Description

[Detailed description of the invention] The present invention relates to a cutting machine for chamfering rectangular building materials such as stone, tiles, concrete blocks, bricks, etc. used as interior materials, exterior materials, flooring materials, etc. of buildings. .

For example, when constructing the exterior wall of a building using the above-mentioned stones, etc., individual stones, etc. The stones are chamfered in advance, and the necessary stones are cut to the desired length or width in order to adjust the fit of the stones. Conventionally, in order to perform such chamfering and cutting, a dedicated chamfering machine and a cutting machine were required, which caused inconvenience in transportation to the work site, etc., and two machines were required. This was extremely uneconomical as it required the operation of several machines.

This idea was made in view of the above circumstances.
The purpose is to provide a chamfering and cutting machine that can perform chamfering, machining, and cutting with one machine. This processing machine is equipped with a guide member for chamfering on one side and a guide member for cutting on the other side, and the guide member for chamfering descends in the direction approaching the circular saw surface. A slanted swash plate, and a swash plate projecting upward at right angles to the lower edge of the swash plate, supporting the workpiece together with the swash plate in an inclined state and slidingly guiding it parallel to the circular saw surface. It consists of a projecting strip, and side plates that hang down from both ends of the swash plate and hold the swash plate at a predetermined angle with respect to the table top surface, and these side plates hold the guide member at a circular saw surface. The guide member for cutting is pivotally connected to the side surface of the table via a link mechanism so that it can be moved in a direction perpendicular to the table and can be reversed and withdrawn from the table top during cutting. a caul plate disposed parallel to the circular saw surface, a guide rod installed on the side surface of the table and supporting the caul plate so as to be movable in parallel in a direction perpendicular to the circular saw surface; and a caul plate fixing means for fixing it in position.

6b to form an L-shaped cross section. A push button 25 for operating the electric motor is installed on the front side of the table 1.

Next, the operation of the chamfering/cutting machine having the above-described configuration will be explained.

First, when chamfering, guide member 5 for chamfering
is rotated upward around the pins 14, 14 at the proximal ends of the links 9, 9 from the withdrawn position shown by the dashed line in Figs. 1 and 2, to the chamfering position shown by the solid line in the figures Set to . To set this chamfering position, loosen each tightening head 13 screwed onto the screw pin 12, and with the lower edge of the swash plate 6 supported on the top surface of the table 1, press the swash plate 6. The side plates 8, 8 integrated therewith are appropriately slid in the direction orthogonal to the circular saw surface through the elongated holes 11a through which the pins 12 are inserted, and the workpiece M shown by the two-dot chain line in FIG. The swash plate 6, side plates 8, 8 and links 9, 9 are fixed to the table 1 by tightening each tightening head 13 at a desired position that can accommodate the chamfer.
Incidentally, the swash plate 6 is formed at an angle of 45 degrees with respect to the bottom portions 8a, 8a of the side plates 8, 8.
It can also be mounted at a 45° angle to the top surface. After completing the setting of the guide member 5 for chamfering in this way,
Bring the workpiece M onto the guide member 5, place the bottom surface of the workpiece M on the upper surface of the swash plate 6, and bring one side surface into contact with and support the inner surface of the protruding strip 7, Then, the circular saw 3 is rotated, and this workpiece M
While pushing along the swash plate 6 and the protruding strip 7,
One ridge corner of this workpiece M is chamfered using a circular saw 3. Once chamfering of one ridge corner is completed, the workpiece M is rotated to change its position, and other ridge corners can be appropriately chamfered in the same manner. In this embodiment, the angle of inclination of the swash plate 6 with respect to the top surface of the table 1 is set to 45 degrees.
Although the guide member 5 is chamfered at 45°,
The angle of inclination of this swash plate 6 is not limited to 45°, but also 30° and
It can be set to any desired angle such as 60°.

On the other hand, when performing the cutting process, the above-mentioned chamfering guide member 5 is rotated downward around the pin 14 as shown by the arrow in FIG. Lower the table 1 from the top surface to the withdrawn position. Then, place the workpiece M' to be cut on the top surface of the table 1, and place one end surface of it on the backing plate 1.
6, and slide the backing plate 16 on the top surface of the table 1 to adjust the cutting length (or cutting width). To set this cutting length, first tighten the fixing screw 24 to fix the guide rod 20 to the support piece 18, then loosen the fixing screw 22 and slide the slide block 21 along the guide rod 20. Move the backing plate 16 forward and backward relative to the circular saw surface to determine the approximate cutting length, then tighten the fixing screw 22 to fix the slide block 21 to the guide rod 20, and loosen the fixing screw 24 to secure the guide rod 20 to the support piece. 18, and by rotating the fine adjustment nut 23, the guide rod 20 is displaced in the axial direction to set an accurate cutting length.

As explained above, according to the present invention, the side plate of the guide member for chamfering is pivoted to the side surface of the table via the link mechanism so that the guide member can be reversed and withdrawn from the table top surface during cutting. Because they are supported and connected, the chamfering guide member can be placed on the table top surface to chamfer the workpiece, and by withdrawing the chamfering guide member from the table top surface. It is capable of cutting workpiece materials, and one processing machine can be used for both chamfering and cutting.

Further, since the chamfering guide member can be reversed from the top surface of the table and withdrawn to the lower side thereof, it does not get in the way during cutting.

Furthermore, the side surface of the guide member for chamfering is pivotally connected to the table side surface via a link mechanism so that the guide member can be moved in a direction perpendicular to the circular saw surface. By appropriately moving the chamfering guide member, the amount of chamfering of the workpiece placed thereon can be set accurately to a desired amount.
