Embodiment Construction

[0018] Embodiment given in conjunction with accompanying drawing, the present invention is described:

[0019] Such as figure 1 As shown, a thin plate stamping die whose size is larger than the closed height of the press includes a die handle 1, a punch 10, a die 8, an upper die 2, a lower die 5, a positioning plate 9, a guide device 11, a support block 4 and rubber Block 3 etc. The punch 10 and the die 8 are composed of multiple sets, which are fixed on the upper template 2 and the lower template 5 respectively, and deviate from the stamping die center 13; the upper template 2 and the lower template 5 adopt guiding devices 11 for positioning and guiding to ensure the concentricity of the punch and die during stamping; the guide device 11 is composed of a guide sleeve arranged at the bottom of the upper template and a guide column arranged at the upper part of the lower template, and the guide sleeve corresponds to the guide column set up. The size of the lower template 5 i...

Abstract

The invention belongs to the technical field of the stamping, and provides a thin-plate stamping mold with the size being greater than a closed height of a press machine and a stamping method. The thin-plate stamping mold with the size being greater than the closed height of the press machine comprises a mold handle (1), convex molds (10), concave molds (8), an upper molding plate (2) and a lower molding plate (5); the convex molds and the concave molds are formed in one set and are respectively located on the upper molding plate (2) and the lower molding plate (5); a punch-die center (12) of the stamping mold is deviated from the center (13) of the stamping mold, i.e. the convex molds (10) and t he concave molds (8) are deviated from the center (13) of the stamping mold; the size of the lower molding plate (5) is greater than that of a working platform (6), and when the stamping mold is in stamping use, a thin plate is arranged on one side of the working platform; and the concave molds (8) are fixed on one side of the lower molding plate (5), and the other side of the lower molding plate (5) is fixedly provided with a supporting block (4). Due to the adoption of the stamping mold and the stamping method, the stamping problem of a thin plate with the size being greater than the closed height of the press machine can be solved.

Description

technical field [0001] The invention belongs to the technical field of stamping, and relates to a sheet stamping die and a stamping method whose size is larger than the closed height of a press. Background technique [0002] Stamping dies are widely used in the stamping and forming of protective covers, shells, filters, partition covers, end caps and other parts of motorcycles, automobiles, and electrical appliances. Most of the stamping parts of these parts are symmetrical to the center of the stamping die. In practice, it is often encountered that stamping or punching is performed on the side of the part. [0003] In the current technology, the side stamping method, one is to make a special mechanism, move downward through the upper die base and the upper side punching mechanism, and under the action of the lower side punching mechanism, the vertical direction of the punch fixed on the upper side punching mechanism will be fixed. direction movement, which is converted int...
