Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ingot clamping equipment, and particularly to a clamping tooling for casting multiple ingots in a row and its usage method. Background Art
[0002] Ingot casting is a process in the iron and steel production process of pouring molten steel into a mold and forming an ingot with a certain shape and size after cooling. In the ingot casting production workshop, in order to increase the ingot casting output in a limited site, many enterprises will adopt the form of casting multiple ingots together to increase the output. Among them, casting multiple ingots in a row is one of them. The clamping tooling is an important equipment to ensure the safety, stability and efficiency of the ingot during production, handling and subsequent processing.
[0003] Among them, after the ingot is cast and formed, the ingot is often first pushed out of the mold, and then the ingot is clamped. However, after the ingot is pushed out of the mold, the ingot may tilt, which easily leads to uneven contact between the fixture and the ingot, resulting in unstable clamping. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides a clamping tooling for casting multiple ingots in a row, including a cross beam. A lifting arm is fixedly connected to the top of the cross beam. Hydraulic cylinders are fixedly connected to both the left and right sides of the cross beam. Fixed plates are fixedly connected to one side of the two hydraulic cylinders close to the cross beam. Ten clamping blocks are slidably connected to the bottom of the cross beam. The ten clamping blocks are divided into two groups of five. The side walls of the two fixed plates are fixedly connected to the side walls of the two groups of clamping blocks. The parts included in the ten clamping blocks are the same.
[0005] A leveling mechanism, which includes connecting rods I fixedly connected to the front and back of the clamping blocks. Rollers are rotatably connected to the inner walls of the two connecting rods I. Inclined plane pushing blocks are arranged on the front and back of the clamping blocks. Connecting plates are arranged on the front and back of the cross beam. The tops of the two connecting plates are fixedly connected to the bottom of the cross beam. Spring return rods I are fixedly connected to the tops of the two inclined plane pushing blocks. The outer walls of the two spring return rods I are slidably connected to the inner walls of the two connecting plates.
[0006] A grasping mechanism, which includes a pressing block slidably connected to the inner wall of the clamping block. A spring return rod II is fixedly connected to the side wall of the pressing block. The outer wall of the spring return rod II is slidably connected to the inner wall of the clamping block.
[0007] The grasping mechanism further includes a fixed frame I fixedly connected to the side wall of the clamping block. A rotating frame is rotatably connected to the inner wall of the fixed frame I. The inner wall of the rotating frame is slidably connected to the side wall of the spring return rod II. A sliding block is slidably connected to the inner wall of the clamping block.
[0008] Among them, the side wall of the sliding block is slidably connected to the inner wall of the rotating frame. A spring block is slidably connected to the inner wall of the sliding block. A knocking component is arranged on the inner wall of the clamping block, and a pushing component is arranged on the inner wall of the extrusion block. The entire crossbeam is lifted by hanging the hook of the crane on the lifting arm. After the ingot is cast and pushed out of the casting mold, the crossbeam is hoisted above the ingot. Then, the hydraulic cylinder is started to extend to push the two fixed plates closer to the crossbeam, driving the clamping block to move, causing the connecting rod one to move, and making the roller contact the inclined surface of the inclined surface pushing block. During the continuous movement of the roller, it will squeeze the inclined surface of the inclined surface pushing block, causing the two inclined surface pushing blocks to approach each other, driving the spring return rod one to move, and allowing the spring return rod one to accumulate resilience. When the inclined surface pushing block moves and contacts the inclined ingot, it will push the ingot to move until the side wall of the ingot is parallel to the side wall of the clamping block. After the ingot is vertical, the roller will separate from the inclined surface of the inclined surface pushing block, making the inclined surface pushing block stationary. At the same time, when the clamping block moves, it will also drive the extrusion block to move, causing the extrusion block to contact the ingot. At this time, when the clamping block continues to move, the extrusion block will be squeezed and retract into the clamping block, driving the spring return rod two to move, allowing the spring return rod two to accumulate resilience. When the spring return rod two moves, it will push the rotating frame to rotate, causing the rotating frame to push the sliding block to extend out of the clamping block, making the sliding block move to the bottom of the ingot, driving the spring block to move until the spring block separates from the extrusion block. At this time, since the spring block was in a compressed state before, the resilience of the spring block will be released, causing the spring block to contact the bottom of the ingot and support the bottom of the ingot until the ingot contacts the clamping block and is clamped. By making the ingot parallel to the clamping block before clamping the ingot, it effectively prevents the ingot from tilting, resulting in a smaller contact area between the extrusion block and the ingot and affecting the clamping stability. At the same time, through the cooperation of the inclined surface pushing block with the clamping block and the spring block, the conventional clamping of the ingot is changed to grasping, increasing the stability of the ingot during hoisting.
[0009] Preferably, the knocking component includes a fixed frame fixedly connected to the inner wall of the clamping block. A sliding plate is slidably connected to the inner wall of the fixed frame. A connecting rod one is rotatably connected to the bottom of the sliding plate. The inner wall of the connecting rod one is rotatably connected to the side wall of the inclined surface pushing block located at the back. Two concave-convex plates are arranged on the side wall of the clamping block, and the tops of the two concave-convex plates are fixedly connected to the bottom of the crossbeam.
[0010] Wherein, two fixing brackets II are fixedly connected to the side of the clamping block away from the fixing bracket I. Spring arc-shaped blocks are rotatably connected to the inner walls of the two fixing brackets II. L-shaped rods are fixedly connected to the side walls of the two spring arc-shaped blocks. The side walls of the two L-shaped rods are slidably connected to the side wall of the concave-convex plate. During the process of the clamping block clamping the ingot, it will drive the fixing bracket II to move, causing the spring arc-shaped block to move, enabling the L-shaped rod to slide on the side wall of the concave-convex plate. When the L-shaped rod moves from the concave position to the convex position of the concave-convex plate, the L-shaped rod will be squeezed. The L-shaped rod will push the spring arc-shaped block to rotate, allowing the spring arc-shaped block to accumulate resilience. As the clamping block continues to move, the L-shaped rod will come into contact with the concave position of the concave-convex plate again, and the resilience of the spring arc-shaped block will be released, driving the spring arc-shaped block to quickly return to its original position. At this time, during the return process of the spring arc-shaped block, it will contact the joint surface between the ingot and the extrusion block, strike the ingot, and cause the oxide layer generated after the ingot casting to crack.
[0011] Preferably, the knocking component further includes a blocking block fixedly connected to the top of the sliding plate. An air inlet groove is formed in the top of the fixed frame. The outer wall of the blocking block is slidably connected to the inner wall of the air inlet groove. A gas transmission pipe is connected through the side wall of the fixed frame. Two shunt pipes are connected through the outer wall of the gas transmission pipe;
[0012] Wherein, a jet plate is fixedly connected to the side of the clamping block away from the fixing bracket I. The top of the jet plate is connected through the bottom of the gas transmission pipe. The top of the jet plate is connected through the bottoms of the two shunt pipes. At the same time, when the roller pushes the inclined plane push block to move, the inclined plane push block located at the back will also drive the connecting rod I to rotate, causing the connecting rod I to push the sliding plate to rise, driving the blocking block to rise. When the blocking block enters the air inlet groove, it will block the air inlet groove. At this time, the inside of the fixed frame is in a sealed state, and the sliding plate will squeeze the gas inside the fixed frame. At this time, the squeezed gas will be blocked by the blocking block. Therefore, the gas will generate high pressure.
[0013] Preferably, the pushing component includes a placement groove formed in the inner wall of the extrusion block. An oil storage pipe is fixedly connected to the inner wall of the fixed frame. A piston rod I is slidably connected to the inner wall of the oil storage pipe. A piston rod II is slidably connected to the inner wall of the oil storage pipe. Hydraulic oil is provided in the inner wall of the oil storage pipe;
[0014] Wherein, the bottom of the piston rod I is fixedly connected to the top of the sliding plate. The bottom of the piston rod II is fixedly connected to a pushing plate. Two extrusion plates are slidably connected to the inner wall of the placement groove. When the sliding plate rises, it will drive the piston rod I to rise, causing the piston rod I to squeeze the hydraulic oil in the oil storage pipe. The squeezed hydraulic oil will push the piston rod II to descend, thereby causing the piston rod II to push the pushing plate to descend.
[0015] Preferably, the pushing assembly further includes a pressure-receiving rod fixedly connected to the top of the top pressing plate. A rotating plate is rotatably connected to the inner wall of the placement groove. Two second connecting rods are rotatably connected to the inner wall of the rotating plate. The inner walls of the two second connecting rods are rotatably connected to one side of the two pressing plates close to the rotating plate;
[0016] Among them, two spring return rods III are fixedly connected to the inner wall of the placement groove. The outer walls of the two spring return rods III are slidably connected to the inner walls of the two pressing plates. A number of pushing rods are slidably connected to the inner wall of the extrusion block. The pushing plate will push the pressure-receiving rod downward, causing the top pressing plate to descend, making the second connecting rod at the top rotate, thereby driving the rotating plate to rotate, causing the rotating plate to tilt, driving the second connecting rod at the bottom to rotate, and thus causing the bottom pressing plate to rise, bringing the two pressing plates closer to each other.
[0017] Preferably, the pushing assembly further includes a third connecting rod fixedly connected to the top of the pushing plate. A push rod is fixedly connected to the bottom of the third connecting rod. A spherical rod is rotatably connected to the inner wall of the air delivery pipe. An arc-shaped spring is fixedly connected to the bottom of the spherical rod. The side of the arc-shaped spring away from the spherical rod is fixedly connected to the outer wall of the air delivery pipe. When the pushing plate descends, it will also drive the third connecting rod to descend, thereby causing the push rod to descend. As the push rod continues to descend, the push rod will contact the spherical rod. The push rod will squeeze the spherical rod, causing the spherical rod to rotate, making the side of the spherical rod in contact with the push rod descend and the other side of the spherical rod rise.
[0018] A method for using a clamping tool for casting multiple steel ingots in a row includes the following steps:
[0019] S1: Equipment installation: The entire crossbeam is lifted by hanging the hook of the crane on the lifting arm;
[0020] S2: Steel ingot correction: The crossbeam is hoisted above the steel ingot, and then the hydraulic cylinder is started to extend to drive the clamping block to move, so that the roller contacts the inclined surface of the inclined surface pushing block, squeezing the inclined surface of the inclined surface pushing block, making the two inclined surface pushing blocks approach each other. When the inclined surface pushing block moves and contacts the inclined steel ingot during the movement, it will push the steel ingot to move until the side wall of the steel ingot is parallel to the side wall of the clamping block;
[0021] S3: Steel ingot clamping: After the steel ingot is corrected, the clamping block continues to move and contacts the steel ingot to clamp the steel ingot.
[0022] The present invention has the following beneficial effects:
[0023] When the present invention is in use, the entire crossbeam is lifted by hanging it on the lifting arm of a crane with a hook. After the ingot is cast and pushed out of the casting mold, the crossbeam is hoisted above the ingot. Then, the hydraulic cylinder is activated to extend, pushing two fixed plates closer to the crossbeam, driving the clamping blocks to move, causing the first connecting rod to move, and making the rollers contact the inclined surfaces of the inclined surface pushing blocks. During the continuous movement of the rollers, the inclined surfaces of the inclined surface pushing blocks will be squeezed, causing the two inclined surface pushing blocks to approach each other, driving the first spring return rod to move, and allowing the first spring return rod to accumulate resilience. When the inclined surface pushing blocks contact the inclined ingot during movement, they will push the ingot to move until the side wall of the ingot is parallel to the side wall of the clamping block. After the ingot is vertical, the rollers will separate from the inclined surfaces of the inclined surface pushing blocks, keeping the inclined surface pushing blocks stationary. At the same time, when the clamping blocks move, they will also drive the extrusion blocks to move, causing the extrusion blocks to contact the ingot. At this time, as the clamping blocks continue to move, the extrusion blocks will be squeezed and retract into the clamping blocks, driving the second spring return rod to move, allowing the second spring return rod to accumulate resilience. When the second spring return rod moves, it will push the rotating frame to rotate, causing the rotating frame to push the sliding block to extend out of the clamping block, moving the sliding block to the bottom of the ingot, driving the spring block to move until the spring block separates from the extrusion block. At this time, since the spring block was in a compressed state before, the resilience of the spring block will be released, causing the spring block to contact the bottom of the ingot and support the bottom of the ingot until the ingot contacts the clamping blocks to clamp the ingot. By making the ingot parallel to the clamping blocks before clamping the ingot, it effectively prevents the ingot from tilting, resulting in a reduced contact area between the extrusion block and the ingot and affecting the clamping stability. At the same time, through the cooperation of the inclined surface pushing blocks, the clamping blocks, and the spring blocks, the conventional clamping of the ingot is changed to grasping, increasing the stability during the hoisting of the ingot.
[0024] (2) During the process of the clamping block clamping the ingot, the present invention will drive the second fixing frame to move, causing the spring arc block to move, enabling the L-shaped rod to slide on the side wall of the concave-convex plate. When the L-shaped rod moves from the concave position of the concave-convex plate to the convex position, the L-shaped rod will be squeezed. The L-shaped rod will push the spring arc block to rotate, causing the spring arc block to accumulate elastic force for return. As the clamping block continues to move, the L-shaped rod will come into contact with the concave position of the concave-convex plate again, and the return elastic force of the spring arc block will be released, driving the spring arc block to quickly return to its original position. At this time, during the return process of the spring arc block, it will come into contact with the joint surface between the ingot and the extrusion block, knocking on the ingot to cause the oxide layer generated after the ingot casting to crack. At the same time, when the roller pushes the inclined plane pushing block to move, the inclined plane pushing block located on the back will also drive the first connecting rod to rotate, causing the first connecting rod to push the sliding plate to rise, driving the blocking block to rise. When the blocking block enters the air intake groove, it will block the air intake groove. At this time, the inside of the fixed frame is in a sealed state, and the sliding plate will squeeze the gas inside the fixed frame. At this time, the squeezed gas will be blocked by the blocking block. Therefore, the gas will generate high pressure. When the notch of the blocking block moves to the position of the air delivery pipe, the air delivery pipe will communicate with the inside of the fixed frame, and the gas will enter the air delivery pipe. The gas will be divided through the shunt pipe, enabling the gas to enter the jet plate evenly. The gas will be sprayed out through the jet plate towards the oxide layer that has been knocked and cracked, separating the oxide layer from the ingot in advance, effectively preventing when the ingot is clamped by the extrusion block, due to the oxide layer being usually hard and brittle, a large clamping force may cause some areas of the oxide layer to crack, which may reduce the contact area between the extrusion block and the ingot, affecting the clamping stability.
[0025] (3) When the sliding plate rises in the present invention, it will drive the first piston rod to rise, causing the first piston rod to squeeze the hydraulic oil in the oil storage pipe. The squeezed hydraulic oil will push the second piston rod to descend, thereby causing the second piston rod to push the push plate to descend. The push plate will push the pressure rod to descend, causing the extrusion plate at the top to descend, causing the second connecting rod at the top to rotate, thereby pushing the rotating plate to rotate, causing the rotating plate to tilt, driving the second connecting rod at the bottom to rotate, thereby causing the extrusion plate at the bottom to rise, bringing the two extrusion plates closer to each other, squeezing the spring return rod three, causing the spring return rod three to accumulate elastic force for return. At the same time, the gas in the extrusion placement groove is squeezed. At this time, the squeezed gas will push the push rod to move, causing the push rod to contact the surface of the ingot. Since the push rod can move freely under the action of gas pressure and can adapt to the surface shape of the ingot, it effectively prevents the surface of the just-cast ingot from being rough, affecting the surface fit between the extrusion block and the ingot, and helps to maintain a good clamping effect.
[0026] (4) When the pushing plate of the present invention descends, it will also drive the third connecting rod to descend, thereby causing the push rod to descend. As the push rod continues to descend, the push rod will contact the spherical rod. The push rod will squeeze the spherical rod, causing the spherical rod to rotate, making the side of the spherical rod in contact with the push rod descend and the other side of the spherical rod ascend, squeezing the arc spring and allowing the arc spring to accumulate resilience. As the spherical rod continues to rotate, the spherical rod will separate from the push rod. At this time, since the weight of the spherical rod is concentrated on the ascending side of the spherical rod, the resilience of the arc spring will also be released, causing the spherical rod to swing up and down rapidly. At this time, high-pressure gas will also enter the air delivery pipe. Through the swing of the spherical rod, local disturbance is generated to the air flow in the air delivery pipe, making the air flow more disordered, thereby enhancing the impact force of the air flow and better separating the oxide layer on the surface of the ingot.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0040] Embodiment 1, please refer to Figure 1 - Figure 4 , the present invention is a clamping tool for casting multiple steel ingots in a row, including a cross beam 1. A lifting arm 11 is fixedly connected to the top of the cross beam 1. Hydraulic cylinders 12 are fixedly connected to both the left and right sides of the cross beam 1. Fixed plates 13 are fixedly connected to the sides of the two hydraulic cylinders 12 close to the cross beam 1. Ten clamping blocks 14 are slidably connected to the bottom of the cross beam 1. The ten clamping blocks 14 are divided into two groups of five. The side walls of the two fixed plates 13 are fixedly connected to the side walls of the two groups of clamping blocks 14. The parts included in the ten clamping blocks 14 are the same;
[0041] The flattening mechanism 2 includes first connecting rods 21 fixedly connected to the front and back of the clamping block 14. Rollers 22 are rotatably connected to the inner walls of the two first connecting rods 21. Inclined plane pushing blocks 23 are arranged on the front and back of the clamping block 14. Connecting plates 24 are arranged on the front and back of the cross beam 1. The tops of the two connecting plates 24 are fixedly connected to the bottom of the cross beam 1. The tops of the two inclined plane pushing blocks 23 are fixedly connected to first spring reset rods 25. The outer walls of the two first spring reset rods 25 are slidably connected to the inner walls of the two connecting plates 24;
[0042] The grasping mechanism 3, the grasping mechanism 3 includes a pressing block 31 slidably connected to the inner wall of the clamping block 14, a second spring return rod 32 is fixedly connected to the side wall of the pressing block 31, and the outer wall of the second spring return rod 32 is slidably connected to the inner wall of the clamping block 14;
[0043] The grasping mechanism 3 further includes a first fixing frame 33 fixedly connected to the side wall of the clamping block 14, a rotating frame 34 is rotatably connected to the inner wall of the first fixing frame 33, the inner wall of the rotating frame 34 is slidably connected to the side wall of the second spring return rod 32, and a sliding block 35 is slidably connected to the inner wall of the clamping block 14;
[0044] Wherein, the side wall of the sliding block 35 is slidably connected to the inner wall of the rotating frame 34, a spring block 36 is slidably connected to the inner wall of the sliding block 35, a knocking assembly 4 is arranged on the inner wall of the clamping block 14, and a pushing assembly 5 is arranged on the inner wall of the pressing block 31. The entire cross beam 1 is hung by the hook of the crane on the lifting arm 11. After the ingot is cast and pushed out of the casting mold, the cross beam 1 is hoisted above the ingot, and then the hydraulic cylinder 12 is started to extend to push the two fixing plates 13 close to the cross beam 1, driving the clamping block 14 to move, making the first connecting rod 21 move, and making the roller 22 contact the inclined surface of the inclined surface pushing block 23. During the continuous movement of the roller 22, the inclined surface of the inclined surface pushing block 23 will be squeezed, causing the two inclined surface pushing blocks 23 to approach each other, driving the first spring return rod 25 to move, and making the first spring return rod 25 accumulate resilience. When the inclined surface pushing block 23 moves and contacts the inclined ingot, it will push the ingot to move until the side wall of the ingot is parallel to the side wall of the clamping block 14. After the ingot is vertical, the roller 22 will separate from the inclined surface of the inclined surface pushing block 23, making the inclined surface pushing block 23 stationary. At the same time, when the clamping block 14 moves, it will also drive the pressing block 31 to move, making the pressing block 31 contact the ingot. At this time, when the clamping block 14 continues to move, the pressing block 31 will be squeezed and retracted into the clamping block 14, driving the second spring return rod 32 to move, making the second spring return rod 32 accumulate resilience. When the second spring return rod 32 moves, it will push the rotating frame 34 to rotate, making the rotating frame 34 push the sliding block 35 to extend out of the clamping block 14, making the sliding block 35 move to the bottom of the ingot, driving the spring block 36 to move until the spring block 36 separates from the pressing block 31. At this time, since the spring block 36 was in a compressed state before, the resilience of the spring block 36 will be released, making the spring block 36 contact the bottom of the ingot and support the bottom of the ingot until the ingot contacts the clamping block 14 and clamps the ingot. By making the ingot parallel to the clamping block 14 before clamping the ingot, it effectively prevents the ingot from tilting, resulting in a reduced contact area between the pressing block 31 and the ingot and affecting the clamping stability. At the same time, through the cooperation of the inclined surface pushing block 23 with the clamping block 14 and the spring block 36, the conventional clamping of the ingot is changed to grasping, increasing the stability during the hoisting of the ingot.
[0045] Example 2, please refer to Figure 5 - Figure 9 , the present invention is a clamping tool for casting multiple steel ingots in a row. On the basis of Example 1, the knocking assembly 4 includes a fixed frame 41 fixedly connected to the inner wall of the clamping block 14. A sliding plate 42 is slidably connected to the inner wall of the fixed frame 41. A first connecting rod 421 is rotatably connected to the bottom of the sliding plate 42. The inner wall of the first connecting rod 421 is rotatably connected to the side wall of the inclined surface pushing block 23 located on the back. Two concave-convex plates 43 are arranged on the side wall of the clamping block 14. The tops of the two concave-convex plates 43 are fixedly connected to the bottom of the cross beam 1;
[0046] Among them, two second fixing frames 44 are fixedly connected to the side of the clamping block 14 away from the first fixing frame 33. A spring arc block 441 is rotatably connected to the inner walls of the two second fixing frames 44. An L-shaped rod 442 is fixedly connected to the side walls of the two spring arc blocks 441. The side walls of the two L-shaped rods 442 are slidably connected to the side walls of the concave-convex plates 43. During the process of the clamping block 14 clamping the steel ingot, it will drive the second fixing frame 44 to move, making the spring arc block 441 move, so that the L-shaped rod 442 slides on the side wall of the concave-convex plate 43. When the L-shaped rod 442 moves from the concave position of the concave-convex plate 43 to the convex position, the L-shaped rod 442 will be squeezed. The L-shaped rod 442 will push the spring arc block 441 to rotate, enabling the spring arc block 441 to accumulate resilience. As the clamping block 14 continues to move, the L-shaped rod 442 will come into contact with the concave position of the concave-convex plate 43 again, and the resilience of the spring arc block 441 will be released, driving the spring arc block 441 to quickly return to its original position. At this time, during the return process of the spring arc block 441, it will contact the joint surface between the steel ingot and the extrusion block 31, knock on the steel ingot, and cause the oxide layer generated after the steel ingot casting is completed to crack.
[0047] The knocking assembly 4 further includes a blocking block 45 fixedly connected to the top of the sliding plate 42. An air inlet groove 451 is opened at the top of the fixed frame 41. The outer wall of the blocking block 45 is slidably connected to the inner wall of the air inlet groove 451. An air delivery pipe 46 is connected through the side wall of the fixed frame 41. Two shunt pipes 461 are connected through the outer wall of the air delivery pipe 46;
[0048] Wherein, a jet plate 47 is fixedly connected to the side of the clamping block 14 away from the first fixing frame 33. The top of the jet plate 47 is in through connection with the bottom of the air delivery pipe 46, and the top of the jet plate 47 is in through connection with the bottoms of two shunt pipes 461. At the same time, when the roller 22 pushes the inclined plane push block 23 to move, the inclined plane push block 23 on the back will also drive the first connecting rod 421 to rotate, so that the first connecting rod 421 pushes the sliding plate 42 to rise, driving the blocking block 45 to rise. When the blocking block 45 enters the air intake groove 451, it will block the air intake groove 451. At this time, the inside of the fixed frame 41 is in a sealed state, and the sliding plate 42 will squeeze the gas inside the fixed frame 41. At this time, the squeezed gas will be blocked by the blocking block 45. Therefore, the gas will generate high pressure.
[0049] The pushing assembly 5 includes a placement groove 51 opened at the inner wall of the extrusion block 31. An oil storage pipe 52 is fixedly connected to the inner wall of the fixed frame 41. A first piston rod 521 is slidably connected to the inner wall of the oil storage pipe 52. A second piston rod 522 is slidably connected to the inner wall of the oil storage pipe 52. Hydraulic oil is provided at the inner wall of the oil storage pipe 52;
[0050] Wherein, the bottom of the first piston rod 521 is fixedly connected to the top of the sliding plate 42. The bottom of the second piston rod 522 is fixedly connected with a pushing plate 53. Two extrusion plates 54 are slidably connected to the inner wall of the placement groove 51. When the sliding plate 42 rises, it will drive the first piston rod 521 to rise, so that the first piston rod 521 squeezes the hydraulic oil in the oil storage pipe 52. The squeezed hydraulic oil will push the second piston rod 522 to descend, so that the second piston rod 522 pushes the pushing plate 53 to descend.
[0051] The pushing assembly 5 further includes a pressure-receiving rod 541 fixedly connected to the top of the top extrusion plate 54. A rotating plate 55 is rotatably connected to the inner wall of the placement groove 51. Two second connecting rods 551 are rotatably connected to the inner wall of the rotating plate 55. The inner walls of the two second connecting rods 551 are rotatably connected to the sides of the two extrusion plates 54 close to the rotating plate 55;
[0052] Wherein, two spring return rods three 56 are fixedly connected to the inner wall of the placement groove 51. The outer walls of the two spring return rods three 56 are slidably connected to the inner walls of the two extrusion plates 54. A plurality of pushing rods 561 are slidably connected to the inner wall of the extrusion block 31. The pushing plate 53 will push the pressure-receiving rod 541 to descend, causing the top extrusion plate 54 to descend, making the top second connecting rod 551 rotate, thereby driving the rotating plate 55 to rotate, causing the rotating plate 55 to tilt, driving the bottom second connecting rod 551 to rotate, so that the bottom extrusion plate 54 rises, and the two extrusion plates 54 approach each other.
[0053] The pushing component 5 further includes a third connecting rod 57 fixedly connected to the top of the pushing plate 53. A push rod 571 is fixedly connected to the bottom of the third connecting rod 57. A spherical rod 58 is rotatably connected to the inner wall of the air delivery pipe 46. An arc-shaped spring 581 is fixedly connected to the bottom of the spherical rod 58. One side of the arc-shaped spring 581 away from the spherical rod 58 is fixedly connected to the outer wall of the air delivery pipe 46. When the pushing plate 53 descends, it will also drive the third connecting rod 57 to descend, thereby causing the push rod 571 to descend. As the push rod 571 continuously descends, the push rod 571 will contact the spherical rod 58. The push rod 571 will squeeze the spherical rod 58, causing the spherical rod 58 to rotate, making the side of the spherical rod 58 in contact with the push rod 571 descend, and the other side of the spherical rod 58 ascend.
[0054] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding connection positions of the components.
[0055] The usage method of this clamping tooling includes the following steps:
[0056] S1: Equipment installation: Hang the entire crossbeam 1 on the lifting arm 11 through the hook of the crane.
[0057] S2: Ingot straightening: Hoist the crossbeam 1 above the ingot, and then start the hydraulic cylinder 12 to extend and drive the clamping block 14 to move, so that the roller 22 contacts the inclined surface of the inclined surface pushing block 23 and squeezes the inclined surface of the inclined surface pushing block 23, causing the two inclined surface pushing blocks 23 to approach each other. When the inclined surface pushing block 23 moves and contacts the inclined ingot, it will push the ingot to move until the side wall of the ingot is parallel to the side wall of the clamping block 14.
[0058] S3: Ingot clamping: After the ingot is straightened, the clamping block 14 continues to move and contacts the ingot to clamp the ingot.
[0059] A specific application of this embodiment is as follows: When the present invention is in use, the entire crossbeam 1 is hung on the lifting arm 11 of a crane by a hook. After the ingot is cast and pushed out of the casting mold, the crossbeam 1 is hoisted above the ingot. Then, the hydraulic cylinder 12 is activated to extend, pushing the two fixing plates 13 closer to the crossbeam 1, driving the clamping block 14 to move, causing the connecting rod 21 to move, and making the roller 22 contact the inclined surface of the inclined surface pushing block 23. During the continuous movement of the roller 22, the inclined surface of the inclined surface pushing block 23 will be squeezed, causing the two inclined surface pushing blocks 23 to approach each other, driving the spring return rod 25 to move, and allowing the spring return rod 25 to accumulate elastic force. When the inclined surface pushing block 23 contacts the inclined ingot during movement, it will push the ingot to move until the side wall of the ingot is parallel to the side wall of the clamping block 14. After the ingot is vertical, the roller 22 will separate from the inclined surface of the inclined surface pushing block 23, keeping the inclined surface pushing block 23 in a static state. At the same time, when the clamping block 14 moves, it will also drive the extrusion block 31 to move, making the extrusion block 31 contact the ingot. At this time, as the clamping block 14 continues to move, the extrusion block 31 will be squeezed and retract into the clamping block 14, driving the spring return rod 32 to move, allowing the spring return rod 32 to accumulate elastic force. When the spring return rod 32 moves, it will push the rotating frame 34 to rotate, causing the rotating frame 34 to push the sliding block 35 to extend from the clamping block 14, making the sliding block 35 move to the bottom of the ingot, driving the spring block 36 to move until the spring block 36 separates from the extrusion block 31. At this time, since the spring block 36 was in a compressed state before, the elastic force of the spring block 36 will be released, causing the spring block 36 to contact the bottom of the ingot and support the bottom of the ingot until the ingot contacts the clamping block 14 and clamps the ingot. By making the ingot parallel to the clamping block 14 before clamping the ingot, it effectively prevents the ingot from tilting, resulting in a reduced contact area between the extrusion block 31 and the ingot and affecting the clamping stability. At the same time, through the cooperation of the inclined surface pushing block 23 with the clamping block 14 and the spring block 36, the conventional clamping of the ingot is changed to grasping, increasing the stability during the hoisting of the ingot;
[0060] Secondly, during the process of the clamping block 14 clamping the ingot, it will drive the second fixing frame 44 to move, causing the spring arc block 441 to move, and enabling the L-shaped rod 442 to slide on the side wall of the concave-convex plate 43. When the L-shaped rod 442 moves from the concave position of the concave-convex plate 43 to the convex position, the L-shaped rod 442 will be squeezed. The L-shaped rod 442 will push the spring arc block 441 to rotate, causing the spring arc block 441 to accumulate resilience. As the clamping block 14 continues to move, the L-shaped rod 442 will come into contact with the concave position of the concave-convex plate 43 again, and the resilience of the spring arc block 441 will be released, driving the spring arc block 441 to quickly return to its original position. At this time, during the return process of the spring arc block 441, it will contact the joint surface between the ingot and the extrusion block 31, strike the ingot, causing the oxide layer generated after the ingot casting is completed to crack. At the same time, when the roller 22 pushes the inclined plane push block 23 to move, the inclined plane push block 23 located on the back will also drive the first connecting rod 421 to rotate, causing the first connecting rod 421 to push the sliding plate 42 to rise, driving the blocking block 45 to rise. When the blocking block 45 enters the air intake groove 451, it will block the air intake groove 451. At this time, the inside of the fixed frame 41 is in a sealed state, and the sliding plate 42 will squeeze the gas inside the fixed frame 41. At this time, the squeezed gas will be blocked by the blocking block 45. Therefore, the gas will generate high pressure. When the notch of the blocking block 45 moves to the position of the air delivery pipe 46, the air delivery pipe 46 will be connected to the inside of the fixed frame 41, and the gas will enter the air delivery pipe 46. The gas will be split through the shunt pipe 461, enabling the gas to evenly enter the jet plate 47 and be ejected from the jet plate 47 against the cracked oxide layer, separating the oxide layer from the ingot in advance. This effectively prevents the oxide layer from being partially cracked due to the relatively hard and brittle nature of the oxide layer and the large clamping force when the ingot is clamped by the extrusion block 31, which may reduce the contact area between the extrusion block 31 and the ingot and affect the clamping stability;
[0061] Among them, after the spring arc block 441 strikes the ingot, the clamping block 14 continues to move, and the spring arc block 441 will be pushed by the ingot to rotate. At this time, the L-shaped rod 442 is in the concave position of the concave-convex plate 43, and there is no convexity in front of the concave-convex plate 43. Therefore, the spring arc block 441 can rotate smoothly until the spring arc block 441 separates from the contact surface between the ingot and the extrusion block 31, enabling the extrusion block 31 to smoothly contact the ingot;
[0062] Secondly, when the sliding plate 42 rises, it will drive the first piston rod 521 to rise, causing the first piston rod 521 to squeeze the hydraulic oil in the oil storage pipe 52. The squeezed hydraulic oil will push the second piston rod 522 to descend, thereby causing the second piston rod 522 to push the push plate 53 to descend. The push plate 53 will push the compression rod 541 to descend, causing the extrusion plate 54 at the top to descend, making the second connecting rod 551 at the top rotate, thereby pushing the rotating plate 55 to rotate, causing the rotating plate 55 to tilt, driving the second connecting rod 551 at the bottom to rotate, thereby causing the extrusion plate 54 at the bottom to rise, bringing the two extrusion plates 54 closer to each other, squeezing the third spring return rod 56, causing the third spring return rod 56 to accumulate resilience. At the same time, the gas in the extrusion placement groove 51 is squeezed. At this time, the squeezed gas will push the push rod 561 to move, causing the push rod 561 to contact the surface of the ingot. Since the push rod 561 can move freely under the action of gas pressure and can adapt to the surface shape of the ingot, it can effectively prevent the surface of the just-cast ingot from being rough, which affects the fitting of the extrusion block 31 to the surface of the ingot, and helps to maintain a good clamping effect;
[0063] Secondly, when the push plate 53 descends, it will also drive the third connecting rod 57 to descend, thereby causing the push rod 571 to descend. As the push rod 571 continues to descend, the push rod 571 will contact the spherical rod 58. The push rod 571 will squeeze the spherical rod 58, causing the spherical rod 58 to rotate, making the side of the spherical rod 58 in contact with the push rod 571 descend, and the other side of the spherical rod 58 to rise, squeezing the arc spring 581, causing the arc spring 581 to accumulate resilience. As the spherical rod 58 continues to rotate, the spherical rod 58 will separate from the push rod 571. At this time, since the weight of the spherical rod 58 is concentrated on the rising side of the spherical rod 58, the resilience of the arc spring 581 will also be released, causing the spherical rod 58 to swing up and down rapidly. At this time, high-pressure gas will also enter the gas transmission pipe 46. Through the swing of the spherical rod 58, local disturbance is generated to the air flow in the gas transmission pipe 46, making the air flow more disordered, thereby enhancing the impact force of the air flow and better separating the oxide layer on the surface of the ingot.
