End face center, helicon tooth is distributed the surrounding for being arranged on spherical concave volume；Its manufacturing process comprises the following steps：1. blanking：Press
Product design figure requires the metal bar of selection respective diameters, length needed for interception；2. base：Peeling chamfering removes surface and lacked
Fall into；3. ball blast：Blank is put into blasting treatment in crawler type shot-blasting machine；4. coating：Blank surface coats graphite；5. warm forging is extruded
Shaping：By the good blank heating of coating to 860 ± 20 DEG C, mould is heated to 220 ± 20 DEG C, first jumping-up extruding, formed big end and
Bar portion；Preform is extruded again, forms spherical concave volume；Then forging is extruded into shape, forms helicon tooth；6. residual heat annealing：Warm forging is squeezed
Blank is immediately fed into annealing furnace and carries out residual heat annealing after pressing formation；7. sandblasting：Blank after annealing is put into drop hanger formula shot-blasting machine
Middle carry out blasting treatment；8. phospholeum：Blank surface after blasting treatment is subjected to phosphatization, saponification process；9. cold forging squeezes finishing：
By above-mentioned steps 8. in the big end of blank put upside down in cavity plate, by hydraulic press helicon tooth is carried out under normal temperature condition cold
The forging extruding finishing flank of tooth；10. it is heat-treated：Carburizing and quenching processing.
The bar portion of described automobile air conditioner compressor helicon gear is provided with centre bore, spherical concave volume bottom provided with recessed
Hole, centre bore is communicated with shrinkage pool and aperture is more than the aperture of shrinkage pool；Described bar portion outer wall is provided with straight trough, described center
Hole, shrinkage pool and straight trough are formed by machine tooling, and its machine tooling step is arranged on before heat treatment step.
The present invention has the advantages that compared with prior art：
The present invention can be retained forging and be squeezed using the automobile air conditioner compressor Luo rotation angular wheels of the cold compound forging extruding process manufacture of temperature
The complete metal streamline of shaping, this process synthesis applies the advantage of the cold compound forging extruding process of temperature, and formed tooth is squeezed in the cold compound forging of temperature
Face, is subsequently not required to carry out machining, product quality uniformity is good, and teeth portion forming accuracy is high, intensity is high, instead of direct bar
Or machining after hot forging, indices can meet the technical requirement on design of automobile air conditioner compressor screw conic tooth, save
Raw material, improve production effect, reduce production cost, shorten the production cycle.
