Description of the Related Art A scroll type compressor used for a refrigerating compressor for refrigeration or air conditioning, an air compressor and the like employs an orbiting scroll in combination with a fixed scroll. That is, the orbiting scroll is set to face the fixed scroll fixed to the frame in the compression part formed in the closed container, and the orbiting scroll is orbitally operated by an electric motor via a crankshaft or the like. Is a spiral groove or wrap provided, and the operation of the orbiting scroll is obtained in a state where they are fitted to each other, so that the spiral closed space between both scrolls is moved to the central part and contracted. The refrigerant fluid that is confined in the space is compressed and led out.

That is, in Japanese Patent Application Laid-Open No. 54-159712, in order to avoid the difficulty of processing from a round bar material or the like before that, a preprocessed product having a scroll processing portion and a flange portion is formed as a first step. Then, it is proposed that a punch having a mold capable of forming a scroll shape is pushed in and the scroll portion is formed by backward extrusion forging.

Since the metal is destroyed when it is performed, it has been proposed to divide it into several stages and perform an intermediate annealing work to reduce strain hardening during that period.

It has been proposed to assemble and press-fit an upper punch having an engraving from the opening of the upper die to form the scroll portion and the flange portion at the same time.

しい製造条件の仔細は以下の如くである。The scroll of the present invention having the above component composition can be made into a product scroll by an appropriate method, but as a preferable production method, the ingot is subjected to homogenization treatment and then extrusion-molded, and this extrusion molding is carried out. The material is cut into a predetermined size, charged into a mold, and press-molded. The details of such preferable manufacturing conditions are as follows.

上限以内で処理することにより適切な素材が得られる。Preparation of ingot by homogenizing heat treatment and extrusion. A molten aluminum alloy having the above-described composition is obtained by a water-cooled semi-continuous casting method to obtain an ingot, and the ingot is homogenized at 480 ° C. for 2 hours or more to obtain a heat-treated structure in a uniform state. By extruding this at 350 ° C. or more at an extrusion ratio of 5 or more, eutectic silicon is finely and homogeneously dispersed to obtain a preferable material for press molding. Homogenization heating temperature is 55
If the temperature exceeds 0 ° C, the structure of the ingot changes, and it is industrially disadvantageous that the heating time exceeds 24 hours.
When the extrusion processing or the extrusion ratio is less than 5 as described above, it becomes difficult to obtain a press-molding material having an appropriate structure, and an appropriate material can be obtained by treating the material within the upper limit thereof.

By making the cross-section smaller by about 2 mm, it is possible to properly insert into the mold, to facilitate press molding, and to easily obtain a product having an accurate scroll diameter and structurally stable.

共に取扱いに難点を来す。Application of lubricant. By applying a lubricant of preferably 5 g / m 2 or more to the material prepared as described above, the subsequent press molding is facilitated. If the coating amount is 15 g / m 2 or more, the above effects are saturated, which is uneconomical and difficult to handle.

い。The material is heated to 430 to 480 ° C., and the press molding is performed at a pressing speed of 1 in a mold kept at 200 to 250 ° C.
By carrying out at 8 to 66 mm / min, the press molding process can be performed smoothly. When the material is pressed and formed, processing heat is generated, and the temperature of the material rises to facilitate the formation of the spiral scroll portion. That is, the material heated to 430 to 480 ° C generates heat during press molding and the temperature rises, while the heat of the material is absorbed by the mold heated to 200 to 250 ° C and the temperature at which the texture of the material does not deteriorate. The scroll is pressed from the disc-shaped material in a single step, and when the material is heated to 480 ° C or higher, the mold temperature is 250 ° C or higher, or the pressing speed is 66 mm / min or higher, This is not preferable because the temperature rises and partial dissolution occurs, which deteriorates the tissue. Also, if the heating temperature of the material, the temperature of the mold, the extrusion speed is below the lower limit, it is difficult to keep the temperature of the material sufficiently high,
In the pressure molding, the scroll cannot be molded in a single step.

This was sent to a tunnel type continuous heating furnace and made into a disc-shaped material that was heated to 450 ° C.
The disk-shaped raw material was loaded into a die having a scroll cavity of 90 mmφ which was heated and maintained at 90 ° C., and a graphite lubricant was diluted with mechanical oil into the cavity, and was press-molded.

The spiral scroll portion 2 having a thickness of 3 mm was formed in a triple state and the shaft portion 3 was provided on the other surface of the flange 1 in a protruding manner. Accurately shaped as height and thickness, its cross-section is shown separately in FIG.

た。On the other hand, the heating temperature of the material is 400 ° C., the heating temperature of the mold is 170 ° C., and the press molding speed is 50 mm / min.
In such a case, even if the other conditions are exactly the same as those in the above-described embodiment, the pressure molding in the spiral scroll portion formed on one surface of the flange 1, particularly in the central portion, cannot be properly obtained, and the partial molding is partially performed. The occurrence of defects was unavoidable.

Even if it is the same as the case of the example, the metal structure in the scroll portion 2 and the like obtained by press molding has a variation in the density and the density is insufficient, and stable product performance cannot be obtained.
