A stamping method for stamping large metal sheets

Abstract

The invention relates to a stamping method for large metal plate stamping. The stamping method comprises steps of preparing preparation, plate regulating, assembling and fixing, stamping, plate stacking, and the like. Movable stamping equipment adopted comprises a movable bracket, wherein a threaded fixed hole is formed in the movable bracket; an extrusion gas cylinder is mounted on the inner wallof the upper end of the movable bracket; and the top end of the extrusion gas cylinder is mounted on an extrusion moulding block through a flange. The stamping method can solve the following problemsin an existing large metal plate stamping processing process that: a, relatively large metal plates cannot be operated by a common stamping lathe, an occupied site of large stamping equipment is relatively great, needed supporting facilities are more, and processing cost is high; and b, existing movable stamping equipment cannot avoid the bending deformation problem generated after metal plates are extruded by external force, easily causea accumulation of errors in a stamping process, and cannot guarantee precision of stamping operation.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a stamping method for stamping large sheet metal. Background technique [0002] Sheet metal stamping is one of the common methods in sheet metal processing. According to the required shape, the metal sheet is stamped into a specified shape. In the process of sheet metal stamping, it is necessary to perform conventional atmospheric pressure treatment on large sheets. Generally, the sheet metal There are a number of predetermined shapes that are punched at equal intervals on a plane structure. When it is necessary to punch a large metal sheet into a V-shaped structure at equal intervals, there are many issues to be considered, and the quality of sheet metal stamping must be strictly guaranteed. [0003] However, the following problems exist in the stamping process of the existing large-scale metal sheets, a. The ordinary stamping lathes for larger metal sheets cannot...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the stamping process of the existing large-scale metal sheets, a. The ordinary stamping lathes for larger metal sheets cannot perform operations, while large-scale stamping equipment occupies a large space, requires many supporting facilities, and the processing cost is high. , b The existing mobile stamping equipment cannot avoid the problem of bending and deformation of the metal sheet after being squeezed by external force during the stamping operation, which will easily lead to the accumulation of errors in the stamping process and cannot guarantee the accuracy of the stamping operation

[0004] Regarding some problems existing in the sheet metal stamping process, related industries have done research and put forward specific technical solutions, such as the Chinese utility model patent No. A sheet metal stamping equipment, by designing the connecting material level at the bottom of the product On the bending edge of the design, and a unique continuous die stamping sequence is used for this design, however, the problems mentioned above about stamping large plates are not covered
