A cutting device for the production of fine enameled wire

Abstract

This utility model relates to the technical field of wind turbine equipment, specifically a cutting device for the production of fine enameled wire. The cutting device includes a mounting bracket with a cutting mechanism located in the middle. The advantages are as follows: by replacing the insulating replacement mesh, opening the L-shaped spring clip, and pulling the insert block out of the fixed slot, the enameled wire slides in the threading groove until it is about to reach between the fixed clamping plate and the movable clamping plate. Then, the two reset levers are pulled to reset and align until the movable clamping plate and the fixed clamping plate clamp several enameled wires in the threading groove. At this point, the wire clamping mechanism with the fixed enameled wire can be inserted into the mounting groove, so that the fixed block is inserted between the two reset levers, and the spring fixing pin abuts against the two reset levers to clamp the wire clamping mechanism, thus fixing the wire clamping mechanism to the insulating replacement mesh. This achieves rapid feeding and accurate positioning of a large quantity of enameled wire.

Description

Technical Field

[0001] This utility model relates to the field of wind turbine equipment manufacturing technology, specifically a cutting device for the production of fine enameled wire. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.

[0003] In the production and processing of enameled wire, it is often necessary to cut it to a fixed length according to process requirements, and then the cut wire segments are conveyed to the next process, such as winding, insertion, or welding. Especially in the automated production of micro-enameled wire (the diameter is usually less than 0.1 mm), the material feeding process after cutting directly affects production efficiency and product consistency.

[0004] Currently, in existing technologies, the reconnection of cut enameled wires largely relies on manual operation. The common practice is to place multiple cut enameled wires together in a material box or tray, and then have an operator pick them up one by one and manually fix them onto a winding machine. In some more automated machines, a vibratory feeder combined with a rail conveyor is used, or a robotic arm is used to grasp and feed individual wires. However, the efficiency of connecting and reconnecting wires manually, whether by machine or by hand, is low, labor-intensive, and human error can lead to inaccurate reconnection positions, affecting the quality of subsequent processing.

[0023] Example 1

[0024] Please see Figures 1-5This utility model provides a technical solution: a cutting device for the production of fine enameled wire, the cutting device for the production of fine enameled wire includes: a mounting bracket 1, a cutting mechanism 2 disposed in the middle of the mounting bracket 1, the mounting bracket 1 including a bottom fixing frame 11, a top fixing frame 12 fixedly connected to the top of the bottom fixing frame 11, a wire feeding roller 13 rotatably connected to one end of the top fixing frame 12, a motor 14 fixedly connected to one end of the bottom fixing frame 11, a wire gathering mechanism 5 fixedly connected to the output end of the motor 14, and an adjusting screw 15 rotatably connected to the middle of the bottom fixing frame 11. The outer wall of the adjusting screw 15 is threadedly connected to a wire guide mechanism 3. Both the wire gathering mechanism 5 and the inner wall of the wire guide mechanism 3 are fitted with wire clamping mechanisms 4. The wire guide mechanism 3 includes a movable mounting plate 31, the two sides of which are slidably connected to a top fixing frame 12. A fixing groove 32 is formed on the top of the movable mounting plate 31, and an L-shaped spring clip 33 is rotatably connected to the top of the movable mounting plate 31. The wire clamping mechanism 4 includes an insert block 41, the outer wall of which is inserted into the interior of the fixing groove 32. A fixing clamping plate 42 is fixedly connected to the top of the insert block 41, and a sliding groove 43 is formed on the top of the insert block 41. An anti-detachment block 44 is slidably connected to the inner wall of 43. A movable clamping plate 45 is fixedly connected to the top of the anti-detachment block 44. The movable clamping plate 45 is slidably connected to one side of the fixed clamping plate 42. Several wire-passing grooves 47 are opened through the side walls of both the movable clamping plate 45 and the fixed clamping plate 42. The number of wire-passing grooves 47 on the movable clamping plate 45 and the fixed clamping plate 42 are equal and correspond one-to-one. A reset lever 46 is fixedly connected to the top of both the movable clamping plate 45 and the fixed clamping plate 42. When the two reset levers 46 are aligned, the wire-passing grooves 47 on the movable clamping plate 45 and the fixed clamping plate 42 are misaligned. The cable gathering mechanism 5 includes... The device includes a wire-collecting roller 51, with a mounting groove 52 extending through its side wall. A wire clamping mechanism 4 is inserted into the inner wall of the mounting groove 52. An isolation replacement mesh 55 is slidably connected to the outer wall of the wire-collecting roller 51. Each isolation replacement mesh 55 corresponds to a wire-passing groove 47. One end of each isolation replacement mesh 55 abuts against the wire-passing groove 47. A fixing block 53 is fixedly connected to one end of the wire-collecting roller 51. The fixing block 53 is inserted into the inner wall of a slot formed by two reset levers 46. Spring fixing pins 54 are provided at both ends of the fixing block 53. The side walls of the two spring fixing pins 54 abut against the two reset levers 46 respectively.

[0025] It should be noted that when it is necessary to continue feeding the enameled wire, the operator can remove the wire clamping mechanism 4 installed on the wire collecting roller 51 and the isolation replacement net 55 that has already been wound with enameled wire. Then, replace the isolation replacement net 55, open the L-shaped spring clip 33, and pull out the insert 41 from the fixed groove 32. When the enameled wire slides in the wire threading groove 47 and is about to reach between the fixed clamping plate 42 and the movable clamping plate 45, pull the reset lever 46 to drive the anti-detachment block 44 to slide on the inner wall of the slide groove 43 until the movable clamping plate 45 and the fixed clamping plate 42 close the wire threading groove 47. Several enameled wires are clamped and fixed. At this time, the wire clamping mechanism 4 with the fixed enameled wires can be passed between the bottom clamping plate 24 and the top clamping plate 25 and inserted into the mounting groove 52. The fixing block 53 is inserted between the two reset levers 46 until several wire-passing grooves 47 correspond to the isolation replacement net 55. The spring fixing nail 54 abuts against the two reset levers 46 to lock the wire clamping mechanism 4, and the wire clamping mechanism 4 is fixed to the isolation replacement net 55. Then, a new wire clamping mechanism 4 is inserted into the conductor mechanism 3 so that the enameled wire passes through the wire-passing groove 47, and the material feeding is completed.

[0026] The cutting mechanism 2 is located between the wire clamping mechanism 4 and the wire gathering mechanism 5. The cutting mechanism 2 includes an operating table 21. A motor 22 is fixedly connected to one side of the operating table 21. An eccentric wheel 23 is fixedly connected to the output end of the motor 22. The eccentric wheel 23 is rotatably connected to the operating table 21. A top clamping plate 25 is fixedly connected to the top of the eccentric wheel 23. A shearing blade is fixedly connected to the bottom of the top clamping plate 25. A bottom clamping plate 24 is fixedly connected to the top of the operating table 21. A shearing table is fixedly connected to the top of the bottom clamping plate 24. The shearing blade meshes with the shearing table.

[0027] It should be noted that the operator winds several enameled wires to be cut onto the wire feeding roller 13, passes one end of the wires through the wire-feeding groove 47 on the wire clamping mechanism 4 installed on the conductor mechanism 3, and then through the bottom clamping plate 24 and the top clamping plate 25 until they are fixed into the wire clamping mechanism 4 installed on the wire gathering mechanism 5. The starting motor 14 drives the wire gathering mechanism 5 to rotate, winding several enameled wires onto the outer wall of the wire gathering roller 51 between several isolation replacement meshes 55, until the position where the enameled wires need to be cut reaches between the shearing blade and the shearing table on the top clamping plate 25 and the bottom clamping plate 24. The operator starts the second motor 22 to drive the eccentric wheel 23 to rotate, and the eccentric wheel 23 drives the shearing blade and the shearing table on the top clamping plate 25 and the bottom clamping plate 24 to cut the several enameled wires, thus quickly realizing the cutting of several enameled wires.

[0028] In actual use, the operator winds several enameled wires to be cut onto the wire feeding roller 13. One end of each wire is passed through the wire-feeding groove 47 on the wire clamping mechanism 4 installed on the conductor mechanism 3, and then through the space between the bottom clamping plate 24 and the top clamping plate 25 until it is fixed inside the wire clamping mechanism 4 installed on the wire collecting mechanism 5. The starting motor 14 drives the wire collecting mechanism 5 to rotate, winding several enameled wires onto the outer wall of the collecting roller 51 between several isolation replacement meshes 55 until the position where the enameled wire needs to be cut reaches between the shearing blade and shearing table on the top clamping plate 25 and the bottom clamping plate 24. The operator then starts the second motor 22 to drive the eccentric wheel 23 to rotate. The eccentric wheel 23 drives the shearing blade and shearing table on the top clamping plate 25 and the bottom clamping plate 24 to cut the several enameled wires, quickly achieving the cutting of several enameled wires. When it is necessary to continue feeding the enameled wires, the operator can connect the wire clamping mechanism 4 installed on the collecting roller 51 to the already wound wire isolation mesh. Remove the replacement mesh 55, then replace the isolation replacement mesh 55. Next, open the L-shaped spring clip 33 and pull out the insert 41 from the fixing slot 32. When the enameled wire slides in the threading slot 47 and is about to reach between the fixed clamp 42 and the movable clamp 45, pull the reset lever 46 to drive the anti-disengagement block 44 to slide on the inner wall of the slide groove 43 until the movable clamp 45 and the fixed clamp 42 clamp and fix several enameled wires in the threading slot 47. At this time, the wire clamping machine with the fixed enameled wire can be used. Mechanism 4 passes between the bottom clamping plate 24 and the top clamping plate 25 and is inserted into the mounting groove 52, so that the fixing block 53 is inserted between the two reset levers 46 until several wire-passing grooves 47 correspond to the isolation replacement net 55, so that the spring fixing nail 54 abuts against the two reset levers 46 to lock the wire clamping mechanism 4, and fix the wire clamping mechanism 4 and the isolation replacement net 55. Then, insert a new wire clamping mechanism 4 into the conductor mechanism 3 so that the enameled wire passes through the wire-passing groove 47, and the material feeding is completed.
