Plate bending machining device and method

Abstract

The invention belongs to the field of plate machining, and particularly relates to a plate bending machining device and method.The plate bending machining device comprises a fixed base and a first threaded rod, a connecting plate is fixedly mounted on the fixed base, a protective top plate is fixedly mounted at the top end of the connecting plate, and a mounting plate is fixedly connected to the connecting plate; a bending assembly, a clamping assembly and an angle display assembly are mounted on the mounting plate, a connecting plate is in threaded connection with the first threaded rod, the connecting plate is slidably connected to the mounting plate in a limiting mode, and a first sensor is fixedly mounted in the connecting plate; the bending device solves the problems that an existing bending device cannot conveniently and stably adjust the bending angle of a plate, meanwhile, the adjusted bending angle cannot be visually displayed in real time, and workers cannot clearly and accurately know the adjustment degree of the bending angle; therefore, the expected effect can be achieved only by multiple times of adjustment of workers, and convenience and stability of bending machining cannot be guaranteed.

Description

technical field [0001] The invention relates to the field of sheet metal processing, in particular to a sheet metal bending processing device and a processing method. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminium-wood composite doors and windows, aluminum-plastic composite doors and windows for short) base material and wood, plastic composite doors and windows, when the existing aluminum alloy doors and windows are produced, it is necessary to combine the use of bending devices to produce aluminum alloy plates. In order to process the aluminum alloy plate into a frame shape, some bending devices have some problems when working: [0003] Since the frames of conventional aluminum alloy doors and windows are mostly rectangular, the conventional bending devi...

AI Technical Summary

Problems solved by technology

[0003] Since the frames of conventional aluminum alloy doors and windows are mostly rectangular, the conventional bending device can only perform a single right-angle bending work on the sheet during the working process. With the continuous development of social economy, people's aesthetics gradually improves. , the shapes and styles of aluminum alloy doors and windows are gradually increasing, and the conventional bending device cannot adjust the bending angle of the sheet material conveniently and stably during the working process, and at the same time cannot adjust the adjusted bending angle. With real-time and intuitive display, the staff cannot clearly and accurately understand the adjustment degree of the bending angle, so the staff needs to make multiple adjustments to achieve the expected effect, which cannot guarantee the convenience and stability of the bending process; and when the sheet metal When it is relatively thick, the local stress will be too large during the bending process. If it exceeds the tensile strength of the material, it will cause damage; even if it does not exceed the tensile strength of the material, it will reduce the fatigue strength and bring safety hazards. The bending device cannot perform convenient and stable internal stress reduction processing on sheets of different thicknesses during the working process, and has poor practicability and low work efficiency. Therefore, it is necessary to provide a sheet metal bending processing device and processing method to Meet the needs of users
