Abstract
The utility model relates to the technical field of automobile appliances, in particular to a metal outer casing molding structure of an automobile sound installation. An outer casing comprises a central panel and peripheral folded edges and is molded via punching, and press lines which are arranged at jointed portions of a central panel area and peripheral folded edges of a molding board are slot structures. During a punch molding process, the press lines can reduce stress, decrease deformation during pulling, guarantee planeness of the central panel and stabilize molding edges and corners, thereby stabilizing quality of products, achieving smooth mass production, having high yield and saving raw materials and cost.
Description
Technical field:
The utility model relates to the Automobile Products technical field, refers in particular to a kind of metal shell molding structure of automobile audio.
Background technology:
The metal shell of traditional automobile audio adopts punch forming to make, promptly utilize sheet material to process corresponding specification after, the shell body that cooperates mould to stamp out again to have flanging.Yet, owing to the stress of sheet material inside, during the metal shell moulding of traditional automobile audio, realize limit, angle poor stability, the median plate face is subject to draw material, causes flatness to reduce, and the quality instability of shaped article is difficult to produce in enormous quantities.
The utility model content:
The purpose of this utility model is to overcome the defective of prior art, and a kind of metal shell molding structure of automobile audio is provided.
For achieving the above object, the utility model adopts following technical scheme:
The metal shell molding structure of automobile audio, this shell include the flanging of median plate face and periphery, adopt punch forming; Junction between the flanging part of the median plate facial zone of sheet forming and periphery is provided with line ball, and line ball is a wire casing structure.
The line ball segment design is centered around week outside the median plate face.
The utility model is that the junction between the flanging part of the median plate facial zone of sheet forming and periphery is provided with line ball, so that in the punch forming process, subdue stress by line ball, draw material when reduce stretching, guarantee the flatness of median plate face, and moulding limit, angle are stable, make constant product quality, reach smooth volume production, the rate of finished products height economizes in raw materials and cost.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model forming;
Accompanying drawing 2 is the attached view of structure of Fig. 1;
Accompanying drawing 3 is the structural representation of the sheet forming of the utility model.
Embodiment:
Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:
Consult Fig. 1, Fig. 2 and shown in Figure 3 clearly, it is the structural representation of the preferred embodiment of the utility model, the utility model is the metal shell molding structure of relevant a kind of automobile audio, this shell includes the flanging 2 of median plate facial 1 and periphery, adopt punch forming, junction between the flanging part of the median plate facial zone of sheet forming and periphery is provided with line ball 3, and line ball 3 is a wire casing structure.Line ball 3 segment design are centered around week outside the median plate face 1.
During punch forming, line ball 3 forms one separation trough, the stress of material internal when subduing punching press, reduce the median plate facial zone and when stretching, draw material, guarantee the flatness of facial 1 moulding of median plate, and moulding limit, angle are stable, make constant product quality, reach smooth volume production, the rate of finished products height economizes in raw materials and cost.
Claims (2)
1. the metal shell molding structure of automobile audio, this shell includes the flanging (2) of median plate face (1) and periphery, adopt punch forming, it is characterized in that: the junction between the flanging part of the median plate facial zone of sheet forming and periphery is provided with line ball (3), and line ball (3) is a wire casing structure.
