the blanking plate 62 is cut out, and the blanking plate 62 is a flat plate and includes a regular segment 621 and two irregular segments 622 integrally disposed at two ends of the regular segment 621. The regular segments 621 are rectangular and the two irregular segments 622 are symmetrically distributed along the central axis L of the regular segments 621. The regular segment 621 includes two parallel first and second

straight sides

6211 and 6212, and the two first and second

straight sides

6211 and 6212 are spaced apart. The outer contour of the irregular segment 622 includes a first side 6221, a second side 6222, a third side 6223 and a fourth side 6224 connected in series.

The fourth side 6224 has one end connected to the third side 6223 and the other end connected to the second straight side 6212 of the regular segment 621.

Half shell ring 611 is rolled along third edges 6223 of two irregular sections 622 in alignment and close manner, so that half shell ring 611 includes a cylindrical first unit 6115 and a half cone-shaped second unit 6116, and the central axis of first unit 6115 is perpendicular to the central axis of second unit 6116.

Specifically, when half shell ring 611 is obtained by roll forming of blanking plate 62, half shell ring 611 can be obtained by direct roll forming through a set of dies. Or the first unit 6115 can be rolled on a mold, and then the second unit 6116 can be rolled on another mold by a lifting appliance. The second unit 6116 can be rolled on one mold, and then the first unit 6115 can be rolled on another mold by hoisting through a lifting appliance.

Two half cylindrical sections 611 having the same height dimension are butt-welded to each other in such a manner as to be aligned along the axis to form a cylindrical section 61.

Specifically, the welding between shell ring 61 and shell ring 61 is also a circumferential weld, which is beneficial to mechanized welding.

In the embodiment, the material discharging plate is integrally wound and formed, the two prefabricated half shell sections are welded to form the shell section, and finally the shell sections are mutually spliced along the axial direction of the self shell shape to obtain the tank body. The two half shell ring sections are welded into a circumferential weld, and the weld between two adjacent shell ring sections is also a circumferential weld, so that the mechanical welding is facilitated, and the production efficiency of the tank body is improved.

Meanwhile, the forming mode of the half shell ring and the forming mode of the shell ring do not have the phenomenon that the effective space for loading materials in the tank body is reduced due to the increased plates when the cylindrical structure and the conical structure are spliced and welded, so that the effective volume in the tank body is increased. Because the inside of the shell ring is smooth, the materials can smoothly flow to the bottom of the shell ring, no dead angle for discharging exists, and the discharging is clean.

Two half shell sections 611 of shell section 61 in this embodiment have the same dimension in the axial direction.

In other embodiments, the axial dimensions of two half-shell sections 611 of shell section 61 may not be uniform. Illustratively, the rear-end shell ring in the first embodiment of the tank body, i.e. the shell ring at the left end in fig. 2, also includes two half shell rings, namely a left-side half shell ring and a right-side half shell ring, and the left-side half shell ring and the right-side half shell ring are different in size along the axial direction.

Second embodiment of the Shell Ring

Specifically, a blanking plate located in a plane is pressed to form a transition surface through pressing, so that the blanking plate is in a plurality of parts located in a plurality of planes, and then rolling forming is carried out. Wherein the transition surface is in a strip shape. After the blanking plate is wound into a half cylindrical section, the transition surface forms a intersecting line of the first unit and the second unit. The intersecting line is an intersecting line formed on the surface when two three-dimensional structures intersect. In this embodiment, the two three-dimensional structures refer to the first unit and the second unit, respectively, and therefore, the intersecting line refers to an intersecting line formed on the surface when the first unit and the second unit intersect with each other.

Referring to fig. 82, the blanking plate has substantially the same structure as the blanking plate of the first embodiment of the shell ring, except that the blanking plate of the present embodiment is first press-formed to obtain a transition surface, which can be shown by a dotted line in the figure.

Or the blanking plate can be a plate with uneven material thickness, and the material thickness of the drawing and stretching position of the blanking plate is larger than that of other positions, so that the local strength of the drawing and stretching position is improved, and the requirement on the overall strength can be met after the blanking plate is drawn and stretched. During concrete implementation, the blanking plate can be formed by mutually welding a plurality of plates with different thicknesses, and can also be integrally formed by adopting a special process, such as a 3D printing process and the like.

In this embodiment, in the method for forming a can body, before rolling the blanking plate, the method further includes the following steps:

a transition surface is pressed at the junction position of the first unit and the second unit.

And when the transition surface is pressed, welding a reinforcing plate at the inner side of the drawing and extending position of the blanking plate.

And then rolling and forming the half cylindrical section, and enabling the reinforcing plate to be positioned on the inner side of the half cylindrical section.

The remaining steps are the same as in the first embodiment of the shell ring.
