the bottom to have the connecting bolt of flanging spring on the punch retainer, the connecting bolt bottom is connected with blank holder.

Be fixed with die block by screw on the described die shoe, the die assembly is arranged on the die block, the die assembly has vertical bar shaped assembly and arc assembly, and the two ends of vertical bar shaped assembly and arc assembly are respectively joinery and its construction, and blank and elastomeric pad are arranged between die assembly and the blank holder.

The utility model has the advantages that: this diel is to come the reconstruct punch by the outreach of regulating each element body drift on the punch retainer, by changing the die that different die assembly restructurals go out multiple shape, after being fixed on die on the die block, can on same set of mould, finish the diel of the multiple shape of restructural of difformity stamping parts pull and stretch and bending machining.This technology both can be used for the trial-production of the small quantities of product of single-piece, also can be used for the experimental study of actual shaped state of new material and forming property.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is that the utility model master cuts open structural representation;

Fig. 2 is the utility model vertical bar shaped die modular construction schematic diagram;

Fig. 3 is the structural representation of the utility model arc die assembly;

Among the figure: 1, upper bolster, 2, screw, 3, the element body drift, 4, die shank, 5, shop bolt, 6, punch retainer, 7, attachment bolt, 8, the flanging spring, 9, blank holder, 10, elastomeric pad, 11, blank, 12, die, 13, die block, 14, die shoe.

The specific embodiment

As shown in the figure: the diel of the multiple shape of a kind of restructural, it includes upper bolster 1 and die shoe 14, die shank 4 is arranged on the upper bolster and be fixed on punch retainer 6 on the upper bolster by screw 2, several element body drifts 3 are arranged on the punch retainer, there is the bottom to have the connecting bolt 7 of flanging spring 8 on the punch retainer, the connecting bolt bottom is connected with blank holder 9, be fixed with die block 13 by screw on the die shoe 14, die assembly 12 is arranged on the die block, the die assembly has vertical bar shaped assembly and arc assembly, the two ends of vertical bar shaped assembly and arc assembly are respectively joinery and its construction, and blank 11 and elastomeric pad 10 are arranged between die 12 and the blank holder 9.

Die shank 4 is arranged on the described upper bolster and be fixed on punch retainer 6 on the upper bolster by screw 2, be distributed with the threaded stepped hole in bottom by 9 * 9 array formats on the punch retainer, in order to corresponding element body drift to be installed, and according to the shape facility of drawing part, regulate the overhang of element body drift, to reconstruct the punch profile with respect to punch retainer.

When reconstruct and mounted mold work, identical with the operation principle of common diel, promptly the part of the upper die is displaced downwardly to blank holder and compresses blank under the drive of press ram, and slack; Press ram continues to move down then, by the compression of flanging spring 8, finishes actual stamping process; After the drawing, retract journey on the press ram, finish work such as the demoulding, discharging successively.
