Description

Technical Field

[0001] This utility model belongs to the field of resistance wire production and processing technology, and specifically relates to a polishing device for resistance wire production and processing. Background Technology

[0002] A resistance wire is an electrical component that converts electrical energy into internal energy. Generally speaking, the resistance of a metal increases with rising temperature; the opposite is true for carbon, semiconductors, or electrolytes, where the resistance decreases with rising temperature. Thus, within a certain temperature range, the temperature change and the resistance change can be considered to be linearly related, and therefore the temperature change can be converted into a resistance change. In the production of resistance wires, polishing is a crucial process, as the surface roughness of the resistance wire affects its performance.

[0003] Patent application number 202310713117.3 discloses a polishing device for resistance wire production and processing, including a base; a feeding component and a receiving component are respectively provided at both ends of the base; a splicing component one, a cutting component, a primary polishing component, a splicing component two, and a secondary polishing component are arranged sequentially in the wire traction direction; a detection component for detecting wire breakage is provided on the front and rear sides of the primary polishing component, and a limiting component one and a limiting component two are provided on the front and rear sides of the secondary polishing component; the splicing component one and the splicing component two are used to connect the wires; the cutting component is used to cut the wires; the primary polishing component and the secondary polishing component are used to perform multi-stage polishing treatment on the wires.

[0004] The above technical solution uses a rotary polishing mechanism to polish the outer wall of the resistance wire. However, during the polishing process, the protrusions on the resistance wire need to be polished repeatedly. The excessive friction between the incompletely polished protrusions and the inner wall of the rigid polishing part will cause it to bear a large torque. When the resistance wire is subjected to a large torque, it is prone to breakage, resulting in poor safety of polishing the resistance wire. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a polishing device for resistance wire production and processing. This polishing device aims to solve the technical problem of poor safety in resistance wire polishing caused by the fact that during the polishing process, the protrusions on the resistance wire need to be polished repeatedly. The excessive friction between the incompletely polished protrusions and the inner wall of the rigid polishing part leads to the resistance wire bearing a large torque, which can easily cause the resistance wire to break.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a polishing device for resistance wire production and processing. The polishing device includes a base and a primary polishing tube and a secondary polishing tube disposed on both sides of the top surface of the base. A storage box is fixed to the top of the base, and a drive mechanism for rotating the secondary polishing tube is disposed above the base. The inner wall of the primary polishing tube has a primary polishing cavity with a funnel-shaped structure, and the inner wall of the secondary polishing tube has a secondary polishing cavity. An air bladder is embedded in the inner wall of the secondary polishing cavity, and polishing sandpaper is fixed to the inner wall of the air bladder by Velcro.

[0009] When using this technical solution, a primary polishing tube and a secondary polishing tube are respectively set above the base. The primary polishing chamber on the inner wall of the primary polishing tube scrapes off the protrusions on the outer wall of the resistance wire body for initial polishing. The motor drives the secondary polishing tube to rotate through the first gear and the second gear. The polishing sandpaper on the secondary polishing chamber on the inner wall of the secondary polishing tube rotates and polishes the resistance wire body. When the protrusions on the outer wall of the resistance wire body come into contact with the polishing sandpaper, the air bladder on the polishing sandpaper is squeezed and elastically contracted, thereby reducing the friction and torque between the protrusions of the resistance wire body and the polishing sandpaper. The pressure of the air bladder keeps the polishing sandpaper in contact with the outer wall of the resistance wire body. The rapid rotation of the polishing sandpaper polishes the protrusions on the resistance wire body multiple times to complete the polishing, which greatly reduces the torque borne by the resistance wire during polishing and improves the safety of the resistance wire polishing. By fixing a storage box at the top of the base, two coolant delivery pipes cool the resistance wire before the secondary polishing through water pumps, thereby reducing the temperature of the resistance wire body during polishing.

[0010] Preferably, both ends of the primary polishing tube and the second polishing tube are provided with mounting plates, and the bottom ends of the plurality of mounting plates are fixedly connected to the base.

[0011] Furthermore, a conveying roller and a winding roller are respectively provided on both sides of the top surface of the base, and both ends of the conveying roller and the winding roller are provided with support plates fixed to the base.

[0012] Furthermore, a resistance wire body is provided between the conveying roller and the winding roller, and the resistance wire body is slidably inserted into the primary polishing cavity and the secondary polishing cavity in sequence.

[0013] Furthermore, coolant delivery pipes are installed at both ends of the side wall of the storage tank. The top ends of the two coolant delivery pipes correspond to the resistance wire body on one side of the first-stage polishing pipe and the second-stage polishing pipe, respectively, and the bottom ends of the coolant delivery pipes extend into the storage tank and are equipped with water pumps.

[0014] Furthermore, the drive mechanism includes a motor fixed to the side wall of the mounting plate and a second gear fixedly sleeved on the secondary polishing tube, and a first gear that meshes with the second gear is mounted on the motor shaft.

[0015] Furthermore, an air inlet pipe connected to the airbag is fixedly installed on the outer wall of the secondary polishing tube, and a control valve is installed on the air inlet pipe. Both ends of the polishing sandpaper are matched with the secondary polishing cavity.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a primary polishing tube and a secondary polishing tube positioned above the base. The primary polishing chamber on the inner wall of the primary polishing tube scrapes away the protrusions on the outer wall of the resistance wire body for initial polishing. A motor drives the secondary polishing tube to rotate via a first gear and a second gear. The polishing sandpaper on the secondary polishing chamber on the inner wall of the secondary polishing tube rotates and polishes the resistance wire body. When the protrusions on the outer wall of the resistance wire body come into contact with the polishing sandpaper, the air bladder on the polishing sandpaper is squeezed and elastically contracted, thereby reducing the friction and torque between the protrusions on the resistance wire body and the polishing sandpaper. The pressure of the air bladder keeps the polishing sandpaper in contact with the outer wall of the resistance wire body. The rapid rotation of the polishing sandpaper repeatedly polishes the protrusions on the resistance wire body, thus completing the polishing process. This significantly reduces the torque borne by the resistance wire during polishing and improves the safety of the resistance wire polishing process.

[0019] By fixing a storage tank at the top of the base, two coolant delivery pipes are used to cool the resistance wire before the secondary polishing by water pumps, thereby reducing the temperature of the resistance wire body during polishing. Attached Figure Description

[0026] 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.

[0027] This specific embodiment is a polishing device for resistance wire production and processing, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the polishing device for resistance wire production and processing includes a base 1 and a primary polishing tube 7 and a secondary polishing tube 2 disposed on both sides of the top surface of the base 1. A storage box 4 is fixed to the top of the base 1, and a drive mechanism for rotating the secondary polishing tube 2 is disposed above the base 1. The inner wall of the primary polishing tube 7 is provided with a primary polishing cavity 14 in the shape of a funnel, and the inner wall of the secondary polishing tube 2 is provided with a secondary polishing cavity 17. An air bladder 15 is embedded and fixed in the inner wall of the secondary polishing cavity 17, and polishing sandpaper 16 is fixed to the inner wall of the air bladder 15 by Velcro.

[0028] Mounting plates 10 are provided at both ends of the primary polishing tube 7 and the secondary polishing tube. The bottom ends of multiple mounting plates 10 are fixedly connected to the base 1. Conveying rollers 6 and winding rollers 9 are respectively provided on both sides of the top surface of the base 1. Support plates 5 fixed to the base 1 are provided at both ends of the conveying rollers 6 and winding rollers 9. The driving mechanism includes a motor 13 fixed to the side wall of the mounting plate 10 and a second gear 12 fixedly sleeved on the secondary polishing tube 2. A first gear 11 meshing with the second gear 12 is installed on the shaft of the motor 13. The motor 13 drives the secondary polishing tube 2 to rotate through the first gear 11 and the second gear 12. The polishing sandpaper 16 on the secondary polishing cavity 17 on the inner wall of the secondary polishing tube 2 rotates and polishes the resistance wire body 8.

[0029] like Figure 3 and Figure 4As shown, a resistance wire body 8 is disposed between the conveying roller 6 and the winding roller 9. The resistance wire body 8 is slidably inserted into the primary polishing chamber 14 and the secondary polishing chamber 17 in sequence. The conveying roller 6 and the winding roller 9 convey and wind the resistance wire body 8 for polishing, which is existing technology and will not be described in detail here. Coolant delivery pipes 3 are installed at both ends of the side wall of the storage tank 4. The top ends of the two coolant delivery pipes 3 correspond to the resistance wire body 8 on one side of the primary polishing pipe 7 and the secondary polishing pipe, respectively. The bottom ends of the coolant delivery pipes 3 extend into the storage tank 4 and are equipped with water pumps. The two coolant delivery pipes 3 cool the resistance wire before secondary polishing through the water pumps, thereby reducing the temperature of the resistance wire body 8. During grinding, an air inlet pipe 18 connected to an air bladder 15 is fixedly installed on the outer wall of the secondary polishing tube 2. A control valve is installed on the air inlet pipe 18. Both ends of the polishing sandpaper 16 are matched with the secondary polishing chamber 17. When the protrusion on the outer wall of the resistance wire body 8 abuts against the polishing sandpaper 16, the air bladder 15 on the polishing sandpaper 16 is squeezed and elastically contracted, thereby reducing the friction and torque between the protrusion on the resistance wire body 8 and the polishing sandpaper 16. The pressure of the air bladder 15 makes the polishing sandpaper 16 always abut against the outer wall of the resistance wire body 8, and the protrusion on the resistance wire body 8 is polished multiple times by the rapid rotation of the polishing sandpaper 16, which greatly reduces the torque borne by the resistance wire during polishing.

[0030] Working principle: When using the device of this technical solution, the resistance wire body 8 between the conveying roller 6 and the winding roller 9 is conveyed between the primary polishing tube 7 and the secondary polishing tube 2. The primary polishing cavity 14 on the inner wall of the primary polishing tube 7 scrapes off the protrusions on the outer wall of the resistance wire body 8 for preliminary polishing. The motor 13 drives the secondary polishing tube 2 to rotate through the first gear 11 and the second gear 12. The polishing sandpaper 16 on the secondary polishing cavity 17 on the inner wall of the secondary polishing tube 2 rotates and polishes the resistance wire body 8. When the protrusions on the outer wall of the resistance wire body 8 come into contact with the polishing sandpaper 16, the air bladder 15 on the polishing sandpaper 16 is squeezed and elastically contracted, thereby reducing the friction and torque between the protrusions of the resistance wire body 8 and the polishing sandpaper 16. The pressure of the air bladder 15 keeps the polishing sandpaper 16 in contact with the outer wall of the resistance wire body 8. The polishing is completed by repeatedly polishing the protrusions on the resistance wire body 8 through the rapid rotation of the polishing sandpaper 16, which greatly reduces the torque borne by the resistance wire during polishing and improves the safety of the resistance wire polishing. A storage box 4 is fixed at the top of the base 1.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
