Description

Technical Field

[0001] This utility model relates to a rolling mill guide roll position adjustment device. Background Technology

[0002] Rolling mills are indispensable equipment in the metal processing industry. Guide rolls, as a crucial component of the mill, play a vital role in ensuring the quality and precision of rolled products. The position adjustment of the guide rolls directly affects the stability of the rolling process and product quality; therefore, the design and performance of the guide roll position adjustment device are of paramount importance.

[0003] However, existing mill guide roll position adjustment devices still have some problems. Traditional mill guide roll horizontal position adjustment mainly involves using a lifting cylinder to drive the guide roll bearing seat to run within a lifting track. The horizontal position of the guide roll is then achieved by adjusting the tightness of the bolts and tightening the lock nuts. This adjustment method poses significant safety hazards. Operators need to manually adjust the position around the equipment, which can easily lead to accidental injuries. At the same time, the operation is cumbersome, requires multiple people to cooperate, and is inefficient. More importantly, this method of relying on manual adjustment of bolt tightness makes it difficult to achieve precise position control, which affects the accuracy and consistency of the rolled products.

[0004] Therefore, there is an urgent need for a device that can safely and accurately adjust the position of the rolling mill guide rolls in order to improve rolling efficiency and product quality. Utility Model Content

The two ends of the bracket 3 are fixed on the lifting assembly 300, and the level detector 2 is arranged at the center of the bracket 3. The level detector 2 is electrically connected to the control component 200.

[0017] The specific structure of the mill guide roll 4 position adjustment device in this embodiment is as follows:

[0018] The position adjustment devices for the rolling mill guide roll 4 are symmetrically arranged on both sides of the guide roll 4. Each side includes a balancing component 100, a lifting component 300, and a top lifting component 400. The balancing component 100 includes a load-bearing cylinder 120 and a balancing cylinder 110. The upper end of the load-bearing cylinder 120 is fixed to the rolling mill frame, and the lower end is fixedly connected to the lifting component 300 through a preset rod. The preset rod is a metal connecting rod, one end of which is connected to the piston rod of the load-bearing cylinder 120, and the other end is connected to the upper part of the bearing seat 310 of the lifting component 300. The balance cylinder 110 and the load-bearing cylinder 120 are connected by bolts and connected by oil pipes to form a hydraulic balance system. The balance cylinder 110 includes a cylinder body and a counterweight 1, which is a metal block fixedly connected to the lower part of the cylinder body to balance the weight of the guide roller 4 and reduce the burden on the load-bearing cylinder 120. The lifting assembly 300 includes a bearing seat 310 and a lifting rail 320. The bearing seat 310 is made of metal and its upper part is fixedly connected to the preset rod by multiple bolts. The side is provided with a bearing and is connected to the guide roller. The shaft end of 4 is rotatably connected, allowing the guide roller 4 to rotate freely within the bearing seat 310. The lifting track 320 is fixed on the mill stand and is arranged vertically. The bearing seat 310 and the lifting track 320 are slidably connected, allowing the bearing seat 310 to move vertically along the lifting track 320, thereby adjusting the height position of the guide roller 4. The lifting assembly 400 is arranged below the lifting assembly 300 and includes a lifting rod 440, a rotating component 430, a drive motor 420, and a lifting head 410. The rod 440 is a metal rod-shaped structure with screw threads machined on its surface. The head of the lifting rod 440 is equipped with a lifting head 410, which is a disc-shaped structure that contacts the bottom of the bearing seat 310. The rotating part 430 is a cylindrical structure with a screw nut inside, which is connected to the screw thread on the lifting rod 440. The outer side of the rotating part 430 is connected to the drive shaft of the drive motor 420. The drive motor 420 is fixed on the rolling mill stand and is electrically connected to the control component 200 via a cable.

[0019] Furthermore, the control component 200 includes a controller and an operation panel. The controller has a built-in microprocessor and memory, and is electrically connected to the drive motor 420 via a cable. It is used to control the start, stop, speed and power of the drive motor 420. The operation panel is equipped with buttons and a display screen for human-machine interaction. The level detector 2 is an electronic level, which is arranged at the center of the bracket 3. The bracket 3 is a metal beam structure, with both ends fixed to the lifting components 300 on the left and right sides. The level detector 2 is electrically connected to the control component 200 via a cable, and detects the levelness of the guide roller 4 in real time and transmits the detection signal to the control component 200.

[0020] The working principle of the mill guide roll 4 position adjustment device in this embodiment is as follows:

[0021] When the position of guide roller 4 needs to be adjusted, the drive motor 420 is first started by the control component 200. The drive motor 420 drives the rotating component 430 to rotate. Since the rotating component 430 has a built-in lead screw nut, which is connected to the lead screw thread on the lifting rod 440, the rotational motion of the rotating component 430 is converted into the linear motion of the lifting rod 440, causing the lifting rod 440 to move up and down. The lifting head 410 at the head of the lifting rod 440 contacts the bottom of the bearing seat 310, pushing the bearing seat 310 to move up and down along the lifting track 320, thereby adjusting the height position of guide roller 4. During the adjustment process, the level detector 2 detects the levelness of guide roller 4 in real time and transmits the detection signal to the control component 200. The control component 200 controls the power of the left and right drive motors 420 respectively according to the signal from the level detector 2, so that the guide roller 4 remains in a horizontal state. When the guide roller 4 reaches the preset position, the control component 200 stops the operation of the drive motor 420, completing the adjustment of the position of guide roller 4. The balancing component 100 plays a buffering role during the adjustment of the guide roller 4 position. The load-bearing cylinder 120 bears the weight of the guide roller 4, reducing the burden on the lifting component 400. The balancing cylinder 110 is connected to the load-bearing cylinder 120 to form a hydraulic balancing system. The balancing counterweight 1 at the bottom of the balancing cylinder 110 provides additional balancing force, reducing the burden on the load-bearing cylinder 120 and making the adjustment of the guide roller 4 position more stable and reliable.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
