Description

one

The invention relates to the IC of the field of automation of sheet metal stamping and can be used for automatic loading of presses with blanks from a package.

Devices are known for feeding strip blanks into the working area of the inpecca, 1 containing friction gripping bodies mounted on the base of a forward-moving moving carriage ic.

Such devices are not sufficiently productive due to the need for space (to disengage the gripping bodies in idle mode and refueling with the workpiece, which, in turn, complicates the gripping and feeding of the workpieces from the foot.

The aim of the invention is to improve the performance of the device and simplify the process of capturing and feeding the blanks from the foot.

For this purpose, the friction gripping bodies are made IB in the form of rolls, which are periodically rotating in the direction of blocking, from the fixed link drive element provided on the base of the device by means of periodic motion mechanisms located on their axes, which the proposed device is equipped with.

In addition, the drive link is made in the form of (rail kinematically connected with the mechanism. (Periodic motion, which is made in the form of roller sleeves overtaking.

FIG. 1 - the proposed device, a general view; in fig. 2 - the same, top view.

On the table 1, the Press is fastened with bolts 2, the base 3, “and which bolts 4 are reinforced with STAY1 5 with 1 MOVING carriage 6. On the last roller 7 and spring 8 are mounted.

At the ends of the carriage rigidly mounted

housing 9, in which the rolls 10 are installed, and in the movable lids // - rolls 12. On the axis of the rolls 12 there are overrunning clutches 13 and gear 14, which interact with the rack 15. With the help of bolts 16, axis 17 and spring 18, the rolls are one to the other, and for their direction, the support rollers 19 are installed in the cases. A copier 20 is fixed reciprocally on the press slide to move the carriage.

the magazine 22 is gripped by a pump 23, driven by B by a pneumatic cylinder 24 driven by a spool 25. The upper extreme position of the workpiece is delimited by a stop 26. To connect the suction to the atmosphere;

Shtyr 27 is provided, interacting with “Lanap 28.

The receiving rolls 29 are provided in the device, as well as the contact 30. The device operates as follows.

Pneumatic pneumatic cylinder supplied

to the workpiece and, capturing it, podimaet to its highest position. The walker reaches the 26. 26. grinding the B rollers, which rotate, run over and are molded with the Overrunning clutches. Further, isaroToiBxa is fed periodically under the stamp: according to the copier and the spring 8, which will send the workpiece to the yinopa in the stamp with a tension of 2-3 mm. Strip waste from logging enters the receiving rolls 29, which have a flaking surface.

In the case of blanking the workpiece, contact 30 closes an electrical power point, including an electromagnet (not shown in the drawings). Electro-Compnit, in turn, includes a spool 25 that feeds air into the pneumatic cylinder, causing the crais to take the next workpiece and raise her and the cycle is repeated.

Subject invention

Claims (2)

1. A device for supplying strip blanks to a working zone of a press containing a reciprocating moving carriage with friction gripping bodies installed on the basis of the bodies, characterized in that, in order to increase (productivity and simplify the process of gripping and feeding the blanks from the foot, the fricciol gripping bodies are made in the form of rolls periodically rotating in the feed direction of the zagot under the action of the kinematically installed on the base of the fixed link; associated with the mechanisms of periodic motion located on their axes. 2. The device according to claim 1, characterized in that the drive link is completed in the form of a rail, and the mechanisms of periodic movement in the form of roller couplings Obgoia. t-yw - i i
