Description

Technical Field

[0001] This application relates to the technical field of strip steel processing, and particularly to an integrated machine for cutting and welding the ends of strip steel. Background Art

[0002] Strip steel is a narrow and long steel plate produced by various rolling mills to meet the needs of different industrial sectors for industrial production of various metal or mechanical products. Strip steel is also called steel strip. Usually, when the steel strip enters a machine tool or stamping machine for processing, it is in a coiled state. After the steel strip is laid flat for a certain length for processing, when a coil of steel strip is processed, another coil of steel strip needs to be placed in the same position for processing. To ensure the continuous processing of the steel strip, when the first coil of steel strip is about to be processed, it needs to be welded to the second coil of steel strip about to be processed, that is, the tail of the first coil of steel strip is connected to the head of the second coil of steel strip by welding to form an integral body.

[0003] The utility model patent with the publication number CN216227733U proposes a strip steel welding operation platform, including a welding platform. A pressing component is arranged on the welding platform. The pressing component includes a pressing plate located above the welding platform. A welding interface is opened on the pressing plate. Two connecting rods are fixed on one side of the pressing plate close to the welding platform. The two connecting rods are respectively located on both sides of the welding interface. The bottom end of the connecting rod is fixed with a connecting plate. A driving member for driving the connecting plate to move vertically is arranged below the welding platform.

[0004] For the above strip steel welding operation platform, the two strip steels are pressed by the pressing component, and there is no need to manually press the strip steel and then perform welding. However, it is not convenient to weld the lower surface of the strip steel. When welding the lower surface, the strip steel needs to be lifted, resulting in the problem of reduced welding efficiency. Utility Model Content

[0005] The purpose of the present utility model is to solve or at least alleviate the problem of the existing strip steel welding operation platform, in which the two strip steels are pressed by the pressing component, without manually pressing the strip steel and then performing welding. However, it is not convenient to weld the lower surface of the strip steel. When welding the lower surface, the strip steel needs to be lifted, resulting in the problem of reduced welding efficiency.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] A strip steel end cutting and welding integrated machine, including an operating table, on which there is a cutting component for cutting strip steel and a welding component for connecting the strip steel at both ends. The welding component includes a through groove opened on the upper surface of the operating table. One side side wall of the operating table is fixedly connected with an L-shaped fixing plate. The side wall of the L-shaped fixing plate far away from the operating table is fixedly connected with a stepping motor. The output end of the stepping motor penetrates through the L-shaped fixing plate and is fixedly connected with a mounting plate. At the top end of one side wall of the mounting plate, there is a threaded rod, and the threaded rod penetrates through the mounting plate and forms a threaded connection. There is a rotating component on the mounting plate for driving the threaded rod to rotate. One end of the threaded rod close to the operating table is rotatably connected with an intelligent welding machine. Below the threaded rod, there is a positioning rod. One end of the positioning rod penetrates through the mounting plate and is fixedly connected with the intelligent welding machine. The intelligent welding machine is located directly above the through groove.

[0008] By adopting the above technical solutions, during use, when the strip steel is conveyed to the processing equipment and passes through the operating table, when the strip steel is completely conveyed, the cutting component cuts the tail end of the strip steel and then moves it to the through groove. Then, the head end of another strip steel is cut and moved to the through groove. The head and tail ends of the two strip steels are butted. Then, the rotating component drives the threaded rod to rotate, so that the threaded rod moves on the mounting plate, driving the intelligent welding machine to move. At the same time, the intelligent welding machine is started, and the welding end of the intelligent welding machine welds the upper surface of the connection of the two strip steels. When the upper surface is welded, the intelligent welding machine is made to approach the mounting plate through the threaded rod. Then, the stepping motor is started to rotate 180 degrees, rotating the mounting plate and flipping the intelligent welding machine. Then, the threaded rod is rotated again to move the intelligent welding machine to weld the lower surface of the connection of the two strip steels, thus avoiding as much as possible the problem that when welding the lower surface, the strip steel needs to be lifted, resulting in a reduction in welding efficiency.

[0009] Optionally, the cutting component includes a receiving groove opened on the upper surface of the operating table on one side of the through groove. A cutting table is arranged in the receiving groove. The lower surface of the operating table is fixedly connected with a first cylinder. The output end of the first cylinder penetrates through the operating table and is fixedly connected with the bottom end of the cutting table. Above the cutting table on the upper surface of the operating table, there is a U-shaped frame fixedly connected. An electric slide rail is fixedly connected to the upper surface of the U-shaped frame. An electric slider is slidably connected to the upper surface of the electric slide rail. A cutting machine is fixedly connected to the upper surface of the electric slider. A cutting groove is opened at the top end of the cutting table. The blade of the cutting machine is adapted to the cutting groove.

[0010] By adopting the above technical solution, one end of the strip is moved to the cutting table, and then the first cylinder is started to push the cutting table to rise, so that the cutting table clamps the strip between the cutting table and the U-shaped frame for fixation. Then, when the electric slide rail is started to drive the cutting machine to move, the cutting machine is started at the same time, so that the blade of the cutting machine moves in the cutting groove to cut the strip and make the end of the strip flat.

[0011] Optionally, the rotating assembly includes a positive and negative motor fixedly connected to one side wall of the mounting plate. The output end of the positive and negative motor is fixedly connected with a first gear. A second gear is sleeved on the threaded rod. The second gear is threadedly connected with the threaded rod. The second gear meshes with the first gear. An annular groove is formed on one side wall of the second gear close to the mounting plate. A circular ring is rotatably connected in the annular groove. Two parallel fixed rods are fixedly connected to one side wall of the circular ring close to the mounting plate. The end of the fixed rod away from the circular ring is fixedly connected with the mounting plate.

[0012] By adopting the above technical solution, by starting the positive and negative motor to drive the first gear to rotate, the second gear can be rotated, so that the threaded rod rotates and moves on the mounting plate. At the same time, the second gear can be positioned through the annular groove, the circular ring and the fixed rod, preventing the second gear from moving when the threaded rod moves and causing the second gear to disengage from the first gear.

[0013] Optionally, two vertically arranged first guide rods are fixedly connected to the upper surface of the operating table on one side of the through groove. The top ends of the first guide rods are fixedly connected with an operating plate. A second cylinder is fixedly connected to the upper surface of the operating plate. The output end of the second cylinder penetrates through the operating plate and is fixedly connected with a U-shaped pressing plate. The U-shaped pressing plate is sleeved on the first guide rods.

[0014] By adopting the above technical solution, by starting the second cylinder to press down the U-shaped pressing plate, the U-shaped pressing plate can press the strip down on the operating table to prevent the strip from shaking during welding.

[0015] Optionally, second guide rods are arranged on the upper surfaces of both ends of the U-shaped pressing plate away from the second cylinder. One end of the second guide rod penetrates through the U-shaped pressing plate and is fixedly connected with the operating table.

[0016] By adopting the above technical solution, the second guide rods can improve the stability of the U-shaped pressing plate during descent and prevent the U-shaped pressing plate from tilting.

[0017] Optionally, guide rollers are rotatably connected to both ends of the upper surface of the operating table.

[0018] By adopting the above technical solution, the guide rollers can improve the conveying efficiency of the strip on the operating table and reduce the friction between the strip and the operating table.

[0019] Optionally, a same limiting block is rotatably connected to one ends of the threaded rod and the positioning rod away from the intelligent welding machine.

[0020] By adopting the above technical solutions, the limiting block can prevent the threaded rod from screwing out of the second gear.

[0022] 1. Through the cooperative setting among structures such as the stepping motor, the mounting plate, and the threaded rod, during use, when the strip steel is conveyed to the processing equipment, it passes through the operating table. When the strip steel is completely conveyed, the cutting component cuts the tail end of the strip steel and then moves to the through groove. Then, the head end of another strip steel is cut and moved to the through groove, and the head and tail ends of the two strip steels are butted. Then, the rotating component drives the threaded rod to rotate, causing the threaded rod to move on the mounting plate, driving the intelligent welding machine to move. At the same time, the intelligent welding machine is started, so that the welding end of the intelligent welding machine welds the upper surface of the connection of the two strip steels. When the upper surface is welded, the intelligent welding machine is brought close to the mounting plate through the threaded rod. Then, the stepping motor is started to rotate 180 degrees, rotating the mounting plate to flip the intelligent welding machine. Then, the threaded rod is rotated to move the intelligent welding machine to weld the lower surface of the connection of the two strip steels, thus avoiding as much as possible the problem that when welding the lower surface, the strip steel needs to be lifted, resulting in a reduction in welding efficiency;

[0023] 2. One end of the strip steel is moved to the cutting table, and then the first air cylinder is started to push the cutting table to rise, so that the cutting table clamps the strip steel between the cutting table and the U-shaped frame for fixation. Then, the electric slide rail is started to drive the cutting machine to move while the cutting machine is started, so that the blade of the cutting machine moves in the cutting groove to cut the strip steel, making the end of the strip steel flat.

The stepping motor 4 is fixedly connected to the side wall of the L-shaped fixing plate 3 away from the operating table 1. The mounting plate 5 is arranged on the side wall of the L-shaped fixing plate 3 away from the stepping motor 4. The output end of the stepping motor 4 penetrates through the L-shaped fixing plate 3 and is fixedly connected to the mounting plate 5. The threaded rod 6 is arranged at the top of one side wall of the mounting plate 5. The threaded rod 6 penetrates through the mounting plate 5 and forms a threaded connection. A rotating assembly for driving the threaded rod 6 to rotate is provided on the mounting plate 5.

[0032] During use, when the strip steel is conveyed to the processing equipment, it passes through the operation table 1. When the conveying of the strip steel is completed, the cutting assembly cuts the tail end of the strip steel and then moves to the through slot 2. After cutting the head end of another strip steel, it moves to the through slot 2. The head and tail ends of the two strip steels are butted. Then, the rotation assembly drives the threaded rod 6 to rotate, causing the threaded rod 6 to move on the mounting plate 5, driving the intelligent welding machine 7 to move. At the same time, the intelligent welding machine 7 is started, and the welding end of the intelligent welding machine 7 welds the upper surface of the connection of the two strip steels. When the upper surface welding is completed, the intelligent welding machine 7 is brought close to the mounting plate 5 by the threaded rod 6. Then, the stepping motor 4 is started to rotate 180 degrees, rotating the mounting plate 5 to flip the intelligent welding machine 7. Then, the threaded rod 6 is rotated to move the intelligent welding machine 7 to weld the lower surface of the connection of the two strip steels, thus avoiding as much as possible the problem that the strip steel needs to be lifted when welding the lower surface, resulting in a reduction in welding efficiency.

[0033] Refer to Figure 1 and Figure 2 As shown in FIGS.

Two parallel fixed rods 22 are fixedly connected to one side wall of the ring 21 close to the mounting plate 5. The end of the fixed rod 22 far from the ring 21 is fixedly connected with the mounting plate 5. By starting the positive and negative motor 17 to drive the first gear 18 to rotate, the second gear 19 can be rotated, so that the threaded rod 6 rotates and moves on the mounting plate 5. At the same time, the second gear 19 can be positioned through the annular groove 20, the ring 21 and the fixed rod 22, preventing the second gear 19 from moving when the threaded rod 6 moves and causing the second gear 19 to disengage from the first gear 18.

[0035] Refer to Figure 1 , on the upper surface of the operating table 1, two vertically arranged first guide rods 23 are fixedly connected on one side of the through groove 2. The top ends of the first guide rods 23 are fixedly connected with an operating plate 24. A second cylinder 25 is fixedly connected to the upper surface of the operating plate 24. The output end of the second cylinder 25 penetrates through the operating plate 24 and is fixedly connected with a U-shaped pressing plate 26.

The second guide rods 27 can improve the stability of the U-shaped pressing plate 26 when it descends and prevent the U-shaped pressing plate 26 from tilting.

[0037] Refer to Figure 1 , guide rollers 28 are rotatably connected to both ends of the upper surface of the operating table 1. The guide rollers 28 can improve the conveying efficiency of the strip steel on the operating table 1 and reduce the friction between the strip steel and the operating table 1.

[0038] Refer to Figure 1 , the threaded rod 6 and the positioning rod 8 are rotatably connected to the same limiting block 29 at the end far from the intelligent welding machine 7. The limiting block 29 can prevent the threaded rod 6 from screwing out of the second gear 19.

[0039] The implementation principle of this application is as follows: When in use, the strip steel passes through the operation table 1 when being conveyed to the processing equipment. When the conveyance of the strip steel is completed, the tail end of the strip steel is moved to the cutting table 10, and then the first cylinder 11 is started to push the cutting table 10 to rise, so that the cutting table 10 clamps the strip steel between the cutting table 10 and the U-shaped frame 12 for fixation. Then, the electric slide rail 13 is started to drive the cutter 15 to move while the cutter 15 is started, so that the blade of the cutter 15 moves in the cutting groove 16 to cut the strip steel, making the end of the strip steel flat. Then, the cut end is moved to the through groove 2, and the head end of another strip steel is cut and then moved to the through groove 2. The head and tail ends of the two strip steels are butted. Then, by starting the forward and reverse motor 17 to drive the first gear 18 to rotate, the second gear 19 can be rotated, so that the threaded rod 6 rotates and moves on the mounting plate 5, driving the intelligent welding machine 7 to move. At the same time, the intelligent welding machine 7 is started, and the welding end of the intelligent welding machine 7 welds the upper surface of the connection of the two strip steels. When the upper surface welding is completed, the intelligent welding machine 7 is brought close to the mounting plate 5 by the threaded rod 6. Then, the stepping motor 4 is started to rotate 180 degrees to rotate the mounting plate 5, so that the intelligent welding machine 7 is flipped. Then, the threaded rod 6 is rotated to move the intelligent welding machine 7 to weld the lower surface of the connection of the two strip steels, thus avoiding as much as possible the problem that the strip steel needs to be lifted when welding the lower surface, resulting in a reduction in welding efficiency.
