Concrete Pipe Making Machine

Core-rising high-frequency vibration pipe making machine: The core-rising high-frequency vibration pipe making machine technology introduced from Spain combines the advantages of radial extrusion and core mold vibration, making up for the shortcomings of the two processes:

1. Combining the advantages of radial extrusion process, fast material feeding and fast molding, the production efficiency is higher than the core mold vibration process. The production capacity of the core-rising high-frequency vibration pipe making machine is slightly lower than that of the radial extrusion process, and the average production efficiency of a single pipe is 2 to 3 minutes per pipe;

2. Combining the advantages of the core mold vibration process, high-frequency vibration fully liquefies the dry and hard concrete, and the density and strength are higher than the radial extrusion process; reaching the GB/T 11836-2009 Concrete and reinforced concrete drainage pipes” “GB/T16752-2017 Concrete and reinforced concrete drainage pipe test methods” requirements;

3. It can produce reinforced concrete pipes with an inner diameter of 300~1500*2-3 meters and various interface types: flat end, socket end, steel socket end, flexible tongue and groove, etc.;

4. The dry hard concrete is fully liquefied and compacted by high-frequency vibration molding, without moving the pipe body concrete, so that the pipe body’s anti-seepage level is further improved, no steam curing is required, and the strength can reach more than 80% after 3-4 days of natural curing; reduce the production cost of the enterprise.

Features of high-frequency core mold vibration pipe making machine:

① Low amplitude, high frequency (5000-6000rpm), strong excitation force, high density of components, basically no pores on the surface; no secondary plastering treatment is required, simple water roughening is sufficient.

② Short molding time due to large excitation force; 300-600 double tube molding time is 4-5 minutes, 800-1200 single tube molding time is 5-6 minutes.

③ It can produce cement pipes of various shapes such as flat pipes, tongue-and-groove pipes, socket-and-spigot pipes, lined PVC pipes, lined fiberglass pipes, double steel socket pipes, flexible A-type steel socket pipes, etc.

④ No steam maintenance, no waste slurry; environmental protection, and reduced production costs.

Since the high-frequency vibration pipe making machine uses dry hard concrete (Vebe consistency 20-40S) for high-frequency vibration molding, the concrete will liquefy and gradually become dense, and a hydrothermal reaction will occur. The internal temperature and strength of the concrete will gradually increase. After molding, only measures need to be taken to prevent moisture evaporation (wrap the outside of the pipe with plastic film or add a plastic cover); no steam curing is required, and the concrete components can reach 70% strength after natural curing for 3-5 days.

Technical features and advantages of DN800-3000 high-frequency core mold vibration pipe making machine:

The high-frequency vibration pipe making machine independently developed by our company has broken through the technical bottleneck of the original domestic core mold vibration, and increased the frequency of the vibrator from the original 4000rpm to 5000-6000rpm, which has taken the domestic core mold vibration equipment to a new level and made a significant contribution to the domestic pipe making industry!

High-frequency vibration has the characteristics of large excitation force, high frequency and small amplitude. It has superior performance than traditional core mold vibration equipment! The component products produced by the strong excitation force have no pores, high density, high strength and high efficiency, and the daily output is 1.5-2 times that of traditional core mold vibration equipment. It greatly improves production efficiency and reduces production costs for customers, and improves the market competitiveness of products!

1. The bearings used for the inner mold vibrator and the main bearing seat are all German-made Schaeffler (FAG) bearings, and are accompanied by import customs declaration documents. The maximum speed of the vibrator is 6000rpm, and the exciting force is adjustable in five levels, namely 398kN, 364kN, 280kN, 180kN, and 132kN.

2. The main engine inner mold vibrator, shock-absorbing cross, and main frame produced by our company are fixed once, that is, when the inner mold needs to be replaced, there is no need to disassemble the vibrator and the main frame again. You only need to loosen the tensioning device on the vibrator to remove the inner mold for replacement. This not only saves the time of changing the mold, but also avoids the oil leakage caused by the frequent disassembly of the oil pipe on the vibrator.

3. The steel plate used for the mold is Q345 high-strength steel plate, and the mold is light in weight and high in strength.

4. The bottom mold and the socket mold are cast steel parts (made of ZG270-500) and have been aging treated. They have high strength and small stress deformation, which effectively ensures the accuracy of the cement pipe mouth size.

High-frequency vibration table manhole machine is a new type of prefabricated concrete inspection well equipment developed and manufactured by our company. It is our company’s invention patent product (patent number: ZL 2016 1 1007746.0). The advantages of this equipment are high versatility. It can produce various cement components such as square wells, round wells, rectangular wells, septic tanks, cement pipes, etc. One machine has multiple uses, helping customers solve the problem of multiple investments.

Features of the new high-frequency vibration manhole equipment:

1. The high excitation force generated by the high-frequency vibrator is used to implement high-frequency vibration (5000-6000rpm) molding on dry hard concrete, achieving steam-free curing, immediate demoulding, energy saving and environmental protection;

2. The well body and the bottom of the well are formed at one time, and the bottom of the well faces upward during production, solving the problem of secondary molding in traditional processes;

3. Since this process uses a high-frequency vibration table (5000-6000rpm) to vibrate, the entire component is vibrated longitudinally, and the entire well body and the bottom of the well are vibrated evenly, the component has high density, and there are basically no pores on the surface;

4. After vibration molding, the mold is automatically flipped using the axial eccentric force, and the bottom of the well is demoulded downward, and the bottom of the well will not collapse, crack, and seepage, etc.; improve production efficiency;

5. The equipment is simple to operate and has high process versatility. It can produce various cement components such as circular inspection wells, rectangular inspection wells, U-shaped grooves, and cement pipes;

6. The high-frequency vibration table uses high-performance spring vibration reduction, with good upper amplitude transmission effect and good lower vibration reduction effect.
