Abstract
The utility model discloses a kind of automobile air conditioner compressor helicon gear of forging and molding, bar portion including big end and lower end whole installation, the end face held greatly is provided with spherical concave volume and helicon tooth, spherical concave volume is arranged on the end face center held greatly, and helicon tooth is distributed the surrounding for being arranged on spherical concave volume.It is overall structure, forging can be retained using the cold compound forging extruding process manufacture of temperature and be extruded into the complete metal streamline of shape, forging is extruded into the shape flank of tooth and is subsequently not required to carry out machining, and product quality uniformity is good, and teeth portion forming accuracy is high, intensity is high, it instead of machining after direct bar or hot forging, indices can meet the technical requirement on design of automobile air conditioner compressor screw conic tooth, save raw material, improve production efficiency, production cost is reduced, shortens the production cycle.
Description
Technical field
The utility model belongs to forging and molding technical field, and in particular to a kind of air conditioning for automobiles produced using finish forge technology
Compressor helicon gear.
Background technology
Automobile air conditioner compressor helicon gear is for passing power, while carries the moving parts of high pulling torque, right
Its accuracy of manufacture and Gear Surface Strength require very high, and prior art has two class production technologies：As soon as it is traditional cutting technology,
It is directly to use bar machining, this technique is simple, easily realizes and produces, but the automobile air conditioner compressor of this technique manufacture
The helicon strength of gear teeth is low, also a kind of production technology, is exactly blank heating forging using easily occurring tooth damage phenomenon after stress
Into gear blank, the then machining shaping flank of tooth.Both the above production technology is all using the machining shaping flank of tooth, metal
Streamline is cut off, and Gear Surface Strength is low, wastes raw material, and cutter consumption is big, and production effect is low, cost is high, production cycle length.
The content of the invention
A kind of accuracy of manufacture of the utility model offer is good, and intensity is high, and interior tissue density high metal line is smooth, and saves former
Material, production efficiency is high, and cost is low, the automobile air conditioner compressor helicon gear of cycle short forging and molding.
The utility model is realized by following technical solution：
The automobile air conditioner compressor helicon gear of forging and molding, including the bar portion of big end and lower end whole installation, greatly
The end face at end is provided with spherical concave volume and helicon tooth, and spherical concave volume is arranged on the end face center held greatly, the distribution of helicon tooth
It is arranged on the surrounding of spherical concave volume.
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 communicates 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.
The utility model has the advantages that compared with prior art：
The utility model beneficial effect is that described helicon gear is overall structure, and work is squeezed using the cold compound forging of temperature
The automobile air conditioner compressor Luo rotation angular wheels of skill manufacture, can retain forging and be extruded into the complete metal streamline of shape, forging is extruded into the shape flank of tooth
Follow-up to be 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 original
Material, production efficiency is improved, reduce production cost, shorten the production cycle.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment：Referring to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of automobile air conditioner compressor helicon gear of forging and molding,
Bar portion 2 including big end 1 and lower end whole installation, the end face at big end 1 are provided with spherical concave volume 3 and helicon tooth 4, spherical concave volume
3 are arranged on the end face center at big end 1, and helicon tooth 4 is distributed the surrounding for being arranged on spherical concave volume 3；During described bar portion 2 is provided with
Heart hole 5, the bottom of spherical concave volume 3 are provided with shrinkage pool 6, and centre bore 5 communicates with shrinkage pool 6 and aperture is more than the aperture of shrinkage pool 6；Described
The outer wall of bar portion 2 is provided with straight trough 7；Described centre bore 5, shrinkage pool 6 and straight trough 7 is formed by machine tooling.
Embodiment is not formed and protects model to the utility model only to facilitate understand the technical solution of the utility model
The limitation enclosed, it is every without departing from technical solutions of the utility model perhaps according to the technical essence of the utility model to top
Any simple modification, equivalent change and modification that case is made, still falls within scope of protection of the utility model.
