Single control circuit mechanism for punch press

Abstract

The invention discloses a single control circuit mechanism for a punch press. The single control circuit mechanism is characterized in that a diode is connected in parallel with an alternating current contactor in a circuit and then is connected in series with a normally open interlocking button and a normally closed interlocking button; a capacitor is connected between points A and B; points C and D are connected to a power supply; when both the normally open button and the normally closed button fail to run, the power supply supplies power to the capacitor through the points C and D; and when the normally open button and the normally closed button run at the same time, the circuit for the points C and D to support power to the capacitor is cut off, and the capacitor supplies power to the alternating current contactor, that is, outputting a signal.

Description

technical field [0001] The invention relates to a control circuit mechanism, in particular to a single control circuit mechanism for a punching machine, which belongs to the technical field of forging equipment. Background technique [0002] In the action function of the punching machine, the accuracy of a single action is very important in the entire production, not only will it affect the quality of the product, but more importantly: if the single action is inaccurate, it may even cause damage to the equipment and personal casualties; at present, in the control of a single action of the punch press, two methods of mechanical and electrical interlocking are mainly used, of which the mechanical type is mainly used for punches with small and medium tonnage pressures, while the electrical control type is mainly used for relatively small tonnage presses. Large tonnage pressure or relatively high-end punch presses; currently, the general system of punch presses that use electric...
