Abstract
The invention provides a forming method for front and rear aluminium alloy bumper brackets, and aims to overcome the shortcomings of conventional front and rear aluminium alloy bumper brackets of cars. The forming method comprises the following steps: (1) front and rear aluminium alloy bumper bracket parts are placed on a supporting plate with a guide plate; (2) before bending of the front and rear aluminium alloy bumper bracket parts, an anti-sink core rod is pushed into the front and rear aluminium alloy bumper support parts through a cylinder; (3) when an upper die is depressed into the front and rear aluminium alloy bumper bracket parts, a damping mechanism is cut into the front and rear aluminium alloy bumper bracket parts; and (4) when the front and rear aluminium alloy bumper bracket parts are bent by a die, the anti-sink core rod and a crease-resistant extending mechanism are used for acting on the front and rear aluminium alloy bumper bracket parts. The forming die solves the problems that when an aluminum profile shaped like two squares stacked vertically is bent, the outer wall sinks, the inner wall is corrugated and the side wall protrudes.
Description
Technical field
The present invention relates to the bumper field shaping technique, specifically, relate to the forming method of a kind of aluminium alloy front and back bumper holder.
Background technology
Aluminium alloy is a most widely used class non-ferrous metal structural material in the industry, aluminium alloy density is low, but strength ratio is higher, approach or surpass the high-quality steel, plasticity is good, can be processed into various section bars, has good electric conductivity, thermal conductivity and corrosion stability, widely apply in Aeronautics and Astronautics, automobile, machine-building, boats and ships and chemical industry, its use amount is only second to steel.
The material of bumper applications is steel in the at present general car, and adopt the bumper of aluminium section bar lighter than the weight of steel, and energy-absorbing effect is better, therefore adopting aluminium alloy to make the front and back bumper, directly in the application of research aluminium section bar, one of difficult point is its moulding process, through to market and investigation of the same trade, also rarely has the forming method of aluminium alloy front and back bumper holder.
Summary of the invention
The present invention be directed to have now and adopt aluminium alloy to make the deficiency that car front and back bumper holder exists, the forming method of a kind of aluminium alloy front and back bumper holder is provided.
The technical problem that will solve required for the present invention can be achieved through the following technical solutions:
The forming method of bumper holder is characterized in that before and after a kind of aluminium alloy, comprises the steps:
1) bumper holder part before and after the aluminium alloy is placed on the supporting plate that has guide plate;
2) before and after aluminium alloy, before the bumper holder spares bend, with cylinder the anti-depression plug is pushed aluminium alloy front and back bumper holder part earlier;
3) before and after being pressed downwardly onto aluminium alloy, patrix in the bumper holder part, uses to have damping mechanism incision aluminium alloy front and back bumper holder part;
4) before and after the crooked aluminium alloy of mould, in the bumper holder part, use anti-depression plug and the wrinkle resistant mechanism of drawing to act on alloy front and back bumper holder part.
The forming method of bumper holder utilizes the bend pipe forming principle before and after the aluminium alloy of the present invention, increase plug at mould structure and prevent the outer wall depression, bumper holder part side is provided with and puts prominent plate before and after the aluminium alloy, inwall be provided with draw structure prevent wrinkling, solved a day font aluminium section bar when bending the outer wall depression, inwall is wrinkling and the problem of sidewall projection.
The specific embodiment
In order to make technological means of the present invention, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Purport of the present invention is, solves to have now and adopts aluminium alloy to make the deficiency that car front and back bumper holder exists, and the forming method of a kind of aluminium alloy front and back bumper holder is provided.
The forming method of bumper holder before and after the aluminium alloy of the present invention adopts following steps: 1) bumper holder part before and after the aluminium alloy is placed on the supporting plate that has guide plate; 2) before and after aluminium alloy, before the bumper holder spares bend, with cylinder the anti-depression plug is pushed aluminium alloy front and back bumper holder part earlier; 3) before and after being pressed downwardly onto aluminium alloy, patrix in the bumper holder part, uses to have damping mechanism incision aluminium alloy front and back bumper holder part; 4) before and after the crooked aluminium alloy of mould, in the bumper holder part, use anti-depression plug and the wrinkle resistant mechanism of drawing to act on alloy front and back bumper holder part.
Like this, increase plug at mould structure and prevent the outer wall depression, bumper holder part side is provided with and puts prominent plate before and after the aluminium alloy, inwall be provided with draw structure prevent wrinkling, solved a day font aluminium section bar when bending the outer wall depression, inwall is wrinkling and the problem of sidewall projection.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (1)
1. the forming method of bumper holder before and after the aluminium alloy is characterized in that, comprises the steps:
