Heavy-load grinding wheel for self-adaptive cooling based on normal grinding force of grinding area

Abstract

The invention discloses a heavy-load grinding wheel for self-adaptive cooling based on normal grinding force of a grinding area. The heavy-load grinding wheel comprises a grinding wheel substrate, a grinding block, a cooling spray bottle, a spray bottle nozzle, a plate-shaped heat pipe radiator and a self-resetting mechanism. During work, the grinding block entering the grinding area compresses the self-resetting mechanism under the normal grinding force and extrudes the cooling spray bottle at the same time, and then a cooling liquid is sprayed out of the spray bottle nozzle. Pressure springs in the self-resetting mechanism are adjusted to set a critical value of the normal grinding force critical value, when the normal grinding force is reduced to below the critical value or the grinding block is separated from a grinding working area, automatic resetting of the grinding block is achieved through the self-resetting device, and the cooling spray bottle stops spraying of the cooling liquid. Self-adaptive internal cooling of the heavy-load grinding wheel is achieved. The heavy-load grinding wheel is compact in structure, the spraying flow of the cooling liquid can be adjusted in real time according to the working condition, the cooling effect is greatly improved, the wear rate of the grinding wheel in heavy-load grinding is effectively reduced, and the service life of the heavy-load grinding wheel is prolonged.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a heavy-duty grinding wheel with self-adaptive cooling based on the normal grinding force in the grinding zone. [0002] technical background [0003] The development of heavy-duty grinding wheels depends on the development of the iron and steel industry. It is mainly used in the iron and steel industry for grinding steel ingots, billets, steel plates and surface cleaning of various castings. Its working characteristics are high grinding pressure and high grinding efficiency. Heavy-duty grinding wheels need to work under high load pressure to achieve high-speed and efficient grinding, so this requires high mechanical strength of the grinding wheel, and the mechanical strength of the grinding wheel depends on its structure. [0004] The invention patent with the publication number "CN104308757A" and the invention title "a superhard material metal bond skeleton type high-spe...
