Multipurpose thermal upsetting die cutter

Abstract

The invention relates to a multipurpose thermal upsetting die cutter which comprises a high speed steel cutter body. The multipurpose thermal upsetting die cutter is characterized in that two ends of the cutter body are respectively provided with a high speed steel cutter head and a hard alloy cutter head which is embedded in the cutter body and in interference fit with the cutter body, and the high speed steel cutter head is integrally formed with the cutter body. The multipurpose thermal upsetting die cutter has the advantages that the end portions of the cutter body are respectively provided with the high speed steel cutter head and the hard alloy cutter head, the corresponding cutter head is adopted according to different machining portions, and the problem that cost is high when the alloy cutter head is exclusively used for machining is solved. If the alloy cutter head is abraded, the alloy cutter head only needs to be detached and replaced, the whole cutter body does not need to be replaced, and waste of resources is avoided.

Description

technical field [0001] The invention relates to a cutting knife, in particular to a multi-purpose hot heading mold cutting knife. Background technique [0002] The hot upsetting die cutter is used for cutting the hot upsetting die. The cutting edge of the current hot upsetting die cutter is directly processed on the cutter body. The disadvantage of this structure is: the current cutter material is mainly high-speed steel and hard alloy , using high-speed steel cutters for hot heading mold processing, the cutter head is easy to wear and needs to be replaced frequently, and if the hard alloy cutter with high hardness and good wear resistance is used, the cutter head wear needs to be replaced as a whole, and the use cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hot heading die cutter with low use cost and long service life. [0004] In order to solve the above-mentioned technical problems, the tec...
