A perforated capillary automatic graphite spreading device

Abstract

The invention provides an automatic graphite scattering device of a perforated capillary pipe, and belongs to the technical field of machine manufacturing. The automatic graphite scattering device of the perforated capillary pipe can be used for scattering graphite to an inner cavity of the perforated capillary pipe in the process of manufacturing pipes in a steel tube plant, so as to reduce the frictional force of a pipe expander top and an ejector pin and the inner wall of the capillary pipe, reduce inner rolling scars and improve the interior surface quality of steel tubes. The automatic graphite scattering device of the perforated capillary pipe comprises a material storage tank, a distributing mechanism, a feeding mechanism, an electronic control system, a thermal inductive probe, a return roller table, a base and a protective cover; the material storage tank is provided with a stirrer and a vibrator; the lower part of the material storage tank is provided with a motor-driven packing auger, which is used for providing graphite to the feeding mechanism quantitatively; the feeding mechanism is installed on the base and driven by a cylinder, and the graphite is fed into a cavity of a steel tube and then returned to a waiting position; the electronic control system comprises a detection element, a control element, an operation box and the like, and is used for the manual debugging and automatic operation of the complete equipment. According to the automatic graphite scattering device of the perforated capillary pipe provided by the invention, the complete equipment is integrated as a whole, thus the structure is compact, the airtightness and corrosion resistance are good, and in combination with site conditions, the installation and maintenance are convenient.

Description

technical field [0001] The invention relates to an automatic graphite sprinkling device for perforated capillary tubes, which belongs to the technical field of mechanical manufacturing; it is used for sprinkling graphite into the inner cavity of perforated capillary tubes during pipe expansion production in steel pipe factories, so as to reduce the distance between the top and ejector rod of the tube expander and the inner wall of capillary tubes. friction, reduce internal rolling scars, and improve the quality of the inner surface of the steel pipe. Background technique [0002] When the steel pipe factory expands the production, in order to reduce the friction force between the head of the pipe expander and the mandrel (mandrel) and the inner wall of the capillary, reduce the inner rolling scar, improve the quality of the inner surface of the steel pipe and the uniformity of the longitudinal wall thickness of the continuous rolling pipe, and extend the expansion To extend ...
