Description

Technical Field

[0001] This application belongs to the field of steel cord production technology, and relates to a strong magnetic take-up shaft with spring plunger and a water tank wire drawing machine. Background Technology

[0002] Currently, one automation solution for existing water tank wire drawing machines involves using a robotic arm to load and unload the I-beams on the take-up shaft. To facilitate this loading and unloading, a certain gap (approximately 0.25mm) exists between the take-up shaft and the inner hole of the I-beam. Since the I-beam needs to be fixed during take-up to prevent displacement and ejection during high-speed rotation, the common solution is to use an air-expanding take-up shaft. The operation involves the robotic arm horizontally (or in a horizontal position) installing the I-beam onto the air-expanding take-up shaft. The robotic arm then inflates the air-expanding take-up shaft, causing the air bladder to expand and tighten the inner wall of the I-beam's central hole, ensuring the I-beam remains fixed. The take-up shaft then drives the I-beam to rotate and take in the wire. Once the I-beam is fully loaded, the robotic arm deflates the air bladder, causing it to retract, and the robotic arm unloads the fully loaded I-beam.

[0003] Using an air-expanded take-off spool presents the following problems: 1. The cost of use is relatively high, with a unit price of approximately 1000 yuan per unit; 2. The need for a robotic arm to inflate and deflate the airbags during loading and unloading increases working time, reduces production efficiency, and the frequent inflation and deflation leads to a high failure rate of the airbags, which also affects production efficiency and increases repair costs. 3. Because the air expansion take-up shaft has a hollow design and a wall thickness of 5mm, and the wall thickness of the airbag mounting part is less than 5mm, deformation will occur when using heavy I-beam reels, which will seriously affect the service life of spare parts, thereby further increasing the failure rate and repair costs. 4. To ensure that the I-beam reel is securely fastened and does not move after being installed on the air-expanding take-up shaft, the compressed air pressure of the airbag needs to be around 0.6 MPa. Since other equipment in the workshop generally requires around 0.4 MPa, the robot needs to be equipped with a booster pump, which increases the equipment commissioning cost and compressed air consumption cost. Utility Model Content

[0004] Objective: In view of at least one of the above technical problems, this application provides a strong magnetic take-up spool with a spring plunger, which replaces the air-expanded take-up spool, thereby reducing equipment failure rate and operating costs.

[0005] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: In a first aspect, a strong magnetic take-up spool with a spring plunger is provided, comprising a take-up spool, a strong magnet, a spring pin, and a spring plunger; the take-up spool includes a take-up spool flange and a take-up spool shaft connected to each other; the side of the take-up spool flange facing the take-up spool shaft is provided with a plurality of strong magnet mounting grooves and at least one spring pin mounting hole; A strong magnet is installed in a strong magnet mounting groove to attract the I-beam wheel by strong magnetism; The spring pin is installed in the spring pin mounting hole. In the pop-out state, the spring pin engages with the positioning pin hole on the corresponding end face of the I-beam wheel, driving the I-beam wheel to rotate. The take-up spool has a radially opened plunger hole for installing a spring plunger. The spring plunger is installed in the plunger hole. The ball of the spring plunger is pressed tightly against the inner wall of the I-beam wheel under the action of the spring, which plays an auxiliary stabilizing role for the I-beam wheel.

[0006] In some embodiments, the spring pin includes a compression spring and a pin connected together, and has two working states: pop-out and retracted. In the pop-out state, the end of the pin pops out to a height above the surface of the take-up flange under the action of the compression spring, and engages with the positioning pin hole on the corresponding end face of the I-beam. In the retracted state, the pin compresses the compression spring and retracts into the spring pin mounting hole, and the end of the pin does not exceed the surface of the take-up flange.

[0007] Furthermore, the pin includes a pin shaft portion and a compression spring mounting portion that are connected to each other; The spring pin also includes a retaining clip connected to the opening of the spring pin mounting hole. The retaining clip has a through hole for the pin shaft to pass through. The diameter of the through hole of the retaining clip is larger than the outer diameter of the pin shaft and smaller than the outer diameter of the compression spring mounting part. One end of the compression spring is connected to the bottom of the spring pin mounting hole, and the other end is installed in the groove of the compression spring mounting part. The limiting snap ring is sleeved on the outer circumference of the pin shaft to prevent the pin from falling off.

[0008] In some embodiments, the spring plunger includes a spring and a ball connected together. When the H-beam is installed into the take-up spool, after the inner wall of the H-beam contacts the spring plunger, the ball of the spring plunger retracts. After the H-beam is assembled, the ball presses tightly against the inner wall of the H-beam under the action of the spring, which plays an auxiliary stabilizing role for the H-beam.

[0009] Furthermore, the spring plunger also includes a housing, with the spring and ball disposed inside the housing, and the ball being positioned at the opening of the housing; when the spring inside the spring plunger is compressed, it generates a preload force, which pushes the ball to extend outward and contact the inner wall of the I-beam wheel to form a locking effect; when the external force exceeds the spring preload force, the ball compresses the spring and retracts into the housing, achieving buffering or avoidance.

[0010] In some embodiments, multiple strong magnets are evenly arranged around the circumference of the take-up shaft flange.

[0011] In some embodiments, the strong magnet has a cylindrical structure.

[0012] In some embodiments, the strong magnet is fixedly installed in the strong magnet mounting groove by a countersunk screw, and the outer surface of the strong magnet is flush with the surface of the take-up shaft flange.

[0013] In some embodiments, the take-up flange is provided with two spring pins, and the line connecting the centers of the two spring pins overlaps with the diameter of the take-up flange.

[0014] In some embodiments, six spring plungers are evenly installed circumferentially on the take-up spool.

[0015] Secondly, a water tank wire drawing machine is provided, including the aforementioned strong magnetic take-up shaft with spring plunger.

[0016] Beneficial Effects: The strong magnetic take-up spool with spring plunger provided in this application allows the robotic arm to horizontally mount the I-beam reel onto the take-up spool. The strong magnet on the take-up spool flange attracts and secures the I-beam reel. When the take-up spool accelerates or decelerates, causing asynchronous movement between the I-beam reel and the take-up spool, the spring pin automatically pops out and engages with the positioning pin hole of the I-beam reel, ensuring the take-up machine can drive the I-beam reel to rotate. During high-speed rotation of the I-beam reel, the ball bearing of the spring plunger on the take-up spool shaft is pressed tightly against the inner wall of the I-beam reel under the action of the spring, providing a certain degree of stability and reducing vibration and abnormal noise caused by gaps between the I-beam reel and the take-up spool shaft. After the I-beam reel is fully wound, the robotic arm can directly pull it out without any other actions. It has the following advantages: the robotic arm only performs the actions of loading and unloading the I-beam reel, resulting in short processing time and high work efficiency; the configured strong magnet, spring pin, and spring plunger have a low failure rate, and the use of compressed air and other costs effectively reduces various input costs.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0020] Example 1: As Figure 1 As shown, a strong magnetic take-up shaft with a spring plunger includes a take-up shaft 1, a strong magnet 3, a spring pin 4, and a spring plunger 5; the take-up shaft 1 includes a take-up shaft flange 101 and a take-up shaft portion 102 connected to each other; the take-up shaft flange 101 is provided with a plurality of strong magnet mounting grooves and at least one spring pin mounting hole on the side facing the take-up shaft portion 102; A strong magnet 3 is installed in a strong magnet mounting groove to attract the I-shaped wheel 6 by means of the strong magnet 3; The spring pin 4 is installed in the spring pin mounting hole. In the pop-out state, the spring pin 4 cooperates with the positioning pin hole 601 on the corresponding end face of the I-beam wheel 6, driving the I-beam wheel 6 to rotate. The take-up shaft 102 has a radially opened plunger hole for installing the spring plunger 5. The spring plunger 5 is installed in the plunger hole. The ball of the spring plunger 5 presses tightly against the inner wall of the I-beam wheel 6 under the action of the spring, which plays an auxiliary stabilizing role for the I-beam wheel.

[0021] In this embodiment, multiple strong magnets 3 are evenly arranged around the circumference of the take-up shaft flange 101; in this embodiment, eight strong magnets 3 are evenly arranged around the circumference of the take-up shaft flange 101. Further, the strong magnets 3 have a cylindrical structure with a diameter of 25 mm and a thickness of 10 mm.

[0022] In this embodiment, the strong magnet 3 is fixedly installed in the strong magnet mounting groove by a countersunk screw 2, and the outer surface of the strong magnet 3 is flush with the surface of the take-up shaft flange 101. The use of a countersunk screw ensures that the H-beam reel can fit tightly against the surface of the take-up shaft flange.

[0023] In some embodiments, such as Figure 1 As shown, the spring pin 4 includes a compression spring 402 and a pin 401 connected to each other, and has two working states: pop-out and retracted. In the pop-out state, the end of the pin 401 pops out under the action of the compression spring 402 to a height higher than the surface of the take-up flange 101, and engages with the positioning pin hole 601 on the corresponding end face of the I-beam 6. In the retracted state, the pin 401 compresses the compression spring 402 and retracts into the spring pin mounting hole, and the end of the pin does not exceed the surface of the take-up flange 101.

[0024] Furthermore, such as Figure 1 , Figure 2 As shown, the pin 401 includes a pin shaft portion 4011 and a compression spring mounting portion 4012 connected to each other; The spring pin 4 also includes a limiting snap ring 403 connected to the opening of the spring pin mounting hole. The limiting snap ring 403 is provided with a through hole for the pin shaft portion 4011 to pass through. The diameter of the through hole of the limiting snap ring 403 is larger than the outer diameter of the pin shaft portion 4011 and smaller than the outer diameter of the compression spring mounting portion 4012 (used to limit the compression spring mounting portion 4012). One end of the compression spring 402 is connected to the bottom of the spring pin mounting hole, and the other end is installed in the groove of the compression spring mounting part 4012. The limiting snap ring 403 is sleeved on the outer periphery of the pin shaft part 4011 to prevent the pin 401 from falling off.

[0025] In this embodiment, as Figure 1 , Figure 2 As shown, the compression spring mounting part 4012 is a hollow cylindrical structure with an opening at one end and a groove for mounting the compression spring 402; the pin shaft part 4011 is installed at the center position of the other end of the compression spring mounting part 4012, and the outer diameter of the pin shaft part 4011 is smaller than the outer diameter of the compression spring mounting part 4012.

[0026] In this embodiment, two spring pins 4 are provided on the take-up spindle flange 101, and the line connecting the centers of the two spring pins 4 overlaps with the diameter of the take-up spindle flange 101. This is to prevent the I-beam and the take-up spindle from moving asynchronously during the start-up and stop of the machine tool, which may be caused by the acceleration or deceleration of the take-up spindle.

[0027] In some embodiments, the spring plunger 5 includes a spring and a ball connected together. When the I-beam 6 is installed into the take-up shaft 1, after the inner wall of the I-beam 6 contacts the spring plunger 5, the ball of the spring plunger 5 retracts. After the I-beam 6 is assembled, the ball presses tightly against the inner wall of the I-beam 6 under the action of the spring, which plays an auxiliary stabilizing role for the I-beam 6.

[0028] Furthermore, the spring plunger 5 also includes a housing, with the spring and ball disposed inside the housing, and the ball being positioned at the opening of the housing; when the spring inside the spring plunger is compressed, it generates a preload force, which pushes the ball to extend outward and contact the inner wall of the H-beam wheel to form a locking effect; when the external force exceeds the spring preload force, the ball compresses the spring and retracts into the housing, achieving buffering or avoidance.

[0029] In this embodiment, the spring compression is adjusted by the depth of thread insertion, thereby controlling the spring preload to adapt to different load requirements. The key structural components of the spring plunger 5 include: Housing: Typically made of metal (such as stainless steel) or plastic, with threads for easy installation and securing. Springs: Provide elastic force and must possess high strength and fatigue resistance. Moving parts: Ball bearings (for smooth contact surfaces), made of wear-resistant and corrosion-resistant material. In this embodiment, steel balls are used. Spring plungers are a relatively mature product in the prior art, and will not be described in detail here.

[0030] In this embodiment, six spring plungers 5 are evenly installed circumferentially on the take-up shaft 102. The spring plungers are internally compressed with springs and have ball bearings at the front end, which can help stabilize the H-shaped wheel during rotation and reduce vibration and noise of the take-up machine during operation.

[0031] In this embodiment, the ball protrudes 1mm beyond the take-up shaft 102, and the I-beam 9 is clamped by the robot arm 8 and horizontally inserted. There is generally a 0.25mm gap between the inner hole of the I-beam 9 and the take-up shaft 102. When the robot arm horizontally inserts the take-up shaft and contacts the spring plunger 5, the ball inside retracts, pressing tightly against the inner hole of the I-beam 9 under the action of the spring, thus providing auxiliary stability. After the I-beam 9 contacts the take-up shaft flange 101, the spring pin 4 retracts and is firmly attracted by the strong magnet 3. When the take-up shaft rotates, it drives the I-beam 9 to rotate, achieving the purpose of rotating the I-beam 9 to take up the yarn. During acceleration and deceleration of the take-up spool, the strong magnet may not fully engage the I-beam 6, causing asynchronous movement between the I-beam 6 and the take-up spool. When the I-beam 6 moves to the position where the positioning pin hole 601 aligns with the spring pin 4, the spring pin 4 on the take-up spool will automatically pop out and engage with the positioning pin hole 601 of the I-beam 6, ensuring that the take-up spool can drive the I-beam 6 to rotate. After the I-beam 6 is fully wound up, the robotic arm 7 directly pulls the I-beam 6 horizontally without any other actions.

[0032] The working method of the strong magnetic take-up shaft with spring plungers provided in this embodiment is as follows: Using a strong magnetic take-up shaft with spring plungers, the robot arm 7 horizontally installs the I-beam 6 onto the take-up shaft. The strong magnet 3 on the take-up shaft flange 101 attracts the I-beam 6, fixing it in place. When the take-up shaft accelerates or decelerates, and the I-beam 6 and the take-up shaft may move out of sync, the spring pin 4 automatically pops out and engages with the positioning pin hole of the I-beam 6, ensuring that the take-up machine can drive the I-beam 6 to rotate. When the I-beam 6 rotates at high speed, the balls of the six spring plungers on the take-up shaft shaft 102 press tightly against the inner wall of the I-beam 6 under the action of the springs, providing a certain degree of stability to the I-beam 6 and reducing vibration and abnormal noise caused by the gap between the I-beam 6 and the take-up shaft shaft 102. After the I-beam 6 is fully wound, the robot arm 7 can directly pull out the I-beam 6 without any other actions. It has the following advantages: 1. Low operating cost, approximately 500 yuan per unit; 2. The loading and unloading of wheels is simplified, resulting in high production efficiency; 3. The strong magnetic take-up spool has a simple structure, low failure rate, and reduces repair costs; 4. The take-up spool is solid, which meets the requirements of heavy-duty I-beam reels and has a wide range of applications; 5. The strong magnetic take-up spool does not use compressed air, which reduces the equipment commissioning cost and compressed air consumption cost.

[0033] This application provides a strong magnetic take-up spool with a spring plunger, which has a simple structure and is easy to operate. It can eliminate the problems of air-expanded take-up spools and meet the needs of automated production by robotic arms.
