Technical Field

[0001] This utility model relates to the field of rolling mill feeding technology, specifically a scratch-resistant rolling mill pipe chuck. Background Technology

[0002] Chucks are used to hold steel pipes and feed them accurately into the rolling mill. Traditional chucks are prone to scratching the surface of steel pipes due to direct friction between the chuck and the pipe surface or unreasonable chuck structure. This not only affects the appearance quality of the product, but may also reduce the product's performance and increase production costs. Furthermore, the position of the existing chuck body is fixed and cannot be adjusted in terms of front and back position and angle, thus lacking flexibility. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a scratch-resistant rolling mill inlet chuck with advantages such as adjustable position, thus solving the problems mentioned in the background art.

The upper and lower ends of the chuck body are provided with notches in the middle. Two clamping plates are installed at the front of the upper end of the notches. Two locking bolts are provided on the left side wall of each clamping plate. The locking bolts pass through the two clamping plates and connect to the right side. Electric hydraulic cylinders are installed on the front of both side walls of the chuck body. The inner end of each electric hydraulic cylinder passes through the chuck body and is equipped with a clamping plate.

[0005] As a further improvement of this utility model: the clamping plate is made of silicone material, and anti-slip particles are provided on the surface of the clamping plate. The anti-slip particles increase the friction between the clamping plate and the surface of the steel pipe, thereby improving the anti-slip performance.

[0006] As a further embodiment of this utility model: a telescopic plate is slidably installed at the front end of the push box, a slide rail is provided at the middle of the upper end of the push box, a slider is installed at the upper end of the telescopic plate, the slider is slidably connected in the slide rail, connecting blocks are installed on both sides of the rear end of the slider, and a push plate is installed at the rear end of the connecting blocks. By pushing the push plate, the push plate drives the two connecting blocks to move forward, drives the slider to move forward, drives the telescopic plate to move forward, and drives the front and rear position of the clamp body to move.

[0007] As a further improvement of this utility model: limit grooves are provided on both sides of the slide, and limit blocks are installed on the lower part of both sides of the slider. The lower ends of the limit blocks are slidably connected in the limit grooves, and the limit blocks slide in the limit grooves to achieve the limit.

[0008] As a further improvement of this utility model: a connecting plate is installed at the front end of the telescopic plate, and a motor box is installed at the front end of the connecting plate. A double-headed motor is installed inside the motor box. The motor shafts at both ends of the double-headed motor pass through the motor box and are equipped with arc-shaped seats. The lower ends of the arc-shaped seats are fixedly connected to the fixed seats. When the double-headed motor is started, the double-headed motor drives the arc-shaped seats to rotate through the motor shafts, thereby adjusting the angle of the clamp body and realizing installation at different angles, which is flexible.

[0009] As a further improvement of this utility model, the inner sidewalls of the clamps are provided with sealing sheets, which are made of silicone material, thereby improving the tightness between the sealing sheets.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, tightening several locking bolts fixes the clamping plate. Activating the electric hydraulic cylinder causes the two clamping plates to move inward, squeezing and fixing both sides of the steel pipe. The anti-slip particles increase the friction between the clamping plate and the surface of the steel pipe, improving anti-slip properties and preventing direct friction between the clamping head and the surface of the steel pipe, thus avoiding scratches on the steel pipe surface and not affecting the product's appearance quality.

[0011] 2. In this utility model, pushing the push plate causes the two connecting blocks to move forward, which in turn causes the slider to move forward, the telescopic plate to move forward, and the movement of the chuck body in the front and back positions to start the dual-head motor.

Two locking bolts 4 are provided on the left side wall of each clamping plate 6. The locking bolts 4 pass through the two clamping plates 6 and connect to the right side. Electric hydraulic cylinders 5 are installed on the front of both sides of the chuck body 7. The inner end of each electric hydraulic cylinder 5 passes through the chuck body 7 and is equipped with a clamping plate 2.

[0017] The clamping plate 2 is made of silicone material, and its surface is covered with anti-slip particles. These particles increase the friction between the clamping plate 2 and the steel pipe surface, improving its anti-slip properties. A telescopic plate 11 is slidably installed at the front end of the push box 13. A slide rail 12 is located in the middle of the upper end of the push box 13. A slider 18 is installed on the upper end of the telescopic plate 11 and slides within the slide rail 12. Connecting blocks 8 are installed on both sides of the rear end of the slider 18, and a push plate is installed at the rear end of the connecting blocks 8. By pushing the push plate, the push plate drives the two connecting blocks 8 to move forward, which in turn drives the slider 18 to move forward, drives the telescopic plate 11 to move forward, and moves the clamping body 7 back and forth. Limit grooves 17 are provided on both sides of the slide rail 12, and limit grooves 17 are installed on the lower part of both sides of the slider 18. The lower ends of the positioning block 16 and the limiting block 16 are slidably connected within the limiting groove 17, and the limiting block 16 slides within the limiting groove 17 to achieve limiting.
