Indexable cutting blade for cutting machining of engineering rubber materials

Abstract

The invention discloses an indexable cutting blade for cutting machining of engineering rubber materials. The indexable cutting blade comprises a blade body with the projection on the horizontal planeapproximately being a square. The blade body comprises an upper surface, a lower surface and side faces surrounding the periphery, and the lower surface is a plane. A plurality of tooth-shaped protruding parts are further arranged on the side faces of the blade body in an outward extending mode, cutting edge parts are formed at the edges of the upper surfaces of the tooth-shaped protruding parts,and front blade faces of the cutting blade are constituted by the upper surfaces of the tooth-shaped protruding parts. Rear blade faces of the cutting blade are constituted by the side faces of the tooth-shaped protruding parts, and the rear blade faces each comprise at least two faces from top to bottom. According to the indexable cutting blade for cutting machining of the engineering rubber materials, when cutting machining of the elastic materials such as rubber is conducted, efficient cutting machining of the elastic materials such as the rubber can be achieved while the machined surfacequality of the rubber materials is ensured and the life of a tool are prolonged.

Description

technical field [0001] The invention relates to a cutting tool, in particular to an indexable cutting blade for cutting engineering rubber materials. Background technique [0002] With the development of science and technology, the application fields of engineering rubber materials are becoming more and more extensive. At present, they have been widely used in engineering fields such as bridge bearings and expansion devices, construction machinery, waterproof and drainage materials, and vibration isolation and vibration reduction technology. [0003] Due to the elastic characteristics of rubber materials, its cutting characteristics mainly include the following points: [0004] 1. Due to the small elastic modulus and fast elastic recovery of the rubber material, it is easy to deform during cutting, and it is difficult to control the size and shape accuracy, especially when the tool is small, it is difficult for the tool to cut into the workpiece material; [0005] 2. The ha...

Problems solved by technology

[0006] 3. The thermal conductivity of rubber material is very low, generally about 1 / 350 of that of steel

[0009] Traditional straight-edge or curved-edge cutting tools have high cutting resistance when cutting engineering rubber materials, and the heat generated is difficult to diffuse, resulting in engineering rubber being easily softened during processing, which affects the cutting performance of rubber and the quality of the machined surface.
