Description

Technical Field

[0001] The utility model relates to the technical field of copper rod production, in particular to a copper rod guide bend guide wheel fixing device. Background Art

[0002] In the copper rod continuous casting and rolling production line, the formed copper rod will be guided by the bending guide wheel at the bend before being wound. The bending guide wheel is used to guide the direction of the copper rod. Due to the friction between the bending guide wheel and the copper rod, it will wear quickly, so the bending guide wheel needs to be replaced frequently.

[0003] In the prior art, the bend pipe guide wheel is installed in the installation groove body through the guide wheel bearing, the fixed axis and the fixed nut, and a gasket is required to be placed between the inner ring of the guide wheel bearing and the inner wall of the installation groove body, and the fixed axis passes through the gasket. During installation, the fixed axis needs to be passed through the hole of the installation groove body, the gasket and the inner ring of the bearing. During the installation process, the gasket is not easy to be placed in the installation groove body, and the gasket is easy to fall off during the installation process, which is inconvenient to install. In addition, the bend pipe guide wheel is easily affected by the axial force when rotating, which will cause squeezing of the gasket. When rotating at high speed, the bend pipe guide wheel will swing and cause accelerated wear. Utility Model Content

[0004] The invention can solve the technical problem of overcoming the existing defects and provide a copper rod guide bend guide wheel fixing device, improves the original two gaskets into two limit shaft sleeve assemblies, the bearing inner sleeve of the limit shaft sleeve assembly is installed in the inner ring of the guide wheel bearing, the guide wheel bearing is installed in the wheel hole of the bend guide wheel, and the fixed axis passes through the bearing inner sleeve to install the bend guide wheel. Since the bearing inner sleeve is first installed on the inner side of the guide wheel bearing, the gasket will no longer fall off when the bend guide wheel is installed in the installation groove body, which is convenient for installing and replacing the bend guide wheel, and is conducive to reducing the difficulty of installing and replacing the bend guide wheel and improving the installation and replacement efficiency of the bend guide wheel. The sleeve clamping mechanism can use the limit retaining ring to keep the bend guide wheel and the guide wheel bearing stably in the middle of the installation groove body, and the bend guide wheel will not contact the inner wall of the installation groove body after being subjected to force, so as to avoid the bend guide wheel from swinging during high-speed rotation, reduce the wear rate of the bend guide wheel, and be conducive to extending the service life of the bend guide wheel, reduce costs, and effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a copper rod guide bend guide wheel fixing device, comprising a mounting trough, a bend guide wheel, and a guide wheel bearing, wherein the bend guide wheel is provided in the mounting trough, and a guide wheel bearing is installed in a wheel hole in the middle of the bend guide wheel, and further comprising:

[0006] There are two limiting sleeve assemblies, and the two limiting sleeve assemblies are respectively sleeved on the left and right ends of the inner side of the guide wheel bearing;

[0007] The guide wheel supports a fixed assembly, which includes a fixed axis. The fixing axis is inserted into the mounting groove body, and the fixed axis passes through the inner sides of the two limiting sleeve assemblies.

[0008] First install the guide wheel bearing in the wheel hole of the bent pipe guide wheel, then pre-install the limit sleeve assembly on the left and right ends of the inner side of the guide wheel bearing, then place the bent pipe guide wheel into the installation position in the installation slot, pass the fixed axis through the axis hole on one side of the installation slot, and then pass the fixed axis through the axis hole on the other side of the installation slot through the limit sleeve assembly. The fixed axis uses the limit sleeve assembly to support the installation of the guide wheel bearing, thereby completing the installation of the bent pipe guide wheel.

[0009] Furthermore, the limit sleeve assembly includes a limit ring, a tapered extrusion sleeve, and a bearing inner sleeve. Two bearing inner sleeves are respectively sleeved on the left and right ends of the inner side of the guide wheel bearing. The two bearing inner sleeves are respectively integrally connected to two tapered extrusion sleeves at one end located on the outer side of the guide wheel bearing, and the two tapered extrusion sleeves are respectively integrally connected to two limit rings at one end away from the guide wheel bearing. The fixed axis passes through the inner side of the two bearing inner sleeves. The outer side of the bearing inner sleeve cooperates with the inner side of the inner ring of the guide wheel bearing, so that the limit sleeve assembly can be installed on the inner side of the guide wheel bearing. The provision of the tapered extrusion sleeve can maintain a gap between the side of the limit ring and the side of the guide wheel bearing, thereby preventing the limit ring from frictionally contacting the outer ring of the guide wheel bearing and wearing the guide wheel bearing.

[0010] Furthermore, the outer diameter of one end of the tapered extrusion sleeve close to the limit ring is larger than the outer diameter of the other end, and the inner diameters of the left and right ends of the tapered extrusion sleeve are the same as the inner diameter of the bearing inner sleeve.

[0011] Furthermore, the guide wheel support fixing assembly further includes fixing nuts, and two fixing nuts are respectively threadedly connected to the positions of the two ends of the fixed axis located on both sides of the installation slot. The fixing nuts fix the two ends of the fixed axis to prevent the fixed axis from moving relative to the installation slot.

[0012] Furthermore, it also includes a sleeve clamping mechanism, which includes a sleeve clamping ring, a lateral sliding limit assembly and a clamping assembly. The fixed axis is located on both sides of the installation groove body and is movably sleeved with two sleeve clamping rings. The two limit rings are in contact with the two sleeve clamping rings on the side away from the bend guide wheel, and each sleeve clamping ring is connected to a lateral sliding limit assembly and a clamping assembly. The lateral sliding limit assembly limits the sleeve clamping ring so that the sleeve clamping ring can only move along the fixed axis. The clamping assembly pushes the sleeve clamping ring to fit tightly against the limit ring. With the help of the limit ring, the bend guide wheel and the guide wheel bearing are stably located in the middle of the installation groove body, preventing the bend guide wheel and the guide wheel bearing from shifting in the installation groove body.

[0013] Furthermore, the lateral sliding limit assembly includes an ear plate and a guide rod. Each sleeve clamping ring is fixedly connected to a side of the ear plate. The ear plate is fixedly connected to one end of the guide rod. The guide rod is parallel to the fixed axis and is slidably connected to the guide hole on the side of the mounting groove. The ear plate is used to mount the guide rod, which guides the sleeve clamping ring so that the sleeve clamping ring can only move left and right along the guide rod.

[0014] Furthermore, the clamping assembly includes a convex plate, a mounting bearing, a stud, a handwheel and a control nut, wherein the side of each sleeve clamping ring is fixedly connected to a convex plate, the convex plate is rotatably connected to one end of the stud through the mounting bearing, the stud is parallel to the fixed axis, the side of the mounting groove body is fixedly connected to the control nut corresponding to the position of the stud, the stud is threadedly connected to the control nut, and the end of the stud located outside the mounting groove body is fixedly connected to the handwheel. By rotating the stud clockwise with the help of the handwheel, the thread action of the stud and the control nut can push the sleeve clamping ring close to the limit ring with the help of the convex plate, and by rotating the stud counterclockwise with the help of the handwheel, the thread action of the stud and the control nut can make the sleeve clamping ring leave the limit ring with the help of the convex plate, thereby the clamping assembly can control the position of the two sleeve clamping rings on the fixed axis, and can also change the left and right relative positions of the bend guide wheel and the guide wheel bearing in the mounting groove body with the help of the limit ring, so that the bend guide wheel can cooperate with the copper rod more smoothly and guide the copper rod better.

[0015] Furthermore, the pressing assembly further comprises friction protrusions, and the friction protrusions are arranged in an annular array on the outer circumference of the hand wheel. The arrangement of the friction protrusions facilitates gripping the hand wheel and is conducive to rotating the hand wheel.

[0016] Compared with the prior art, the copper rod guide bend guide wheel fixing device has the following beneficial effects:

[0017] 1. The original two gaskets are improved into two limiting sleeve assemblies. The bearing inner sleeve of the limiting sleeve assembly is installed in the inner ring of the guide wheel bearing. The guide wheel bearing is installed in the wheel hole of the bent pipe guide wheel. The fixed axis passes through the bearing inner sleeve to install the bent pipe guide wheel. Since the bearing inner sleeve is first installed on the inner side of the guide wheel bearing, the gasket will no longer fall off when the bent pipe guide wheel is installed in the installation groove body, which facilitates the installation and replacement of the bent pipe guide wheel, reduces the difficulty of installation and replacement of the bent pipe guide wheel, and improves the installation and replacement efficiency of the bent pipe guide wheel.

[0018] 2. The sleeve clamping mechanism can use the limit ring to keep the pipe bending guide wheel and the guide wheel bearing stable in the middle of the installation groove body. The pipe bending guide wheel will not be subjected to lateral force and contact with the inner wall of the installation groove body, avoiding the pipe bending guide wheel from swinging during high-speed rotation, reducing the wear rate of the pipe bending guide wheel, and helping to extend the service life of the pipe bending guide wheel and reduce costs.

DETAILED DESCRIPTION

[0026] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] For example 1, please refer to Figures 1 to 6 The utility model provides a technical solution: a copper rod guide bend guide wheel fixing device, comprising a mounting trough 1, a bend guide wheel 2, and a guide wheel bearing 3. The bend guide wheel 2 is arranged in the mounting trough 1, and the guide wheel bearing 3 is installed in the wheel hole in the middle of the bend guide wheel 2. The device also includes a limiting shaft sleeve assembly 5 and a guide wheel support and fixing assembly 4.

[0028] There are two limiting sleeve assemblies 5, and the two limiting sleeve assemblies 5 are respectively sleeved on the left and right ends of the inner side of the guide wheel bearing 3;

[0029] The guide wheel support fixing assembly 4 includes a fixed axis 41 . The fixed axis 41 is inserted into the mounting groove 1 and passes through the inner sides of the two limiting sleeve assemblies 5 .

[0030] The limiting sleeve assembly 5 includes a limiting retaining ring 51, a conical extrusion sleeve 52, and a bearing inner sleeve 53. Two bearing inner sleeves 53 are respectively sleeved on the left and right ends of the inner side of the guide wheel bearing 3. The two bearing inner sleeves 53 are located on the outer side of the guide wheel bearing 3 and are integrally connected to two conical extrusion sleeves 52 at one end, and the two conical extrusion sleeves 52 are integrally connected to the end away from the guide wheel bearing 3. The fixed axis 41 passes through the inner side of the two bearing inner sleeves 53.

[0031] The outer diameter of one end of the tapered extrusion sleeve 52 close to the limit ring 51 is larger than the outer diameter of the other end, and the inner diameters of the left and right ends of the tapered extrusion sleeve 52 are the same as the inner diameter of the bearing inner sleeve 53 .

[0032] The outer side of the bearing inner sleeve 53 cooperates with the inner side of the inner ring of the guide wheel bearing 3, so the limit sleeve assembly 5 can be installed on the inner side of the guide wheel bearing 3. The setting of the conical extrusion sleeve 52 can allow the side of the limit ring 51 to maintain a gap with the side of the guide wheel bearing 3, thereby avoiding friction between the limit ring 51 and the outer ring of the guide wheel bearing 3 and wearing the guide wheel bearing 3.

[0033] The guide wheel support fixing assembly 4 further includes fixing nuts 42. The two ends of the fixed axis 41 are located on both sides of the mounting trough 1 and are respectively threadedly connected to two fixing nuts 42. The fixing nuts 42 fix the two ends of the fixed axis 41 to prevent the fixed axis 41 from moving relative to the mounting trough 1.

[0034] First, install the guide wheel bearing 3 in the wheel hole of the bent pipe guide wheel 2, and then pre-install the limiting shaft sleeve assembly 5 on the left and right ends of the inner side of the guide wheel bearing 3, and then place the bent pipe guide wheel 2 into the installation position in the installation groove body 1, and pass the fixed axis 41 through the axis hole on one side of the installation groove body 1, and then pass the fixed axis 41 through the limiting shaft sleeve assembly 5 from the axis hole on the other side of the installation groove body 1. The fixed axis 41 supports the installation of the guide wheel bearing 3 with the help of the limiting shaft sleeve assembly 5, thereby completing the installation of the bent pipe guide wheel 2.

[0035] The original two gaskets are improved into two limiting sleeve assemblies. The bearing inner sleeve 53 of the limiting sleeve assembly is installed in the inner ring of the guide wheel bearing 3. The guide wheel bearing 3 is installed in the wheel hole of the bent tube guide wheel 2. The fixed axis 41 passes through the bearing inner sleeve 53 to install the bent tube guide wheel 2. Since the bearing inner sleeve 53 is first installed on the inner side of the guide wheel bearing 3, the gasket will no longer fall off when the bent tube guide wheel 2 is installed in the installation groove body 1.

[0036] For example 2, please refer to Figures 1 to 6 The present invention provides a technical solution: a copper rod guide bend guide wheel fixing device. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0037] It also includes a sleeve clamping mechanism 6, which includes a sleeve clamping ring 61, a lateral sliding limit assembly and a clamping assembly. The fixed axis 41 is located on both sides of the mounting groove body 1 and is movably sleeved with two sleeve clamping rings 61. The two limit rings 51 contact the two sleeve clamping rings 61 on the side away from the bending guide wheel 2, and each sleeve clamping ring 61 is respectively connected to a lateral sliding limit assembly and a clamping assembly. The lateral sliding limit assembly limits the shaft sleeve clamping ring 61, so that the shaft sleeve clamping ring 61 can only move along the fixed axis 41, and the clamping assembly pushes the shaft sleeve clamping ring 61 to fit tightly against the limiting retaining ring 51. With the help of the limiting retaining ring 51, the bending pipe guide wheel 2 and the guide wheel bearing 3 are stably located in the middle of the mounting groove body 1, avoiding the bending pipe guide wheel 2 and the guide wheel bearing 3 from shifting in the mounting groove body 1, avoiding the use of gaskets, and the bending pipe guide wheel 2 will not deviate in the mounting groove body 1 and contact the inner wall of the mounting groove body 1, thus avoiding the bending pipe guide wheel from swinging during high-speed rotation.

[0038] The lateral sliding limit assembly includes two lugs 62 and two guide rods 63. Each lug 62 is fixedly connected to the side of each sleeve clamping ring 61. The lug 62 is fixedly connected to one end of a guide rod 63. The guide rod 63 is parallel to the fixed axis 41 and is slidably connected to a guide hole in the side of the mounting trough 1. The lugs 62 are used to mount the guide rod 63, which guides the sleeve clamping ring 61, allowing it to move only left and right along the guide rod 63.

[0039] The clamping assembly includes a convex plate 64, a mounting bearing 65, a stud 66, a handwheel 67 and a control nut 69. The side of each sleeve clamping ring 61 is fixedly connected with a convex plate 64. The convex plate 64 is rotatably connected to one end of the stud 66 through the mounting bearing 65. The stud 66 is parallel to the fixed axis 41. The side of the mounting trough body 1 is fixedly connected with a control nut 69 corresponding to the position of the stud 66. The stud 66 is threadedly connected to the control nut 69, and the end of the stud 66 located on the outside of the mounting trough body 1 is fixedly connected with a handwheel 67. By rotating the stud 66 clockwise with the help of the handwheel 67, the threaded action of the stud 66 and the control nut 69 can push the sleeve clamping ring 61 close to the limit ring 51 with the help of the convex plate 64. By rotating the stud 66 counterclockwise with the help of the handwheel 67, the threaded action of the stud 66 and the control nut 69 can make the sleeve clamping ring 61 leave the limit ring 51 with the help of the convex plate 64. In this way, the clamping assembly can control the positions of the two sleeve clamping rings 61 on the fixed axis 41, and can also change the left and right relative positions of the bending guide wheel 2 and the guide wheel bearing 3 in the mounting groove body 1 with the help of the limit ring 51, so that the bending guide wheel 2 can cooperate with the copper rod more smoothly and guide the copper rod better.

[0040] The pressing assembly further includes friction protrusions 68, and the friction protrusions 68 are arranged in an annular array on the outer periphery of the hand wheel 67. The arrangement of the friction protrusions 68 facilitates gripping the hand wheel 67 and facilitates rotation of the hand wheel 67.
