[0002] The counterweight is used to balance the centrifugal force and torque generated by the crankshaft connecting rod journal and crank, so that the crankshaft runs smoothly and reduces the load on the main journal bearing. The engine crankshaft is equipped with a counterweight to balance the centrifugal force and torque generated by the connecting rod big end, connecting rod journal and crank, so that the engine runs smoothly and reduces the load on the main journal. The counterweight is mostly used in forklifts.

[0003] During the processing of forklift counterweights, the counterweights need to be cut to produce specified counterweight products. A cutting device is used when cutting the forklift counterweights. The sharpness of the cutting blades on the existing cutting devices will gradually decrease after long-term use, which will affect the working efficiency. However, the existing forklift counterweight processing and cutting devices cannot automatically remind the staff when the sharpness is reduced to the maximum.

[0004] Therefore, we make improvements on this and propose a forklift counterweight processing and cutting device. Utility Model Content
