the sheet material is cut into the sheet material with the preset size and the coating gaps at two sides by the sheet material cutting machine, the sheet material is rolled into a circle by the circle forming machine, and the circular can body is welded by the seam welding machine.
102. Coating and drying the round can body;
the coating and leaving space inside the round can body is coated by a powder coating machine, the coating and leaving space outside the round can body is coated by a liquid coating machine, and finally the inner and outer coating parts are cured by a dryer to prevent the coating and leaving space of the can body from rusting.
103. Forming a round can body by expanding a cone to form a conical can with a large upper part and a small lower part;
it should be noted that the circular can body is expanded into a conical can with a large upper part and a small lower part by an expanding cone forming die.
104. The weld of the conical can is fixed to a preset position.
It should be noted that the weld joint is fixed at a designated position by a seam measuring device, so that the weld joint is fixed at the short side of the final product.
105. Expanding the conical can into a trapezoidal can by using a square expansion die;
in the molding process, the upper end and the lower end of the long edge are not straight lines but are arc lines slightly arched upwards due to the shape characteristics of the trapezoidal tank.
106. Pressing a vertical reinforcing rib on the long side of the trapezoidal tank;
in order to increase the strength of the can body, several vertical reinforcing ribs are pressed on the long side of the trapezoidal can by the body printing device. The reinforcing ribs are arranged to achieve the strength required by the use of the can body by using thinner materials, so that the material cost is reduced.
107. Expanding the diameter of the upper opening of the trapezoidal tank, flanging and trimming;
in order to avoid the lid surface residue after the full-open lid scribed line is opened, the upper opening of the trapezoidal tank is expanded to form a step larger than the existing trapezoid, so that the whole content can be poured out after the easy-open lid matched with the full-open lid is opened.
And flanging the trapezoidal tank after expanding the diameter up and down by using a flanging device to meet the requirement of tank sealing.
The trapezoidal tank can generate an outward arched arc in the process of expanding the square, so that the size deviation of the flanged long and short edges after flanging is large, and the quality problem sometimes occurs during tank sealing, so that the upper flange needs to be corrected to a proper size through the trimming device, the problem of size fluctuation after tank sealing caused by size fluctuation of the upper flange during batch production is solved, and the requirement of long-term stable production of a production line is met.
108. The upper opening of the trapezoidal can is sealed with the full-opening easy-open cover to form the full-opening easy-open cover trapezoidal can.
