[0004] The purpose of the present invention is to provide a forming method for the production of pop can lids, by increasing the distance between the ring head and the pop can lids, to solve the problem in the prior art that is easy to be riveted when riveting. The tab head is too close to the can lid itself, or directly in close contact
When drinking canned beverages, it is laborious to open the ring head manually, and it is easy to scratch your fingers

Embodiment 1
[0032] A molding method for producing a tank can cover, including the following steps:
[0033] S1, the impreated wafer: mounts the coil of the aluminum sheet to the upper rack of the high-speed punch, using high-speed punch and high speed punch molds; high-speed punching in the system, the improving frequency is maintained 120-150 times per minute;
[0034] S2, Folding Process: Stack the wafer material in step S1 on the wafer feed carrier, and the pressure-derived edge is performed by the press. At the same time, there is also a concave rolled projection, pressed. The dent is located on the upper surface of the wafer; the folded edge depth is 2.0-2.5 mm, and the shape of the grooved concave is disposed as an arc-shaped structure, and the depth of the dent is set to 0.5 mm;
[0035] S3, encryption seal: The cover circle after folding the step S2 is completed, and the sealing strip mentioned in the cover of the cover is accurately added to the roller of the cover; the sealing strip...
Embodiment 2
[0046] A molding method for producing a tank can cover, including the following steps:
[0047] S1, the impulsive wafer: mount the wire of the steel sheet to the upper rack of the high-speed punch, using high-speed punch and high-speed punch molds, and the high-speed punch is in the system, the improving frequency is Minutes 220-260 times;
[0048] S2, Folding Process: Stack the wafer material in step S1 on the wafer feed carrier, and the pressure-derived edge is performed by the press. At the same time, there is also a concave rolled projection, pressed. The dent is located on the upper surface of the wafer; the folded edge depth is 1.5-2.0 mm, and the shape of its pressed concave is disposed as an arc-shaped structure, and the depth of the dent is set to 0.3 mm;
[0049] S3, encryption seal: The cover circle after folding the step S2 is completed, and the sealing strip mentioned in the cover of the cover is accurately added to the roller of the cover; the sealing strip mentioned...

Abstract
The invention discloses a forming method for the production of pop can lids, which comprises the following steps: using a high-speed punchingmachine and a high-speed punching die to punch discs; At the same time, there is also a dent pressing protrusion on the calendering and folding die, and the pressed dent is located on the upper surface of the disc; the aluminum sheet or steel sheet strip is placed on a press with a punching die to punch and pull the ring Hole operation; use a bending mold to push out one end of the ring head and bend it; curl the ring part with a bending structure; load the ring on the cover by riveting; this Invented to press a dent in the shape of an arc on the upper surface of the can lid, this dent can increase the distance between the tab head and the can lid; pre-bend the tab before loading, further increase the distance between the tab and the can The distance between the covers is convenient for the lifting operation of the pull ring, which saves manpower and prevents scratches during use.
Description
Technical field [0001] The invention belongs to the field of production technology of the tank canister, and is specifically related to the molding method for the production of a tank canile. Background technique [0002] The tank can be a common beverage container, which causing a can body through an aluminum or steel material, with a can cover with a pull ring, can directly pass the tank to tear a mouth directly through the pull ring. Then drink a drink. Due to its low manufacturing cost, simple manufacturing process, it can be loved by the vast enthusiasts. And the material of the easy-pull can can be recovered, and due to the large number of easy-to-pull, there is approximately 10 billion plus cans. [0003] The existing puls can be produced separately in the production of the cans and can caps in the production, and then the sealed press will be made when the beverage is sealed. The existing production process of the existing tank can includes: shock wafer → folding processi...
