Description

Woodworking finishing tool

This creation is about a woodworking dressing tool, especially a woodworking dressing tool used to trim corners.

Generally, woodwork first passes through rough wood boards, etc., and the edges often have raw edge wood chips. Or, if the wood skin is attached to the furniture, the remaining material is often left at the edge. In this case, the tool needs to be trimmed to a flat and right angle. .

As disclosed in the prior art, as disclosed in TWM309492, a blade having a right angle is matched with a blade body to abut the edge of the wood to be trimmed and pushed along the edge of the board to achieve a leveling effect, but a blade having a right angle cannot effectively The corners of the right angle of the board are trimmed and flat, and the right angle of the blade is easily changed after the blade is worn, and the effect is even worse.

As disclosed in the techniques of TW560409, TWM375598, etc., a cutter body is used to cooperate with a blade having a right angle, and the V-shaped corner of the corner of the end is used to increase the effective contact surface of the trimming edge, so that the efficiency of trimming is increased, but due to the cutter The angled groove of the body is at right angles to the blade, which is easy to work with and rubs against the surface of the board to reduce the effect. If the corner groove is not rubbed against the surface of the board, it needs to be additionally processed to form a concave groove to prevent friction and manufacture. It is more complicated and difficult. In addition, the TWM375598 has a recessed area at the blade device, and even a cassette portion is provided to fix the blade, which greatly increases the cost and difficulty of production.

In addition, the blades disclosed in the above three cases are directly bonded and fixed to the tool holder. In fact, when the blade is worn repeatedly after repeated use, it can not even protrude beyond the cutter body. This dressing tool is equivalent to invalid, and needs to be replaced with another new product, which is not in consideration of environmental protection and economy.

This creation provides a woodworking dressing tool that allows the user to trim the edges of the wood more efficiently and to improve the bluntness of the knife.

The woodworking dressing tool comprises a cutter body and two ceramic blades, the cutter body has a corner groove, the corner groove has two angled faces, and the two angle masks have an angle greater than 90 degrees, and each blade is L The glyphs are respectively disposed at two ends of the cornering groove, and one of the surfaces of the blades corresponds to the corner groove and is fixedly connected with the corner groove, and the opposite surface angle is a right angle, and the blades are respectively The corner corners of the corner groove have corresponding V-shaped cutting edges and notches, and each of the blades is screwed on the cornering surface.

As a result, the finishing work will be more efficient, the manufacturing will be simpler and cost-effective, and the blade replacement and replacement will be more environmentally friendly and economical.

Figure 3 is a side view of the creation.

In the following, the preferred embodiments of the present invention will be described in the preferred embodiments, but are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 3, the present invention provides a woodworking dressing tool comprising a cutter body 1 and two blades 2.

The cutter body 1 has a corner groove 11 on one side thereof, and the corner groove 11 includes The two corner surfaces 111 and 112 are integrally formed by the two angled surfaces 111 and 112. The width of the angled surface 111 is smaller than the width of the angled surface 112, and the angles of the two angled surfaces 111 and 112 are opposite. More than 90 degrees, a corner of each of the two corner faces 111, 112 is provided with a V-shaped notch 113, and each of the notches 113 is not parallel to the end edges of the two corner faces 111, 112 and is inclined to the second The end surface of the corner surface 111, 112, the cutter body 1 is opposite to one side of the corner groove 11 and has a grip portion 12, and the grip portion 12 has a concave grip groove 121 for use. The holder is stable.

Each of the blades 2 is L-shaped and made of ceramic material, and the two blades 2 are respectively The blade 2 includes an upper cutting edge 21 and a lower cutting edge 22, and the upper cutting edge 21 is in contact with the lower cutting edge 22 and is not parallel. Each of the upper cutting edges 21 has a first surface and The second surface, each of the lower cutting edges 22 has a third surface and a fourth surface, each of the first surfaces is in contact with the smaller angled surface 112, and each of the third surfaces has a larger angle The surface 111 is fixed in contact, in other words, the angle between each of the first surface and each of the third surfaces corresponds to the angle between the corner grooves 11, and the length of each upper blade 21 corresponds to the width of the angled surface 112. The length of each lower blade 22 corresponds to the width of the corner surface 111; and the angle between each of the second faces and each of the fourth faces is a right angle. In addition, each of the blades 2 is aligned with the edge of the corner groove 11. The end corners of the upper cutting edge 21 and the lower cutting edges 22 have a V-shaped cutting edge 23, and each of the cutting edges 23 is associated with each of the notches. 113 corresponds to each other, and the surface of each of the cutting edges 23 is not perpendicular to the first surface and the third surface, that is, the cutting edge 23 is inclined to the edge of the blade 2.

In the preferred embodiment of the present invention, each of the blades 2 and at least one of the cornering faces 111, 112 has at least one screw hole, so that each of the blades 2 is screwed to the corner groove 111 by a screw, so that the new blade can be replaced. Preferably, the screw holes on each blade 2 can be elliptical. So that the position of each blade 2 can be moved in the direction in which the corner groove 11 extends, when the blade 2 is worn out, The screw can be adjusted to move the blade 2 to the outside, and can be reused to improve the service life.

When the user uses this creation to trim the edge of the wood, please refer to Figure 3, the original The corner groove 11 is in close contact with the edge 3 of the wood to be trimmed, the hand grip 12 is biased toward the edge 3 of the wood, and the creation is moved along the edge 3 of the wood, so that the blade 2 trims the edge 3 of the wood into The tidy right angle, and since the corner groove 11 of the present design is designed to be non-right angle, the portion of the corner groove 11 not provided with the blade 2 does not come into contact with the wood, thereby reducing the improper friction of the corner groove 11 and the wood. The efficiency is reduced, and the wear and tear of the creation is also avoided.

In summary, this creation has several advantages:

1. Easy to manufacture and low in cost: This creation does not need to dig a groove for preventing friction on the corner groove, and does not need to have a clamping portion for fixing the blade. The screw lock design makes assembly of the blade and the tool body simpler. The screw lock design is also less likely to fall off.

Second, the blade can be replaced: when the blade is worn, the user only needs to replace the new blade without replacing the whole dressing tool with new ones, achieving environmental protection and economic benefits.

Third, the blade can be moved: when the blade is slightly worn, the screw is adjusted to make the blade move outward, which can increase the service life of the blade.

In a nutshell, this creation has many advantages, it is practical, environmentally friendly and economical, and it has the effect of progress. It meets the patent requirements stipulated by the national patent law, and the patent application is filed according to law, so that the bureau can approve the patent as soon as possible. Will.
