In a large steel forging production enterprise, an old friction press works day after day. This press has accompanied the enterprise through countless spring and autumn, and has made great contributions to the development of the enterprise. However, with the rapid development of science and technology, this traditional friction press gradually seems powerless, and its low efficiency, high energy consumption and high maintenance costs are becoming increasingly prominent.

The company's engineers know that in order to be invincible in the competitive market, it is necessary to transform and upgrade this obsolete friction press. So, they found Zhengzhou Hualong, a manufacturer specializing in the production of electric screw presses, to upgrade their friction presses.

The first stop on the transformation journey is the mechanical part. After removing the two-disc friction drive system, support arm, brake mechanism, motor and other components of the original machine, Hualong mechanical engineers retained the core components such as beam, base, column, pull rod, slider, screw, nut and ejector device. The spline sleeve is installed in the position of the screw flat wheel, and the servo motor is driven by the inner spline sleeve and the flywheel with the wheel groove, so that the rotating movement of the screw is transformed into the up and down reciprocating movement of the slider. This design not only simplifies the mechanical structure, improves the transmission efficiency, but also lays the foundation for the subsequent electrical transformation.

In the lubrication part, Zhengzhou Hualong engineers retained the original lubrication device, and improved the lubrication of the spline sleeve and bearings. They added a pneumatic refueling machine, through the PLC control of oil supply time and oil supply, to achieve automatic lubrication. This improvement not only reduces the mechanical failure caused by manual refueling in time, but also greatly improves the production efficiency.

The transformation of the electrical part is also remarkable. The engineers of Zhengzhou Hualong will remove the original motor, electrical cabinet and operator and replace it with a servo motor drive system. This system has the advantages of strong overload capacity, excellent anti-biased load performance, wide speed regulation range, good acceleration and deceleration performance, frequent start braking and strong positive and negative switching ability. At the same time, the installation of centralized button stations and safety grating greatly improves the safety of operation.

The friction press has a new look after the renovation. The servo motor direct drive technology makes the energy release more accurate, the product consistency is higher, and the pass rate is greatly improved. The touch screen simply sets the percussion process, which can completely simulate manual operation, and the continuous percussion speed is very fast, and the production efficiency is greatly improved. In addition, the characteristics of high efficiency and energy saving make the power saving rate reach about 55%, the starting current is small, and there is no impact on the grid. After the transformation, because the screw does not produce transverse radial force, the service life of the transmission screw, nut and die has been greatly improved, and the maintenance cost is reduced by about 35%. The most important thing is that the addition of multiple mechanical and electrical safety protection measures effectively avoids the occurrence of safety accidents.

This transformation journey not only revitalizes the friction press, but also brings significant economic benefits and market competitive advantages to the enterprise. Digital precision control allows enterprises to achieve a gorgeous turn from traditional manufacturing to intelligent manufacturing.
