Thin walled pipe centrifugal shaper

Abstract

A centrifugal shaper for thin walled tube comprises a bracket (1), a riding wheel (2), a drive device (3) and an outer cover die (4). The riding wheel (2) is fixed on the bracket (1). The outer cover die (4) is arranged on the riding wheel (2). The centrifugal shaper for thin walled tube is characterized in that the drive device (3) drives the riding wheel to whirl; the outer cover die (4) contacts the riding wheel (2) depending upon at least one rolling loop (5) arranged on the outer cover die (4); the riding wheel (2) drives the outer cover die (4) to rotate; a pipe die is arranged in the outer cover die (4); and a fixed or a flexible stop device (8) is arranged at at least one end of the outer cover die (4). The fixed or the flexible stop device (8) can prevent the pipe die from movinguniaxially or / and biaxially. The centrifugal shaper is suitable for manufacturing the thin walled tubes of various gelled material. In particular, the centrifugal shaper is suitable for manufacturingthe thin walled tube covered with cement mortar fiberglass mesh.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 14, 2005, an application number of 200510133729.7, and a title of "a thin-walled tube centrifugal forming machine". (1) Technical field [0002] The invention relates to a centrifugal forming machine for thin-walled tubes. (2) Background technology [0003] At present, the production of thin-walled cement pipes for domestic cast-in-place concrete hollow floors is usually manually operated, which has high labor intensity, low production efficiency, uneven wall thickness, poor product quality, and waste of production materials. In order to solve the current The technical problems existing in actual production, the patent No. ZL03211400.1, titled "a kind of centrifugal device for automatic forming of thin-walled cement pipes" solved the above problems well. This thin-walled cement pipe automatic forming centrifugal device includes a support base, a support...

AI Technical Summary

Problems solved by technology

[0006] However, the structure of this thin-walled cement pipe automatic forming centrifugal device is still relatively complicated. When installing and disassembling the forming mold in the rotating cylinder, it is necessary to remove the injection device first, and then install and fold the forming mold, which occupies a large working surface and is prone to interference. Phenomenon, inconvenient to operate
