Description

Technical Field

[0002] The stripping device is an indispensable part of the continuous casting production line. Its design and performance directly affect the operating efficiency of the continuous casting machine and the quality of the cast billet. Through continuous optimization and improvement of the stripping device, the automation level of continuous casting production can be improved, the production cost can be reduced, the quality and production efficiency of the cast billet can be improved, and the billet can be transferred to the subsequent conveying equipment for cooling and further processing. The continuous casting machine dummy rod pulls the continuous casting billet through the straightening machine for a distance, and then the continuous casting billet is separated from the dummy head through this device.

[0003] In view of the current continuous casting machine field, corresponding solutions have been formulated for the following existing problems:

[0004] At present, when the continuous casting machine stripping device is in use, the dummy rod is usually directly responsible for the pulling of the continuous casting billet. During the pulling process, the dummy rod body is mainly guided and directed by the original production equipment. The recovery device usually used to recover the dummy rod is at a certain distance from the production equipment. Due to the nature of the dummy rod working over a long distance, the dummy rod will have a slight position deviation during the long-distance movement, resulting in the dummy rod being unable to enter the recovery device with a better posture. After a long time, it is easy to cause the error between the dummy rod and the recovery device to increase, causing an imbalance. In addition, the moving posture of the dummy rod will also affect the posture of the billet in the subsequent movement process. Therefore, the movement accuracy of the dummy rod is very important.

[0024] The lateral guide mechanism 3 includes a driving hydraulic cylinder 31, a fixed block 32, a limiting wheel 33, and a limiting detection structure 34. The driving hydraulic cylinder 31 is installed on one side of the fixed base plate 1, and the fixed block 32 is installed on the output end of the driving hydraulic cylinder 31.

At the other end, when the auxiliary wheel 345 contacts the side of the ingot rod, it will push the swing arm 344 to move outward, and the swing amplitude of the swing arm 344 and the position of the swing arm 344 will continue to change. The swing amount will be fed back to the detection motor 343 by the swing arm 344, and then the detection motor 344 will analyze and calculate the swing amount of the swing arm 344 through the external control system, so as to calculate the offset of the ingot rod, and control the lateral guide mechanism through the external control system, so that the driving hydraulic cylinder in the lateral guide mechanism changes the working position of the fixed block according to the swing amount, thereby realizing the dynamic guide rod correction and limiting work.

[0027] Preferably, the limiting frame 2 includes a support plate 21 and a support roller 22, a number of the support plates 21 are installed on both sides of the fixed base plate 1, a number of the support rollers 22 are hingedly installed on the inner side of the support plate 21, and a number of the support rollers 22 are distributed at the upper and lower ends of the support plate 21, leaving a space in the middle for the guide rod to penetrate and slide.

[0029] The working principle of the ingot stripping device of the utility model for continuous casting machine:

[0030] When the stripping device of the continuous casting machine is in use, the dummy rod enters into the limit frame installed on the fixed bottom plate, and the limit frame performs vertical limit and guide work on the dummy rod. Then the dummy rod enters into the working area of ​​the lateral guide mechanism under the traction of the external traction device, and the external control system performs lateral limit work on the dummy rod in the lateral guide mechanism.

[0031] The limit frame can guide and slide the dummy bar through the support rollers distributed above and below, and control the moving trajectory of the dummy bar through the limit frame. When the dummy bar enters the working area of ​​the lateral guide mechanism, the limit detection structures on both sides of the lateral guide mechanism will detect the moving state of the dummy bar, and the deviation degree of the dummy bar will be fed back to the external control system through the limit detection structure.

[0032] Then, the working state of the driving hydraulic cylinder is controlled by the external control system, and the driving hydraulic cylinder can adjust the working position of the limiting wheel, so that the limiting wheels distributed on both sides can put the dummy rod in a better moving position through the clamping state;

[0033] The driving hydraulic cylinder can be adaptively adjusted according to the width of the dummy rod to meet the movement requirements of dummy rods of different specifications. The lateral guide mechanism is equipped with a limit detection structure to correct the deviation of the dummy rod in time. The limit detection structure and the driving hydraulic cylinder are dynamically linked and coordinated.

[0034] The dummy bar can be pressed down and limited by the pressing limit mechanism during the movement. The driving motor drives the pressing roller to swing and press down through the connecting rod to prevent the dummy bar from tilting and bouncing during the movement, and avoid the dummy bar itself from large displacement.

[0035] The working position of the limiting wheel can be adjusted through the installation notch provided in the fixed block. The limiting wheels of different specifications can be replaced according to the use requirements, or the working stroke of the driving hydraulic cylinder can be changed through the installation position of the limiting wheel;

[0036] When the working stage of the ingot guide rod is completed, the driving hydraulic cylinder will drive the limiting wheel to move outward to make room for the billet to move. At this time, the downward pressure limiting mechanism () can switch the downward pressure through the driving motor, and can flexibly adjust the downward pressure requirements of the ingot guide rod and the billet in a targeted manner, and can control the working status of the lateral guiding mechanism and the downward pressure limiting mechanism according to usage requirements.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
