Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] Before describing the embodiments of the present invention, refer to Figure 1 ~ Figure 4 , a heat treatment apparatus for performing heat treatment suitable for the present invention will be described.

[0045] exist Figure 1 ~ Figure 4 The heat treatment carried out in (the heat treatment suitable for the present invention) is constituted by performing the quenching of the first step and the quenching of the second step.

[0046] In the quenching of the first step, in figure 1 In a region shown as "Q1" in , quenching is performed throughout the entire wall thickness of the hollow cylindrical shape workpiece 11 .

[0047] In the quenching in the above-mentioned first step, while rotating the hollow cylindrical workpiece (workpiece: for example, a bushing for a crawler belt) 11 around the axis of the workpiece, the workpieces 11 are continuously moved in the...

Abstract

It is an object of the present invention to provide a system that can cool the inner peripheral surface side of the workpiece in addition to heating and cooling the outer peripheral surface side of the workpiece, and can uniformly and continuously cool the inner peripheral surface side of the workpiece. The ground cooling heat treatment system and heat treatment method include: a conveying device for conveying a hollow cylindrical workpiece (11); an induction heating device (16) for heating the hollow cylindrical workpiece (11) from the outer peripheral surface; a cooling device (17 ), cooling the hollow cylindrical workpiece (11) from the outer peripheral surface side; the delivery side injection device (22N) and the delivery side injection device (21N), from the front end toward the inner circumference of the hollow cylindrical workpiece (11) The cooling range of the surface is sprayed with cooling medium; the moving device (22) of the spraying device on the delivery side moves the spraying device (22N) on the delivery side; the moving device (21) of the spraying device on the input side moves the spraying device ( 21N) Move.

Description

technical field [0001] The present invention relates to a technique of continuously cooling the inner peripheral surface side of a plurality of hollow cylindrical workpieces (for example, bushes of caterpillar tracks). More specifically, when heat-treating (quenching) a plurality of hollow cylindrical workpieces, it relates to a technique of continuously cooling the inner peripheral surface side of a plurality of heated workpieces. Background technique [0002] The hollow cylindrical workpiece includes, for example, a bush as one of parts for a track of a construction vehicle. However, it is not limited to the bush. [0003] In a hollow cylindrical workpiece such as a track bushing, the inner peripheral surface, the inner peripheral portion in the vicinity thereof, the outer peripheral surface, and the outer peripheral portion in the vicinity thereof are required to have hardness for ensuring wear resistance. At the same time, toughness for preventing cracking is required ...
