Abstract
The present invention provides technology for forming fluid coupling pump impellers and turbines. Blank materials of a pump impeller casing, a turbine casing, pump impeller blades and turbine blades are cut by a steel plate; the outlines of the blank materials of the pump impeller casing and the turbine casing are carried out with turning circle finishing; the blade roots of the blank materials of the pump impeller blades and turbine blades are flanged; the shape of the pump impeller casing and the turbine casing are punched by a mould, and the preweld treatment is carried out; the formed pump impeller casing is welded with the pump impeller blades, the turbine casing and the turbine blades. Pump impellers and turbines formed by the technology of the present invention have the advantages of no casting flaw, preferable flow passage smoothness, high operating stability and high reliability. The energy consumption is low during operation.
Description
The present invention relates to the plant equipment processing technology of components, specifically fluid-flywheel clutch pump impeller, turbine contour machining procedure.
In the prior art, the pump impeller of fluid-flywheel clutch and turbine all are to use the aluminium alloy casting moulding.Pump impeller that is gone out by aluminium alloy casting and turbine have casting flaws such as casting shrinking hole, slag inclusion, runner be coarse, leakage of oil when casting flaw can make the part strength reduction and easily cause coupler work, also exist post-production and balancing workload big by the pump impeller of aluminium alloy casting moulding and turbine, the deficiency that energy consumption is high, and the inside crystalline phase tissue of pump impeller and turbine is difficult to control.In addition, the nonferrous materials price is expensive, and product cost is higher.
At the deficiencies in the prior art, the object of the present invention is to provide a kind of fluid-flywheel clutch pump impeller, turbine contour machining procedure, there is not casting flaw by fluid-flywheel clutch pump impeller, the turbine of this technological forming, the work energy consumption is little.
For achieving the above object, fluid-flywheel clutch pump impeller provided by the invention, turbine contour machining procedure are: (1), cut out out pump impeller housing, turbine shroud, pump impeller blade, the used blank of turbo blade by steel plate; (2), pump impeller housing, turbine shroud blank profile are carried out the finishing of car circle; (3), the blade root position flanging of pump impeller blade, turbo blade blank; (4), stamp out the shape of pump impeller housing, turbine shroud, and make descale and handle by mould; (5), the pump impeller housing of moulding and pump impeller blade, turbine shroud and turbo blade welding fabrication.
By above process program as seen, adopt fluid-flywheel clutch pump impeller, the turbine of steel plate it by punch and weld not to have casting flaw, surface cleanness and runner fineness are better, therefore, and job stability, good reliability.Because used steel plate materials is more even, when the post-production balancing, to join dynamic balancing and statically balanced workload and reduce, the energy consumption of rotating during work is low.And, the fluid-flywheel clutch pump impeller of this technological forming, turbine, its low cost of manufacture, long service life.
Description of drawings:
Fig. 1, process chart of the present invention;
Fig. 2, by the structure chart of fluid-flywheel clutch pump impeller one embodiment of technological forming of the present invention;
Fig. 3, by the structure chart of fluid-flywheel clutch turbine one embodiment of technological forming of the present invention.
The present invention is further described below in conjunction with embodiment and accompanying drawing.
Determine pump impeller housing, turbine shroud, pump impeller blade, the used sheet material of turbo blade earlier, the materials of pump impeller housing, turbine shroud, pump impeller blade, turbo blade are 10
#Cold-rolled steel sheet.By shown in Figure 1, concrete process is:
Blanking-cut out out the blank of pump impeller housing, turbine shroud by Q11-6.3 type plate shearing machine is cut out out the blank of pump impeller blade, turbo blade by J23-16 type plate shearing machine;
The car circle finishing-blank of pump impeller housing, turbine shroud is carried out the finishing of car circle by the CA6150 lathe;
Pump impeller blade, turbo blade blank blade root portion crimp-crimp is implemented at the blade root position of the blank of pump impeller blade, turbo blade by YA41-40 type folding brake;
Mould die mould-by YB32-300 type hydraulic press is by the blank die mould of mould to revised pump impeller housing, turbine shroud, the shape of making pump impeller housing, turbine shroud;
Welding pre-treatment-pump impeller the housing after the moulding, turbine shroud are implemented descale and handled, concrete processing method are, and be surperficial with the emery cloth polishing on the C6150 lathe.
Welding fabrication-with the pump impeller housing of moulding and pump impeller blade welding, turbine shroud and turbo blade welding, be spot welding for the first time, equipment is the DN3-100 electric welding machine, be soldering for the second time, it is strong promptly to carry out soldering on the basis of spot welding, equipment is the LH2-100 vacuum brazing furnace, so far finish pump impeller, turbine moulding.
Other machining operations of pump impeller behind the technological forming of the present invention, turbine are identical with the machining operation of existing pump impeller with the aluminium alloy casting moulding, turbine.
As shown in Figure 2, pump impeller blade 1 is carried out crimp to the root of pump impeller blade 1 and can be increased the bonding area of the two by the crimp 2 and 3 welding of pump impeller housing of its root.After the pump impeller moulding, chamber shape end face 5 is carried out turning processing.After pump impeller processes itself and adpting flange 6, bearing block 7 are welded, on adpting flange 6, bore tap out hole 8, and anti-end face 4 is processed in turning.After finishing above-mentioned operation, adopt static balance method smoothing weighing apparatus, join the weldering balance weight.Because the used sheet material of pump impeller is more even, the balance weight of joining weldering on the pump impeller is less, and the rotation energy consumption during work is less.
As shown in Figure 3, turbo blade 9 is by the crimp 10 and 11 welding of pump impeller housing of its root.After the turbine moulding, diligent mouthful 12 of location and the chamber shape end face 13 on it processed in turning.Then turbine and output shaft 15 are welded together, get out installing technological hole 14, and be benchmark, turning processing cavity shape end face 13 and edge face 16 with output shaft 15.Equally, finish above-mentioned processing after, integrally welded turbine and output shaft are smoothed weighing apparatus, are joined the weldering balance weight.
