Problems solved by technology

", and in the actual extrusion process, due to the characteristics of the concrete itself, the concrete will have different densities due to the difference in compression strength after molding (that is, the compaction situation). Using the extrusion head as described in the above patent, The adjustment of the concrete compression ratio during the pipe making process cannot be realized, and the preparation of better performance concrete pipes cannot be realized

Abstract

The invention relates to a radial extruding machine. The radial extruding machine comprises a frame (1), a power box (2), an air supply device (3), a feeding device (4), an insertion port forming device (5), a mold (7), an extruding head (8), a rotary chassis (9), a vibration device (10) and an oil cylinder (12). The extruding head (8) is internally provided with a plurality of upper extruding head bodies and lower extruding head bodies, wherein the upper extruding head bodies rotate coaxially, and the lower extruding head bodies do not rotate coaxially; and thus, by adjusting the eccentricity, the compression rate of pipe making concrete can be changed, so that the better extruding effect is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete pipe making, in particular to a radial extrusion machine. Background technique [0002] Existing concrete pipes are usually prepared by using a radial extrusion machine, specifically by extruding concrete by rotating an extrusion head in a mold. [0003] Among the existing radial extrusion machines, such as the radial extrusion pipe making machine shown in Chinese patent CN201120363082.8, the frame of the pipe making machine is square, and after being vertically installed on the ground, due to the Constant vibration, in extreme cases, will cause the overall displacement and vertical deviation of the radial extrusion machine, affecting production. As shown in the Chinese patent CN 107599155 A, "A pipe-making machine extrusion head is characterized in that it includes a cylinder, an inner shaft, and an outer shaft. The outer shaft is a hollow structure and is concentrically placed outside the inne...
