Abstract

The utility model discloses a die suitable for pressing longitudinal beams of multiple varieties. The die is composed of a female die body and a male die body and is characterized in that insert combination structures are adopted by the female die body and the male die body, the female die body comprises a female die mounting base (12), a female die insert (11) is arranged on the female die mounting base (12), the male die body comprises a male die mounting base (22), a male die insert (21) is arranged on the male die mounting base (22), the female die insert (11) and the male die insert (21) are of a left-and-right turning structure, and locating blocks (31) are arranged at the front end of the female die insert (11) and the front end of the male die insert (21). When the left /right beam is formed, one set of die is shared, therefore, cost of one set of longitudinal beam die is saved, and production of the longitudinal beams of the multiple varieties can be met; the locating blocks are arranged at the front end of the female die insert and the front end of the male die insert, the phenomenon that when the longitudinal beams and lining beams of different lengths are pressed, the die needs to be moved is avoided, the longitudinal beams of different lengths from 5 m to 12 m are formed, and problems of unbalance loading and the like cannot happen.

Description

A kind of mould of applicable many kinds of compacting longeron

Technical field:

The utility model relates to machinery and Stamping Die Technology field, is a kind of mould of applicable many kinds of compacting longeron specifically.

Background technology:

Automobile longitudinal girder part is a typical U-shaped part and symmetrical structure, its complex-shaped, depth of section changes greatly, surface quality requires high, in producing at present, the shaping of high-strength steel sheet there will be a lot of problems, can not ensure parts quality and dimensional accuracy, left-right longeron respectively needs a mold conventionally, can not use mutually, bring larger investment to production process, cause production and administration high in cost of production problem.

Utility model content:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and provide a kind of mould of applicable many kinds of compacting longeron, adopt a mold by the method for inserting and exchanging, can suppress the left-right longeron of many kinds, the rolled-up stock that mainly solves existing automobile longitudinal girder can not be ensured the quality of products and size, investment are large and high in cost of production problem.

The technical solution of the utility model is: a kind of mould of applicable many kinds of compacting longeron, be made up of die and punch, its special character is, the whole combining structures of inserting that adopt of described die and punch, described die comprises die mount pad, on die mount pad, establishes die plate insert; Described punch comprises punch mount pad, on punch mount pad, establishes punch insert; Described die plate insert and punch insert are left and right overturn structure; Described die plate insert and punch insert front end are established locating piece.

Compared with the prior art the mould of a kind of applicable many kinds of compacting longeron described in the utility model has following good effect, 1, because the structure of punch, die is the form that left and right upset is inserted, in the time that left/right beam is shaped, make left/right beam share a mold, thereby reduced the cost of a set of longeron mould; 2, establish locating piece at die plate insert and punch insert front end, adopt locating piece form with by forcing press according to the different pressure classifications of realizing of pressing component length, while avoiding suppressing different length longeron, lining beam, need to move moulds, the longeron of 5 ~ 12 meters of different lengths of shaping, there will not be the problems such as unbalance loading.Brief description of the drawings:

Fig. 1 is the utility model cavity die structure schematic diagram;

Fig. 2 is the utility model punch structure schematic diagram;

Fig. 3 is the sectional drawing after the utility model die and punch combination;

Fig. 4 is the utility model front end positioning structure schematic diagram.

Detailed description of the invention:

Below in conjunction with drawings and the specific embodiments, the utility model is described in further details; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.

Embodiment 1, referring to Fig. 1,2,3,4, need to process die and punch according to design, and die and punch all adopt the combining structure of inserting; On the die mount pad 12 of die, die plate insert 11 is installed, on the punch mount pad 22 of punch, punch insert 21 is installed, die plate insert 11 and punch insert 21 are left and right overturn structure, at die plate insert 11 and punch insert 21 front ends, locating piece 31 are installed.

The mould of a kind of applicable many kinds of compacting longeron described in the utility model, on mould structure, adopt modular combination technique, when left/right beam is shaped, punch, cavity die structure are designed to the form of left and right upset punch insert and die plate insert, make left/right beam share a mold, thereby reduced the cost of a set of longeron mould; The straight section part of remodeling 2 kinds of thick longeron products of material (8.5+7 and 8+6) realizes by cushioning after changing punch insert and die installing plate, can meet the production of more than 40 longeron kind; Longeron, lining beam length change in size scope are large, all design front end locating piece, adopt locating piece form with by forcing press according to the different pressure classifications of realizing of pressing component length, while avoiding suppressing different length longeron, lining beam, need to move moulds, the longeron of 5 ~ 12 meters of different lengths of shaping, there will not be the problems such as unbalance loading.

Claims

1. one kind is applicable to the mould of many kinds of compacting longeron, be made up of die and punch, it is characterized in that, described die and punch all adopt the combining structure of inserting, described die comprises die mount pad (12), establishes die plate insert (11) on die mount pad (12); Described punch comprises punch mount pad (22), establishes punch insert (21) on punch mount pad (22); Described die plate insert (11) and punch insert (21) are left and right overturn structure; Described die plate insert (11) and punch insert (21) front end are established locating piece (31).
