Referring to Fig. 1 to Fig. 5, the canister processing technology includes the following steps：

Material preparation phase：

Sheet material is rolled by tubulation apparatus and is welded into tubing by step 1, tubulation.

Tubing is cut into two canisters by Pipe Cutting equipment and corresponded to by step 2, blanking according to actual production demand The workpiece 33 of length, as shown in Fig. 2, above-mentioned corresponding length be interpreted as include the required length of two canisters and after Continuous cutting surplus.

Step 3, smooth weld seam improve 33 table of workpiece using the commissure of idler wheel roll off workpiece 33 to flatten weld seam The flatness in face.

The swollen type stage：

The workpiece 33 of above-mentioned steps three is put into the lower die 2 of swollen pattern tool, so that the lower part of workpiece 33 is placed in by step 4 In lower impressions 20 and it is set in the outside of lower mold core 23, upper mold 1 is then closed, the top of workpiece 33 is made to be placed in upper impression 10 simultaneously It is set in the outside of upper mold core 13, to seal workpiece both ends.

Steam in swollen pattern tool is discharged, and ensures its leakproofness by step 5, and liquid is filled then to 33 inside of workpiece Body.

Step 6, molding apply pressure to the liquid of 33 inside of workpiece, workpiece 33 are made to occur to be plastically deformed in fitting respectively The side wall of die holder 12 and lower die holder 22, to process the shape adaptable with upper die holder 12 and 22 inner wall of lower die holder, wherein wrapping Include and process the bottle body of two canisters, be located at the middle part of workpiece 33 and bulge-structure 331 corresponding with the recess portion and Circle lug boss 335 corresponding with the technique cavity is processed on the position of respective protrusions structure 331, as shown in Figure 2.

Step 7, it is seperated, workpiece 33 is cut into two monomers 332 along the middle part of 33 length direction of workpiece, makes raised knot Structure 331 is divided into two flow-guiding mouths 336 connected respectively with corresponding monomer 332, and the lug boss 335 is split, To obtain two metal container structures；For example, when needing to process the identical kettle liner of two length, grown along workpiece 33 The center line for spending direction cuts workpiece 33, to obtain the identical monomer 332 of two length, as shown in Figure 2；When needing to process two When the different kettle liner of a length, the benchmark of cutting then exists with the center line of 33 length direction of above-mentioned workpiece vertical inclined It moves.As a kind of specific embodiment, before carrying out above-mentioned steps seven, first 33 end of workpiece after molding can be cut Mouth processing adjusts the length of workpiece 33 to adapt to the length needed for actual metal container.

Truing phase：

As shown in Fig. 2, one end that monomer 332 is equipped with to flow-guiding mouth 336 is defined as upper end, opposite one end is defined as down End.

The outside bending x degree in the upper end of each monomer 332 is formed bending part 333, the value model of the x by step 8, flanging It is trapped among between 60 to 120 degree, preferably 60 degree, 90 degree and 120 degree, as shown in Figures 2 and 3.

The extra part in 333 outer end of bending part is cut off, is such as schemed according to the actual standard requirement of product by step 9, deburring Shown in 2.

The outer end downward bending y degree of bending part 333 after excision redundance is formed flange 334 by step 10, turned welt, The value range of the y is between 60 to 120 degree, preferably 60 degree, 90 degree and 120 degree, as shown in Figure 2 and Figure 4.

Step 11, flat mouth, flange 334 described in inside bending make it fit in the lower end of the bending part 333, such as Fig. 2 Shown in Fig. 5.

In a kind of specific embodiment, the step of above-mentioned finishing stage, can be completed by stamping equipment.
