Abstract
The present invention relates to a press-forming process of strip metal. Said process includes the following steps: (1), placing the workpiece to be machined on the mutually-spaced front and rear lower modules; (2), making the front upper module be tightly pressed on the workpiece positioned in one side of forming zone; (3), making the rear upper module be pressed on the workpiece positioned in another side of forming zone, and applying preload capable of making material be flowed on rear upper module; (4), making ram head female die be quickly downwards moved and pressed on the workpiece to be machined between front and rear upper modules to make it envelope male die so as to form semi-finished product; and (5) utilizing cutting die to cut edge of said semi-finished product and obtain the required product.
Description
Technical field
The present invention relates to a kind of processing technology of metal forming, specifically refer to a kind of punch forming process of bullion.
Background technology
At present, the bullion punch forming process is after the organizing work of calculated in advance allowance, blank, and blanking becomes workpiece to be processed, then workpiece to be processed is placed on the lower module, and the non-forming area of workpiece to be processed is gripped; Then the upper module drift is moved down rapidly, make the workpiece to be processed envelope on lower module, finally after cutting edge, make required profile.But find in practice: because the non-forming area of workpiece to be processed is held tight; that is to say; workpiece to be processed can't move along all directions; therefore be subjected to the influence of factors such as diel precision, surface roughness bigger by the prepared formed product face of above-mentioned technology; usually can cause that wrinkle appears in the formed product surface, defective such as atomize, break; and this class defective is if appear on the automobile bar shaped annex, especially never allows appearing on the automobile bar shaped decoration.So the profile after the above-mentioned punch forming also usually needs technologies such as polishing, deburring to repair.Obviously, such method both influenced forming surface quality, improved the cost of manufacture of product again.Particularly along with the development of car industry, the surface texture of all kinds of bullion decorations emerges in an endless stream, and form is different, and is also more and more higher to the quality requirement on surface, also just become the current technical issues that need to address so how to improve the forming surface quality.
Summary of the invention
Technical problem to be solved by this invention is the present situation at prior art, and a kind of surface quality that can guarantee profile is provided, and can make the punch forming process of the bullion that processing step is simple, cost is low again.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
1. workpiece to be processed is placed on the forward and backward lower module of mutual separation;
2. relative with preceding lower module corresponding preceding upper module is compressed on the workpiece to be processed of forming area one side, and the workpiece to be processed of this side is compressed;
3. be compressed on the workpiece to be processed of forming area opposite side with the corresponding back of lower module, back upper module, and on the upper module of back, apply the preload that material is flowed;
4. after the drift die moves down rapidly, be pressed on the workpiece to be processed between the forward and backward upper module, the forming area envelope that makes workpiece to be processed is outside punch and form semi-finished product;
5. above-mentioned semi-finished product obtain required product after with the blanking die cutting edge.
The fore-end of lower module can be designed to described punch and make both parts that becomes one before described.
Distance between the described forward and backward upper module can be the effective length of the forming area of workpiece to be processed, and The mould features compact structure so more can be guaranteed the quality of forming surface.
Compared with prior art, because the present invention does not press tight at the workpiece to be processed opposite side, but apply preload as required, like this in the folding process of drift die, make the forming area both sides all be subjected to tractive force, make the metal flow of opposite side simultaneously, and this amount of flow can be controlled by the preload that applies, therefore the present invention needn't calculate before moulding because of material extending, the allowance that compression is caused, also needn't carry out organizing work of blank, also need not to carry out the deburring after prior blanking and the cutting edge, so simplified processing technology widely, cost of manufacture is low like this, can control the amount of flow of material again, thereby has prevented wrinkle in the forming process effectively, atomizing and generation of defects such as break.

Fig. 3 is the finished product structure chart after the embodiment of the invention punch forming.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the punch forming process of this bullion adopts following procedure of processing: 1. workpiece to be processed 1 is placed on the preceding lower module 2 and back lower module 3 of mutual separation, here, before the fore-end design of lower module in punch 21 structures, the forming area of workpiece to be processed 1 is over against should punch; 2. be compressed on the workpiece to be processed of forming area one side with preceding lower module 2 relative corresponding preceding upper modules 4, the rear end part of lower module 2 before promptly being pressed in, and the workpiece to be processed of this side compressed, limit the free degree of this side workpiece to be processed, to prevent its moving in forming process; 3. after moving down with back lower module 3 corresponding back upper modules 5, be compressed on the workpiece to be processed of forming area opposite side, and on the upper module 5 of back, apply the preload that material is flowed.Here, the distance between the forward and backward upper module is the effective length of the forming area of workpiece to be processed.And the application of force size of preload be need according to the effective area of forming area, metal material thickness, material behavior, drawing depth and in actual forming process factor such as formed product quality determine.Under same material, identical drawing depth condition, when preload hour, the amount of flow of material is big, wrinkling aggravation; And preload is when big, and the amount of flow of material is little, can cause the drawing crack of forming surface.Therefore, from practical operation as can be known: under different materials and different specification requirement, apply different preloads, just can control the amount of flow of material as required, thereby can be controlled to the quality of profile easily.In the present embodiment, be 0.4mm at material thickness, drawing depth is 5.5mm, the effective area that is compressed on the forming area opposite side is 1080mm
2The time, the preload that is applied is 800N, just can obtain forming surface preferably.4. after drift die 6 moves down rapidly, be pressed on the workpiece to be processed between the forward and backward upper module, the forming area envelope that makes workpiece to be processed is on the punch of front module front end and form as shown in Figure 2 semi-finished product 1a; 5. above-mentioned semi-finished product are obtained required product 1b after with the blanking die cutting edge, as shown in Figure 3.
