Development history of electric Screw press


The manufacturer of electric Screw press said that the Screw press originated in Germany in the 15th century. A man named John Donderberg invented a movable type printing machine. Press the ink coated movable type plate onto the paper through a spiral device. This machine is used as a wooden bolt press for pressing grapes and olive oil, which can be said to be the origin of all pressure machinery. It adopts a method of applying static pressure that gradually takes time to compress.

The manufacturer of the electric Screw press found that the Screw press for hot forging by static pressure was also displayed in the European Museum, presumably used for steel doors, windows and hardware parts of cities and churches in the Middle Ages. Later, the Screw press for forging was developed, which could install a runner on the upper end of the outer bolt shaft and use flywheel to accumulate energy to drive. Initially, the rotating flywheel was manually operated. Later, due to low efficiency and high labor intensity, two friction discs were installed on the upper part of the machine, and the cowhide was successfully wrapped around the flywheel through a connecting rod, causing them to come into contact and operate to generate power. This is the friction Screw press, which uses the friction drive method. In the early days, the friction Screw press was controlled by the operator through the manual steering wheel to operate the connecting rod. The up and down movement of the slider and the pressure intensity completely depended on the operator's proficiency.

Later, the connecting rod method disappeared and was replaced by button switches and foot pedal operation controlled by oil or air cylinders and relays. Later, the method of directly sensing the sliding speed through an encoding device was used to control the pressurized energy.

In addition, people have also developed a variety of methods, such as Hydraulic motor drive, electric motor direct drive, switched reluctance motor drive, permanent magnet synchronous servo motor drive, etc. Among them, the numerical control electric Screw press driven by switched reluctance motor in China has achieved good results in replacing friction press and in the transformation of friction press.
