Three-edge tungsten steel forming tool

Abstract

The invention belongs to the field of cutting tools and in particular relates to a three-edge tungsten steel forming tool. A groove is formed in the joint of a tool neck and a knife handle, and a chamfer is formed at the joint of the tool neck and a tool bit; three cutting edges are arranged on the cutting end surface of the end part of the tool bit; openings of the three cutting edges pass through the center, and the cutting edges are smooth; the chamfer is 60 degrees; the length of a cutting part is 10mm; the diameter of the tool bit is 7mm; the diameter of the front end of the tool bit is 2mm; the length of the tool bit is 5mm; the distance from the cutting end surface to the end part of the tool bit is 0.59mm; and the tool bit is made of tungsten steel. The three-edge tungsten steel forming tool is high in milling speed on a small workpiece, and according to the three-edge tungsten steel forming tool, the machined surface is smooth, and the machining precision is improved.

Description

technical field [0001] The invention belongs to the field of cutting tools, in particular to a three-edged tungsten steel forming knife. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. At present, small parts with high precision requirements, due to Generally, if the forming knife is too large, it is often difficult to process, not only the work efficiency is low, but also the dimensional accuracy of the processing cannot be guaranteed; further, when the small parts are made of aluminum alloy with high hardness such as AL6063, the forming knife of general material not only limits the milling speed and can not guarantee a good surface smoothness; and in the process of processing, it is necessary to perform filleting or chamfering on the processed workpiece many times, usually requir...
