Abstract
The utility model discloses a special tool for changing straightening rolls of straightening machines. The special tool is characterized by comprising an upper supporting plate and a lower supporting plate, and thrust bearings are arranged between the upper supporting plate and the lower supporting plate. The thrust bearings of the special tool are used as rotary devices, so that the upper supporting plate and the lower supporting plate can relatively and optionally rotate. When a pair of straightening rolls is changed, the lower supporting plate is fixed onto bearing blocks at two ends of the lower straightening roll, then the upper supporting plate rotates, the upper straightening roll is detached and drops on the upper supporting plate after the upper supporting plate is aligned with the upper straightening roll, the upper supporting plate rotates again, so that the upper supporting plate is aligned with the lower supporting plate, and finally the pair of straightening rolls is drawn out of a straightening machine by a traction apparatus; and a procedure is reversely carried out according to the steps when the straightening rolls are installed. The special tool is simple and reasonable in structural design and can be operated conveniently and quickly, changing time can be greatly shortened, and labor intensity can be greatly reduced.
Description
Technical field:
The utility model belongs to the auxiliary equipment of steel production and processing, is specifically related to a kind of straightener and changes the smoothing roll specific purpose tool.
Background technology:
Straightener is the crucial finishing equipment during seamless pipe is produced, smoothing roll in use for some time, because wearing and tearing or bearing locking must be changed.Smoothing roll is to use in pairs up and down, and a straightener has three pairs of smoothing rolls, every pair of horizontal cross arrangement of smoothing roll.When needing to change, by guiding mechanism, after aligning up and down, the every pair of smoothing roll that make the level intersection, is arranged above and below smoothing roll could be shifted out straightener in pairs.But because the guiding mechanism fault rate of smoothing roll is very high, the straightener inner space is narrow, for changing the smoothing roll cost plenty of time, has a strong impact on the production direct motion.
Summary of the invention:
The utility model is the deficiency that overcomes in the background technology, provides a kind of straightener to change the smoothing roll specific purpose tool, and its structural design advantages of simple, convenient to operation can shorten the replacing time greatly, and greatly reduces labour intensity.
The purpose of this utility model is achieved in the following ways: this straightener is changed the smoothing roll specific purpose tool, it is characterized in that: comprise mounting plate and bottom plate, be provided with thrust bearing between described mounting plate and the bottom plate.
Preferably, be equipped with block on the upper surface of described mounting plate, the lower surface of bottom plate, the both sides that block takes off plate near mounting plate, down arrange.
The beneficial effects of the utility model are: this straightener is changed the smoothing roll specific purpose tool,, makes between mounting plate and the bottom plate and can relatively and arbitrarily turn as whirligig with thrust bearing.When changing smoothing roll, bottom plate is fixed on the bearing block at lower smoothing roll two ends, then rotates mounting plate, align behind the upper straightening roll it is disassembled and drop on the mounting plate, rotate again mounting plate mounting plate and bottom plate are aligned, utilize at last draw-gear that a pair of smoothing roll is pulled out straightener; During installation, carry out according to reverse procedure.The utility model
Structural design advantages of simple, convenient to operation can shorten the replacing time greatly, and greatly reduces labour intensity.
Description of drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
The specific embodiment:
Miserable in Fig. 1 and Fig. 2, this straightener is changed the smoothing roll specific purpose tool, it is characterized in that: comprise mounting plate 2 and bottom plate 3, be provided with thrust bearing 1 between described mounting plate 2 and the bottom plate 3.Be equipped with block 4 on the lower surface of the upper surface of mounting plate 2, bottom plate 3, the both sides that block 4 takes off plate 3 near mounting plates 2, down arrange.This specific embodiment, makes between mounting plate 2 and the bottom plate 3 and can relatively and arbitrarily turn as whirligig with thrust bearing 1.When changing smoothing roll, bottom plate 3 is fixed on the bearing block at lower smoothing roll two ends, then rotate mounting plate 2, align behind the upper straightening roll it is disassembled and drop on the mounting plate 2, rotate again mounting plate 2 mounting plate 2 and bottom plate 3 are aligned, utilize at last draw-gear that a pair of smoothing roll is pulled out straightener; During installation, carry out according to reverse procedure.Adopt this device greatly to shorten the replacing time, and greatly reduce labour intensity.
