Problems solved by technology

On July 14, 2004, the State Intellectual Property Office of the People's Republic of China authorized the utility model patent No. ZL03254142.2 named "Electric Screw Press". It uses an AC servo motor to drive the screw press through gear transmission. Because the motor The cost of the control system is high, the control circuit is complex, fragile, and difficult to promote
The main problem of the above-mentioned and existing screw presses is that the angular displacement and angular velocity of the screw, that is, the displacement and speed of the slider, cannot be numerically controlled.
At present, there is no screw press that can realize the numerical control of slider displacement and speed in industrial production.

Abstract

The screw extruder drive digital control comprises inputting running data by the operator and work station control computer control motor running, with the motor using switch magnetic resistance speed regulating motor, based on the input data, through the calculation of the work station control computer control motor, switch magnetic resistance speed regulating motor driving the extrusion of the screw. Switch magnetic speed regulating motor provides power to spiral compressor, through regulating angular displacement and velocity of the speed regulating motro to control the displacement and speed change of the slide of the compressor, realizing digital control fo the spiral compressor with simple structure, free from speed regulation, easy control of the slide displacement velocity.

Description

technical field [0001] The invention relates to a numerical control method for transmission of a screw press and a numerical control screw press, which belong to the field of material forming equipment. Background technique [0002] Because the electric screw press does not use low-efficiency friction transmission, it has the shortest transmission chain and high efficiency, so technicians from various countries continue to conduct research. German Lasco Company and Weingarten Company produced electric screw presses using variable frequency speed regulation motor technology, and Japanese Enomoto Company also developed a screw press driven by AC servo motors in 2001. On July 14, 2004, the State Intellectual Property Office of the People's Republic of China authorized the utility model patent No. ZL03254142.2 named "Electric Screw Press". It uses an AC servo motor to drive the screw press through gear transmission. Because the motor The cost of the control system is high, the ...
