Problems solved by technology

However, the existing technology produces bimetallic wear-resistant composite pipes figure 1 The axial positioning of the pipe is to use the centrifugal casting machine to install two positioning rings on the outer surface of the carbon steel outer tube. The positioning rings are fixed by locking bolts, and the positioning rings are respectively clamped on the two rotating rollers. Axial positioning is performed on the inner or outer side of the axial direction, which is time-consuming and labor-intensive for positioning

Abstract

The invention discloses an axial play positioning device of a bi-metal composite wear resisting pipe during centrifugal casting. The device comprises two parts of a front end positioning wheel and a back end thrust positioning wheel; the front end positioning wheel and the back end thrust positioning wheel are respectively mounted on the outer sides of pipe end blockage plates at two ends of a carbon steel outer pipe for axial positioning; rolling bearings are adopted as the front end positioning wheel and the back end thrust positioning wheel, so that the carbon steel outer pipe can axially adjust the length, and the carbon steel outer pipes with different diameters can be adapted to in the vertical direction; and because of elastic support of a spring, the back end thrust positioning wheel is always located in an axial play contact state in the casting period, the combined surfaces are stable in contact without generating axial movement and vibration, the positioning is reliable, and the defects in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of metal centrifugal casting machines, in particular to an axially moving positioning device for centrifugal casting of bimetal composite wear-resistant pipelines. Background technique [0002] Metallurgical mines usually use airflow to transport solid mineral powder. The conveying pipeline usually consists of straight pipes and bent pipes with different angles to change the direction of mineral powder flow. The existing conveying pipeline usually adopts a bimetallic wear-resistant composite pipe. It includes an outer tube and a wear-resistant inner tube that are compounded sequentially from the outside to the inside. The outer tube is a carbon steel outer tube, and the wear-resistant inner tube is a cast wear-resistant alloy steel wear-resistant inner tube. The bimetallic wear-resistant composite tube has a simple structure and low cost. , by setting the outer pipe and wear-resistant inner pipe that are com...
