Abstract

The invention discloses a casting machining cutter with a replaceable cutter bit, belonging to the technical field of casting and machining and aiming at providing the casting cutting machining special cutter. The cutter comprises the cutter bit, a cutter handle and a connecting rod, wherein the cutter bit is provided with cutting blades and connected with the cutter handle by adopting screw threads or top threads, and a connecting position is positioned by adopting conical degree and an end surface; and the cutter bit is connected with the connecting rod by adopting the screw threads or the top threads, and the connecting position is positioned by adopting the conical degree and the end surface. The invention is specially used for the cutting machining of a sand mould or a sand core, overcomes the defect of poor abrasion resistance of a common cutter by adopting PCD (Polycrystalline Diamond) or superhard materials, solves the problems of cutter abrasion during the casting cutting machining, also meets the requirements for machining of a slender deep hole in such a way that the total length of the cutter is increased by adopting of the connecting rod, not only prevents the machining interference, but also is flexibly disassembled, thereby meeting the requirement for the casting cutting machining of different types.

Description

technical field [0001] The patent of the invention relates to a cutting tool, in particular to a special cutting tool for mold processing with a replaceable cutting head, which belongs to the technical field of casting and mechanical processing. Background technique [0002] Casting is one of the main methods to obtain mechanical product blanks, and is an important basic process in the machinery industry. The foundry industry is an important basic industry for the development of the national economy and an important part of the manufacturing industry. With the diversification and personalization of products, the demand for single-piece and small-batch castings is increasing, especially in the product development stage, which requires short production cycles and fast update speeds. Under such background conditions, a digital rapid manufacturing method for casting molds has emerged, that is, using casting mold cutting and forming machines to directly process sand blanks to ob...
