Description
Technical field
The invention belongs to Sheet Metal Forming Technology technical field, particularly relates to a kind of MPV vehicles cross-beam connecting plate punch forming process
And the Trimming Die for being used.
Background technology
Body of a motor car accounts for the 30% of automobile gross weight, and under no-load condition, about 75% oil consumption is used on body quality.Gently
Quantization is the effective way for reducing automobile fuel consumption, reducing discharge, improve vehicle fuel economy.The use of high-strength steel is vapour
The important channel of car body lightening, and high-strength steel is during punch forming, is to limit which the problems such as distortion caused by resilience
One key factor of quality.Good moulding process can effective control resilience, it is ensured that stamping parts quality.
As depicted in figs. 1 and 2, it is MPV vehicle cross-beam connecting plate schematic diagrames, in vehicle body, this stamping parts is with vehicle body axis
Symmetrical, Fig. 1 and Fig. 2 show the 3rd beam left connecting plate, and right side part is the 3rd crossbeam right connection board, the spy of the stamping parts
Point is that have a perforate 01 in the middle of stamping parts, has flange in this stamping parts both sides.
Traditional forming method is as shown in figure 3, comprise the following steps:
1) blanking, i.e., carry out blanking comprising middle perforate along stamping parts material sideline;
2) it is molded, plate that will be after blanking carries out flange by mould molding;
3) punching, i.e., four apertures of flat die on the stamping parts of shaping.
This technique has perforate because of stamping parts middle setting, therefore, in forming process, plate flowing is wayward, into
After type, stamping parts distortion is serious, and stability is poor.
If the perforate in the middle of most backlash, ordinary circumstance need side to repair, waste material is discharged and is difficult to, and mould structure is complicated,
Such as adopt and just repair, it is also desirable to solve the problems, such as punching press negative angle.
The content of the invention
It is an object of the invention to provide a kind of MPV vehicles cross-beam connecting plate punch forming process and Trimming Die, to solve
Stamping parts distortion is serious, the problem of stability difference;
Another object of the present invention is that to solve, waste material is difficult to discharge and punching press negative angle is difficult to by optimizing mould structure
The problem of solution.
The present invention is achieved by the following technical solutions:
A kind of MPV vehicles cross-beam connecting plate punch forming process, comprises the following steps:
1) blanking, rushes main location hole and auxiliary location hole first on bar shaped plate, and carries out blanking along blank line;
2) it is molded, by the blank after blanking by mould molding, while the shaping flange of two sides is realized, two sides
The shaping flange of the side flanging of the front end of the shaping flange and two sides of the lower flange of bottom, is obtained crude green body material
3) first time deburring and punching, the crude green body material upper plane along setting central aperture on described plane
The upper trimming line that position is formed carries out the hole of first time deburring and punching press on described in plane;
4) second deburring, in step 3) after, the left side formed on the left side along the central aperture of the setting is repaiied
Sideline carries out second deburring;
5) third time deburring, in step 4) after, the right side formed in the right edge along the central aperture of the setting is repaiied
Sideline carries out third time deburring;
6) in step 5) after, the stamping parts after deburring is carried out whole.
The location hole is circular port, and the auxiliary location hole is irregularly-shaped hole.
The auxiliary location hole is mounting hole.
A kind of Trimming Die for any of the above-described, including lower template, location-plate, lower die cutter block, upper die plate, binder
Plate, upper mould cutter block and upper die plate;
The lower die cutter block is installed in the lower template, and the location-plate is arranged on the lower die cutter block;
The upper die plate is fixed on the upper die plate, and the upper mould cutter block is fixed on the upper die plate, described
Holding pad is elastic connection with the upper die plate;
The lower die cutter block includes lower-left mould cutter block and bottom right mould cutter block, the lower-left mould cutter block and the bottom right mould cutter block
Center line along the holding pad is symmetrical;
The upper face of the upper face and bottom right mould cutter block of the lower-left mould cutter block has the folder more than 0 degree with horizontal plane
Angle.
The angle is 5 degree.
The invention has the beneficial effects as follows:
The technical program by optimizing moulding process, in blanking operation, former technique blanking first by the outline of blank and
Middle perforate is dropped out and, and the modified technique of the technical program is only to drop out by the outline of blank in blanking operation,
The perforate of centre is not rushed, and increases by two location holes of punching in advance, for playing positioning action, to avoid plate in forming process
Play.
In the technical program, two location hole techniques are increased, the perforate of centre is not first processed in sheet metal forming, is made
Plate in forming process with die face uniform contact, bigger relative to former process contact face, the flowing of plate can be led to
Cross mould preferably to control.
In the technical program, by the central aperture that falls of former technique, after the action of four apertures of punching is adjusted to improve
Three trimming process steps in, it is therefore an objective to can better control in forming process because shaping after there is deburring angle problem,
Three operation deburrings are improved to by an operation blanking, although increased number of molds, but the quality of shaped article has larger
Improve.
The technical program increases trimming, carries out shaping to two sides flange position, further improves precision of stamping parts.
