摘要

1. Device for automatic racing presses, that being applied in those that have an eccentric drive shaft carriage, is characterized in that has at least one eccentric shaft area where a susceptible rotation bushing is located and provided with a cam mechanism of the outer circumferential surface of one end, while at its other end has an external toothing in linear correspondence with the practiced in another axial sleeve draft in the same eccentric shaft area and fixed with a key; leaving the teeth of the two axial sleeve draft in the same area eccentric shaft and fixed with a key; leaving the teeth of the two sleeves, in engagement with the toothing of a locking piece, which has a central region of its dentanda periphery provided with a circular recess smooth and a length equivalent to the tooth splined sleeve shaft, which It allows relative unlocking of both sleeves to be shifted at will and axially locking part by two diametrically opposed discs attached to the ends of respective rods belonging to a tire to be disks fitted on a peripheral central recess of the locking cylinder , having the corresponding microswitches connected to one of the disks and shafts, with optical signal into an electronic board, which exhibit the locking and releasing the sleeve provided with eccentricity; further provided, in a non-eccentric shaft area, a circular piece concentrically to it, situated in contact with the front face of the sleeve provided with eccentricity, which has a front and radial notch to the same side of the bushing, which is guided a prismatic part secured to the cap by a screw, having a point of the periphery of this round piece, a hole confronting with an electronic detector fixed to the bedplate recorded in the panel the eccentric position of the axis, in its deadlocked higher; also having a third bushing fixed pressure, at the free end of the eccentric shaft, which has no eccentricity, on the periphery of which are disposed a plurality of holes whose position in its rotation, is detected by an electronic detector, fixed to the bedplate , when confronted with him, each corresponding one of these holes a jump different and predetermined stroke, signaled on a display of the electronic reading, taking place the automatic switch by a gearmotor group causes rotation dle eccentric shaft, while the cap left without rotation, until the desired career. 2.
