Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, and provides that a kind of processing technology is simple, the manufacture method of easy operating, rotary pressing pot that efficient is high.The conjugation in the bottom of a pan of the rotary pressing pot that the present invention makes is good, the phenomenon at the end can not occur taking off.
For this reason, the present invention adopts following technical scheme:
The manufacture method of rotary pressing pot of the present invention may further comprise the steps:
1) blanking: plate is made the disk material by punching press;
2) prestretched: the disk material that step 1) makes is made the stretching stock by the punching stretch forming mode;
3) spinning: the stretching stock is placed on the spinning mould, be processed into the pan embryo spare that the bottom of a pan is thick with the pot oral area, pot body sidewall approaches through spinning machine;
4) car mouth: the pot embryo oral area that spinning is good carries out smooth;
5) the multiple end: the pot embryo that turning is good is colded pressing at the multiple end on machine of the multiple end, or the multiple end of hot pressing is carried out in the heating back on friction press;
6) sandblast: the pot embryo that step 5) is obtained is filled in the anchor clamps of sand-blasting machine and carries out blasting treatment;
7) hardening oxidation is handled: the pot embryo is carried out hardening oxidation handle, promptly get required rotary pressing pot.
Above-mentioned steps 7) also be provided with spray treatment technology after, the pot embryo that is about to obtain carries out spraying inside and outside to be handled, or spray treatment gets final product in only need carrying out.
Above-mentioned steps 3) carry out spinning before, also be provided with to improving the plasticity of material, improve spinning speed and the technology that material is carried out preheating that is provided with, the stock that is about to stretch is done spinning after being heated to uniform temperature again.
Above-mentioned steps 1) be that coiled strip is made required disk material by blanking punched mode.
Above-mentioned steps 5) adopt at the multiple end of following form: it is compound to place pot embryo outer bottom to carry out high pressure by forcing press or hydraulic press iron plate.
Above-mentioned high pressure is 1000T-2000T.
Above-mentioned steps 5) adopt at the multiple end of following form: iron plate is placed a pot embryo outer bottom, and earlier by high-frequency heating or continuous tunnel furnace heat treated, it is compound to be placed on the enterprising horizontal high voltage of friction press again.
Above-mentioned high-frequency heating or continuous tunnel furnace heat treated make pot embryo temperature between 200 ℃-600 ℃, and above-mentioned high pressure is 1000T-2000T.
The present invention has following beneficial effect: with the pot that method of the present invention can make the bottom of a pan and the pot oral area is thick, pot body sidewall is thin, the preheating step among the present invention can effectively improve material plasticity, improves spinning speed.The present invention's conjugation and concentricity when the multiple end is better than prior art.Technology of the present invention is simple, easy operating, efficient are higher, and the conjugation in the bottom of a pan of the rotary pressing pot that makes with the present invention is good, the phenomenon that the end can not occur taking off.
The specific embodiment
Embodiment 1:
The manufacture method of rotary pressing pot of the present invention may further comprise the steps:
1) blanking: the disk material of coiled strip being made a certain size by blanking punched mode;
2) prestretched: tablet is made the stretching stock by the punching stretch forming mode;
3) preheating: be to improve the plasticity of material, improve spinning speed, do spinning again after the stretching stock can being heated to uniform temperature;
4) spinning: the stretching stock is placed on the spinning mould, be processed into the pan embryo spare that the bottom of a pan is thick with the pot oral area, pot body sidewall approaches through spinning machine;
5) car mouth: the pot embryo oral area that spinning is good carries out smooth;
6) the multiple end: it is compound to place pot embryo outer bottom to carry out high pressure by forcing press or hydraulic press iron plate, and high pressure is 1000T-2000T;
7) sandblast: the pot embryo that step 6) is obtained is filled in the anchor clamps of sand-blasting machine and carries out blasting treatment;
8) hardening oxidation is handled: the pot embryo is carried out hardening oxidation handle;
9) spray treatment: the pot embryo that will obtain carries out spraying inside and outside to be handled, and spraying gets final product in also or only need carrying out, for the pot type that need not to spray then this step can omit.
Embodiment 2:
The manufacture method of rotary pressing pot of the present invention may further comprise the steps:
1) blanking: the disk material of coiled strip being made a certain size by blanking punched mode;
2) prestretched: tablet is made the stretching stock by the punching stretch forming mode;
3) preheating: be to improve the plasticity of material, improve spinning speed, do spinning again after the stretching stock can being heated to uniform temperature;
4) spinning: the stretching stock is placed on the spinning mould, be processed into the pan embryo spare that the bottom of a pan is thick with the pot oral area, pot body sidewall approaches through spinning machine;
5) car mouth: the pot embryo oral area that spinning is good carries out smooth;
6) the multiple end: iron plate is placed a pot embryo outer bottom, by high-frequency heating or continuous tunnel furnace heat treated, make pot embryo temperature between 200 ℃-600 ℃ earlier, it is compound to be placed on the enterprising horizontal high voltage of friction press again, and high pressure is 800T-2000T;
7) sandblast: the pot embryo that step 6) is obtained is filled in the anchor clamps of sand-blasting machine and carries out blasting treatment;
8) hardening oxidation is handled: the pot embryo is carried out hardening oxidation handle;
9) spray treatment: the pot embryo that will obtain carries out spraying inside and outside to be handled, and spraying gets final product in also or only need carrying out, for the pot type that need not to spray then this step can omit.
