ように思われる。As a method for manufacturing an aluminum deformed sleeve in which grooves are formed in the longitudinal direction of an aluminum slave during knurling, various methods have been used to date, but each method has its advantages and disadvantages, and there are still only a few that are worth considering. It seems to me.

という不具合があった。For example, in the method of hot extruding aluminum material by extruding it with a shaped die to make a shaped sleeve, the outer diameter tolerance is poor, so the yield rate is extremely low for products that require outer diameter tolerance. The drawback was that it got worse. Also, there is a known method of extruding aluminum material into a round tube using a round die through hot extrusion processing, and then forming it into a deformed sleeve using a deformed die through cold drawing. In order to obtain a deformed sleeve with the desired dimensions and shape in the next cold drawing process, the cold drawing process must be repeated two to three times, and during this process, the longitudinal direction of the drawn material is This has the drawback of increasing the number of scratches, dents, etc., resulting in poor yield. Furthermore, since the cold drawing process is not completed in one time, the overall cost tends to be high. Recently, a manufacturing method has been used in which a deformed tube is made into a deformed tube using a deformed die during hot extrusion, and then a deformed sleeve is made by cold drawing. In this case, the outer diameter tolerance is good and only one cold drawing process is required, but in this method, the profile groove pitch of the profile tube processed by hot extrusion and the profile groove pitch of the profile die in the cold drawing process are different. Even though it does not match perfectly, the drawing process is forcibly performed, and as a result, galling occurs at each location where the groove pitch between the drawn material and the irregular die does not match, and the drawn material and the irregular die There was a problem in that both the die and the die were easily scratched, and the life of the irregular die was extremely shortened.

要があった。Additionally, grooves are usually formed on aluminum sleeves by alumite treatment, painting, and etching (electrostatic powder coating).
X Some surface finishing treatment, cutting finishing processing, etc. were required, and it was necessary to include a considerable number of processing steps up to the processing of the layered final product.

d. An extrusion device as shown in FIG. 2 can be employed. For example, a billet 4 as an aluminum material A heated to about 500° C. is pressed and passed between a mandrel body 5 and a mandrel 6 provided thereon, to form a hole, and then integrated with the mandrel body 5. Grooves 1 of the same shape are formed in the longitudinal direction of the outer circumferential surface 2 using the irregularly shaped die 7, and a primary product 3a of a long (for example, 5 m) irregularly shaped tube 6 is obtained. In the example shown in Fig. 1, V-shaped parallel grooves 1 are formed, and the dimensions of the groove depth d and groove width l are determined by considering the cross-sectional reduction rate in the cold drawing process C as shown in Fig. i5. It is set as follows. Note that the shape of the groove 1 can be freely selected from U-shape, Cicada-shaped, V-shape, etc., and although not shown, these grooves 1 can also be formed on the inner peripheral surface.

T? It is something that is done. For example, a cold drawing process as shown in FIG. 4 can be adopted. First, it became thinner in the date process (not shown).
The tip of the sunken product 6a is pulled by the chuck 8, and the round die 9
By passing the primary product 3a between the plug 10 and the plug 10, the shear cut rrI) is reduced and the desired size is achieved. That is, primary product 6
The outer diameter of a, the groove depth d, and the groove width l are such that the respective dimensional changes are all absorbed by the difference in die diameter between the irregular die 7 and the round die 9, and the final dimensions are determined. Furthermore, a cutter (not shown) is used to cut the cutter for each predetermined dimension (e.g. 300 m
) is cut off.

Note that, hereinafter, parts similar to those in the first invention are indicated by the same reference numerals, and redundant explanation will be omitted. The primary product 3a that has passed through the hot extrusion process B is subjected to an IT treatment of the long irregularly shaped tube 6 in an alumite treatment process, so that an oxide film 11 is formed on the surface of the long irregularly shaped tube 6. Surface hardness is increased and corrosion resistance is provided. For example, in this alumite treatment process, hot extrusion process B involves degreasing to remove oil, etc. that has adhered to the primary product 3a, then rinsing with water, and further removing firmly adhered oil and finely processing the surface. In order to remove scratches, etc., the outer circumferential surface 2 of the primary product 3a is etched (C), for example, using about 5 ml of caustic soda at a temperature of 30 to 50 DEG C. for 2 to 7 minutes).

る。(→ As described in detail, according to the first invention, a long irregularly shaped tube with grooves is formed as a primary product, and the finishing process is performed as a primary product without using an irregularly shaped drawing die. The outer peripheral surface of the irregularly shaped pipe is drawn and finished using a finishing die whose finishing dimensions are the outside diameter, groove depth, and groove width of the irregularly shaped pipe. The problems that occurred when the irregular-shaped tube as a primary product and the groove pitch of the drawing die for secondary processing did not match have completely disappeared, and the irregular-shaped tube I?
'' does not cause scratches or dents in the direction for many years, and does not generate ripples on the drawing die. According to the second invention, in addition to the above-mentioned common effects, since the aluminum deformed sleeve is alumite treated before drawing, a hard acidic film is formed on the surface, which makes it difficult to use during drawing. , scratches, dents, etc. are eliminated, and the yield rate and + are greatly improved.Furthermore, as mentioned above, this alumite treatment increases the surface hardness of the p-type tube. Since corrosion resistance can be applied to the surface of the KIA type pipe at the same time as a normal surface finish, it is possible to omit the "alumite treatment" normally required as a surface finish treatment in the final process. Well, since alumite treatment can be carried out in the form of long irregularly shaped pipes, there is also the advantage that the process can be done at approximately half the cost of alumite treatment in the form of short tubes after drawing.
