Slotting type metal plate bending device

Abstract

The invention relates to the field of metal plates, in particular to a slotting type metal plate bending device. According to the technical scheme, the slotting type metal plate bending device comprises a working machine bottom plate, a slotting system, a pressurizing bending system and a bending seam welding system; and the slotting system, the pressurizing bending system and the bending seam welding system are sequentially connected to the upper portion of the working machine bottom plate. The center of a plate is slotted before bending, normal bending of materials is guaranteed, the phenomenon that the left side and the right side of a fold line in a central fold line area extrude each other and then protrude reversely is avoided, a thin metal plate is bent in positioned and protected modes through slotting, obtuse-angle and acute-angle bending with the accurate angle is achieved, and a crack on the outer side of the bent part in the bending process of the acute-angle metal plate isrepaired in positioned and welded modes.

Description

technical field [0001] The invention relates to the field of sheet metal, in particular to a slotted sheet metal bending device. Background technique [0002] Sheet metal, a processing technology, sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold processing process for metal sheets, including shearing, punching / cutting / compositing, folding, riveting, splicing, forming, etc. [0003] At present, in the sheet metal bending process in the prior art, when the metal sheet is bent at an obtuse angle, most of the metal sheet can maintain the strength of the raw material after bending, but when the acute angle bending is performed, some metal sheets Slight fractures will occur on the outside of the bend, that is, the strength of this kind of plate will decrease after bending, and it cannot be used as a high-strength support member. They squeeze each ot...

Problems solved by technology

[0005] In order to overcome the existing technology in the sheet metal bending process, when the metal sheet is bent at an obtuse angle, most of the metal sheet can maintain the strength of the raw material after bending, but when performing an acute angle bend, some metal sheets Slight fractures will occur on the outside of the bend, that is, the strength of this kind of plate will decrease after bending, and it cannot be used as a high-strength support member. Mutual extrusion, and then reverse protrusion, affecting the shortcoming of the passage inside the bending angle, the technical problem to be solved by the present invention: provide a slotted sheet metal bending device
