The specific embodiment
Below with reference to above-mentioned accompanying drawing and with primary and secondary double flute model is 28211 to be that embodiment is described in further detail integral drawing technique of the present invention again, and its technical process is as follows:
(1) blanking: with the stainless steel trade mark is that SUS304, specification are that the coiled strip of 1 * 1219 * C is sent into plate shearing machine and cut into the required development size of tank (Fig. 1), is material-saving, adopts in pairs and shears;
(2) shear angle: the slab after the blanking is sent into plate shearing machine, carry out four jiaos of excess stocks and shear (Fig. 2), to prevent down the wrinkling in the road drawing process;
(3) stretch for the first time: the slab behind the shear angle is sent into the 630T hydraulic press, for the material that stops indivedual positions flows, prevent the drawing crack phenomenon, must be in advance on the first time stretching die reasonable Arrangement stretching muscle 3, so that stop this place's material to flow, avoid material by drawing crack, carry out double flute then and stretch for the first time (Fig. 3-4), at this moment vat 1 depth H
1=180mm, sulculus 2 depth H
2=150mm.
(4) cut the limit: the cell body after will stretching for the first time cuts off the both sides excess stock (Fig. 5) that is provided with stretching muscle 3 on cutter by designing requirement;
(5) cleaning treatment: artificial cleaning workpiece surface and oil contaminant, in case annealing back product surface forms the spot that can't remove;
(6) annealing in process: when stretching for the second time, reach the projected depth requirement smoothly in order to make tank, workpiece must be handled through bright annealing, so that material softening is prepared for stretching for the second time, annealing is carried out in bright annealing furnace, the control annealing temperature is 1160 ℃, and annealing heat time heating time is 30min;
(7) stretch for the second time: the stainless steel trough after will annealing carries out the drawing and forming second time in the second time on stretching die and 600/350 hydraulic press, this moment, frame 4 and big or small cell body 1,2 were pulled out fully, vat 1 dark H3=200mm, sulculus 2 dark 170mm (not shown), when vat and sulculus cell body are measure-alike, groove depth is also identical, when stretching for the second time, frame 4 materials do not enter cell body substantially, the cell body degree of depth and fillet place need material to compensate by the attenuation of cell body internal material fully, belong to ironing processing, the 30-40% (Fig. 6-7) that its maximum attenuation amount is an origianl wall thickness;
(8) cut edge: for the second time the tank of drawing and forming on edger and 315 hydraulic presses by the wide dimensional requirement of tank four cinctures cut edge (Fig. 8);
(9) punching: on water falling hole perforating die and 100B hydraulic press, go out end water falling hole 5 (Fig. 9) in the groove;
(10) punching: on spillway hole perforating die and 315 hydraulic presses, go out sidewall spillway hole 6 (Figure 10-11);
(11) clean: the flume surface greasy dirt is manually cleaned;
(12) mark: print (Figure 12) at mark mould and enterprising mark 7 patterns of doing business of 63 hydraulic presses;
(13) welding reinforcement: spot welding reinforcement 8 around the frame at the tank back side, this operation is carried out (Figure 13) on 200 percussion welders, the setting of reinforcement 8 is determined on a case-by-case basis, be fixed on cabinet top for tank, must weld reinforcement, be convenient to fix, as be fixed on the cabinet below, can remove reinforcement from cabinet.
(14) surface treatment: this operation at first goes to institute jagged by artificial polishing; Then blasting treatment is placed on and carries out double-colored spray cell body on the automatic sand-blasting machine and inferior light sprays entirely; Bright afterwards electrolysis descale carries out spray treatment at last, gives cell body outer surface spraying noise reduction, anti-reverse osmosis water gas colloid, and polishing, sandblast, electrolysis descale, spraying are carried out in order;
(15) punching: on the hydraulic pressure puncher, tank frame 4 places are carried out leading installing hole 9 and soap lye installing hole 10 is processed (Figure 14);
So far, processing technology is all over, and finished product primary-secondary type disjunctor tank as shown in figure 15.
(16) last test package warehouse-in.
