るようにしたものではない。(Prior Art) A replaceable knife stock using a disposable blade that replaces a conventional planer blade is disclosed in Japanese Utility Model Publication No. 1767/1982 and Japanese Patent Application Laid-open No. 11201/1983. The former type of knife stock has a thin replacement blade with multiple mounting holes parallel to the blade edge, and can be fixed with a plane blade-shaped knife holder without a blade, a back blade-shaped knife holder, and screws. The knife holder has a recess on the mounting surface for fitting the replacement blade to the tip edge, and a blade traction device (pin member) that fits into the above-mentioned mounting hole of the replacement blade. After fitting the knife traction tool into the hole, fix the holder to the knife holding plate to sandwich the spare blade, and then attach the fixing body of the knife holding plate and knife holder to the inclined mounting surface that corresponds to the blade opening of the knife stock body. The knife holder, which corresponds to the replaceable blade holding plate of the present invention, is not directly attached to the above-mentioned inclined mounting surface, nor is it designed to be able to move slightly up and down while it is attached.

段がない。 The latter is fixed immovably to the lower arm of the knife stock body with a screw, and is provided with a knife holder having a pin member protruding from the blade mounting surface which is recessed at an oblique angle at the tip, and the blade mounting surface A replaceable blade is fitted into the replaceable blade, a long mounting hole formed in the replaceable blade is fitted into a pin member, and the replaceable blade is clamped by a replaceable blade holding plate that is attached to the knife stock such as the arm. , the upper surface of the holding plate is the material feeding surface, but since the cutter holder is fixed to the arm with screws as described above and cannot be moved, the holder cannot be moved up or down depending on the wood quality of the processed material. Not only can the blade not be moved and used, but even if superalloy is used at the tip of the holder that supports the blade, it is inevitable that the tip will wear out. If you correct it by polishing it, the area that receives the replacement blade will decrease and the cutting edge will protrude relatively, so there is no other option but to replace it.

解決点を見出すことを問題点としたものである。(Problem that the invention aims to solve) Since the replacement blade must be made as thin as 1.5 to 2.0 mm to reduce the unit price as much as possible, the configuration must be adapted accordingly. To do this, it is necessary to provide a mounting hole etc. in the replaceable blade itself to prevent it from being oversized. When the wood hardness of the workpiece is high, move the blade holding plate that receives the replaceable blade upward, and when it is soft, move the holding plate up and down to change the cutting resistance.
Otherwise, it must be ensured that no adverse effects occur. Since the knife stock that includes the blade retainer plate is used semi-permanently, there are many problems such as making it possible to continue using it by polishing it even if the tip edge of the blade retainer plate is worn away by shavings, etc. There are conditions. The problem of this invention is to find a solution that can satisfy these various points.

Move the plate 31 upward to make the protrusion of the spare blade a about 0.2 to 0.3 mm from the upper edge. If the wood is soft, move the plate 31 downward to reduce the protrusion by 0.3 mm.
The cutting resistance is changed to approximately 0.4 mm to prevent roughness of the cutting surface and occurrence of reverse marks.When the upper edge of the plate 31 is worn away by cutting chips, it is polished and moved upward to the same level as when it was first used. However, in that case, insert a screwdriver, hexagonal bar, etc. into the operating part 46 of the adjustment screw 44 and rotate it, rotate the eccentric collar 45 within the oval hole 33, and push the upper edge of the oval hole 33 with the eccentric collar 45. Even if the tip edge of the holding plate 31 is polished and corrected in order to cope with the inevitable wear, the above-mentioned vertical movement can be easily carried out, so that the replaceable blade a can be moved to a predetermined position on the underside of the holding plate 31. By moving the blade, you can always clamp the blade in the same way, and there is no need to replace it. To move the replacement blade holding plate 31 up and down by rotating the adjustment screw, loosen the mounting screw 41 and allow slight movement up and down through the screw through hole 32, which has a larger diameter than the mounting screw 41. .

Loosen the tightening of the mounting screw 41 that tightens the replaceable blade retainer plate 31 by passing it through the screw hole 32 having a diameter larger than the mounting screw 41 in the replaceable blade retainer plate 31 to be attached, and open the concave stepped surface 25.
After replacing the replaceable blade a, the replaceable blade holding plate 31 is tightened and fixed to the mounting surface 24 using the mounting screw 41, thereby facilitating the replacement of the replaceable blade a and the clamping of a new replaceable blade a. In addition to being effective, loosen the mounting screw 41 slightly to the extent that the spare blade a does not fall off.
The adjusting screw 44, which has an eccentric flange 45 located in an oval hole 33 formed in the replacement blade holding plate 31 and screwed onto the inclined blade mounting surface, is rotated by a small angle, and the eccentric flange 45 moves the replacement blade holding plate 31 upward or downward. By slightly moving downward, the degree of protrusion of the cutting edge of the replaceable blade a from the replaceable blade holding plate can be easily adjusted to suit the hardness and softness of the wood to be cut. This has the effect of being able to respond to cutting corrections.
