Mold for producing concrete pipes

Abstract

The invention discloses a mold for the production of concrete pipes. The mold may include a cylindrical mold main body, the cylindrical mold main body is made of a steel plate rolled into a circle and has two ends open; the outer side of the cylindrical mold main body is provided with a plurality of Annular reinforcing ribs and multiple transverse reinforcing ribs and / or multiple longitudinal reinforcing ribs; the main body of the cylindrical mold is provided with a hoisting turning shaft. The mold for concrete pipe production provided by the application has the advantages of less investment, high efficiency, energy saving and environmental protection, and low maintenance cost in the later period. The mold continues to use the mature suspension roller process, and also combines the advantages of mandrel vibration and radial extrusion for vertical maintenance and quick demoulding, ensuring that customers have less investment, do not violate environmental protection, low maintenance and maintenance costs, and produce high-quality products. The product is of good quality. So that customers in need can achieve high-efficiency production mode on the basis of small investment in suspension roller technology. It is worth promoting and using on a large scale.

Description

technical field [0001] The invention relates to the technical field of concrete pipe production equipment, in particular to a mold for concrete pipe production which is suitable for the suspension roller production process and can realize rapid demoulding. Background technique [0002] Concrete pipes are also called concrete pressure pipes and reinforced concrete pipes. They can be used as sewer pipes in the foundation of urban construction, sewage, flood control and drainage, as well as water pipes and farm wells used in some special factories and mines. The preparation of the concrete pipe in the prior art is divided into three kinds of techniques: suspension roller technique, mandrel vibration technique and radial extrusion technique. The suspension roller process is a relatively traditional and stable process. The concrete pipe mold is produced by the suspension roller machine. After the production is completed, the concrete pipe that has not been solidified in the mold ...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the hanging roller process has low investment, mature technology, stable operation, and low maintenance costs, but the production efficiency is not high. If you want to improve efficiency, you need to heat and steam, which increases the cost and is not conducive to environmental protection.

Mandrel vibration and radial extrusion process are highly efficient, but the investment is too high and the technology is not yet fully mature
