この発明は、鋼管等の所謂長尺材の焼入れを行なう装置
に関し、特に被焼入材をその軸°心を中心に回転させつ
つ冷却する回転焼入装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a device for hardening so-called long materials such as steel pipes, and in particular to a rotary hardening device that cools a material to be hardened while rotating it around its axis. This is related to the input device.

して冷却水を噴射する冷却方法でも同様な不都合が生じ
る。Conventional technology For example, when quenching a steel pipe, if a red-hot steel pipe is simply placed in cooling water and immersed, the steam generated by the boiling of the cooling water may irregularly cover the surface of the steel pipe or cause damage to the outer circumferential surface of the steel pipe. A situation may arise in which the portion of the material that is in contact with the pedestal is not cooled, resulting in the inconvenience that uniform hardening cannot be achieved. Further, a similar problem occurs in a cooling method in which cooling water is injected onto red-hot steel pipes.

却する構成であり、被焼入材を静置して冷却する場合に
比べれば、より均一な焼入れを行なうことができる。Conventionally, a rotary hardening apparatus has been known as an apparatus that can eliminate the above-mentioned disadvantages. This is a configuration in which a turning roller that is rotationally driven and a pinch roller that approaches and moves away from the turning roller pinch the material to be hardened, such as a steel pipe, and cool it while rotating around its axis. Compared to the case where the material to be quenched is allowed to stand still and cooled, more uniform quenching can be achieved.

This method uses a clamp mechanism to grip the end of a steel pipe that is rotatably supported by a clamp row, and these clamp rows and clamp mechanism rotate the steel pipe and reciprocate in the axial direction. The structure is such that cooling water is injected onto both the inner and outer circumferential surfaces of the steel pipe to perform quenching.

グローラ１ａ。Problems to be Solved by the Invention However, the conventional rotary hardening apparatus described above has a lower pair of turning rollers ia, 1b and an upper pair of pinch rollers 2a, 2b as shown in FIGS. 4 and 5. As shown, these turning rollers 1a are arranged on the same plane along the radial direction of the steel pipe 3, so these turning rollers 1a are located on the outer peripheral surface of the steel pipe 3.

、２ｂのセット時に、ピンチローラ２ａ。1b and pinch rollers 2a', 2b, even if the steel pipe 3 is rotated, the degree of contact with the cooling water is lower than other parts, and as a result, cooling of the steel pipe 3 as a whole is insufficient. There were many cases where there was a uniform thud, and in extreme cases, the steel pipe 3 was bent significantly. Furthermore, conventional rotary hardening equipment generally has a configuration in which the turning rollers la and lb are fixed, and the pinch rollers 2a and 2b are moved up and down to pinch the steel pipe 3 and release the pinching. However, the pinch roller 2a when starting hardening
, 2b, the pinch roller 2a.

れなくなり、鋼管３の曲がりが発生する問題があった。If the axis of the steel pipe 2b is not parallel to the axis of the steel pipe 3 as shown in FIG. As a result, the steel pipe 3 moves in the axial direction, causing a change in the relative position between its end and the inner nozzle 4, and as a result, it becomes impossible to obtain the required amount of cooling water on the inner surface. There was a problem that the steel pipe 3 was bent.

として大規模かつ高価になる問題があった。On the other hand, in the quenching apparatus according to JP-A No. 57-185924 J- mentioned above, the target steel pipe is simultaneously rotated and at the same time actively reciprocated in its axial direction. It can be cooled and uniform hardening is possible. However, in the apparatus according to the above proposal, since the end portion of the steel pipe is continuously held by the clamp mechanism, there is a problem in that the end portion of the steel pipe is insufficiently quenched. In addition to the mechanism for reciprocating the steel pipe in the axial direction, it is also necessary to have a mechanism to stably supply cooling water to the inner surface of the steel pipe even when it moves in the axial direction, so the equipment as a whole is large-scale. There was also the problem that it was expensive.

In the rotary hardening device, the two lower rollers are arranged offset in the axial direction of the material to be hardened. Further, each of the two upper rollers is disposed offset from each other in the axial direction of the material to be quenched so as to substantially oppose each of the lower rollers on the diameter of the material to be quenched. Another feature of the present invention is that a holder to which the upper roller is rotatably attached,
It is attached to a movable seat that approaches and separates from the lower roller so that it can rotate freely about the axis along the radial direction of the upper roller.

い。Function: Therefore, in the rotary hardening apparatus of the present invention, rollers having only one hook each on the upper and lower sides contact specific points on the outer circumferential surface of the material to be hardened to support and rotate the material to be hardened. The area covered by the roller at a specific location on the outer circumferential surface is reduced. In addition, by making the holder with the upper roller attached freely rotatable around the axis along the radial direction of the upper roller,
The external force accompanying the rotation of the material to be quenched is automatically set so that the upper roller is parallel to the material to be quenched, so that no thrust is generated in the axial direction of the material to be quenched.

Among these rollers, the lower rollers 12a and 12b are arranged slightly offset from each other in the axial direction of the steel pipe 10, and are attached to mutually parallel rotating shafts 15a and 15b that are rotated in the same direction by a motor 14. Therefore, the lower rollers 12a and 12b serve as turning rollers on which the steel pipe 10 is placed and rotated. On the other hand, upper O-

a, 12b are rotated by the motor 14 (thus, the steel pipe 10 is rotated. In this state, the steel pipe 10 is immersed in cooling water, or cooling water is injected from the outer surface side, and a cooling water flow is applied to the inner surface side. Perform hardening.

一に冷却することができる。During such a cooling process, a specific location on the outer circumferential surface of the steel pipe 10 repeatedly comes into contact with the rollers.
In the above-mentioned device, since the lower rollers 12a, 12b and the upper rollers 13a, 13b are positioned offset from each other in the axial direction, one lower roller 12a ( or 12b) and one upper roller 13a (or 13b), for a total of 42 pieces, so even if a specific part of the outer circumferential surface repeatedly contacts the roller, the degree to which it is hidden from the cooling water by that roller is small. , as well as other parts, are cooled as necessary and sufficient. That is, the entire outer peripheral surface of the steel pipe 10 can be uniformly cooled.

合でも、両者の相対位置が変化しない。Furthermore, in the device described in -F, the upper rollers 13a and 13ti are configured to be able to freely rotate around the rotating shafts 18a and 18b, so the upper rollers 13a and 13ti contact the 13-bit steel pipe 10 and rotate together with the steel pipe 10. As a result, the steel pipe 10 becomes parallel to the steel pipe 10 due to an external force such as frictional force, and misalignment of the cellar 1 or misalignment caused by uneven wear can be automatically corrected. Therefore, in the above device, even if a thick-walled pipe is cooled for a long time, the steel pipe 10 will not move in the axial direction due to thrust during cooling, and even if the inner nozzle is disposed at the end of the steel pipe 10, Even if there is, their relative positions do not change.

を簡単なものとすることができる。Effects of the Invention As is clear from the above explanation, according to the rotary hardening apparatus of the present invention, the upper and lower rollers are arranged so that one roller is located at the same cross-sectional position along the radial direction of the person to be burned. Therefore, the degree to which specific parts of the outer circumferential surface of the burnt person are hidden from the cooling water by the rows used to hold and rotate the burnt person is extremely small, and therefore uniform quenching is achieved without uneven heating or hardness. By doing this, you can obtain a product without bending. Moreover, since the device of the present invention does not require reciprocating the burnt person in the axial direction, the structure can be simplified.

品を得ることが可能となる。In addition, by configuring the upper roller, which is a pinch roller, to rotate around its axis along the radial direction, the misalignment of the upper roller with respect to the person to be burned is automatically corrected, and therefore the component of rotational force is reduced. Since no thrust is generated along the axial direction of the burnt person, there is no movement in the axial direction even when the burnt person is targeted for thick-walled items that require long rotation and cooling. Therefore, the relative position with respect to the nozzle that supplies cooling water to the inner surface does not change, and as a result, uniform cooling can be achieved from both the inner and outer surfaces, and in this respect, it is also possible to obtain a product without bending.
