Technical field
The present invention relates to casting technology field, particularly relate to a kind of integrated leaf dish and manufacture method.
Background technique
In the prior art, the reflux blade of centrifugal compressor (blower) is by welding and be fixed on the leaf disk chassis with bolt, and wherein, reflux blade is to pass through blanking, hot-formingly process through the operation of necessity again with common slab; And the leaf disk chassis is to adopt the wooden model casting to form, and material need be processed for casting carbon steel, the surface that reinstalls the stream blade after the casting.
The shortcoming of prior art is that operation is long, cost is high, and efficient is low, and main cause is:
Need the blade profile pressing mold when producing reflux blade, stock's mould occupied ground is larger, and little repeat usage is low in batches, causes the frock cost very high.
Reflux blade adopts the blanking of Q235 slab, needs after the blanking to heat again die mould, needs Miniature oil press and small-sized box type stove.
Need to the going up planer into and out of air port costa shape and dig by designing shape and mill of reflux blade behind the die mould.Need planer.
The surface of leaf disk chassis solder reflow blade need to be gone up large vertical lathe and be processed, to guarantee the smooth and smooth of surface.Because adopting leaf disk chassis air spots, the machining allowance of wooden model casting puts all greatlyr.
Process rear reflux blade and weld with the leaf disk chassis, be designed with 18 reflux blades on the general leaf disk chassis, the processing plane amount of deformation reaches more than the 5mm sometimes after the welding.
The weld seam of reflux blade and leaf disk chassis adopts intermittent welding, air-flow by the time can produce new air resistance loss.
Summary of the invention
The technical problem that (one) will solve
The invention provides a kind of integrated leaf dish and manufacture method, be welded on and make on the leaf disk chassis that leaf dish operation is long, cost is high in order to solve in the prior art reflux blade, and inefficient problem.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 2, the integrated leaf disc manufacturing method in the embodiment of the invention comprises:
S1, with paraffin or the bonding one-tenth of foam and integrated leaf dish 1 size, integrated leaf dish model that shape is identical, this integrated leaf dish model is reflux blade model and leaf disk chassis model integration structure;
In the prior art, when reflux blade 2 is welded on the leaf disk chassis 3, the jointing place of reflux blade 2 and leaf disk chassis 3 is the right angle, and the amount of deformation during owing to welding is difficult to control, cause whole runner unsmooth, produce extra air resistance loss, cause the Efficiency Decreasing of centrifugal compressor and blower unit.
Preferably have 45 ° of casting inclined-planes in the present embodiment in the jointing place, right angle of reflux blade model and leaf disk chassis model, so that runner 4 natures, the circulation of gas in runner 4 is natural and tripping, reduces the air current flow loss, improves the efficient of centrifugal compressor and blower unit.Simultaneously can also prevent from cooling procedure, producing stress cracking, the making of convenient integrated leaf dish model.
S2, by casting integratedization of lost-foam casting method leaf dish 1.
Lost foam casting process is to brush refractory paint and oven dry outside the integrated leaf dish model that step S1 makes, be embedded in vibration molding in the dried silica sand, under negative pressure, pour into a mould, make the model gasification, liquid metal occupies modal position, solidify the rear novel casting method that forms gradually of cooling, comprise the pressure lost foam casting, founding casing with vacuum, vibration disappearance mould foundry etc., select the founding casing with vacuum method to come casting integratedization leaf dish 1 in the present embodiment, because the molding sand of vacuum casting does not add other materials in forming process, can reuse, the ashes of evaporative pattern in melt process are taken away by the vacuum pump negative pressure, separated by dust removal apparatus, the waste that produces in the whole casting process is few, and environmental pollution is little.
Integrated leaf dish 1 runner 4 of preferably casting by lost-foam casting method in the present embodiment does not stay machining allowance, once-through, omitted blanking when producing reflux blade 2, hot-forming, dig inlets and putlets of ventilation costa and the operations such as welding prelocalization line, welding, the restive problem of amount of deformation when having avoided welding of milling.
Shown in Fig. 1 a, 1b, 1c and 1d, integrated leaf dish 1 by the lost-foam casting method casting comprises reflux blade 2 and leaf disk chassis 3, wherein, reflux blade 2 and leaf disk chassis 3 are integrated, preferably have 45 ° of chamferings in the jointing place, right angle of reflux blade 2 and leaf disk chassis 3, so that runner 4 natures, the flow losses of air-flow have been reduced, improved the efficient of centrifugal compressor and blower unit, and these 45 ° of chamferings are by the moulding of integrated leaf dish model one-step casting, runner 4 does not stay machining allowance, saves material, reduces production costs.
As can be seen from the above embodiments, integrated leaf disc manufacturing method provided by the present invention is by casting integratedization of lost-foam casting method leaf dish, the integrated leaf dish runner of casting does not stay machining allowance, the nature moulding has significantly reduced manufacturing procedure, and has reduced cost of production, and jointing place, the right angle shape chamfering at 45 ° of backflow leaf dish and leaf disk chassis, so that runner is smooth, can not produce extra air resistance loss, improved the efficient of unit.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
