Core Mold Vibrating Concrete Pipe Machine

This concrete pipe making machine combines vibrating core and is used with a mold to prepack and vibrate concrete within the mold to produce concrete pipe.
The core molding vibrating concrete pipe production process is that the inner and outer molds are vertically erected on the bottom bracket (disk) in the pit, after which the concrete mixture is poured into the pipe mold, which is liquefied by the strong vibration force generated by the high frequency vibrator of the inner mold, filling the mold and exhausting the air, and concrete pipe is then compacted. The upper end of the pipe is equipped with a setting ring, which is lightly rolled and rubbed by the hydraulic pressure to compact the shape.

This concrete pipe making machine is used to produce concrete pipe types of socket type, flexible tongue and groove, flat shape and steel socket reinforced concrete drainage pipes, available in sizes DN1350-DN3000 and lengths of 1-2.5m.

Advantage
1. The inner core vibrates sufficiently and uniformly, and the concrete density is good;
2. The immediate demoulding process is adopted, and the production efficiency is high;
3. The amplitude of the inner core mold can be adjusted steplessly to meet various process parameters;
4. The pipe socket is formed with a steel cap to minimize the error of the pipe interface;
5. Reliable structure of the main machine and use of cooling methods to extend its life;
6. This mandrel vibration concrete pipe making machine is energy-saving and environmentally friendly, and the cost of pipe making is low;
7. This pipe making system uses frequency conversion speed regulation system and programmable controller to adapt to flexible production process parameters;
8. Underground closed vertical molding, ground control, production environment and working environment have been greatly improved;

1. Vibrating mandrel：a fixed eccentric block and a movable eccentric block are a group of vibrators，each mandrel is composed of 3 sets of vibrators. The exciting force can adjust the angle of the eccentric block arbitrarily according to the size of the product diameter, so that the exciting force can meet the compact forming requirements of different diameters;
2. Rotary concrete distribution machine: the conveyor belt adopts flat type conveyor belt, and the entire concrete distribution machine adopts the reducer drive, 360-degree rotary feeding realizing uniform distribution, reliable transmission after adjustment with long service life;
3. Frame: a cross-shaped frame body is welded by rectangular steel pipes, with good overall rigidity. The bearings of the transmission shaft are imported high performance bearings. The transmission of the transmission shaft and the vibration mandrel is a flexible connection transmission composed of a hollow shaft and a rubber sleeve, which allows high transmission efficiency, stable operation and long service life;
4. Gantry Frame: the oil motor is used for the walking of the gantry. The positioning of the gantry, the lift and the grinding are realized by means of oil cylinders. The structure is simple and the operation is convenient. The rotating shaft of the gantry is a long shaft with good rigidity to ensure reliable rotation. The frame is a gantry body with a box-shaped structure. Before the foundation, 10 M36 bolts are used to adjust the position of the gantry and the frame, which is convenient for installation and adjustment;
5. Motor: use 2 sets of 22 motors with variable frequency speed regulation for high power to ensure the speed synchronization of the 2 motors;
6. Hydraulic system: the variable vane pump is driven by a 7.5KW motor, and the inlet and return oil filters and air filters are used to ensure the cleanliness of the oil in the hydraulic system, making the operation smoother and the service life longer;
7. Circulating oil cooling and lubricating system: the lubricating part is equipped with an air cooler to prevent the bearing heating temperature from being increased due to the high oil temperature of the lubricating oil, which affects the production and service life;
8. Control system: high degree automation, international famous brands are selected for the configuration of purchased parts, so the working performance is safe and reliable.
