Abstract

The present invention discloses a kind of technique of control tailgate outside plate lower section turning rebound, and concrete technology is the following steps are included: Step 1: carry out drawing to automobile back door plate using drawing die;Step 2: the control of drawing face drafting angle is crossed at 4-5 °, close to pre- flange face by corner in drawing process;Step 3: carrying out shaping to the automobile back door plate after drawing.Such technique can effectively control the rebound after parts flanged-edge shaping, reduce later period debugging difficulty.Tailgate outside plate lower section is since product-forming is relatively easy, using this new process, can guarantee that drawing is abundant, meet the requirement of outer covering piece, corner's flange belongs to compressibility flange, and wire length can shorten, after external force removal, stress release, so that the face product A region be driven to spring back;This technique reduces flange amount, the rebound after enabling flange is controlled in 1mm or so, then by metal plate, be can satisfy trial-production and required by changing drawing form.

Description

A kind of technique of control tailgate outside plate lower section turning rebound
Technical field
The present invention relates to a kind of techniques of control tailgate outside plate lower section turning rebound, are related to automobile part production technique neck Domain.
Background technique
Automobile panel exterior panel is in automotive-type part to product surface quality, forming adequacy and dimension precision requirement Higher, by taking door skin part as an example, stamping process mainly includes blanking, drawing, twice trimming, flange, lateral flange etc., Wherein drawing operation is the forming process of door skin principal shape feature, at this stage the most of auto parts and components production in China Work, the especially production of trial-production mould and manufacture work, are widely used that cold punching technology technique.In cold punching technology Manufactured components will appear the situation of rebound often, there is more serious mass defect, when examination part forming die forms simultaneously And after opening, the shape of part will appear variation, inconsistent, the such situation pair with the form of original mold in closed condition It is tremendous influence for the components production of automobile, when rebound value is more than certain range, not only results in vehicle body Specification qualification rate reduces, while influencing whether the matching state of components and vehicle.This technology is returned for exterior panel turning Bullet proposes a solution.
Summary of the invention
The purpose of the present invention is to provide a kind of techniques of control tailgate outside plate lower section turning rebound, to solve above-mentioned background The problem of being proposed in technology.
To achieve the above object, the present invention provides the following technical solutions a kind of work of control tailgate outside plate lower section turning rebound Skill is the following steps are included: Step 1: carry out drawing to automobile back door plate using drawing die;
Step 2: the control of drawing face drafting angle is crossed at 4-5 °, close to pre- flange face by corner in drawing process;
Step 3: carrying out shaping to the automobile back door plate after drawing.
Preferably, the setting of drawing face drafting angle is to carry out analysis and regulation according to CAE in the step two.
Preferably, the springback control after automobile back door plate flange is in 1mm in the step 2 after drawing.
Compared with prior art, the beneficial effects of the present invention are: such technique can effectively control parts flanged-edge shaping it Rebound afterwards reduces later period debugging difficulty.Tailgate outside plate lower section is since product-forming is relatively easy, using this new process, It can guarantee that drawing is abundant, meet the requirement of outer covering piece, corner's flange belongs to compressibility flange, and wire length can shorten, when outer After power removal, stress release, so that the face product A region be driven to spring back;This technique reduces flange by changing drawing form Amount, the rebound after enabling flange are controlled in 1mm or so, then by metal plate, be can satisfy trial-production and required.
Detailed description of the invention
Fig. 1 is certain vehicle automobile back-door outer panel lower section structural schematic diagram in embodiment;
Fig. 2 is traditional scheme and this programme drawing work comparison diagram.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Embodiment: Fig. 1 is certain vehicle automobile back-door outer panel lower section, the work sprung back using this control tailgate outside plate lower section turning Skill carries out drawing to automobile back door plate;The control of drawing face drafting angle is crossed at 4 °, close to pre- flange by corner in drawing process Face carries out shaping to the automobile back door plate after drawing.
The setting of drawing face drafting angle is to carry out analysis and regulation according to CAE in the present embodiment;
After the present embodiment drawing, the springback control after automobile back door plate flange is in 1mm.
Fig. 2 is traditional scheme and this programme drawing work comparison diagram, and drafting angle control in drawing face subtracts at 4 ° in this technique Small flange amount made drawing draft face be positioned as close to pre- flange face.
As seen from Figure 1, it advantage of this embodiment is that the rebound after parts flanged-edge can be controlled effectively, reduces Later period debugging difficulty reduces mould development cost.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
