Description

Two-side flanging stamping mechanism for automobile parts

Technical Field

The utility model relates to an auto-parts punching press field of making, in particular to auto-parts's both sides hem punching press mechanism.

Background

In the automobile parts, including supporting parts, connecting parts or structural parts and the like, generally need to be punched and manufactured, particularly some structural parts, due to the design and specific use requirements, the flanging operation needs to be carried out on the structural parts, and the flanging shapes can be used for improving the structural strength, improving the elasticity and the shock absorption capacity or reducing the weight and materials of a body.

Disclosure of Invention

An object of the utility model is to provide an auto-parts's both sides hem punching press mechanism to solve prior art when the preparation, production efficiency is low, the product quality is poor technical problem.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the utility model provides an auto-parts's both sides hem punching press mechanism, is including corresponding last mould and the lower mould that sets up, the lower mould is fixed on the base station, the lower extreme both sides of lower mould are equipped with inward dead slot, the both sides of lower mould dead slot all correspond and are provided with the side form, the dead slot and the side form of lower mould are configured to be used for punching press out the arc hem and are modelled, it all is connected with the punching press arm to go up mould and side form, the punching press arm can drive and go up mould vertical direction displacement from top to bottom, displacement about the drive side form horizontal direction.

Further, the lower extreme outside of lower mould is equipped with the arc chamfer, the side form also corresponds and is provided with the arc chamfer. The stamping quality of the folded edge is improved, and the possibility of cracking of the material in the stamping process is reduced.

Furthermore, a discharging push rod is arranged on one side of the lower die, and a driving part is arranged at one end of the discharging push rod. The finished product is conveniently pushed out along the direction of the lower die, and the automation level and the generation efficiency are improved.

After this scheme of adoption, contrast prior art has following beneficial benefit:

the utility model can punch the single sheet material into the structural member with the two-side flanging modeling, does not need complex multi-platform multiple punching operation, has high product flatness, and greatly improves the product quality and the yield;

when the mechanism is manufactured, the mechanism parts with the folded edges at two sides can be quickly formed through the stamping mechanism, the generation efficiency is greatly improved, the labor cost is reduced, and technical support is provided for high-speed assembly line production.

Detailed Description

In order to manufacture the automotive accessory two-side folded edge structural member 1 shown in fig. 1, the structural member 1 comprises a body of a C-shaped structure and reinforcing parts 11 folded towards the inner circle at two ends of the body, the reinforcing parts 11 can improve the strength and the service life of the structural member, the possibility of bending or cracking of the structural member can be reduced when a vehicle receives impact force through the reinforcing parts 11, metal materials are saved under the condition of the same strength, the weight is reduced, and the load of the vehicle is reduced.

Referring to fig. 1, a press mechanism for flanging two sides of an automobile accessory comprises an upper die 2 and a lower die 3 which are correspondingly arranged, wherein the lower end of the lower die 3 is fixed on a base station 5, inward empty grooves are formed in two sides of the lower end of the lower die 3, namely, an arc-shaped part 31 for punch forming is arranged at the top of the empty groove of the lower die 3, the arc-shaped part 31 is provided with a 90-degree arc-shaped chamfer, two sides of the arc-shaped part 31 are correspondingly provided with side dies 4, the side dies 4 are also correspondingly provided with arc-shaped chamfers, and the arc-shaped chamfers of the side dies 4 and the arc-shaped chamfers of the arc-shaped; the upper die 2 is connected with a stamping arm 21 and a stamping power source, the stamping arm 21 and the stamping power source can drive the upper die 2 to move up and down in the vertical direction, the side die 4 is connected with a stamping arm 41 and a stamping power source, the stamping arm 41 and the stamping power source can drive the side die 4 to move left and right in the horizontal direction, and the operation that the side dies 4 on two sides horizontally converge or diverge towards the lower die 3 is realized.

Be equipped with ejection of compact push rod 51 in lower mould 3 front side, ejection of compact push rod 51's one end is connected with cylinder 52, and under cylinder 52's effect, ejection of compact push rod 51 can be along lower mould 3 side level reciprocating motion around to can release 1 finished products of structure on lower mould 3, improve automatic level and generation efficiency, also reduced the injury risk that the manual work probably exists when the ejection of compact.

Referring to fig. 3, in the manufacturing process, in order to manufacture the structural member 1 with two side edges folded as shown in fig. 1, firstly, the cut and flat material is conveyed to the upper part of the lower die 3, the upper die 2 is displaced downwards under the action of the stamping arm 21 and the stamping power source, and the material is stamped into a C-shaped structure in the process of contacting with the lower die 3, and then the upper die 2 continues to keep the current position, and the side dies 4 on two sides are horizontally converged and displaced from the two sides to the lower die 3 under the action of the stamping arm 41 and the stamping power source and are contacted with the arc-shaped part 31 of the lower die 3, so that the material of the reinforcing part 11 is stamped into the shape of the arc-shaped edges on two sides;

the rear side die 4 is respectively separated towards two sides, the upper die 2 moves upwards, at the moment, the structural part 1 is separated from the side die 4 and the upper die 2 and covers the outer edge of the lower die 3, the discharging push rod 51 pushes the structural part 1 to be pushed out from one side of the lower die 3 under the action of the air cylinder 52, and a finished product of the structural part 1 is obtained from one side of the lower die 3;

by circulating the operation, the automobile parts of the two-side folded edge structural part can be continuously and efficiently manufactured through the two-side folded edge stamping mechanism of the automobile parts.
