Pressure-controlled forming system with high production efficiency

Technical Field

The invention relates to the technical field of pressure control forming, in particular to a pressure control forming system with high production efficiency.

Background

The pressure tank is used for regulating and storing water quantity and keeping the water quantity at a required pressure by utilizing the compressibility of air in the tank, so that the pressure tank is also called as air pressure water supply equipment and is equivalent to a water tower and an elevated water tank. Since its water supply pressure is maintained by compressed air in the tank, the installation height of the tank can be unlimited. In addition, the equipment has the advantages of low investment, high construction speed, easy removal, high flexibility and high automation degree, and is very suitable for supplying water to medium and small villages with sufficient water sources and normal power supply. But the water regulating quantity is small, the pressure attenuation is fast, the starting of the pump is frequent, the operation cost is high, and the pump is not suitable for users with large water consumption and stable pressure requirements.

The original device depends on vacuum negative pressure of the middle section of the machine, the original common upper die device applies pressure to assist forming, and the original processing and forming technology is relatively backward. The defects of unstable pressurization, insufficient molding and the like are easy to occur, and the single lower die is cooled to cause long processing cycle period and low efficiency.
