Description

[Detailed explanation of the invention] This invention relates to a super-finishing silver plate for smoothing the wooden surfaces of architectural pillars, boards, etc.
It is made of a strip of thin steel plate at a low cost, and is designed to be extremely easy to attach to a knife holder.

As shown in Figure 1, the conventional super-finishing silver board for woodworking has a blade 4' made of high-speed steel integrally connected to the tip of the base metal of a mild steel plate, and an alloy blade made of the same mild steel plate on the back side. The back blade 5' to which the blade is connected is overlapped and fixed with bolts, and then tightened and attached to the knife stock 2 of the silver disk main body 1, and the relationship between the blade edges of the signature sword 4' and the back blade 5' is The disadvantage was that it required a great deal of time and skill to adjust the position and polish the edge of the famous sword.

In contrast, in this invention, as mentioned above, the signature sword is made of a single thin steel plate that can be used disposable without having to be re-sharpened, and the installation can be done extremely easily with one movement. As shown in Fig. 2, after attaching the signature sword 4 to the knife holder 3 in advance to the knife stock 2 which is attached to the silver disk main body 1 which has a feeding mechanism on the upper part, the knife holding plate 5 is overlapped and tightened with bolts. It is used for

Figure 3 shows a signature sword 4, which is formed by cutting one side edge of a strip-shaped thin steel plate into an inclined surface on one side to provide a sharp cutting edge 6 and a stepped portion 7 on the other end. A mounting hole 8 consisting of several elongated holes is provided.

FIG. 4 shows a state in which the signature sword 4 is clamped and fixed between the knife holder 3 and the blade holding plate 5.

That is, the blade mounting portion of the knife holder 3 is formed with a horizontal mounting surface 9 and a vertical reference surface 10 for abutting and positioning the lower surface and rear edge of the signature sword 4, and a plurality of grooves are formed in the horizontal mounting surface 9. 11, and a blade traction tool 12, which is a piano wire or the like bent in advance into a planar U-shape and both ends thereof bent upward, is attached to the groove. It is formed so that it can freely move back and forth via an eccentric shaft 13 that is rotatably loosely fitted with its upper half exposed.

In the embodiment shown in FIG. 5, this blade traction tool 12 is formed of a traction tool main body 14, which is a metal plate having a through hole at its base end and whose tip is bent upward, and a spring 15 to press down the main body 14. There is.

This invention has the above-mentioned structure, and the signature sword 4 is placed on the knife holder 3, and the bent tip of the blade traction tool 12 is engaged with the long mounting hole 8 of the knife holder 3. After positioning, by rotating the eccentric shaft 13..., the proximal edge of the sword hits the vertical reference plane 10 and is fixed therein, and then the blade retaining plate 5 is overlapped and tightened with the bolt 16. It is fixed in one piece.

17 is a positioning pin. As mentioned above, this invention is extremely advantageous because it does not require resharpening or position adjustment of the sword, and it can always be easily mounted with exact precision.

Claims (1)

[Scope of utility model registration request] This is a device in which a disposable sword 4 having a sharp cutting edge formed on the end face of a rectangular thin steel plate is superimposed on a knife holder 3 connected to a silver disc main body 1, and a knife holding plate 5 is superimposed on this and fixed by mutually tightening bolts. The signature sword 4 has a cutting edge whose width is parallel to the rear end surface of the blade, and a plurality of mounting holes 8 at predetermined intervals.
The knife holder 3 has a horizontal mounting surface 9 and a vertical reference surface 10 for positioning the lower surface and rear edge of the signature knife 4, and the horizontal mounting surface 9 has a concave groove 11.
The blade traction tool 12, which consists of a traction tool main body 14 with the tip of an elastic plate bent upward in advance and a spring 15 that presses down the main body 14, is loosely fitted into the knife holder 3 with its upper half exposed. It is engaged with the eccentric shaft 13 and is mounted so as to be freely movable back and forth.
The main body 14 of the traction tool is engaged with the mounting hole 8 of the cutting blade 4 on the knife holder 3, and the proximal edge of the cutting blade is brought into contact with the vertical reference plane 10 via the eccentric shaft 13. A super-finished silver board for woodworking that is fixed in place.
