Description

The processing method of impellor mould of pressurizing unit compressor

Technical field:

The invention belongs to machining, casting technology field, be specifically related to a kind of processing method of impellor mould of pressurizing unit compressor.

Background technology:

The compressor impeller blank of general vehicle supercharger is to form by hot investment casting.Promptly utilize metal die to carry out multisteps such as sn-bi alloy, silicon rubber, gypsum, resin and turn over system technology suddenly, finally obtain the aluminum compressor impeller.Adopt this method to turn over the die process complexity, hand grinding often, manual intervention is big, precision of blades loss is also just big, and the process-cycle is longer.

Summary of the invention:

The present invention is just in order to solve the deficiency of above existing manufacturing technology, and proposes a kind of processing method of impellor mould of pressurizing unit compressor.

Technical scheme of the present invention is: a kind of processing method of impellor mould of pressurizing unit compressor, and its processing step is:

1. low melting material blank moulding: adopting fusing point is the diffusing sheet raw material of 47 °-70 ° low melting point pie, after the electric furnace heat fused, in vacuum drying oven, pour drum shape blank moulding frock into, treat half solidification and crystallization state, carry out artificial hammering, natural cooling forming;

2. roughing turning low melting material compressor impeller blank: the cylindrical blank of moulding is carried out roughing turning before five-shaft numerical control mills, promptly adopt the scroll chuck mode to locate, little cutting output, fast feeding processing technology are adopted in each zone cutting, and adding the man-hour cooling fluid can not pause;

3. use pro/engineer software, set up the compressor impeller threedimensional model; And model is amplified according to 3% ratio;

4. five-shaft numerical control programming, emulation, processing: with step 2. the compressor impeller blank clamping of roughing turning on the five-shaft numerical control machining center, with the compressor impeller threedimensional model of setting up, carry out the five-shaft numerical control programming, carry out machining simulation, millings such as low melting material gas compressor blade impeller blade, wheel hub, runner are carried out in correct back on the five-shaft numerical control machining center, machine the impeller material object that amplify for the 2.5%--3.5% ratio back, this compressor impeller custom is referred to as the mould formpiston;

5. record resin former, fusing low melting point compressor impeller formpiston: with the compressor impeller formpiston after the milling, size according to profile puts it in the columned frock, in vacuum drying oven, record the resin former, boiling water with 100 ℃ after 24 hours melts the low melting point impeller, and resin compressor impeller former completes;

6. record the silicon rubber formpiston: after silicon rubber is stirred, turn over system silicon rubber formpiston, and repair processing in defective place;

7. turn over system gypsum former: turn over the silicon rubber formpiston of system more than inciting somebody to action, carry out the system of turning over of gypsum former;

8. use gypsum former cast aluminum impeller shaped article.

Beneficial effect of the present invention: adopt this method in the booster industry, can obtain hot investment casting compressor impeller product fast, and cost is low, the precision height.

The specific embodiment:

Below most preferred embodiment of the present invention is described in detail, a kind of processing method of impellor mould of pressurizing unit compressor, its processing step is:

1. low melting material blank moulding: low melting material is the diffusing sheet of pie when buying, make earlier blank and fusing frock, adopt fusing point be 47 °-70 ° low melting material all can because melting temperature is high more, the digital control processing comprehensive mechanical performance is good more, and material price is also cheap more.Raw material are poured the moulding frock into through the electric furnace heat fused in vacuum drying oven, treat half solidification and crystallization state, carry out artificial hammering, increase the tight ness rating of material, produce casting flaw to prevent material internal.Cooling forming is amplified in the influence of shrinkage factor when considering hot investment casting by 2.5%--3.5% percentage.

2. roughing turning low melting material compressor impeller blank: the formpiston of moulding is carried out turning processing before five-shaft numerical control mills, male mold adopts the scroll chuck mode to locate, because low melting material intensity is low, little cutting output, fast feeding processing technology are adopted in each zone cutting, the little cutting output milling of multilayer, it is less to connect tool marks at blade surface, can obtain evenly allowance, for the fine finishining blade provides good machining condition, help to provide the stock-removing efficiency and the surface quality of following process; Fast feeding helps to improve working (machining) efficiency; Little cutting output, fast feeding simultaneously can reduce Tool in Cutting power greatly; Five-shaft numerical control processing can be selected different milling cutters for use according to technological requirement, because material melting point is lower, adding the man-hour cooling fluid can not pause.

3. use pro/engineer software, set up the compressor impeller threedimensional model; And model is amplified according to 3% ratio;

4. five-shaft numerical control programming, emulation, processing: with step 2. the compressor impeller blank clamping of roughing turning on the five-shaft numerical control machining center, with the compressor impeller threedimensional model of setting up, carry out the five-shaft numerical control programming, carry out machining simulation, after correct program is input in five machining center equipment, carries out millings such as low melting material gas compressor blade impeller blade, wheel hub, runner.Its machining process route is: fluting roughing, wheel hub processing, three operations of blade fine finishining are carried out.When carrying out Impeller Machining, divide equally 360 degree, carry out the fluting subprogram according to the long and short number of blade, stressed evenly for guaranteeing the workpiece cutting, adopting the symmetrical grooving mode, is 8 long 8 weak points as blade, behind 0 degree direction fluting, should open second groove in 180 degree directions, afterwards 45 degree, 225 degree, fluting successively.Machine the impeller material object that amplify for the 2.5%--3.5% ratio back, this compressor impeller custom is referred to as formpiston;

5. record resin former, fusing low melting point compressor impeller formpiston: with the compressor impeller formpiston after the milling, size according to profile puts it in the columned container made of iron, in vacuum drying oven, record the resin former, take out after 24 hours, put into basin, wash away with 100 ℃ boiling water, the low melting material impeller is melted, take off and make resin compressor impeller former, collect the low melting point molten material simultaneously, can reuse next time;

6. record the silicon rubber formpiston: after silicon rubber is stirred, turn over system silicon rubber formpiston, and repair processing in defective place;

7. turn over system gypsum former: turn over the silicon rubber formpiston of system more than inciting somebody to action, carry out the system of turning over of gypsum former;

8. use gypsum former cast aluminum impeller shaped article.
