Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a metal door frame bending machine. Background Art

[0002] A bending machine, also known as a press brake, is a press machine that uses mechanical or hydraulic operation. Currently, in the production process of various types of metal sheets, a bending machine is required to process the shape of the sheet. For example, when producing door structures, it is usually necessary to bend the metal sheet into a U-shaped blank, so that it is easy to assemble it on one side of the door structure.

[0003] Still taking the above-mentioned processing of metal sheets as an example, currently, bending the sheet into a U-shaped blank requires stamping on both sides of the sheet. Therefore, after the first stamping, the worker needs to adjust the sheet to change the force-bearing surface of the sheet to complete the second stamping process. However, the manual adjustment method is very dependent on the concentration of the human body. During the work process, the concentration and physical strength of the human body will continue to decline, and it is impossible to maintain efficient and accurate work, thus affecting production.

[0004] In summary, it is necessary to make necessary improvements to the existing bending machines. Utility Model Content
