Description
Technical field
The present invention relates to a kind of compressor of lamination impregnation screw rod, particularly relate to be formed by stacking after a kind of employing is inserted in axle by the toothed sheet parts of multi-disc and the compressor of screw axis of impregnation after quenching.
Background technique
Helical-lobe compressor, also screw compressor is claimed, comprise screw air compressor and screw rod technique compressor (vinyl chloride compressor etc.), helical-lobe compressor is divided into single screw compressor and double-screw compressor, and helical-lobe compressor utilizes screw axis shape rotor to compress and fed sheet of a media do rotation motion in cylinder body.
It is high that helical-lobe compressor has reliability, and component are few, do not have easily damaged parts, and thus its running is reliable, and the life-span is long, and general screw machine host header reaches 30 years projected life; Convenient operating maintenance, automaticity is high, and operator, without the need to through long-time professional training, realize unmanned running; Dynamical balancing is good, does not have unbalance inertia force, and machine can high speed operation reposefully, realizes foundation-free running; Strong adaptability, has the advantages that to force gas transmission, and volume flow is hardly by the impact of exhaust pressure, higher efficiency can be kept in the condition range of broadness, when compressor arrangement without any changes, be applicable to various working, thus be easy to sizing batch production; Multi-phase mixed delivering, in fact leaves gap between the rotor flank of tooth, thus ability hydraulic shock, can force feed containing the gas of liquid, containing dusty gas, easy polymerizable gas etc.; Guiding valve Flow-rate adjustment, do not need to return stream, can effectively reduce the advantages such as energy consumption, therefore, helical-lobe compressor is widely used.
The subject matter that current containment helical-lobe compressor develops is that the cost of helical-lobe compressor is high, the flank of tooth due to the screw axis rotor of screw machine is a space curved surface, the outer contour in its cross section is formed by connecting by the curve of multiple complexity, the curved surface of the flank of tooth of overall screw axis rotor is formed through spiral stretch by the external frame of above-mentioned complex curve, the flank of tooth of screw axis rotor is the curved surface of a complicated stereoscopic three-dimensional, therefore, turning common in machining and milling device not competent, numerical control turning general at present and milling device can not be processed, need to utilize special cutter to process on expensive special device in machining.
The processing of screw axis rotor, divides from product material, is generally divided into foundry goods cutting and forged steel pieces cutting.
The screw axis rotor that foundry goods cutting is shaped, necessary first cast form, then with machining center and dedicated tool cutting, the screw axis rotor that the quality such as rigid, wear resistance of product is cut relative to forged steel pieces is weaker.
During the screw axis rotor machining that forged steel pieces cuts, must first by steel formed by forging, then with machining center and dedicated tool repeatedly cutting, Quenching Treatment and surface finishing is carried out again after shaping, therefore, technological requirement is high, technological process is complicated, processing speed is slow, cost of production is high.
In actual production, production enterprise often adopts import machining center and import cutter to complete processing, and enterprise is when purchasing high-end import machining center, and be subject to the technology restriction of developed country, meanwhile, import equipment and import cutter substantially increase cost of production.
