Description

Guide Apron Roll Level Adjuster

The present invention relates to a guide apron roll level adjusting device. In particular, the level of the roll is automatically increased by rotating the adjusting bracket which is engaged to the upper portion of the support base by the amount of wear of the guide apron roll by contact with the billet. The guide apron roll level control device that can be adjusted.

In general, alignment of the guide apron roll has a great effect on the quality of the cast.

However, in the related art, since the bracket 20 for supporting the guide apron roll 11 is welded to the frame 21 as shown in FIG. 1, the height adjustment of the roll is almost impossible, thereby maintaining cast steel quality and equipment management. Provide problems.

In addition, there is a high risk of safety accidents due to the narrow space when repairing and adjusting the guide apron roll (11), the worker avoids work.

The present invention provides a guide apron roll level adjusting device capable of automatically adjusting the level of the roll by rotating the adjustment bracket which is engaged to the upper portion of the support base by the amount of wear of the guide apron roll by contact with the billet. Has its purpose.

In order to achieve the above object, the present invention includes a support base fixedly fixed to a lower portion of the frame; An adjustment bracket which is engaged with the upper portion of the support base and rotates in the circumferential direction along the guide hole; Both ends are rotatably supported by the upper limb adjustment bracket so as to be located at the upper portion of the frame, and provides a guide apron roll level adjusting device, characterized in that the shaft is configured to be externally rotated to guide the apron roll.

The configuration of the present invention will be described with reference to the drawings.

Figure 2 is a main perspective view showing a guide apron roll level adjusting apparatus according to the present invention, Figure 3 is an exploded perspective view showing a guide apron roll level adjusting apparatus according to the present invention, Figure 4 is a guide apron roll level adjustment according to the present invention Fig. 5 is a main part perspective view showing the level adjustment operation of the apparatus, and Fig. 5 is a main part perspective view showing the working status of the guide apron roll level adjusting apparatus according to the present invention.

First, a frame 21 spaced apart from each other by a predetermined interval is welded to the lower portion of the frame 21, and mounting grooves 17-1 in left and right axial directions are formed on the left and right upper surfaces of the frame 21, respectively.

At this time, the guide grooves 24 of the longitudinal direction are formed in the center, respectively, in the seating groove 17-1 into which the adjustment bracket 19 is inserted while the cross section is formed in a semi-circular shape, and the lower gear 26 is formed on the outside of the seating groove 17-1. Formed.

Here, the lower gear 26 formed in the circumferential direction along the seating groove 17-1 has a triangular cross section of teeth, and a height difference between neighboring teeth is 0.5 mm.

On the other hand, the adjustment bracket 19, which is installed so as to be seated in the seating groove 17-1, is positioned on the upper portion of the frame 21, the left and right lower surfaces form a semicircular curved surface, and upper gears 25 are formed on the lower surfaces, respectively. It is.

At this time, the upper gear 25 is engaged with the lower gear 26 to prevent the adjustment bracket 19 from rotating arbitrarily on the seating groove 17-1.

Here, the left and right side surfaces of the adjustment bracket 19 are marked with a roll level reference line 28 representing the center of the lower gear 26, and the roll level reference line 28 is displayed on the right side of the support base 17. Pointing at the center of the roll level scale 27, the adjustment bracket is located at the highest position.

In addition, fastening holes 23 are vertically formed at the centers of the upper and lower left and right surfaces of the adjustment bracket 19, and upper ends of the fastening bolts 18 penetrating the guide holes 24 in the fastening holes 23. Are combined.

In addition, support holes 19-1 are symmetrically formed on the left and right sides of the upper end of the adjustment bracket 19, and bushes 12 are inserted and fixed in the support holes 19-1, respectively, and the shafts 13 are fixed to the bushes. Both ends of the) are rotatably supported, and in particular, a fixing groove 13-1 is formed in the outer peripheral surface of the right end of the shaft 13.

Here, the guide apron roll 11 is externally mounted to the shaft 13 so as to be rotatable, and is attached to the upper end of the outer wall of the right adjustment bracket by a bolt so that the stopper 14 is inserted into the fixing groove 13-1.

Therefore, when the stopper 14 is inserted into the fixing groove 13-1, the shaft 14 stops rotating, and the apron roll 11 rotates around the shaft in a fixed state, and the apron roll due to wear It is possible to replace only the roll from the shaft when replacing.

Hereinafter will be described the operation of the present invention.

First, when the guide apron roll 11 is mounted on the frame 21, the level is adjusted by using the R-gauge 29. Then, when the outer peripheral surface of the guide apron roll 11 is worn by the cast steel, the diameter of the roll is used. Measure with a vernier caliper.

Then, in order to ascend by the amount of wear of the guide apron roll 11 measured by the vernier caliper, the fixing bolt 18 is first unscrewed and lowered, whereby a gap is generated between the adjusting bracket 19 and the support base 17. .

At this time, when the adjusting bracket 19 is lifted up, the upper gear 25 and the lower gear 26 are spaced apart to allow the rotation of the adjusting bracket, and when the roll level reference line 28 moves the roll level scales 27 one by one. Each time the upper gear is moved by one gear of the lower gear, one gear of the lower gear to move the height of the guide apron roll 11 by 0.5mm.

Here, as the roll level reference line 28 is moved toward the center of the roll level scale 27, the adjustment bracket is raised and the guide apron roll 11 is raised at the same time, so that the wear amount of the guide apron roll 11 measured by the vernier caliper is increased. By 0.5mm.

The present invention can precisely adjust the level of the roll, improve the quality of the cast, and repair the equipment by rotating the adjusting bracket which is engaged with the upper part of the support base by the amount of wear of the guide apron roll by contact with the billet. It provides the effect to prevent accidents that occur.
