Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic wire processing technology, specifically relating to an electromagnetic wire feeding device. Background Technology

[0002] When electromagnetic wires leave the factory, they are usually stored and transported in the form of "coil winding". During this process, due to factors such as winding tension, the elasticity of the material itself, and changes in temperature and humidity of the storage environment, the wires may not be able to straighten naturally after leaving the coil, but instead appear bent, spiral, or partially twisted. Such morphological defects will directly affect the quality of subsequent processing.

[0003] Existing electromagnetic wire laying devices typically employ a rigid structure—either using metal clamps or multiple sets of metal rollers to press and directly contact the insulation layer of the electromagnetic wire for straightening. However, improper clamping force control can easily cause scratches or detachment of the insulation layer, increasing the risk of leakage. Furthermore, these devices are not compatible with electromagnetic wires of different diameters, affecting subsequent processing. Therefore, there is a need to provide an electromagnetic wire laying device to address these technical problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5This embodiment provides the following technical solution: an electromagnetic wire feeding device, including a processing table 1, a front guide frame 2 fixedly connected to the processing table 1, and a straightening mechanism 3 provided at the right end of the front guide frame 2 for straightening the electromagnetic wire being fed; the straightening mechanism 3 includes an adjusting frame 31, a lower clamping plate 32 fixedly connected to the bottom of the adjusting frame 31, an upper clamping plate 33 slidably connected to the adjusting frame 31 above the lower clamping plate 32, and flexible pads 34 fixedly connected to opposite sides of the upper clamping plate 33 and the lower clamping plate 32, the two flexible pads 34 working together to form a clamping channel through which the electromagnetic wire passes; with the cooperation of the upper clamping plate 33, the lower clamping plate 32 and the flexible pads 34, the device can completely fit the surface of the electromagnetic wire, avoiding direct contact between the electromagnetic wire and any rigid parts, making the surface of the electromagnetic wire uniformly stressed, applicable to electromagnetic wires of various specifications, reducing component replacement costs, lowering maintenance costs, and improving service life.

[0027] A first screw 35 is threaded through the upper clamping plate 33 on the adjusting frame 31. The lower end of the first screw 35 is rotatably connected to the upper clamping plate 33, and the upper end of the first screw 35 is fixedly connected to a first handle 36. The distance between the upper clamping plate 33 and the lower clamping plate 32 can be adjusted by the first screw 35 and the first handle 36, thereby adjusting the size of the clamping channel and making it suitable for clamping electromagnetic wires of different specifications.

[0028] In some embodiments, the flexible pad 34 is made of paper made of plant fibers or regenerated fibers. When the paper comes into contact with the surface of the electromagnetic wire, it generates moderate sliding friction. On the one hand, it slowly releases the residual stress inside the electromagnetic wire, and on the other hand, it "straightens" the local bending section through frictional resistance, forcing the electromagnetic wire to move along the channel direction. Moreover, the paper (usually kraft paper or insulating paper) is soft in texture, which can avoid scratching the insulating layer (such as the enameled layer or silk-covered layer) on the surface of the electromagnetic wire compared to direct contact with metal clamps. At the same time, the slight deformation of the paper adapts to electromagnetic wires of different diameters, improving the clamping and sealing performance.

[0029] A limiting mechanism 4 is also provided on the front guide frame 2 in front of the straightening mechanism 3. The limiting mechanism 4 includes a fixed seat 41 and guide rods 43. A support roller 42 is fixedly connected to the fixed seat 41. Two symmetrically arranged guide rods 43 are slidably connected to the right side of the support roller 42. The front and rear guide rods 43 work together to form a limiting channel for the electromagnetic wire. During the wire feeding process, the electromagnetic wire contacts the upper edge of the support roller 42 through the support roller 42, which can support the electromagnetic wire. The electromagnetic wire is limited during the feeding process by the guide rods 43 on both the front and rear sides.

[0030] A first lead screw 44 is rotatably connected to the fixed base 41 below the support roller 42. A knob 46 is fixedly connected to one end of the first lead screw 44. A drive plate 45 corresponding to the guide rod 43 is threaded onto the first lead screw 44. The drive plate 45 is fixedly connected to the lower end of the guide rod 43. The threads on the front and rear sides of the first lead screw 44 are in opposite directions. The lower surface of the drive plate 45 is in contact with the bottom of the fixed base 41, and the upper surface of the drive plate 45 is in contact with the lower edge of the support roller 42. When the knob 46 is rotated, the two drive plates 45 on the first lead screw 44 move closer or further away at the same time, adjusting the limiting channel through which the electromagnetic wire passes and limiting the electromagnetic wire.

[0031] A rear guide frame 5 is also provided on one side of the front guide frame 2 on the processing table 1. A front guide mechanism 6 is provided above the rear guide frame 5. The front guide mechanism 6 includes two fixed plates 61 arranged in parallel with each other. A movable plate 62 is slidably connected to the opposite side of the two fixed plates 61. First guide rollers 63 are arranged above the two movable plates 62. In some embodiments, the two fixed plates 61 are symmetrically fixedly connected to the front and rear sides of the rear guide frame 5. The first guide rollers 63 on the front and rear movable plates 62 cooperate to limit the side of the electromagnetic wire and guide the electromagnetic wire.

[0032] A second lead screw 64 is rotatably connected between two fixed plates 61. A second handle 65 is fixedly connected to the front end of the second lead screw 64. The second lead screw 64 passes through the threaded holes provided on the two movable plates 62 and is threadedly connected to the movable plates 62. The threads on the front and rear sides of the second lead screw 64 are in opposite directions. A first limiting rod 66 is provided on both the left and right sides of the second lead screw 64 and is fixedly connected to the two fixed plates 61. The first limiting rod 66 moves through the first limiting groove provided on the two fixed plates 61. By using the second lead screw 64 and the first limiting rod 66, the second handle 65 can be rotated, and the movable plates 62 on the front and rear sides can be adjusted to move closer or further apart at the same time, thereby adjusting the distance between the first guide rollers 63 on the front and rear sides. This is suitable for electromagnetic wires of different specifications to pass through, improving the wire feeding effect.

[0033] A rear guide mechanism 7 is also provided on the right side of the front guide mechanism 6 on the rear guide frame 5. The rear guide mechanism 7 includes two positioning plates 71 arranged in parallel to each other. The two positioning plates 71 are symmetrically distributed vertically. A movable plate 72 is slidably connected between the two positioning plates 71. The front sides of the movable plate 72 and the lower positioning plate 71 are provided with interlaced second guide rollers 73. Through the interlaced second guide rollers 73, the upper and lower sides of the electromagnetic wire can be limited again after the electromagnetic wire is guided by the front guide mechanism 6, which further improves the wire feeding effect.

[0034] A second screw 74 is rotatably connected between the upper and lower positioning plates 71. A third handle 75 is fixedly connected to the upper end of the second screw 74. The second screw 74 passes through a threaded hole on the movable plate 72 and is threadedly connected to the movable plate 72. Second limiting rods 76 are fixedly connected to the two positioning plates 71 on the left and right sides of the second screw 74. The upper and lower ends of the second limiting rods 76 are fixedly connected to the two positioning plates 71 respectively. The second limiting rods 76 move through the second limiting grooves on the positioning plates 71. Through the second screw 74 and the third handle 75, the second screw 74 can be rotated to drive the movable plate 72 to move up or down, adjusting the distance between the upper and lower sets of second guide rollers 73, which is suitable for electromagnetic wires of different specifications.

[0035] Example 2

[0036] The flexible pad 34 can be made of a wear-resistant polymer material. In some embodiments, the wear-resistant polymer material can be selected from at least one of rubber, silicone, polyurethane foam or nylon. The wear-resistant polymer material is both flexible and wear-resistant, and can adapt to the surface of the electromagnetic wire through deformation to avoid damage to the insulation layer. It is easy to process and can be made into various thicknesses and shapes. It is compatible with most small and medium diameter (0.5-3mm) electromagnetic wires and does not require frequent replacement.

[0037] Example 3

[0038] The flexible pad 34 can be made of fiber fabric material. In some embodiments, the fiber fabric material can be selected from at least one of cotton cloth, linen cloth, fiberglass cloth or microfiber cloth. The surface of the fiber fabric material is delicate and soft, and there is no risk of scratching the electromagnetic wire insulation layer. It is lightweight, breathable, and has no problem of stuffiness and aging. Some varieties (such as fiberglass cloth) have strong high temperature resistance.

[0039] Example 4

[0040] The flexible pad 34 can also be made of a flexible metal material. In some embodiments, the flexible metal material can be selected from thin copper sheets, thin aluminum sheets or phosphor bronze sheets with a thickness of 0.05-0.1mm. The flexible metal material has a balance of rigidity and flexibility, sufficient clamping force, and is suitable for electromagnetic wires with a large diameter (2-4mm). It has extremely strong wear resistance and a long service life. It is resistant to high temperature and chemical corrosion and is suitable for extreme working conditions.

[0041] The working principle of this utility model is as follows: When in use, the electromagnetic wire passes sequentially through the support roller 42, the channel formed between the two guide rods 43, the channel formed between the two flexible pads 34, the channel formed between the first guide rollers 63 on the two moving plates 62, and the channel formed between the movable plate 72 and the second guide rollers 73 on the lower positioning plate 71.

[0042] When it is necessary to adjust the distance between the two guide rods 43, simply turn the knob 46 to make the first screw 35 rotate, causing the front and rear drive plates 45 and guide rods 43 to move closer or further away at the same time, thus adjusting the distance between the two guide rods 43.

[0043] When it is necessary to adjust the distance between the upper clamping plate 33 and the lower clamping plate 32, simply turn the first handle 36 to make the first screw 35 rotate, causing the upper clamping plate 33 to move closer to or further away from the lower clamping plate 32, thereby adjusting the distance between the two flexible pads 34.

[0044] When it is necessary to adjust the distance between the first guide rollers 63 on the two moving plates 62, simply turn the second handle 65 to make the second lead screw 64 rotate. Under the limiting action of the first limiting rod 66, the two moving plates 62 move closer or further away at the same time, thereby changing the distance between the first guide rollers 63 on the two moving plates 62.

[0045] When it is necessary to adjust the distance between the movable plate 72 and the second guide roller 73 on the lower positioning plate 71, simply turn the third handle 75 to rotate the second screw 74. Under the limiting action of the second limiting rod 76, the movable plate 72 can be moved closer to or further away from the lower positioning plate 71, thereby changing the distance between the upper second guide roller 73 and the lower second guide roller 73.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
