Description

Technical Field

[0001] The utility model belongs to the technical field of pinch rollers, in particular to the field of disassembly of roller ring protective caps of pinch rollers, and specifically to a disassembly device for a roller ring protective cap of a pinch roller. Background Art

[0002] On a high-speed wire production line, after the wire is rolled in the finishing mill, it needs to be pinched by the pinch rollers before the laying head can complete the transformation from straight pieces to coils. Danieli's intelligent pinch rollers are located between the finishing mill and the laying head. Their main functions are: ① Vibration reduction: Apply a suitable tension to the rolled piece to prevent any vibration generated downstream of the finishing mill from being transmitted to the finishing mill and causing steel to pile up in the waste box; ② Pinch function: Feed the rolled piece to the laying head at a uniform, stable and appropriate speed to ensure that the rolled piece passes through the laying head smoothly.

[0003] At present, Danieli's pinch roller ring cooling method is water cooling, but water cooling will cause the roller ring to rust, so the water cooling is changed to natural cooling, which solves the problem of difficulty in roller ring removal caused by water cooling corrosion. However, due to the use of natural cooling, during the roller ring removal process, the temperature of the roller ring protection cap can reach 200 to 300 degrees. During removal, the high temperature and the lack of suitable tooling cause the workers to work hard and easily get burned. Utility Model Content

[0004] In order to solve the problem of being easily scalded when removing the high-temperature roller ring protection cap in the prior art, the utility model provides a pinch roller ring protection cap removal device. The driving mechanism in the utility model can remove the high-temperature bolt from the protection cap; at the same time, the clamping mechanism can clamp the protection cap, so that the high-temperature protection cap can be easily removed from the roller ring without direct contact with the human body, thereby preventing the human body from being scalded.

[0005] The technical solution adopted by the device for removing the protective cap of the pinch roller ring of the utility model is:

[0008] In this further technical solution, the protective cap is fixed to the roller ring of the clamping roller by bolts. By rotating the first hand ring in the driving mechanism, the rotating rod and the sleeve can be driven to rotate. The rotating sleeve can unscrew the high-temperature bolt on the protective cap, thereby facilitating the removal of the protective cap from the roller ring. At the same time, the high-temperature protective cap can be clamped by the clamping plate in the clamping mechanism, thereby facilitating the removal of the high-temperature protective cap from the roller ring after the bolt is removed from the protective cap without direct contact with the human body, thereby preventing the human body from being burned.

[0009] Furthermore, the protective cap is provided with a protective cavity, and a through hole communicating with the protective cavity is provided at a position where the bolt is provided on the protective cap, and the bolt passes through the through hole.

[0012] Furthermore, the rotating rod sleeve is provided with a bearing, and the outer ring of the bearing is slidably connected to the inner wall of the cylinder.

[0013] In this further technical solution, the rotating rod can be supported by the provided bearing, thereby facilitating the rotation of the rotating rod.

[0014] Furthermore, a first sliding groove is provided on the inner wall of the cylinder along its length direction, a first sliding block is slidably provided in the first sliding groove, and the first sliding block is connected to the outer ring of the bearing through a second connecting rod.

[0015] In this further technical solution, the first sliding groove and the first sliding block are provided to enable the bearing to move in the cylinder, thereby facilitating the driving mechanism to drive the bolt to rotate while moving toward the outside of the cylinder to unscrew the bolt from the protective cap.

[0016] Furthermore, a vertical plate is arranged at the top of each clamping plate; wherein a bidirectional screw is rotatably arranged in the cylinder, and the bidirectional screw passes through the two vertical plates, and the two vertical plates are respectively located on both sides of the bidirectional screw.

[0017] In this further technical solution, by rotating the bidirectional screw rod, the two vertical plates can be moved closer to or farther away from each other, thereby making the two clamping plates closer to or farther away from each other, so that the two clamping plates clamp the roller ring.

[0018] Furthermore, a second slide groove is provided on the inner wall of the cylinder at a position corresponding to the vertical plate, and a second sliding block matching with the second slide groove is provided on the top of each vertical plate.

[0033] The clamping mechanism 7 in the present utility model can be further referred to in the specific setting. Figure 2 ,according to Figure 2 It can be seen that the clamping mechanism 7 includes a cylinder 8 sleeved on the outside of the sleeve 4 and the rotating rod 5, and two clamping plates 9 for clamping the protective cap 1 are arranged in the cylinder 8; each clamping plate 9 can be further referred to when specifically connecting with the cylinder 8. Figure 2 The top of each clamping plate 9 is fixedly connected to a vertical plate 17, and a first slide groove 14 is opened at the position of the inner top wall of the cylinder 8 corresponding to the vertical plate 17. The first slide groove 14 is opened along the width direction of the cylinder 8, and the top of each vertical plate 17 is fixedly connected to a second slider 20 that matches the second slide groove 19.

[0034] In the present invention, in order to facilitate the movement of the two clamping plates 9, reference Figure 1 and Figure 2It can be seen that a bidirectional screw rod 18 is rotatably connected to the position of the vertical plate 17 in the cylinder 8. The bidirectional screw rod 18 passes through the two vertical plates 17 and is threadedly connected to the two vertical plates 17.

[0036] The working principle of the device for removing the protective cap of the roller ring of the pinch roller is as follows: when the utility model is used, the bolt 2 is first removed from the protective cap 1, and then the roller ring is inserted into the protective cavity 10 so that the protective cap 1 is put on the roller ring, and then the bolt 2 is passed through the through hole 11 and the bolt 2 is allowed to enter the roller ring, so that the protective cap 1 and the roller ring are fixedly connected together by the bolt 2.

[0037] When the roller ring needs to be disassembled after use, the utility model can be brought close to the roller ring until the roller ring and the protective cap 1 are located in the cylinder 8, and then the second hand wheel 21 is rotated to drive the bidirectional screw 18 to rotate. The rotating bidirectional screw 18 makes the two vertical plates 17 and the two clamping plates 9 approach each other until each clamping plate 9 is tightly fitted with the protective cap 1. At this time, the cylinder 8 and the protective cap 1 are fixedly connected together.
