Description

Technical Field

[0001] This utility model relates to a wire cutting device, and more particularly to a wire cutting machine for power cord production. Background Technology

[0002] Power cords require wire cutting during production to be cut to the length of the finished product, necessitating the use of wire cutting equipment. Since the wire cutting process typically employs a shearing mechanism, the wire to be cut cannot be continuously fed during cutting, often requiring intermittent feeding. This intermittent feeding method not only affects cutting efficiency but also causes significant load variations in related components when switching between start-up and stop states, thus substantially impacting the equipment's lifespan and leading to a higher frequency of maintenance or replacement of related parts. Summary of the Invention

[0003] This utility model provides a wire cutting machine for power cord production; it solves the problem in the prior art where the intermittent wire feeding operation of the wire cutting equipment affects the cutting efficiency and equipment life.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a wire cutting machine for power cord production, including a base, a first positioning plate and a second positioning plate vertically fixed on the base, a first horizontally arranged lead tube fixed on the first positioning plate, and a second horizontally arranged lead tube fixed on the second positioning plate; a sliding seat is also provided between the two positioning plates, which is slidably engaged with the base, and a linear slide table is provided on the base to drive the sliding seat to move back and forth; a third lead tube is fixed on the sliding seat, the three lead tubes are coaxially arranged, a lower blade and a shearing cylinder are also fixed on the sliding seat, an upper blade is fixed on the telescopic rod of the shearing cylinder, the upper blade and the lower blade can produce a shearing action, and the shearing position is located in the outlet area of ​​the third lead tube; a traction wheel set is provided on the front side of the first positioning plate and the rear side of the second positioning plate, the traction wheel set including a bracket and two power wheels that rotate in opposite directions at the same speed.

[0005] The wire to be cut is introduced through the traction wheel assembly on the front side of the first positioning plate, passing sequentially through the first lead tube, the third lead tube, and the second lead tube. The upper and lower blades are positioned between the third and second lead tubes. When the present invention is to perform the wire cutting action, the linear slide table first drives the sliding seat to move, with the moving direction and speed consistent with the wire to be cut. Then, the cutting cylinder pushes the upper blade downward to achieve wire cutting. After the wire cutting is completed, the cutting cylinder pulls the upper blade upward to reset, and the sliding seat continues to move towards the second positioning plate until... As the third lead tube approaches the second lead tube, and the sliding seat stops, the third lead tube stops moving. The cut wire moves backward under the traction of the traction wheel set behind the second positioning plate. The wire to be cut also continues to be conveyed backward. Since the end of the wire to be cut is close to the opening of the second lead tube, and the wire itself has a certain stiffness, the wire can be smoothly inserted into the second lead tube and conveyed backward along with the cut wire. After the sliding seat pauses briefly, the linear slide will push the sliding seat back to its original position, waiting for the next wire cutting.

[0006] Furthermore, the lower blade has a recessed cutting edge on its upper side, and the upper blade has an upward-recessed cutting edge on its lower side. This design minimizes deformation of the wire's cutting surface, preserving the wire's original contour as much as possible.

[0007] Furthermore, the front end of the second lead tube is provided with a funnel-shaped opening. The funnel-shaped opening at the front end of the second lead tube is relatively large compared to its own inner cavity opening, which can greatly increase the probability of the wire being inserted into the second lead tube even if the wire is bent or deformed.

[0008] Furthermore, proximity sensors for detecting the position of the sliding block are provided on the rear side of the first positioning plate and the front side of the second positioning plate. When either proximity sensor detects the sliding block approaching, the linear slide will stop under control. Although the linear slide can be programmed to stop at a fixed point, there is a possibility of program failure. By setting proximity sensors, the uncontrolled movement of the sliding block can be avoided.

[0009] Therefore, this utility model has the following characteristics compared with the prior art: 1. In the cutting process, since the sliding seat can move synchronously with the wire, the wire can be continuously conveyed during the cutting process, which can effectively improve the cutting efficiency and avoid excessive load changes due to repeated start-stop of the equipment, which is conducive to extending the equipment life and reducing the maintenance frequency.

[0016] Example 1: See Figure 1 A wire cutting machine for power cord production includes a base 10, a first positioning plate 11 and a second positioning plate 12 vertically fixed on the base, a first lead tube 21 horizontally fixed on the first positioning plate, and a second lead tube 22 horizontally fixed on the second positioning plate. The first and second lead tubes are respectively provided with a first flange 211 and a second flange 221 for fixed connection. Two guide rods 13 are also horizontally parallel between the two positioning plates, each guide rod having a sliding sleeve 14 slidably fitted on it. A sliding seat 30 is fixedly connected between the two sliding sleeves (see...). Figure 3 The base is equipped with a linear slide 40 that can drive the sliding seat to move back and forth; a third lead tube 23 is fixed on the sliding seat, the three lead tubes are coaxially arranged, a lower blade 50 and a shearing cylinder 60 are also fixed on the sliding seat, an upper blade 70 is fixed on the telescopic rod of the shearing cylinder, the upper blade and the lower blade can produce a shearing action, the shearing position is located in the outlet area of ​​the third lead tube; a traction wheel set 80 is provided on the front side of the first positioning plate and the rear side of the second positioning plate, the traction wheel set includes a bracket 81 and two power wheels 82 that rotate in opposite directions at the same speed, and an annular wire groove 83 is formed on the circumferential side wall of the power wheel (see Figure 2 ).

[0017] The wire to be cut 1 is introduced from the traction wheel assembly on the front side of the first positioning plate, and passes sequentially through the first lead tube, the third lead tube, and the second lead tube. The upper blade and the lower blade are located between the third lead tube and the second lead tube. When the wire cutting action is to be performed in this embodiment, the linear slide will first drive the sliding seat to move, and the moving direction and speed are consistent with the wire to be cut. Then, the cutting cylinder pushes the upper blade downward to achieve wire cutting. After the wire cutting is completed, the cutting cylinder pulls the upper blade upward to reset, and the sliding seat continues to move towards the side of the second positioning plate until... As the third lead tube approaches the second lead tube, and the sliding seat stops, the third lead tube stops moving. The cut wire moves backward under the traction of the traction wheel set behind the second positioning plate. The wire to be cut also continues to be conveyed backward. Since the end of the wire to be cut is close to the opening of the second lead tube, and the wire itself has a certain stiffness, the wire can be smoothly inserted into the second lead tube and conveyed backward along with the cut wire. After the sliding seat pauses briefly, the linear slide will push the sliding seat back to its original position, waiting for the next wire cutting.

[0018] See Figure 1 The upper blade is vertically arranged and is attached to the rear side of the upper blade. The sliding seat is provided with a limiting block 31 that slides and attaches to the rear side of the upper blade. A blade holder 71 is mounted on the upper side of the upper blade and is connected and fixed to the telescopic rod of the shearing cylinder.

[0019] See Figure 4 The lower blade has a recessed lower cutting edge 51 on its upper side, and the upper blade has a recessed upper cutting edge 72 on its lower side. This design minimizes deformation of the wire's cutting surface and preserves the wire's original contour as much as possible.

[0020] See Figure 1 The front end of the second lead tube is provided with a funnel-shaped opening 222. The funnel-shaped opening at the front end of the second lead tube is relatively large compared to its own inner cavity opening, so even if the wire has some bending deformation, the probability of the wire being inserted into the second lead tube can be greatly increased.

[0021] See Figure 1 The bottom of the sliding seat is provided with a lever 32, and the linear slide is provided with two push blocks 41 that fit against the front and rear sides of the lever.

[0022] See Figure 1 The linear slide is equipped with proximity sensors 90 on the rear side of the first positioning plate and the front side of the second positioning plate for detecting the position of the sliding block. When either proximity sensor detects that the sliding block is approaching, the linear slide will stop under control. Although the linear slide can be programmed to stop at a fixed point, there is a possibility of program failure. By setting proximity sensors, the situation of uncontrolled movement of the sliding block can be avoided.

All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
