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 resistance electric motor provides power to the compressor, with simple structure, free speed regulating, frequent start and stop, reversible movement with low, medium and high speed working features.

Description

technical field [0001] The invention relates to a numerical control method for main transmission of a mechanical press and a numerical control mechanical press, which belong to the field of forging equipment in the mechanical industry. Background technique [0002] NSI-1500(D) CNC press from Aida Engineering Technology Co., Ltd. (AIDA), HIF150 composite punching machine from Komatsu Manufacturing Machinery Co., Ltd. (KOMATSU), and double toggle mechanical press from Ohio State University Engineering Research Center They are all driven by AC servo motors. Because the cost of high-power AC servo motors is too high, the mechanical press is extremely expensive, and the angular displacement and angular velocity of the motor cannot be controlled. At the same time, there are defects such as the motor control system is complex, fragile, and difficult to maintain. . The main problems that have always existed in mechanical presses are narrow process adaptation range, low operating ef...
