A processing device for preventing wear of resistance wires

Abstract

The present invention belongs to the technical field of resistance wire processing, and in particular to a processing device for preventing resistance wire wear. In view of the fact that the existing resistance wire needs to be wound during the wire drawing process, as the winding progresses, the radius of the winding will become larger and larger. If the speed of the winding roller cannot be adjusted accordingly, the moving speed of the resistance wire will become faster and faster, thereby causing the problem of wear. The following scheme is proposed, which includes a tensioning component, a winding component and an adaptive adjustment component; the tensioning component is configured to adjust the tension of the resistance wire; the winding component is configured to wind the resistance wire in sequence; the adaptive adjustment component is configured to adaptively adjust the winding speed in accordance with the winding radius of the winding component, so that the winding speed of the resistance wire is uniform.

Description

Technical Field

[0001] The present invention relates to the technical field of resistance wire processing, and in particular to a processing device for preventing resistance wire from being worn. Background Art

[0002] The resistance wire drawing process involves stretching metal materials (such as copper and nickel-chromium alloys) into thinner wires for use in manufacturing electronic components such as resistors. During the winding process, friction occurs between the resistance wire and the winding spool or other surfaces. This friction causes the metal layer on the resistance wire's surface to gradually wear away. This friction increases, and the wear becomes more severe, particularly when the winding speed is high or the winding spool surface is rough. Therefore, the winding speed needs to be controlled. However, as the winding progresses, the radius of the wound resistance wire gradually increases. To control the winding speed, the rotation speed of the winding roller needs to be controlled, so that the rotation speed of the winding roller gradually decreases as the winding radius increases. Summary of the Invention

[0030] Example

[0031] Reference Figure 1-Figure 3 , a processing device for preventing resistance wire wear, comprising a tensioning assembly, a winding assembly and an adaptive adjustment assembly 5;

[0032] The tensioning assembly is configured to adjust the tension of the resistance wire. The tensioning assembly includes a mounting plate 1 fixedly mounted on a workbench 4 and surrounded on three sides. Tensioning wheels 2 are mounted on the mounting plates 1 on both sides through elastic telescopic rods, and a rotating wheel 3 is mounted on the middle mounting plate 1.

[0033] The winding assembly is configured to sequentially wind the resistance wire. The winding assembly includes a winding roller 512 and a lead structure located above the winding roller 512. The lead structure includes a first guide rod 515 arranged along the length of the winding roller 512. A sliding block 516 is mounted on the first guide rod 515. A lead drum 513 is mounted on the sliding block 516. The sliding block 516 is slidably connected to a reciprocating screw rod 514. The reciprocating screw rod 514 and the winding roller rotate synchronously via a synchronous belt and pulley.

[0034] like Figure 3-5As shown, the adaptive adjustment component 5 is configured to adaptively adjust the winding speed in accordance with the winding radius of the winding component, so that the winding speed of the resistance wire is uniform. The adaptive adjustment component 5 includes a driving shaft 522 driven by a motor and a driven shaft 521 driven by the driving shaft 522. The driving shaft 522 and the driven shaft 521 are equipped with a stepless speed change component. The stepless speed change component includes a fixed disk 510, a sliding disk 509 and a metal transmission belt 511. The sliding disk 509 can slide along the length direction of the driving shaft 522 and the driven shaft 521. A coaxial driving member 518 is also installed outside the driving shaft 522 and the driven shaft 521. The driving member 518 is rotatably connected to the sliding disk 509 through a plane bearing 519. The driving member 518 is slidably connected to the second guide rod 520. The two ends of the second guide rod 520 are fixedly connected to the bracket. The second guide rod 520 is arranged parallel to the driving shaft 522 and the driven shaft 521.

[0035] A lever 517 for controlling the transmission ratio is installed on the upper part of the stepless speed change assembly. Both ends of the lever 517 are rotatably connected to the driving member 518 through a pin shaft. A driving rod 508 is fixed at the center of the lever 517. The driving rod 508 is rotatably connected to the bracket through a bearing. A grooved wheel 504 is fixedly installed on the driving rod 508. A third ratchet mechanism 503 for non-return is installed on the top of the lever 517. A first active dial and a second active dial 505 are respectively installed on both sides of the grooved wheel 504. The first active dial is coaxially connected to the first ratchet mechanism. The second active dial 505 is coaxially connected to the second ratchet mechanism 507, and the sliding block 516 is fixedly connected to the slide bar 501 through a connecting rod. The first rack 502 and the second rack 506 are installed on the slide bar 501. The first rack 502 moves forward and cooperates with the first ratchet mechanism to drive the first active dial to rotate the groove wheel 504 one grid toward the driven shaft 521. The second rack 506 moves backward and cooperates with the second ratchet mechanism 507 to drive the second active dial 505 to rotate the groove wheel 504 one grid toward the driven shaft 521.

[0036] The working principle of this application is:

[0037] The motor drives the active shaft 522 to rotate, and the active shaft 522 drives the driven shaft 521 to rotate through the continuously variable transmission assembly. The rotation of the driven shaft 521 drives the winding roller 512 to rotate, and the rotation of the winding roller 512 drives the reciprocating screw rod 514 to rotate. The reciprocating screw rod 514 rotates to drive the sliding block 516 to slide back and forth. The movement of the sliding block 516 drives the first rack 502 and the second rack 506 to move. The first rack 502 moves forward and cooperates with the first ratchet mechanism to drive the first active dial to toggle the groove wheel 504 toward the driven When the shaft 521 rotates one grid, the second rack 506 moves back and cooperates with the second ratchet mechanism 507 to drive the second active dial 505 to toggle the groove wheel 504 to rotate one grid toward the driven shaft 521. Each time the groove wheel 504 rotates one grid, the continuously variable transmission assembly is adjusted once. That is, each time the groove wheel 504 rotates one grid, the sliding plate 509 on the driven shaft 521 moves one grid closer to the fixed plate 510, so that the radius of the metal transmission belt 511 at the driven wheel becomes larger, causing the continuously variable transmission to switch to a low speed state.

[0038] The above process is repeated, that is, the winding speed of the winding roller 512 is automatically adjusted each time a layer of resistance wire is wound, so that the winding speed of the resistance wire tends to be balanced during the winding process, avoiding the increase in wear caused by changes in the winding speed of the resistance wire.

[0039] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. The embodiments of the present invention and the features therein can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
