Description

Technical Field

[0001] The utility model relates to the technical field of idler devices, and particularly relates to an idler device. Background Art

[0002] During the production and processing of steel wires, idlers are required to support and transmit the steel wires. For example, an idler device is used to support and transmit the steel wires, so that the steel wires enter the quenching operation from the open hearth furnace operation. The existing idler devices mainly support and transmit large-diameter steel wires. When they support and transmit small-diameter steel wires, it will cause the small-diameter steel wires to take a long time in the quenching operation. Specifically, the immersion area of the small-diameter steel wires in the quenching operation is large and the time of the immersion step is long, thus affecting the accuracy of the small-diameter steel wires. Therefore, there is an urgent need for an idler device to solve the above problems. Summary of the Utility Model

[0003] In order to solve the technical problem that when the existing idler device supports and transmits small-diameter steel wires, it will cause the small-diameter steel wires to take a long time in the quenching operation, the utility model provides an idler device with a simple structure. When the support roller supports and transmits small-diameter steel wires, the immersion time of the small-diameter steel wires is shortened, and finally the accuracy of the small-diameter steel wires is ensured.

[0004] The utility model provides an idler device, which includes an idler main body. The idler main body is placed in an installation groove on the working ground. The idler main body includes a semi-cylindrical base and a support roller. The arc surface of the semi-cylindrical base contacts the bottom of the installation groove. The support roller is arranged on one side above the semi-cylindrical base. A fixing block is also arranged between the semi-cylindrical base and the support roller. The outer diameter of the semi-cylindrical base is smaller than the inner diameter of the installation groove and larger than the outer diameter of the support roller. The semi-cylindrical base is clamped into the installation groove, and the support roller is located above the installation groove. The support roller supports and transmits small-diameter steel wires. The outer diameter of the semi-cylindrical base is larger than the outer diameter of the support roller, which makes the immersion area of the small-diameter steel wires in the immersion step smaller when the small-diameter steel wires passing through the support roller are in the quenching operation. Therefore, the immersion time of the small-diameter steel wires is shortened, and finally the accuracy of the small-diameter steel wires is ensured.

[0005] Further, an opening is arranged on the side wall of the installation groove. A connecting rod is arranged at the center of the end of the semi-cylindrical base, and one end of the connecting rod passes out through the opening. The fixing block is arranged on one side above the semi-cylindrical base. A fixing groove is arranged on the fixing block. The lower part of the support roller is arranged in the fixing groove, and the upper part of the support roller is located above the installation groove. One end of the connecting rod passes out through the opening, and people can rely on the connecting rod to adjust the position of the idler main body, which further facilitates the operation of people. The fixing groove on the fixing block realizes the stable connection between the semi-cylindrical base and the support roller.

[0006] Furthermore, the idler device further includes a limiting component, the limiting component includes a bolt and a screw rod. The bolt is movably arranged on the working ground and is located above the connecting rod. The screw rod is arranged on the connecting rod and is perpendicular to the connecting rod. One end of the bolt abuts against one end of the screw rod.

[0007] Furthermore, a base is arranged on the working ground and a base plate is arranged on the base. The base plate is located above one side of the connecting rod. A first nut is arranged on the base plate and the bolt is threadedly connected to the first nut. The tail of the bolt abuts against the head of the screw rod.

[0008] Furthermore, a second nut is threadedly connected to the screw rod. The tail of the bolt abuts against the head of the screw rod or the second nut located at the head of the screw rod. When the height of the screw rod is not enough, the second nut is threadedly moved to the head of the screw rod. At this time, one end of the bolt abuts against the second nut located at the head of the screw rod, so that the adjustment range of the height of the supporting roller becomes larger.

[0009] Furthermore, the idler device further includes a cylinder arranged on the working ground. The telescopic rod of the cylinder is fixedly connected to the end of the connecting rod through a clamping block. When the cylinder is started, it will drive the connecting rod, the semi-cylindrical base and the supporting roller to vibrate slightly. This vibration will make the coke deposits on the supporting roller fall off. People don't need to manually clean the coke deposits on the supporting roller, which also improves the service life and working efficiency of the supporting roller.

[0010] Furthermore, two clamping ports are arranged on the clamping block. The telescopic rod of the cylinder and one end of the connecting rod are respectively clamped into the two clamping ports. The two clamping ports on the clamping block realize the stable connection between the telescopic rod of the cylinder and one end of the connecting rod.

[0011] Furthermore, the idler device further includes a gasket. The gasket is arranged on the wall of the installation groove and contacts with the semi-cylindrical base. The gasket can further keep the semi-cylindrical base stable in the installation groove and avoid the wear of the semi-cylindrical base after long-term use.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] 1. In the initial state, the semi-cylindrical base is in a horizontal state in the installation groove, and the supporting roller is located above the installation groove. The small-diameter steel wire is supported and transmitted by the supporting roller. The outer diameter of the semi-cylindrical base is larger than the outer diameter of the supporting roller, and the immersion length of the small-diameter steel wire becomes smaller. This makes the immersion area of the small-diameter steel wire passing through the supporting roller smaller during the quenching operation, so the immersion time of the small-diameter steel wire is shortened, and finally the accuracy of the small-diameter steel wire is ensured.

[0014] 2. When the supporting roller needs to support and transfer small-diameter steel wires of different sizes, since the immersion time requirements for small-diameter steel wires of different sizes are different, people can manually adjust the position of the semi-cylindrical base in the installation groove to make the semi-cylindrical base in an inclined state. At this time, the position of the supporting roller moves upward relative to the initial supporting roller, thereby causing the small-diameter steel wire to move upward, and the immersion area of the small-diameter steel wire in the immersion step becomes larger to meet the immersion time requirements for small-diameter steel wires of different sizes.

[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0022] As Figures 1 to 4 shown, a roller device includes a roller main body. The roller main body is placed in an installation groove 8 on the working ground. The installation groove 8 in this embodiment is arranged between the open hearth operation and the quenching operation. The roller main body includes a semi-cylindrical base 1 and a supporting roller 2. The arc surface of the semi-cylindrical base 1 contacts the bottom of the installation groove 8. The supporting roller 2 is arranged above one side of the semi-cylindrical base 1. The outer diameter of the semi-cylindrical base 1 is slightly smaller than the inner diameter of the installation groove 8 and larger than the outer diameter of the supporting roller 2. The semi-cylindrical base 1 just fits into the installation groove 8. The supporting roller 2 (i.e., the upper part of the supporting roller 2) is located above the installation groove 8. The fixed block 3 and the lower part of the semi-cylindrical base 1 are located in the installation groove 8.

[0023] In the initial state, the semi-circular base 1 is in a horizontal state in the installation groove 8, that is, the semi-circular base 1 and the installation groove 8 are on the same horizontal plane, and the support roller 2 is located above the installation groove 8. The support roller 2 supports and transports the small-diameter steel wire 9. The outer diameter of the semi-circular base 1 is larger than the outer diameter of the support roller 2, and the immersion length of the small-diameter steel wire 9 becomes smaller. This makes the immersion area of the small-diameter steel wire 9 passing through the support roller 2 smaller during the quenching operation, so the immersion time of the small-diameter steel wire 9 is shortened, and finally the accuracy of the small-diameter steel wire 9 is ensured.

[0024] When the support roller 2 needs to support and transport small-diameter steel wires 9 of different sizes, since the immersion time requirements for small-diameter steel wires 9 of different sizes are different, people can manually adjust the position of the semi-circular base 1 in the installation groove 8 to make the semi-circular base 1 in an inclined state. At this time, the position of the support roller 2 relative to the initial support roller 2 moves upward, and then the small-diameter steel wire 9 moves upward, and the immersion area of the small-diameter steel wire 9 in the immersion step becomes larger to meet the immersion time requirements of small-diameter steel wires 9 of different sizes. Specifically, the semi-circular base 1 rotates clockwise, and the support roller 2 moves upward.

[0025] The idler roller device of this embodiment has a simple structure. When the support roller 2 supports and transports the small-diameter steel wire 9, the immersion length of the small-diameter steel wire 9 becomes smaller, shortening the immersion time of the small-diameter steel wire 9, and finally ensuring the accuracy of the small-diameter steel wire 9. At the same time, the immersion area of the small-diameter steel wire 9 in the immersion step can be adjusted, so that it can meet the immersion time requirements of small-diameter steel wires 9 of different sizes.

[0026] As an implementable manner, an opening is provided on the side wall of the installation groove 8, and a connecting rod 11 is provided at the center of the end of the semi-circular base 1, and one end of the connecting rod 11 passes out of the opening. One end of the connecting rod 11 passes out of the opening, and people can rely on the connecting rod 11 to adjust the position of the idler roller main body, which further facilitates the operation of people.

[0027] As an implementable manner, the fixing block 3 is provided on the upper side of the semi-circular base 1, a fixing groove is provided on the fixing block 3, the support roller 2 (that is, the lower part of the support roller 2) is arranged in the fixing groove, and the upper part of the support roller 2 is located above the installation groove 8. The fixing groove on the fixing block 3 realizes the stable connection between the semi-circular base 1 and the support roller 2.

[0028] As an implementable manner, the idler roller device further includes a limiting component. The limiting component includes a bolt 4 and a screw rod 5. The bolt 4 is movably arranged on the working ground and is located above the connecting rod 11. The screw rod 5 is arranged on the connecting rod 11 and is perpendicular to the connecting rod 11. One end of the bolt 4 abuts against one end of the screw rod 5. See Figure 3, when adjusting the position of the idler main body, when the bolt 4 moves away from the screw rod 5 (to the left) or towards the screw rod 5 (to the right), since one end of the bolt 4 abuts against one end of the screw rod 5, the bolt 4 causes the screw rod 5 to deflect clockwise or counterclockwise. Also, since the screw rod 5 is arranged on the connecting rod 11, after the position of the screw rod 5 changes, the position of the semi-cylindrical base 1 in the installation groove 8 and the height of the support roller 2 can be adjusted.

[0029] As an implementable mode, a base 6 is arranged on the working ground and a base plate 61 is arranged on the base 6. The base plate 61 is located above one side of the connecting rod 11. A first nut 41 is arranged on the base plate 61 and the bolt 4 is threadedly connected to the first nut 41. The tail of the bolt 4 abuts against the head of the screw rod 5. Through the first nut 41 on the base plate 61, the bolt 4 is threadedly connected to the first nut 41, and the bolt 4 can move away from the screw rod 5 (to the left) or towards the screw rod 5 (to the right). Among them, when the nut of the bolt 4 contacts the first nut 41, the bolt 4 can no longer move to the right.

[0030] As an implementable mode, a second nut 51 is threadedly connected to the screw rod 5. The tail of the bolt 4 abuts against the head of the screw rod 5 or the second nut 51 located at the head of the screw rod 5. By adding the second nut 51, when the height of the screw rod 5 is insufficient, the second nut 51 moves to the head of the screw rod 5, and the height of the screw rod 5 and the second nut 51 is greater than the original height of the screw rod 5, and the overall height increases. When the height of the screw rod 5 is insufficient, the second nut 51 is threadedly moved to the head of the screw rod 5. At this time, one end of the bolt 4 abuts against the second nut 51 located at the head of the screw rod 5, so that the adjustment range of the support roller 2 becomes larger. When the second nut 51 is not used, the second nut 51 is threadedly moved to other positions of the screw rod 5.

[0031] As an implementable mode, the idler device further includes a cylinder 7 arranged on the working ground. The telescopic rod of the cylinder is fixedly connected to the end of the connecting rod 11 through a clamping block 71. Usually, after the small-diameter steel wire 9 passes through the open hearth furnace operation, there are coking substances on the small-diameter steel wire 9. When the small-diameter steel wire 9 is supported and transmitted by the support roller 2, the coking substances can be scraped off. However, there is a problem that coking substances will remain on the support roller 2. In this embodiment, when the cylinder 7 is started, it will drive the connecting rod 11, the semi-cylindrical base 1 and the support roller 2 to vibrate slightly, that is, the idler main body has a slight vibration in its length direction. This vibration will cause the coking substances on the support roller 2 to be shaken off, and people do not need to manually clean the coking substances on the support roller 2, which also improves the service life and working efficiency of the support roller 2.

[0032] As an implementable manner, two clamping interfaces are provided on the clamping block 71, and one end of the telescopic rod of the cylinder and the connecting rod 11 are respectively clamped into the two clamping interfaces. The two clamping interfaces on the clamping block 71 realize the stable connection between one end of the telescopic rod of the cylinder and the connecting rod 11.

[0033] As an implementable manner, the idler device further includes a gasket, and the gasket is arranged on the wall of the installation groove 8 and contacts the semi-cylindrical base 1. The gasket can further keep the semi-cylindrical base 1 stable in the installation groove 8 and prevent the semi-cylindrical base 1 from being worn after long-term use. The fixing block 3 in this embodiment also contacts the gasket.

[0034] The above-described embodiments are only the preferred embodiments of the present invention, which are only used to explain the present invention and do not limit the scope of implementation of the present invention. For those skilled in the art of this technology, other implementation manners can of course be easily made by means of replacement or change according to the technical content disclosed in this specification. Therefore, all changes and improvements made to the principle and process conditions of the present invention should be included within the scope of the patent application of the present invention.
