するようにしたものが提案されている。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a scroll that is a component of a scroll compressor or the like. [Prior Art] As is well known, a scroll is composed of a spiral body 11, an end plate 12, and a mounting shaft 13, as shown in a perspective view of FIG. A method for manufacturing a scroll having such a configuration is, for example, as disclosed in Japanese Patent Application Laid-Open No. 61-99555, in which the scroll knob (volute body) is shaped in advance by a predetermined processing method. It has been proposed that the end plate is then molded by casting, and at the same time the end plate and the scroll lamp are fixed together to form a body.

しも十分とはいえなかった。That is, first, the scroll wrap member 51 is formed into a spiral band plate by plastic working or other forming methods.
As shown in FIG. 2, through the spiral groove 538 of the shell mold 53 loaded on the upper surface of the lower casting mold 52, the end plate is cast into the lower casting mold 52 on one side and the upper casting mold 54 on the other side. Move to position yourself in space. In addition, prior to this, the entire surface of the scroll lamp member 51 or only the portion that is to come into contact with the molten metal is coated with copper plating, tin plating, or copper or tin paste in order to strengthen the bonding force with the casting. It has been decorated. Then, the scroll wrap member 51 is inserted into the lower casting mold 52.
After finishing the centrifugation, as shown in the figure, the boss member core 55
, a casting upper mold 54 with a sprue 56 etc. provided at a predetermined location is placed over the casting lower mold 52, and a mold matching guide pin 57 is placed over the lower casting mold 52.
The lower mold frame 52a and the upper mold frame 54a are joined together, and molten casting metal is poured from the sprue 56. Thereafter, the lower casting mold 52 and the upper casting mold 54 are disassembled to take out the molded product. (Problems to be Solved by the Invention) However, although the above-mentioned conventional scroll manufacturing method is easy to process and has excellent mass productivity, it still has problems as explained below. This is a method in which a head plate having a (boss) is formed by gravity casting, and at the same time, this head plate and a scroll wrap formed in advance by a predetermined processing method are fixed, and these are integrally formed. Therefore, there is a problem in that internal defects such as shrinkage cavities are likely to occur in the head plate.Furthermore, since gravity casting is used, the reliability of the joint between the head plate and the spiral body is not necessarily sufficient.

製作方法の開発が望まれていた。By the way, as the performance of scroll-type compressors has recently improved, the spiral body of the scroll is required to have excellent wear resistance and fatigue strength. Therefore, in order to provide the spiral body with these properties and use an inexpensive material such as cast iron or cast steel, and to reduce the weight of the entire scroll, there is a scroll that uses an aluminum alloy for the head plate. When manufacturing scrolls made of different materials, methods such as mechanically fixing the spiral grooved end plate and the spiral body using screws, etc. are used, which is highly suitable for mass production. There was a desire to develop a manufacturing method.

た．This invention has been made in view of the above points, and involves shaping an mFL made of an aluminum alloy by molten metal forging, and at the same time fixing this end plate to a rolled body made of cast iron or cast steel. The purpose of this invention is to provide a scroll manufacturing method that can prevent the occurrence of internal defects in the end plate, more reliably and firmly fix the end plate and the spiral body, and is excellent in mass production. [Means for Solving the Problems] In order to achieve the above object, a method for manufacturing a scroll according to the present invention is such that a spiral body made of cast iron or cast steel is shaped in advance by a predetermined processing method, and then an aluminum alloy is formed. In a method for manufacturing a scroll that forms an end plate made of aluminum alloy and at the same time fixes this end plate and the spiral body to form them into one body, aluminum is applied to at least the portion of the spiral body that is to come into contact with the molten aluminum alloy. After spraying the aluminum alloy, the spiral body is placed in a mold for shaping the mirror plate, and the molten aluminum shell is poured into the mold.
The mirror plate and the spiral body are then integrally formed by pressurizing the molten aluminum alloy in the mold and forging the molten metal using a male punch having a spiral groove corresponding to the shape of the spiral body. There is. [Function] A spiral body having an aluminium alloy sprayed thereon is placed in a mold for shaping the mirror plate, and the molten aluminum alloy is poured into the mold at least on the part that should come into contact with the molten aluminium alloy. Then, the aluminum alloy i8 molten metal in the mold is pressurized using a male punch with a spiral groove to forge the molten metal.
As a result, the end plate made of aluminum alloy is formed while being pressurized and compressed, and at the same time, the spiral body made of cast iron or cast steel and the end plate are fixed. [Example] An example of the present invention will be described below with reference to the drawings. FIGS. 1(a) and 1(b) are explanatory diagrams of a scroll manufacturing method according to an embodiment of the present invention, and FIG. 1(a)

Materials such as JIS-I1-4032 materials are preferred. Then, as shown in FIG. 1(b), the male punch 5 is lowered to apply pressure to the surface of the molten aluminum alloy 7 in the mold 2.
This is molded and solidified while being pressurized and compressed. As a result, the end plate 9 made of aluminum alloy having the mounting shaft 8 can be formed by pressure compression without producing internal defects such as shrinkage cavities. Furthermore, in addition to the pressurized compression action, the adhesion is strengthened by applying the aluminum alloy thermal spray coating to the vortex body 6, so that the end plate 9 and the volute body 6 made of cast iron are firmly and securely bonded to each other. be able to. Next, the bottom plate 3 is pushed up into the mold 2 through the extrusion bottle 4 to release the large-sized product, and then machining is performed such as cutting the draft portion of the spiral body 6 to finish the scroll product. It will be done. In this embodiment, cast iron material was used for the spiral body, but cast steel may be used instead. (Effects of the Invention) As explained above, according to the method for manufacturing a scroll according to the present invention, an aluminum alloy is thermally sprayed in at least the portion that should come into contact with the molten aluminum alloy in the mold for forming the end plate. The molten aluminum alloy is poured into the molten aluminum alloy by positioning a spiral body, and the molten metal is pressurized by a male punch with a spiral groove for hot forging. The head plate made of aluminum alloy can be made to look impressive without causing any damage.In addition to the pressure compression action, the thermal spray coating on the spiral body strengthens the adhesion, so it is compatible with the spiral body made of cast iron or cast steel. It can be firmly and securely attached to the mirror plate. As a result, we were able to establish a manufacturing method with excellent quality and mass productivity for scrolls consisting of a spiral body made of cast iron or cast steel and a head plate made of aluminum alloy.
