Drilling and reaming integrated drill bit

Abstract

The invention discloses a drilling and reaming integrated drill bit, and belongs to the field of drilling tools. The drilling and reaming integrated drill bit comprises a drill bit body. A material returning groove is formed in the upper end of the drill bit body. A straight edge cutting tool is arranged at the upper end of the material returning groove. A clamping handle is arranged at the upperend of the straight edge cutting tool. The drill bit body is integrated with the material returning groove, the straight edge cutting tool and the clamping handle. The drill bit body is made of alloytool steel. Hole drilling and hole reaming are conducted simultaneously, the machining time is shortened, the equipment utilization rate is improved, and the production cost is lowered. Drilling and reaming are conducted at one time, so that product quality is effectively guaranteed. The structure is simple, production and machining technology is simple, the production cost is low, and productionefficiency is high.

Description

technical field [0001] The invention relates to a drilling-reaming integrated drill bit, which belongs to the field of drilling tools. Background technique [0002] In the machining process, the process of changing the shape or performance of the workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. [0003] The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, product assembly, debugging, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production syst...

Problems solved by technology

[0005] In the drilling process, the selection of the drill bit is particularly important. Usually, it is necessary to improve the machining accuracy of the hole. When reducing the surface roughness of the hole, it is necessary to first drill the bottom hole of the processing object through the drilling tool, and then perform the fine drilling of the bottom hole through reaming. processing, time consuming
