Abstract
A method for shaping the terminal end of transverse beam includes such steps as die drawing to make the terminal end of a beam have two lateral flanges and one upper flange, strimming, and cupring said upper flange.
Description
Technical field
The present invention relates to a kind of forming method of punching parts, more particularly, relate to a kind of forming method of termination of crossbeam workpiece.
Background technology
Sheet Metal Forming Technology is widely used in the auto manufacturing in recent years, and many coverings in the vehicle and inner plate all utilize mould to be stamped to form.Yet wherein, as shown in Figure 1, the end portion of some crossbeam workpiece need form flange 1 in the vehicle, wherein flange 1 comprises the upper flange limit 3 that is connected with the upper surface 2 of main body of cross-beam 10 and two side flange limits 5 that are connected with two side surfaces 4 of main body of cross-beam 10 respectively, angled respectively between upper flange limit 3 and the upper surface 2 and between side flange limit 5 and the side surface 4, and require to form certain gradient from side flange limit 5 to part 7, therefore the end portion of the such crossbeam workpiece very difficulty that is shaped along outward flange 6 transition of main body of cross-beam 10 length directions.
For the moulding problem of this type of part, adopt the method for the skill breach that on part, goes into operation to solve in the prior art usually, as shown in Figure 2.This method be part finish draw after, utilize to have tangent mechanism and add the mould that hangs cutting mechanism and on part, open four technology breach 8, and then utilize flanging die that part is carried out to upper overturning and side flanging respectively, thereby form required flange.
Yet this method that goes into operation the skill breach not only makes the structure of mould become very complicated, and needs the many groups of design mould, so just makes manufacturing cost increase, the processing technology complexity, and production efficiency reduces.Simultaneously because the technology breach on the part can exert an influence to part integral intensity, rigidity, if even and indentation, there have very small crackle, also can form stress and concentrate, therefore will be, even the security of vehicle integral body brings hidden danger to whole part.
Summary of the invention
The purpose of this invention is to provide a kind of forming method that can reduce production costs, simplify the crossbeam workpiece termination of processing step, reduction technology difficulty and good forming effect.
The forming method of the termination of crossbeam workpiece provided by the invention comprises: product is drawn into beam shape, the termination of the product after wherein drawing comprise be connected with two side surfaces of main body of cross-beam respectively and with side surface not on conplane side flange limit and the upper flange limit that is connected with the upper surface of main body of cross-beam; Then product is carried out deburring; At last flange is carried out on the upper flange limit.
The forming method of the termination of crossbeam workpiece provided by the invention, not only do not need many group moulds, simplified processing step, reduced technology difficulty, simultaneously owing to avoided the skill breach that on part, goes into operation, therefore can not exert an influence, and eliminate the stress that causes because of the crackle on the technology breach and concentrated the potential safety hazard of bringing part integral intensity and rigidity.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
The forming method of the termination of crossbeam workpiece provided by the invention comprises product drawn into beam shape, the termination of the product after wherein drawing comprise be connected with two side surfaces 4 of main body of cross-beam 10 respectively and with side surface 4 not on conplane side flange limit 5 and the upper flange limit 3 ' that is connected with the upper surface 2 of main body of cross-beam 10; Then product is carried out deburring; At last flange is carried out on upper flange limit 3 '.
Under the preferable case, the termination of drawing into the product of beam shape comprises box-like part 9, described box-like part 9 comprise be connected with two side surfaces 4 of main body of cross-beam 10 respectively and with side surface 4 not on conplane side flange limit 5 and the upper flange limit 3 ' that is connected with the upper surface 2 of main body of cross-beam 10.
Under the preferable case, described side flange limit 5 is vertical mutually with side surface 4.Described upper flange limit 3 ' and upper surface 2 are in same plane.And, when flange is carried out on upper flange limit 3 ' or afterwards shaping is carried out in the termination.
When utilizing the termination of this kind optimal way forming cross-beam class part, at first, product is drawn into needed beam shape, and the termination of product draws and replenish to form box-like part 9, as shown in Figure 3.Wherein on described box-like part 9 and upper surface that main body of cross-beam 10 links to each other, comprise the upper flange limit 3 ' of required formation, and the upper surface 2 of upper flange limit 3 ' and main body of cross-beam 10 is in same plane.On described box-like part 9 and side that main body of cross-beam 10 links to each other, except the part that connects with main body of cross-beam 10, remaining is arranged in two side flange limits 5 that comprise required formation along the part of main body of cross-beam 10 both sides of main body of cross-beam 10 widths.Between the side surface 4 of side flange limit 5 and main body of cross-beam 10 and and comprise that shape has a certain degree between the flat board 11 of outward flange 6, this angle can be decided according to the shape of the flange of the termination of required formation.The part that box-like part 9 is connected with main body of cross-beam 10 forms needed transition cambered surface, and the part that this side of box-like part 9 is connected with the flat board 11 that comprises outward flange 6 forms needed transition cambered surface.The degree of crook of the degree of crook of the fillet surface part that the size and dimension of described box-like part 9, box-like part 9 are connected with main body of cross-beam 10 and the fillet surface part that box-like part 9 is connected with the flat board 11 that comprises outward flange 6, can determine according to the size and the shape of the flange of the termination of required formation, to be suitable for the requirement of different crossbeam workpieces.
Then, can utilize Trimming Die that the product after drawing is carried out deburring as required, the redundance of product is removed, the product shape after the deburring as shown in Figure 4.Wherein, how much the position of deburring and deburring amount can decide according to the concrete shape need of part.
At last, upper flange limit 3 ' is carried out to upper overturning.In addition,, and using drawing work product to be carried out in the process of moulding,, needing little fillet is amplified, in follow-up operation, be trimmed to required shape again in order to allow material successfully flow because the desired fillet of actual part is generally all smaller.Therefore, when carrying out flange or also need afterwards shaping is carried out in the termination, so that product forms final needed shape, as shown in Figure 5.
