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
The present invention relates to a kind of blank-making technology, particularly relate to a kind of enamelled cup blank-making technology.
Background technology
The enamelled cup blank-making technology of current use mainly comprises the following steps: 1. steel plate is cut into circular steel disc; 2. circular steel disc is drawn into cylindric steel billet; 3. cylindric steel billet is stretched again; 4. the cylindric steel billet after again drawing high is carried out trimming; 5. the cylindric steel billet after trimming is done flange process; 6. the cylindric steel billet after flange is carried out annealing in process; 7. the cylindric steel billet after annealing in process is carried out swollen type and become round table-like steel billet; 8. swollen type is become round table-like steel billet swollen type again; 9. the round table-like steel billet after swollen type is again welded with handle and form enamelled cup base substrate, 10. the round table-like steel billet after welding with handle is tested, if qualified, put in storage.
And the following problem that above technique exists: annealing operation, is difficult to control, and annealing is not, easily damaged in swollen type process, annealed, in follow-up enamel firing process, easily occur the enamel surfaces defects such as bubble.Swollen type technique determines the arc radius located bottom steel billet can be larger, therefore have impact on the aesthetics of appearance and modeling.
Summary of the invention
The object of the present invention is to provide a kind of enamelled cup blank-making technology, have without the need to annealing in process and the little feature of the arc radius located bottom enamel base substrate cup.
In order to achieve the above object, technical scheme of the present invention is: a kind of enamelled cup blank-making technology, comprises the steps:
1) steel plate is cut into circular steel disc;
2) circular steel disc is drawn into cylindric steel billet;
3) cylindric steel billet is stretched again;
4) the cylindric steel billet after again drawing high is carried out digital reducing, and form round table-like steel billet;
5) round table-like steel billet is carried out trimming;
6) the round table-like steel billet after trimming is done flange process;
7) the round table-like steel billet after flange is welded with handle, and form enamelled cup base substrate;
8) the round table-like steel billet after welding with handle is tested, if qualified, put in storage.
The invention has the beneficial effects as follows: then the present invention is drawn into cylindric steel billet by first steel plate being cut into circular steel disc, and again stretches.Cylindric steel billet after again drawing high is carried out digital reducing, and forms round table-like steel billet.Round table-like steel billet is carried out trimming, then flange.Round table-like steel billet after flange is welded with handle, and forms enamelled cup base substrate.Be up to the standards and put in storage.Eliminate annealing operation, solve all problems because annealing produces, changing swollen type is necking down process, not only reduces breakage, and the arc radius simultaneously bottom baslled iron can be less, makes moulding more attractive in appearance.
Detailed description of the invention
Embodiment 1
A kind of enamelled cup blank-making technology, comprises the steps:
1) steel plate is cut into circular steel disc;
2) circular steel disc is drawn into cylindric steel billet;
3) cylindric steel billet is stretched again;
4) the cylindric steel billet after again drawing high is carried out digital reducing, and form round table-like steel billet;
5) round table-like steel billet is carried out trimming;
6) the round table-like steel billet after trimming is done flange process;
7) the round table-like steel billet after flange is welded with handle, and form enamelled cup base substrate;
8) the round table-like steel billet after welding with handle is tested, if qualified, put in storage.
A kind of enamelled cup blank-making technology that the present embodiment provides eliminates annealing operation, and solve all problems because annealing produces, changing swollen type is necking down process, not only reduces breakage, and the arc radius simultaneously bottom baslled iron can be less, makes moulding more attractive in appearance.
