Product Description

Fully Automatic Sheet Rolling Feeding  Longitudinal Steel Drum Welding Machine

 

Machine Description

Option 1 Fully Automatic Longitudinal Seam Welding Machine
"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.
The operation flow of this equipment: 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.

Working Process

Suction cup automatically feeds to the rolling area---Rolling---rolled drum movement---welding area---welding---welded---Cutting--auto unloading---repeat the above actions

The rolling and welding process is divided into four process steps: feeding, trimming, rolling, welding, and unloading; the advancing direction of the feed is perpendicular to the forming axis of the parts at each station of rolling and welding coaxial, unloading is parallel to the previous step. The area requirement is not less than 10X7m2

Auto Feeding 
Cutted sheets are stacked on the rack to be loaded, and then the sheets are conveyed into the rolling device one by one through a vacuum suction cup.

Conveying and pushing part:
The cylindrical workpiece is pushed to the welding station for a short time by the pawl of the conveying part, and waits. After the welding of the workpiece at the welding station, the electrical automatic control part sends a signal, and the pushing part can push the workpiece from the to-be-welded station to the welding station again, and then cycle.
After the welding of the front workpiece is completed, the pushing part can be started, and the workpiece is slowly advanced to bring the workpiece into the welding state. Then, quickly return to the orginal position and wait for the next cycle.


Overlap control part:
 'Z' Chute and shaping block are important basic components to determine the edge overlap and ensure stable welding. The edge overlap of this seam welding machine is 3mm. Adjust the thickness of the clips to adjust the edge overlap. It is centered by three waist drum wheels to control and ensure a stable and consistent amount of overlap.

Part II  Workflow, welding principle, structure

1. Workflow
The welder is mainly composed of six parts (automatic suction, automatic rolling, automatic tank feeding, automatic welding, automatic unloading). The working flow is as follows: the cut qualified sheet metal is neatly placed on the material table, and the automatic suction device is sent to the round machine garden, and the tank feeding mechanism sends the round barrel body to the welding position for welding. Deliver the welded barrel body to the next process from the tank body.                                                 
   
2. Welding principles
By using the principle of resistance seam welding, using special copper alloy conductor and low voltage and high current welding technology, the welding machine uses the current between the upper and lower electrodes to produce a short time high heat to melt the welding place. Under high pressure forging, the metal molecules in the welding area are rearranged and crystallized and cooled gradually to realize welding.

3. Structure:
The main body of the equipment adopts frame structure, which can effectively increase the heat dissipation area, simplify the structure reasonably, and facilitate adjustment and maintenance. main mechanism including electrode assembly, mechanical transmission system, electrical control (PLC, touch screen) and other systems.
