Abstract

PURPOSE:To assure the thickness at the top end of a peripheral wall formed simultaneously with piercing by providing a projection part on the outside peripheral surface in the steam part of a tool for piercing thereby controlling the length in the axial direction of the peripheral wall. CONSTITUTION:A tool is mounted to a drill chuck 6, is driven to rotate at a high speed around a shaft and is pressed to the surface of a metallic plate 7 in the stage of piercing the plate 7. The metal in the pierced part is flowed out in the axial direction of the tool along the outside surface of the tool by the pressure for pressing and the frictional heat generated by a high speed rotation. As a result, the plate 7 is pierced and at the same time, a peripheral wall 8 is successively formed around the hole. The wall 8 is suppressed of the flow of the metal in one axial direction by the bottom surface of the projection 3 formed on the outside peripheral surface of the stem part 2, by which the axial size on the front side of the plate 7 is settled and the top end part of the wall 8 is made thick.

It is attached to a drill head that is rotated at a plateau such as m, and uses pressure and frictional heat to press against a metal plate or metal pipe to drill a VCY" hole without cutting. Metal flowing along forms a peripheral wall [0
It has certain symptoms. Therefore, the push-up of the metal plate or metal tube is achieved simultaneously with the perforation by the surrounding wall.
It can be used to connect or connect other parts by cutting threads on the peripheral wall, but in the past, it was used to control the flow along the axis of the metal tool in the hole of the metal plate or metal pipe. Because there was no means to do so, the length of the peripheral wall in the axial direction was not determined, and the thickness of the tip of the peripheral wall was thin.
When cutting the screws, I had to cut the C screw except for the tip of this peripheral wall, and sometimes I had to cut off the tip.

この形状の相似形とされている。To explain misfire 1 below, the present invention has a tapered tip whose cross section perpendicular to the axial direction has a substantially regular polygonal shape, and a columnar shaft continuous to this tip. The shaft part is characterized by having a protrusion protruding from the outer circumferential surface of the shaft part, and this protrusion suppresses the flow of the metal in the drilling part in the direction along the tool and prevents the peripheral wall from flowing. The axial dimension is controlled, and the protrusion increases the fluidity of the tip of the peripheral wall using frictional heat, making it easier to increase the wall thickness. The present invention will be described in detail based on the illustrated embodiment. FIG. 1 shows one embodiment, which includes a two-step tapered tip (1) and a continuous tip (1). The shaft part (2) and the drill chuck (
6), a flange part (5) provided between the shaft part (2) and the shaft part (4), and a flange part (5) located on the lower surface of the flange part (5) It consists of a part (2) and a protrusion (3) in contact with the outer circumferential surface,
As shown in Fig. 2(a), the protrusion (31) is formed separately from the flange (5) while the other parts are integrally formed of cemented carbide or ceramic. (9).The horizontal section of the shaft (2)] In is approximately square and drawn as a smooth curve as a whole with rounded corners, as shown in Figure 2 (b). shape, and the horizontal cross section of the tapered tip portion fil is also similar to this shape.

好な結果を得られるものである。However, when drilling a hole in a metal plate (7) or a metal plate using a lever tool, attach it to the drill chuck (6) and rotate it at high speed around the metal plate (
7). Due to this pressing pressure and the frictional heat generated by the high-speed rotation, the metal in the perforated portion flows out along the outer surface of the tool in the axial direction of the tool. As a result, as shown in Figure 3, the metal plate (7) is drilled and at the same time a peripheral wall (8) is formed around the hole, and the other peripheral wall (8) is The metal flow in one direction in the axial direction is suppressed by the lower surface of the protrusion (3) protruding from the outer circumferential surface of the portion (2).
) is determined in the axial direction on the surface side, and the thickness of the tip of the peripheral wall (8) is thick,
In particular, since the protrusion (3) is present on a part of the outer peripheral surface of the shaft (2), the protrusion can be applied while giving a large M dignity to each part of the tip of the peripheral wall (8), which has already low fluidity. Department (
3) is brought into dynamic contact with 11 to increase the fluidity again, and good results can be obtained in maintaining the thickness of the peripheral wall (8).

In the illustrated example, the number of protrusions (3) is 2.
Although there are four pieces, it is also possible to have four pieces, and the shaft part (2)
If the horizontal cross section of the tip (1) is a substantially regular polygon, it is preferable to provide three. Furthermore, the position where the protrusion (3) is provided does not have to be a corner in the horizontal cross section as shown in the example, but it can also be placed on a side as shown by the imaginary line in Figure @5. The reason why it is integrally formed with ceramic is that the protrusion (3) can be easily provided using an acid type, and it is also heat resistant, which makes it possible to rotate the seat +1i at high speed. This is to allow perforation to be performed between the intercostals.

As in the embodiment, it is made of a convex part, and a through hole (11) is provided in the stay part (4) that passes through it vertically. (The upper part of the double shaft part (2) is inserted so that it can slide freely in the axial direction, and the lock part is fitted with the screw hole (121) and the lower end abuts the upper end of the shaft part (2). 13) and the screw 9) that presses the protrusion +31 onto the shaft (2), and then move the shaft (2) up and down. (The dimension up to +l is variable. If you want to drill a hole with a constant diameter, the protruding dimension of the shaft (2) should be increased, and the inner peripheral surface of the peripheral wall (8) will be shaped by the outer peripheral surface of the shaft (2). When performing cod pinking on the inner circumferential surface of the peripheral wall (8), the protruding dimension of the shaft (2) is reduced and the tip is adjusted so that The inner peripheral surface shape of the peripheral wall (8) can be made such that the diameter of the lower end is smaller than that of the part (1) K, which is advantageous for cod pink. A groove (15) is provided on the side in contact with the shaft (2), so that the thickness of the upper end of the peripheral wall (8) can be more reliably controlled to be constant. As shown in FIG. 8(b), the shape of the protrusion (31) is such that the lower edge of the front surface in the direction of rotation (direction of the arrow in the figure) can cut the peripheral wall (8) extending to the upper surface of the metal plate (7). In this case, as shown in Figure (b), the peripheral wall (8) is formed only on the lower surface of the metal plate (7), and the peripheral wall (8) is formed on the upper surface of the metal plate (7). In any case, it is preferable that the projection (3) is provided separately from the shaft (2) and the tip (f+). protrusion(
