Description

Technical Field

[0001] The invention relates to the technical field related to resistance welding, and in particular to a three-point simultaneous resistance welding device. Background Art

[0002] Resistance welding is a method of using the resistance heat generated by the current passing through the weldment and the contact as a heat source to locally heat the weldment to a molten or plastic state, and pressurize it for welding. No filler metal is required during the welding process, and the weldment has little deformation. Resistance welding methods are divided into many types, including spot welding, seam welding, projection welding and butt welding, which are widely used.

[0003] For example, announcement number CN219425912U discloses a resistance welding device, including a top plate, a displacement plate, a bottom plate, an extension plate, a second servo electric cylinder, a first welding electrode, and a second welding electrode. Linear slide rails are provided at the lower sides of both ends of the bottom of the displacement plate, and two groups of linear sliders are sleeved on the outside of each group of the linear slide rails. The tops of the two groups of linear sliders that are far away from each other are fixedly connected to an arch plate by connecting bolts. A servo motor is provided at one end of the top of the arch plate through a fixing seat. The output shaft of the servo motor is connected to a guide wheel, and the bottom of the guide wheel passes through a strip-shaped reserved groove opened at one end of the top of the arch plate. This new type has two groups of welding structures with adjustable height and spacing, which can facilitate the welding of metal cans with the same spacing between the top and bottom parts, and can facilitate the welding of metal cans with different diameters. It has good flexibility during welding and high welding efficiency, and is suitable for wide promotion and use.

[0004] For example, announcement number CN218016354U discloses a hydraulic resistance welding device, which includes a frame; a first hydraulic cylinder, which is arranged on one side of the frame; a second hydraulic cylinder, which is located on the other side of the frame and works synchronously with the first hydraulic cylinder, and its output end is arranged opposite to the output end of the first hydraulic cylinder; a first electrode assembly, which is connected to the output end of the first hydraulic cylinder; a second electrode assembly, which is connected to the output end of the second hydraulic cylinder, and the second electrode assembly cooperates with the first electrode assembly; a hydraulic pump station, which is connected to the first hydraulic cylinder and the second hydraulic cylinder. The resistance welding device can synchronously weld the workpiece while squeezing and flattening the workpiece, thereby realizing vacuum sealing welding with good sealing effect;

[0005] However, the existing resistance welding device still has the following shortcomings:

[0006] 1. The existing resistance welding device can only perform welding operation on a single point of the workpiece during the welding process. When welding multiple points of the workpiece, it needs to be divided into multiple steps for welding operation, which affects the welding efficiency of the workpiece and consumes more manpower;

[0007] 2. The existing resistance welding device generates welding fumes during the welding process, which diffuse outward and pollute the surrounding environment. Operators inhale a large amount of welding fumes during long-term work, which affects their health.

[0008] 3. The existing resistance welding device will cause sparks to fly outward during welding, and the protection effect is poor.

[0009] Therefore, we propose a three-point simultaneous resistance welding device to solve the above problems. Summary of the invention
