Metal plate bending machine

Abstract

The invention discloses a metal plate bending machine, and relates to the technical field of metal plate machining equipment. The metal plate bending machine comprises a rack and an adjusting column,a bending column and an air cylinder which are installed on the rack. The rack is provided with a connecting mechanism used for being connected with the bending column. The connecting mechanism comprises a sliding groove perpendicular to the horizontal plane and a sliding block connected in the sliding groove in a sliding mode. Connecting pieces are arranged on the sliding block; and the connecting pieces are detachably connected to the two ends of the bent column. The bending column comprises a working part in the middle and connecting parts at the two ends. The connecting parts are interconnected with the connecting pieces. Each connecting piece comprises a cylindrical connecting column. According to the metal plate bending machine, the operator can conveniently disassemble, replace andadjust the bending column, the bending column surface treatment convenient for operators, the surface flatness of the bending column is ensured with no requirement for too much time for replacement orlong-time shutdown to cause waste of working time, reduction of the overall working efficiency is avoided and the normal production is ensured.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing equipment, in particular to a sheet metal bending machine. Background technique [0002] Generally speaking, the basic equipment of sheet metal process includes shearing machine, CNC punching machine, bending machine and so on. Generally, the four most important steps in the sheet metal process are shearing, cutting, folding, welding, and surface treatment. Sheet metal is sometimes used as wrench metal. Generally, some metal sheets are plastically deformed by manual or die stamping to form the desired shape and size, and can be further welded or a small amount of machining to form more complex parts, such as Commonly used chimneys in the home, tin stoves, and car casings are all sheet metal parts. [0003] The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracke...

Problems solved by technology

[0007] Although this automatic sheet metal bending machine solves the problem of manual adjustment of the height on both sides of the bending machine, which is very inconvenient, the bending column needs to be used repeatedly for a long time. The surface of the folding column will be uneven or deformed, which will easily affect the bending effect. At this time, the surface of the bending column needs to be treated to maintain the flatness of the contact surface, and this requires a long shutdown for the operator. operation, it is easy to waste more time and reduce work efficiency
