Problems solved by technology

Due to the one-piece manufacturing method, although there is no difficulty in manufacturing, it can reduce some costs, but because the material must be completely made of high-speed steel, it will increase a lot of material costs.

Embodiment Construction

[0016] The preferred embodiments and technical content of the present invention are described as follows in conjunction with the accompanying drawings.

[0017] The present invention relates to a manufacturing method and structure of a drilling tool, please refer to image 3 shown, which shows the manufacturing method of the present invention, and please also refer to Figure 4 , Figure 5 ,and Image 6 , which shows the structure made according to the method of the present invention, which can quickly cut and drill hard materials such as wide edge I-shaped steel and thicker steel plates of steel structure buildings, the method includes: (301) first, First, by forging, weldable metal materials (such as: chrome-molybdenum steel, white steel, etc.) are integrally formed into the base body 4, so that the base body 4 has a shaft 41 and a cylindrical part above the shaft 42. A plurality of fitting parts 43 formed on the upper end surface of the cylindrical part 42, and a plurali...

Abstract

The invention provides a manufacturing method and a structure of a drilling tool, which includes the following steps: forging a main base leading the main base to have a chimeric department formed ona shaft body, a cylinder department and the upper end surface of a cylinder department, manufacturing a drill bit forehead in a manner of powder metallurgy to be cylinder-shaped, forming a plurality of chimeric components on the lower end corresponding to the chimeric department on the upper end surface of the main base, and forming drilling tools with the advantages of abrasion resistance and break resistance after the joint of the drill bit forehead and the main base.

Description

technical field [0001] The invention relates to a method for manufacturing a drilling tool and its structure, in particular to a drilling tool that can quickly cut and drill hard materials and has the characteristics of wear resistance and non-breakage. Background technique [0002] General traditional drilling tools such as figure 1 As shown, the drilling tool 1 is provided with a cutting bit 11 at one end, and the waste chips after drilling are carried out through the spiral groove 12 designed on the outer wall surface. Yet, the cutting bit 11 of this prior art drilling tool 1 realizes the cutting purpose with the rotation of the chisel edge 111 radially in the center; The farther chisel edge 111 needs to drill more range, on the contrary, the chisel edge 111 that is closer to its center then has less range to drill, thus often causing uneven resistance of the chisel edge 111 during drilling, and shocks are prone to occur during processing. In addition, the drilling tool...
