Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and specifically to a bending machine with convenient internal limiting. Background Technology

[0002] Hardware processing is the process of using lathes, milling machines, drilling machines, or polishing machines to process raw materials into various parts according to customer drawings or samples. In hardware processing, bending machines play a crucial role, enabling the processing of metal materials such as steel, aluminum, and copper into various shapes, including inward bending, outward bending, corner bending, and flanging.

[0003] Chinese utility model patent CN218611145U discloses a high-efficiency bending machine, which includes "a limiting plate provided on the outer surface of the fixed plate, and an adjustment mechanism provided on the outer surface of the limiting plate, the adjustment mechanism including a connecting plate, a toothed plate, a toothed block, and a spring, which facilitates the adjustment and limiting of iron plates of different sizes." However, the limiting component of the bending machine is fixedly installed, which makes it inconvenient to quickly adjust the limiting component and to maintain it. Utility Model Content

[0004] The purpose of this invention is to provide a bending machine with convenient internal limiting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending machine with convenient internal limiting, comprising a bending machine body, a bending table installed on one side surface of the bending machine body, an adjusting table installed on one side surface of the bending table, limiting holes being provided on the top surface and one side surface of the adjusting table, a limiting component being installed on the top surface of the adjusting table, and a trapezoidal sliding groove being provided on the inner wall of the adjusting table.

[0006] The limiting assembly includes a mounting plate installed on the top surface of the adjusting platform. An oil pump is mounted on the top surface of the mounting plate. One end of an oil guide pipe is mounted on one side surface of the oil pump. A hydraulic cylinder is mounted on the other end of the oil guide pipe. One end of a piston rod is mounted on one side surface of the hydraulic cylinder. A limiting plate is mounted on the other end of the piston rod. A slider is mounted on the bottom surface of both the mounting plate and the limiting plate. Spring pins are mounted on the top surface and one side surface of the mounting plate.

[0007] The beneficial effects of this utility model are as follows: the limiting component can limit both ends of the metal plate to prevent displacement when bending the metal plate, and the limiting component and the adjusting table are designed to be easily disassembled, so that the position of the limiting component can be quickly adjusted and the limiting component can be quickly maintained.

[0008] To achieve rapid docking between the limit switch assembly and the adjustment platform:

[0009] As a further improvement to the above technical solution: the limiting component forms a sliding mechanism through a slider and a trapezoidal groove.

[0010] The beneficial effects of this improvement are as follows: With the above settings, the mounting plate of the limit component and the limit plate can be quickly plugged into and installed on the adjustment table by using the slot of the slider and the adjustment table, which effectively improves the installation efficiency.

[0011] To achieve rapid fixing of the limit component and the adjustment platform:

[0012] As a further improvement to the above technical solution: the size and structure of the limiting hole are consistent with the size and structure of the spring pin.

[0013] The beneficial effects of this improvement are as follows: With the above settings, after the limiting component is moved to the appropriate position according to the different widths of the metal plate, the limiting component can be quickly fixed by the spring pins on the top and side of the mounting plate cooperating with the limiting holes of the adjusting table, which effectively improves the installation efficiency.

[0014] To achieve the limiting of both ends of the metal plate:

[0015] As a further improvement to the above technical solution: the limiting plate forms a telescopic mechanism with the hydraulic cylinder via a piston rod.

[0016] The beneficial effects of this improvement are as follows: With the above settings, the oil pump inputs hydraulic oil into the hydraulic cylinder through the oil guide pipe, controls the extension and retraction of the piston rod, and thus controls the extension and retraction of the limit plate. The limit plate can quickly limit both ends of the metal plate, preventing deviation when bending the metal plate and affecting the processing quality.
