Problems solved by technology

The existing grinding wheel cannot meet the requirement of single-sided force, and it is easy to cause the whole grinding wheel to fall off the circle. If it is light, it will damage the workpiece, and if it is serious, the grinding wheel will fly out when it rotates at a high speed, and it will hurt the operator.

Abstract

The invention discloses a cold sawing grinding wheel with a single hypotenuse structure and a preparation method thereof, comprising a steel substrate and an annular grinding layer; on the steel substrate, the contact surface between the steel substrate and the annular grinding layer is a horizontal Z-shaped Structure; in the horizontal Z-shaped structure, the upper vertical surface is higher than the lower vertical surface; in this way, the whole grinding wheel is observed from the appearance, the grinding layer is thick on one side and thin on the other side, with the grinding wheel installation hole as the inside, the outer thickness is thicker and the inner thickness is thinner The structure makes the grinding surface thick; the grinding layer is made of resin bond and abrasive. In order to increase the holding force between the bonding agent and the substrate, the present invention adopts knurling of the outer circle, grooves on the inner side of the outer circle, and copper plating at the connection between the abrasive layer and the substrate, so as to prevent the grinding wheel from being easily detached under force. In addition, this structure can maximize the use of the grinding wheel and save costs. And its shape can be adjusted according to the shape of the processing object, which is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of superhard abrasive grinding wheels, in particular to a cold saw grinding wheel with a single-bevel structure and a preparation method thereof. Background technique [0002] The cold saw is a new type of saw blade. During the metal sawing process, the heat generated by the saw blade saw teeth is transferred to the sawdust through the saw teeth, and the sawed workpiece and the saw blade remain cool. [0003] The teeth of the cold saw and its base are an integral structure, and the grinding wheel of the cold saw is directly cut on the outer circle of the saw blade according to the requirements of the tooth shape. The grinding allowance of the cold saw grinding wheel is large, and the grinding resistance is also much larger than that of other grinding wheels. [0004] There is a big difference in the way the cold saw grinding wheel grinds and the existing conventional grinding. The existing grinding wheel cannot meet...
