A device for palpating and cool periodically the front surface of at least one punch of a press automatic a transverse transport

摘要

P on the frame 1 of a press is articulated a feeler 9 which is described a periodic sweeping movement in the oscillating about a horizontal axis a at the rate of the work of a slide 2 provided with punches 5. The movement of the slide 2 is transmitted to the blade 9 and the probe feeler members 27 teams of sprayers of cooling by means of a connecting rod 20, of a transmission lever 17 and the two arms 8 of the blade. The lever 17, slightly bend, bears by its thrust on a hollow 15 and is normally held against - latter by a spring 25 and by means of a rod 22. If a feeler member 27 encounters an obstacle, the press is placed at the stop. In the same time, the lever 17 is departs the thrust 15, by overcoming the force of return spring 25, which avoid any deterioration. Application of the punches at the bottom dead center. / p
