[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides a metal positioning wheel for wire drawing machine to prevent deviation, including a positioning wheel body, wherein the middle parts of both ends of the positioning wheel body are fixedly connected with a threaded tube 5, and the inner cavity of the other end of the threaded tube 5 is threadedly connected with a threaded column 3. Through the arrangement of the threaded tube 5 and the threaded column 3, after the metal positioning wheel is installed, the staff can fine-tune the position of the metal positioning wheel by screwing the threaded tube 5, thereby avoiding disassembly of the metal positioning wheel and improving the installation convenience of the metal positioning wheel.

[0031] The positioning wheel body is a split structure, and the positioning wheel body includes a bearing 4 fixedly connected to the threaded tube 5, a fixed part fixedly connected to the outer ring of the bearing 4, a replacement part 1 and a baffle 2. The replacement part 1 is movably sleeved on the outer ring of the fixed part, and the outer rings at both ends of the replacement part 1 are movably sleeved with baffles 2. The baffle 2, the replacement part 1 and the fixed part are connected through a connecting structure. The ends of the baffle 2, the replacement part 1 and the fixed part are all provided with plug holes 13, and the outer sides of the baffle 2, the replacement part 1 and the fixed part are all provided with positioning lines 20. When the positioning lines 20 on the baffle 2, the replacement part 1 and the fixed part are in an aligned state, the plug holes 13 on the baffle 2, the replacement part 1 and the fixed part are in an aligned state, and the positioning lines 20 can play a positioning function, which is convenient for the staff to assemble the metal positioning wheel.

[0032] The connecting structure includes an insertion rod 18 adapted to the socket 13. The insertion rod 18 is L-shaped. The bottom of the horizontal end of the insertion rod 18 is adapted to the outer wall of the baffle 2. The slot formed by the aligned sockets 13 on the baffle 2, the replacement part 1 and the fixed part is adapted to the vertical end of the insertion rod 18.

[0033] A card slot is provided at the bottom end of the plug rod 18, the bottom of the inner cavity of the socket 13 on the fixed part is connected to the limited block 16 through a spring 1 24, and the top of the inner cavity of the socket 13 on the fixed part is connected to a card block 17 through a spring 23, and the card block 17 is adapted to the card slot, and the telescopic direction of the spring 1 24 and the telescopic direction of the spring 23 are in a mutually perpendicular state, and the telescopic direction of the spring 23 and the insertion direction of the plug rod 18 are in a mutually perpendicular state, and the distance between the card slot and the horizontal end of the plug rod 18 and the distance between the top of the card block 17 and the outer side wall of the baffle 2 The distance values ​​between them are the same. With such a setting, when the insertion rod 18 is inserted into the slot, the insertion rod 18 can squeeze the limit block 16, and the spring 1 24 is in a compressed state. When the bottom of the insertion rod 18 contacts the bottom of the inner cavity of the slot, the card slot and the card block 17 are in an aligned state. Under the action of the rebound force of the spring 23, the insertion rod 18 can be inserted into the card slot to fix the insertion rod 18. At this time, the horizontal end of the insertion rod 18 is tightly fitted with the outer wall of the baffle 2, and the insertion rod 18 is used to realize the connection between the fixing part, the replacement part 1 and the baffle 2.

[0034] The connection structure includes a toothed ring 19, the middle of both ends of the fixed part are movably connected with the toothed ring 19, the outer rings of both ends of the fixed part are movably connected with the rotating rod 15, the rotating rod 15 is circumferentially distributed on the outer side of the end of the fixed part, and one end of the rotating rod 15 is meshed with the toothed ring 19. When the toothed ring 19 rotates, all the rotating rods 15 meshed with the toothed ring 19 rotate. A pull rope 25 is fixedly connected to the inner side of the rotating rod 15, and the other end of the pull rope 25 is fixedly connected to the middle of the clamping block 17. The pull rope 25 can pull the clamping block 17 to move. When the clamping block 17 is separated from the insertion rod 18, under the action of the rebound force of the spring 24, the limit block 16 can push the insertion rod 18 outward, so that the staff can remove the insertion rod 18, and the top of the limit block 16 can limit the clamping block 17 to prevent the clamping block 17 from being inserted into the slot, so as to facilitate the re-fixation of the insertion rod 18.

[0035] The length of the rotating rod 15 is greater than the difference between the outer diameter of the gear ring 19 and the inner diameter of the baffle 2. The baffle 2 and the replacement part 1 can be positioned by the rotating rod 15, which is convenient for assembling the metal positioning wheel.

[0036] The outer side of the end of the fixed part is evenly provided with a receiving groove 14 adapted to the pull rope 25. The setting of the receiving groove 14 facilitates the rotation of the rotating rod 15 to rotate the pull rope 25 to move. When the rotating rod 15 drives the pull rope 25 to move, the pull rope 25 can drive the clamping block 17 to move.

[0037] From the above description of the connection structure, it can be known that when the staff replaces the baffle 2 or the replacement part 1, the staff rotates the two gear rings 19, and the gear rings 19 drive the rotating rod 15 meshing therewith to rotate, and the rotating rod 15 drives the block 17 to move through the pull rope 25 until the block 17 is separated from the plug rod 18. At this time, the end of the rotating rod 15 away from the gear ring 19 contacts the fixed part, and the limiting of the baffle 2 and the replacement part 1 by the rotating rod 15 is released, which facilitates the disassembly and assembly of the baffle 2 and the replacement part 1. When the replacement part 1 and the baffle 2 need to be installed, the staff rotates a gear ring 19, and the rotation of the gear ring 19 resets the rotating rod 15. The rotating rod 15 can limit the baffle 2 and the replacement part 1, which facilitates the staff to install the baffle 2 and the replacement part 1 in sequence.

[0038] The outer surface of the replacement part 1 and the outer surface of the baffle 2 are both wrapped with a thermal pad 22, the outer wall of the baffle 2 is evenly fixedly connected with heat dissipation fins 7, the inner wall of the baffle 2 is fixedly connected with a sealing ring, and the heat dissipation fins 7 are circumferentially distributed on the outer wall of the baffle 2. Through the arrangement of the thermal pad 22 and the heat dissipation fins 7, the heat accumulated on the replacement part 1 can be transferred to the baffle 2 and the heat dissipation fins 7 by using the thermal pad 22, thereby accelerating the heat dissipation of the metal positioning wheel. The thermal pad 22 can be made of graphene.

[0039] The replacement part 1 and the heat-conducting pad 22 connected thereto are evenly provided with oil seepage holes, the fixed part includes a center tube 12 connected to the bearing 4 and a lubrication tube 9 fixedly connected to the outer ring of the center tube 12, the outer wall of the lubrication tube 9 is evenly provided with a receiving groove, the receiving groove is filled with lubricating oil, and the outer wall of the lubrication tube 9 is alternately filled with solid lubricating oil and liquid lubricating oil. Through the setting of the lubrication tube 9, when the metal positioning wheel is in use, the heat accumulated on the replacement part 1 can melt the solid lubricating oil, and the lubricating oil can be transferred to the outer wall of the replacement part 1 through the oil seepage holes, lubricating the friction parts between the replacement part 1 and the wire drawing workpiece, reducing the wear of the replacement part 1 and extending the service life of the metal positioning wheel. When the heat accumulated on the replacement part 1 cannot melt the solid lubricating oil, the liquid lubricating oil is transferred to the outer wall of the replacement part 1 through the oil seepage holes under the action of the centrifugal force of the rotation of the positioning wheel, and the metal positioning wheel can also be lubricated.

[0040] The gear ring 19 is magnetically attracted to the center tube 12 to prevent the position of the gear ring 19 from changing when the metal positioning wheel rotates. A threaded tube 5 is fixedly connected to the outer ring 10 with a fixed ring 10. A pressure sensor 21 is fixed to the outer wall of the fixed ring 10. An alarm 11 is provided on the fixed ring 10. By setting the pressure sensor 21, the rotation stability of the positioning wheel body can be detected. When the positioning wheel body is locally worn, the movement state of the positioning wheel body will become unstable, and the pressing force on the pressure sensor 21 will change. According to this phenomenon, the pressure sensor 21 can be used to detect whether the metal positioning wheel is locally worn, and when the anti-bias metal positioning wheel is worn, the alarm 11 can sound an alarm, which is convenient for the staff to replace the metal positioning wheel in time. The alarm 11 can be an audible and visual alarm.

[0041] In summary: the anti-deviation metal positioning wheel of the wire drawing machine is installed at a suitable position on the wire drawing machine. If the position of the anti-deviation metal positioning wheel needs to be fine-tuned after installation, the staff rotates the threaded tube 5, and the threaded tube 5 moves in the direction of the threaded column 3, thereby realizing the fine-tuning of the installation position of the anti-deviation metal positioning wheel. When the anti-deviation metal positioning wheel is in use, the heat accumulated on the positioning wheel body is transferred to the thermal pad 22 and the heat dissipation fins 7 on the baffle 2 through the thermal pad 22, thereby accelerating the heat dissipation speed of the positioning wheel; and under the combined influence of the centrifugal force of the rotation of the metal positioning wheel and the accumulated deformation heat of the wire drawing workpiece, the lubricating oil is transferred to the outer wall of the metal positioning wheel through the oil seepage holes, thereby reducing the friction between the wire drawing workpiece and the metal positioning wheel, thereby extending the service life of the anti-deviation metal positioning wheel; and when the baffle 2 or the replacement part 1 needs to be replaced, the staff rotates the two gear rings 19, and the gear rings 19 drive the rotation of The rotating rod 15 meshed with it rotates until the end of the rotating rod 15 away from the gear ring 19 contacts the fixed part, thereby releasing the restriction of the rotating rod 15 on the baffle 2 and the replacement part 1, and the pulling rope 25 drives the block 17 to move when the rotating rod 15 rotates. After the rotating rod 15 releases the restriction on the baffle 2 and the replacement part 1, the block 17 is completely separated from the insertion rod 18. Under the action of the rebound force of the spring 24, the spring 24 pushes the insertion rod 18 outward through the limit block 16, so that the staff can remove the insertion rod 18 conveniently. After the insertion rod 18 is removed, the staff can replace the baffle 2 or the replacement part 1.
