Since the cutter is a cutting machine, not only does the movable blade 10 and the fixed blade 20 need to be precisely aligned, but also the wear of the supporting body 1Oc and the sliding member 1Od for supporting the blade 1Ob of the movable blade 10 causes the movable blade 10 to wear. In order to cause a collision accident between the fixed blade 20 and the fixed blade 20, or to cause a gap in the movable blade 10 and the fixed blade 20 to cause a failure in shearing operation of the thin plate 40, thereby causing troubles in blade alignment. This is a break which is frequently pursued by a complicated maintenance operation of re-adjusting the support body 1Oc for supporting the movable blade 10 and the sliding member 1Od.

板切断機の開発が強く望まれていたものである。Particularly, in the above-mentioned guillotine-type thin plate cutting machine illustrated in FIG. 2, precise alignment of the movable blade 10 and the fixed blade 20 is performed by mixing glass fiber or the like into a veneer veneer in which fibers are crossed or epoxy resin. This is a serious problem in the cutting process for handling printed circuit boards and the like, for example, in a plywood factory, etc. As exemplified in FIG. 3, the cutting portions 4Oa of the thin plate 40 are connected by the whisker-like fibers 4Ob, so that the defective portions 4Oc cannot be cut and divided. This tendency occurs frequently in veneer veneers cut from low-grade logs, causing difficult situations such as significantly reducing the cutting yield and cutting efficiency. Without requiring a complicated maintenance work,
In addition, there has been a strong demand for the development of an improved thin plate cutting machine which completely eliminates the generation of whisker-like fibers which are likely to be generated at a cutting position and which is a completely new shearing method.

うになったものである。[Function] In a guillotine-type thin plate cutting machine in which a movable blade and a fixed blade are opposed to each other vertically, a thin single-blade type movable blade having a moderate elasticity of the blade body, for example, a thickness of the blade body is about 1 to 2 mm,
A single blade type movable blade having an exposed portion of the blade body of about 10 to 20 mm,
A fixed blade with the upper and lower portions of the shearing surface appropriately inclined inward and outward on the operating line of the movable blade, for example, with the upper portion of the shearing surface being drawn inward by about 0.025 mm with respect to the operating line of the movable blade, By forming a guillotine-type thin plate cutting machine by vertically matching a fixed blade whose lower part is protruded outward at an inclination angle of about 1 to 2 °, the movable blade has a lateral direction acting on the blade edge. The blade can be flexed appropriately by a stress, for example, a stress of about 6 kg, for example, and can be flexed by about 2 mm, and the fixed blade has an appropriate shear strength against the movable blade at an upper part of a shear plane facing the movable blade. Forming a non-contact area, for example, forming a non-contact area of about 0.5 mm, and forming a moderate elastic contact area with the movable blade below the non-contact area, for example, forming an elastic contact area of about 4.5 mm. Since the upper part of the shearing surface of the fixed blade has been retracted by about 0.025 mm from the working line of the movable blade, the position where the movable blade is first cut into the fixed blade is 0.1 mm. A gap of about 025 mm is formed so that a collision accident between the movable blade and the fixed blade can be eliminated beforehand,
The lower part of the shearing surface of the fixed blade is projected outward at an inclination angle of about 1 to 2 ° to form an elastic contact area of about 4.5 mm between the shearing surface of the fixed blade and the movable blade. Thereby, a beard-shaped fiber that is likely to be generated at a cutting position of a thin plate such as a veneer veneer or a printed board is pressed by an elastic contact of the movable blade with the movable blade against a shear plane of the fixed blade, that is, the movable blade is The generation of whisker-like fibers can be completely eliminated by the sliding press-off operation of the fixed blade against the shear surface of the fixed blade by elasticity. Further, the movable blade is made of carbon tool steel SK of JIS standard. By manufacturing the fixed blade from high-speed tool steel SKH material of JIS standard, even if the edge of the movable blade having the above configuration is finely chipped like a saw blade, the veneer veneer can be used as it is. Pudding The sliding push-off operation of a thin plate such as a substrate can be continued for a long time, and the shearing surface of the fixed blade having the above-mentioned structure hardly wears in material, so that it is necessary to re-grind or re-adjust it. In addition, the desired sharpness can be maintained for a long period of time without any maintenance work.
