A sheet metal panel bending tool and bending method

Abstract

The invention belongs to the field of sheet metal machining, and particularly relates to a sheet metal panel bending tool and a bending method. The sheet metal panel bending tool comprises a sheet metal panel, a base plate, a fixing plate, an electric air cylinder, a bending male die, a bending female die and sliding blocks; the fixing plate is welded to one side of the base plate, and a mountinggroove is formed in one side of the fixing plate; the electric air cylinder is fixedly connected to the side, opposite to the fixing plate, of the base plate through bolts; the bending female die is matched with the bending male die, and the bending female die is fixedly arranged in the mounting groove in the fixing plate through bolts; the bending male die is detachably installed on the mountingbase arranged at the end of the electric air cylinder through a clamping block; the sliding blocks are symmetrically distributed on the two sides of the electric air cylinder, and the sliding blocks can slide in sliding grooves arranged on the base plate; and the end part of the electric air cylinder is fixedly connected to the sliding blocks through steel wire ropes. The sheet metal panel bendingtool and the bending methodhave the advantages that the structure is simple, the operation is convenient, and the problem that the bending angle of batch sheet metal panels cannot meet the requirement in the prior art can be solved.

Description

technical field [0001] The invention belongs to the field of sheet metal processing, in particular to a sheet metal panel bending tool and bending method. Background technique [0002] Sheet metal processing is a processing method in which sheet metal panels are processed by shearing, punching, cutting, folding, etc., and then processed into products by welding, riveting, splicing, etc. The sheet metal process is also due to its low cost and good mass production performance. And other characteristics have been developed rapidly. When producing structural parts that can be assembled into formed sheet metal products, it is often necessary to bend the panel to make the panel meet the assembly requirements, which is convenient for fixing and forming when assembling sheet metal products later. [0003] Due to the toughness of sheet metal materials, the bent sheet metal plate is prone to rebound and recovery during bending processing, resulting in the fixed edge after bending not ...

Problems solved by technology

[0003] Due to the toughness of sheet metal materials, the bent sheet metal plate is prone to rebound and recovery during bending processing, resulting in the fixed edge after bending not meeting the production requirements. On the one hand, it will affect the appearance of the assembled product, and on the other hand On the one hand, the deformation of the sheet metal panel will affect the smoothness of riveting or splicing when assembling products. Therefore, it is very meaningful to prevent the obvious rebound recovery of the sheet metal panel after bending. In order to solve this problem, the present invention provides The following technical solutions
