Three Phase Seam Welder for Stainless Steel Drum

Three Phase Seam Welder for Stainless Steel Drum“Three-phase Seam Welder”

(hereinafter referred to as seam welder) is one of the important and key equipment for the production of metal barrels and Steel Drums.

8,Cooling water :120 L/min  0.3Mpa  ≤23℃±2℃

9,Steel sheet precision:  Length ±0.5 mm  /diagonal line±1.0 mm

The Principle of Seam Welder:

It belongs to the scope of resistance welding: When the work pieces are assembled, and the pressure is applied onto it through the electrodes, and electric current flows through the overlapping contact surfaces and adjacent areas of the steel plates to generate resistance heat, thereby forming a series of overlapping nuggets to obtain airtightness Of welds.

The method adopted by this Three Phase Welder is rolling welding seam, the electrode is cylindrical roller, the width of it is larger than the overlapped part of the steel plate in order to control the thickness of the joint, and the larger electrode pressure and continuous current are applied during welding.

In order to make assure of the steady quality of weld,The longitudinal seam of the metal barrel and drum with a diameter of 516mm (cone barrel) to 571.5mm can be completed under the control of parameters such as electrode pressure, welding current, welding time, …etc.

The process of this Steel Drum Welder:

manually place the cut sheets on the rolling conveyor frame (also can be connected with the uncoiling leveling and blanking machine), and automatically transport them to the automatic slitting machine. After trimming, the sheets enter the automatic coil Round, no need for spot welding, that is, butt weld seam, take advantage of the red melting state of the steel plate, automatically roll the weld seam, automatically cut the tongue, and automatically discharge the material.

Efficiency: about 10 pcs/min.

Suitable Diameter: 516, 560, 571.5.

Parameter for Steel Drum Seam Welder

Automatic Feeding

After uncoiling and leveling, cut into standard specifications of barrel plates, stack them neatly on the rack to be loaded (the rack can be set up and down according to the number of steel plates), and then transport the plates to the slitting through a vacuum suction cup. Trimming and rolling mechanism. The conveyor line has a steel plate divider to ensure the separation of the front end of the plate, and an ultrasonic single-sheet detection device. If there are more than two steel plates, it will automatically alarm and stop.

Slitting and Trimming

The slitting machine adopts a circular knife shearing mechanism, online trimming and cutting, synchronized with the conveyor line. The trimming accuracy can reach 0.02mm, the cutting speed is 32mm/min, and the width is conventionally 1.0m, which can be customized. The thickness of the cut sheet is less than 1.5mm.

Automatic Adjustment of Roll Diameter

The winding part is composed of three pressure rollers, a guide roller fixing device and an adjustment mechanism. The plate material is fed through three rollers into a circular barrel shape, and the guide roller can reduce the straight edge of the front end, making the barrel more round and more beautiful.
