Description
Technical field
The present invention relates to the manufacturing field of automobile panel, in particular to the drawing die of a kind of automobile panel and determination
The method of bead and plate position.
Background technique
Automobile is the main means of transport of modern society, and people are increasing for the demand of private car, quality and appearance
Requirement it is also higher and higher, this makes producer have to the research and development for accelerating new car.Most of part of automobile is all stamping parts, because
This Stamping Forming of Metal Sheets for Automobile technology becomes the key factor for restricting development of automobile.Compared with general stamping parts, automobile
Covering stock size is big, complex-shaped, molding difficulty is larger.Therefore, mold, design week are designed using traditional " trial-and-error method "
Phase is too long, and research and development cost is excessively high, has become the bottleneck of exploitation new model.With finite element technique and computer technology
Fast development, accurate Sheet metal forming analogue technique provide driving force for engineering design.The use of simulation software can
The reliability for improving planning process, effectively reduces die trial number and the die trial time of mold, improves the quality of design and mould of part
Press downtime when actual production and product rejection rate can be additionally greatly decreased in the design level of tool.Utilize software
Analog result instruct actual production, greatly reduce the production cost of product.Thin plate automobile panel drawing depth is shallower
In the case where, it is easy to appear large area drawing deficiency in drawing process, needs to be arranged two beads, also referred to as dual drawing
Muscle setting, and for space structure complexity, it distorts biggish sheet member and is locally being easy to appear rupture.This is because sheet member is easy
In rupture and the features such as drawing depth is shallower caused by.
Summary of the invention
The purpose of the present invention is to provide a kind of drawing die of automobile panel and determine bead and plate position
Method, solves that thin plate automobile panel drawing depth of the existing technology is shallower, the insufficient and thin plate that is easy to appear drawing
The problem of being easily broken.Formability of the present invention is good, while reducing plate size, has saved material, improves the benefit of material
With rate, production cost is reduced.Occur large area drawing deficiency drawing process suitable for thin plate automobile panel, needs to set
Two beads are set, also referred to as dual bead setting, and for space structure complexity, it is easy in part to distort biggish sheet member
In rupture the case where.
Above-mentioned purpose of the invention is achieved through the following technical solutions:
The drawing die of automobile panel, including cavity plate 1, punch-pin 4, plate 2, blank holder 3, the plate 2, blank holder 3 are located at
Between cavity plate 1 and punch-pin 4, cavity plate 1 is mounted on upper die holder, and on the lower die seat, plate 2 is located at recessed for blank holder 3 and the installation of punch-pin 4
Among mould 1 and blank holder 3, plate 2 is placed on blank holder 3；Cavity plate 1 and blank holder 3 drive plate 2 in movement in vertical direction,
Mandril on press bench passes through lower die holder and withstands blank holder 3 to provide the pressure-pad-force in drawing process, finally with it is convex
Mould molding.
The blank holder 3 and cavity plate 1 is equipped at least two draw-bead structures in binder surface two sides.
The draw-bead structure is inside bead 5 and outside bead 6, and is semicircle.
The distance between described inside bead 5 and outside bead 6 are 25 ~ 30mm, inside bead 5 and cavity plate circle
The distance between angle 7 is 25 ~ 30mm.
The distance between described inside bead 5 and outside bead 6 are 28mm, inside bead 5 and die entrance 7
The distance between be 28mm.
Another object of the present invention is to provide the method for a kind of determining bead and plate position, plate can be covered
Outermost draw-bead structure, and it is stamping after slab edge, that is, rewinding line receive to the outside of inside bead,
Rewinding line is obtained by numerical simulation method；Extend 40mm outward with conventional plate, and the guarantee of rewinding line covers
Outermost bead is different.Specific step is as follows:
Step 1: the movement of mold are as follows: cavity plate and blank holder compress plate first, then move downward, until punch-pin, cavity plate close
Mould；
Step 2: rewinding line should be located at the outside of inside bead, if rewinding line is more than inside bead, mold ginseng should be adjusted
Number, until eligible.
The beneficial effects of the present invention are: novel, structure is simple, using conveniently, safely.Effectively reduce sheet member
Drawing depth shallower the case where being easy to appear rupture, press formability is good, and reduces plate size, reduces and is produced into
This.It is practical.
Detailed description of the invention
