Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0028] Such as figure 1 and figure 2 As shown, the adjusting device for adjusting the angle of the rod loosening machine in the embodiment of the present invention includes:

[0029] platform 10, the platform 10 has, for example, a circular central hole for accommodating the turntable 1;

[0030] The turntable 1 arranged in the center hole of the platform 10 is covered or connected with a pressure plate 2. The turntable 1 is, for example, disc-shaped, and the outer wall of the turntable 1 is a cylindrical surface; Can turn in the hole formed in the backing plate of the bushing and wedge.

[0031] The locking groove (not labeled in the figure) for locking the turntable 1 is set on the edge of the central hole, the first end of the locking groove is an inner slope, ...

Abstract

The invention provides a rotating angle adjusting device for a mandrel bar loosening mill. The rotating angle adjusting device for the mandrel bar loosening mill comprises a platform (10), a rotary disk (1), tapered wedges (4), a locking hydraulic drive unit and a rotating angle oil cylinder (9). The platform (10) is provided with a center hole; the rotary disk (1) is arranged in the center hole of the platform (10), and a locking groove used for locking the rotary disk (1) is formed in the edge of the center hole; the first end of the locking groove is an inner side inclined plane, the second end of the locking groove is an opening, and the opening is connected to the outer wall of the rotary disk (1); the tapered wedges (4) are arranged in the locking groove; the locking hydraulic drive unit is connected with the tapered wedges (4); the rotating angle oil cylinder (9) is connected to a support (12) and is connected with the rotary disk (1). The rotating angle adjusting device is simple and compact in structure, the adjusting scope of an inclined angle of a mandrel bar loosening roller is large, detection accuracy is high, the inclined angle of the mandrel bar loosening roller is easy to detect, and the mandrel bar loosening roller can be locked rapidly and automatically.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a rotation angle adjustment device used in a skewed roll loosening machine in a seamless steel pipe production unit, that is, a rotation angle adjustment device for a loosening machine. Background technique [0002] The skewed roll loosening machine is mainly used in the seamless steel pipe jacking production line, and is widely used in the metallurgical industry. The steel pipe held tightly on the mandrel is rolled by the loosening machine to create a gap between the steel pipe and the mandrel. [0003] The loosening roll angle of the inclined roll loosening machine needs to be adjusted according to the diameter of the rolled pipe, and the adjustment accuracy is high. During the rolling process, the roll is subjected to a rotational force along the circumferential direction, and the lock can only work after the rotation angle is adjusted. [0004] At present, the common corner lockin...
