Abstract
The invention discloses a kind of car U-shaped beam class sheet metal component shaping methods, comprise the following steps：Step 1: by U-shaped beam opening downward, U-shaped beam is rotated to an angle a to side using the axis of U-shaped beam or center line as axle, making the bottom surface of U-shaped beam, the one side of that is, U-shaped beam is high side and another side is low side surface horizontal by non-parallel setting；Step 2: carrying out punching press shaping to U-shaped beam from vertical direction using mould, the high side of U-shaped beam uses positive shaping process, and the low side surface of U-shaped beam uses side shaping process.Positive shaping and side shaping is respectively adopted to the both sides of U-shaped beam in the present invention, the technological requirement of shaping can either be met, reduce Mold Making cost again, simplify the shaping process design of U-shaped beam class sheet metal component, debugging, operation is simple, can better ensure that workpiece quality of item.
Description
Technical field
The invention belongs to punching press shaping technique field, and in particular to a kind of car U-shaped beam class sheet metal component shaping methods.
Background technology
With the high speed development of present auto industry, people also require more and more higher to the quality of automobile, disappear to comply with
The demand of the person of expense, this requires to produce the higher sheet metal component of precision in automobile metal plate work production process.
Present U-shaped beam class shaping process is mainly completed using single positive shaping and side shaping.Due to U-shaped beam in itself
Shape, which determines, often walks moulding process, but easily resilience occurs and bad control after being molded, for the shaping process in later stage
There is higher requirement.Shaping process is also contemplated that springback compensation while shaping.
Usual technique is simple positive shaping or simple side shaping, and resilience amendment of the positive shaping for U-shaped beam is imitated
Fruit unobvious and state labile, and resilience amendment of the side shaping to U-shaped beam is more apparent, referring to figs. 1 to Fig. 3.But side is whole
The one side of Wedge mechanism 1 of shape can cause the increase of production cost, and another aspect is not easy to operate, technology stability is poor, so U-shaped
Beam brings very big puzzlement to each manufacturer.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can either meet that shaping requirement is beneficial to reduce mould system again
Make cost, simple and easy car U-shaped beam class sheet metal component shaping methods.
In order to solve the above technical problems, the technical scheme is that：Car U-shaped beam class sheet metal component shaping methods, including
Following steps：
Step 1: by U-shaped beam opening downward, U-shaped beam is rotated to side as axle using the axis of U-shaped beam or center line
Certain angle a, make the bottom surface of U-shaped beam horizontal by non-parallel setting, i.e., the one side of the U-shaped beam opposite side for high side
Face is low side surface；
Step 2: carrying out punching press shaping to U-shaped beam from vertical direction using mould, the high side of U-shaped beam uses positive shaping
Technique, the low side surface of U-shaped beam use side shaping process.
Preferably, after U-shaped beam anglec of rotation a, must ensure to meet following two conditions：
Condition one, U-shaped beam are using the side of positive shaping and the angle of at least 3 ° of pressing direction；
Condition two, U-shaped beam are not in negative angle when shaping is processed using the side of side shaping.
By adopting the above-described technical solution, compared with positive shaping simple in the prior art or side shaping process, this hair
It is bright to have the advantages that：Positive shaping and side shaping is respectively adopted in the both sides of U-shaped beam, can either meet that the technique of shaping will
Ask, ensure good Plastic renovation effect, and due to reducing the side shaping Wedge mechanism of side, also reduce Mold Making
Cost, simplify the shaping process design of U-shaped beam class sheet metal component, debugging, operation is simple, state of the art stability
It is good, workpiece quality of item can be better ensured that.
Brief description of the drawings
The following drawings is only intended to, in doing schematic illustration and explanation to the present invention, not delimit the scope of the invention.Wherein：
Fig. 1, Fig. 2 are the orientation schematic diagrames of U-shaped beam and pressing direction when using side shaping merely in the prior art；
Fig. 3 is state reference map when U-shaped beam uses merely side shaping in the prior art；
Fig. 4, Fig. 5 are the orientation schematic diagrames of U-shaped beam and pressing direction in the embodiment of the present invention；
Fig. 6 is state reference map when U-shaped beam both sides are respectively adopted positive shaping and side shaping in the embodiment of the present invention.
In figure：1- Wedge mechanisms；2-U type beams；21- is open；22- bottom surfaces；The high sides of 23-；24- low side surfaces.
Embodiment
With reference to the accompanying drawings and examples, the present invention is expanded on further.In the following detailed description, only explanation is passed through
Mode describes some one exemplary embodiments of the present invention.Undoubtedly, one of ordinary skill in the art will recognize,
In the case of without departing from the spirit and scope of the present invention, described embodiment can be repaiied with a variety of modes
Just.Therefore, accompanying drawing and description are inherently illustrative, are not intended to limit the scope of the claims.
Referring to figs. 1 to Fig. 3, in the prior art, U-shaped beam both sides use simple side shaping process, during shaping, U-shaped beam 2
Bottom surface 22 is set in parallel with horizontal plane S, and pressing direction A is vertical direction, and pressing direction A and U-shaped beam 2 phase of bottom surface 22 are hung down
Directly, two sides of U-shaped beam 2 carry out side shaping by Wedge mechanism 1 respectively.
With reference to figure 4 to Fig. 6, car U-shaped beam class sheet metal component shaping methods in the present invention, comprise the following steps：
Step 1: by the opening 21 of U-shaped beam 2 downward, using the axis of U-shaped beam 2 or center line as axle by U-shaped beam 2 to
Side rotates to an angle a (in the present embodiment by rotation 11 ° exemplified by), and bottom surface 22 and the horizontal plane S for making U-shaped beam 2 is in non-parallel
Set, that is, form following state：The one side of U-shaped beam 2 is high side 23 and another side is low side surface 24；
Step 2: punching press shaping (i.e. pressing direction A), the height of U-shaped beam 2 are carried out to U-shaped beam 2 from vertical direction using mould
Side 23 uses positive shaping process, and the low side surface 24 of U-shaped beam 2 uses side shaping process, and now, palpus guarantee meets following two
Condition：
Condition one, U-shaped beam 2 are at least 3 ° using the side (i.e. high side 23) of positive shaping and pressing direction A angle b；
Condition two, U-shaped beam 2 are not in negative angle when shaping is processed using the side of side shaping, are processed in the present embodiment
Angle is exemplified by 55 °.
So, by the way that positive shaping and side shaping is respectively adopted in the both sides of U-shaped beam, the technique that shaping can either be met
It is required that ensureing good Plastic renovation effect, and due to reducing the side shaping Wedge mechanism 1 of side, also reduce mould
Cost of manufacture, and simplify the shaping process design of U-shaped beam class sheet metal component, debugging, operation is simple, improves work
Skill stability, the quality of workpiece product can be better ensured that.
The schematical embodiment of the present invention is the foregoing is only, is not limited to the scope of the present invention.It is any
Those skilled in the art, made equivalent variations and modification on the premise of the design of the present invention and principle is not departed from,
The scope of protection of the invention should be belonged to.
