Description

A kind of auto parts multi-station progressive die tool

Technical field

The utility model relates to a kind of diel, especially a kind of mould that is used to produce automobile 6JD type part.

Background technology

Modern industry is produced, and complicated auto parts mainly adopt diel to produce.At present the operation that relates to of the 6JD type part in the automobile industry is more, and the requirement of precision is very high again, if adopt single die or composite membrane commonly used, the cost height, efficient is low, the quality instability of product, to operator's competency profiling than higher.

The utility model content

The purpose of this utility model is to provide a kind of multi-station progressive die tool that can realize automated production automobile 6JD type part, enhances productivity, and reduces production costs, and improves production environment, eliminates safe hidden trouble.

The technical solution of the utility model is: a kind of auto parts multi-station progressive die tool, comprise cope match-plate pattern, punch retainer, stripper, the floating life stock guide, guide pillar, lower bolster wherein install to be sheared punch, first piercing punch, second successively and is sheared punch, draws dark punch, the 3rd shears punch, second piercing punch, the punch that bends, shears punch at last on punch retainer; Described punch retainer is fixed on the cope match-plate pattern by upper die plate; Stripper is connected with cope match-plate pattern by little guide pillar; Stock guide floating life be installed on the counterdie backing plate successively, sheared die plate insert, first punching concave die is inserted, second shear die plate insert, draw dark die plate insert, the 3rd shear die plate insert, second punching concave die insert, bend die plate insert, shear die plate insert at last; Described counterdie backing plate is fixed on the lower bolster by the counterdie back-up block; Cope match-plate pattern is involutory by guide pillar and lower bolster; Guide pillar is fixed on the lower bolster.

The utility model adopts CAD, has made up part and Die CAD model, shortens product development cycle.In a secondary mould, can finish multi-step forming processes such as comprising stamping-out, bending, pull and stretch and shaping, reduced turnover and the resetting process of using how secondary mould.A plurality of die plate inserts are installed on the counterdie backing plate, easy to maintenance, quick; Improved production efficiency, reduced production costs.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As Fig. 1, the production auto parts multi-station progressive die tool that the utility model provides, comprise cope match-plate pattern 8, punch retainer 3, stripper 9, the stock guide 1 of growing floating on water, guide pillar 6, lower bolster 10 is wherein installed successively on punch retainer 3 and is sheared punch, first piercing punch 2, the second shearing punch, draws dark punch, the 3rd shearing punch, second piercing punch, the punch that bends, shears punch at last, and punch retainer 3 is fixed on cope match-plate pattern 8 by upper die plate 5; Stripper 9 is connected with cope match-plate pattern 8 by little guide pillar 7; Stock guide 1 floating life be installed on counterdie backing plate 12 successively, sheared die plate insert, first punching concave die is inserted, second shear die plate insert 4, draw dark die plate insert, the 3rd shear die plate insert, second punching concave die insert, bend die plate insert, shear die plate insert at last; Counterdie backing plate 12 is fixed on the lower bolster 10 by counterdie back-up block 11; Cope match-plate pattern 8 is involutory by guide pillar 6 and lower bolster 10; Guide pillar 6 is fixed on the lower bolster 10.

During work, once lead, carry out the secondary guiding by buoyance

lift stock guide

1 and 7 pairs of each punch of little guide pillar and die, thereby guarantee the operating accuracy of a whole set of mould by guide pillar 6 and the guide pin bushing that is installed on the cope match-plate pattern 8; Carry out self-feeding by feeder, the correcting nail carries out the correcting second time to billot, guarantees the pushing precision of billot, thereby has guaranteed the forming accuracy of product parts.

The production auto parts multi-station progressive die tool that the utility model provides is on the basis of computer simulation model, finishes the expanded view design and the reasonable stock layout of part; Employing numerical control device processing guarantees profile, type hole, the die cavity of protruding, each operation of die, the position of locating hole, thereby reaches the shortening product development cycle, guarantees the product one-shot forming.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
