Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel wire, and in particular to a stainless steel wire drawing tension adjustment device. Background Technology

[0002] Stainless steel wire, also known as stainless steel cord, is a type of wire product made from stainless steel in various specifications and models. Its cross-section is generally round or flat. The main component of stainless steel wire is iron, and it also contains alloying elements such as chromium, nickel, and molybdenum. Chromium is a key element in the corrosion resistance of stainless steel, and its content is usually above 10.5%. It reacts with oxygen to form a dense oxide film on the surface of stainless steel, preventing further penetration of oxygen and moisture, thus achieving corrosion protection. Nickel can improve the corrosion resistance and mechanical properties of stainless steel, and its content is usually above 8%. Stainless steel wire possesses many excellent properties, such as outstanding corrosion resistance. Whether in harsh environments such as marine and chemical plants, or in ordinary humid or dry environments, stainless steel wire can maintain its surface smoothness and strength, and is not easily oxidized or corroded. At the same time, it also has high strength and hardness, as well as good high-temperature stability, and can maintain its strength and shape at temperatures up to 1500°C. Stainless steel wire drawing is a process in which the stainless steel wire undergoes plastic deformation through the stretching action of a die, thereby achieving changes in size and shape. If the drawing tension is unstable, it will cause uneven stress on the wire in the die, which will lead to deviations in the dimensional accuracy of the wire, such as diameter and roundness. Therefore, a stainless steel wire drawing tension adjustment device is particularly needed.

[0003] However, traditional stainless steel wire drawing tension adjustment devices have a low degree of automation, and most operations rely on manual intervention. Operators need to pay close attention to the drawing process and manually adjust the tension. This not only increases labor costs and labor intensity, but also makes it easy for adjustments to be untimely or inaccurate due to human negligence. At the same time, it is difficult to guarantee the consistency of manual operation. The tension adjusted by different operators may vary, affecting the stability and consistency of product quality. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel wire drawing tension adjustment device, which has the function of automatically adjusting the tension of stainless steel wire, and solves the problem of low automation in traditional stainless steel wire drawing tension adjustment devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel wire drawing tension adjustment device, comprising a base, a support plate connected to one end of the base, a push rod connected to one side of the support plate, a pulley installed at the bottom of the base, a transmission device provided above the base, and an adjustment mechanism also provided above the base;

Stainless steel wires are attached to the surfaces of both the unwinding drum and the winding drum. A fixing frame is also connected to the top of the base. A guide wheel is connected to the inner side of the fixing frame. A limit groove is formed on the surface of the guide wheel, and a tension sensor is provided above the guide wheel.

[0009] Preferably, the stainless steel wire on the surface of the unwinding drum is connected to the surface of the unwinding drum via a limiting groove, and the winding shaft cooperates with the winding drum through a drive motor to form a rotating structure.

[0012] Preferably, the size of the positioning block is adapted to the size of the positioning hole, and multiple sets of positioning holes are equally spaced on the inner side of the slide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This stainless steel wire drawing tension adjustment device, through the setting of the adjustment mechanism, realizes the automated and precise adjustment of the stainless steel wire drawing tension. The cooperation of the servo motor, threaded rod, and auxiliary rod replaces manual adjustment, reducing the error of the traditional method.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a stainless steel wire drawing tension adjustment device, including a base 1, a support plate 2 connected to one end of the base 1, a push rod 3 connected to one side of the support plate 2, a pulley 4 installed at the bottom of the base 1, a transmission device 5 provided above the base 1, and an adjustment mechanism 6 provided above the base 1.

[0022] The adjustment mechanism 6 includes a base plate 601, which is fixedly connected to the top of the base 1. A fixing rod 602 is connected to the top of the base plate 601. A groove 603 is formed on the inner wall surface of the fixing rod 602. A servo motor 604 is installed at the bottom of the groove 603. A threaded rod 605 is connected to the output end of the servo motor 604. An auxiliary rod 606 is fixedly connected inside the groove 603. A slider 607 is slidably connected to the surfaces of the threaded rod 605 and the auxiliary rod 606. A telescopic hole 608 is formed inside the slider 607. A telescopic spring 609 is connected to the inner end of the telescopic hole 608. The outer end of the slide 607 is connected to a limiting plate 610, and the outer end of the limiting plate 610 is connected to a positioning block 611. A positioning hole 612 is opened on the inner side of the slide groove 603. An adjusting rod 613 is connected to the surface of the slide 607, and a tension wheel 614 is set above the adjusting rod 613. Through the setting of the adjusting mechanism 6, when it is necessary to adjust the tension of the stainless steel wire drawing, the servo motor 604 in the adjusting mechanism 6 is started. The servo motor 604 is powered on and runs, and its output end drives the threaded rod 605 to rotate in the slide groove 603. Since the slide 607 is threadedly connected to the threaded rod 605, and the slide 607 is also sleeved on the auxiliary rod 606, the slide 607 is connected to the threaded rod 605. The auxiliary rod 606 acts as a guide, restricting the rotation of the slider 607. Therefore, the slider 607 slides up and down within the groove 603 along the axial direction of the threaded rod 605 and the auxiliary rod 606. During the movement of the slider 607, the adjusting rod 613 connected to its surface moves synchronously. The adjusting rod 613 then pushes the tension wheel 614 to change position. When the stainless steel wire passes over the tension wheel 614, the change in the position of the tension wheel 614 directly affects the tension of the wire: if the tension wheel 614 moves upward, the wire is stretched more, and the tension increases; conversely, the tension decreases, thus achieving the desired pulling tension. After the initial adjustment, once the slider 607 moves to the target position, the telescopic spring 609 inside the telescopic hole 608 pushes the limiting plate 610, causing the positioning block 611 to embed into the positioning hole 612 inside the slide groove 603, forming a mechanical lock. This structural design prevents the slider 607 from shifting due to the tension of the steel wire or equipment vibration during the pulling process, ensuring that the tension wheel 614 is fixed in position and maintaining a stable pulling tension. When the tension needs to be adjusted again, the servo motor 604 can be reversed to move the slider 607 and drive the positioning block 611 out of the positioning hole 612, allowing the tension adjustment operation to be performed again.

[0023] Furthermore, four identical sets of pulleys 4 are installed at the bottom of the base 1, symmetrically distributed at the four corners of the bottom of the base 1 along the central axis of the base 1. The pulleys 4 create a flexible and convenient moving system. The symmetrically distributed four sets of pulleys can evenly bear the overall weight of the device, ensuring that the base 1 remains horizontal and stable during movement and avoiding tilting due to uneven force. The pulleys are made of high-strength polyurethane material, which has both wear resistance and low noise characteristics. When moving on the workshop floor, the coefficient of friction is as low as 0.05, allowing operators to easily push the device to adjust its position and adapt to different production line layout requirements. In addition, the pulleys are equipped with a self-locking device. When the device is moved to the designated position, the pulley can be fixed by a foot-operated locking mechanism to prevent the device from shifting due to vibration during production. This balances mobility and operational stability, making it particularly suitable for stainless steel wire drawing production lines that require frequent adjustments to equipment position.

[0024] Furthermore, the transmission device 5 includes a first bracket 501, the bottom of which is fixedly connected to the top of the base 1. A unwinding drum 502 is installed on the inner side of the first bracket 501. A second bracket 503 is connected to the top of the base 1. A take-up drum 504 is installed on the inner end of the second bracket 503. One end of the take-up drum 504 is connected to a take-up shaft 505, and one end of the take-up shaft 505 is connected to a drive motor 506. Stainless steel wires 507 are attached to the surfaces of both the unwinding drum 502 and the take-up drum 504. A fixing frame 508 is also connected to the top of the base 1, and a [missing information - likely a component or component] is connected to the inner side of the fixing frame 508. Guide wheel 509 has a limit groove 510 on its surface. Tension sensor 511 is installed above guide wheel 509. Through the transmission device 5, when the stainless steel wire drawing operation starts, the transmission device 5 begins to operate. Unwinding drum 502 pre-winds the stainless steel wire 507 to be processed. As drive motor 506 is powered on, winding shaft 505 begins to rotate under the motor's drive, which in turn drives winding drum 504 to rotate. The winding drum 504, through the tension generated by the rotation, pulls the stainless steel wire 507 gradually unwinding it from unwinding drum 502, allowing the stainless steel wire 507 to be sequentially unwound. After passing the guide wheel 509 inside the fixed frame 508, the stainless steel wire 507 enters the subsequent drawing process. The limiting groove 510 on the surface of the guide wheel 509 can accurately hold the stainless steel wire 507, ensuring that it moves along a fixed trajectory and preventing the wire from deviating or slipping during transmission. At the same time, when the stainless steel wire 507 passes the tension sensor 511 above the guide wheel 509, the tension sensor 511 monitors the tension value of the wire in real time and feeds the data back to the control system. If the tension value deviates from the preset range, the control system will adjust the speed of the drive motor 506 based on the feedback information, directly changing the winding drum. The winding speed of 504 adjusts the tension of the steel wire. On the other hand, the linkage adjustment mechanism 6 adjusts the position of the tension wheel 614 through the servo motor 604 to further optimize the tension until the steel wire tension is restored to the set value. During the entire transmission process, the unwinding drum 502 continuously releases the stainless steel wire 507, and the winding drum 504 stably winds up the drawn steel wire. The guide wheel 509 and the limit groove 510 ensure the stability of the steel wire's movement path. The tension sensor 511, the drive motor 506, and the adjustment mechanism 6 form a closed-loop control to achieve dynamic balance and precise adjustment of the tension of the stainless steel wire during the drawing process.

[0025] Furthermore, the stainless steel wire 507 on the surface of the unwinding drum 502 is connected to the surface of the unwinding drum 502 via the limiting groove 510. The winding shaft 505 and the winding drum 504 cooperate to form a rotating structure through the interaction of the drive motor 506 and the winding shaft 505. Through the setting of the winding shaft 505, the drive motor 506 and the limiting groove 510, a stable and reliable wire transmission system is formed. The drive motor 506 can accurately control the speed and torque of the winding shaft 505, driving the winding drum 504 to wind at a uniform speed, ensuring that the stainless steel wire 507 maintains a constant traction force during the drawing process. The limiting groove 510 plays a guiding and limiting role for the wire, preventing the wire from deviating or falling out of the groove during transmission, controlling the error of the wire running trajectory within ±0.3mm, ensuring the continuity of the drawing operation. The three work together to meet the winding speed requirements of different specifications of wire and avoid wire breakage caused by tension fluctuations, thereby increasing production efficiency by more than 30%.

[0026] Furthermore, two identical sets of fixing rods 602 are provided above the base plate 601. One set of fixing rods 602 has a threaded rod 605 rotatably connected in the groove 603 on its surface, while the other set of fixing rods 602 has an auxiliary rod 606 fixedly connected in the groove 603 on its surface. Through the setting of the threaded rod 605 and the auxiliary rod 606, a stable two-dimensional guide drive structure is constructed. The threaded rod 605 provides rotational driving force, which cooperates with the threaded hole of the slider 607 to realize vertical lifting and lowering movement. The auxiliary rod 606 serves as a parallel guide rail, restricting the rotational freedom of the slider 607 and ensuring that it slides smoothly along a straight line. This design controls the motion error of the slider 607 to within ±0.1mm. Compared with the single threaded rod structure, the lateral load-bearing capacity is increased by 50%, which can effectively avoid the tilting of the adjusting rod 613 due to eccentric force, and improve the position adjustment accuracy of the tension wheel 614 to ±0.2mm, meeting the stringent requirements of tension control in high-precision drawing processes.

[0027] Furthermore, the slider 607 slides inside the groove 603 via the threaded rod 605 and the auxiliary rod 606. The outer wall size of the slider 607 matches the inner wall size of the groove 603. Through the arrangement of the groove 603 and the slider 607, a precise sliding constraint system is formed. The clearance fit between the two reaches H7 / g6 level. When the slider 607 slides in the groove 603, it ensures smooth motion performance and achieves high-precision positioning. The side wall of the groove 603 forms a three-dimensional constraint on the slider 607, which can withstand lateral forces of up to 500N, preventing jamming or shaking during adjustment. At the same time, the close-fitting structural design effectively prevents dust and reduces the wear of external impurities on the transmission components. This allows the device to maintain an adjustment accuracy of ±0.3mm after 1000 hours of continuous operation, significantly extending the service life of the equipment.

[0028] Furthermore, the dimensions of the positioning block 611 are adapted to the dimensions of the positioning hole 612, and multiple sets of positioning holes 612 are equally spaced on the inner side of the slide groove 603. Through the setting of the positioning block 611 and the positioning hole 612, a multi-level locking function for the tension adjustment position is realized. The positioning block 611 automatically embeds into the positioning hole 612 under the action of the telescopic spring 609, which can provide a locking force of up to 800N, ensuring that the slider 607 maintains a stable position during the pulling process and preventing displacement caused by vibration or wire tension. The equally spaced positioning holes support 16 levels of fine adjustment to meet the personalized requirements of different specifications of steel wire for the height of the tension wheel 614. When readjustment is required, simply drive the slider 607 to move, and the positioning block 611 automatically exits the positioning hole under the action of the inclined structure. The operation is convenient and the positioning is accurate, which shortens the tension adjustment response time to within 1.5 seconds, greatly improving production efficiency and process adaptability.

[0029] Working Principle: First, the operator can release the lock of pulley 4 using the foot-operated locking mechanism according to the specifications of the stainless steel wire and the drawing process requirements. Then, push the push rod 3 to move the device to a suitable position, and then lock pulley 4 again to ensure stable operation. After starting the equipment, the drive motor 506 of the transmission device 5 drives the winding shaft 505 and winding drum 504 to rotate, pulling the stainless steel wire 507 out from the unwinding drum 502. The wire passes through the limiting groove 510 of the guide wheel 509 and enters the drawing die. During this process, the guide wheel 509 ensures the stability of the wire's trajectory. The tension sensor 511 monitors the wire tension in real time and feeds the data back to the control system. If the tension sensor 511 detects that the tension deviates from the preset range, the control system will immediately activate a dual adjustment mechanism. On one hand, the control system directly adjusts the speed of the drive motor 506, changing the winding speed of the winding drum 504 to initially adjust the wire tension. On the other hand, the linkage adjustment mechanism 6, with the servo motor 604 driving the threaded rod 6... 05. Rotation: The slider 607, in cooperation with the threaded rod 605 and the auxiliary rod 606, slides up and down along the groove 603, driving the adjusting rod 613 and the tension wheel 614 to move, further precisely adjusting the tension of the steel wire. When the slider 607 moves to the target position, the positioning block 611, under the action of the telescopic spring 609, is embedded in the positioning hole 612, locking the position of the tension wheel 614 to prevent tension fluctuations during the drawing process. Throughout the drawing process, the adjusting mechanism 6, the transmission device 5, and the pulley 4 support system work together continuously. The pulley 4 ensures the stable placement of the device, the transmission device 5 maintains stable wire delivery and real-time tension monitoring, and the adjusting mechanism 6 dynamically adjusts the tension based on feedback. The three work closely together to ensure that the stainless steel wire maintains precise and stable tension throughout the drawing process, ensuring that the dimensional accuracy, surface quality, and mechanical properties of the drawn stainless steel wire meet the standards, while significantly reducing the risk of wire breakage and significantly improving production efficiency and product qualification rate. This completes the use of a stainless steel wire drawing tension adjusting device.
