Description

[Detailed Description of the Invention] This invention relates to an inlet/outlet guide for rolled material in rolling without a gulliver, and particularly relates to an inlet/outlet guide for rolled material in rolling without a gulliver, in which the width can be freely adjusted while the guide is attached to a roll stand.

In rolling without a gulliver, it is possible to roll from large objects to thin objects by adjusting the gap between the upper and lower rolls.

At that time, the entry/exit log guide attached to the roll stand must also be replaced in accordance with the rolling dimensions, which has the disadvantage of requiring much time and effort.

Therefore, this invention was devised to solve the above-mentioned inconvenience, and its gist is that in the guide for the entry and exit of rolled material in rolling without a gulliver, the lower guide plate, the side guide plate, and the upper guide plate have a cross-sectional groove shape. A guide body is provided, and a movable guide plate is provided so as to face and be parallel to the side guide plates of this guide body. The movable threaded rod is connected to a movable threaded rod that is pivoted along the direction perpendicular to the flow direction, so that the movable guide plate can move toward and away from the side guide plate by rotation of this movable threaded rod. This consists in that the plate is provided with fixing screws for fixing it to the upper and lower guide plates.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a guide body, which is constructed by arranging a lower guide plate IA, a side guide plate IB, and an upper guide plate IC in a cross-sectional shape, that is, a U-shape.

Inside this guide body 1, there is a side guide plate IB.
The movable guide plate 2 is arranged by a movable screw rod 3 and a fixing screw 4 so as to be parallel to the movable screw rod 3 and the fixing screw 4.

The moving guide plate 2 has a substantially U-shaped cross section, and its upper mounting plate 2A1 and lower mounting plate 2B have fixing holes 5 through which fixing screws 4 are inserted to fix them to the upper guide plate IC and lower guide plate IA of the guide body 1. form.

Further, on the lower surface of the lower mounting plate 2B, a retaining piece 7 having a female screw 6 formed therein and screwed onto the movable threaded rod 3 pivotally supported on the lower guide plate IA of the guide body 1 is provided.

In the lower guide plate IA of the guide body 1, a moving groove 8 into which the engaging piece 7 is fitted is formed in a direction perpendicular to the moving direction of the rolled material.

A movable threaded rod 3 is disposed within the movable groove 8 so as to be rotatable along the length direction of the groove.

In addition, the lower guide plate IA and the side guide plate IB of the guide body 1 are provided at positions corresponding to the fixing holes 5 of the moving guide plate 2.
A long elongated hole is formed along the direction perpendicular to the flow direction of the rolled material to serve as the fixing screw insertion hole 9.

In addition, in the fixing screw insertion hole 9 formed in the lower guide plate IA, a head holding groove 10 for non-rotatably holding the polygonal head of the fixing screw 4 is formed to be wider than the opening of the fixing screw insertion hole 9 for fixation. It is continuous with the screw insertion hole 9.

The movable screw rod 3 has a collar 11 formed at the end of the shaft to prevent it from moving in the axial direction, and a movement restriction ring 1 at the center of the shaft.
The 2nd class is fixedly arranged.

In addition, numeral 13 in the figure is a support stand fixedly supported by a Muscovy duck or the like.

In use, rotate the movable threaded rod 3 with a spanner or handle, etc. to move the movable guide plate 2 to the side guide plate 1B.
Depending on the rotational direction of the movable threaded rod 3, the guide width is set to correspond to the gap between the columns (not shown).

Thereafter, by tightening the fixing screws 4, the movable guide plate 2 is fixed to the guide body 1 and used as an entry guide or an exit guide for rolled material.

This idea is constructed as shown above, and in the guide for the entry and exit of rolled material in rolling without a gulliver, the lower guide plate IA
A guide body 1 is provided by fixing a side guide plate IB and an upper guide plate IC so as to have a groove shape in cross section, and a movable guide plate 2 is disposed parallel to the side guide plate IB of the guide body. The moving guide plate 2 is provided as an upper guide plate IC.

The movable screw rod 3 is connected to one of the lower guide plates IA along a direction orthogonal to the flow direction of the rolled material, and the rotation of the movable screw rod 3 moves the movable guide plate 2 to the side guide plate. It should be possible to approach and leave the IB freely, and
The moving guide plate 2 includes an upper guide plate IC and a lower guide plate I.
Since the fixing screw 4 for fixing to A is provided, a width-adjustable loading/unloading guide for rolled material can be provided with a simple configuration.

Therefore, it is possible to eliminate the trouble of replacing the entry/exit log guide each time according to the rolling dimensions as in the conventional method, and enables efficient rolling operation.

Moreover, since movement of the moving guide plate 2 is performed by rotating the moving threaded rod 3, not only can the moving guide plate 2 be moved reliably, but also fine adjustments can be easily made to obtain accurate guide width dimensions. .

As explained above, according to this invention, it is possible to provide a guide for entering and exiting rolled material in rolling without a gulliver, which has a simple configuration and whose width can be freely adjusted.
This is an extremely useful device in practice, as it allows for fine adjustment, provides accurate guide width dimensions, and ensures reliable movement.
