Description

Technical Field

[0001] This invention relates to the technical field of rust removal devices for metal wires, and particularly to a rust removal device and process for the surface of metal wires. Background Technology

[0002] In the processing and preparation of metal wire products, surface pretreatment such as rust removal, oil removal, polishing, and roughening is usually required. Currently, sandpaper or diamond cloth are commonly used to remove rust from the surface of metal wire.

[0003] Chinese patent CN220806798U discloses a rust removal device for a metal wire surface treatment system. The device uses two rust removal wheel assemblies that rotate synchronously with a rotating frame to form a revolution relative to the metal wire. At the same time, the two rust removal wheel assemblies rotate around their own axes to form a rotation relative to the metal wire, which can greatly improve the rust removal efficiency and accuracy of the metal wire.

[0004] The aforementioned device polishes the metal wire using rust-removing wheels and adjusts the distance between the rust-removing wheels using a spacing adjustment mechanism. However, during use, the spacing adjustment mechanism cannot precisely adjust the pressure between the rust-removing wheels and the metal wire. Furthermore, the device needs to be stopped during adjustment. If a drive component is introduced to connect to the rust-removing wheels to dynamically adjust the distance between them, the overall structure of the device would become too complex and maintenance costs would increase because the rust-removing wheels are in a state of revolution and rotation.

[0005] Therefore, it is necessary to provide a rust removal device and process for metal wire surfaces to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rust removal device and process for metal wire surfaces, in order to solve the problem mentioned in the background art that the existing device grinds the metal wire with a rust removal wheel and adjusts the distance between each rust removal wheel by a spacing adjustment mechanism. However, during use, the spacing adjustment mechanism cannot precisely adjust the pressure between the rust removal wheel and the metal wire.

[0007] Based on the above ideas, the present invention provides the following technical solution: a rust removal device for metal wire surfaces, comprising multiple sets of central tubes, an area between adjacent sets of central tubes for exposing the metal wire to be polished, and further comprising: A turntable is coaxially arranged with the central tube and sleeved on the outside of the central tube; The grinding component, located on one side of the turntable, is used to grind rust off the outer side of the metal wire; A longitudinal adjustment member, the grinding assembly bypassing the outside of the longitudinal adjustment member; A disc rotates synchronously with the turntable. A traction member is provided on one side of the turntable, and the traction member can slide relative to the disc along its diameter. A pressing member is hinged between the longitudinal adjusting member and the traction member, and the pressing member can rotate around a pin on the disc.

[0008] As a further aspect of the present invention: the grinding component is a flexible sanding belt, the turntable is provided with a rotating shaft and a lateral adjustment component, the rotating shaft and the turntable are rotatably engaged, the lateral adjustment component is elastically connected to the turntable in a direction perpendicular to the diameter of the turntable, and the sanding belt is sleeved on the outside of the rotating shaft, the longitudinal adjustment component and the lateral adjustment component.

[0009] As a further aspect of the present invention: a gear is fixedly sleeved on the outer side of the rotating shaft, and a gear ring that meshes with the gear is provided on one side of the turntable.

[0010] As a further aspect of the present invention: the top pressing member is a plate-shaped structure, and a through strip groove is provided on the top pressing member, and a protrusion is provided on the traction member that slides with the strip groove.

[0011] As a further aspect of the present invention: a limiting member is sleeved on the outer side of the disk, and a boss fixed on the traction member can slide and engage with the disk along the diameter direction of the disk. A shaft-shaped abutment is attached to the outer circumferential surface of the limiting member, and the abutment and the boss are elastically connected.

[0012] As a further aspect of the present invention, the diameter of the section from the highest point to the lowest point on the outer circumference of the limiting member gradually decreases.

[0014] As a further aspect of the present invention, the connecting member and the longitudinal adjusting member are in sliding engagement.

[0015] As a further aspect of the present invention: the connecting member is hinged to the base on the longitudinal adjusting member.

[0016] A rust removal process for metal wire surfaces includes the following steps: rust removal, using the aforementioned metal wire surface rust removal equipment to remove rust from the surface of the metal wire; annealing, subjecting the roughly drawn metal wire to spheroidizing annealing; post-treatment, applying a physical or chemical reaction film to the metal wire online and performing saponification lubrication treatment; and fine drawing, performing fine drawing on the metal wire to complete the rust removal.

[0017] Compared with existing technologies, the advantages of this invention are: by controlling the rotation speed of the turntable, the pressure between the sanding belt and the metal wire can be adjusted, and the adjustment steps can be completed smoothly during equipment operation, making operation convenient.

[0021] like Figures 1-9As shown, a rust removal device for metal wire surfaces includes a wire feeding device 1 for metal wire 3 and a rust removal device 2 for removing rust from the metal wire 3. It should be noted that the wire feeding device 1 can be a reel wound with the metal wire 3, driven by a motor to rotate, or a device such as... Figure 1 The wire feeding device 1 shown winds the metal wire 3 onto a roller. The metal wire 3 pulled from the roller passes sequentially through pressure rollers arranged in the vertical direction and pressure rollers arranged in the horizontal direction, so that the metal wire 3 enters the rust removal device 2 in a straightened state. Specifically, the wire feeding device 1 can be selected from the prior art, and the improvement of the present invention is mainly in the rust removal device 2. Therefore, the specific structure of the wire feeding device 1 will not be described in detail.

[0022] The rust removal device 2 includes a frame and multiple sets of central tubes 4 disposed within the frame. Space is left between adjacent sets of central tubes 4 to expose the area of ​​the metal wire 3 to be polished. A turntable 14 is sleeved on the outside of the central tube 4. A polishing component is disposed on one side of the turntable 14. A gear 701 is disposed at the input end of the polishing component, and a gear ring 5 is meshed on the outside of the gear 701. During the rotation of the turntable 14, the gear 701 can mesh with the gear ring 5. Through this structure, the polishing component can also rotate on its own axis while the turntable 14 revolves around the central axis, thereby improving the polishing efficiency of the metal wire 3.

[0023] As one embodiment of the grinding assembly, the grinding assembly can be a grinding wheel. The contact between the grinding wheel and the outer surface of the metal wire 3 can grind away rust on the outer side of the metal wire 3. In this embodiment, while ensuring the gear 701 meshes with the gear ring 5, the position of the grinding assembly relative to the metal wire 3 is not easily adjustable. Based on this, this solution provides another embodiment of the grinding assembly, combined with... Figure 2 As shown, the grinding assembly can be a flexible sanding belt 6. Correspondingly, the turntable 14 is provided with a rotating shaft 7, a longitudinal adjusting member 20, and a transverse adjusting member 25. The rotating shaft 7 and the turntable 14 are rotatably coupled through bearings. The longitudinal adjusting member 20 can move relative to the turntable 14 along its diameter direction, while the transverse adjusting member 25 can move in a direction perpendicular to the diameter of the turntable 14. The transverse adjusting member 25 is elastically connected to the turntable 14. In this embodiment, the gear 701 is fixedly sleeved on the outside of the rotating shaft 7, so that the position of the longitudinal adjusting member 20 can be adjusted when the gear 701 meshes with the gear ring 5, thereby adjusting the position of the grinding assembly relative to the metal wire 3.

[0024] Furthermore, in the embodiment for adjusting the position of the sanding belt 6 relative to the metal wire 3, the longitudinal adjustment member 20 can be mounted on the turntable 14 via an elastic component such as a spring. Under the action of elasticity, the longitudinal adjustment member 20 is brought closer to the metal wire 3 to press the sanding belt 6 tightly against the outer surface of the metal wire 3. This can accommodate metal wires 3 of different thicknesses, which is beneficial to improving the overall applicability of the device. However, during use, if it is necessary to adjust the pressure between the sanding belt 6 and the metal wire 3, the operation of the equipment needs to be stopped to replace or adjust the elastic component, which is not conducive to the continuous grinding operation. Based on this, the present invention provides another embodiment for adjusting the position of the sanding belt 6, combined with... Figures 3-8 As shown, a disc 9 is provided on the side of the turntable 14 away from the sanding belt 6. The disc 9 is sleeved on the outside of the central tube 4 and is coaxially arranged with the central tube 4. The disc 9 and the turntable 14 rotate synchronously. A top-pressing member 17 is provided on the disc 9. The top-pressing member 17 can rotate around the pin 16 on the disc 9. A traction member 8 is provided on one side of the disc 9. The traction member 8 can slide relative to the disc 9 along its diameter. It should be noted that the top-pressing member 17 is located between the longitudinal adjustment member 20 and the traction member 8. When the rotation speed of the turntable 14 changes, the centrifugal force on the traction member 8 will change accordingly. In turn, the pressure on the longitudinal adjustment member 20 is changed by the top-pressing member 17, which is beneficial to adjust the pressure between the sanding belt 6 and the metal wire 3. In this embodiment, the pressure between the sanding belt 6 and the metal wire 3 can be adjusted without stopping the operation of the equipment. In addition, adjusting the pressure between the sanding belt 6 and the metal wire 3 by changing the rotation speed of the turntable 14 itself can simplify the structure to the greatest extent and improve the stability of the equipment operation.

[0025] The top pressing member 17 has a plate-like structure and a through strip groove 1701. The traction member 8 has a protrusion 802 that slides with the strip groove 1701. The end of the top pressing member 17 away from the strip groove 1701 is connected to the longitudinal adjusting member 20 through a connector 22. As the protrusion 802 moves synchronously with the traction member 8, the force between the protrusion 802 and the strip groove 1701 can cause the top pressing member 17 to rotate around the pin 16, thereby adjusting the pressure between the top pressing member 17 and the longitudinal adjusting member 20.

[0026] In summary, when this device is in use, the metal wire 3 is passed through the central tube 4, and the turntable 14 drives the disc 9 to rotate synchronously. During this process, the traction member 8 is affected by centrifugal force and slides outward relative to the disc 9 along its diameter. During this process, the cooperation between the protrusion 802 and the strip groove 1701 can cause the top pressure member 17 to rotate around the pin 16 and increase the pressure on the longitudinal adjustment member 20, so that the sanding belt 6 sleeved on the outside of the longitudinal adjustment member 20 is in contact with the surface of the metal wire 3. Through the meshing of the gear 701 and the gear ring 5, the sanding belt 6 can rotate on its own during the rotation of the turntable 14, so that the sanding belt 6 can fully polish the rust on the outer surface of the metal wire 3. Before grinding the metal wire 3, the thickness of the rust can be detected using an electromagnetic ultrasonic sensor. For example, the electromagnetic ultrasonic sensor can be mounted on the periphery of the metal wire 3 via a bracket, so that the part of the metal wire 3 to be ground passes through the electromagnetic ultrasonic sensor before contacting the sanding belt 6. Of course, the electromagnetic ultrasonic sensor is used to control the rotation speed of the turntable 14. When the rust on the metal wire 3 is thick, the rotation speed of the turntable 14 can be increased to increase the pressure of the top pressure member 17 on the longitudinal adjustment member 20. When the pressure between the sanding belt 6 and the surface of the metal wire 3 increases, the rust removal effect can be further improved; conversely, the rotation speed of the turntable 14 can be decreased. In this embodiment, controlling the rotation speed of the turntable 14 can adjust the pressure between the sanding belt 6 and the metal wire 3, and the adjustment steps can be completed smoothly during equipment operation, making operation convenient. It should be noted that the dynamic adjustment of the turntable 14 by the electromagnetic ultrasonic sensor can achieve dynamic grinding of the rust on the outer surface of the metal wire 3, which helps to avoid the problem of over-grinding the metal wire 3 and damaging it, or under-grinding and leaving rust residue.

[0027] The pressure between the abrasive belt 6 and the metal wire 3 can be adjusted by the traction component 8. However, to improve the stability of the pressure between the abrasive belt 6 and the metal wire 3, a ring-shaped closed limiting component 10 is sleeved on the outside of the disc 9. Figures 3-8 As shown, a boss 803 is fixedly provided on one side of the traction member 8, and a through groove is provided on the disk 9 for the boss 803 to slide. Specifically, the boss 803 can move along the diameter direction of the disk 9. A shaft-shaped abutment 13 is attached to the outer circumferential surface of the limiting member 10. The abutment 13 is rotatably mounted on the connecting block. (Refer to...) Figure 5 As shown, the connecting block and the boss 803 are fixedly connected by a telescopic rod 18, and a limit spring is fixedly installed between the connecting block and the boss 803. Figures 4-5As shown, during the rotation of the disk 9, the abutment 13 can rotate along the outer circumference of the limiting member 10. It should be noted that the highest point on the outer circumference of the limiting member 10 is denoted as point a, and the lowest point is denoted as point c. The point between points a and c is marked as point b. The diameter of the portion of the outer circumference of the limiting member 10 located between points a and c gradually decreases. Specifically, when the disk 9 drives the traction member 8 to rotate to the highest point, the abutment 13 is located at point a. At this time, the limiting member 13... The limiting spring is stretched to its maximum position, and the tension of the limiting spring on the traction member 8 is equal to the weight of the traction member 8 itself. When the disc 9 drives the traction member 8 to rotate to the lowest point, the abutment member 13 is located at point c. At this time, the limiting spring is compressed to its maximum position, and the pressure of the limiting spring on the traction member 8 is equal to the weight of the traction member 8 itself. Furthermore, when the disc 9 drives the traction member 8 to rotate to point b, the abutment member 13 is located at point b. At this time, the limiting spring is in a state of natural stress. In summary, in this structure, the cooperation between the limiting spring and the limiting member 10 offsets the weight of the traction member 8 itself, so that the top pressing member 17 only transmits the centrifugal force on the traction member 8, thereby improving the stability of the surface pressure between the sanding belt 6 and the metal wire 3, which is beneficial to improving the grinding effect.

[0028] It should be noted that the component of the gravity of the traction component 8 along the diameter of the disk 9 satisfies a trigonometric function, while the elastic force of the limiting spring satisfies a linear function. Therefore, the part of the outer circumference of the limiting component 10 between points a and c can be a polyline or an arc to improve the accuracy of the fitting of the linear function and the trigonometric function.

[0029] Reference Figure 1 As shown, a pipe fitting 12 is provided at the center of the turntable 14 and the disc 9, and the pipe fitting 12 passes through the turntable 14 and the disc 9 and is fixedly connected to both. Specifically, the pipe fitting 12 is sleeved on the outside of the central pipe 4. A base 11 is installed on the frame, and the pipe fitting 12 passes through the base 11 and rotates with it through a bearing. Figures 2-3 As shown, a motor is installed on the base 11, and the output shaft of the motor is connected to the tube 12 through a transmission assembly 15. The transmission assembly 15 can be a belt or chain, etc. The electromagnetic ultrasonic sensor can be electrically connected to the motor through a controller to control the rotation speed of the turntable 14. The limiting member 10 is fixedly connected to the base 11, and the gear ring 5 can be selectively fixedly connected to the base 11 or the frame.

[0030] The central tube 4 is fixedly connected to the frame via a rod.

[0031] Combination Figure 3As shown, multiple sets of counterweights 801 can be threadedly connected to the traction member 8. The counterweights 801 can be threadedly connected to the traction member 8. Two sets of L-shaped positioning elements 901 are fixedly installed on the side of the disc 9 near the traction member 8, while the portion of the traction member 8 located between the two sets of positioning elements 901 has a T-shaped structure, ensuring a stable fit between the traction member 8 and the disc 9. Figure 5 As shown, the disc 9 has a slot for the top pressing member 17 to pass through. The pin 16 is fixed in the slot and passes through the top pressing member 17 and is rotatably connected to it. A sleeve 19 is rotatably sleeved on the outside of the longitudinal adjusting member 20, and the sanding belt 6 is sleeved on the outside of the sleeve 19. Figure 5 As can be seen, the turntable 14 is provided with a longitudinal groove through which the longitudinal adjustment member 20 passes, and the square block 2001 rotatably sleeved on the outside of the longitudinal adjustment member 20 slides in the longitudinal groove. Of course, a stop 21 can be fixed on one side of the square block 2001. By the stop 21 being in contact with the end face of the turntable 14, the movement of the longitudinal adjustment member 20 relative to the turntable 14 along its axial direction can be prevented.

[0032] Combination Figure 6 The turntable 14 is provided with a transverse groove for the transverse adjustment member 25 to pass through. Similarly, the square block 2001 fixed on the transverse adjustment member 25 also slides in the transverse groove. Figure 6 As can be seen, a ring-shaped part is rotatably sleeved on the transverse adjustment member 25, and a connecting rod 23 is fixedly installed on the outer circumference of the ring-shaped part. The connecting rod 23 passes through the protrusion fixed on the turntable 14 and slides with the protrusion. An elastic element 24 is provided between the end of the connecting rod 23 and the protrusion. The elastic element 24 can be a spring. When the longitudinal adjustment member 20 drives the sanding belt 6 to adhere to the surface of the metal wire 3, the transverse adjustment member 25 can move relative to the turntable 14 and can compress the elastic element 24 in the process.

[0033] Combination Figure 5 , Figure 7 As shown, the connector 22 can be slidably sleeved on the outside of the longitudinal adjusting member 20, while the bottom end of the pressing member 17 is hinged to the connector 22. Alternatively, the connector 22 is a rod-shaped structure, with one end of the connector 22 hinged to the pressing member 17 and the other end of the connector 22 hinged to the base on the longitudinal adjusting member 20, so that the pressing member 17 can apply pressure to the longitudinal adjusting member 20 during the deflection process.

[0034] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
