Method of operating hydraulically driven stamping machine for punching e.g. fabric, involves using power consumption of electrically driven motor as control variable, while controlling electrically driven motor

摘要

#CMT# #/CMT# The method involves operating the stamping machine by controlling an electrically driven motor (102) that is rigidly coupled to a hydraulic pump (103). The hydraulic pressure value or the speed of movement of the stamping machine is used as a reference variable for controlling the stamping machine. The power consumption of the motor is used as the control variable. #CMT#USE : #/CMT# Method of operating hydraulically driven stamping machine for stamping materials such as fabric, leather, plastic and wood in different shapes. #CMT#ADVANTAGE : #/CMT# The precision of operation of the stamping machine is improved. The noise and power consumption of the electrically driven motor are reduced. The position of the stamping machine can be determined easily, and the duration of the stamping process can be defined favorably. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the motor and the control valve. 101 : Control valve 102 : Electrically driven motor 103 : Hydraulic pump 104 : Cylinder 105 : Chamber.
