Manufacturing method for cutting tool

Abstract

Provided is a manufacturing method for a cutting tool. Firstly, a cutting area used for holding cutting parts is arranged on a cutter body; then, one or more workpieces are arranged and fixed in the cutting area; and afterwards, the outer edges of the workpieces are machined to form extrusion acting parts. According to the manufacturing method, the prefabricated workpieces (blade blanks) each provided with two or more assembling portions are fixed to the cutting area on the cutting tool to be used as the cutting parts, the extrusion acting parts are formed directly or through slight machining, and therefore low-cost rapid producing and manufacturing of forming machining tools can be achieved, and meanwhile blades of the forming machining tools can be replaced.

Description

technical field [0001] The invention relates to a manufacturing method of a tool, in particular to a manufacturing method of a cutting tool, so as to improve the manufacturing efficiency of the cutting tool. Background technique [0002] A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. Since the vast majority of cutting tools are machine-used and basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool. However, with the development of material science, various materials have been widely used in the production and processing of products, such as engineering plastics and carbon fiber composite materials (CN203401118U). The tools can be divided into several types according to the form of the workpiece processing surface: tools for processing various outer surfaces, hole processing tools, thread processing tools, gear processing tools and cutting tools. [0003] The structure of...

Problems solved by technology

Non-standard forming welding cannot be completed by machinery, so not only the working environment of the operators is harsh, but also the production and processing process is lengthy, and quality control is very difficult. It is also necessary to desolder and re-solder the blunt blades, or even discard the knives, and the degree of reuse is low. Low, very wasteful of resources and energy

Although the indexable tool realizes the reuse and quick replacement of the blade by rotating the blade at an angle, it needs to stack multiple blades to obtain the required edge shape for forming processing, which is equal to the reduced number of cutting edges, resulting in cutting Efficiency is doubled

Especially when any one of the blades becomes blunt, it is difficult to adjust the angle of a single blade to form the desired edge shape again

In addition, each side of the blade of the indexable tool is a cutting edge, which can only play a cutting role, and cannot guide the tool to support and squeeze the polishing effect, which makes the forming tool manufactured by the indexable blade only capable of cutting for roughing
