Title: Overload protector for tools and presses - responds to multiple loading or faulty functioning of drawing process
Inventor: LAUCKNER GERHARD
IPC: B21D55/00
Filed: 1973-07-18
Abstract: This protector is used mainly for fitting into a press tool used for cutting and drawing and for trimming deep drawn containers. Contactless initiators under one arm of the double arm levers transmit contacting signals to an electronic system which in turn actuates the solenoid valves of the press clutch and brakes for stopping the press. The strip holder has a pressure sensing pin which is pressed down excessively if more than one sheet strip is inserted and this excessive travel is transmitted to the one arm of the actuating lever which in turn actuates the initiator. In addition to the above, pressure sensitive segments are excessively displaced in the case of excessive amount of strip material between the dies and this once again actuates the other lever for triggering the initiator.
