Abstract

The invention discloses a bending device, and belongs to tools. The objective of the invention is to disclose a motor coil winding bending device which is high in bending efficiency and good in bending forming precision. The device comprises an upper die and a lower die, the upper die is composed of two pressing heads (2) fixedly arranged on a hydraulic machine, the bottom face of each pressing head (2) is of a semi-cylindrical structure, and a kidney-shaped guide hole (8) is formed in the center of each pressing head (2); the lower die (3) is fixed on the base (4), and two arc-shaped grooves(7) which are of semi-cylindrical structures and are matched with the bottom surfaces of the corresponding pressing heads (2) in shape are formed in the surface of the lower die (3); a kidney-shaped positioning hole is formed in the center of each arc-shaped groove (7), and two guide columns (1) fixed to the base (4) penetrate through the corresponding positioning holes and are matched with the corresponding guide holes (8). The device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a bending device, in particular to a motor coil winding bending device, which belongs to mechanical processing technology equipment. Background technique [0002] In order to make the motor coil winding fit more closely with the tile-shaped magnetic steel on the stator or rotor, after the coil is wound, it needs to be pressed into a tile-shaped structure. At present, simple molds are usually used to complete by hand. Not only is the labor intensity high and the efficiency is low, but also the positioning of the coil is determined by the operator's visual inspection, so it is difficult to ensure that the bending range is consistent with the magnetic steel, which affects the product quality. Contents of the invention [0003] In view of the above defects in the prior art, the present invention aims to provide a coil winding bending die with simple structure, convenient use, high bending efficiency and good bending forming prec...
