Description

Known vertical press machines for stamping no; ioc, coming from a bag laid on a lifting table. The strips are individually lifted out of the bag and shifted to the press by means of pneumatic suction cups. Further filling of the alternate strip into the transfer mechanism through the stamp is performed using tick-borne feeds, which seize the front edge of the hollow and lead it into the opened rolls to capture the transfer mechanism.

Strict interaction of mechanisms is ensured by mechanical connections in known automata. This complicates the design of the automaton, requires the introduction of additional tools and does not provide stable operation, since with such a scheme for filling the strip it often happens that two lanes are caught, which leads to rapid wear of the punches.

In the proposed automatic feeding scheme, a package of step 1 is eaten on a detachable table, which rises automatically as the workpieces are consumed. The strips from the bag are gripped by rubber pipes (without vacuum) and transferred to a hard stop, where the front edge of the strip is raised by a separate suction cup and placed on the new stops that support the next strip at the level of the feed to the press working area. The mechanisms for further movement of the strips are made in the form of opening clamps, stopped by stops, which determine the magnitude of the feed stroke.

To ensure the capture of only one band and the accuracy of feeding, the suckers are located in the middle of the groans and an additional suction mechanism is used to lift the front end of the strip fed from the foot into the H1 plane. In order to pick up and hold the raised strips, the mechanism is equipped with paws, which fold upwards on the axes. Next, the strips are captured by the GoTavnoy, for example, the tick-borne, by pressing.

FIG. 1 and a diagram of the automatic feed punching press; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow 5 of FIG. one; in fig. 4-lift table; in fig. 5 captures in the h; Indoor position: in FIG. b - grips in the open position.

D 124914The separation of the band from the packet and its transfer to the desired position occurs as follows. The suction / strip is perched in the middle, bends and moves with the air cylinder 2 until it stops 3. This iiepeMcnieHiic /.o set lasts half the time it takes to cut the entire strip. At. For example, for an iron rotor and a stator (thickness 0.5 mm), and a significant rise in suction cups (50-100 mm), the strip bends strongly and other bands adhering from the bottom fall. Then, the suction cup 4 is lifted from the air cylinder 5 of the front edge of the strip, which lies on the pivoting stops 6, which are at the level of the action of the grippers of the transfer mechanism. After that, the opened grippers 7 run over the strip, close and move the strip during the reverse movement. The transfer mechanism receives a reciprocating motion by means of a gear-rack mechanism 8:

On the horizontal slats 9, the housings 0, in which the clamps 7 with jaws are mounted, are movably mounted //. When the racks of the gear-rack mechanism 5 and, therefore, of the housings 10 are moving to the right, the grippers are moving open, thanks to the step-shaped finger 12. After reaching the unor IS, the body with the grips stops, while the rail 9 with the fixedly mounted finger 12 continues to move . The transition is a step-down diameter of the stepped blade, the grippers are closed by means of a spring 14 and the strip is clamped with jaws 11. For a reliable sim, the bands of the sponge 11 are notched. When moving the rails with grippers from left to right, the latter interchange the strip on the cutting pin. Move to the stop / 5, the grips open with a finger and release the strip. The opening of the grips occurs up and down from the level of the matrix; consequently, during the reverse movement of the grippers, they do not knock down the strip. The strip during the passage through the stamp is slightly pressed to the mirror of the stamper by plate springs 16. After passing the two positions of the stamper, it is moved by the claws, the similar claws 7, which pull the strip to the last notch.

Work of captures to Zpor provides high precision of giving of a strip. A carriage with Nrisos is mounted on a pivoting frame 17, represented by Yun1, it is a hinged four-tiered, which is turned in turn out of the working area. Such an automaton loading scheme significantly reduces the production area required for the operation of the machine. In order to increase the height of the loading bag and increase the productivity of the machine, the table of the loading device 18 is made lifting from a separate electric motor, which is turned on from the pulse counting relay, depending on the number of automatic moves made, and is disconnected.
