ボルトにおいても製造されている。2. Description of the Related Art A washer-incorporated bolt incorporates a washer fitted and inserted in the bolt so as not to come off between the bolt head by forming a screw portion. The workability of the assembly process by a robot or the like is improved. This washer-incorporated bolt is standardized as a washer-incorporated hexagonal bolt (JISB1187) and a cross-recessed head screw (JISB1188). Nine high-strength hexagon bolts and hexagon socket head bolts are also manufactured.

に規定される硬さが付与されたものがある。[0003] In such a high-strength bolt, by performing a heat treatment at a predetermined temperature by quenching and tempering,
Strength and hardness specified in JIS are given. The spring washers used for the bolts are given the strength and hardness already specified in JIS during the production process. On the other hand, flat washers are provided with the hardness specified in JIS by rolls at the time of sheet rolling, or JIS by heat treatment.
Stiffness specified in Table 1.
【０００４】ところが、座金組込ボルトにおいては、ボ
ルトに座金を組み込んだ状態で、ボルトに熱処理を施し
た場合には、ボルトと座金では焼き戻し温度の適正値が
異なることから、座金の硬度が低下し、その硬さやばね
性（ばね座金の場合）が規格値を満足できないという問
題が生じる。However, in the case of a bolt with a washer built-in, if the bolt is subjected to a heat treatment in a state where the washer is incorporated in the bolt, the hardness of the washer is reduced because the appropriate value of the tempering temperature differs between the bolt and the washer. This causes a problem that the hardness and spring property (in the case of a spring washer) cannot satisfy the standard values.

程でねじ部を成形して製品としている。[0005] Therefore, conventionally, after forming the head and body of the bolt by the header, in order to obtain the strength and hardness specified in JIS, heat treatment is first performed only on the bolt blank, and then, A washer whose hardness and spring property (in the case of a spring washer) are already at a standard value is incorporated, and then a thread portion is formed in a rolling process to form a product.

いう問題があった。However, in the conventional method for manufacturing a washer-incorporated bolt, the bolt blank after heat treatment has a higher tensile strength and hardness than before heat treatment. When rolling,
There has been a problem that the life of a rolling tool such as a die is remarkably reduced to 1/4 to 1/5, and the manufacturing cost of a bolt with a washer is significantly increased.

じている。Further, in the method of manufacturing a single bolt, a screw blank is formed in a rolling process on a bolt blank having a head formed by a header, and then a heat treatment is performed to obtain a product. In the bolt manufacturing method, the order of the rolling process and the heat treatment process is reversed, so that the consistency of the manufacturing line is lost, and there is a problem that production management is confused.

An object of the present invention is to provide a washer assembling bolt capable of incorporating a washer into a bolt before a heat treatment step by selecting a material having a hardness of a standard value by quenching and tempering, and a method of manufacturing the same.

貫性を保って生産管理を容易にすることができる。According to the washer-incorporated bolts of the first to third aspects of the present invention, by specifying the materials of the bolt and the spring washer, the tempering softening resistance of the washer can be increased. Even when the same heat treatment as that of the bolt is performed on the spring washer in a state where the spring washer is incorporated in the bolt, required characteristics of the spring washer can be obtained. And since the spring washer can be incorporated into the bolt before the heat treatment process,
The rolling process can be performed before the heat treatment process, which makes it possible to manufacture washer-integrated bolts at low cost without shortening the life of the rolling tool, and in the same manufacturing process as a single bolt. Therefore, the production control can be facilitated while maintaining the consistency of the production line.

産管理を容易にすることができる。Further, according to the washer-incorporated bolts of the fourth and fifth aspects of the present invention, by specifying the materials of the bolt and the flat washer, the flat washer is assembled into the bolt in the same state as the bolt. Even if the heat treatment is performed, required characteristics of the flat washer can be obtained. And, since the flat washer can be incorporated into the bolt before the heat treatment process, the rolling process can be performed before the heat treatment process. Since it can be manufactured at low cost and can be manufactured in the same manufacturing process as a single bolt, it is possible to maintain production line consistency and facilitate production management.

Since the rolling process can be performed before the heat treatment process, the service life of the rolling tool is not shortened. Production management can be facilitated while maintaining the performance.
