Nowadays, the core-mold vibration pipe-making technology has been accepted and recognized by more and more enterprises, becoming a good choice for producing large-diameter drainage pipes. The advantages of this technology are low production cost, high efficiency, environmental protection, and low labor intensity. It is also very suitable for the current situation of difficulty in employing workers and is suitable for older workers.
Today, the core mold vibration pipe making process has been accepted and recognized by more and more enterprises, becoming a good choice for making large-diameter drainage pipes. The advantages of this process are low production cost, high efficiency, environmental protection, and low labor intensity. It is also very suitable for the current situation of difficulty in employing workers and is suitable for older workers.
There are four forming processes for this technology: centrifugal, hanging roller, vertical vibration, and core mold vibration. Each process has different characteristics and unique advantages.
The later maintenance work of the core mold vibration pipe making process is also very important, especially the early maintenance work after pipe forming. The dry-hard concrete used has the characteristics of low water content, poor fluidity, and poor density. The concrete is prone to honeycomb, holes, and annular cracks, which seriously affect the overall strength of the concrete.
The common maintenance method is to cover it with a steam oxygen hood, which can be changed appropriately according to different seasons. For example, in summer, it can be naturally cured or steam cured, and in winter, it can be steam cured. It is particularly noteworthy here that the curing time of the positioning ring. Now many manufacturers, in order to speed up the rotation speed of the positioning ring, quickly remove it, which will not play a positioning role, and the pipe deformation is very large.
For dry-hard concrete, it can also be said to be a demolded bare product, so the maintenance work is particularly important, and corresponding control technologies should be adopted according to the season and weather conditions. In summer, water can be applied in time, and in winter, it can be stored to ensure the temperature and humidity of the product.
Below is an introduction to the operation process of the core mold vibration process.
The first step in core mold vibration is to assemble the mold, place the processed base in the assembly position, and place the frame on the base. Then, use a crane to lift the outer mold, insert it from above, close the mold, and complete the assembly. Use a crane to lift the assembled mold and place it on the outer workstation of the radial extrusion pipe making machine. This crane is specially modified according to the requirements of the overhead crane radial extrusion pipe making process.
Before starting pipe making, turn over the floor and turn the assembled outer mold to the inner pipe making workstation. The operator sets the necessary parameters according to the product specifications of the pipe, and then starts the braking pipe making program. The pipe material extruder automatically runs and performs the production process.
First, the extrusion head quickly descends, the mouth forming part rises, and the feeder starts feeding. The key to the core mold vibration pipe making process is control, and the working torque of the extrusion head prevents the steel frame from twisting. In the manufacturing of the upper part of the pipe, in order to better form the socket, a proper amount of water is usually added to the concrete at the end. After the pipe is extruded, turn the floor and transfer the extruded pipe to the outside workstation.
Then, use a crane to lift the mold with the finished pipe, transport it to the repair site, and then place the mold on the ground. The operator opens the mold, and the crane lifts the outer mold to complete the demolding of the extruded pipe material, thus basically completing the entire pipe making operation.
