Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to cutting of plate materials 8!1 for cutting plate materials such as flat roof tiles and wall panels.

[Prior Art 1] Conventionally, a cutting machine for plate materials such as roof tiles is generally known in which a cutting blade is rotated at high speed by a motor to cut the plate material. In other words, the cutting machine has a motor integrated into the base of the cutting machine, and by driving this motor, the cutting blade rotates and cuts the plate material, and the power is supplied to this motor. The power source was connected to a power source such as an outlet installed indoors or outdoors via a cord drawn from the motor.

[Problem to be Solved by the Invention 1] However, in the conventional example described above, the motor that is the drive source and the base are integrated, so it is heavy and it takes time and effort to carry it. However, there was a problem in that it was particularly dangerous when moving the tiles depending on the location on the roof.

The present invention is intended to solve the above problems, and its purpose is to enable the drive source of the cutting machine to be taken from the conventionally used electric one-man, and to connect the drive source and the base. To provide a plate cutting machine which can be formed separately to be lightweight and easily carried.

[Measures Pi for Solving the Problems] In order to achieve the above object, the plate cutting machine of the present invention has a rotatable cutting blade 2 disposed on the base 1 and a bit 4 of an electric drill driver 3. A rotary engagement portion 5 that engages with the cutting blade 2 in a detachable manner is provided, and the rotation engagement portion 5 and the cutting blade 2
and are connected by a rotation transmission means 6.

[Function] By driving the electric drill driver 3, the cutting blade 2 rotates via the rotation transmission means 6, and the plate material A can be cut. In this way, the electric drill driver 3 is used as a driving source. By rotating the cutting blade 2, there is no need to provide a drive source on the base 1, the weight can be reduced, it can be easily carried, and workability can be improved.

[Example] As shown in FIG. 1, the board cutting machine includes a support leg 7 attached to the lower part of the base 1, a pair of cutting blades 2 arranged above and below at the front part of the base 1, and a cutting machine. The main body consists of an electric drill driver 3 detachably attached to a base 1 for rotating the blade 2.

At this time, 'Il! ! ! / ] type drill driver 3 is a rechargeable electric drill driver 3 that can be made cordless by photoelectric. As shown in FIG. 3, this base 1 is formed into a substantially U-shape with one end open.
A pair of upper and lower cutting blades 2 are disposed at the upper and lower ends of this open end, respectively. As shown in FIGS. 4 and 5, the cutting blade 2a located on the upper side is replaceably attached to the tip of a sleeve 10 rotatably supported by a bearing 9 on the upper casing 8 via a nut 1. By loosening the nut 1, the cutting blade holder 12 can be loosened and the cutting blade 2a can be removed. At this time, a tapered part 13 is provided at the tip of the pongee 10, and by providing the tapered part 13 in this way, the taper [
13 increases the contact area of the shaft 10 with the cutting blade holder 12, making it possible to reliably fix the cutting blade 2a together with the cutting blade holder 12, and eliminating the need for a key to fix the cutting blade 2a, which is usually fixed with a key. This is so that both can be securely fixed. 14 is an ohm wheel attached to @10. A drive shaft 16 is provided at the front of the upper casing 8 so as to be rotatable in the vertical direction on a bearing 15 and has an upwardly opened upper end.

An electric drill driver 3 is installed at the front end of the upper casing 8.
A stand 17 is provided for engaging and holding. The rotational engagement part 5 is provided with an engagement hole 5a that can detachably engage the bit 4 at the tip of the electric drill driver 3, and rotates the bit 4 of the electric drill driver 3.
The electric drill driver 3 can be held on the stand 17 while engaged with the P2i-engaging portion 5. At this time, the electric drill driver 3 is fixed to the stand 17 by inserting and holding the tip of the electric drill driver 3 into a ring-shaped holder 17a attached to the stand 17 by a fixing pole 17b. The drive shaft 16 has a rotation transmitter #9.6 (worm gear 6
a) is provided, and this worm gear 6a is connected to the above-mentioned pongee 10.
1: Connected to the provided ohm wheel 14. At this time, the cutting blade 2a rotates by the drive of the electric drill driver 3, the soil form gear 6a and the ohm wheel 14 (from which the bit 4 of the electric drill driver 3 rotates).
It is designed so that the rotation is reduced by about one-tenth of the rotation. And the electric drill driver 3 is placed on the stand 17.
At the same time, the bit 4 at the tip of the electric drill driver 3 is engaged with the rotating engagement part 5, and the bit 4 is rotated by holding the handle of the electric drill driver 3 and operating the switch. As the rotation securing portion 5 rotates, the worm gear 6a rotates, and the rotation of the ohm gear 6a rotates the form wheel 14, which in turn rotates the cutting blade 2a. Reference numeral 18 is a handle to be held when moving the base 1, and reference numeral 19 is a safety cover disposed to cover the cutting blade 2 at 2 b.

The cutting blade 2b located on the lower side is rotatably attached to a pongee 22 disposed in an inner case 21 via a cutting blade holder 23 via a bearing 20, and the inner case 21 is attached to a lower casing 24.
It is arranged so that it can move up and down freely. That is, an adjustment nut 25 is provided at the bottom of the lower casing 24, and the adjustment nut 25 is attached to the inner case 21 by rotating it. 1]! The pongee 26 moves up and down, the inner case 21 moves up and down, and the vertical position of the lower cutting blade 2b can be adjusted.

However, when cutting a plate material A such as a tile or a wall panel, the support legs 7 are installed on the installation surface and the base 1 is held in a nearly horizontal state, and as shown in Figure ttIk2, either the left or right side of the paper is cut. On the other hand, the electric drill driver 3 is rotated so that the plate material is sandwiched between the upper and lower cutting blades 2a and 2b, and the upper cutting blade 2a feeds the plate material At'' rearward while cutting it.

At this time, the rotation of the upper cutting blade 2a is decelerated by the ohm gear 6a and the worm wheel 14, so that the plate material A is cut under pressure by the upper cutting blade 2a and the lower cutting blade 2b. It is. In this way, the cutting blade 2 is rotated using the electric drill driver 3 as the drive source to cut the plate material A, so the plate material cutting machine can be made cordless, even in places where there is no power supply, such as on the roof. , easily move your plate cutting machine! I! It is possible to cut the board material by using the electric drill driver 3, and since it is cordless, there is no chance of getting caught on the cord or tripping over it while working.
Since it can be removed from the base 1, there is no need to provide a drive source to the base 1, the weight can be reduced, it can be easily carried, and workability can be improved. If the thickness of the plate material A is different, the lower cutting blade 2b is moved up and down with the adjusting nut 25 to cut the plate material A according to the thickness. By adjusting the reverse rotation, cutting conditions such as curved lines and square cuts can be adjusted.

Figure f56 shows another embodiment of the present invention, in which the cutting blade 2 is arranged parallel to the base 1. At this time, as shown in FIG. 7, the cutting blade 2 is a cutting blade 2 whose blade part is formed to be slightly longer in order to make creases 27 in the plate material A, and the upper cutting blade 2a and the lower cutting blade 2a are used as the cutting blade 2. A slight gap is formed between the blade and the blade 2b.

In other words, by providing a gap, when the upper and lower cutting blades 2 a and 2 b are passed through the plate material, lines 27 are formed on the plate material A as shown in FIG. 7. . Behind this cutting blade 2, an idrow 28 is arranged to guide the plate material A that has passed through the openings of the cutting blades 2a and 2b.
The guide roller 28 located at the rear is a separating roller 28a for bending the plate material A containing the material upward and separating it, and the guide roller 28 located at the rear is an unnecessary part removing roller 28b for bending the plate material A downward.
It is. This separation roller 28a and unnecessary part removal row 228
A tapered portion 29 is provided in each of the portions b and b. In other words,
The plate material A with the creases 27 made by the cutting blades 2 a and 2 b first passes through the separation roller 28 a and is bent upward at the tapered portion 29 of the separation roller 28 a, and then, By passing the unnecessary part removing roller 28b, it is bent downward at the tapered part 29 of the unnecessary part removing roller 28b, and this vertical bending causes the portion wL'!
- The unnecessary parts of plate A will be reliably removed from plate A.
It can be removed while cutting. Since cutting is performed by making a crease 27 and bending the plate material A along the crease 27, noise is generated due to the high speed rotation of the cutting blade, as in the case where the cutting blade is rotated at high speed to cut the plate material. Furthermore, there is no possibility that cutting waste will be generated and scattered around the cutting work area as a result of cutting the plate material.

Further, as shown in Figure 1, the cut plate material A may be separated by providing a removal guide 30, that is, the plate material A is cut as the plate material A advances in the direction of arrow A. The opening portion is guided to the left in the drawing by a removal guide 30.
