Abstract

The utility model discloses the longeron drawing and moulding mould of a kind of upper binder, including punch, die and blank holder, blank holder is sheathed on punch, die is located at above blank holder, its lower surface contacts with blank holder upper surface, also including the upper material pressing core being located in die, the upper end of upper material pressing core is provided with several nitrogen spring, and the lower surface of upper material pressing core contacts with the upper surface of punch.This utility model can effectively solve the problem that the defect that part is wrinkling, improves the surface quality of part, and promotes the precision of part.

Description

A kind of longeron drawing and moulding mould of upper binder
Technical field
This utility model relates to diel field, more particularly, it relates to the longeron draw forming die of a kind of upper binder Tool.
Background technology
The upper binder drawing die of part is the instrument that is embodied as of forming parts technique, and all sheet metal components of automobile are all logical Cross certain drawing mold structure to realize actual production.
In the prior art, general drawing mold structure is all made up of, typically punch, die, three parts of blank holder Blank holder is designed as the outside binder of part, is difficult to solve the situation that interiors of products is wrinkling, various due to body in white part shape Property, unavoidably have the part of some end face big rise and falls.Owing to using conventional drawing means, it is impossible to the basic product that solves rises Wrinkle problem, thus product appearance surface quality cannot be ensured, the wrinkling situation more serious simultaneously for high-strength steel beam piece can be big Big increase die trial difficulty, thus element precision cannot be ensured.
Utility model content
For defect present in above-mentioned prior art, the purpose of this utility model is to provide the longeron of a kind of upper binder and draws Prolong mould, it is possible to effectively solve the defect that part is wrinkling, improve the surface quality of part, and promote the precision of part.
For achieving the above object, this utility model adopts the following technical scheme that
The longeron drawing and moulding mould of a kind of upper binder, including punch, die and blank holder, blank holder is sheathed on punch On, die is located at above blank holder, and its lower surface contacts with blank holder upper surface, also includes the upper material pressing core being located in die, The upper end of upper material pressing core is provided with several nitrogen spring, and the lower surface of upper material pressing core contacts with the upper surface of punch.
Described upper material pressing core includes on first material pressing core on material pressing core and second.
On described first, on material pressing core and second, material pressing core upper end is all additionally provided with several safe spacing bolt.
Described punch is equipped with guiding with blank holder, blank holder on die, the die contact surface with upper material pressing core.
In technique scheme, this utility model passes through press push rod jack-up blank holder, and die is descending to be connect with blank holder Pressing plate, when die goes downwards to certain stroke, upper material pressing core contacts binder with punch, it is achieved the while of inside and outside, binder draws The process prolonged, thus can effectively control part wrinkling, improve accessory appearance surface quality.
Accompanying drawing explanation
Fig. 1 is that part creases easily the schematic diagram in region;
Fig. 2 is the schematic diagram arranging two upper binder regions on part;
Fig. 3 is the structural representation that in this utility model, die combines with blank holder;
Fig. 4 is the structural representation of this utility model convex mould and the combination of upper material pressing core;
Fig. 5 is the sectional view of this utility model side.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings with embodiment.
Incorporated by reference to shown in Fig. 1, being the present embodiment floor side member part drawing, in figure, a position is district the most wrinkling on part Territory, therefore tackle this region and carry out the drawing of upper binder.
Incorporated by reference to shown in Fig. 2, the present embodiment is designed with b part and the upper binder drawing region of c part two.
Incorporated by reference to shown in Fig. 3 and Fig. 4, the longeron drawing and moulding mould of a kind of upper binder provided by the utility model, bag Including punch 1, die 2 and blank holder 3, blank holder 3 is sheathed on punch 1, and die 2 is located at above blank holder 3, its lower surface and pressure Flange 3 upper surface contacts, and also includes the upper material pressing core 4 being located in die 2, and the upper end of upper material pressing core 4 is provided with several nitrogen spring 5, the lower surface of upper material pressing core 4 contacts with the upper surface of punch 1, and wherein, on punch 1 stationary press following table, die 2 is arranged on On press upper table surface, the push rod of following table is as the pressure source of blank holder 3, and die 2 is descending, and die 2 contacts with blank holder 3, pressure Moving on certain stroke after material, nitrogen spring 5, as the pressure source of upper material pressing core 4, makes material pressing core 4 contact binder with punch 1, Thus reach the inside and outside binder simultaneously of part and carry out the process of drawing.
It is also preferred that the left according to the shape size of part in embodiment, described upper material pressing core 4 includes material pressing core 401 on first With second on material pressing core 402.
It is also preferred that the left on material pressing core 401 and second, material pressing core 402 upper end is all additionally provided with several safe spacing on described first Bolt 6, to ensure the safety during die trial.
It addition, nitrogen spring 5 and safe spacing bolt 6 in this utility model can be reused, therefore, book is practical Compared with novel and existing mould, cost is little, it is essential that this utility model fundamentally solves part Wrinkling problem.
Incorporated by reference to shown in Fig. 5, punch 1 and blank holder 3, blank holder 3 and die 2, all set between die 2 and upper material pressing core 4 Put guiding 7, in order to ensure the kinematic accuracy between all parts.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new Type, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, to the above The change of embodiment, modification all will fall in Claims scope of the present utility model.
