Abstract

The invention discloses a manufacturing method for aluminum alloy moving and fixed plates of a scroll compressor. According to the manufacturing method, an extrusion molding method is adopted for forming, and the aluminum alloy moving and fixed plates without casting defects of the scroll compressor are obtained; the defects that when molten metal is injected to enter a mold casting cavity, air is easily involved in and misrun of the molten metal is caused are overcome, aluminum alloy moving and fixed scroll plate products with no casting defects and high quality can be effectively manufactured, the material consumption is reduced, and the machining time is shortened.

Description

Screw compressor aluminium alloy moves, the manufacture method of price fixing
Technical field
The parts that the invention belongs to screw compressor manufacture field, are specifically related to that a kind of screw compressor aluminium alloy moves, the manufacture method of price fixing.
Background technology
Screw compressor belongs to the compressor of a kind of positive displacement compression, and compression member is by orbiter and determine scroll plate and form.Screw compressor mainly runs part whirlpool dish and only has dirty to close not wearing and tearing, and thus the life-span is longer, is described as freedom from repairs compressor; And novel structure, precision, have that volume is little, noise is low, lightweight, vibrate the advantages such as little, energy consumption is little, the life-span is long, gas transmission continuous and stable, reliable, source of the gas is clean, be described as " new revolution compressor " and " without the need to keeping in repair compressor ", be pneumatic machinery ideal power source, be widely used in industry, agricultural, communications and transportation, medicine equipment, food decoration and the industry such as weaving and other needs compressed-air actuated occasion.
But screw compressor has a lot of key technical problem to need to solve when producing in enormous quantities, the production in enormous quantities quality that guarantee is stable.Especially orbiter and the quality of determining scroll plate are directly connected to the reliability of compressor.In prior art, general employing pouring procedure or overall cutting process manufacture dynamic, price fixing, but air is easily involved in when its shortcoming is to enter die cavity with motlten metal injection, and motlten metal misrun, these defects easily cause screw compressor aluminium alloy dynamic, determine scroll plate and there is casting flaw, affect the quality of compressor.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide that a kind of screw compressor aluminium alloy moves, the manufacture method of price fixing.The method is shaping by extrusion process, and the obtained screw compressor aluminium alloy without casting flaw moves, price fixing, effectively reduces material consumption and machining man-hour.
For achieving the above object, the present invention adopts following technical scheme:
Screw compressor aluminium alloy moves, a manufacture method for price fixing, adopts extrusion process shaping, and the obtained screw compressor aluminium alloy without casting flaw is dynamic, price fixing.
Described screw compressor aluminium alloy moves, the manufacture method of price fixing, comprises the following steps:
1) pre-treatment of raw material: furnace chamber is warming up to 490 DEG C-530 DEG C in 15-20min, then the raw material shove charge will got ready in advance, during shove charge, temperature drops to 460-470 DEG C, continues to be warming up to 500-510 DEG C in 15min, be incubated 25min at this temperature, come out of the stove;
2) extruded: mold temperature is 430-470 DEG C, initial forging temperature is 480-510 DEG C, and squeeze pressure is 125KN/CM2, constant voltage time >=2s, and part mold clearing temperature is 480-525 DEG C;
3) shaping after-baking: hardening heat is 480-510 DEG C, part leaving water temperature < 150 DEG C.
The screw compressor aluminium alloy that a kind of manufacture method as above obtains is dynamic, price fixing.
beneficial effect of the present invention is:
(1) the present invention adopts specific heating temperature curve to heat raw material, adjustable aluminium alloy phase structure; (2) extruded on special mould, reduce material consumption and reduce following process man-hour, improve production efficiency;
(3) Technology for Heating Processing after extruded can make materials consumption rate decline 35%, and presentation quality and dimensional accuracy high; Without casting flaw.
Accompanying drawing explanation
The product photo that Fig. 1 embodiment 1 is obtained;
Fig. 2 is heating curves.
