ランプして冷却を行なうものである。That is, the present invention provides a clamping device for a material, such as an upsetter pipe, in which the main pipe portion and the upsetter portions at both ends have different diameters, and such a clamping device has not been available in the past. With conventional tabs, pipes with the same diameter in the longitudinal direction are lowered from top to bottom in synchronized operation using multiple inverted V-shaped clamp metal fittings, and soft clamps (clamp contact surface and pipe (1 to 2 gaps are left between the pipe and the outer periphery) to restrain the pipe bending during cooling. Since there are various types of upsetters, the position of a part of the upsetter changes, making it difficult to develop a device that can respond to changes in clamping conditions. The present invention cools the steel pipe by clamping it regardless of whether the steel pipe is mounted on a saddle for cooling, regardless of whether it is in the mother pipe or in the upset part.

is arranged rotatably, and a saddle 11 is mounted on the eccentric cam 2o.
The height of the saddle 11 can be adjusted by rotating the eccentric cam 20. Furthermore, in the present invention, in order to keep the stroke amount of the lifting device 9 constant and restricting the rotation of the pawl 1, it is also possible to connect the lifting device 9 to the worm jack 15 and control the height of the foot of the lifting device 9. It is said that

両サイドからクランプする様になっている。After the steel pipes 13 are carried in and loaded onto the saddle 11 with the upper space open, the cylinders 9 connected one each to both ends of the rotation shaft 5 via the lever 7 and the bottle 8 are activated to rotate. The steel pipe 13 is clamped by rotating the shaft 5. Rotation axis 5
, the claws 1 are arranged on both sides of the steel pipe 13, and the claws 1 are arranged on both sides of the steel pipe 13' and
It is designed to be clamped from both sides.

上下方向の高さ微調整が可能な構造となっている。Since the saddle 11 supports the main pipe part 17 and the upset part 18i of the steel pipe 13, the slight rotation of the eccentric cam 20 provided at the bottom of the saddle 11 against the step δ causes
The structure allows fine adjustment of the height in the vertical direction.

爪１の製作、据付が容易となる。In addition, the height of the cylinder 9 can be adjusted using a worm jack 15 according to the outer diameter of the steel pipe 13, and it is always used at the stroke end, so that the claw 1 touches the steel pipe 13 just before the stroke end. After contacting the outer surface, the claw 1 retreats relative to the rotating shaft 5 within a gap Δ and clamps the steel pipe 13. At this time, the clamping force is
The value corresponds to the spring reaction force of the spring 14, and since the spring constant is small, a nearly constant clamping force is ensured. In response to deformation of the steel pipe 13 during quenching, the spring 14 cannot be displaced by more than the gap 2, so the cylinder 9 restrains deformation resistance greater than the spring reaction force. In addition, by retracting the claws 1 in accordance with the gap Δ, even if there is slight unevenness in the level of each claw surface 11, it can be reliably clamped.
Manufacture and installation of the claw 1 are facilitated.
