Abstract

PURPOSE:To remove the burrs of a cast piece positively by disposing rotors alternately in such a way as to overlap the rotating loci of the respective sets of hammers of the adjacent rotors. CONSTITUTION:When a cast piece 8 is fed in the direction of an arrow mark 9, immediately before a burr 10 at the lower face of the cut face 8a of the cast piece 8 passes above a rotary shaft 1, the rotary shaft 1 is moved up and rotated as shown by an arrow mark 13, so that the head parts 6a of radially opened hammers 6 collide with the burr 10 by centrifugal force to remove the burr 10. In this case, the rotating loci of the adjacent hammers 6 are mutually overlapped, so that the head parts 6a of the respective hammers 6 come close to each other and collide with the burr 10 equally to enable the positive removal of the burr 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slab deburring device for removing the burr of a melted slab.

[0002]

2. Description of the Related Art Conventionally, a burr remover for loosely attaching a hammer base to the outer periphery of a rotor, rotating the rotor, and hitting the tip of the hammer to the slab of the slab by centrifugal force to remove the swell Known (JP-A-61-2364)
No. 12).

A study has also been reported in which the heads of adjacent hammers sandwiching the rotor are bulged to the rotor side to improve the problem caused by the gap between the hammer heads.

[0004]

In the disclosed invention, since there is no hammer in the portion corresponding to the thickness of the rotor, there is a problem that burrs remain depending on the material of the cast piece.

The improved hammer has been found to be effective in eliminating burrs remaining, but the improved hammer head is apt to be damaged, which causes a new problem in durability of the hammer.

[0006]

SUMMARY OF THE INVENTION However, the present invention solves the above-mentioned conventional problems by arranging adjacent hammers so that the loci of rotation of adjacent hammers overlap each other.

That is, according to the present invention, in order to remove the burrs of the slab that moves linearly, in a device that uses a hammer loosely attached to a roller, a set of two mounting protrusions provided on the rotary shaft at equal intervals is used. Multiple rotors are fixed, the pitches of the mounting protrusions of adjacent rotors are shifted so that the hammers do not contact each other, and a spindle is installed on the mounting protrusions for each rotor set, and the base of the hammer is attached to each spindle. The hammers of each set of rotors that are loosely attached and adjacent to each other are alternately arranged so that their rotation loci are overlapped with each other.
Further, the number of mounting protrusions is two to four, and the rotor is fixed to the rotating shaft at equal intervals.

In the above, the rotary shaft is installed at right angles to and parallel to the traveling direction of the slab, and as the slab moves, it rises to remove burrs and then descends.
No. 1-236412). Therefore, there is no possibility that the hammer hits the slab surface for the purpose other than deburring.

The number of the protrusions for mounting the rotor may be two to five. However, the two have a wide spacing and the five have a narrow spacing. 3 to 4 pieces are preferable.

As described above, in the present invention, since the loci of rotation of the hammer head are overlapped, it is possible to eliminate the deburring gap due to the existence of the rotor without changing the shape of the hammer head. Further, since the hammers can all have the same shape, they are compatible with each other, the number of parts is reduced, and it is not necessary to pay particular attention to them when assembling. Further, if the rotors are arranged at equal intervals, the balance will be improved.

[0011]

According to the present invention, since the loci of head rotations of the hammers in the adjacent sets of rotors are overlapped with each other, the deburring operation is performed uniformly and residual burr can be eliminated. Further, since all the hammers have the same shape, not only the rotation balance is good, but also the number of parts is reduced and the assembly is easy.

[0012]

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

To the rotary shaft 1 which is horizontally installed, the collar 2,
Through the rotor 3 (3a, 3b, 3c, 3d, 3
e, 3f, 3g, 3h, 3i) are fixed at equal intervals. At the periphery of the rotor 3, three mounting protrusions 4 (4
a, 4b, 4c) are provided, and the mounting protrusions 4 of the adjacent rotors 3 are fixed by being shifted by a half pitch. Therefore, the side view shows six mounting protrusions 4 as shown in FIG. In this way, since the mounting protrusions 4 overlap every other one, the common shafts 5 and 5 are inserted as a whole, and each shaft 5 is inserted.
And a set of rotors 3a and 3c, 3b and 3e, 3f
Between 5 and 3h, 3g and 3i, five hammers 6 and 6 are loosely attached. Shaft holes 7, 7 provided at the bases of the hammers 6, 6
Since the inner diameter of is larger than the outer diameter of the shafts 5 and 5, the hammers 6 and 6 can move not only in the rotation direction but also in the radial direction.

In the above embodiment, the slab 8 in FIG. 3 is fed from the direction of the arrow 9, and immediately before the burr 10 on the lower surface of the cutting surface 8a of the slab 8 passes above the rotary shaft 1, As the rotary shaft 1 rises as shown by arrow 11, the rotary shaft 1 rotates as shown by arrow 13, and the head 6a of the hammer 6 radially expanded by the centrifugal force collides with the burr 10, To remove. In this case, since the rotation loci of the adjacent hammers 6 overlap each other, the heads 6a of the hammers 6 are close to each other and evenly collide with the burr 10, so that the burr 10 can be reliably removed. it can. Thus, if the burr 10 is removed, the rotary shaft 1 descends as shown by the arrow 12, so that there is no risk of hitting the lower surface of the slab 8 unnecessarily.

[0015]

According to the present invention, since the rotation loci of the adjacent hammers overlap each other, the hammers uniformly collide with the burr regardless of the presence or absence of the rotor, and the burr can be reliably removed. However, since the hammers have the same shape, they are compatible with each other and are easy to assemble.
