Problems solved by technology

[0006] Based on the existing technical problems that the temperature of the existing grinding wheel will rise after cutting the rail for a long time, it will become soft and cannot continue cutting, and it will cause a lot of waste after use. This invention proposes a cutting grinding wheel for rail transportation.

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0041] refer to Figure 1-4 , a cutting wheel for rail transit, comprising a basic abrasive composed of phenolic resin powder, corundum abrasive and silicon carbide abrasive;

[0042] The inside of the basic abrasive is also provided with cemented carbide abrasive and graphene abrasive.

[0043] Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has a high hardness at 1000 °C, and it is applied to the cutting grinding wheel, which ...

Abstract

The invention belongs to the technical field of grinding wheels, and particularly relates to a rail transit cutting grinding wheel. The rail transit cutting grinding wheel comprises a basic grinding material composed of phenolic resin powder, corundum grinding materials and silicon carbide grinding materials; a hard alloy grinding material and a graphene grinding material are further arranged in the basic grinding material; a bonding agent is added into the basic grinding material, the hard alloy grinding material and the graphene grinding material, then grinding wheel modules are manufactured, the multiple grinding wheel modules are distributed in an annular array and then fixed to a grinding disc through connecting pieces, and circulating cooling mechanisms used for absorbing heat generated by cutting of the grinding wheel modules are further arranged on the two sides of the outer portions of the grinding wheel modules. According to the rail transit cutting grinding wheel, the toughness, hardness and heat resistance and thermal conductivity of the grinding wheel during cutting can be improved, the hard alloy grinding material is wrapped by the graphene grinding material firstly, and at the moment, heat generated during cutting of the hard alloy grinding material can be rapidly guided out through the graphene grinding material, and meanwhile, the hard alloy grinding material is effectively protected by the graphene grinding material.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a cutting grinding wheel for rail transportation. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain strength that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) by a bond. It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. According to different classifications of bonds, the common ones are ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. [0003] When the existing grinding wheel is cutting the track and rail, due to the hard characteristics of the rail, using a common grinding wheel for cutting has the following disadvantages: [0004] 1. Due to the hard nature of the rail, it is difficult to be cut by ordinary grinding whee...
