Description
A tension equalization guide device Technical Field
[0001] This utility model relates to the field of wire drawing technology, and in particular to a drawing tension equalization guiding device. Background Technology
[0002] A tension balancing guide device is a piece of equipment used in the wire drawing process. It primarily ensures that the wire maintains stable tension during drawing and guides the wire along a predetermined path to improve drawing quality and production efficiency. It has the following structure:
[0003] 1. Bracket: As the basic support structure of the entire device, it provides installation positions for components such as pressure sensors, adjusting wheels, guide wheels, and protective covers. The bracket is installed on the wire drawing equipment.
[0004] 2. Pressure sensor: Real-time sensing of the force exerted by the wire on the guide wheel or adjusting wheel during the drawing process, and converting the force signal into an electrical signal output. By detecting changes in force, the magnitude of the drawing tension is fed back.
[0005] 3. Adjusting wheel: During the drawing process, the adjusting wheel changes the running path and angle of the wire by rotating. When the pressure sensor detects abnormal tension, the adjusting wheel can adjust its position or angle under the control of the control device, thereby changing the tension on the wire.
[0006] 4. Guide wheel: Guides the wire to travel along the predetermined path, preventing the wire from deviating or causing unnecessary interference with other components;
[0007] 5. Tension control device: Receives the electrical signal output from the pressure sensor, analyzes and processes the signal, and realizes real-time control of the drawing tension.
[0008] The sensing surface of the pressure sensor contacts the force point of the adjusting wheel. When the adjusting wheel is subjected to axial or radial force by the tension of the wire, the shaft undergoes a slight deformation, and the resistance value of the strain gauge changes, thereby detecting the magnitude of the force. When metal debris in the workshop collides and impacts the pressure sensor instantaneously, it will interfere with the process of converting the force signal into an electrical signal, causing abnormal fluctuations in the measurement data. This will affect the accuracy of the pressure sensor in detecting the tension of the adjusting wheel, reduce the real-time control effect of the pulling tension, and consequently lead to quality defects such as wire breakage, surface scratches, and dimensional deviations. Summary of the Invention
[0009] To address the shortcomings of existing technologies, this utility model provides a tension equalization guide device for drawing tension. This device solves the technical problem that when metal debris in the workshop collides and impacts with the pressure sensor, it interferes with the process of converting the force signal into an electrical signal, causing abnormal fluctuations in the measurement data. This affects the accuracy of the pressure sensor in detecting the tension of the adjusting wheel, reduces the real-time control effect of drawing tension, and ultimately leads to quality defects such as wire breakage, surface scratches, and dimensional deviations.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A tension equalization guide device includes a bracket, a pressure sensor, an adjusting wheel, and a guide wheel. The pressure sensor is mounted on the bracket. The adjusting wheel is rotatably connected to the outside of the bracket. The guide wheel is rotatably connected to the outside of the bracket. A protective cover for shielding the pressure sensor is provided on the outside of the bracket. A fixing mechanism for fixing the protective cover is provided on the outside of the bracket. The fixing mechanism includes a screw, a through hole, and a nut. The screw is located on the outside of the bracket. The through hole is opened on the outside of the protective cover. The protective cover is slidably connected to the outside of the screw through the through hole. The nut is threadedly connected to the outside of the screw and is used to limit the movement of the protective cover.
[0012] Preferably, a limiting block is provided on the outside of the bracket, and a screw is fixedly installed on the outside of the limiting block. A slot is opened inside the through hole, and the limiting block is engaged inside the slot to limit the rotation of the protective cover.
[0013] Preferably, the bracket has an external mounting hole, the limiting block is slidably connected inside the mounting hole, the limiting block has a limiting spring for limiting the movement of the limiting block, the limiting block has a deformation groove, and one end of the limiting spring is fixedly connected inside the deformation groove to facilitate the release of the limiting block.
[0014] Preferably, a guide plate is fixedly installed on the outside of the bracket, and a guide groove is opened on the outside of the guide plate. The protective cover is slidably connected inside the guide groove to prevent damage to the pressure sensor due to improper installation and operation, and to reduce the impact on the performance of the pressure sensor during the installation process.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The installation method of the screw and nut facilitates quick disassembly of the protective cover for sensor maintenance by operators. The protective cover covers the outside of the pressure sensor, forming a physical isolation barrier, effectively blocking the impact of metal debris, reducing the interference of external factors on the pressure sensor, ensuring the process of force signal conversion into electrical signal, reducing the risk of abnormal fluctuations in measurement data, thereby ensuring the detection accuracy of the pressure sensor on the tension of the adjusting wheel and the real-time control effect of the pulling tension, and thus ensuring product quality.
[0017] 2. Install the protective cover. The protective cover should first contact the inside of the guide groove. The guide groove restricts the position of the protective cover, thereby avoiding contact with the pressure sensor during the installation process. This prevents damage to the pressure sensor due to improper installation and reduces the impact on the performance of the pressure sensor during the installation process. Attached Figure Description

[0026] As shown in Figures 1, 2, 3, and 4, the technical solution in this embodiment effectively solves the problem that when metal debris in the workshop collides and impacts with the pressure sensor, it interferes with the process of converting the force signal into an electrical signal, causing abnormal fluctuations in the measurement data. This affects the pressure sensor's detection accuracy of the tension adjustment wheel, reduces the real-time control effect of the drawing tension, and ultimately leads to quality defects such as wire breakage, surface scratches, and dimensional deviations. The overall approach is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a tension equalization guiding device, including a bracket 1, a pressure sensor 2, an adjusting wheel 3, and a guide wheel 4. The pressure sensor 2 is mounted on the bracket 1, the adjusting wheel 3 is rotatably connected to the outside of the bracket 1, and the guide wheel 4 is rotatably connected to the outside of the bracket 1. A protective cover 5 for shielding the pressure sensor 2 is provided on the outside of the bracket 1, and a fixing mechanism for fixing the protective cover 5 is provided on the outside of the bracket 1. The fixing mechanism includes a screw 6, a through hole 7, and a nut 8. The screw 6 is located on the outside of the bracket 1, the through hole 7 is opened on the outside of the protective cover 5, the protective cover 5 is slidably connected to the outside of the screw 6 through the through hole 7, and the nut 8 is threadedly connected to the outside of the screw 6 and is used to restrict the movement of the protective cover 5.
[0028] The bracket 1 is provided with a limiting block 9 on the outside. The limiting block 9 is T-shaped. The screw 6 is fixedly installed on the outside of the limiting block 9. The through hole 7 is provided with a slot 10. The limiting block 9 is engaged in the slot 10 and used to limit the rotation of the protective cover 5.
[0029] The bracket 1 has an external mounting hole 11, and the limiting block 9 is slidably connected inside the mounting hole 11.
[0030] The limiting block 9 is provided with a limiting spring 12 for limiting the movement of the limiting block 9. The limiting block 9 is provided with a deformation groove 13. One end of the limiting spring 12 is fixedly connected to the inside of the deformation groove 13, and the other end extends outward.
[0031] A guide plate 14 is fixedly installed on the outside of the bracket 1. A guide groove 15 is opened on the outside of the guide plate 14. The protective cover 5 is slidably connected inside the guide groove 15.
[0032] Protective cover 5: Encloses the pressure sensor 2 to block external impacts, ensuring that the pressure sensor 2 can work stably, thereby ensuring the reliability of the entire tension equalization guide device.
[0033] Fixing mechanism: The protective cover 5 is fitted onto the screw 6 through the through hole 7, realizing the initial connection between the protective cover 5 and the bracket 1. The nut 8 is threaded onto the screw 6. After tightening the nut 8, the protective cover 5 can be firmly fixed on the bracket 1, restricting its movement. The detachable design facilitates the disassembly and assembly of the protective cover 5.
[0034] Limiting block 9 and slot 10: restrict the rotation of the protective cover 5 around the screw 6 to avoid affecting the protection effect on the pressure sensor 2 or interfering with other components due to the rotation of the protective cover 5;
[0035] Mounting hole 11: Provides space for the installation of the limit block 9, facilitating the installation and removal of the limit block 9;
[0036] Limiting spring 12 and deformation groove 13: When the limiting block 9 slides to a suitable position in the mounting hole 11, the limiting spring 12 undergoes a certain deformation.

[0037] Guide plate 14 and guide groove 15: Install protective cover 5. The protective cover 5 first contacts the inside of the guide groove 15. The guide groove 15 restricts the position of the protective cover 5, thereby avoiding contact with the pressure sensor 2 during the installation of the protective cover 5.
[0038] Working principle:
[0039] The pressure sensor 2, adjusting wheel 3, and guide wheel 4 are installed outside the bracket 1. The protective cover 5 is then placed over the pressure sensor 2 until the limit block 9 is engaged inside the slot 10. Simultaneously, the screw 6 passes through the through hole 7, and the nut 8 is threaded onto the outside of the screw 6. The protective cover 5 is now installed. During the drawing operation, as the wire moves under the drawing force, the guide wheel 4 guides the wire along a predetermined path. The wire exerts a force on the guide wheel 4 and adjusting wheel 3. The pressure sensor 2 senses this force in real time and converts it into an electrical signal, providing feedback on the drawing tension. If the tension is abnormal, the control system can drive the adjusting wheel 3 to adjust its position or angle based on the feedback signal from the pressure sensor 2, changing the tension on the wire to achieve equilibrium. Throughout this process, the protective cover 5 continuously functions, blocking external impacts and ensuring the stable operation of the pressure sensor 2, thereby guaranteeing the reliability of the entire drawing tension equalization guide device.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
