An indexable cutting blade for cutting engineering rubber materials

Abstract

The invention discloses an indexable cutting blade for cutting and processing engineering rubber materials, which comprises a blade body projected in a substantially square shape on a horizontal plane. The surface is flat; on the side of the blade body, there are also a plurality of tooth-shaped convex parts extending outward, the edge of the upper surface of the tooth-shaped convex part forms the cutting edge, and the upper surface of the tooth-shaped convex part constitutes the rake face of the cutting blade , the side surface of the tooth-shaped convex portion constitutes the flank of the cutting insert, and the flank is at least two faces from top to bottom. When cutting elastic materials such as rubber, the invention can realize efficient cutting of elastic materials such as rubber while ensuring the processed surface quality of rubber materials and improving tool life.

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.
