Problems solved by technology

[0005] The technical problem to be solved by the present invention is to aim at the "self" type structure of the forming blade in the prior art, that is, the upper part protrudes in a certain arc, and the lower part is a transverse inscribed groove, which cannot achieve high-efficiency and high-precision processing To provide a high-efficiency, high-precision molding tool that not only meets the requirements for slotting of normal parts, but also meets the requirements for special processing structures for slotting.

Abstract

The invention belongs to the technical field of cutting machining, and discloses a forming machining knife. The forming machining knife comprises a knife rod and an indexable hard alloy blade, whereinthe hard alloy blade is a polygonal body and comprises an upper end surface, a lower end surface and a plurality of side surfaces; cutting units which are symmetric along the central point of the blade are arranged on the upper end surface of the blade; two grooves are formed in each of the upper end surface and the lower end surface of the blade; each cutting unit comprises a cutting edge, a front knife surface, a groove bottom arc, and a chip breaking table; each cutting edge consists of an upper end surface and side surfaces, and is divided into a plurality of sections of linear edges anda plurality of sections of arc edges; and the shape of each cutting edge is consistent to that of a cutting surface of a formed part. The knife rod comprises a clamping portion and a pressure plate; and the clamping portion is provided with a protrusion portion which is matched with the groove in the lower end surface of the blade. According to the forming machining knife, for machining of specific grooves, the difficulty of a machining process is reduced effectively, the production cost is reduced, and production quality is improved.

Description

Technical field [0001] The present invention relates to the technical field of cutting processing, and more specifically, to a tool for forming processing. Background technique [0002] At present, CNC machine tools have been widely used in the field of machining. CNC machining has the advantages of fast speed, high precision, saving labor and material costs. However, the actual application of CNC machine tools also puts forward higher requirements on cutting tools. [0003] In the actual production process, it is quite common for the groove processing of CNC machine tools, usually using ordinary shaped blade processing to achieve the effect, but in the processing of specific grooves or special structure surface, such as processing a kind of "self" type The structure, the upper part protrudes in a certain arc, and the lower part is a structure with a transverse inscribed groove. If you use ordinary shaped blades, you need to replace a variety of blades during the processing proce...
