Audited Supplier Automatic Steel Drum Longitudinal Seam Welding Machine
Overview
"Inverter automatic steel drum seam welder" (hereinafter referred to as seam welder) is an important device for producing metal drums. Its working principle belongs to the scope of resistance welding: that is, after the workpieces are assembled, the electrode applies pressure and the current flows through the steel plate. The contact area of the overlap and the adjacent area generate resistance heat, thereby forming a series of overlapped nuggets to obtain an airtight weld.
The welding method adopted by this equipment is roll seam welding. The electrode is a cylindrical roller. Its width is larger than the overlap of the steel plate to control the thickness of the joint. Welding uses a large electrode pressure and continuous welding current. By controlling welding specifications, including parameters such as electrode pressure, welding current, and welding speed, stable welding quality can be obtained, and seam welding procedures for longitudinal welds with a diameter of 560mm to 571.6mm can be completed.

Operation Flow
Manually put the cut sheet on the pedal, and automatically transfer it to the automatic slitter. After being automatically conveyed into the machine and rolled into a cylindrical shape, the spot welding is not necessary, that is, the steel drum is longitudinally welded. Seam welding, automatic unloading.
Process flow
Manually put the cut material on the pallet---Use the forklift (travel) on the feeding roller---automatic feeding by the suction cup---cut the edge (trimming) by the trimmer---to the rolling area- --Rolling---Drum walking---Welding area---Welding---Welding completed---Scissor tongue---Automatic unloading---Repeat the above actions.
Pneumatic system, cooling system and lubrication system
Compressed air is used as the power source for the feeding of the seam welding machine, the axial movement of the electrode wheel, the generation of electrode pressure, and the discharge of materials.
The seam welding machine is equipped with corresponding cooling system and lubrication system. The lubrication system is divided into conductive grease lubrication part and ordinary grease lubrication part. The two parts are automatically supplied with grease by their respective dry oil pumps. The cooling system is cold water cooling, which can be cooled by cold water tank cooling, or the water can be filtered through the water tank circulation, and the water can be cooled by natural air flow. When cooling with a water cooler, it is recommended not to cool the water temperature too low. Generally, the inlet water temperature is controlled at about 20°C in summer. If the inlet water temperature is too low, condensation will occur on the components with water cooling pipes inside the transformer, and there will be water for a long time. Condensation adversely affects the insulation of components such as transformers, destroys the insulation performance of conductive components, and shortens the service life of components.
Electronic control
It adopts Mitsubishi PLC programming controller and man-machine interface. The entire operating system is controlled by the latest technology touch control, full local language display, direct display of the cause of failure, convenient and fast maintenance, no special training is required. The operating system is divided into threemajor operation modes: automatic cycle operation; step operation; segment operation.
Air control
Much of the seam welding machines technilogical actionuses compressed air as the power source. After passing through various valves, the relevant parts are driven by the cylinder to achieve actions and functions. This equipment increases the pressure of the workpiece feed roller less than the pressure of normal seam welding.
