Description

[Detailed description of the invention] The present invention is such that a safety cover provided with a cushion material at the lower end is attached so as to be movable up and down on a presser cover into which the protruding part of a rotary saw can be inserted and which can press the workpiece to be cut by the rotary saw. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cutting device that can prevent an operator from touching a rotary blade during cutting operations using a rotary saw, thereby making the operation safer, will be described below with reference to the drawings.

In the figure, the cutting device 1 of the present invention includes a rotary saw 3 that is movably placed on a base 2, a presser cover 4, and a safety cover 6 with a cushioning material 5 at the lower end. It passes through a stopper 9 installed horizontally on the mounting surface γ of the workpiece W on the base 2, projects upwardly beyond the mounting surface T, and can sink below the mounting surface T.

The presser foot cover 4 is opened at the bottom and the rotary saw 3 is raised.
It has a box-like shape into which a protrusion can be inserted, and its base is inserted into a column 11 that is vertically installed on a stand-up frame 10 that is erected on the side of the base 3, and that is installed on the side of the base. guide pin 12
is inserted into the elongated hole 14 of the swing lever 13 provided in the upright frame 10, so that the presser cover 4 can move up and down as the swing lever 13 rotates.

Further, the presser cover 4 can be moved to its lowered position to press the workpiece W with its lower edge 15, and a dust collection hose 11 connected to a dust collector (not shown) for discharging chips is attached to the upper surface.

The safety cover 6 is bent in a U-shape along the presser foot cover 4,
Further, the cushion material 5 such as sponge rubber is attached to the lower end over its entire length, and the safety cover 6 is fixed to a horizontal piece 19 protruding from the front side of the presser cover 4 with the rod facing downward. It is connected to the cylinder 20 and can move up and down.

Also, on the side of the safety cover 6, there is a guide plate 2 for the presser cover 4.
2 is attached, and the safety cover 6 extends beyond the lower edge 15 of the presser cover 4 so that the safety cover 6 extends below the lower edge 15 of the presser cover 4. It is structured in such a way that it descends to the top.

Then, the device 1 of the present invention is pressed, the workpiece W is positioned by the positioning piece 25, and placed on the mounting surface γ.

When the device 1 is then operated, the cylinder 20 is lowered one step and the cushion material 5 hides the slit 9.

The compressed air in the cylinder 20 is then released.

Therefore, the cylinder 20 is relaxed, and when a hand is caught on the lower surface of the cushion material 5, the hand can be removed.

Simultaneously with the release of compressed air from the cylinder 20, the presser cover 4 is lowered by the rotation of the swing lever 13, and its lower edge 15
Press the workpiece W with .

Further, the rotary saw 3 rises while rotating beyond the slit 9 to cut the workpiece W.

The chips are discharged from the dust collection hose 1γ.

When the button cutting is completed, the rotary saw 3 descends and the presser cover 4 is pulled up by the swing lever 13.

As described above, the device of the present invention has a rotary saw that can be raised and lowered mounted on a base, and prior to lowering the presser foot cover that can press the workpiece, a cushioning material is provided at the lower end that can shield the protruding part of the rotary saw. Due to the safety cover provided, the operator cannot insert his/her hand into the cutting area when the rotary saw is raised, thus ensuring the safety of the work.

Further, the safety cover is provided with a cushion material at the lower end, so that even if a hand is stuck in the safety cover, the hand will not be damaged and can be easily removed.

Furthermore, the presser foot cover safely covers the rotary saw during cutting, thereby providing excellent effects such as increasing safety.

Claims (1)

[Scope of utility model registration request] The base is provided with a rotary saw which can be raised and lowered and which can protrude upward beyond the mounting surface of the workpiece, and the lower edge of the base is mounted such that it can be raised and lowered and into which the protrusion of the rotary saw can be inserted. The presser cover that can press the workpiece with the presser cover is capable of descending beyond the lower edge of the presser cover in advance of the lowering of the presser cover, and a cushioning material is provided at the lower end of the presser cover, thereby eliminating the need to pinch the workpiece with the lower surface of the cushioning material. A cutting device with a removable safety cover attached so that it can move up and down using a cylinder.
