点を有している。Traditionally, when manufacturing a hydraulic brake hose fitting a as shown in Fig. 9, drawn material was used to cut it to a predetermined length, and the subsequent hand part was used as a cutting tool such as a cutting tool. However, in this manufacturing method, the joint part is cut into a cylindrical shape from a material with corners, so the blade of a cutting tool etc. is easily chipped at the corners, and the life of the cutting tool is shortened. Because it is short and chucks material with low dimensional accuracy, processing accuracy is poor, and the base C of the joint part
In this method, the strength of the joint part is reduced by cutting the flow line of the material, resulting in a low yield.

んとするものである。In addition, when manufacturing from a rod-shaped material, use one with a smaller diameter than the base d of the hydraulic brake hose fitting a, first inflate it to the same shape as the base d, and then extrude the joint part. However, this method had the disadvantage that it was not possible to carry out continuous processing due to lack of timing when transferring to the next process.
The present invention provides a hydraulic brake hose port that facilitates the transfer of the molding process to improve mass productivity, extends the life of cutting tools, and improves strength by eliminating the need to cut the flow line at the joint. The present invention aims to provide a method for manufacturing metal fittings.

欠点を解消せんとしたものである。In view of these points, the present invention for solving the problem involves upsetting a flat material cut to a predetermined length and forming it into a bulge shape, and forming a protrusion portion of a predetermined diameter forward from the bulge portion. Provided is a method for manufacturing a hydraulic brake hose fitting, which comprises a first step in which extrusion is carried out substantially simultaneously, and a second step in which the bulged portion of the formed material is formed into a bulged shape to a product shape. This is an attempt to eliminate the above drawbacks.

大なるものである。[Effects of the Invention] In short, the present invention provides upsetting to form a flat material W cut to a predetermined length G into a bulging shape, and a bulging portion 25.
A first step in which extrusion is performed to form a protruding portion 32 of a predetermined diameter further forward at the same time; and a second step in which the bulged portion 25 of the formed material-a is formed into a bulged shape to a product S shape. Since the process consists of two steps, the material W is formed into a bulging shape to form the bulging part 25, and at the same time, the protruding part 32 is extruded to a predetermined diameter from the bulging part 25 forward through the constriction part 10. This allows upsetting and extrusion, which were previously done in separate processes, to be done in one process.
By simplifying the process and facilitating the timing of transfer to the next process, continuous processing is possible and mass production is improved, and since the protrusion 32 is formed into a cylindrical shape, , reduces the burden on cutting tools such as bits, extends the life of the cutting tool, and since the cutting allowance during cutting of the protrusion 32 is small, even when the outer diameter of the protrusion 32 is cut. , there is no cut point at the flow line at the base 33 of the protrusion 32, and the strength is significantly improved compared to cutting the protrusion 32 directly from the conventional drawn material, so the yield of the product S is improved. The practical effects of this, such as being able to improve the situation, are enormous.
