The blade polishing head unit 104 may include a head unit body 130, a magnet member 120, an angle adjusting unit 200, and a rotating unit 250. Except for the head unit body 110 in the blade polishing head unit 100 described with reference to FIGS. 1 to 4, the rest of the configuration may be substantially the same configuration.

As shown in FIG. 13 and FIG. 14, the magnet member 120 may rotate on the angle adjusting surface 232 by the rotating part 250. The magnet member 120 is automatically rotated by the rotating part 250 by the friction force generated between the metal object B and the metal object polishing part C. Accordingly, the blade portion of the metal object B is evenly distributed. It will be polished.

It may include a second guide bar 510 extending to (D2).

As described above, the blade polishing head units 100, 102, 104 and the blade polishing apparatus 10, 20 according to the exemplary embodiments of the present invention have the following effects.

First, the blade polishing head units 100, 102, and 104 may include angle adjusting parts 200 and 260 and rotating parts 250 and 270, so that not only the polishing angle but also the rotation angle (left and right angles) may be adjusted. As a result, fine control is possible, and the polishing performance can be further increased.

In particular, the rotations 250, 270 allow a metal object (eg, a blade) to rotate on the angle adjuster 200 or on the side 118 of the head unit body 112, thereby fixing this rotation 14, the rotation angle may be automatically adjusted by the friction force generated between the metal object and the metal object polishing part even when only the rotation is possible without fixing.

Second, by using the angle adjusting unit (200, 260), there is an advantage that can control a variety of polishing angles. The angle is adjusted and fixed through the angle adjusting hole 238 and the fixing pin 234, or the angle block 290 having various angles can be attached and detached using the tapered portion 276 to precisely control the polishing angle. .

Third, when the rotating part 270 is interposed between the angle adjusting part 260 and the head unit body 112, when the metal object B is rotated 180 degrees by the rotating part 270, the user may rotate the metal object B. The state of can be easily confirmed.

In detail, when the rotating part 270 is interposed between the angle adjusting part 260 and the head unit body 112, the user rotates the angle adjusting part 260 and the magnet member 120 together, such that the user is exposed to the metal object. There is an advantage that can be easily confirmed the polishing state of B).

Referring to FIG. 7 again, in the case of the blade polishing head unit 100 illustrated in FIGS. 1 to 4, when the metal object B is rotated 180 degrees by the rotating unit 250, the user may rotate the blade of the metal object B. FIG. It may be difficult to check the state of the, but in the case of the blade polishing head unit 102 shown in FIGS. 5 and 6 when the metal object B is rotated 180 degrees by the rotating unit 270, the angle adjusting unit 260 And as the magnet member 120 rotates together, there is an advantage that the user can easily check the state of the blade of the metal object (B).

Fourth, the moving width adjusting unit 440 may adjust the moving width (moving width) in the first direction D1 of the blade. This may control the movement width of the linear reciprocating motion by controlling the width of the rotation when converting the rotational reciprocation motion of the chain belt 420 into the linear reciprocation motion of the extension part 410.

Thereby, the movement width can be controlled, so that finer control is possible and the polishing performance of the blade polishing apparatus can be maximized.

Referring back to FIGS. 10 and 11, when the user pulls the rotation adjusting knob 444, the first moving width W1 in the first direction D1 of the extension 410 is the second moving width ( W2), the user can adjust the moving width of the metal object B to reciprocate linearly on the metal object polishing unit C. FIG.

Fifth, the metal object polishing unit C includes a plurality of grindstones, and the blade polishing head units 100 and 102 are transferred in the second direction D2 by the second direction transfer unit 500 to have various roughnesses. The grindstones can be freely selected and worked, thereby increasing work efficiency.
