Technical Advantages

1. High-quality frame design of German version

The mainframe frame adopts the high-strength welded frame structure designed by Zenit's patented technology, which is welded by the customized special section steel, with reasonable design, even and beautiful welding, and the whole frame undergoes the aging vibration treatment to ensure the high quality and high stability of the frame. The advanced structural design process makes the mainframe expandable, and the side mold opening and closing function, core extraction (board) function, polystyrene board implantation function, etc. can be added subsequently.

2.Automatic quick mold change system

When the mold is transferred to the host position, its lifting system realizes automatic mold change on the quick mold change device. The upper and lower molds are automatically clamped pneumatically, which is safe, efficient, simple to operate and convenient to maintain. It mainly includes:

Pneumatic mold clamping device: It mainly consists of mold bracket and pneumatic clamping rods on both sides, which assist in clamping and fixing the molds and damping when the host machine carries out pre-vibration and main vibration, so as to achieve the best vibration effect and prolong the service life of the molds.

Pneumatic indenter locking device: the indenter is fixed by the clamping device with airbag, which can easily and quickly replace the indenter, shorten the time of mold replacement and installation, and ensure the accurate docking of the lower mold frame and upper indenter.

Electric Mold Insertion Device: The mold mounting device is used to install the molds into the main machine and to feed and remove the molds from the machine by means of the electric mold bracket, which can be applied to most of the molds in the market, and special mold brackets can be used for special molds.

Mold Changing Device: Installed on the frame of the main machine, it is used for lifting and loading the molds when changing the molds, equipped with electric chain hoist and electric walking device.

4. “Ultra-dynamic” servo vibration system:

“Ultra-dynamic” servo vibration technology is a kind of high-efficiency, self-adaptive vibration system specially designed for brick machines; the servo motor can make the fastest response in the shortest reaction time, realizing the highest vibration performance, reducing the amount of cement used and shortening the production cycle, producing high-compact concrete products; the vibration system can flexibly adapt to the needs of different concrete products. The servo motor can make the fastest response in the shortest reaction time to realize the highest vibration performance, which can reduce the amount of cement, shorten the production cycle, and produce highly compact concrete products; the vibration system can be flexibly adapted to the production needs of different concrete products.

8 vibration units with mechanical balance set individually by 8 servo drives;

8 servo motors, individually mounted on the external vibration isolation beams of the motor supports;

5. Accurate servo control system

Through the signal feedback, control the phase and speed of vibration, synchronized motion control, high-speed standby, can be completed in a short period of time vibration and vibration elimination, to help shorten the molding cycle, and better braking effect. Through position and speed double closed-loop, control the excitation force only acts in the vertical direction, maximize the effective excitation force, and at the same time avoid the horizontal excitation force damage to the machine, prolong the service life of the equipment, and be able to make different settings for different product requirements, and produce high-quality products.

The press head, mold frame, aggregate car and fabric car are controlled by proportional directional valve with spool feedback, which has fast response time; the closed-loop control mode of displacement sensor/encoder-PLC-proportional directional valve-cylinder is adopted, which makes the control more accurate, and the action of the cylinder faster and more stable; the hydraulic station adopts variable piston pump, which doesn't output the pressure oil and unloads the pump when the hydraulic system reaches the set pressure to reduce the energy consumption; the hydraulic station adopts accumulator auxiliary oil supply, which reduces energy consumption; and the hydraulic station adopts accumulator auxiliary oil supply, which reduces energy consumption and reduces energy consumption. The hydraulic station adopts accumulator auxiliary oil supply, which can be used for multiple actions at the same time, and the pressure of the hydraulic system is stable; the hydraulic system has pressure sensors, which can be displayed on the operation panel for easy viewing; the hydraulic system has temperature sensors, coolers and heaters, which can effectively control the oil temperature, so that the hydraulic oil has a good performance.
