Description

Technical Field

[0001] The present application relates to the technical field of rolling mill base friction rings, and in particular to a rolling mill base friction ring for copper tube processing. Background Art

[0002] When copper tubes are processed, they need to be processed by a rolling mill so that they can be processed into shape. A rolling mill is a device that realizes metal rolling. When the metal passes through the roller head of the rolling mill, it can be processed into shape by extrusion and other methods.

[0003] The roll head of the rolling mill currently on the market is connected to the friction ring through the roll head shaft. The friction ring is arranged on the base of the rolling mill, which can make the roll head shaft rotate at the bottom through the friction ring, thereby realizing the processing of metal by the roll head. However, the conventional friction ring directly rubs against the base, resulting in great wear of the friction ring and the base during the processing, making it easy for the roll head shaft to jump after long-term use, causing errors. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a friction ring for a rolling mill base for copper tube processing, which has the advantages of not being easy to jump and solves the problem of easy jumping.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a rolling mill base friction ring for copper tube processing, comprising a rolling mill base body and a roll head body, a roll head shaft is fixed to the lower end of the roll head body, and an anti-wear component is provided on the outer surface of the roll head shaft;

[0006] The anti-wear component includes a bearing seat, a thrust ball bearing, a buckle block fixedly installed on the outer surface of the thrust ball bearing, and a limit component fixedly installed on the top end of the bearing seat.

[0007] By adopting the above technical solution, the friction ring is replaced by a friction ring composed of a bearing seat and a thrust ball bearing, which can reduce the wear of the roller head shaft and thus reduce the error caused by the runout of the roller head shaft.

[0008] Furthermore, the buckle block is a ring-shaped soft block, the inner side wall of the bearing seat is provided with an annular groove, and the buckle block is clamped to the inner side of the annular groove.

[0009] By adopting the above technical solution, the thrust ball bearing can be embedded and installed on the inner side of the bearing seat through the snap block, so that the thrust ball bearing and the bearing seat can be assembled together.

[0010] Furthermore, the limiting assembly includes a limiting block, two slots, two positioning blocks, two screws, support blocks fixedly mounted at the front and rear ends of the two positioning blocks, and a reset assembly fixedly mounted at the left and right ends of the positioning blocks.

[0011] By adopting the above technical solution, the bearing seat can be limited and positioned, which can prevent the bearing seat and the outer surface of the roller head shaft from loosening and falling off due to the mechanical vibration generated by the rotation of the roller head shaft, so that the friction ring of the thrust ball bearing and the bearing seat can be stably installed on the outer surface of the roller head shaft.

[0012] Furthermore, the limiting block is in a ring shape, and the two slots are respectively opened at the left and right ends of the top of the limiting block.

[0013] By adopting the above technical solution, the limit block can be sleeved and fixed on the outer surface of the roller head shaft.

[0014] Furthermore, through holes are provided at both left and right ends of the lower end of the limiting block, and the positioning block is slidably connected to the inner side of the through holes.

[0015] By adopting the above technical solution, the two positioning blocks can be moved out of the slot through the through hole, so that the two positioning blocks can position and limit the bearing seat, thereby reducing the phenomenon of the bearing seat falling off the outer surface of the roller head shaft.

[0016] Furthermore, two slide grooves are provided on the front and rear walls of the inner cavity of the slot hole, and the support block is slidably connected to the inner side of the slide grooves.

[0017] By adopting the above technical solution, the positioning block can be effectively prevented from falling out of the inner cavity of the slot hole through the front and rear groups of support blocks.

[0018] Furthermore, the reset assembly includes two connecting blocks, two vertical rods, two springs, and a frame plate fixedly mounted on the opposite ends of the two connecting blocks.

[0019] By adopting the above technical solution, when the bottom end of the screw no longer abuts against the top end of the positioning block, the spring is no longer squeezed by the elastic force, so that the spring can push the frame plate to move upward. While the two frame plates move upward, they can drive the positioning block to move upward through the two connecting blocks, so that the positioning block can move into the interior of the slot, so that the two positioning blocks no longer restrict the positioning of the bearing seat.

[0020] Furthermore, a circular hole is provided at the lower end of the two frame plates, and the vertical rod is slidably connected to the inner side of the circular hole.

[0021] By adopting the above technical solution, the frame plate can slide on the outer surface of the vertical rod so that the frame plate can press the spring.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The friction ring of the rolling mill base for copper tube processing is provided with an anti-wear component. By replacing the friction ring with a friction ring composed of a bearing seat and a thrust ball bearing, the wear of the roller head shaft can be effectively reduced, thereby reducing the error caused by the vibration of the roller head shaft. By providing a limit component and a reset component, the bearing seat can be further positioned to limit the mechanical vibration of the bearing seat caused by the rotation of the roller head shaft, thereby reducing the phenomenon that the outer surface of the bearing seat and the roller head shaft becomes loose and falls off, so that the friction ring composed of the thrust ball bearing and the bearing seat can be stably installed on the outer surface of the roller head shaft.

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

[0032] Among them, the snap block 24 is a soft block in the shape of a ring, so that the snap block 24 can be fixed to the outer surface of the thrust ball bearing 23, and the inner wall of the bearing seat 22 is provided with an annular groove, and the snap block 24 is snapped into the inner side of the annular groove, so that when the snap block 24 is snapped into the inner side of the annular groove, the thrust ball bearing 23 can be embedded and installed on the inner side of the bearing seat 22, and the roller head shaft 21 is threadedly connected with the bearing seat 22, so that the roller head shaft 21 can be fixed to the inner side of the bearing seat 22, so that the roller head shaft 21 can be inserted into the inner side of the thrust ball bearing 23, so that the roller head shaft 21 can abut against the inner side wall of the thrust ball bearing 23, and by replacing the friction ring with a friction ring composed of the bearing seat 22 and the thrust ball bearing 23, the wear of the roller head shaft 21 can be reduced, thereby reducing the error caused by the runout of the roller head shaft 21.

[0033] Please refer to the figure Figure 2 and Figure 4 The limiting assembly in this embodiment includes a limiting block 25, two slots 26, two positioning blocks 27, two screws 28, support blocks 29 fixedly installed at the front and rear ends of the two positioning blocks 27, and a reset assembly fixedly installed at the left and right ends of the positioning blocks 27.

[0034] Secondly, the limit block 25 is in a ring shape and is fixed to the outer surface of the roller head shaft 21. Two slots 26 are respectively opened at the left and right ends of the top of the limit block 25. The screw 28 is threadedly connected to the inner side of the slot 26, so that the screw 28 can move inside the slot 26, so that the screw 28 can push the positioning block 27 to move downward in the inner cavity of the slot 26.

[0035] In addition, through holes are provided at both left and right ends of the lower end of the limit block 25, and the positioning block 27 is slidably connected to the inner side of the through hole, so that when the screw 28 abuts against the top end of the positioning block 27, the screw 28 can push the positioning block 27 to move out of the interior of the limit block 25, and a plurality of positioning grooves are provided at the top end of the bearing seat 22. When the two positioning blocks 27 are inserted into the corresponding two positioning grooves, the two positioning blocks 27 can position and limit the bearing seat 22 threadedly connected to the outer surface of the roller head shaft 21, so as to reduce the vibration generated when the roller head shaft 21 drives the roller head body 2 to rotate, causing the bearing seat 22 to loosen and fall off.

[0036] In addition, two slide grooves are provided on the front and rear walls of the inner cavity of the slot hole 26, and the support block 29 is slidably connected to the inner side of the slide groove, so that the support block 29 can slide on the inner side of the slide groove, which can effectively prevent the positioning block 27 and the limit block 25 from falling out of the inner cavity of the slot hole 26.

[0037] See also Figure 4The reset assembly in this embodiment includes two connecting blocks 210, two vertical rods 212, two springs 213, and a frame plate 211 fixedly mounted on the opposite ends of the two connecting blocks 210.

[0038] At the same time, the lower ends of the two frame plates 211 are provided with round holes, the vertical rod 212 is slidably connected to the inner side of the round hole, and the spring 213 is sleeved on the outer surface of the vertical rod 212, so that the vertical rod 212 can limit the spring 213. The two vertical rods 212 are respectively fixed on the left and right ends of the bottom of the inner cavity of the slot hole 26, and the vertical rod 212 can move into the inner side of the frame plate 211 through the round hole, so that the frame plate 211 can squeeze the spring 213.

[0039] In addition, the opposite sides of the two connecting blocks 210 are respectively fixed to the left and right ends of the positioning block 27, so that when the screw rod 28 pushes the positioning block 27 to move downward, the positioning block 27 can drive the two frame plates 211 to move on the outer surface of the vertical rod 212 through the two connecting blocks 210, so that the positioning block 27 can drive the two frame plates 211 to squeeze the spring 213.

[0040] The working principle of the above embodiment is:

[0041] When in use, the thrust ball bearing 23 is clamped to the inner side of the bearing seat 22 through the buckle block 24, so that the thrust ball bearing 23 and the bearing seat 22 can be assembled together, and can be sleeved on the outer surface of the roller head shaft 21. The bearing seat 22 is fixed to the outer surface of the roller head shaft 21 through a threaded connection. By replacing the friction ring with a friction ring assembled by the thrust ball bearing 23 and the bearing seat 22, the wear of the roller head shaft 21 can be reduced, thereby reducing the error caused by the runout of the roller head shaft 21.

[0042] When the bearing seat 22 is fixed to the outer surface of the roller head shaft 21, the top end of the bearing seat 22 abuts against the lower end of the limit block 25, and the screw 28 can be inserted into the inside of the slot 26, and the screw 28 is rotated so that the screw 28 can be threadedly connected with the slot 26, so that the screw 28 can gradually move into the inner side of the slot 26, so that the screw 28 can push the positioning block 27 to move downward, and the positioning block 27 drives the two connecting blocks 210 to move while moving, so that the two connecting blocks 210 can drive the two frame plates 211 to move between the vertical rods 212. The outer surface moves downward, so that the frame plate 211 can squeeze the spring 213 sleeved on the outer surface of the vertical rod 212, so that the positioning block 27 can be moved out of the slot 26 and inserted into the corresponding positioning groove at the top of the bearing seat 22, and the above steps are repeated to move the positioning block 27 on the other side into the corresponding positioning groove, so as to limit the positioning of the bearing seat 22, and reduce the vibration of the bearing seat 22 caused by the rotation of the roller head shaft 21, which may cause the outer surface of the bearing seat 22 and the roller head shaft 21 to loosen and fall off.
