に装備されるチツプの形状に関するものである。[Detailed description of the invention] Industrial application field The present invention relates to a plasma cutting torch that performs cutting by bringing the tip end surface into contact with a base material, and specifically relates to the shape of the tip installed in the torch. .

る。BACKGROUND ART AND PROBLEMS Generally, this type of plasma cutting torch is comprised of a torch body 1, a shield cup 2, a tip 3, an electrode 4, etc., as shown in FIG. Then, a plasma arc 6 is generated between the electrode 4 and the base material 5 to cut the base material 5. At this time,
For example, compressed air is used as the working gas 7 and the cooling gas 8. Then, the working gas 7 is supplied to the tip hole 3a.
The cooling gas 8 is ejected through the space between the shield cup 2 and the chip 3. Note that 9 is a torch handle, and 10 is a torch switch.

不具合である。 Conventionally, a tip shown at 32 in FIG. 3 has been used as a tip for this plasma cutting torch. In FIG. 3, 32a is a tip hole through which the working gas 7 is ejected, 32b is a hollow portion in which the electrode 5 is placed, and 32c is a threaded portion connected to the torch body 1. Further, 32d is a knurled portion for preventing slipping when tightening the screw. Furthermore, its tip is spherical. Cutting is performed while the tip of the plasma cutting torch, that is, the tip of the tip 32, is brought into contact with the base material 5 and is slid thereon.At this time, cutting is often performed along a ruler or the like. However, since the tip of the tip 32 is spherical, it is difficult to fit it along the right angle surface of the ruler.

る。Purpose of the invention The purpose of the invention is to provide a so-called touch-type plasma cutting torch that cuts by bringing the tip end surface of the tip into contact with the base material. The shape of the chip was taken into consideration so that it could be easily adapted to this.

る。 The tip 31 has a tip hole 31a for blowing out the working gas 7, a hollow part 31b for disposing the electrode 4 in a floating state, a threaded part 31c for connecting to the torch body 1, etc., as in the conventional example. It is provided. However, the outer shape of the tip end of the tip 31 is different from the spherical shape of the conventional example, and has a special shape. Since this is the main part of the present invention, its details will be described next.

mm以上とする。 At the tip of the tip 31, a disc-shaped part A and a truncated conical part B are provided on the same axis and connected to the disc-shaped part A. Therefore, its outer shape becomes a shape that expands in a tapered shape from the disk-shaped portion A through the stepped portion 31e. The disc-shaped part A has a diameter d 1 of 6 to 7 mm and a thickness t 1
is set to 1.5 to 2 mm, and the tip radius is set to 0.5 to 1 mm. In addition, the truncated conical portion B has a head diameter d 2 of 8
mm or more.

ーパ角とあいまつて定まるものである。なお、３
１ｄは既に説明を加えたローレツト部である。 Next, we will discuss the reason for limiting the numerical range of each part. It is desirable that the diameter d 1 of the disc-shaped part A is as small as possible in order to accurately follow the scribing line. If it is less than 6 mm, the torch may shift from the end of the base material 5 at the start of cutting. It has poor workability, and problems such as seizure occur due to insufficient cooling of the tip contact area. Thickness t 1
is the thickness t 2 of the commercially available ruler 11 shown in Figure 2B.
However, since the maximum value is 1.5 mm (for a metal ruler with a length of 100 cm), it is set to 1.5 mm or more, and the thickness t is set to 2 mm because it is easier to align it with the ruler 11 if it is as small as possible. Also, the tip radius R is
The width is set to 0.5 to 1 mm so that the corner of the tip 31 does not get caught on the base material 5 or the ruler 11 and does not come off the ruler 11 when the torch is moved along the ruler 11. The diameter of the head of the truncated conical part B is such that the width of the stepped part 31e is at least 1 mm.
As mentioned above, it is preferably about 2 mm, so it is set to 8 mm or more. There is no particular restriction on this upper limit, but if the thickness of the chip 31 is considered, it will naturally be determined in conjunction with its taper angle. In addition, 3
1d is the knurling portion which has already been explained.

状を勘案し、これをトーチに適用したものであ
る。 As mentioned above, the plasma cutting torch of the present invention takes into account a suitable tip shape and applies it to the torch so that it can be easily traced using a commercially available ruler. This is what I did.
