Problems solved by technology

[0003] However, the following problems exist in the above process: the annealing process is difficult to control, the annealing is not enough, and it is easy to be damaged during the expansion process.
The bulging process determines that the arc radius at the bottom of the billet will be relatively large, thus affecting the aesthetics of the appearance

Embodiment 1

[0016] A process for making an enamel cup blank, comprising the steps of:

[0017] 1) Cut the steel plate into circular steel sheets;

[0018] 2) Stretch the circular steel sheet into a cylindrical billet;

[0019] 3) Stretch the cylindrical billet again;

[0020] 4) Digitally shrink the cylindrical steel billet that has been pulled up again, and form a circular truncated steel billet;

[0021] 5) Trim the edge of the conical billet;

[0022] 6) Flanging the truncated round billet after edge trimming;

[0023] 7) Weld the truncated round steel billet with the handle to form the enamel cup body;

[0024] 8) The truncated steel billet welded with the handle will be inspected, and if it is qualified, it will be put into storage.

[0025] The enamel cup billet manufacturing process provided by this embodiment cancels the annealing process, solves all the problems caused by annealing, and changes the expansion type to the necking process, which not only reduces damage, but als...

Abstract

The invention discloses an enameled cup billet making process, which comprises the following steps of cutting a steel plate into a circular steel disc, stretching the circular steel disc to form a cylindrical billet steel, and stretching again; digitally necking the re-stretched cylindrical billet steel, and forming a circular truncated cone billet steel; trimming the circular truncated cone billet steel, and flanging; welding the flanged circular truncated cone billet steel with a handle, and forming an enameled cup body; checking out and putting in storage. According to the enameled cup billet making process, all problems caused by annealing are solved, and an expanding process is replaced with a necking process, so that the damage is reduced, meanwhile, the arc-shaped radius of the bottom part of balled iron can be smaller, and the appearance is more attractive.

Description

technical field [0001] The invention relates to a blank-making process, in particular to an enamel cup blank-making process. Background technique [0002] The currently used enamel cup blank making process mainly includes the following steps: 1. Cut the steel plate into circular steel sheets; 2. Stretch the circular steel sheets into cylindrical billets; 3. Stretch the cylindrical billet again; 4. Trimming the cylindrical steel billet after pulling up again; 5. Flanging the cylindrical billet after trimming; 6. Annealing the cylindrical billet after flanging; 7. Flanging the cylindrical billet after annealing 8. Bulge the truncated steel billet into a conical billet; 9. Weld the re-expanded conical billet with the handle to form an enamel cup blank; 10. After welding the handle The truncated steel billet is inspected, and if it is qualified, it will be put into storage. [0003] However, the following problems exist in the above process: the annealing process is difficult ...
