Bearing-combination tungsten-steel profile cutter and processing method thereof

Abstract

The invention relates to the technical field of cutters, in particular to a bearing-combination tungsten-steel profile cutter. The cutter comprises a cutter rod, a cutter head, a first bearing and a second bearing, wherein the cutter head is integrated with the cutter rod, and the cutter rod is of a cylinder structure and composed of a first connecting rod and a second connecting rod which are separated by the cutter head; the first bearing is connected to the first connecting rod, the second bearing is connected to the second connecting rod, and the second beating is close to the cutter head. According to the bearing-combination tungsten-steel profile cutter, by adding the first bearing and the second bearing for locating, the time for cutter aligning is shortened, and therefore the cutter is more flexible, high in practicability and simple to operate. Additionally, the invention also discloses a processing method of the bearing-combination tungsten-steel profile cutter.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a bearing combined tungsten steel forming cutting tool and a processing method thereof. Background technique [0002] In the process of mechanical processing, it is often encountered that there are two places with the same shape but axial symmetry on the same part that need to be processed. The traditional method of processing such places: first, it needs to be processed in two processing steps, This not only increases the processing cost, but also makes it extremely difficult to meet the processing accuracy of the two processes; the second is to use a combination of several knives for processing, and such a combination of knives cannot meet the processing requirements when processing the sharp inflection points between the blades. The accuracy, and such a combined knife cannot be made into a close-toothed tool during production, that is, the number of teeth of the tool is ...

[0002] In the process of mechanical processing, it is often encountered that there are two places with the same shape but axial symmetry on the same part that need to be processed. The traditional method of processing such places: first, it needs to be processed in two processing steps, This not only increases the processing cost, but also makes it extremely difficult to meet the processing accuracy of the two processes; the second is to use a combination of several knives for processing, and such a combination of knives cannot meet the processing requirements when processing the sharp inflection points between the blades. accuracy, and such a combined knife cannot be made into a close-toothed tool during manufacturing, that is, the number of teeth of the tool is small, which shortens the service life of the tool

[0003] At present, tungsten steel forming knives and tungsten steel double-sided milling forming knives are generally used to process the above parts, but tungsten steel forming knives and tungsten steel double-sided forming knives have the following disadvantages: the processing performance of tungsten steel forming knives is single, and the processing accuracy is difficult to guarantee. The tungsten steel double-sided forming knife has poor chip performance, the overall structure of the knife body is not perfect, and the steel of the knife body is poor, etc.

[0004] Specifically, when processing the flat forming surface, the existing cutting tools used in the processing of the flat forming surface have poor positioning, require many milling machine tool positions, increase the processing cost, complicate the process, and the overall service life is not very stable.
