Staggered tooth forming tool with drill tip

Abstract

The invention particularly relates to a staggered tooth forming tool with a drill tip. The staggered tooth forming tool is characterized in that a tool handle, a cutting part and a drilling part are included; and the drilling part comprises a drill bit, a cutting edge is arranged on the end face, connected with the external circle of the drill bit, of the cutting part, and two chip discharge grooves are distributed in the external circle of the drill bit in the axial direction. The use rate of tool materials is increased, the number of tools is reduced, and tool exchange time is shortened. By means of a staggered tooth structure, high-precision contour requirements are guaranteed, and the tool containing number of a CNC tool storeroom can be reduced. By means of the assembly of multi-tooth cutting contours, the dimensional requirement of a workpiece is guaranteed, and design is more flexible. The tool handle, the cutting part and the drilling part are integrally formed, welding is not needed, manufacturing procedures are reduced, and the manufacturing difficulty of a tool complex in contour is reduced.

Description

technical field [0001] The invention relates to the field of cutting tools, in particular to a staggered-tooth forming knife with a drill tip. Background technique [0002] According to market research, there are many kinds of cutting tools used in machining centers (data milling machines), especially in the manufacture of personalized products, such as daily electronic products such as touch tablets, smart phones, navigators, etc. It is hoped that the shape of the new product will show more and more curved effects locally. Therefore, various knives that cannot process different shapes appear in the application of machining centers. [0003] Most of the existing ones are forming knives and blind hole forming drills. The shank, cutter head and drill bit of the forming knives need to be welded, and they need to be processed and ground separately, which increases the tool manufacturing process and difficulty, and increases the investment in processing equipment. Workpieces wi...

Problems solved by technology

[0003] Most of the existing ones are forming knives and blind hole forming drills. The shank, cutter head and drill bit of the forming knives need to be welded, and they need to be processed and ground separately, which increases the tool manufacturing process and difficulty, and increases the investment in processing equipment. Workpieces with very small angles and arcs have limitations; while blind hole forming drills, all components are integrated, and cannot be processed and formed in a centerless grinding machine at one time during cylindrical grinding, which also has limitations.
