Abstract
The invention discloses a kind of car U-shaped beam class sheet metal component shaping methods, include the following steps: Step 1: downward by U-shaped beam opening, U-shaped beam is rotated by a certain angle a to side using the axis of U-shaped beam or center line as axis, make the bottom surface of U-shaped beam horizontal by non-parallel setting, i.e., the one side of U-shaped beam is high side and another side is low side surface；Step 2: carrying out punching press shaping to U-shaped beam from vertical direction using mold, 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 two sides of U-shaped beam in the present invention, the technique requirement of shaping can either be met, and reduce Mold Making cost, simplify the shaping process design scheme 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 fields, and in particular to a kind of car U-shaped beam class sheet metal component shaping methods.
Background technique
With the high speed development of present auto industry, people also require the quality of automobile higher and higher, disappear to comply with
The demand of the person of expense, this requires the higher sheet metal component of precision is produced 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 itself
Shape, which determines, often walks moulding process, but rebound is easy to appear after forming and bad control, for the shaping process in later period
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 positive shaping corrects effect for the rebound of U-shaped beam
Fruit is unobvious and state labile, and side shaping is more apparent to the rebound amendment of U-shaped beam, referring to figs. 1 to Fig. 3.But side is whole
1 one side of wedge mechanism of shape will 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.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can either meet shaping requirement, is conducive to reduce mold 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: downward by U-shaped beam opening, U-shaped beam is rotated to side using the axis of U-shaped beam or center line as axis
Certain angle a makes the bottom surface of U-shaped beam horizontal by non-parallel setting, i.e., the one side of U-shaped beam other side for high side
Face is low side surface；
Step 2: carrying out punching press shaping to U-shaped beam from vertical direction using mold, the high side of U-shaped beam uses positive shaping
The low side surface of technique, U-shaped beam uses side shaping process.
Preferably, must guarantee to meet following two condition after U-shaped beam rotates angle a:
The side and at least 3 ° of pressing direction of angle of condition one, U-shaped beam using positive shaping；
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
Positive shaping and side shaping is respectively adopted in the bright two sides for having the advantages that U-shaped beam, and the technique that can either meet shaping is wanted
It asks, guarantees good Plastic renovation effect, and the side shaping wedge mechanism due to reducing side, also reduce Mold Making
Cost simplifies the shaping process design scheme of U-shaped beam class sheet metal component, and debugging, operation is simple, state of the art stability
It is good, it can better ensure that workpiece quality of item.
Detailed description of the invention
The following drawings are only intended to schematically illustrate and explain 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 two sides are respectively adopted positive shaping and side shaping in the embodiment of the present invention.
In figure: 1- wedge mechanism；2-U type beam；21- opening；The bottom surface 22-；The side 23- high；24- low side surface.
Specific embodiment
With reference to the accompanying drawings and examples, the present invention is further explained.In the following detailed description, only pass through explanation
Mode describes certain exemplary embodiments of the invention.Undoubtedly, those skilled in the art will recognize, In
In the case where without departing from the spirit and scope of the present invention, described embodiment can be repaired with a variety of different modes
Just.Therefore, attached drawing and description are regarded as illustrative in nature, and are not intended to limit the scope of the claims.
Referring to figs. 1 to Fig. 3, in the prior art, U-shaped beam two sides use simple side shaping process, when 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 22 phase of bottom surface of U-shaped beam 2 are hung down
Directly, two sides of U-shaped beam 2 pass through the progress side shaping of wedge mechanism 1 respectively.
With reference to fig. 4 to fig. 6, car U-shaped beam class sheet metal component shaping methods in the present invention include the following steps:
Step 1: downward by the opening 21 of U-shaped beam 2, using the axis of U-shaped beam 2 or center line as axis by U-shaped beam 2 to
Side rotates by a certain angle a (in the present embodiment by taking 11 ° of rotation as an example), makes the bottom surface 22 of U-shaped beam 2 with horizontal plane S in non-parallel
Setting, 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) is carried out to U-shaped beam 2 from vertical direction using mold, the height of U-shaped beam 2
Side 23 uses positive shaping process, and the low side surface 24 of U-shaped beam 2 uses side shaping process, at this point, must guarantee to meet 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 the angle b of pressing direction A；
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 for 55 °.
So, by the way that positive shaping and side shaping is respectively adopted in the two sides of U-shaped beam, the technique that shaping can either be met
It is required that guaranteeing good Plastic renovation effect, and the side shaping wedge mechanism 1 due to reducing side, mold is also reduced
Cost of manufacture, and simplify the shaping process design scheme of U-shaped beam class sheet metal component, debugging, operation is simple, improves work
Skill stability can better ensure that the quality of workpiece product.
The foregoing is merely the schematical specific embodiment of the present invention, the range being not intended to limit the invention.It is any
Those skilled in the art, made equivalent changes and modifications under the premise of not departing from design and the principle of the present invention,
It should belong to the scope of protection of the invention.
