Description

Woodworking cutter

The present invention relates to a woodworking cutting knife, in particular to a kind of decorative skin which is cut and attached to the wooden board and protrudes from the side of the wooden board, so that a positive force can be applied during the cutting process, Will cause the decorative skin to peel or break. .

Please refer to the first, second and third figures, which are a conventional woodworking cutter for cutting the decorative leather 3 attached to the side 2 of the wooden board 1, because the decorative leather 3 must be cut into the wooden board 1 when it is laminated. The width of the side 2 of the wooden board 1 is wider than that of the side 2 of the wooden board 1 to facilitate the decorative leather, and after the fitting is completed, the excess convex decorative leather 4 is removed.

The woodworking cutter has a first body 5 having a first pressing surface 6 and a second body 7 connected to the first body 5 and having a second pressing surface 8 A pressing angle is formed between the pressing surface 6 and the second pressing surface 8, and a V-shaped cutting blade 9 is formed at one end of the first body 5 and the second body 7

When the decorative skin 4 is removed, the first pressing surface 6 of the first body 5 of the woodworking tool is pressed against the decorative skin 3 of the side 2 of the wooden board 1, and the second body 7 is second. The pressing surface 8 is pressed against the front surface 10 of the wooden board 1 and the cutter is moved. At this time, the cutting blade 9 cuts off the excess decorative leather 4, but since the cutting direction of the cutting blade 9 is at an acute angle θ1 with the tool moving direction, this At the same time, the decorative leather 3 will be subjected to an upward component A, so that during the cutting process, the decorative leather 3 will be torn by a reverse force, so as to affect the quality of the product, which is a conventional The cutting of woodworking tools is missing.

In view of the lack of the above-mentioned conventional woodworking cutting knife, the creator created the creation of a woodworking cutting knife, which can effectively improve the lack of knowledge and make it more practical.

The present invention is characterized in that it comprises a first body having a first pressing surface; a second body connected to the first body and having a second pressing surface for the first pressing surface Forming an angle with the second pressing surface; and a cutting blade formed at one end of the second body, the cutting blade surface being perpendicular to the axis connecting the first body and the second body .

If the cutting of the excess decorative skin is performed, the cutting surface of the cutting blade is at an acute angle to the cutting direction, so that the decorative skin is subjected to a component force in the direction of the side plate of the wooden board. If it is, the cutting process will generate a component. The positive force, without tearing the decorative skin upward, can have better cutting quality.

Please refer to the fourth and fifth figures for the perspective view of the woodworking tool. There is a first body and 20, a second body 22 and two cutting blades 24. The first body 20 has a flat first pressing surface 26.

The second body 22 is integrally formed with the first body 20 by a metal material, and has a second pressing surface 28 connected to the first pressing surface 26. In the embodiment, the first pressing surface 26 is The second pressing surface 28 is at a right angle.

The two cutting knives 24 can be integrally formed of a metal material or a ceramic material, and are respectively formed on the front and rear ends of the second body 22, and the cutting knives 30 and the first The connecting axis of the body 20 and the second body 22 is at an acute angle 3 and the first pressing surface 26 extends forwardly from the cutting blade 24 to form an extending portion 34.

Referring to Figures 6 and 7, the inventive woodworking cutter is used to cut the side 38 of the wooden board 36 with the decorative skin 42 of the decorative leather 40. In operation, the first body 20 is pressed against the first body 20. The face 26 and the extension 34 are pressed against the decorative skin 40 of the side 38 of the board 36, while the second pressing surface 28 of the second body 22 is pressed against the front side 41 of the board 36. At this time, when the cutter is pressed to one side, the decorative skin 40 on the side surface 38 is pressed against the second pressing surface 28, and the cutting blade 24 is connected to the first body 20 and the second body 22. It has an acute angle. Therefore, the cutting blade 30 forms an obtuse angle θ toward the cutting direction, which can generate a component B, and applies a positive force to the decorative skin 40, and at this time, the excess decorative skin 42 is made of the wooden board 36. The side surface 38 is pressed downward, so that when the decorative skin 40 is cut, the decorative skin 40 is not torn at the time of cutting, and further, since the first pressing surface 26 is extended earlier than the cutting blade 24 An extension portion 34 is pressed against the decorative skin 40 so that the decorative skin 40 is pressed against during cutting, and is less likely to cause tearing.

Specific embodiments set forth in the detailed description of the preferred embodiment , only for the ease of explaining the technical content of this creation, not limiting the creation narrowly In the embodiment, all changes made in accordance with the spirit of the present invention and the scope of the following patent application are within the scope of the present invention.
