Abstract

The invention relates to a simply-molded mold design and a molding method applicable to stretching and molding. The molding method comprises the following specific steps that: firstly, according to product plate structures, a simple fixed template (1), a lower template (2) and a punch head mold (3) matched with a position of the product plate (4) required to be stretched and molded are designed; then according to the structure of the designed product plate (4), the fixed template (1) and the lower template (2) are cut by LASER, and a first groove (6) and a second groove matched with the punch head mold (3) is formed on the fixed template (1) and the lower template (2), and the fixed template (1), the lower template (2) and the product plate (4) are fixed by a locating pin (5), so that the fixed template (1), the lower template (2) and the product plate (4) are positioned in an overlaid way; and finally, the punch head mold (3) is put into the first groove (6) of the fixed template (1) and pressed by a bending machine so that a protruding part of the product plate (4) is formed in a second concave template.

Description

A kind ofly be applicable to stretch and simple forming Design of Dies and the forming method of processing and forming

Technical field

The present invention designs a kind of drawing and forming technology, especially a kind ofly is applicable to stretch and simple forming Design of Dies and the forming method of processing and forming.

Background technology

Among panel beating making, particularly some new-product development, relate to stretching and forming processing technology field, must adopt purchase capstan head mould and manufacturing cold-punching mold to finish in the past.Obviously take this traditional moulds to carry out the research and development of new product, for the enterprise that main employing stretching and moulding process are made product, not only the cost compare of Mold Making is high, R﹠D cycle is also long, simultaneously because the increase of the unsuccessful R﹠D costs of bringing of grinding tool also is the risk that the Corporation R ﹠ D new product must be born.

Therefore, for the enterprise that is engaged in stretching and forming processing technology field, how to finish new-product development with more easy mould, solve the really new problem that relates to the problems in stretching and the processing and forming in producing.

Summary of the invention

Purpose of the present invention: be intended to propose a kind ofly be applicable to stretch and cost free simple forming mould and the forming method in forming processing technology field.

Thisly be applicable to stretch and simple forming Design of Dies and the forming method of processing and forming, its concrete way is: at first according to the easy fixed form of the structural design of production board, lower bolster, and need the supporting drift mould in drawing and forming place with production board; Then cut fixed form and lower bolster according to the structure of the production board that designs with LASER, on fixed form and lower bolster, form respectively the first groove and the second groove that is complementary with the drift mould, then fix fixed form, lower bolster and production board with alignment pin, make the stacked location of three; At last the drift mould is put in the first groove of fixed form, with the bender pressurization protrusion place of production board is formed among the second groove.

Material thickness between fixed form, lower bolster, production board and the drift of employing said method should be followed following relational expression: production board degree of drawing=drift mould thickness-upper masterplate thickness, lower bolster thickness=molding thickness.

Thisly be applicable to stretch and cost free simple forming mould and the forming method in forming processing technology field according to what above technical scheme proposed, by ad hoc easy fixed head, lower bolster and with the supporting drift in need drawing and forming place, utilize bender will need to stretch and the light sheet material of processing and forming forms needed configuration state, owing to save traditional capstan head mould and made cold-punching mold, therefore had more widely applied value.

Description of drawings

Fig. 1 is that fixed form used in the present invention, counterdie arrange schematic diagram;

Fig. 2 is the drift of the drawing and forming shape of wanting;

Fig. 3 is finished product schematic diagram behind the drawing and forming;

Die assembly mode schematic diagram when Fig. 4 is stretching.

Among the figure: 1-fixed form 2-lower bolster 3-drift mould 4-production board 5-fixed form 6-groove

Specific implementation method

Further set forth the present invention below in conjunction with Figure of description, and provide embodiments of the invention.

Thisly be applicable to stretch and simple forming Design of Dies and the forming method of processing and forming, its concrete way is: at first according to the easy fixed form 1(of the structural design of production board cope match-plate pattern), lower bolster 2 and need the supporting drift mould 3 in drawing and forming places with production board 4; Then cut fixed form 1 and lower bolster 2 according to the structure of the production board that designs with LASER, on fixed form 1 and lower bolster 2, form respectively the first groove 6 and the second groove that is complementary with drift mould 3, then fix fixed form 1, lower bolster 2 and production board 4 with alignment pin 5, make the stacked location of three; At last drift mould 3 is put into 6 li of first grooves of fixed form 1, with the bender pressurization protrusion place of production board 4 is formed among the second groove.

Material thickness coupling between fixed form, lower bolster, production board and the drift mould of employing said method should be followed following relational expression: production board degree of drawing=drift mould thickness-upper masterplate thickness, lower bolster thickness=molding thickness.

The present invention is mainly at shaped article.Performance by stage die principle and bender designs and produces some and uses material 1mm; 2mm; 3mm makes simple die (such as Fig. 1).

The 1 structural design low-cost die according to production board.

2 according to the product that designs LASER cutting die.

3 die-cut are finished with alignment pin and are fixed upper/lower die and product orientation, the drift mould are put into fixedly make product protrude the place among concave template with the bender pressurization in the board slot.

Claims

1. one kind is applicable to stretch and simple forming Design of Dies and the forming method of processing and forming, its concrete way is: at first according to the easy fixed form of structural design (1), the lower bolster (2) of production board (4), and need the supporting drift mould (3) in drawing and forming place with production board (4); Then cut fixed form (1) and lower bolster (2) according to the structure of the production board that designs (4) with LASER, on fixed form (1) and lower bolster (2), form respectively the first groove (6) and the second groove that is complementary with drift mould (3), then use alignment pin (5) to fix fixed form (1), lower bolster (2) and production board (4), make the stacked location of three; It is inner at last drift mould (3) to be put into first groove (6) of fixed form (1), with the bender pressurization protrusion place of production board (4) is formed among the second groove.
