Problems solved by technology

[0005] However, the pipe-making methods of "mandrel vibration", "centrifugal" or "suspension roller" represented by the above-mentioned patent documents still have the following disadvantages:
[0007] 2. The "centrifugal", "suspension roller" and "mandrel vibration method" are used to produce concrete pipes. Because the mold or mandrel needs to rotate, it is difficult to control the process of conveying concrete raw materials during production, and it is difficult to use advanced equipment with high transmission efficiency. , so the use of manpower is large and the production efficiency is low
[0008] 3. Using "centrifugal", "suspension roller" including "mandrel vibration method" to produce reinforced concrete pipes, there are many transmission and rotating equipment, which will be damaged and worn during the production process, the failure rate is high, and the amount of maintenance is large, which directly affects Production efficiency and increased production costs
Insufficient thixotropic reaction of concrete
The plasticization and liquefaction degree of concrete is poor. Therefore, using the existing "mandrel vibration method" to produce the outer mold and inner mold structure of reinforced concrete pipes, the demoulding is inconvenient, and the produced concrete pipe wall is very rough. And it is inconvenient to demould, and it is easy to cause the defect of concrete pipe collapse and deformation

Abstract

The invention discloses an extrusion demoulding structure for producing reinforced concrete pipes. The extrusion demoulding structure for producing the reinforced concrete pipes comprises a vibrating table, an internal circle mould vibrating cylinder, an external circle mould cylinder structure and a hydraulic extrusion device, wherein the internal circle mould vibrating cylinder comprises an internal circle mould cylinder, an internal circle mould connecting bolt, an internal circle mould support ring and an internal circle mould high-frequency vibrator; the external circle mould cylinder structure comprises an external circle mould bottom ring, an external circle mould connecting bolt, an external circle mould cylinder and a mould baffle ring; the hydraulic extrusion device comprises a hydraulic extrusion ring, a hydraulic device, a hydraulic snap ring and an extrusion work shaft. The invention provides the brand new extrusion demoulding structure, the demoulding is more convenient, the walls of the produced concrete pipes are smoother, the extrusion demoulding structure is applied in a whole system for producing the reinforced concrete pipes, an electric motor does not need to drive the mould to rotate, and futile actions are avoided, so that not only can the power for producing the reinforced concrete pipes be greatly reduced to achieve the aim of energy conservation, but also more scientific and efficient conventional equipment can be adopted to match with the structure as the structure is not provided with transmission and rotation mechanisms.

Description

Technical field [0001] The invention relates to the technical field of concrete pipe manufacturing equipment, and specifically to an extrusion demoulding structure for producing reinforced concrete pipes. Background technique [0002] Concrete means concrete. Reinforced concrete pipe is commonly known as reinforced concrete pipe.
