Grinding cloth wheel and manufacturing method of grinding cloth wheel

Abstract

The invention relates to a grinding cloth wheel and a manufacturing method of the grinding cloth wheel. The manufacturing method of the grinding cloth wheel comprises a net cover warming step, a net cover glue coating step, a grinding cloth piece ranging step, a mold placing step and a warming and pressurizing forming step. The grinding cloth wheel manufactured by adopting the manufacturing method has the advantages that the grinding edges of each grinding cloth piece are respectively positioned on the same plane, so when the grinding cloth wheel is arranged on the grinding wheel machine to be used, operators only need to make a rotating shaft of the grinding cloth wheel to be vertical to the surface of a ground object, the grinding edges of all grinding cloth pieces can simultaneously realize the grinding on each position of the surface of the ground object at the uniform force, the smoothness of the surface of the ground object is ensured, the operation is simple and convenient, in addition, the grinding area in the unit time is large, and the grinding efficiency is high.

Description

technical field [0001] The invention relates to an emery cloth wheel for grinding metal surfaces and a manufacturing method of the emery cloth wheel. Background technique [0002] The emery cloth wheel is installed on a grinder, and the rotating shaft of the grinder is used to drive the emery cloth wheel to rotate at a high speed, so that the emery cloth wheel can grind or polish the surface of a metal object to be ground, and the surface of the object to be ground Grinding the rough surface, or removing the raised welding points on the surface of the object to be ground, so that the surface of the object to be ground of the metal material is bright, smooth and fine. [0003] see Figure 10 As shown, the abrasive cloth wheel 60 in the prior art mainly includes a mesh cover 61 and a plurality of abrasive cloth pieces 621 . Cooperate see Figure 11 As shown, the net cover 61 is in the shape of a disc, which has a shaft hole 611 and a fitting portion 612, the shaft hole 611 i...

Problems solved by technology

[0005] Therefore, when the above-mentioned emery cloth wheel 60 of the prior art is installed on a grinder for use, if the operator grinds at an angle that the rotational axis of the emery cloth wheel 60 is perpendicular to the surface of the object 72 to be ground, only the inner side of the emery cloth layer 62 has a larger thickness. part will contact the surface of the object 72 to be ground, and the part with a smaller thickness on the outside of the emery cloth layer 62 will not be able to touch the surface of the object 72 to be ground

like Figure 11 As shown, generally speaking, the operator must tilt the grinder so that the grinder can grind the surface of the grinded object 72 at the angle that part of the surface of the emery cloth layer 62 is attached to the surface of the grinded object 72. , but it is often difficult for the operator to grasp the inclination angle of the grinder, which instead causes the emery cloth layer 62 of the emery cloth wheel 60 to exert uneven force on the object 72 to be ground, resulting in the problem that the surface of the object 72 to be ground is uneven. Quite inconvenient, and because only part of the surface of the abrasive cloth layer 62 can be attached to the surface of the object to be ground 72, the area that can be ground per unit time is small, making the efficiency of grinding not good
