Description

[Detailed Description of the Invention] The present invention relates to a knife stock used for cutting wood in woodworking, construction, etc.

Knife stocks conventionally used for wood cutting in the woodworking and construction industries, etc., have a knife stock body 1 with a blade base 2 and a blade 3 corresponding to the blade base 2, as shown in Figure 1 of the drawing. The knife stock main body 1 was inserted into and removed from the notch 5 of the table 4 of the cutting device, so in the case of a large-sized cutting device, the weight of the knife stock would be several tens of kilograms or more, so it was difficult for female workers to insert and remove it. There was an inconvenience that I couldn't do it.

The present invention has been made to solve this drawback.The purpose of the present invention is to separate the knife mounting part from the knife stock body, reduce the weight of the part to be inserted and removed, and provide a knife stock that can be easily inserted and removed even by female workers. The purpose is

Next, an example of a knife stock for cutting wood according to the present invention will be explained based on the drawings.

In Figures 2 to 5 of the drawings, reference numeral 6 denotes a knife stock body, which is removably fitted into a recessed groove 8 provided in the blade mounting portion of a table 7 of a super-finishing planer, etc., as shown in Figure 2 of the drawings. The knife stock body 6 is preferably made of a light alloy to reduce its weight.
A blade cap 9 is attached, and on the rear side of the blade cap 9,
A groove 10 parallel to the blade base 9 is formed from above.

Reference numeral 11 denotes a blade attachment part that is inserted into and removed from the groove 10 described above, and a blade attachment surface 12 with a predetermined inclination angle is provided on the side corresponding to the blade base 9, and a blade 14 with a back blade 13 attached to this attachment surface 12 is provided. , attached by a bolt 16 equipped with a cushion member 15, and this cutter 14
A wedge rod 18 that is moved forward and backward by a feed screw 17 is engaged with the lower side of the bolt 16, and this wedge rod 1
By changing the mounting angle of the cutter 14 by advancing and retreating the blade 8,
In addition to adjusting the protrusion of the blade edge, nuts 19, 19 are provided on both the left and right sides of the knife stock body 6 so as to sandwich the back blade 13, and these nuts 19, 19 are fitted with flange metals 20, 20. The adjusting screws 22, 22 engaged with the notches 21, 21 of the back blade 13 are screwed together, and the rotation of the adjusting screws 22, 22 causes the adjusting screws 22, 22 to move forward and backward, thereby engaging the notches 21, 21. The flange metals 20, 20 that have been moved also move back and forth, thereby moving the back blade 13, and the blade 14 is adjusted to be moved in and out together with the back blade 13.
Reference numeral 23 denotes a guide attached to the lower part of the groove 10 in parallel with the blade base 9. A notch 24 provided at the lower edge of the blade attachment part 11 is engaged with this guide 23, and the blade attachment part 11 is attached to the guide 23. When the blade is inserted into and removed from the groove 10, the mounting part 11 moves parallel to the blade 9 to prevent contact between the blade 14 and the blade 9.

In FIGS. 2 and 4 of the drawings, reference numerals 25 and 25 denote holes that are drilled in the portions corresponding to both corners of the front edge of the blade attachment portion 11 of the knife stock main body 6, into which stop pins 26 and 26 are fitted, respectively. 25,2
5 communicates the operating plunger 27 with an oil hole 28 that is tightly fitted at one end, and when the operating plunger 27 pressurizes the oil in the oil hole 28, the stop pins 26, 26 move into the recesses a, a
When the cutter attachment part 11 is fixed to the knife stock main body 6 and the oil in the oil hole 28 is depressurized, the stop pins 26, 26 are removed from the recesses a, a,
Only the blade attachment part 11 can be removed from the knife stock 7.

In FIG. 5 of the drawing, A is the blade attachment part 1 described above.
This is a jig for attaching the cutter 14 to the holder 1. A recess 31 is provided on the inclined base 30 supported by the stand 29 to place the mounting part 11, and a positioning piece 32 that hits the front edge of the mounting part 11 is provided on the higher side of the recess 31. and a positioning piece 33 against which the cutting edge of the cutter 14 is placed, and a push screw 35 that presses the front edge of the mounting part 11 against the positioning piece 32 is screwed into the support piece 34 of the lower mounting part 11. An adjustment screw 37 that is finely moved by a fine movement device 36 supported by the inclined base 30 is screwed into the positioning piece 33 for the cutter 14 described above.

Next, the operation of the knife stock shown in the above embodiment will be explained.

Place the blade attachment part 11 in the recess 31 of the inclined table 30 in the jig A as shown in FIG. A cutter 14 with a back edge 13 is placed on the blade 12, and is slid toward the positioning piece 33, and when the edge of the blade hits it, it stops and the tip of the blade is determined. Therefore, the cutter 14 and the back blade 13 are fixed to the mounting portion 11 with bolts 16.

Next, loosen the push screw 35 and cutter attachment part 11.
is removed from jig A, and as shown in FIG. When inserted, the mounting portion 11 is guided by the guide 23 and is housed in the knife stock body 6 without causing contact between the blade 14 and the blade base 9.

Once the blade attachment part 11 is housed in the knife stock body 6 in this way, when the operation plunger 27 is operated to pressurize the oil in the oil hole 28, the oil moves the stop pins 26, 26 into the recess a of the blade attachment part 11,
a to fix the attachment part 11 to the knife stock body 6, the blade attachment part 11 is integrated with the knife stock body 6, and the blade 14 protrudes above the table 7 by the desired cutting allowance. Cutting of the material that is sent to the machine will be carried out.

In addition, this knife stock can be used to operate the operating plunger 2 if the blade 14 becomes unable to cut due to cutting of the material.
7 in the opposite direction to the above to remove the pressure from the oil in the oil hole 28, the stop pins 26, 2 will come out from the recesses a, a.
6 can be removed and only the blade attachment part 11 can be pulled out. In this case, the blade attachment part 11 is guided by the guide 23 so that the blade 14 and the blade base 9 do not come into contact with each other. be.

As mentioned above, the knife stock related to this invention is
The knife mounting part is separated from the knife stock body, and the knife stock body is placed on the table side, and only the knife mounting part is inserted and removed, so the weight of the part to be inserted and removed is light, and even female workers can easily remove it. It is possible to insert and remove the blade, and since the insertion and removal operations are guided by a guide to prevent contact between the blade and the blade base, there is no possibility that the blade will hit the blade base and cause the blade to be crushed or chipped. In addition, the installation of the blade to the blade mounting part is
A jig is used to accurately determine the position relative to the blade mouthpiece, so you can simply fit the blade mounting part into the knife stock body after installation, and the blade extension can be set accurately without the need for correction. It has the unique effect of being able to obtain a cutting effect.
