Multi-type pipe bending device with positioning and knocking functions for metal forming

Abstract

The invention discloses a multi-type pipe bending device with positioning and knocking functions for metal forming. The multi-type pipe bending device comprises a supporting mechanism, a hydraulic mechanism and a positioning mechanism, wherein the hydraulic mechanism is arranged on one side of the supporting mechanism, and the positioning mechanism is arranged on the upper surface of the supporting mechanism. When a bending plate needs to be bent slightly, a working box is moved to a designated position through telescopic long plates, meanwhile, a power source of electromagnetic plates is turned off, then a heavy ball falls down due to small magnetic force and knocks bent metal, meanwhile, due to the recovery performance of a spring, the heavy ball rebounds and rises, then the power source of the electromagnetic plates is turned on, the electromagnetic plates adsorb the heavy ball again, the process is repeated in sequence, the purpose of knocking and slightly bending the metal can be achieved, the quality of a bent metal finished product is good, the square metal can be fixedly clamped by using straight plates when the square metal is bent, the arc-shaped metal can be bent by retracting the straight plates in surface grooves when the arc-shaped metal is bent, the purpose of bending the arc-shaped metal can be achieved, and the fixing and clamping effects are better.

Description

technical field [0001] The invention relates to the technical field of metal bending equipment, in particular to a multi-type tube bending device with positioning knocking for metal forming. Background technique [0002] Bending means that the metal sheet first undergoes elastic deformation under the pressure of the upper or lower die of the bending machine, and then enters plastic deformation. In the initial stage of plastic bending, the sheet is free to bend. When the pressure is applied to the sheet, the sheet and the inner surface of the V-groove of the lower die are gradually closed, and at the same time the radius of curvature and the bending arm are gradually reduced, and the pressure is continued until the stroke ends, so that the upper and lower dies and the sheet are close at three points. At this time, a V-shaped bending is completed, which is commonly known as bending, and the bending machine is a machine that can bend thin plates. Its structure mainly includes b...

Problems solved by technology

[0003] The current metal bending device is difficult to micro-bend metal. When using a bending machine to bend metal, when the bending requirements are high, the bending arc is difficult to control, resulting in lower quality of the bent metal plate. Poor. Secondly, when fixing metal objects, they are all squeezed and fixed according to the shape of a square tube. When fixing round objects, the fixing firmness is poor
