Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and more specifically to a grinding device for the exterior of wire. Background Technology

[0002] As is well known, wire rod is the smallest type of hot-rolled steel in terms of cross-sectional dimensions. It generally refers to hot-rolled round steel or shaped steel with a diameter of 5-60mm. Since it is delivered in coiled form, it is collectively referred to as wire rod or wire bar. Because the atmosphere contains oxygen, wire rod is inevitably affected by the environment and corroded during transportation and storage. Therefore, when using wire rod, especially in environments with high requirements for wire rod quality, it is usually necessary to perform rust removal operations on the surface of the wire rod. Therefore, we propose a grinding device for the external surface of wire rod to assist in the treatment of wire rod with surface rust.

[0003] A search revealed that Chinese patent application number CN201620291102.8 discloses a belt grinding machine for removing rust from wire. The general description includes a transmission mechanism mounted on a frame to drive two rotating discs to rotate synchronously. Two grinding units with identical functions and structures are respectively arranged on the front and rear rotating discs. Each grinding unit includes a belt frame consisting of a drive wheel mechanism, a support wheel axle mechanism, and a tension wheel mechanism arranged in a triangular pattern to drive the belt ring to rotate and grind the wire for rust removal. The belt frame is located outside the belt ring. The semi-cylindrical support plate device between the side, drive wheel mechanism and tension wheel mechanism is used to support the sanding belt ring and the wire in a tight fit. The sanding belt frame and sanding belt ring revolve around the wire under the rotation of the rotating disk. The wire enters through the wire guide mold set at the front end of the semi-cylindrical support plate device located at the front end of the transmission mechanism and the wire guide hole in the center of the rotating disk, and exits through the wire insertion hole set at the rear end of the transmission mechanism and the wire insertion hole set at the top of the semi-cylindrical support plate device. In use, the rust layer on the surface of the wire is treated by the sanding belt ring grinding relative to the wire.

[0004] While the aforementioned existing technical solutions can perform grinding operations relative to the outside of the wire to remove rust, they are limited by the contact range between a single abrasive belt ring and the wire surface in a single operation. This requires the use of multiple abrasive belt rings to perform grinding operations relative to the wire in sequence to complete the full-circle grinding operation of the entire outside of the wire. This places high demands on the coordination of the multiple abrasive belt rings. If the coordination of the multiple abrasive belt rings is not good, it is easy to cause local omissions or repeated treatments on the outside of the wire, which will affect the external shape of the wire. The grinding quality is difficult to guarantee, and the practicality needs to be further improved. Summary of the Invention

[0040] Example

[0041] Please see the appendix Figure 1 - Appendix Figure 16A grinding device for the exterior of wire includes a transmission mechanism and a main structure. The main structure includes a base frame 1, a processing box 2 fixedly connected inside the base frame 1, a wire-passing port 3 on the processing box 2 for the wire to pass through, a fixed box 4 fixedly connected to the top of the processing box 2, lifting boxes 5 slidably connected to both the front and rear ends of the processing box 2, and guide frames 39 fixedly connected to both the front and rear ends of the processing box 2. The two lifting boxes 5 are slidably connected inside the two guide frames 39 respectively. Multiple fixed coils 6 and multiple fixed conductors 7 are arranged inside the fixed box 4. The multiple fixed coils 6 are wound around the multiple fixed conductors 7. Through the cooperation of the processing box 2, the fixed box 4, the fixed coils 6, and the fixed conductors 7, the fixed coils 6 and fixed conductors 7 can be ground. The abrasive particles attracted by the generated electromagnetic field are gathered, and the wire to be processed can be passed through the gathered abrasive particles to achieve external grinding treatment of the wire. This allows for complete single-cycle, full-loop processing of the wire, with relatively stable processing quality. Each of the two lifting boxes 5 is equipped with multiple lifting coils 8 and multiple lifting conductors 9. The lifting coils 8 are wound around the lifting conductors 9. The transmission structure is installed within the base frame 1. The transmission mechanism includes an electric adjusting rod and a synchronous frame 33. Both lifting boxes 5 are fixedly connected to the synchronous frame 33, and the electric adjusting rod is hinged to the synchronous frame 33. The electric adjusting rod is hinged within the base frame 1, and the transmission structure is used for the lifting adjustment and height control of both lifting boxes 5 relative to the processing box 2. This is achieved through the transmission mechanism, lifting boxes 5, lifting coils 8, and lifting conductors. With the cooperation of 9, the abrasive that has fallen into the processing box 2 can be lifted again and enter the electromagnetic field area formed by the fixed coil 6 and the fixed conductor 7 to achieve continuous grinding of the wire. The abrasive can be recycled, and the frequency of manual maintenance is low. An inclined arc-shaped support plate is fixedly connected inside the processing box 2. There are gaps between the left end of the inclined arc-shaped support plate and the inner left wall of the processing box 2, and between the left end of the inclined arc-shaped support plate and the inner right wall of the processing box 2. The bottom end of the processing box 2 is provided with a bottom slope with an upper opening. A filter plate 10 is detachably installed in the upper opening. A guide collection box 11 matching the bottom slope is installed on the processing box 2. An insertion frame 40 is fixedly connected to the bottom end of the processing box 2. An insertion plate 4 is slidably fitted inside the insertion frame 40. 1. An insertion plate 41 is fixedly connected to a guide collection box 11. Multiple handheld brackets 42 are fixedly connected to the guide collection box 11. A limiting plate 43 is rotatably connected to the processing box 2. The limiting plate 43 matches the guide collection box 11. Through the setting of the bottom slope of the processing box 2 and the cooperation of the filter plate 10 and the guide collection box 11, the abrasive can be cleaned and the dust falling from the wire can be collected. The processing box 2 has two inclined insertion holes 34. Each of the two inclined insertion holes 34 is equipped with a cleaning brush 35. A first carrier ring 36 and a second carrier ring 37 are fixedly connected to the two cleaning brushes 35 respectively. The first carrier ring 36 and the second carrier ring 37 are detachably installed on the processing box 2 by fixing bolts 38 to clean the wire passing through the processing box 2.Fewer abrasive particles adhere to the surface of the wire, resulting in the wire sliding out of the processing box 2.

[0042] It should be further explained that the left and right ends of the base frame 1 are respectively equipped with a lead wire structure and a winding structure. Both the winding structure and the lead wire structure include a covering assembly frame 12. A first moving frame 13 and a second moving frame 14 are slidably connected to each of the two covering assembly frames 12. Each of the two covering assembly frames 12 is equipped with a shifting servo motor and a bidirectional threaded screw 15. The two shifting servo motors are respectively connected to the two bidirectional threaded screws 15. The two first moving frames 13 are respectively threaded to the two bidirectional threaded screws 15. The two second moving frames 14 are respectively threaded to the two bidirectional threaded screws 15. A first lifting frame 16 is slidably connected to each of the two first moving frames 13. A second lifting frame 16 is slidably connected to each of the two second moving frames 14. 7. Electric telescopic rods are installed at the bottom ends of the two first movable frames 13 and the two second movable frames 14. The telescopic rods of the four electric telescopic rods are respectively connected to the two first lifting frames 16 and the two second lifting frames 17. A first guide half-roller 18 and a first winding half-roller 19 are rotatably connected to the two first lifting frames 16, and a second guide half-roller 20 and a second winding half-roller 21 are rotatably connected to the two second lifting frames 17. Synchronous servo motors are installed on both the two first lifting frames 16 and the two second lifting frames 17. The four synchronous servo motors are driven by the synchronous rotation of the first guide half-roller 18, the second guide half-roller 20, the first winding half-roller 19, and the second winding half-roller 21. The first winding half-roller 19 and... Both the second winding half-rollers 21 are equipped with a tensioning / loosening structure. Each tensioning / loosening structure includes a central connecting frame 22, a first opening plate 23, and a second opening plate 24. The two central connecting frames 22 are fixedly connected to one of the two first lifting frames 16 closest to the right and one of the two second lifting frames 17 closest to the right, respectively. Each central connecting frame 22 is equipped with an electric drive rod. Each electric drive rod has a first drive rope 25 and a second drive rope 26 mounted on its drive rod. The two first drive ropes 25 are connected to the two first opening plates 23, and the two second drive ropes 26 are connected to the two second opening plates 24, respectively. Both the first winding half-rollers 19 and the second winding half-rollers 21 are fixedly connected to... The first guide plate 27 and the second guide plate 28 are used to guide the two first drive ropes 25, respectively. The two first guide plates 27 are used to guide the two second drive ropes 26, respectively. The two first opening plates 23 are rotatably connected to the first winding half roller 19 and the second winding half roller 21, respectively. The two second opening plates 24 are rotatably connected to the first winding half roller 19 and the second winding half roller 21, respectively. The cooperation between the lead wire structure and the winding structure facilitates the guidance, winding, and storage of the processed wire, realizes wire driving and guidance, ensures the smooth progress of wire grinding, and has good practicality. Connecting plates 29 are fixedly connected to both the two first opening plates 23 and the two second opening plates 24.Four return springs 30 are fixedly connected inside both the first winding half-roller 19 and the second winding half-roller 21. Each of the four return springs 30 is connected to one of the four connecting plates 29. Two first drive ropes 25 and two second drive ropes 26 are fixedly connected to the four connecting plates 29. Connecting frames 31 are rotatably connected to the drive rods of both electric drive rods. The two first drive ropes 25 and the two second drive ropes 26 are respectively connected to the two connecting frames 31. This demonstrates the specific structure of the driving and reset mechanism for the first opening plate 23 and the second opening plate 24, ensuring the synchronization of the first opening plate 23 and the second opening plate 24. For smooth resetting and closing after drive failure, both the first winding half-roller 19 and the second winding half-roller 21 are provided with rope-threading opening slots 32. After the wire to be processed has completely passed through the threading opening 32, external wire-like objects such as iron wire or strip wire are threaded through the rope-threading opening slots 32 into the space formed by the cooperation of the first opening plate 23 and the second opening plate 24. This forms a ring winding of the wire wound on the first winding half-roller 19 and the second winding half-roller 21. Then, the two ends of the wire-like object are connected to each other, thus achieving the bundling of the processed wire into a coil.

[0043] In this embodiment, the servo motor, electric telescopic rod, synchronous servo motor, electric drive rod, and electric adjustment rod are all commercially available, conventional devices known to those skilled in the art. They can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here. Furthermore, the servo motor, electric telescopic rod, synchronous servo motor, electric drive rod, and electric adjustment rod are equipped with matching control terminals, and control programs are written into the control terminals.

[0044] In summary, the working principle of this grinding device for the external surface of wire is as follows: First, place the grinding device at the desired location. Then, connect the shifting servo motor, electric telescopic rod, synchronous servo motor, electric drive rod, and electric adjusting rod to their respective control circuits relative to the control terminal according to their instruction manuals. Simultaneously, install corresponding first automatic control switches for multiple fixed coils 6 and corresponding second automatic control switches for multiple lifting coils 8. Both the first and second automatic control switches are controlled by the control terminal. Finally, connect the control terminal to the external municipal power supply line. Through the control terminal, the power-on control of the shifting servo motor, electric telescopic rod, synchronous servo motor, electric drive rod, and electric adjusting rod can be achieved. The control terminal can also control the on / off power supply and current intensity of the fixed coils 6 and lifting coils 8. Afterwards, the grinding device is installed inside the processing box 2. Abrasive is introduced, and the abrasive material is selected to be attracted by a magnetic field. The abrasive can be added by removing the filter plate 10 and inserting it through the installation port of the filter plate 10, or by inserting it through the wire insertion port 3. Then, the wire to be processed is guided by the first guide half roller 18 and the second guide half roller 20 and then inserted into the wire insertion port 3. After the wire has completely passed through the processing box 2, the wire end is installed on either the first winding half roller 19 or the second winding half roller 21. Next, multiple fixed coils 6 are energized, so that the multiple fixed coils 6 cooperate with multiple fixed conductors 7 to form multiple fixed electromagnetic fields. The multiple fixed electromagnetic fields cooperate to form a magnetic field covering the upper part of the processing box 2. Then, multiple lifting coils 8 are energized, and the multiple lifting coils 8 cooperate with multiple lifting coils 8 to form multiple lifting electromagnetic fields. The multiple lifting electromagnetic fields cooperate to form a complete magnetic field covering the space between the two lifting boxes 5, and then the whole structure forms a vertical magnetic field covering the space.

[0045] Furthermore, the electric adjusting rod is then controlled to achieve the reciprocating up-and-down movement of the synchronous frame 33. The synchronous frame 33 drives the two lifting boxes 5 to reciprocate up and down synchronously. When the synchronous frame 33 moves down to its limit position, the abrasive material in the lower part of the processing box 2 can be attracted by the vertical magnetic field. When the lifting box 5 moves up to its limit position, the abrasive material attracted by the vertical magnetic field will also enter the upper magnetic field. Then, the power supply to the multiple lifting coils 8 is cut off, and the lifting box 5 is controlled to fall, so that the abrasive material lifted by the vertical magnetic field can enter the upper magnetic field. In this way, the abrasive material located at the bottom of the processing box 2 can be continuously moved up and down by the repeated up and down movement of the lifting box 5. The wire is lifted into the magnetic field covering the storage box. Once the abrasive has accumulated to a certain extent within the magnetic field, the four synchronous servo motors are activated to synchronously drive the first winding half-roller 19 and the second winding half-roller 21, achieving winding and traction of the wire. Before the synchronous rotation of the first winding half-roller 19 and the second winding half-roller 21, both electric drive rods operate to open the two first opening plates 23 and the two second opening plates 24 via the first drive rope 25 and the second drive rope 26. With the synchronous rotation of the first winding half-roller 19 and the second winding half-roller 21, the wire continuously passes through the processing box 2. The wire continuously passing through processing box 2 undergoes a grinding process under the influence of abrasive particles located within the magnetic field covering the box. The magnetic field attracts and positions the abrasive particles, allowing them to overcome friction and change position relative to the wire, thus grinding the wire surface. However, as the wire moves from left to right during the grinding process, the abrasive particles within the magnetic field inevitably move from left to right within the processing box 2 due to friction with the wire. This transfer of some abrasive particles from left to right creates space for new particles to enter the magnetic field covering the box. The abrasive provides a space to hold it. During the movement of the abrasive to the right, when the abrasive moves to the right side of the storage box, the magnetic force of the magnetic field covering it weakens. Therefore, the abrasive can fall back into the lower part of the processing box 2 under its own gravity. For the abrasive adhering to the wire, it will be separated from the wire by the cleaning brush 35 before the wire is removed from the processing box. The cleaning brush 35 can be replaced after wear and tear. Furthermore, due to the setting of the filter plate 10, the abrasive can be guided and the dust contained in the abrasive can be screened out from the wire. In this way, the entire outer ring of the wire can be ground.

[0046] Furthermore, during the wire processing, the first guide half-roller 18 and the second guide half-roller 20 cooperate to form a guide, as shown in the attached figure. Figure 9The state shown is one of the guiding states of the first guide half-roller 18 and the second guide half-roller 20. The first guide half-roller 18 and the second guide half-roller 20 can also be adjusted to the following state by working in conjunction with the corresponding shift servo motors and electric telescopic rods. Figure 16 In the state shown, the wire to be processed passes through the area between the first guide half-roller 18 and the second guide half-roller 20. The first guide half-roller 18 and the second guide half-roller 20 rotate relative to each other to guide the wire. At the same time, the first winding half-roller 19 and the second winding half-roller 21 can also be adjusted to the position shown in the attached figure by working in conjunction with the matching shift servo motor and electric telescopic rod. Figure 16 In the state shown, the first winding half-roller 19 and the second winding half-roller 21 can be used as two independent winding and storage structures for the processed wire. After the wire is processed, external wire-like objects such as iron wire or strip wire are passed through the rope-passing opening slot 32 into the space formed by the cooperation of the first opening plate 23 and the second opening plate 24. This forms a ring winding of the wire wound on the first winding half-roller 19 and the second winding half-roller 21. Then, the two ends of the wire-like object are connected to each other, thus achieving the bundling of the processed wire into a coil. After the wire is bundled, the corresponding first opening plate 23 and the second opening plate 24 are reset and closed. After this, a certain winding gap is formed between the wound wire on the first winding half-roller 19 and the second winding half-roller 21. This facilitates the removal of the coiled wire. Regarding the phrase "after the abrasive has accumulated to a certain extent within the magnetic field covering it," the accumulation of abrasive is defined as the abrasive forming a full ring of coverage over the wire passing through the processing box 2. Furthermore, the magnetic field covering it can be controlled by adjusting the current strength within multiple fixed coils 6, ensuring a gradually increasing and then stabilizing distribution from left to right. This facilitates better entry of the abrasive lifted by the vertical magnetic field above the inclined arc-shaped support plate within the processing box 2, increasing the local filling density of the abrasive within the processing box 2 and ensuring the processing effect of the wire. Simultaneously, the vertical magnetic field covering it can also be controlled by adjusting the current strength within multiple moving coils, ensuring a gradually increasing distribution from bottom to top. Even when there is less abrasive below the processing box 2, the amount of abrasive lifted by the vertical magnetic field in a single operation can still be guaranteed.
