Problems solved by technology

[0002] Metal sheet stamping has a wide range of applications. It not only changes the shape of the sheet to make it beautiful, but also can use thinner materials under the same strength requirements. However, the traditional processing technology requires high mold precision, complex processing, and high mold costs. , inconvenient to use, it is easy to cause damage to equipment and molds

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 Shown is a schematic diagram of a 3-diameter cross-section of a metal sheet.

[0017] figure 2 Shown is the mold processing diameter section of adopting prior art such as figure 1 The schematic diagram of shown metal sheet 3, this mold comprises die 4 and punch 5, the concave surface of die 4 and the protruding surface shape of metal sheet 3 aperture section, size are consistent, the convex face of punch 5 and metal sheet The shape and size of the concave surface of the 3-diameter cross-section are consistent. When the mold is processed, the dimensions of the die 4 and the punch 5 must be matched very accurately, and the processing is difficult; at the same time, when the protruding part of the metal sheet 3 is When the U-shaped ring is in shape, it is more difficult to guarantee the processing of the mold; and duri...

Abstract

The invention discloses a metal sheet molding die. The molding die comprises a female die and a male die, wherein the caliber size of a concave part of the female die is the same as that of a corresponding convex part of the metal sheet; the projection height of the male die is the same as the depression depth of a corresponding concave part of the metal sheet; the cross sectional shape of the caliber of the concave part of the female die can be different from that of the caliber of the corresponding convex part of the metal sheet; and the cross sectional shape of the caliber of the convex part of the male die can be different from that of the caliber of the corresponding concave part of the metal sheet. Compared with the prior art, the die of the invention is simple to process, has low manufacturing cost and is economical and practical; friction between the inclined surface and the curved surface of a workpiece is prevented by gap molding and the surface of a product is smooth, round, scratch-free and attractive; and when the die is used, a machine tool and the die per se are difficult to damage in installation and debugging processes and convenient use is achieved.

Description

technical field [0001] The invention relates to a mold, in particular to a thin metal plate forming mold. Background technique [0002] Metal sheet stamping has a wide range of applications. It not only changes the shape of the sheet to make it beautiful, but also can use thinner materials under the same strength requirements. However, the traditional processing technology requires high mold precision, complex processing, and high mold costs. , it is inconvenient to use, and it is easy to cause damage to equipment and molds. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies of the prior art and provide a thin metal sheet forming die, which adopts the die gap method for forming, has low requirements on the precision of the die, and is not easy to cause damage to equipment and dies. [0004] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adop...
