Punching, Stretching
According to the specifications of the workpiece, punch the workpieces of corresponding specifications;
After the workpieceis punched, the upper and lower bottle bodies are stretched (automatic stretching is adopted to reduce the unsafe hidden dangers caused by manual operation); (according to needs, the upper and lower bottles are equipped with a set of stretching machines for automatic punching , Automatic trimming, automatic joggling)

Welding and pressure test equipment
After the moisture is dried, it is connected to a flat conveying line to welding.
After the half-bottle body is assembled, it enters the welding process.
After the bottle body is welded, it will automatically flow to the chain conveyor line behind the welding machine, and then be transported to the pressure test conveyor line after the automatic grinding and welding machine.
After the pressure test is completed, proceed to the next process, moisture drying and
powder spraying
The heating of the drying tunnel adopts the hot air circulation method. Its advantage is
that the temperature in the drying tunnel is uniform, and the temperature difference between the middle and the lower three points
along the cross section of the track is less than ±5ºC.
The heating chamber is arranged in the lower part of the box. The hot air blower is used for circulation, and the circulation
method adopts the downward air supply and the downward return air mode, which eliminates the upper return air and external return air ducts, and reduces the heat loss.
