High-speed rotating centrifugal casting molding drum roller stabilizing device

Abstract

The invention provides a high-speed rotating centrifugal casting molding drum roller stabilizing device. A centrifugal casting molding drum is arranged on a centrifugal machine frame. A roller positioning device is fixed to a roller support. A roller stabilizing device body comprises an adjusting screw, a fixing sleeve, an opening-closing shaft cap, a shaft sleeve, a supporting sleeve, a hydraulic bearing and a roller. The fixing sleeve and the supporting sleeve are arranged on the roller support. The shaft sleeve is arranged in the supporting sleeve. The adjusting screw penetrates through the fixing sleeve and is arranged on the fixing sleeve. The adjusting screw is fixed in the shaft sleeve through the opening-closing shaft cap. The roller is arranged in the shaft sleeve. The hydraulic bearing is arranged between the roller and the shaft sleeve. The high-speed rotating centrifugal casting molding drum roller stabilizing device is stable in structure and suitable for centrifugal casting molding drums of different specifications, and the production cost is reduced; and through cooperation of the roller and the hydraulic bearing, radial run-out of the molding drum is prevented, splashing of molten steel is prevented, the casting quality is improved, and the working efficiency is substantially improved.

Description

technical field [0001] The invention relates to the field of centrifugal casting cylinders, in particular to a high-speed rotating centrifugal casting cylinder roller stabilization device. Background technique [0002] Many centrifugal casting pipe manufacturers have very few protective devices for the molded cylinder during production. Even if a protective device is added, only a beam is added above the centrifuge, which is regarded as a protection to prevent the molded cylinder from flying out. In addition, when producing a centrifugal cast pipe with a particularly small inner diameter, the stability of the amount of molten steel poured cannot be guaranteed in operation, so that the requirement for the inner diameter of the pipe section cannot be guaranteed. Producing pipe sections with smaller inside diameters is more difficult overall, and one very important factor is the alignment of the pouring cup. But in the production process, there is such a problem: the distance ...

AI Technical Summary

Problems solved by technology

But in the production process, there is such a problem: the distance has been adjusted, but because of the axial movement of the mold cylinder, the distance between the nozzle of the pouring cup and the edge of the center hole of the baffle is changed, resulting in the inner diameter dimension of the small inner diameter pipe section. deviation

If the inner diameter of the tube is too large, it can only be scrapped; if the inner diameter is too small, it will increase the difficulty of processing and increase the production cost

Although the common roller stabilization structure can reduce the transmission, it is not effective enough to perfectly solve the problem of movement; therefore, it is necessary to provide a stable structure that can effectively minimize movement and adapt to multiple Stabilizers for all cylinder models
