Abstract

1300397 Safety device METAL BOX CO Ltd 16 Dec 1970 [23 Dec 1969] 62501/69 Heading F2J A riveting machine has a movable head 15 which approaches a workpiece 23 to within a distance X after which an actuator 18 drives a punch with full force. A safety device comprises a valve 26 to the valve member 31 of which the head 15 is attached which is actuated under the control of a pedal 20 and valve 19 to move the head 15 gently towards the workpiece until a spacing X is reached which is less than would allow the introduction of a finger. At this point an outlet port is opened which by a pilot input to a trip valve 27 allows the actuator 18 to operate with full force. If the head 15 is engaged before the distance X is reached the valve 30 remains closed and the actuator 18 cannot operate. In place of the piston actuator shown a motor may be used in which case a pneumatic clutch is controlled by the outlet port 30. The safety device may be used with stamping punching or similar machines.
