Description

In order to protect the worker’s hands from the gift by the punch, in case the worker doesn’t have time to remove them, we offer a device consisting of a safety net OR shield mounted on a spring lever with a bar with a recess for the spring stop. With the help of a ti g, a spring-loaded pedal acts on the lever, the over-, covering pedal of the machine, or this latter directly, is supplied in this case with a spring.

In the schematic drawing of FIG. 1 is a side view of the proposed fixture; FIG. 2 - front view; FIG. 3-.6 are the various positions of the adaptation mechanisms.

The safety shield (grid) A is integral with lever B and lowered in front of each punch-on strike.

The bracket B is attached firmly to the table G of the punching machine and has a structure depending on the shape of the latter. The stroke of the lever B is ogr nchen when lowering the contact of the shield A with the table G, and during the raising with the collar D. Through the lever B passes the ha ha D on which the abutment is put on And, spring “F and two spherical pillows 3, of which

mounted on the t e of E still, and the top sits freely. At the bottom, the hinge E is connected by a hinge to the pedal K held in the raised position by spring L. To the lever B the bar M is pivotally attached, which in the raised position depresses the spring stopper S, and in the lowered position allows it to jump into the slot OR .

In order to set the correct position of the lower spherical cushion 3 and the stop M, they are threaded; after their final adjustment, they are screwed with nuts and counter-nuts or cotter pins. The degree of pressing of the spring G is regulated by a nut sitting on the upper end of the string E.

When stamped item. put on the matrix, the worker presses the pedal E with his foot. Then, through lever E, lever B with shield A is lowered with a part of its own weight, and partly due to pressure from the spring J. The IG spring itself does not compress, and the spherical pillows 3 remain in contact with lever B (Fig. 5). Together with the latter, the plank M is also lowered, sliding in the special groove of the bracket B. At the same time,
