Method for manufacturing grinding wheel of tobacco shredder

Abstract

The invention discloses a method for manufacturing a grinding wheel for shredding tobaccos. The method for manufacturing the grinding wheel for shredding the tobaccos comprises the following steps: grinding the excircle of the grinding wheel, inlaying nut faces and holes, inlaying nuts and turning a working end face and a bevel edge; the method for grinding the excircle comprises the following steps: removing quartz sand on the grinding wheel which is out of a kiln completely, clamping the working end of the grinding wheel by a chuck jaw and shaking a transverse feed handle and a longitudinalfeed handle; and starting a lathe and the grinding wheel, shaking the longitudinal feed handle and the transverse feed handle by hands for feeding and grinding the grinding wheel, controlling the amount of feed by longitudinal feed, then feeding in a transverse direction, grinding, stopping feeding when approaching to the chuck jaw, feeding in the transverse direction again, increasing the amountof longitudinal feed gradually, grinding and finally, feeding in the transverse direction automatically to finish the grinding of the excircle of the grinding wheel. The invention can effectively reduce the baking deformation of a finished product, reduces the processing procedure and is also convenient to dry, bake and transport comparatively; the generated finished product has bulking property,good fluidity and high forming strength of a green pressing; and the finished product has high accuracy of geometric dimension, convenient installation, uniform tissue and excellent safety and grinding performance.

Description

technical field [0001] The invention relates to a method for manufacturing a grinding wheel, in particular to a method for manufacturing a grinding wheel for a tobacco cutting machine. Background technique [0002] After the grinding wheel has been roasted and solidified, its size, shape and mutual position accuracy of each surface cannot meet the technical requirements for use, and must be turned, ground and ground. The units that use the grinding wheel also have to turn due to the urgent need for production and the discrepancy between the specifications of the grinding wheel and the requirements for use. Due to objective technical reasons, traditional knife bowls are mostly used for turning at home and abroad. In the process of processing with it, the grinding wheel drives the quenched No. 45 steel thin-walled knife bowl to rotate at a high linear speed (300-400m / min), and performs cutting to remove the excess of the grinding wheel. Due to the high-speed rotation of the ...

AI Technical Summary

Problems solved by technology

Due to the high-speed rotation of the processed grinding wheel and the cutter bowl, there is a lot of dust and noise during processing, and the cutting depth and feed rate are small, so the processing efficiency is low, the overall cost is high, and the labor intensity of the operator is high.

Such as the use of large-grain diamond tools, the price is expensive, and because of the low bending strength of diamond, it is easy to be damaged during cutting, resulting in a small cutting depth and feed rate when using it to cut the grinding wheel, and it is generally only used in finishing machining.

[0003] The existing coated diamond grinding wheel does not have a firm chemical metallurgical bond on the bonding surface between the coated metal, the substrate and the abrasive, and the abrasive is actually mechanically embedded in the coated metal, so the holding force is small, and the diamond particles are under load. Heavy high-efficiency grinding is easy to fall off (or the coating flakes off), resulting in overall failure; in order to increase the holding force, the thickness of the coating must be increased. As a result, the exposed height of the abrasive grains and the chip space are reduced, and the grinding wheel is prone to blockage. The heat dissipation effect is poor, and the surface of the workpiece is prone to burns

At present, the domestic electroplating grinding wheel manufacturing has not realized the optimal design of the grinding wheel according to the processing conditions. These inherent disadvantages of the single-layer electroplating diamond grinding wheel will inevitably greatly limit its application in high-efficiency grinding.
