Production device for ductile iron pipe fittings

Abstract

The invention discloses a production device for ductile iron pipe fittings, relates to the technical field of production of ductile iron pipe fittings, and solves the problems that the cost of grinding devices is increased, the time spent on installing the pipe fittings twice is long, and the grinding efficiency of the pipe fittings is reduced as the surface and the mouth of the ductile iron pipefittings are ground by two types of grinding devices respectively. A first sealing strip is fixedly connected to the mouth of a grinding box, and a first driving motor and a control panel are sequentially arranged on the other side of the grinding box from top to bottom. A supporting column is fixedly connected to the side of the lower end of the grinding box. A dust collector is fixedly connectedto the lower end of a collecting cover. Outer clamping mechanisms are arranged at both ends of a mounting rod, and an inner clamping mechanism is arranged in the middle of the mounting rod. A first grinding mechanism is arranged at the lower end of a first hydraulic cylinder, an electric slider is arranged at the upper end of an electric slide rail, and a second grinding mechanism is arranged atthe upper end of the electric slider.

Description

technical field [0001] The invention relates to the technical field of production of ductile iron pipe fittings, in particular to a production device for ductile iron pipe fittings. Background technique [0002] Nodular cast iron pipe fittings are made of magnesium or rare earth magnesium combined with gold nodulizers added to molten iron before pouring to spheroidize graphite and reduce stress concentration so that the pipe has high strength, high elongation, impact resistance, corrosion resistance, and good sealing. Advantages of pipe fittings; the inner wall is lined with cement mortar, which improves the water delivery environment of the pipeline, increases the water supply capacity, and reduces energy consumption; the nozzle adopts a flexible interface, and the pipe itself has a large elongation rate, which makes the pipeline more flexible. In the buried pipeline, it can work together with the soil around the pipeline to improve the stress state of the pipeline, thereby...
