Description

Technical Field

[0001] The utility model relates to the technical field of manhole cover grinding, and more specifically, to a grinding device for producing ductile iron manhole covers. Background Art

[0002] Ductile iron manhole cover is a kind of ductile iron product, named after the main material of ductile iron. Ductile iron is obtained by spheroidizing and inoculating to obtain spheroidal graphite. This structure effectively improves the mechanical properties of cast iron, especially plasticity and toughness, making the strength of ductile iron higher than carbon steel.

[0003] When a general manhole cover grinding device is in use, the staff first places the manhole cover on the workbench of the device, and then the staff starts the moving mechanism to drive the grinding mechanism to descend, and then starts the grinding mechanism. When the grinding wheel of the grinding mechanism moves to the surface of the manhole cover, the grinding wheel will grind the surface of the manhole cover, and at the same time, the rotation of the manhole cover is driven by starting the rotating mechanism, so that the surface of the manhole cover is polished. However, due to the force in the right direction generated on the manhole cover during grinding, the manhole cover will be offset. When the offset occurs, the grinding will make it inaccurate, so it needs to be modified and optimized. Utility Model Content
