Description

Technical Field

[0001] This utility model relates to the field of steel wire drawing technology, specifically to high-precision drawing equipment for ultra-fine steel wires. Background Technology

[0002] Wire drawing is a common process in metal processing. It involves stretching a metal blank to reduce its cross-sectional area and increase its length, ultimately producing a steel wire.

[0003] Application No. CN202020466523.6 discloses a high-precision metal wire drawing device. This utility model uses the cooperation of a cylinder, a moving plate, a fixed column, a spring, a pressure block, and a slot to facilitate the user to adjust the tension of the steel wire, thereby returning the steel wire to a taut state and preventing the steel wire from detaching from the surface of the guide wheel, which would reduce the wire drawing accuracy of the metal wire drawing device. This solves the problem of low wire drawing accuracy in traditional metal wire drawing devices.

[0004] The equipment adjusts the height of the pressure block according to the looseness or tightness of the steel wire, thereby adjusting the tension of the steel wire. However, it requires the operator to constantly observe the tension of the steel wire to start the cylinder, which increases labor costs. It is also prone to adjustment delays due to visual fatigue or distraction. Furthermore, when the steel wire is in the slot, it is easy to fall out of the slot when the steel wire is loose, requiring manual readjustment and repositioning. Therefore, a high-precision wire drawing device for ultra-fine steel wire is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a high-precision wire drawing device for ultra-fine steel wires.

[0006] The technical solution adopted by this utility model to solve its technical problem is a high-precision wire drawing device for ultra-fine steel wire, including a pressure block. The pressure block has a through groove inside for feeding steel wire. A movable block is movably inserted into the top of the through groove. The pressure block has a cavity inside, and the top of the movable block is located inside the cavity.

[0007] The bottom surface of the cavity is provided with a second pressure sensor, and a first pressure sensor is provided directly above the second pressure sensor. The top of the movable block is located between the first pressure sensor and the second pressure sensor. The first pressure sensor is fixedly installed at the bottom of the threaded rod, and the threaded rod is installed at the top of the pressure block by threads.

[0008] By adopting the above technical solution and using the coordinated control of dual pressure sensors and photoelectric sensors, the adaptive adjustment of steel wire tension is achieved. The displacement direction of the moving block is detected by the first and second pressure sensors respectively, and the height of the pressure block is dynamically adjusted by the cylinder to ensure that the steel wire is always taut. The precise alignment function of the photoelectric transmitter and receiver forms a closed-loop feedback, which enables the cylinder to respond quickly to tension changes and effectively prevent the steel wire from slack or overload breakage. This design significantly improves the stability and safety of the steel wire traction process and reduces the need for manual intervention.

[0009] Specifically, the top center of the movable block is fixedly connected to the bottom end of the guide rod, the guide rod is installed through the top of the pressure block, and a spring is sleeved on the outside of the guide rod.

[0010] Specifically, the bottom end of the spring is fixedly connected to the top end of the movable block, and the top end of the spring is fixedly connected to the upper inner part of the cavity.

[0011] By adopting the above technical solution, the guide rod provides vertical guidance for the up and down movement of the movable block, avoiding skewing. When the steel wire is relaxed, the preload of the spring pushes the movable block down, ensuring that the rubber pad at its bottom always fits against the inner bottom of the through groove, thus confining the steel wire in the limiting groove. When the steel wire is too tight, the reaction force of the steel wire overcomes the spring force, causing the movable block to move up, thereby triggering the first pressure sensor and starting the cylinder to retract the pressure block to release the tension.

[0012] Specifically, a photoelectric transmitter is fixedly installed on the upper part of one side of the movable block, and a photoelectric receiver is fixedly installed on one side of the cavity. The photoelectric transmitter and the photoelectric receiver are compatible.

[0013] By adopting the above technical solution, when the movable block moves up and down with the change of steel wire tension, the relative position of the photoelectric transmitter and the photoelectric receiver changes. When the movable block is in the ideal tension position (i.e. the steel wire is taut but not too tight), the light path of the photoelectric transmitter is aligned with the photoelectric receiver, and the trigger signal makes the cylinder stop moving.

[0014] Specifically, a limiting groove is provided at the bottom of the movable block, and a guide roller is rotatably installed inside the limiting groove. Bearings are sleeved at both ends of the guide roller, and the bearings are located inside the movable block. A rubber pad is fixedly attached to the bottom of the movable block.

[0015] By adopting the above technical solution, when the steel wire passes through the limiting groove, the guide roller rotates freely through the bearing, reducing the frictional resistance when the steel wire moves.

[0016] Specifically, the top of the movable block is fixedly connected to the cylinder output end inside the fixed box. The fixed box is fixedly installed on one side of the mounting plate. A guide wheel is rotatably installed on one side of the mounting plate, and a steel wire is connected to the surface of the guide wheel.

[0017] By adopting the above technical solution, during initial installation, the steel wire rests on the guide wheel and passes through the through groove, eventually connecting to the traction mechanism.

[0018] The beneficial effects of this utility model are:

[0019] The high-precision wire drawing equipment for ultra-fine steel wire described in this utility model adopts the coordinated control of dual pressure sensors and photoelectric sensors to achieve adaptive adjustment of steel wire tension. The displacement direction of the moving block is detected by the first and second pressure sensors respectively, and the height of the pressure block is dynamically adjusted by the cylinder to ensure that the steel wire is always taut. The precise alignment function of the photoelectric transmitter and receiver forms a closed-loop feedback, which enables the cylinder to respond quickly to tension changes and effectively prevent the steel wire from slack or breaking due to overload. This design significantly improves the stability and safety of the steel wire drawing process and reduces the need for manual intervention. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-3 As shown, the high-precision wire drawing equipment for ultra-fine steel wire of this utility model includes a pressure block 3, a through groove 4 is provided inside the pressure block 3 for supplying steel wire 1, a movable block 13 is movably inserted into the top of the through groove 4, a cavity 15 is provided inside the pressure block 3, and the top of the movable block 13 is located inside the cavity 15.

[0027] The bottom surface of the cavity 15 is provided with a second pressure sensor 11, and a first pressure sensor 8 is provided directly above the second pressure sensor 11. The top of the movable block 13 is located between the first pressure sensor 8 and the second pressure sensor 11. The first pressure sensor 8 is fixedly installed at the bottom of the threaded rod 10, and the threaded rod 10 is installed at the top of the pressure block 3 by threads.

[0028] When the steel wire 1 passes through the through groove 4 and is connected to the traction machine, the first pressure sensor 8 and the second pressure sensor 11 are energized. At this time, the second pressure sensor 11 triggers the cylinder to drive the pressure block 3 to move down until the steel wire 1 is pressed. When the steel wire 1 moves up and down due to the change of traction force, the first pressure sensor 8 and the second pressure sensor 11 respectively detect the displacement direction of the movable block 13 and adjust the height of the pressure block 3 through the signal control cylinder, thereby dynamically maintaining the tension balance of the steel wire 1.

[0029] It should be noted that the height of the first pressure sensor 8 in the cavity 15 can be adjusted by turning the threaded rod 10, thereby adjusting the upper limit height of the movable block 13 when the steel wire 1 is too tight.

[0030] The present invention also includes that the top center of the movable block 13 is fixedly connected to the bottom end of the guide rod 9, the guide rod 9 is installed through the top of the pressure block 3, and a spring 14 is sleeved on the outside of the guide rod 9.

[0031] The present invention also includes that the bottom end of the spring 14 is fixedly connected to the top end of the movable block 13, and the top end of the spring 14 is fixedly connected to the upper inner part of the cavity 15.

[0032] In use, the guide rod 9 provides vertical guidance for the up and down movement of the movable block 13 to avoid skewing. When the steel wire 1 is relaxed, the preload of the spring 14 pushes the movable block 13 down to ensure that the rubber pad 12 at its bottom end always fits against the inner bottom of the through groove 4, thus restricting the steel wire 1 in the limiting groove 17. When the steel wire 1 is too tight, the reaction force of the steel wire 1 overcomes the elastic force of the spring 14, causing the movable block 13 to move up, thereby triggering the first pressure sensor 8 and starting the cylinder to retract the pressure block 3 to release the tension.

[0033] The present invention also includes a photoelectric transmitter 16 fixedly installed on the upper part of one side of the movable block 13, and a photoelectric receiver 7 fixedly installed on one side of the cavity 15, wherein the photoelectric transmitter 16 and the photoelectric receiver 7 are adapted to each other.

[0034] When in use, as the movable block 13 moves up and down with the change in tension of the steel wire 1, the relative position of the photoelectric transmitter 16 and the photoelectric receiver 7 changes. When the movable block 13 is in the ideal tension position (i.e. the steel wire 1 is taut but not too tight), the light path of the photoelectric transmitter 16 is aligned with the photoelectric receiver 7, and the trigger signal causes the cylinder to stop moving.

[0035] The present invention further includes a limiting groove 17 at the bottom end of the movable block 13, a guide roller 18 rotatably mounted inside the limiting groove 17, bearings 19 sleeved at both ends of the guide roller 18, the bearings 19 being located inside the movable block 13, and a rubber pad 12 being fixedly attached to the bottom end of the movable block 13.

[0036] When in use, when the steel wire 1 passes through the limiting groove 17, the guide roller 18 rotates freely through the bearing 19, reducing the frictional resistance when the steel wire 1 moves.

[0037] The present invention also includes that the top end of the movable block 13 is fixedly connected to the cylinder output end inside the fixed box 5, the fixed box 5 is fixedly installed on one side of the mounting plate 6, a guide wheel 2 is rotatably installed on one side of the mounting plate 6, and a steel wire 1 is connected to the surface of the guide wheel 2.

[0038] During use, during initial installation, the steel wire 1 rests on the guide wheel 2 and passes through the through groove 4, eventually connecting to the traction mechanism.

[0039] In use, the steel wire 1 is first placed on the guide wheel 2 and passed through the limiting groove 17 of the movable block 13 in the through groove 4. Then it is placed on another guide wheel 2 and finally connected to the traction mechanism. At this time, the first pressure sensor 8 and the second pressure sensor 11 are energized. Since the movable block 13 in the initial state is in direct contact with the second pressure sensor 11 and applies downward pressure, the second pressure sensor 11 sends a start signal to the cylinder in the fixed box 5. The cylinder starts, causing the pressure block 3 to move downwards slowly until the steel wire 1 is pressed to a taut state. At this taut state, the steel wire 1 will contact the guide roller 18 and slightly move the guide roller 18 and the movable block 13 upwards a short distance. The photoelectric transmitter 16 on one side of the movable block 13 will align with the photoelectric receiver 7. After receiving the light signal, the receiver 7 sends a stop signal to the cylinder inside the fixed box 5, keeping the steel wire 1 taut and preventing it from detaching from the surface of the guide wheel 2. When the steel wire 1 is too taut, it will drive the movable block 13 to move upward continuously until the movable block 13 contacts the first pressure sensor 8 and applies upward pressure to the first pressure sensor 8. At this time, the first pressure sensor 8 sends a start signal to the cylinder inside the fixed box 5. The cylinder starts and drives the pressure block 3 to move upward slowly. As the pressure block moves upward, the spring 14 pushes the movable block 13 downward until the steel wire 1 returns to its initial taut state. When the movable block 13 moves downward to the position where the photoelectric transmitter 16 and the photoelectric receiver 7 are aligned, the photoelectric receiver 7 receives the light signal and sends a stop signal to the cylinder inside the fixed box 5, thereby stopping the upward movement of the pressure block 3.
