いる。By the way, the above-described punching device has a punch attached at one end thereof to the punching position and held by one hand, and a hammer attached to the shaft by the other hand. The upper part of the shaft hits the striking body above the punch, and the impact strikes the punch into the folding plate to open a hole.The shaft has a short grip above the punch, and the upper end of the shaft (grip The upper end of the) is hit with a hammer to drive the punch into the folding plate, both of which have the advantage that they can be easily handled on the roof, but the force of sliding the hammer along the shaft and applying it to the striking receiver is Drilling work is very difficult because each of them requires different tapping power. In the case of ,, measure the hole position each time with a tape measure or ruler,
Alternatively, there is an inconvenience that it is necessary to make preliminary preparations such as measuring the hole-drilling position in advance and making a mark, and as a result, the workability is poor, and it takes about 30 seconds to drill one hole. ing.

要となる。Further, since the lever principle is utilized, the force required for drilling is not so large as described above, but the drilling device is much larger than that, so that it can be carried and moved on the roof. In addition, it is difficult to insert it from the tip side of the folding plate to position it, and after opening the hole, remove the device from the tip of the folding plate and move to the next hole opening position. There is a drawback in that setting the device for opening and moving it is a heavy labor, and the above work is dangerous because it is performed at a high place on the roof. Furthermore, since there are few young people engaged in this type of drilling work and the population is aging, it is hard work for such seniors to swing down the hammer or attach / detach the drilling device to / from the roof tip. Is. Further, in any of the punching devices described above, since the punch for punching has a pyramidal shape or a conical shape, the entire outer circumference of the punch is in contact with the workpiece (folded plate) during punching. Due to the contact resistance, an excessive force is required for the above-mentioned hole opening.

One or two are provided. Further, a width gauge indicating the distance from the reference line on the folding plate to the center of the chisel is attached to the main body so as to be adjustable. Examples of the width gauge include flexible wires and telescopic rods, which are attached to the main body so that the angle with the axis of the chisel can be adjusted wide and narrow, and the gauge moves in the axial direction. Adjustably installed. The drive system of the impact weight in the main body is that the cam is rotated by the electric motor, the piston is operated by the rotation of the cam, the piston compresses the air in the cylinder, and the compressed air causes the impact weight to move in the axial direction. A method of pushing out a chisel placed in front of the striking weight and hitting it, or a method of pushing out the striking weight in the axial direction by compressed air from a compressor and striking a chisel placed in front, etc. The hitting weight of the hitting weight per minute is about 1000 to 2500 times.

ことはない。According to the above construction, when the chisel supported by the striking weight pushed by the action of the compressed air so as to be slidable with respect to the main body is hit, the chisel is driven into the folding plate. The reaction force causes the chisel to enter the main body, but is pushed out by the striking weight that slides back and forth, and a hole is made in the folding plate by repeating this operation. The blades are radially attached to the outer circumference of the tip of the chisel, so that the hole shape of the folded plate is square. Moreover, since the blade expands the corner of the quadrangle toward the outer side in the radial direction, the quadrangular opening has a low contact resistance and can be smoothly drilled. In addition, since the width gauge is attached to the main body, the gauge is adjusted according to the hole drilling position and the tip of the gauge is aligned with the tip of the folding plate, so that the center of the chisel is the tip of the folding plate. Since it is located at a position a certain distance from, it is possible to smoothly perform a hole drilling work to a certain position. When a flexible wire is used as the width gauge, the gauge is bent along with the progress of drilling, so that there is no obstacle to the drilling work.

（図５及び図６参照）A width gauge 4 attached to the main body 1
Is a gauge for setting the center of the chisel 2 of the punching machine at a predetermined punching position. The width gauge 4 is a base portion of the side handle 1c projecting to the side of the mounting portion 1a of the main body 1. The mounting ring 4a is attached to the mounting ring 4a so as to be adjustable in rotation, and the flexible wire 4b is detachably mounted to the mounting ring 4a.
It can be fixed at any angle. or,
On the outer surface of the flexible wire 4b that is detachably attached to the attachment ring 4a, the dimension (scale) 10 between the roof tip and the hole drilling position is displayed, making it easy to adjust the gauge when changing the hole drilling position. It is formed so that it can be performed. That is, by varying the angle formed by the shaft core of the chisel 2 and the flexible wire 4b, the distance between the tip of the chisel 2 and the flexible wire 4b is adjusted to be wide or narrow, and the tip of the flexible wire 4b is adjusted. If the center of the chisel 2 is aligned with the reference line (the tip of the folded plate), the center of the chisel 2 is always located at a constant distance from the reference line. Since the gauge is the flexible wire 4b, the flexible wire 4b is pressed against the folded plate and bent as the hole is made, so that the gauge does not hinder the hole making.

The distance to the position is set by adjusting the width gauge, and then the tip of the flexible wire 4b in the width gauge 4 is aligned with the tip of the folded plate a while the drive mechanism of the main body 1 is activated. The position pointed by the tip of is the punching position. Therefore, if the tip of the chisel 2 is pressed against the folding plate a in that state, a hole is opened in the folding plate a by the vertical movement of the chisel 2 and the radial shape attached to the chisel 2 is further advanced. The blade 3 cuts the folded plate a, and the cut sides are folded back to form square holes. The completion of drilling is controlled by the depth gauge 5 mounted on the main body 1, and the time required to drill one hole is shortened to about 1/10 of the conventional one by the series of drilling operations described above.

便利である。The square hole punching machine for roofing material according to the present invention is described in claim 1.
With the configuration described in (1), the square hole can be easily opened by electric or air, and since the square hole is formed by cutting with radially arranged blades, the entire outer circumference of the conventional punch comes into contact with the workpiece. There is less resistance that acts on the chisel (tip tool) compared to the one that is drilled, and therefore drilling can be performed with a small power source (power consumption). Therefore,
Even elderly people can work safely and easily at high places on the roof. Further, with the structure according to the second aspect, it is possible to easily measure the drilling position and improve the efficiency of the drilling work. Therefore, the number of drilling holes per unit time can be greatly increased. Further, according to the structure of claim 3, the gauge for measuring the hole-drilling position is freely bent as the hole-drilling progresses, so that it does not hinder the hole-drilling.
