Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically relating to a semi-steel cable cutting mechanism. Background Technology

[0002] Currently, in the production process of semi-steel cables, they need to be cut to meet customers' requirements for different cable lengths. The traditional cutting method is manual, where an operator holds the cable by hand and places it into a cutting machine. This is not only time-consuming and labor-intensive, but also inefficient, produces uneven cuts, and is highly dangerous and unsafe. Therefore, a semi-steel cable cutting mechanism has been designed to solve these problems.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a semi-steel cable cutting mechanism.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a semi-steel cable cutting mechanism, comprising: a housing, wherein an installation base plate is provided inside the housing; a limiting unit, wherein the limiting unit is movable back and forth and is disposed above the housing to limit the length of the cable being cut; a cutting unit, wherein the cutting unit is disposed inside the housing, the cutting unit including a saw blade that can move left and right, the saw blade being connected to a drive motor, the upper end of the saw blade extending beyond the upper end surface of the housing; and a positioning unit, wherein the positioning unit is disposed above the saw blade and in front of the limiting unit, the positioning unit including a positioning block, the positioning block being located above the housing, the positioning block being provided with a cutting groove through which the saw blade can pass.

[0006] Furthermore, the limiting unit includes a mounting block, which is disposed on a first guide rail. The first guide rail is fixed to the upper end face of the housing, and a rotatable baffle is provided at the end of the mounting block. In this design, the first guide rail is disposed on the housing along the front-to-back direction (the length direction of the housing). When the cable needs to be cut, the baffle is manually rotated to a position that can hold the cable in place, thereby limiting its movement.

[0007] Furthermore, the baffle includes a first baffle and a second baffle. The first baffle is located at the front end of the mounting block, and the second baffle is located at the rear end of the mounting block. The area of ​​the first baffle is larger than the area of ​​the second baffle. In this solution, the first and second baffles can be used to limit cables of different shapes.

[0008] Furthermore, the mounting block has a threaded hole at its top, and a rotatable bolt is installed in the threaded hole. The lower end of the bolt can abut against the upper end of the housing. In this design, the bolt on the mounting block serves a locking function. After the mounting block moves to the desired position on the first guide rail, the bolt is rotated so that its bottom abuts against the housing, locking the mounting block onto the first guide rail. The locking force is sufficient to keep it stationary when the cable cutting length is limited.

[0009] Furthermore, the saw blade is connected to a main shaft, which is connected to a drive motor via a belt drive. Both the main shaft and the drive motor are mounted on a mounting plate, which is mounted on a second guide rail, which is fixed to the mounting base plate. In this design, the saw blade is driven to rotate by the drive motor and moves via the mounting base plate on the second guide rail, thus enabling the saw blade to move and cut the semi-steel cable.

[0010] Furthermore, a wheel is provided on one side of the mounting plate, the center of which is connected to the shaft of a reduction motor, which is fixed to the mounting base plate. A connector is fixed on the wheel, offset from the center of the wheel, and connected to the mounting plate via a movable joint. A mating seat is fixed on the mounting plate, and the two ends of the movable joint are rotatably connected to the mating seat and the connector, respectively. In this design, the reduction motor drives the wheel to rotate. Because the connector is offset from the center of the wheel, when the wheel rotates, the movable joint moves with the connector, causing the mounting plate to reciprocate on the second guide rail, thereby achieving left-right position adjustment of the saw blade.

[0011] Furthermore, the positioning block includes a left positioning block and a right positioning block. The lower ends of both the left and right positioning blocks have cutting grooves that allow the upper end of the saw blade to move back and forth. The right side of the left positioning block has a notch. The left and right positioning blocks are arranged side-by-side and form the tangential groove through the notch. In this design, the left and right positioning blocks together form the tangential groove. The cable is placed into the tangential groove, and the saw blade cuts the cable by moving within the groove.

[0012] Furthermore, the right positioning block has a movable stop block inside, which is mounted on a support frame. The support frame is connected to the mounting plate. A spring is installed between the stop block and the support frame, and the stop block moves in and out of the cutting groove via the spring. In this design, the stop block can be used to hold the cable to be cut, and the spring force can hold the cable in place to prevent it from tilting during cutting, thus solving the safety problem caused by manually cutting cables.

[0013] Furthermore, a proximity switch is provided on one side of the support frame, and the proximity switch is fixed to the housing by a bracket. In this design, providing a proximity switch on one side of the support frame facilitates the detection of distance changes and the control of the saw blade's movement distance.

[0014] Furthermore, an observation port is provided on the front side of the housing, and a transparent plate is installed at the observation port. In this design, the observation port with a transparent plate is provided on the housing to facilitate safe observation.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] The semi-steel cable cutting mechanism designed in this utility model can control the cable cutting length through a limiting structure. The mechanism uses an electric saw blade for precise cutting, which is highly efficient and ensures good cable length consistency. Operators only need to place the cable to be cut into the corresponding cutting groove without directly contacting the electric saw blade, making it convenient to operate and safe.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] Example:

[0029] This embodiment provides a semi-steel cable cutting mechanism, including: a housing 1, see attached... Figure 1 As shown, a mounting base plate 2 is provided inside the housing 1; an observation port 6 is provided on the front side of the housing 1, and a transparent plate is provided at the observation port 6. The housing 1 is designed to prevent personnel from contacting the cutting center, thus improving cutting safety. The observation port 6 with a transparent plate on the housing 1 facilitates safe observation.

[0030] Limiting unit 3, see appendix Figure 1 and attached Figure 5As shown, the limiting unit 3 is movable and positioned above the housing 1 to limit the length of the cable being cut. The limiting unit 3 includes a mounting block 301, which is mounted on a first guide rail 302. The first guide rail 302 is fixed to the upper surface of the housing 1, and a rotatable baffle is provided at the end of the mounting block 301. The first guide rail 302 is positioned on the housing 1 along the front-to-back direction (the length direction of the housing 1). When the cable needs to be cut, the baffle is manually rotated to a position that can hold the cable in place, thus limiting its movement. The baffle includes a first baffle 303 and a second baffle 304. The first baffle 303 is located at the front end of the mounting block 301, and the second baffle 304 is located at the rear end of the mounting block 301. The area of ​​the first baffle 303 is larger than the area of ​​the second baffle 304. The first baffle 303 and the second baffle 304 are designed to limit cables of different shapes. For example, the larger first baffle 303 can limit the cable to be cut when bent, while the smaller second baffle 304 can limit the cable to be cut when straight. The top of the mounting block 301 has a threaded hole, in which a rotatable bolt 305 is installed. The lower end of the bolt 305 abuts against the upper end of the housing 1. The bolt 305 on the mounting block 301 serves a locking function. After the mounting block 301 moves to the desired position on the first guide rail 302, rotating the bolt 305 causes its bottom to abut against the housing 1, locking the mounting block 301 onto the first guide rail 302. The locking force is sufficient to limit the cable cutting length and keep it stationary.

[0031] Cutting unit 4, see appendix Figure 2 and attached Figure 3As shown, the cutting unit 4 is disposed inside the housing 1. The cutting unit 4 includes a saw blade 401 that can move left and right. The saw blade 401 is connected to a drive motor 402, and the upper end of the saw blade 401 extends out of the upper end surface of the housing 1. The saw blade 401 is connected to a spindle 403, and the spindle 403 is connected to the drive motor 402 via a belt 404. Both the spindle 403 and the drive motor 402 are mounted on a mounting plate 405, which is mounted on a second guide rail 406. The second guide rail 406 is fixed to the mounting base plate 2. The saw blade 401 is driven to rotate by the drive motor 402 and moves along the second guide rail 406 via the mounting base plate 2, thereby realizing the moving cutting of the semi-steel cable by the saw blade 401. The drive motor 402 is a high-speed permanent magnet motor. The second guide rail 406 is arranged in the left-right direction. The spindle 403 is enabled by a cut-off mechanism, which acts as a protective mechanism. In case of emergency during machining, the spindle 403's rotation can be quickly stopped to ensure the safety of the workpiece and equipment. A wheel 407 is mounted on one side of the mounting plate 405. The center of the wheel 407 is connected to the shaft of the geared motor 408, which is fixed to the mounting base plate 2. A connector 409 is fixed to the wheel 407, offset from the center of the wheel 407. The connector 409 is connected to the mounting plate 405 via a movable joint 410. A mating seat 411 is fixed to the mounting plate 405. The two ends of the movable joint 410 are rotatably connected to the mating seat 411 and the connector 409, respectively. The movable joint 410 is a fisheye joint. The geared motor 408 drives the wheel 407 to rotate. Since the connecting piece 409 is offset from the center of the wheel 407, when the wheel 407 rotates, the movable joint 410 drives the mounting plate 405 to reciprocate on the second guide rail 406 along with the movement of the connecting piece 409, thereby realizing the position adjustment of the saw blade 401 in the left and right directions.

[0032] Positioning unit 5, see appendix Figure 3 and attached Figure 4As shown, the positioning unit 5 is located at the upper end of the saw blade 401 and in front of the limiting unit 3. The positioning unit 5 includes a positioning block located above the housing 1. The positioning block has a cutting groove 501 through which the saw blade 401 can pass. The positioning block includes a left positioning block 502 and a right positioning block 503. The lower ends of both the left and right positioning blocks 502 and 503 have cutting grooves 504 that allow the upper end of the saw blade 401 to move back and forth. The right side of the left positioning block 502 has a notch. The left and right positioning blocks 502 and 503 are arranged side by side and form the cutting groove 501 through the notch. The left and right positioning blocks 502 and 503 together form the cutting groove 501. When a cable is placed in the cutting groove 501, the saw blade 401 cuts the cable by moving within the cutting groove 504. The right positioning block 503 has a movable stop block 505 inside, which is mounted on a support frame 506. The support frame 506 is connected to the mounting plate 405. A spring 507 is installed between the stop block 505 and the support frame 506, and the stop block 505 moves in and out of the cutting groove 501 via the spring 507. The stop block 505 can be used to hold the cable to be cut, and the spring 507 can forcefully hold the cable to prevent it from tilting during cutting, thus solving the safety problem caused by manually cutting the cable. A proximity switch 508 is installed on one side of the support frame 506, and the proximity switch 508 is fixed to the housing 1 by a bracket. The proximity switch 508 is installed on one side of the support frame 506 to facilitate the detection of distance changes and the control of the movement distance of the saw blade 401.

[0033] Working principle: According to the cable length limit requirement, the operator moves the mounting block 301 of the limiting unit 3 to a suitable position on the first guide rail 302, and locks the mounting block 301 to the housing 1 with bolts 305; then the operator puts the cable to be cut into the cutting groove 501 and moves the cable forward so that it abuts against the corresponding baffle; the abutment block 505 in the positioning unit 5 will abut against the cable under the action of the spring 507 to prevent it from moving; start the cutting equipment, the saw blade 401 moves in the cutting groove 504 and cuts the cable, and then repeat the above process.

[0034] The semi-steel cable cutting mechanism designed in this utility model can control the cable cutting length through the limiting structure. The mechanism uses an electric saw blade 401 for precise cutting, which has high cutting efficiency and good cable length consistency.
