Description

Technical Field

[0001] The present invention relates to the technical field of splicing equipment, and particularly relates to a stabilizing device for the splicing welding of thin steel plates. Background Art

[0002] During the welding process of two thin steel plates, the temperature generated during welding will cause uneven heating at the splicing joint of the thin steel plates, resulting in deformation or even curling during the welding process. The deformation of the steel plate during welding will lead to a reduction in the overall load-bearing capacity.

[0003] In the prior art, a pressing block is usually directly used to squeeze the splicing joint to reduce the deformation phenomenon of the splicing welding of thin steel plates. However, the anti-deformation effect is general, the welding quality cannot be guaranteed, and the welding precision is affected. For this reason, we propose a stabilizing device for the splicing welding of thin steel plates. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stabilizing device for the splicing welding of thin steel plates. By setting a conveying component to convey two thin steel plates to be spliced and welded to a suitable position, and then clamping the two thin steel plates by a clamping member to limit the spacing of the splicing joint for better welding. Then, a rigid pressure is applied to the splicing joint by a splicing pressing component, and the distance between the pressing blocks can be adjusted according to different requirements, with better compatibility. When the connecting frame moves upward in contact with the thin steel plate, the laser welding head above can be exposed, so that welding can be realized. During the upward movement of the connecting frame, the channel sealed by the cover in the perfusion component of the pressing block moves from the closed area to the water injection port area, and starts to perfusion water into the pressing block to increase the weight of the pressing block, so that the splicing joint of the pressed steel plate is pre-deformed to offset the residual deformation after welding.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to the attached Figure 1-6 , a stabilizing device for the butt welding of thin steel plates, comprising a workbench 1, which is stably placed at a suitable installation position. A conveying assembly 2 is installed on the workbench 1. The conveying assembly 2 includes a pair of brackets 21 that are horizontally spaced apart from each other. A conveyor belt is installed on one side of each bracket 21. It can be understood that the conveyor belt is installed on the side close to the center of the two brackets 21. In this way, a thin steel plate is placed on the two conveyor belts at the same time and is conveyed along the extending direction of the conveyor belt. During the operation, the staff will place two thin steel plates on the conveying assembly 2 successively and transport the thin steel plates to the welding position.

[0032] Two groups of clamping members 22 are installed on one of the brackets 21 at a position far from the thin steel plate loading area. The number of each group of clamping members 22 is two. The distance between the two clamping members 22 in the same group is adapted to the length of the thin steel plate to improve the stability when clamping the steel plate. In some embodiments, the clamping members 22 are selected as jaw cylinders, which are convenient for installation and operation. It can be understood that two groups of clamping members 22 are installed on both brackets, which can further enhance the stability of clamping the thin steel plate.

[0033] A butt joint pressing assembly 3 is also installed on the workbench 1, which includes a guide rail frame 31 installed on one side of the bracket 21. A linear module is installed horizontally on the guide rail frame 31. The track of the linear module crosses above the bracket 21. An actuating cylinder is installed on the moving slider of the linear die. A connecting frame 32 is installed on the push head of the actuating cylinder. One side wall of the connecting frame 32 is slidably connected to the push head. Two spaced slide rods 33 are respectively connected to the inner walls of both sides of the connecting frame 32. Displacement members 34 are respectively slid on the left and right ends of the two slide rods 33, and a pressing block 35 is installed on each displacement member 34. It can be understood that the pressing blocks 35 at both ends respectively press on the butt joint positions of the two thin steel plates to limit the deformation of the steel plate butt joint after welding.

[0034] In some embodiments, positioning posts are installed on the top of the pressing blocks 35, and one end of a connecting rod 36 is rotatably connected to the positioning posts. A rotating member 37 is also provided between the two pressing blocks 35, and connecting posts are respectively provided at both ends of the rotating member 37. The other end of the connecting rod 36 of one pressing block 35 is rotatably connected to the connecting post at one end of the rotating member 37, and the other end of the connecting rod 36 of the other pressing block 35 is rotatably connected to the connecting post at the other end of the rotating member 37. The two pressing blocks 35 can approach or move away from each other synchronously, improving the synchronism of the movement of the pressing blocks 35, being able to adapt to steel plates with different seam requirements, and enhancing compatibility.

[0035] A fixing plate 5 is also installed on the push head above the connecting frame 32. A laser welding head 6 is installed on the fixing plate 5, and the fixing plate 5 is provided with a through groove. The laser welding head 6 extends out from the through groove. It can be understood that through grooves for the laser welding head 6 to extend out are provided on both the connecting frame 32 and the rotating frame, so as to facilitate laser welding to perform welding operations on the seam.

[0036] The inside of the pressing block 35 is hollow, and liquid can be poured into its interior. A perfusion assembly 4 is installed on one side of the pressing block 35, including a plastic part 41 extending outward from the side wall of the pressing block 35. Slide rails are provided on both sides of the plastic part 41. A sealing cover 42 is slidably fitted on the plastic. A water injection port 43 is provided in the lower part area of the plastic part 41, and the water injection port 43 is communicated with the inside of the pressing block 35. Correspondingly, a water pipe connection port 44 is provided on the outer side of the sealing cover 42. A water bucket or a water conveying device is connected through a pipeline. A channel 45 is formed by the inward extension of the inner side of the sealing cover 42. When the channel 45 moves to the water injection port 43, water flows into the inside of the pressing block 35 through the water injection port 43. On the contrary, when the channel 45 moves to the area other than the water injection port 43, water cannot flow into the inside of the pressing block 35. In some embodiments, a rubber sealing ring is also sleeved on the outer wall of the channel 45 to improve the sealing performance.

[0037] In some embodiments, the same telescopic rod 46 is connected between the sealing covers 42 of the pressing blocks 35 on the same side, and the telescopic rod 46 is connected to the bottom of the fixing plate 5 through a vertical rod. When the pressing block 35 drops and touches the thin steel plate, at this time, the actuating cylinder will continue to descend, and the connecting frame 32 where the pressing block 35 is located will slide upward, so that the laser welding head 6 is exposed to the seam, facilitating the laser welding head 6 to weld the seam of the two thin steel plates. At the same time, the vertical rod will push the telescopic rod 46 to horizontally move downward, that is, the sealing cover 42 and the plastic part 41 are closed, and the channel 45 inside the sealing cover 42 is aligned with the water injection port 43, and water starts to be poured into the inside of the pressing block 35, gradually increasing the own weight of the pressing block 35, so that the seam of the thin steel plate is pre-deformed by force, used to offset the residual deformation after welding, enabling the workpiece to return to the geometric shape and size required by the design, and avoiding the collapse of the seam after welding.
