Technical performance of 25t aluminum bar vertical casting machine.

1. Double proportional control (electric adjustment of pressure and flow, with multi-stage pressure and speed control and low-pressure mold clamping protection). 2. Double-loop design (the injection system and the pressurization system are designed independently and do not affect each other, zero failure). 3. Four-stage injection or multi-stage uniform acceleration system: a, maximum speed >; It can effectively control the filling time and the forming effect of die casting. B, the minimum speed is 0. 1-0.7m/s, which can be accurately controlled to avoid the problem of gas interception caused by air entry. C, the pressing time is less than or equal to15 m/s, and the pressing speed can be changed according to the process requirements, so that the density of the die casting can be enhanced without deforming the product. D, idling cycle time is shortened by more than 15%, oil pump flow is increased by more than 20%, cooling capacity of cooler is increased by more than 100%, and product yield is increased by 65438+. 4. International excellent PLC man-machine interface control system, data storage and monitoring function of die-casting products, timely alarm and inspection to prevent a large number of defective products. 5. Unique static and dynamic double core-pulling performance ensures that high-precision and difficult products can be formed at one time. 6. Higher rigidity (refer to the technical standards of HPM in Europe and America, which is firmer, more stable, safer and more convenient to maintain) 7. Automatic lubrication device for hammer. 8. Independent rapid mode locking system, impact resistance, long service life, fast production speed, and the shift output is increased by more than 15%. 9. The scientific installation technology of liquid nitrogen ensures the matching accuracy and prolongs the service life. 10. High-quality cast steel formwork, good rigidity and wear resistance, checked and designed by finite element analysis technology, reasonable stress distribution and high clamping accuracy. 1 1. Central electric lubrication system, which lubricates the machine regularly and quantitatively, so as to improve the service life. 12. adopt famous electrical appliances and hydraulic components from Europe, Japan and Taiwan Province province of China. 13. Hydraulic drive to adjust the die thickness structure. 14. Electric adjustment control of mold opening and closing stroke. 15. The injection system adopts European pull rod structure, and the center and eccentric injection position are selected, which is convenient to adjust and has high precision, and is suitable for various complex molds. 16.2000T large die casting machine adopts hydraulic pull rod device to replace large die safely and quickly. 17. Islanding design concept of die casting unit, with a variety of intelligent and advanced peripheral interfaces and software packages reserved.
