Description
1, technical field:
The present invention is a kind of sheet metal hydroforming method and die device thereof, belongs to sheet metal hydroforming method and die device innovative technology thereof.
2, background technology:
Conventional rigid is protruding, be recessed into the shape mould, when the part of shaping automobile panel, motorcycle tank shell and so on, because such part has reducing, the rigidity punch can not enter die, thereby can't Integratively be shaped, have to adopt two molds, after being separated into left and right two lobes, integral tank is formed separately, cut edge afterwards, again welding.The shortcoming of its existence is that not only the forming technology step number is many, mould and welder complexity, welding process requirement height, and the danger of the hiding leakage of oil of breaking of weld when motorcycle overturns.
3, summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming and but a kind of sheet metal hydraulic forming mold device of simple in structure, the few Integratively forming belt of forming technology step number reducing part is provided.The present invention can significantly reduce production costs, improve the quality of products, strengthen the new product development in enterprises ability, create remarkable economic efficiency, the difficult shaping new material sheet parts such as aluminium alloy, magnesium alloy, titanium alloy and high strength steel that can be used for being shaped can be used for the thin-sheet metal part forming processing complex-shaped, that deflection is big.
The hydroforming method of sheet metal of the present invention comprises the steps:
1) earlier hydraulic pressure chamber (8) is full of hydraulic oil;
2) plate to be formed (3) is placed between hydraulic pressure chamber (8) and the die (2);
3) die (2) is descending;
4) plate (3) and die (2) are applied flanging and clamp force F;
5) pressurising power is the high pressure liquid of P, makes plate deep-drawing deformation under the effect of high pressure liquid, is close to the shape that the concave die cavity shaping surface is required part.
The structural representation of sheet metal hydraulic forming mold device of the present invention as shown in drawings, include cope match-plate pattern (1), die (2), hydraulic plate (5), make the concave die cavity consistent (9) on the die (2) with part shape to be formed, made hydraulic pressure chamber (8) on the hydraulic plate (5), plate (3) places between cope match-plate pattern (1) and the hydraulic plate (5).
Also be provided with sealing ring (4) between above-mentioned cope match-plate pattern (1) and the hydraulic plate (5).
Made steam vent (10) on the above-mentioned die (2).
Make the fuel feed hole (7) that communicates with hydraulic pressure chamber (8) on the above-mentioned hydraulic plate (5).
Above-mentioned die (2) include can about the edge body die (2a, 2b) that separates.
Above-mentioned hydraulic plate (5) can be installed on the lower bolster (6).
Above-mentioned hydraulic plate (5) can be made of one with lower bolster (6).
The present invention is owing to adopt liquid medium to substitute traditional punch, the band reducing part protruding with conventional rigid, that die can't be shaped and can be used for the thin-sheet metal part forming complex-shaped, that deflection is big and process so can be used for being shaped is as the processing of automobile panel, motorcycle tank shell etc.; But the few Integratively forming belt of the hydroforming method technology step number reducing part of sheet metal of the present invention can significantly reduce production costs, and improves the quality of products, and strengthens the new product development in enterprises ability, creates remarkable economic efficiency.The hydraulic forming mold device design of sheet metal of the present invention is ingenious, simple in structure, convenient and practical.
