The smelting iron is led out of the furnace and milled like a hole machine to close and open. It is widely adopted by a hydraulic rod or a shank rod (hereinafter referred to as a drill rod) equipped with a gold rod or a drill head at the front end. The rod is a rod or a drill that strikes and rotates. A guard is formed at the front end. The male tapping joint is screwed to the threaded rod, rod and other drilling tools. For example, in the case of a tool, even if a male screw is formed on both ends, the male screw part is screwed to the adapter, and a drill is screwed. In the method, due to drilling or adapter applied to the drill pipe, the drilling loss is very large and the crushing efficiency is low. And the part, but the blow on the drill pipe, the rock drill piston, drill rod and other damage to the bright people and so on is to develop a drill in the above drill, please read the back-note above-notes, then I, fill in page 1 4- A7 B7 V. Description of the invention (1) The present invention relates to a blast furnace [know-how] used to open the hole of the blast furnace and the mud gun (melt gun) produced by the blast furnace. In the method, the front end of a drill rod with a shank part of an air-compressed rock drill is connected with a drill body such as a sharp body whose front end is set into a sharp shape, and then the gold is crushed to break out the milling mouth. Know the screw part of the rock drill for milling openings, and use it to install drilling tools, and then install metal on the tap joint. The drill bit is installed on the rod body as the connecting rod of the drilling screw part. And connect the adapter to the tapping joint, and then connect the one end of the connecting rod to the male thread portion of the other end of the connecting rod at the same time. [The problem to be solved by the invention] Tapping joint holes, so the energy lost in the transmission process is not the energy of the blow is crushed to form the "air strike" state, so it is very large, resulting in shortened product life. In order to solve this problem, the paper size issued in this case applies the Chinese National Standard (CNS) A4 specification (210X297 mm).

Description of the invention (2) The front end part is provided with a technology for installing a female screw part of a drilling tool, and a patent application has been filed (Japanese Patent Application Laid-Open No. 10-36905). This application exemplifies a method in which male thread portions 5 la and 51b are provided on both ends of a hexagonal hollow mesh as shown in FIG. 7 as a rod body, or a male rod is formed on the entire length of the hollow round rod as shown in FIG. 8. Threaded rod body. The rod bodies 傺 are screwed onto the above-mentioned female threaded portion of the drill rod for use. Although the above-mentioned newly developed drill rod has the advantage of better transmission efficiency of striking force or rotational force when in use, a rod body composed of threaded portions is provided at both ends of the above-mentioned hexagonal hollow copper pipe or the entire hollow rod is integrated.杆 A rod body having a threaded portion in length has the problems that the material of the rod body itself is expensive, and the processing cost required to form the threaded portion is high. This type of body melts out once used, so it is not economical to use expensive rods. [Means for solving the problem] The present invention solves the above-mentioned problem of conventionally used pipes for milling and opening holes. To solve this problem, the present invention provides the following pipe body. That is, the pipe boring hole for milling and milling according to the present invention is a special cymbal with a predetermined length formed at one end of a round copper pipe having an outer diameter of 30 to 50 mm and a wall thickness of 10 mm or less. The pipe boring screw for opening the milling opening is used by being mounted on a threaded portion provided at a tip portion of a drill rod of a rock drill. The front end of the pipe body is welded with a drill bit having a hard cutting block. Different from the conventional hollow steel pipe, the inner diameter of the pipe body of the present invention is relatively large, so a drill bit that can be fitted into the pipe body using the hub portion, and the valley portion is fitted into the front end portion of the pipe body. Make it welded and fixed. Therefore, alignment is easy during welding, and high welding strength can be obtained. Moreover, since the material is a circular tube, it can be rotated to produce a male threaded portion that simply forms the end portion. -5- (Please read the precautions on the back two before ^^^ page) • The binding and binding paper size is applicable to the Chinese national standard (CNS > A4 size (210X297 mm)) Printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Manufacturing A7 B7 V. Description of the invention (3) [Embodiments of the invention] The following specifically describes one embodiment of the present invention shown in the drawings. As shown in FIG. 1 and FIG. It is assumed that a pin pipe is used as the material, and the steel pipe has a diameter much larger than that of the hollow steel rod 2 of the conventional hollow steel pipe. One end of the opening pipe 1 is formed with a male screw portion 3, and the S-end portion is a simple pipe body. The size of the pipe body 1 is 30 ~ 50ram outer diameter, and the wall thickness is 10mm or less. The length of the pipe body 1 is usually several meters, but it can also be made into appropriate length according to the conditions of use. The outer diameter of the pipe body 1 is larger than the above range When the outer diameter is smaller than the above range, the strength of the pipe itself is insufficient, and the welding strength of the drill bit is also reduced. It is difficult to be ideal. In addition, the material of the pipe body 1 is of course High-grade alloy steel such as conventional hollow steel is used, but relatively inexpensive steel (such as carbon-containing tool steel) can also be used. In addition, the above-mentioned male thread portion can be simply formed by a rotary manufacturing method. In general, all kinds of threads used in related components of drilling machines can be used, but from the perspective of simple assembly and disassembly, it is better to use so-called T-threads or composite threads. Regarding the preferred size, take specific examples, When using a pipe body with an outer diameter of 38.1mm and a pipe wall thickness of 9mm, or a pipe body with an outer diameter of 42.7mn and a pipe wall thickness of 6.4mm, it is easier to form a well-known T-thread as a male thread by rotation, and the strength is also sufficient. The drill bit 5 fixed on the opposite end of the male thread part 3 of the pipe body 1 is provided with a head 7 having a diameter larger than that of the pipe body 1, and a large number of hard blades 8 are planted on the front face of the head 7 .....

Description of the Invention (4) Section 9, the rear end of the pivot section 9 is integrally provided with a circle for socketing inside the pipe body 1. Rod-shaped hub 10. The section 10 and the trunk 9 form a section, and the rear end 9a of the trunk is a plane perpendicular to the center line. A cleaning hole 1 is formed on the center line of the drill 5. The hole 13 傺 forms a through-hole method along the centerline, and it extends diagonally forward in the middle and divides the hole (13a) which opens towards the front of the drill bit. The drill bit 5 傺 is fixed to the outlet opening by welding. With tube 1. When welding, the valley part 10 of the drill bit 5 is first sleeved on the hollow part 2 of the pipe body 1, so that the plane at the end of the trunk 9 abuts against the end face of the pipe body 1, and then along the pipe body 1 and the drill bit 1 The outer periphery of the connection part is welded. Therefore, it is preferable to make the outer diameter of the trough portion 10 approximately equal to the inner diameter of the pipe body 1 in advance. With this design, the center alignment operation during welding becomes easy, and the drill bit does not move during welding, which has the advantage of easily performing high-intensity welding. In addition, there may be cases where a threaded portion is formed in advance on the end of the drill bit of the pipe body, and the screw or drill bit is fixed by screwing. The pipe body 1 provided with the drill 5 at the front end portion is fixedly welded to the female thread portion F of the drill rod S of the drilling machine by using the male thread portion 3 at the rear end portion thereof. Since the pipe body 1 integrally welded with the drill 5 is directly connected to the drill pipe S, the impact force or rotation force of the drilling machine D can be transmitted to the drill with high efficiency, so that its breaking efficiency is very good.
