YL7110 Vertical External Pulling Machine Mechanical Part: The main and auxiliary card cutter bodies are hydraulic, ensuring safe and reliable operation; The host undergoes strict heat treatment, which releases the internal stress of structural components and improves the wear resistance of moving parts, ensuring the long-term stability and durability of the lathe performance (some peers lack this process); The main slide plate is made of ductile iron, which has good stability and wear resistance (gray cast iron is generally used in the industry); The auxiliary slide (including small tonnage main slide) adopts imported linear ball guide rails, with a compact and reasonable structure, flexible and reliable movement, and high precision; c. Hydraulic part: The main pump and main hydraulic valves are made of Bosch Rexroth products from Germany, which have reliable performance and long service life. Advanced proportional control technology is used to achieve various stepless speed regulation to ensure reliable speed and precision of cutting; The pipelines, joints, and seals are made of imported brands, with no oil leakage and a beautiful appearance. The entire system adopts advanced energy-saving variable control form, only equipped with a 0.2KW cooler, and the oil temperature will not be too high during long-term operation. The operating efficiency is high, and the cost of use is reasonable. Compared with similar products from other manufacturers, the annual electricity cost savings are 50000 to 100000 yuan (similar products from other manufacturers have high oil temperature, which is essentially a large energy consumption, and then use about 5-11KW oil coolers for cooling, further increasing the energy consumption). High performance balance valves are used, and the main and auxiliary sliding plates stay for a long time without sliding down. When the cutting speed is 2m/min, the performance is stable and the smoothness is very high d. All the stroke switches in the electrical part are made of imported Omron products, which are waterproof, oil resistant, reliable in performance, and have a long service life. The high-power motor adopts soft start, and the operation adopts touch screen. The PLC is a Mitsubishi product.
