Wire rod slitting device

Abstract

This utility model discloses a wire slitting device, including a support base and a wire adjustment mechanism, a wire conveying and protection mechanism, and a wire slitting mechanism disposed on the support base. The support base is horizontally arranged. The wire adjustment mechanism is located at one end of the support base for adjusting the tension or guiding position of the wire. The wire conveying and protection mechanism is located beside the wire adjustment mechanism for conveying and protecting the wire. The wire slitting mechanism is located beside the wire conveying and protection mechanism for slitting the wire. This utility model provides stable intermediate constraint to the wire before slitting by continuously clamping it with upper and lower conveying rollers. Even if one end of the wire loses tension at the moment of slitting, the clamping force of the conveying rollers can still limit the release speed of the wire's elasticity, preventing high-speed flying and fundamentally reducing the risk of personal injury to operators and damage to surrounding equipment.

Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a wire slitting device. Background Technology

[0002] Wires (such as copper wire, aluminum wire, cable, optical fiber, enameled wire, etc.) are the "basic building materials" in the fields of electronics, power, automobiles, communications, and home appliances. The diversification of their application scenarios has directly promoted the technological development of slitting devices.

[0003] During the cutting process, the wire needs to be kept taut so that the distance the wire is fed forward can be accurately determined, allowing for better cutting.

[0004] However, in existing wire cutting operations, when the wire is taut, the cutting point often lacks a corresponding protection mechanism. At the moment of cutting, the wire loses its original tensile constraint, and its accumulated elasticity is rapidly released, causing the wire to fly off course. This problem not only may lead to additional breakage during the flight (such as breakage after impact or breakage due to excessive stretching), but also poses a safety hazard due to the high-speed ejection of the wire, threatening the personal safety of operators and surrounding equipment. Utility Model Content

[0005] The purpose of this invention is to provide a wire cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wire slitting device includes a support base and a wire adjustment mechanism, a wire conveying and protection mechanism, and a wire slitting mechanism disposed on the support base. The support base is horizontally arranged. The wire adjustment mechanism is disposed at one end of the support base for adjusting the tension or guiding position of the wire. The wire conveying and protection mechanism is disposed next to the wire adjustment mechanism for conveying and protecting the wire. The wire slitting mechanism is disposed next to the wire conveying and protection mechanism for slitting the wire.

[0008] A further technical solution is provided, wherein the wire adjustment mechanism includes an adjusting screw shaft, an adjusting disc, an adjusting block, two slide rails, and two mounting seats. The two mounting seats are symmetrically arranged on the support base. The two ends of the adjusting screw shaft are rotatably connected to the two mounting seats. The adjusting disc is located at the end of the adjusting screw shaft. The two slide rails are symmetrically arranged on both sides of the two mounting seats. The adjusting block is slidably engaged with the two slide rails. The adjusting block is threadedly connected to the adjusting screw shaft. The top of the adjusting block is provided with two supports, and a detachable wire roller is provided between the two supports.

[0009] In a further technical solution, the wire adjustment mechanism further includes an adjustment seat, an adjustment roller, and an adjustment screw. The adjustment seat has an adjustment groove, the adjustment screw is vertically threaded onto the adjustment seat, the adjustment roller has a wheel seat, the top of the wheel seat is rotatably connected to the bottom of the adjustment screw, and the wheel seat slides up and down within the adjustment groove.

[0010] A further technical solution is provided, wherein the wire conveying protection mechanism includes a conveying seat, an upper conveying roller, a lower conveying roller, and a conveying motor. The conveying seat is provided with a conveying groove, and the two ends of the upper conveying roller are respectively provided with sliding blocks. The side wall of the conveying seat is provided with a sliding groove for the sliding blocks to slide. The lower conveying roller is horizontally rotatably connected inside the conveying seat and is arranged parallel to the upper conveying roller. The conveying motor is located on the conveying seat and is drivenly connected to the lower conveying roller. The top of the conveying seat is provided with two adjusting electric cylinders, and the extension and retraction ends of the two adjusting electric cylinders are respectively connected to the top of the two sliding blocks. The upper conveying roller is provided with a cam, and the lower conveying roller is provided with a groove that slides and engages with the cam.

[0011] A further technical solution includes a wire slitting mechanism comprising a slitting seat disposed beside the conveyor seat, the slitting seat having a slitting groove, a slitting base disposed within the slitting groove, a slitting blade groove disposed on the slitting base, a slitting cylinder disposed on the top of the slitting seat, and a slitting blade disposed on the telescopic end of the slitting cylinder.

[0012] In a further technical solution, the adjusting groove, the conveying groove, and the cutting groove are connected in a straight line.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the adjusting electric cylinder drives the upper conveyor roller to move downward, bringing it closer to the lower conveyor roller. This clamps the wire between the cam on the upper conveyor roller and the groove on the lower conveyor roller. Through the continuous clamping of the upper and lower conveyor rollers, a stable intermediate constraint is provided for the wire before slitting. Even if one end of the wire loses tension at the moment of slitting, the clamping force of the conveyor rollers can still limit the release speed of the wire's elasticity, preventing it from flying off at high speed and fundamentally reducing the risk of personal injury to operators and damage to surrounding equipment.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-5 As shown; this utility model provides a technical solution for a wire slitting device: a wire slitting device includes a support base 1 and a wire adjustment mechanism 2, a wire conveying and protection mechanism 3, and a wire slitting mechanism 4 disposed on the support base 1. The support base 1 is horizontally arranged. The wire adjustment mechanism 2 is disposed at one end of the support base 1 for adjusting the tension or guiding position of the wire. The wire conveying and protection mechanism 3 is disposed beside the wire adjustment mechanism 2 for conveying and protecting the wire. The wire slitting mechanism 4 is disposed beside the wire conveying and protection mechanism 3 for slitting the wire.

[0024] In this embodiment, refer to Figure 2As shown, the wire adjustment mechanism 2 includes an adjusting screw shaft 20, an adjusting disc 21, an adjusting block 22, two slide rails 23, and two mounting seats 24. The two mounting seats 24 are symmetrically arranged on the support base 1. The two ends of the adjusting screw shaft 20 are rotatably connected to the two mounting seats 24. The adjusting disc 21 is located at the end of the adjusting screw shaft 20. The two slide rails 23 are symmetrically arranged on both sides of the two mounting seats 24. The adjusting block 22 is slidably engaged with the two slide rails 23. The adjusting block 22 is threadedly connected to the adjusting screw shaft 20. The top of the adjusting block 22 is provided with two supports 25, and a detachable wire roller 26 is provided between the two supports 25. The wire roller 26 can hold the wire to be cut. After cutting one roll of wire, the wire roller 26 can be removed from the two supports 25 and replaced with a new wire roller 26.

[0025] When the operator rotates the adjusting disc 21, the adjusting screw shaft 20 rotates synchronously. Since the adjusting block 22 is threadedly connected to the adjusting screw shaft 20 and slides with the slide rails 23 on both sides, the rotational motion of the adjusting screw shaft 20 is converted into the horizontal linear motion of the adjusting block 22 along the slide rail 23. This, in turn, drives the wire roller 26 between the two supports 25 at the top of the adjusting block 22 to move horizontally, thereby achieving horizontal calibration of the wire unwinding position and ensuring that the starting point of the wire conveying is aligned with the subsequent conveying groove 35 and slitting groove 42. Furthermore, during the conveying of the wire, the tightness and tension of the wire are adjusted to avoid measurement errors in the conveying distance caused by wire slack, laying the foundation for subsequent accurate slitting. This ensures that the wire is kept taut during the slitting and conveying process, facilitating the slitting work.

[0026] In this embodiment, refer to Figure 3 As shown, the wire adjustment mechanism 2 also includes an adjustment seat 27, an adjustment roller 28, and an adjustment screw 29. The adjustment seat 27 is provided with an adjustment groove 290. The adjustment screw 29 is vertically threaded onto the adjustment seat 27. The adjustment roller 28 is provided with a wheel seat 291. The top of the wheel seat 291 is rotatably connected to the bottom of the adjustment screw 29. The wheel seat 291 slides up and down within the adjustment groove 290.

[0027] The operator rotates the vertically mounted adjusting screw 29. Because the adjusting screw 29 is threadedly connected to the adjusting seat 27, the rotational motion is converted into the up-and-down linear motion of the adjusting screw 29. This causes the wheel seat 291, which is rotatably connected at the bottom, to slide up and down along the adjusting groove 290. The adjusting roller 28 on the wheel seat 291 rises and falls synchronously. By changing the height of the adjusting roller 28, the tension of the wire is finely adjusted and the height is calibrated in the vertical direction. This eliminates the problem of slack or overstretching of the wire caused by the deviation in the unwinding height, so that the wire enters the subsequent conveying stage in a flat, straight and stable tension state.

[0028] In this embodiment, refer to Figure 4 As shown, the wire conveying protection mechanism 3 includes a conveying base 31, an upper conveying roller 32, a lower conveying roller 33, and a conveying motor 34. The conveying base 31 is provided with a conveying groove 35. Sliding blocks 36 are respectively provided at both ends of the upper conveying roller 32. The side wall of the conveying base 31 is provided with a sliding groove 37 for the sliding blocks 36 to slide. The lower conveying roller 33 is horizontally rotatably connected within the conveying base 31 and is arranged parallel to the upper conveying roller 32. The conveying motor 34 is located on the conveying base 31 and is drively connected to the lower conveying roller 33. Two adjusting electric cylinders 38 are provided on the top of the conveying base 31. The telescopic ends of the two adjusting electric cylinders 38 are respectively connected to the tops of the two sliding blocks 36. A cam 321 is provided on the upper conveying roller 32, and a groove 331 is provided on the lower conveying roller 33 that slides with the cam 321.

[0029] After the conveyor motor 34 starts, the lower conveyor roller 33 rotates at a set speed to provide power for the wire conveying. The wire moves in the groove 331 on the lower conveyor roller 33. By adjusting the extension and retraction of the electric cylinder 38, the sliding block 36 can be driven to slide up and down along the slide groove 37, thereby adjusting the distance between the upper conveyor roller 32 and the lower conveyor roller 33, and thus adjusting the distance between the cam 321 and the groove 331. After setting an appropriate distance according to the wire diameter, the upper conveyor roller 32 and the lower conveyor roller 33 form a clamping structure for the wire, applying a stable clamping force to the wire during the conveying process, and preventing the wire from shifting or jumping due to fluctuations in the conveying speed or external interference.

[0030] During the wire conveying process, the position of the upper conveying roller 32 is adjusted by adjusting the operation of the electric cylinder 38, so that the distance between the upper conveying roller 32 and the lower conveying roller 33 is suitable for the wire to be conveyed forward.

[0031] When the wire is conveyed and cut, the electric cylinder 38 is adjusted to move the position of the upper conveyor roller 32 downward, so that the upper conveyor roller 32 is close to the lower conveyor roller 33. The wire is clamped between the cam 321 on the upper conveyor roller 32 and the groove 331 on the lower conveyor roller 33. Through the continuous clamping of the upper conveyor roller 32 and the lower conveyor roller 33, a stable intermediate constraint is provided for the wire before cutting. Even if one end of the wire loses tension at the moment of cutting, the clamping force of the conveyor roller can still limit the release speed of the wire's elasticity, avoid high-speed flying, and fundamentally reduce the risk of personal injury to operators and damage to surrounding equipment.

[0032] In this embodiment, refer to Figure 5As shown, the wire slitting mechanism 4 includes a slitting seat 41 disposed beside the conveyor seat 31. The slitting seat 41 is provided with a slitting groove 42. A slitting base 43 is disposed in the slitting groove 42. A slitting blade groove 44 is disposed on the slitting base 43. A slitting cylinder 45 is disposed on the top of the slitting seat 41. A slitting blade 46 is disposed on the telescopic end of the slitting cylinder 45.

[0033] When the wire is being cut, the cutting cylinder 45 drives the cutting blade 46 to move downward, which works in conjunction with the cutting groove 44 to cut the wire.

[0034] In this embodiment, the adjusting groove 290, the conveying groove 35, and the slitting groove 42 are connected in a straight line. During the wire slitting process, the wire moves forward by passing through the adjusting groove 290, the conveying groove 35, and the slitting groove 42 in sequence, and the wire is slitted.
