What are the advantages of core mold vibration technology?
Core mold vibration technology boasts high production efficiency, ensuring the supply of pipes for large-scale and emergency projects while maintaining consistent product quality. So, what are the advantages of core mold vibration technology?
What are the advantages of core mold vibration technology?
(1) Ground-based control and underground enclosed vertical molding. Compared to centrifugal and hanging roller processes, which are horizontal ground-based, this improves the working environment, reduces worker labor intensity, and promotes safe and civilized production;
(2) Dry production method is used. The workability of general concrete is between 20-60. High-frequency vibration of the core mold ensures high concrete density and product quality;
(3) After molding, the inner and outer molds can be removed immediately. Only one set of molds is needed for each diameter, ensuring consistent inner and outer diameter inch accuracy for each pipe, significantly reducing mold investment costs;
(4) Generally, steam curing is not required. The hydration heat of cement is used for moisture retention and insulation, and the process can be completed within 20 hours, saving a significant amount of energy;
(5) The frequency, amplitude, and excitation force of the vibration can be easily adjusted according to the production of different pipe diameters. The equipment is highly adaptable.
(6) It can meet the needs of diversified product specifications, producing extra-large diameter pipes and various shaped pipes, such as inspection wells, box culverts, pipes with bases, and anti-corrosion lined pipes;
(7) High production efficiency ensures the supply of pipe materials for large-scale and emergency projects. Under the condition of ensuring the number of shifts, a general workstation can produce more than 100 meters of medium and large diameter drainage pipes per day;
How to analyze the development trend of core mold vibration technology?
1. The application of core mold vibration technology is still in its infancy. Due to its significant technological advantages, the entire set of equipment has been put into production. The cost savings have brought huge economic benefits to enterprises, and it is expected to continue to develop rapidly in the next few years.
2. Automatic core mold vibration pipe-making equipment for producing small and medium-diameter pipes will be very popular. In addition to the main machine, supporting equipment should be further developed and improved, such as concrete mixing systems, special lifting and transportation equipment, high-performance double-layer steel skeleton welding machines, various shaped molds, etc. Continuously explore the adaptability of raw materials and production processes, and conduct research, trial production, and production of various specifications and varieties of products such as extra-large diameter pipes, inspection wells, box culverts, and special shaped pipes.
What are the causes of cracks in drainage pipes produced by core mold vibration and radial extrusion methods?
This is largely related to the technical principles of pipe making, but also to improper operation. First, the main causes of cracks in core mold vibration pipe making are: uneven ground in the demolding area, excessive rolling pressure during spigot and socket molding, and inaccurate steel skeleton dimensions. Second, the main causes of cracks in radial extrusion pipe production are excessive extrusion pressure set by the extrusion head and small circumferential cracks caused by intermittent laying. Among them, excessive extrusion pressure set by the extrusion head is the main technical reason for cracks in radial extrusion pipes. Intermittent laying easily produces small circumferential cracks. Due to the limitations of the extrusion process, distributed delamination cannot occur during drainage pipe production. Therefore, radial extrusion pipe making requires a certain degree of automation.
