A metal plate bending deformation processing mold

Abstract

The invention belongs to the technical field of plate processing, and in particular relates to a metal plate bending deformation processing mold, which includes a horizontal bottom plate, a guide rod is installed on the bottom plate, a pressure bearing plate is installed on the guide rod, and a pressure applying plate is slidably installed on the guide rod; The pressure bar is fixedly installed between the pressure plates, and the pressure bar is fixedly installed between the pressure plates; the vertical plate is installed on the bottom plate, and the horizontal plate is installed on the top of the vertical plate; A threaded screw, the first lead screw runs through the gantry frame and fits with the gantry frame through threads; the first recompression mechanism is installed on the bottom plate; the second recompression mechanism is installed on the pressure bar; between the vertical plate and the pressure receiving plate Install the tensioning mechanism. When bending and shaping the metal sheet through the metal sheet bending deformation processing mold of the present invention, a pressure with a constant size and a direction always perpendicular to its surface can be applied to the edge of the metal sheet, thereby avoiding springback of the metal sheet; damage its shape.

Description

Technical field [0001] The present invention belongs to the field of sheet processing technology, and more particularly to a metal plate curved deformation process mold. Background technique [0002] The metal sheet is a common building component and manufacturing process. During the actual use, it is necessary to process the metal sheet into different shapes. The main method is to stamped by a flat metal sheet to make it fixed. shape. During the actual processing production process, when the metal thin plate material is made by mold stamping, the following problems are presented: (1) Since the metal thin plate material is lighter, the mold is stamped, due to the sheet and the mold The air is emptied, and the sheet is tightly attached to the surface of the mold under the action of the air pressure. At this time, it is necessary to manually remove the sheet of stamped, and the shape of the sheet is easily destroyed during artificial removal process; (2); (2) When the existing mold...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a bending deformation processing die for sheet metal, aiming to solve the following problems existing in bending and deformation of thin metal sheet through die stamping: (1) Since the sheet metal itself is relatively light, after the die stamps it, Since the air between the plate and the mold is evacuated, the plate will be tightly attached to the surface of the mold under the action of air pressure. At this time, the stamped plate needs to be removed manually. The shape of the plate is easy to be damaged during the manual removal process. The forming quality is reduced; (2) When the existing mold stamps and forms the metal sheet, the pressure direction and size of the metal sheet are uneven, resulting in partial springback of the formed metal sheet after stamping is completed , which also reduces the forming quality of sheet metal
