Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic wire processing, and particularly relates to a high-efficiency multi-aperture wire drawing device for electromagnetic wires. Background Art

[0002] Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products. During the processing of electromagnetic wire, the initial width of the electromagnetic wire is uniformly standardized. However, in the subsequent use, according to the different needs of customers, the electromagnetic wire needs to be processed into different diameters. This requires a wire drawing step: that is, the electromagnetic wire to be processed is preheated, and then the electromagnetic wire is processed into the required size through a wire drawing die.

[0003] Publication number CN216779877U discloses an efficient multi-aperture wire drawing device for electromagnetic wire, including a feeding device, a preheating device, a forming device and a collecting device, the feeding device including a first reel and a first rotating motor for driving the first reel to rotate, one end of the electromagnetic wire to be processed is connected to the first reel, the preheating device includes a shell and a heating element connected to the shell, the shell is provided with a through hole, the through hole is adapted to the cross-sectional shape and size of the electromagnetic wire to be processed, the forming device includes a forming base and several mounting bases connected to the forming base, the forming base is provided with a hollow groove, the hollow groove passes through the forming base, the mounting base is provided with a shaped hole passing through the mounting base, the aperture of the cross section of one end of the shaped hole is larger than the aperture of the cross section of the other end, and the aperture size of the shaped holes in different mounting bases is different, the collecting device includes a second reel and a second rotating motor for driving the second reel to rotate.

[0004] By arranging protective pads on the left and right sides of the mounting base, the mounting base can be protected to avoid relative sliding between the mounting bases, which affects the processing effect of the electromagnetic wire. However, there is no device for pre-tightening the electromagnetic wire. Since the structure of the electromagnetic wire softens after heating, if pre-tightening is not performed, the electromagnetic wire will shake when passing through the forming hole, affecting the drawing effect of the electromagnetic wire.
