た部材の焼入装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quenching device for a member having a curvature, which quenches a shaft-shaped member curved to one side with a predetermined curvature.

There is a technique disclosed in Japanese Utility Model Publication No. 52-34331.

と、内側面側が伸び、外側面側が縮むなどの変形を生じ
てしまい、上述の従来技術では、このような変形を防止
しながら焼入れを施すことは困難であった。A shaft-shaped member curved to one side with a predetermined curvature has a compressive force on the inner side surface and a tensile force on the opposite side due to the processing into the predetermined shape. Therefore, when such a shaft-shaped member is subjected to quenching treatment at a high temperature, deformation occurs such that the inner side surface side expands and the outer side surface side shrinks. In the above-described conventional technology, quenching is performed while preventing such deformation. Was difficult to apply.
【0004】そこで、このような変形を防止しながら焼

れていた。Therefore, as a technique for quenching while preventing such deformation, the following means have been conventionally used.

エーションに対応して、送り用治具への軸状部材のボル
ト留め位置が変更できるようになっている。The first means is to manually bolt a curved shaft-shaped member to a feeding jig, which is a trolley-like member for moving the shaft-shaped member to be hardened, and then use the bolt to clamp the shaft-shaped member. While preventing the members from being deformed, the shaft-shaped member is moved by the feeding jig and the induction heating coil is used for quenching. Further, in such a technique, the bolting position of the shaft-shaped member to the feeding jig can be changed according to the variation in the curvature of the shaft-shaped member.

The shaft-shaped member is moved and quenched by an induction heating coil while being prevented from being deformed by being supported by two facing free rollers.

るものである。As a technique for quenching a straight shaft member having no curvature while preventing it from being deformed, Japanese Patent Publication No. 56-80
There is a technique disclosed in Japanese Patent Publication No. 89. This technique uses a straight shaft-shaped member with no curvature as its axial direction is horizontal, and the center portions of both axial end faces are supported by two centering pins, and two axially-arranged members are arranged at a predetermined interval. A roller supports the peripheral surface of the shaft-shaped member from below, and the induction heating coil is moved along the axial direction of the shaft-shaped member for quenching. Further, an upper pressing roller that is a single roller that moves in conjunction with the induction heating coil and presses the peripheral surface of the shaft-shaped member from above is also formed, and two rollers that support the shaft-shaped member from below and one roller. In cooperation with the upper presser roller, quenching is attempted while suppressing deformation.

ばならず、焼入れ作業がきわめて煩雑である。However, the above-mentioned first means for quenching the shaft-shaped member curved to one side is such that the shaft-shaped members to be quenched are manually worked one by one in order to prevent deformation due to quenching. Therefore, it is necessary to fasten the bolts at a plurality of points and remove the bolts after the quenching is completed, which makes the quenching work extremely complicated.

面側へ湾曲するような変形が生じやすい。Further, according to this means, since the curved shaft-shaped member is fixed and moved to the feeding jig which is a dolly-like member, the fixed side of the shaft-shaped member to the feeding jig is fixed. The surface (lower surface) and the lower portions of the inner and outer surfaces (both side surfaces) due to the curvature following this surface cannot be hardened, and are likely to be deformed to curve to the upper surface side.

を十分に防止することが出来ない。On the other hand, in the above-mentioned second means, the shaft-shaped member is only supported by the two rollers at two curved positions in the axial direction so as to sandwich the shaft-shaped member from both sides. The member cannot be reliably restrained, and the deformation due to quenching cannot be sufficiently prevented.
