The two first units 6115 are connected with each other and still have a cylindrical shape, and the two second units 6116 are connected with each other and have an inverted cone shape with a gradually reduced caliber from top to bottom. I.e., the large mouth ends of the half shells 611 are connected to each other. After the large opening ends are connected, the two openings are enclosed to form a circular hole, namely a discharging hole.

In this embodiment, the cross section of the lower portion of the shell ring 61 is circular, that is, the cross section of the shape enclosed by the second units 6115 of the two half shell rings 611 is circular. In other embodiments, the cross-section of the lower portion of the shell ring 61 may also be oblong, oval.

The half shell ring 611 can be directly formed by integrally winding a blanking plate 62.

Specifically, the blanking plate 62 is irregularly shaped and is formed by rolling in a plane.

The regular segment 621 includes two first and second straight sides 6211, 6212 that are parallel to each other, with the first and second straight sides 6211, 6212 being spaced apart. The outer contour of irregular segment 622 includes a first side 6221, a second side 6222, a third side 6223, and a fourth side 6224 that are connected in sequence. Wherein the first side 6221 is a straight side and extends integrally from the regularly segmented straight side 6211. The second side 6222 is in a circular arc shape, the concave surface of the second side 6222 faces the outside of the blanking plate 62, the convex surfaces of the second sides 6222 of the two irregular sections 622 are oppositely arranged, the third side 6223 is a straight side, and the intersection point of the extension line of the third side 6223 and the extension line of the first side 6221 is the center of the circle where the second side 6222 is located. Fourth side 6224 is arcuate with its convex surface facing first side 6221. Fourth side 6224 is connected at one end to third side 6223 and at the other end to second straight side 6212 of regular segment 621.

After the blanking plate 62 is wound into the half cylinder section 61, the first straight side 6211 and the second straight side 6212 are formed into two contour lines of the first unit 6115, and the two fourth sides 6224, the two third sides 6223, and the two second sides 6222 are formed into contour lines of the second unit 6116.

Preferably, the central angle of the second side 6222 is 90 degrees, i.e., the second side 6222 is one-quarter circular.

The present embodiment also provides a method for forming a can body, which is obtained by welding the shell ring 61 according to the present utility model, comprising the steps of:

the blanking plate 62 is cut out, and the blanking plate 62 is a flat plate and comprises a regular segment 621 and two irregular segments 622 which are respectively and integrally arranged at two ends of the regular segment 621. Regular segment 621 is rectangular and two irregular segments 622 are symmetrically distributed along the central axis L of regular segment 621. The regular segment 621 includes two first and second straight sides 6211, 6212 that are parallel to each other, with the first and second straight sides 6211, 6212 being spaced apart. The outer contour of irregular segment 622 includes a first side 6221, a second side 6222, a third side 6223, and a fourth side 6224 that are connected in sequence. Wherein the first side 6221 is a straight side and extends integrally from the regularly segmented straight side 6211. The second side 6222 is in a circular arc shape, the concave surface of the second side 6222 faces the outside of the blanking plate 62, the convex surfaces of the second sides 6222 of the two irregular sections 622 are oppositely arranged, the third side 6223 is a straight side, and the intersection point of the extension line of the third side 6223 and the extension line of the first side 6221 is the center of the circle where the second side 6222 is located. Fourth side 6224 is arcuate with its convex surface facing first side 6221. Fourth side 6224 is connected at one end to third side 6223 and at the other end to second straight side 6212 of regular segment 621.

The blanking plate 62 is rolled into a half cylinder 611 along the third sides 6223 of the two irregular sections 622 in an aligned and close manner, so that the half cylinder 611 comprises a cylindrical first unit 6115 and a half cone-shaped second unit 6116, and the central axis of the first unit 6115 is perpendicular to the central axis of the second unit 6116.

Specifically, when the blanking plate 62 is roll-formed to obtain the half-cylindrical section 611, the half-cylindrical section 611 may be directly roll-formed by a combination of dies. The first unit 6115 may be rolled on one mold, and then lifted on another mold by a lifting tool to roll the second unit 6116. The second unit 6116 may be rolled on one die, and then the first unit 6115 may be rolled on another die by lifting the second unit on the other die.

Two half-shells 611 of the same height dimension are butt welded to each other in an axis aligned manner to form a shell segment 61.

Specifically, the welding between the half cylinder ring 611 and the half cylinder ring 611 is a circumferential weld, which is beneficial to mechanical welding.

The multiple cylinder sections 61 are mutually assembled and welded to form a tank body for loading materials.

Specifically, the welding between the cylinder sections 61 and 61 is also circumferential welding, which is beneficial to mechanical welding.

In this embodiment, through the integrative coiling shaping of flitch, weld two prefabricated half shell ring each other and form the shell ring, splice shell ring each other along its self cylindric axial at last, can obtain the jar body. The welding between the two half cylinder sections is a girth joint, and the welding between the two adjacent cylinder sections is also a girth joint, so that the mechanized welding is facilitated, and the production efficiency of the tank body is improved.

Meanwhile, the forming mode of the half cylinder section and the forming mode of the cylinder section are free from the phenomenon that the effective space for loading materials in the tank body is reduced due to the added plates during splicing and welding of the cylindrical structure and the conical structure, so that the effective volume in the tank body is increased. Because the inside of the cylinder section is smooth, the material can smoothly flow to the bottom of the cylinder section, no unloading dead angle exists, and the unloading is cleaner.

The two half-shell rings 611 of the shell ring 61 in the present embodiment are identical in size in the axial direction.

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

Second embodiment of the cylindrical shell section

The difference between this embodiment and the first embodiment of the shell ring is that: the half cylinder section is formed by pressing a transition surface at the junction position of the first unit and the second unit before the blanking plate is wound and formed.

Specifically, a blanking plate positioned in a plane is pressed out of a transition surface by compression, so that the blanking plate presents a plurality of parts positioned in a plurality of planes, and then is rolled and formed. Wherein the transition surface is in a belt shape. After the blanking plate is wound into a half cylinder section, the transition surface forms an intersecting line of the first unit and the second unit. Intersecting lines refer to intersecting lines formed on the surface when two three-dimensional structures intersect. In this embodiment, the two-dimensional structures refer to the first unit and the second unit, respectively, and thus, the intersecting line refers to an intersecting line formed at the surface when the first unit and the second unit intersect.

Referring to fig. 82, the blanking plate has substantially the same structure as the blanking plate in the first embodiment of the shell ring, except that the blanking plate in this embodiment is first pressed to form a transition surface, and the transition surface may be shown by a dotted line in the figure.

In order to improve the local strength of the drawing position of the blanking plate, the blanking plate is generally a flat plate with uniform thickness, and the blanking plate further comprises a reinforcing plate arranged on the inner side of the drawing position of the blanking plate when the half cylinder section and the pressing transition surface are wound.

Or the blanking plate can also be a plate with uneven material thickness, and the material thickness of the drawing and extending position of the blanking plate is larger than that of other positions, so that the local strength of the drawing and extending position is improved, and the whole strength requirement can be met after the drawing and extending. In particular, the blanking plate can be formed by mutually splicing and 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, the method further includes the following steps before rolling the blanking plate:

When the transition surface is pressed, the method further comprises welding a reinforcing plate at the inner side of the drawing and extending position of the blanking plate.

And then rolling to form a half cylinder section, and positioning the reinforcing plate on the inner side of the half cylinder section.

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

By adopting the molding mode in the embodiment, the molding difficulty of the half cylinder section is further reduced.
