Description

Wire Rod Polishing Machine {A POLISHING MACHINE FOR WIRE ROD}

The present invention relates to a wire rod polishing apparatus, and more particularly, to a wire rod polishing apparatus capable of continuously grinding and polishing thin and long wire rods and preventing environmental pollution.

Wire rods are generally referred to as long and thin of round steel, and are manufactured through a series of processes such as drawing, extrusion, hot or cold rolling. Hot rolling is to change the length and cross-sectional area of the wire rod after applying constant heat to the processed wire rod, cold rolling is to change the cross-sectional area of the wire rod at room temperature. At this time, in the process of processing the wire rod through hot or cold rolling, a lot of scale and scratches are generated on the surface of the wire rod, a polishing process for polishing the wire rod surface is required to remove them.

Therefore, conventionally, the surface of the wire rod was polished by an electropolishing method in which the wire rod was immersed in a polishing liquid made of acetic acid-perchloric acid or the like. In other words, electropolishing is performed by electrolyzing the wire as an anode, as opposed to electroplating, so that a polished polished surface can be obtained.

However, in the conventional wire polishing method, the surface gloss of the wire rod is insufficient after polishing, and there is a problem of environmental pollution caused by the polishing liquid made of chemicals, and the waste water treatment cost is increased.

The present invention is to solve this problem; SUMMARY OF THE INVENTION An object of the present invention is to provide a wire polishing apparatus which can grind and polish the surface of a wire to significantly improve surface gloss and at the same time prevent environmental pollution.

In addition, the rotation shaft 51 of the polishing motor 50 is made of a different length, so that the rotation position of the polishing wheels 60 are shifted from each other.

Such polishing motors 50 are preferably mounted to be slidably moved by a predetermined distance in the radial direction from the side wall 31 of the rotary drum 30 through the sliding fixing means 80, which is the diameter and polishing of the wire (A) This is to adjust the interval with the wire rod (A) according to the wear of the wheels (60).

To this end, as shown in FIGS. 3 and 4, the sliding fixing means 80 is fixed to the side wall of the moving block 81 and the rotating drum 30 to which the lower part of the polishing motor 50 is firmly mounted. It has a frame 82 to which the movable block 81 is slidably coupled, and an up-down screw 83 for finely adjusting the position of the movable block 81. Further, guide protrusions 81a are formed on both sides of the moving block 81 in the longitudinal direction. And the frame 82 is firmly fixed to the side wall 31 of the rotating drum 30 through the mounting bolt 85, a pair of rail groove (82a) so that the guide projection (81a) is slidably coupled Is formed. Accordingly, the moving block 81 is slidably moved in the radial direction of the rotating drum 30 along the rail groove 82a.

In addition, the up-down screw 83 is screwed to the female screw hole 82b formed in the frame 82 to move in the radial direction of the rotating drum 30 in the rotational direction. One end of the up-down screw 83 is formed with a hook frame (83a), the other end of the up-down screw (83a) is coupled to the female screw hole (82b) in a threaded manner, the outer wall of the circumferential wall (32) of the rotating drum (30) It is arranged to extend. At the end of the female screw hole 82b and the corresponding moving block 81, an idle guide 81b for engaging the idle frame 83a of the up-down screw 83 is coupled. Accordingly, when the up-down screw 83 is rotated, the moving block 81 on which the polishing motor 50 is mounted moves in the rotational radial direction. That is, in the embodiment of the present invention, when the up-down screw 83 is rotated in the forward direction (the arrow R1 direction in FIG. 4), the moving block 81 moves gradually toward the center side of the rotating drum 30 along the rail groove 82a. (See arrow F2 direction), on the other hand, when the up-down screw 83 is rotated in the reverse direction (arrow R2 direction), the moving block 81 is configured to move gradually toward the edge of the rotating drum 30 (see arrow F3 direction). . Thereby, the clearance between the grinding wheel 60 and the wire A can be adjusted suitably. In addition, in the embodiment of the present invention, the head of the up-down screw 83 is disposed to protrude outward from the circumferential wall 32 of the rotating drum 30, and is configured to be adjustable outside the rotating drum 30. Reference numeral "84" denotes a fixing nut for preventing the updown screw 83 from being arbitrarily rotated, and "13" is an opening formed on the wall of the case 10 so that the updown screw 83 can be easily adjusted.

Meanwhile, as illustrated in FIG. 5, the power supply unit 70 maintains a state where the tip of the brush 71 is in contact with the central portion of the hollow rotating shaft 20 to rotate together with the rotating drum 30. ) To supply power. To this end, the slip ring fixing member 76, which is provided so that the F-polar slip ring 74 and the L-polar slip ring 75 are spaced apart by a predetermined distance, is press-fitted on the outer circumference of the central rotating shaft 20. The F-polar slip ring The 74 and L-polar slip ring 75 are electrically connected to the polishing motors 50 through the lead wires 77. In addition, the two brushes 71 are elastically supported by the coil springs 73 in the brush holder 72 so that the front end portion is always in contact with the slip rings 74 and 75, and the rear end thereof is connected to an external power source. Connected. Accordingly, the polishing motor 50 is supplied with power through the brush 71, the slip ring 74, 75 and the lead wire 77 while rotating integrally with the rotary drum 30.

Next, the operation of the wire polishing apparatus according to the present invention configured as described above and the effects thereof will be described.

First, when the driving motor 44 is driven, its rotational force is transmitted in the order of the driving pulley 43 → belt 42 → driven pulley 41, so that the rotating drum 30 rotates integrally with the hollow rotating shaft 20. . Accordingly, the two polishing motors 50 also revolve around the wire A passing in the axial direction in the rotary drum 30.

When power is supplied to the polishing motor 50 through the power supply means 70, the polishing wheel 60 is rotated at high speed together with the rotating shaft 51 to polish the wire A surface. At this time, the abrasive 61 of the abrasive wheels 60 rubs against the surface of the wire rod A at the mutually displaced position.

Eventually, the wire rod A exits the hollow portion 23 of the hollow rotating shaft 20 while continuously being polished with the abrasive 61 of the polishing wheels 60 (in the direction of arrow F1 in FIG. 1), thereby the wire rod A The surface is uniformly ground and polished to improve surface gloss significantly. In addition, since the grinding operation proceeds while the elongated wire A is continuously moved through the hollow portion 23 of the hollow rotating shaft 20, its work productivity is further improved.

On the other hand, when the diameter of the wire rod A to be polished is different or the abrasive 61 is considerably worn out, it is necessary to adjust the gap with the wire rod A surface. The gap between the polishing wheel 60 and the wire A surface is adjusted by the up-down screw 83. That is, after the rotation of the rotating drum 30 and the polishing motor 50 is stopped, the up-down screw 83 is rotated in the direction of the arrow R1 through the opening 13 of the case 10 as shown in FIG. 4. In other words, the moving block 81 moves to the center side of the rotating drum 30 along the rail groove 82a, whereby the center of rotation of the polishing wheel 60 is also moved to the center of the rotating drum 30. On the other hand, when the up-down screw 83 is rotated in the direction of the arrow R2, the moving block 81 gradually moves along the rail groove 82a toward the edge of the rotating drum 30, thereby causing the center of rotation of the polishing wheel 60 to rotate. It is also moved outward. In this way, the center of rotation of the polishing wheel 60 is easily adjusted, so that the wire A of various diameters can be polished.

As described in detail above; According to the wire polishing apparatus according to the present invention, the surface of the wire rod is ground and polished through the polishing wheels of the polishing motor in which the revolution and the rotation are simultaneously performed in the empty rotating drum, and the wire rod exits through the inside of the rotating drum. Accordingly, the wire polishing operation is continuously performed, and there is an effect of significantly improving the strength and appearance quality of the wire, that is, surface gloss. In addition, since the wire is ground and polished, its post-treatment is easy and there is an advantage that does not cause environmental pollution.
