Description

Technical Field

[0001] The utility model belongs to the technical field of continuous casting equipment, and further belongs to the technical field of hot delivery billet separation device, and specifically relates to a billet separation device with simple structure, easy operation, reliable operation, and the ability to effectively improve the accuracy and efficiency of continuous casting billet separation. Background Art

[0002] In the continuous casting production process, the hot delivery methods of the billet continuous casting machine are generally divided into single-piece hot delivery and multiple-piece hot delivery. An excellent hot delivery process route plays a vital role in energy saving and consumption reduction. Since most steel mills are affected by the process layout of the continuous casting and steel rolling processes, in the continuous casting process, most process designs for the billets from the billet discharge roller to the hot delivery roller adopt the method of pushing multiple billets together to the hot delivery roller position, and then using the steel turning machine to deliver the billets one by one to the hot delivery roller, and then send them to the steel rolling process for rolling through the hot delivery roller. At present, the hot delivery billet separation methods used by various steel mills are mainly divided into two categories: "push steel machine + steel turning machine structure" and "step-by-step billet separation structure", but the above two billet separation methods have the following shortcomings:

[0003] The main advantage of the "steel pusher + steel turning machine structure" is that the billets are accurately separated and not easily carried; but the disadvantages are that the equipment structure is complex, the running time of a single billet from the stop position to the hot delivery roller is long, there are many operating steps, the billet turning operation efficiency is low, and the hot delivery efficiency is seriously affected.

[0004] The main advantages of the "step-by-step billet separation structure" are short billet separation time and simple equipment structure; but the main disadvantage is that its oil cylinder is controlled by a position sensor, the control system is relatively complex, and the investment is high. Secondly, billet stripping often occurs during the billet separation process (that is, the second billet will be pushed onto the roller conveyor along with the first billet). At this time, the operator needs to manually separate the two billets before continuing production. Each manual billet separation takes more than ten minutes, and an average of 3 to 5 manual processes are required every day, which is time-consuming and labor-intensive, affecting the heat delivery efficiency and increasing the company's production costs.

[0005] Therefore, the key to solving this problem is to research and develop a billet separation device with simple structure, easy operation, reliable operation, and the ability to effectively improve the accuracy and efficiency of continuous casting billet separation. Utility Model Content

[0006] The purpose of the utility model is to provide a billet separation device which has a simple structure, is easy to operate, works reliably, and can effectively improve the accuracy and efficiency of continuous casting billet separation.

[0007] The purpose of the present utility model is achieved in this way, including an inclined sliding track device, a steel turning machine, and an arc-shaped slide rail, wherein a plurality of inclined sliding track devices are arranged at the front end of the steel turning machine; a plurality of arc-shaped slide rails are arranged above the steel turning machine; the angle between the slide rail of the inclined sliding track device and the ground is an acute angle; the steel turning machine adopts a movable swing arm structure to turn the ingot; the movable claw of the steel turning machine cooperates with the inclined slide rail of the inclined sliding track device; the working surface length of the movable claw of the steel turning machine is smaller than the width of the ingot; the angle between the working surface of the movable claw of the steel turning machine and the arc-shaped slide rail is an obtuse angle; the upper end face of the arc-shaped slide rail is flush with the upper surface of the roller of the hot delivery roller.

[0008] The utility model is composed of an inclined sliding track device, a steel turning machine, and an arc-shaped slide rail; the included angle between the slide rail of the inclined sliding track device and the ground is 26.3 degrees, which ensures that the billet can smoothly slide to the bottom of the slide rail on the inclined slide rail, and the billet will not slide down and turn over due to being too large or too small, or it will not be difficult to slide down due to excessive friction; the working surface length of the movable claw of the steel turning machine is 10mm smaller than the width of the billet, so that the claw can accurately lift and turn the first billet during the billet turning process, realize the billet separation function, and greatly improve the billet separation accuracy; the included angle between the working surface of the movable claw of the steel turning machine and the arc-shaped slide rail is 98 degrees, so that the turning force condition of the claw and the friction condition between the billet and the slide rail can achieve the optimal effect.

[0009] During operation, when the billet is pushed to the slope position of the inclined slide rail device, the billet will automatically slide to the bottom of the slope along the inclined slide rail. At this time, the steel turning machine detects the arrival of the billet, and the movable claw of the steel turning machine automatically lifts up to push the first billet along the arc slide rail to the hot delivery roller position. When the hot delivery roller detects the arrival of the billet, the hot delivery roller automatically starts and sends the billet out along the hot delivery line. At the same time, the steel turning machine returns to its original position to perform the second billet turning operation. During the operation of the steel turning machine, since the movable claw is designed as a movable swing arm structure instead of a traditional claw cross arm, after the movable claw transports the first billet away, the second billet on the inclined slide rail will automatically slide down without the need for a traditional steel pusher to push it. During the process of the movable claw returning to its original position, the movable swing arm can automatically rotate when it touches the billet without interfering with the billet, and continue to return to its original position. After reaching the original position, the movable claw can automatically rotate to the billet turning state by its own weight. Each time the billet is turned, the first billet can be accurately turned to the hot delivery roller, avoiding the billet stripping situation. The operation time of the entire mechanism is about 5 to 10 seconds, and its billet separation speed is much higher than the conveying speed of the hot delivery roller. The entire process is automatically controlled, without the need for manual operation, and the operation efficiency is high.

[0010] The utility model has the advantages of fewer operation steps, accurate blank separation, high blank separation operation efficiency and low labor intensity for workers.

[0011] The utility model has the advantages of simple structure, easy operation and reliable operation, and can effectively improve the accuracy and efficiency of continuous casting billet separation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 5 As shown, the utility model includes an inclined sliding track device 1, a steel turning machine 2, and an arc-shaped slide rail 3. Several inclined sliding track devices 1 are arranged at the front end of the steel turning machine 2; several arc-shaped slide rails 3 are arranged above the steel turning machine 2; the angle between the slide rail of the inclined sliding track device 1 and the ground is an acute angle; the steel turning machine 2 adopts a movable swing arm structure to flip the ingot 5; the movable claw of the steel turning machine 2 cooperates with the inclined slide rail of the inclined sliding track device 1; the working surface length of the movable claw of the steel turning machine 2 is smaller than the width of the ingot 5; the angle between the working surface of the movable claw of the steel turning machine 2 and the arc-shaped slide rail 3 is an obtuse angle; the upper end face of the arc-shaped slide rail 3 is flush with the upper surface of the roller of the hot delivery roller 4.

[0020] The included angle between the slide rail of the inclined slide track device 1 and the ground is 26.3°.

[0021] The slide rails of the inclined slide rail device 1 need to be heat treated to improve wear resistance.

[0022] The working surface length of the movable claw of the steel turning machine 2 is 10 mm smaller than the width of the casting billet 5.

[0023] The angle between the working surface of the movable claw of the steel turning machine 2 and the arc-shaped slide rail 3 is 98°.

[0024] The arc-shaped slide rail 3 is in an arc shape.

[0025] The arc-shaped slide rail 3 needs to be heat-treated to improve its wear resistance.

[0026] The steel turning machine 2 includes a long axis assembly 21, a push head device 22, a hydraulic cylinder 23, a support 24, a pin shaft 25, a pusher claw device 26, and a bearing seat assembly 27; a total of two pusher head devices 22 are arranged on the axis of the long axis assembly 21; one support 24 is arranged on each side of the long axis assembly 21 corresponding to the position of the push head device 22; a hydraulic cylinder 23 is arranged between the push head device 22 and the support 24; the push head device 22 and the hydraulic cylinder 23 are connected by a pin shaft 25; the hydraulic cylinder 23 and the support 24 are connected by a pin shaft 25; several pusher claw devices 26 are arranged on the axis of the other side of the long axis assembly 21; several bearing seat assemblies 27 are arranged on the axis of the long axis assembly 21.

[0027] The long axis of the long axis assembly 21 can be manufactured in sections, and the sections are connected by couplings.

[0028] The pusher claw of the pusher claw device 26 is a movable swing arm structure.

[0029] The working principle and working process of this utility model:

[0030] The utility model is composed of an inclined sliding track device 1, a steel turning machine 2, and a curved slide rail 2; the angle between the slide rail of the inclined sliding track device 1 and the ground is 26.3°, which ensures that the ingot 5 can slide smoothly to the bottom of the slide rail on the inclined slide rail, and the ingot 5 will not slide down and turn over due to being blocked by the slope being too large or too small, or it will not be difficult to slide down due to excessive friction; the working surface length of the movable claw of the steel turning machine 2 is 10mm smaller than the width of the ingot 5, so that the claw can accurately lift and turn the first ingot 5 during the ingot turning process, realize the ingot separation function, and greatly improve the accuracy of ingot separation; the working surface of the movable claw of the steel turning machine 2 and the curved slide rail 3 are 98°, so that the flipping force of the claw and the friction between the ingot 5 and the slide rail can achieve the optimal effect.

[0031] During operation, when the billet 5 is pushed to the slope position of the inclined slide track device 1, the billet 5 will automatically slide to the bottom of the slope along the inclined slide rail. At this time, the steel turning machine 2 detects the arrival of the billet 5, and the movable claw of the steel turning machine 5 automatically lifts up to push the first billet 5 along the arc-shaped slide rail 3 to the position of the hot delivery roller 4. When the hot delivery roller 4 detects the arrival of the billet 5, the hot delivery roller 4 automatically starts and sends the billet 5 along the hot delivery line. At the same time, the steel turning machine 2 returns to its original position to perform the second billet turning operation. During the operation of the steel turning machine 2, since the movable claw is designed as a movable swing arm structure instead of a traditional claw cross arm, after the movable claw transports the first billet 5 away, the second billet 5 on the inclined slide rail will automatically slide down without the need for a traditional steel pusher to push it. During the process of the movable claw returning to its original position, the movable swing arm can automatically rotate when it contacts the billet 5 without interfering with the billet 5, and continue to return to its original position. After reaching the original position, the movable claw can automatically rotate to the billet turning state by its own weight. Each time the billet is turned, the first billet 5 can be accurately turned over to the hot delivery roller 4, avoiding the billet stripping situation. The operation time of the entire mechanism is about 5 to 10 seconds. Its billet separation speed is much higher than the conveying speed of the hot delivery roller 4, and the entire process is automatically controlled without the need for manual operation.
