Pipe bellmouth polishing device for nodular cast iron pipe

Abstract

The invention relates to the technical field of nodular cast iron pipes, in particular to a pipe bellmouth polishing device for a nodular cast iron pipe. The pipe bellmouth polishing device for the nodular cast iron pipe comprises the nodular cast iron pipe and is characterized in that supporting bases are symmetrically arranged on the left side and the right side of the bottom of the nodular castiron pipe, anti-vibration pads are arranged at the bottoms of the supporting bases, the left side and the right side of the bottom of each anti-vibration pad are symmetrically provided with movable supporting rods, the left side and the right side of each connection rod are symmetrically provided with supporting feet, the outer wall of the center of a movable rod on the left side is in sleeved connection with a movable support, a thread bushing is movably connected to the bottom of the movable support, a worm is in inserted connection with an inner cavity of the thread bushing, the outer walls of the left side and the right side of the worm are sleeved with supporting blocks correspondingly, the left side of the worm is provided with a driving motor, the bottoms of the supporting feet areprovided with a supporting plate, the right side of the top of the supporting plate is provided with a lifting mechanism, the right side of the top of the lifting mechanism is provided with a dull polishing motor, and the power output end of the dull polishing motor is connected with a dull polishing wheel. The problems that the angle cannot be adjusted when the nodular cast iron pipe is polished, the labor intensity is large, and stability of a lifting platform is not high are solved.

Description

technical field [0001] The invention relates to the technical field of ductile iron pipes, in particular to a pipe socket grinding device for ductile iron pipes. Background technique [0002] The essence of cast iron steel pipe is ductile iron pipe, because ductile iron pipe has the essence of iron and the performance of steel, so it is called this. Graphite in ductile iron pipes exists in spherical form, and the size of general graphite is 6-7 grades. In terms of quality, it is required that the spheroidization level of the cast iron pipe is controlled to be 1-3, and the spheroidization rate is ≥ 80%. Therefore, the mechanical properties of the material itself have been better improved, and it has the essence of iron and the performance of steel. After annealing, the metallographic structure of the ductile iron pipe is ferrite plus a small amount of pearlite, and the mechanical properties are good, so it is also called cast iron pipe. [0003] Grinding is a kind of surfac...
