JPH0721288Y2 - Canna for boat board cutting and chamfering - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a planer, and more particularly to a planer suitable for chamfering a board for attaching a cloth to a wall surface of a house.

[Conventional technology]

When the board is attached to the wall surface, it is cut into an appropriate size. This cutting is performed by first making a notch in the upper paper using a cutter and then cutting the folded backing paper. However, since the cutting of the board main body is notched due to this cutting, the cutting is made into a flat surface by a concave planer. The corners of the cut end are also chamfered by cutting with a V-shaped planer.

[Problems to be solved by the device]

By the way, in the above-mentioned conventional technique, two planers are required for cutting at two places, a cut end and a chamfer, so that the number of tools increases and carrying becomes troublesome. However, there is a problem in that workability is poor and work time is required.

The present invention is intended to solve the above-described problems, and the purpose thereof is to reduce the number of tools because one cutting plane can cut at two positions, the end face of the cut end and the chamfering of the corners. At the same time, it aims to provide a planer that can improve workability and shorten work time.

[Means for Solving the Problems]

The planer of the present invention is intended to achieve the above-mentioned object, and the means is a concave groove and a V
Forming grooves and forming holes in each groove,
A replaceable blade fixing portion having a step portion in a substantially V shape communicating with the hole is formed on the other surface of the plane of the planer, and the replaceable blade is placed with the base end portion along the step portion of the replaceable blade fixing portion. The blade portion is fixed so as to face the holes.

[Action]

In the planer of the present invention configured as described above, the concave groove of the canna table is pressed against the end surface of the cut end of the object to be moved up and down, whereby the unevenness of the end surface can be cut flatly. Chamfering can be performed by pressing against the corner portion of the cut body and moving up and down.

[Example of device]

An embodiment of the plane according to the present invention will be described below with reference to the drawings.

Reference numeral 1 is a rectangular planer base made of wood, hard synthetic resin, or the like, and a V-shaped groove 1b perpendicular to the concave groove 1a in the longitudinal direction of one surface.
Is formed, and obliquely formed holes 1a ₁ and 1b ₂ are formed in the concave groove 1a and the V groove 1b. In addition, a substantially V-shaped replacement blade fixing portion 1c communicating with the holes 1a ₁ and 1b _{2 in the} lateral direction is formed on the other surface of the above-mentioned planer base 1, and
A step portion 1c ₁ is formed on the spare blade fixing portion 1c.

2 is a replacement blade that can be cut to a desired length.
The base end portion on the side opposite to the blade portion is placed on the replacement blade fixing portion 1c along the step portion 1c ₁ .

When placed in this manner, the blade portion of the spare blade 2 is inserted into the holes 1a ₁ and 1
so that the face in just right protruding amount into the recessed groove 1a and V-grooves 1b than b _2.

3 is a replacement blade fixing plate that is attached from the upper surface of the replacement blade 2 to the replacement blade fixing portion 1c with a screw 4 and an adjusting screw 5, and by tightening the adjusting screw 5, the replacement blade 2 is fixed to the replacement blade fixing portion 1c. The replacement blade fixing plate 3 is prevented from being displaced laterally by the screw 4.

In the planer configured as described above, the concave groove 1a and the V groove 1b are formed in one planer stand 1, and the spare blade 2 faces each of the grooves 1a and 1b. When cutting the cut end of the cutting body, the replaceable blade 2 cuts the unevenness of the cut end by applying the concave groove 1a to the end surface of the cut end of the cut object and moving the canna table 1 up and down. When the chamfering is performed, the replaceable blade 2 cuts the corner portion of the cutting edge by moving a V groove to the corner portion of the cutting edge of the body to be moved up and down, so that the chamfering can be performed.

[Effect of device]

As described above, according to the present invention, the concave groove and the V groove are formed on the canna table, and the replacement blades face the respective grooves, so that the cutting surface of the cut end of the object to be cut and the chamfering can be cut with one canna. This allows the operator to reduce the number of tools by one when going back and forth between the site and home, which makes transportation easier and
Since there is no need to change tools, the work is easy and the workability can be improved.
