Technical Process of Metal Barrel Production Line

This lecture focuses on the steel drum production line process , ie the process method of organization , process design has a direct impact on the production line automation , productivity and labor intensity .
First, the production process of steel drums
Below is a common steel drums production line process .

Common domestic steel drums production process diagram
To 200 liters closed steel drums , for example, the process of its manufacture process shown in Figure 3-1 . The process of drums with other similar, due to the materials used , the devices are different, there are differences in the process .
Flowchart includes both flat steel as raw steel drums production process , also includes a coil steel drums production process as raw materials , but also includes the use of semi-automatic seam welding process with the use of automatic seam welding process, but also includes the cleaning of the inner spray phosphating process .
Production requires the use of steel drums using coil uncoiling , leveling , cutting length of the process , which is currently the most advanced cutting production process. For the use of flat material production enterprise, " coil uncoiling leveling cutting " process just cutting this one .
Production of semi-automatic welding seam barrel body , the need for milling, rolling , welding position, seam welding several steps ; while using automatic seam welder , these processes are synthesized as seam welding, which dashed portion processes.
The top and bottom of the barrel barrel body cleaning phosphating process actually includes degreasing, cleaning , descaling , cleaning , phosphating , drying several steps , which is a washing line . For different companies, different user requirements , a portion or all of which can be omitted .
Inner coating drying process includes inner barrel body painted , inside bottom of the barrel roof coating, coating drying several processes , in some companies this is a production line. The figure shows the position within the coating drying process is closed steel drums coating process , for the opening drums , the current can be coated inside with the bottom of the barrel and the barrel body after sealing bead coated simultaneously.
Spiro ring and plug the production process , in fact, G2 and G3 / 4 of the closure is slightly different, in the G3 / 4 screw closure ring and plug the actual production, respectively, plus the required secondary and fine drawing entire two links.
Second, the unwinding cutting production line
Commonly used cutting production line process begins with the following:
1 , uncoiling → ​​shearing machine leveling → ​​Tablet → cutting → ​​stacking storage .
2 , uncoiling leveling → ​​→ forming → stacking stamping blanking → ​​storage . In order to save raw materials, can be stamped in the top end of the barrel blanking molding process for dislocation double punch punching . As shown below. Using two open- placed punch staggered opposite , can greatly improve production efficiency and material utilization.
The barrel roof material, you can also use the following production -line production : uncoiling leveling → ​​→ → bunghole punching punching forming spirals locking flange → → → storage preroll glue .
For bucket underneath material, can be applied to the following production -line production : uncoiling leveling → ​​→ → blanking forming preroll glue → storage .
Uncoiling leveling cutting with the top end of the barrel shaped locking screw chart , pre-roll gluing various processes combined into automated production lines , not only can greatly improve production efficiency, improve product quality , but also reduce labor and labor intensity .

Bottom of the barrel top dislocation punching nesting methods
3 , uncoiling leveling → ​​→ round knife cutting → ​​stacking vertical and horizontal shear → storage .
Third, the barrel top and bottom lines
1 , semi-automatic production line
Cutting → ​​forming → ​​Punching Blanking flange ( big mouth ) → punching flange ( small mouth ) → screw ring lock ( big mouth ) → screw ring lock ( small mouth ) → preroll glue .
2 , automatic production line
Uncoiling leveling → ​​→ → Punching Forming Blanking flange ( size of the mouth at the same time ) → spiro ring lock fitted ( size mouth simultaneously ) → preroll glue .
Fourth, the barrel body shaping production line
Common barrel body shaping production line process are the following
1, single head semi-automatic production line
Rolling Spot → → → sided flange seam welding flange → → unilateral unilateral unilateral pressure ripple voltage ripple → → → unilateral unilateral bulging tendons bulging tendons → → single head single head sealing sealing .
2 , double horizontal semi-automatic production line
Rolling seam welding → ​​→ → welding flange → bulging → ​​Beading → ​​sealing .
Rolling seam welding → ​​→ → bulging → ​​flanging Beading → ​​sealing .
3 , vertical automatic production line
Seam welding flange → → → → sealing bulging barrel → turn back .
Five , paint drying production line
1 , semi-automatic production line
Hand rub barrel → Painting ( manual air , static electricity or high-pressure airless spray ) → drying → manual screen printing or stencil printing .
2 , automatic production line

Surface cleaning production line → automatic painting production line ( inside painted , coated , two-color ) → drying production line ( drying and drying ) → automatic screen printing or thermal transfer .
