Description

Technical Field

[0001] The present application relates to the technical field of sheet metal bending, and specifically to a sheet metal bending device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, and forming such as automobile bodies. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. Some sheet metal parts generally need to be bent by a bending device before use.

[0003] A Chinese patent application with application number CN202222474942.6 discloses a sheet metal bending device. This solution includes a bottom frame, and two frame plates are fixedly connected to the top side of the bottom frame. A cavity is opened inside the two frame plates, and a motor is fixedly connected to the inner wall of the bottom side of the bottom frame. In this application, a reciprocating screw is set, and the motor generates a driving force. When the reciprocating screw continues to rotate, it can drive the upper module to move back and forth up and down and then cooperate with the lower module to complete the bending of the sheet metal. Compared with the comparative document, it can avoid the motor from constantly rotating forward and reverse, thereby effectively reducing the wear rate of the components and the loss of potential energy, and also effectively improving the service life and reducing the production cost; by setting a top block, when the upper module cooperates with the lower module to bend the sheet metal, the top block can lift the bent sheet metal, so that it is convenient for workers to take out the bent sheet metal.

[0004] The fixed curvature of the bending groove in the above solution makes it impossible to adjust the curvature of the bending groove according to customer needs. Especially when dealing with automotive sheet metal bending tasks, multiple bending machines have to be used for operation, which will increase corporate costs and increase employee labor intensity.

[0037] All electrical equipment in this solution are powered by an external power supply.

[0038] Working principle: When the user is bending the sheet metal, the user places the bent sheet metal on the upper part of the bending groove 36, and turns on the electric push rod 22.

The V-shaped bending groove 35 corresponds to the V-shaped bending groove 35, and the sheet metal can be bent into different curvatures by turning on the electric push rod 22 again, thereby reducing the fixity of the curvature of the bending groove 36, making it impossible to adjust a variety of bending curvatures according to customer needs. In particular, when dealing with automotive sheet metal bending tasks, a variety of bending machines have to be used for operation.
