Task of the present invention is finished like this, a kind of processing method of spray axial fan backwater cylindrical shell, and its process step is as follows:
A. spinning loose tool and spinning roller are got in backwater cylindrical shell specification requirement according to expectation ready;
B. backwater cylindrical shell size requirement according to expectation is to the plain plate blanking, and curls and be welded into revolving of a cylinder
The dabbing base;
C. the spinning fetal membrane is installed on the general mould of spinning machine;
D. the spinning blank is positioned in the spinning loose tool, and itself and spinning loose tool are fixed;
E. spinning roller is installed on the spinning dish axle of spinning machine;
F. drive spinning machine, the motion of spinning dish after being spun to half of back flow water pump on the spinning blank, changing into and revolving
Push back the groove plane of tank;
G. the spinning loose tool is unloaded from general mould together with the spinning blank, be installed to again after the tune on the general mould,
Be spun to second half of back flow water pump on the spinning blank, the other end with the spinning blank is spun to horn mouth again, unloads
Obtain the backwater cylindrical shell down.
Processing method of the present invention has that the spinning machine that can use the routine in the prior art carries out spinning, process procedure is few, work efficiency is high, can not waste material, advantage that fabricating cost is low.

Embodiment
Embodiment:
A. process what a mould as shown in Figure 2 according to the required large and small specification requirement of backwater cylindrical shell of spray axial fan, this mould is referred to as spinning loose tool 1, and is equipped with one by the spinning roller 17 of anticipating shown in Fig. 2;
B. according to the large and small specification requirement of the required backwater cylindrical shell of spray axial fan, calculate blanking figure, then by the flat material of thin type steel plate under the blanking figure size, and with its curl be welded into a length be L1, external diameter be Φ D identical with spinning loose tool 1 minimum diameter by spinning blank 18 shown in Figure 1;
C. by shown in Figure 2, spinning loose tool 1 is installed on the general mould 19 on the main shaft 6 of spinning machine 7, and around fixed with screw 2;
D. by shown in Figure 2, spinning blank 18 is positioned in the spinning fetal membrane 1, and the tension device 4 of two semicircles placed the position of spinning blank 18 inner chambers corresponding to D, and make tension device 4 expansions by regulating tensioner screw 5, spinning blank 18 is fixed on firmly the inner chamber of spinning loose tool 1.
E. by shown in Figure 2, spinning roller 17 is realized axial motion by axial oil cylinder 8 and piston rod 9, claims axial feed again or claims left and right motion; Realize radial motions by radial oil cylinders 13, claim radially feed again or claim the forward and back motion, comprehensive vertical, horizontal compound motion and finally realize being spun to the shape that meets the workpiece necessary requirement.Specifically: the end that spinning roller 17 is installed to the spinning dish axle 16 of spinning machine 7, spinning dish axle 16 is with 13 one-tenth 90 ° of radial oil cylinders and fix, radial oil cylinders 13 places on the radial oil cylinders fixed base 12 by radial oil cylinders guide rail 15, make spinning dish axle 16 in spinning loose tool 1, do radial displacement, because the piston rod 9 of axial oil cylinder 8 is installed on the radial oil cylinders fixed base 12, and be placed in again on the axial guidance 21 of oil cylinder support 14, spinning roller 17 can be done by left and right axial motion shown in Figure 2 with radial oil cylinders 8;
F. drive spinning machine 7, making main shaft 6 drive general mould 19, spinning loose tool 1 and spinning blank 18 rotates together, rotating speed is then decided on the workpiece diameter size, in such cases, mobile spinning roller 17 exists a material thick with spinning loose tool 1 forming surface gap, therefore, utilizes the relative movement that produces between spinning loose tool 1 and the spinning roller 17, can force spinning blank 18 to be shaped, promptly paste mould by the shape of spinning loose tool 1.Specifically: in running order following at spinning machine 7, effect by radial oil cylinders 13, spinning dish axle 16 is inwardly motion (feed) gradually, with spinning roller 17 gradually near the B of spinning blank 18, C oblique point F, spinning roller 17 is in the footpath, axial oil cylinder 13,8 effect continues along the track of the groove H wall of spinning loose tool 1 inside down, alternately compound motion backward, the C portion zone of spinning blank 18 is stretched, cause the groove internal chamber wall that diameter expands spinning loose tool 1 gradually to, so far make half that is spun on the spinning blank 18 by back flow water pump shown in Figure 4, change the spin slot plane again, then spinning roller 17 is withdrawed from, in the footpath, axial oil cylinder 13, under 8 the effect, make spinning roller 17 move to the B zone of spinning blank 18 through the F zone, again to the a-quadrant expanding spinning of spinning blank 18, to be reserved in past the turning up in a-quadrant of one section spinning blank 18 in spinning loose tool 1 outside by this, and form the flange edge 10 that connects usefulness is installed;
G. spinning loose tool 1 is unloaded from general mould 19 together with spinning blank 18, tune is after 180 ° of the conversion, spinning loose tool 1 is taken spinning blank 18 to be installed on the general mould 19 once again, and fix it by set screw 2 with aforementioned manner, footpath at spinning machine 7, axial oil cylinder 13, under 8 the effect, spinning roller 17 is moved in spinning blank 18 has been finished the C zone groove of processing, spinning roller 17 is outwards made aforesaid alternately compound motion along groove walls, when moving to the G zone or claiming the G point, promptly finished second half shaping by the back flow water pump in whole C zone shown in Figure 5, spinning roller 17 just moves to outside spinning along the D zone, to reserving when the E in spinning blank 18 outsides is regional, spinning roller 17 moves spinning E zone along the horn mouth edge nearly 45 ° hypotenuse of Y of spinning loose tool 1, make the E zone of spinning blank 18 identical, make an end of spinning blank 18 form horn mouth 11 by this with the horn mouth of spinning loose tool 1.Song Qi moves apart upper mold section by the set screw that is connected and fixed screw 3, upper mold section 2 of tensioner screw of illustrating among Fig. 35 and spinning loose tool 1 upper and lower half module, and the backwater cylindrical shell 20 by shown in Figure 6 after being shaped is taken off.
