Centrifugal forming tool

Abstract

The invention relates to a centrifugal forming instrument, comprising an internal mold (1), an external support frame (2) of the internal mold and a centrifugal driving part (3) arranged on the external support frame (2). The centrifugal forming instrument is characterized in that the external support frame (2) is provided with at least a restraint hoop (4) which can restrain the shape of the internal mold (1) when centrifugation is carried out; the internal mold (1) enters or detaches from a tip of the external support frame (2); the restraint hoop (4) is detachable; the internal mold (1) consists of one or two or three or four or a plurality of modules; the restraint hoop (4) arranged in the middle part of the external support frame (2) is tensely connected with a connecting support bar piece which is longitudinally arranged. Therefore, a material padding device needs not to be moved away from one end of the forming instrument, the centrifugal driving part needs not to be moved away, and the internal mold can be directly assembled and disassembled from the tip of the external support frame; the occupied working surface is greatly reduced and all the terms of works are not mutually interfered. The centrifugal forming instrument is also characterized by simple operation, reliable operation, high production efficiency, good quality, etc., and is suitable for the production of thin-walled tubes made of various gelled materials.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of March 11, 2006, the application number of 200610067274.8, and the title of "a centrifugal forming tool". (1) Technical field [0002] The invention relates to a centrifugal forming tool. (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 roller, a pressure plate, a clamping bolt, a pr...

AI Technical Summary

Problems solved by technology

[0006] However, the structure of this kind of thin-walled cement pipe automatic forming centrifugal device is still relatively complicated. When installing and disassembling the forming mold in the rotating cylinder, the injection device needs to be removed first, and then the forming mold is assembled and folded. It is easy to produce interference phenomenon and inconvenient to operate
