Socket grinding device for nodular cast iron tube

Abstract

The invention discloses a socket grinding device for a nodular cast iron tube. The socket grinding device for the nodular cast iron tube comprises a grinding trolley, a base frame, a rail, a grinding mechanism and a drive oil cylinder used for driving the grinding trolley. The rail is horizontally arranged at the top end of the base frame. The grinding trolley comprises a base plate and two lines of walking wheels arranged at the bottom of the base plate. The two lines of walking wheels are matched with the rail in a rolling mode. The drive oil cylinder is horizontally hinged to the top end of the base frame. The end of a piston rod of the drive oil cylinder is hinged to one end of the grinding trolley. The grinding mechanism is hinged to the top surface of the grinding trolley. The socket grinding device for the nodular cast iron tube has the advantages that axial locating of a grinding wheel group is achieved through the drive oil cylinder, radial locating of the grinding wheel group is achieved through a lifting oil cylinder, and during production, it is only required that an operator operates the drive oil cylinder and the lifting oil cylinder; in this way, the automation degree is greatly improved, it is avoided that dust pollution does harm to the physical health of the operator, the production efficiency is improved, and labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of production auxiliary devices for ductile iron pipes, in particular to a grinding device for sockets of ductile iron pipes. Background technique [0002] At present, domestic and foreign ductile iron pipes need to process the inner and outer surfaces and end surfaces after casting. The existing ductile iron pipe inner and outer surfaces need to be sprayed. At the same time, in order to facilitate connection and sealing, the socket and socket end surfaces need At present, most factories basically use automatic equipment for the grinding of the outer surface, inner surface, socket end face and socket end face, but for the small groove at the socket end for installing the sealing strip and the groove of the socket concave surface In the grinding process, manual hand-held angle grinders and straight grinders are still used for grinding. The purpose of grinding is to clean the sticky iron and floating sand on t...

[0002] At present, domestic and foreign ductile iron pipes need to process the inner and outer surfaces and end surfaces after casting. The existing ductile iron pipe inner and outer surfaces need to be sprayed. At the same time, in order to facilitate connection and sealing, the socket and socket end surfaces need At present, most factories basically use automatic equipment for the grinding of the outer surface, inner surface, socket end face and socket end face, but for the small groove at the socket end for installing the sealing strip and the groove of the socket concave surface In the grinding process, manual hand-held angle grinders and straight grinders are still used for grinding. The purpose of grinding is to clean the sticky iron and floating sand on the fifth surface of the socket and in the small groove. Guaranteed to reduce leakage during future use. The current operation method requires operators to operate at close range. On the one hand, the labor intensity is particularly high, consumes physical strength, and the work efficiency is very low, which affects the production rhythm and is difficult to guarantee product quality. On the other hand, the dust generated during the grinding process directly affects the health of the operators, and also causes certain pollution to the working environment.
