Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting equipment, in particular to a continuous casting billet baffle device, which is used for effectively blocking the billet during the process of conveying the billet by a continuous casting machine. Background Art

[0002] As people's demand for steel is increasing, improving the operating efficiency of the billet production line has become a top priority. In the continuous casting production process, accidents such as billet collision or detachment from the rollers often occur due to the unsmooth back-end reversing work, resulting in production shutdowns, which not only reduces production efficiency but also causes unnecessary losses. Therefore, stable billet transportation is the key to maximizing the efficiency of the continuous casting machine. The billet baffle device can effectively adjust the production rhythm according to the back-end transportation situation. The traditional billet baffle device often has problems such as inaccurate positioning, scratching the billet or causing the billet to fall off the roller, which affects the operating efficiency of the production line and the quality of the continuous casting billet, and also creates unsafe factors.

[0003] Therefore, designing a billet baffle device that can automatically and accurately position is of great significance for improving the automation level and production efficiency of the continuous casting production line. Utility Model Content

[0023] The present invention is further described below by using examples in combination with the use process. Example 1

[0024] A continuous casting billet baffle device is mainly used in the process of conveying billets in a continuous casting machine, and can realize accurate positioning and effective blocking of the billets. The device comprises a frame 1, a connecting rod 2, a connecting rod shaft 3, a baffle 4, a hydraulic cylinder 5, an axis end baffle 6, a bracket 7, a base 8, a buffer device 9, a crank 10, a proximity switch 11, a sensor bar 12, a buckle device 13, a crossbeam 14, a conveying roller 15, a bearing seat 16, and a continuous casting billet 17. The baffle 4 is connected to the connecting rod 2 through the connecting rod shaft 3, and the two ends of the connecting rod shaft 3 are respectively hinged with the output ends of the two groups of hydraulic cylinders 5. The other ends of the two groups of hydraulic cylinders 5 are connected to the bracket 7 fixed on the base 8 through a pin shaft, so that the baffle 4 and the connecting rod shaft 3 can be displaced with the reciprocating extension and contraction of the hydraulic cylinder 5; the other end of the connecting rod 2 is connected to the frame 1 through a pin shaft. In order to ensure the stability and firmness of the overall frame 1, the frame 1 is welded and fixed to the crossbeams 14 on both sides of the conveying roller 15 installed on the bearing seat 16; in order to prevent the baffle 4 from falling back due to gravity factors In order to prevent damage to the hydraulic cylinder 5 and other devices during the process, two groups of buffer devices 9 are provided, one end of the buffer device 9 is connected to the crank 10 welded to the lower part of the frame 1, and the other end is connected to the bottom of the baffle 4 through a pin shaft, and a shaft end baffle 6 is provided at the connection; in order to accurately and automatically position the rise and fall of the baffle 4, two groups of proximity switches 11 are respectively fixed to the upper and lower parts of the crossbeam 14 through slats, and the induction strip 12 matched with the proximity switch 11 is fixed to the connecting rod shaft 3 through a buckle device 13, and the position can change with the movement of the connecting rod shaft 3. Among them, the buckle device can use a half clamp structure, including two semicircular rings, buckled on the connecting rod shaft and fixed to the connecting rod shaft by bolt locking, and the induction strip is set on the buckle device by welding or other methods.

[0025] When the production rhythm at the rear end is not smooth or there is a situation of slab stagnation, it is necessary to adjust the conveying rhythm of the cast billet during the conveying process. When the continuous casting billet 17 runs to the front of the continuous casting billet baffle 4 device, the hydraulic cylinder 5 is controlled to start, and the connecting rod shaft 3 and the baffle 4 rise as the hydraulic rod is extended. The connecting rod 2 drives the baffle 4 to move forward in the direction of the continuous casting billet with one end of the frame 1 as a fulcrum, and the sensing bar 12 also moves upward with the connecting rod shaft 3. When the sensing bar 12 is within the sensing range of the proximity switch 11 fixed on the upper part of the crossbeam 14, the hydraulic cylinder 5 stops working, the baffle 4 is in a raised state and is about 400mm higher than the upper surface of the conveying roller 15. At the same time, the proximity roller stops running, which can stop the continuous casting billet 17 being conveyed to prevent it from being conveyed to the blocking area at the rear end.

[0026] When the production rhythm at the rear end has been adjusted smoothly, the hydraulic cylinder 5 is started, the connecting rod shaft 3 and the baffle 4 descend as the hydraulic rod retracts, and the sensing bar 12 also moves downward. The connecting rod 2 drives the baffle 4 to move backward in the direction of the continuous casting billet 17, and the continuous casting billet baffle 4 moves downward. When the sensing bar 12 is within the sensing range of the proximity switch 11 fixed at the lower part of the crossbeam 14, the hydraulic cylinder 5 stops working, the baffle 4 is in the initial state, and the top of the baffle 4 is about 50 mm lower than the upper surface of the conveying roller 15. The roller starts the continuous casting billet 17 to continue to convey stably.

[0027] In order to prevent the hydraulic cylinder 5 and related components from being damaged due to impact of the casting billet or inertia of the baffle 4 during operation, two groups of buffer devices 9 (the buffer devices can be hydraulic buffers or spring buffers, etc.) are provided between the crank 10 and the baffle 4. The buffer devices 9 have a certain amount of expansion and contraction, which can not only ensure the smooth lifting and lowering of the baffle, but also prevent the hydraulic cylinder 5 and other components from being damaged by impact.

[0028] The utility model structure can not only realize the lifting and lowering of the billet baffle device controlled by the hydraulic cylinder, but also realize the automatic and accurate positioning of the baffle device through the proximity switch and the induction strip, thereby avoiding the problems of the traditional billet baffle device causing scratches on the billet due to inaccurate positioning, the billet directly falling off the roller or the billet colliding with each other, and so on, which not only stabilizes the production rhythm, improves the transportation efficiency of the billet, but also ensures the quality of the continuous casting billet. In addition, the utility model structure also effectively avoids the damage of the hydraulic cylinder caused by the fall-back impact through the buffer device, which not only avoids certain losses, but also reduces unnecessary manual maintenance workload and improves work efficiency.
