SU35532A1 - Screw die for screw cutting - Google Patents

Description

In the existing screw die openings of Bachi under the action of springs with dies with the screw stop at the end of cutting, dies are opened by removing any part from the coupling. In the proposed invention, a U-shaped plate connected to the moving part of the screw die with the help of moving pins serves for this purpose. In FIG. 1 shows the plan of the screw clamp in the working position; FIG. 2 same with open dies; Fig, 3 side view of the screw die.v

Between the two fixedly fixed on the rods x 9, the pillows 1 and 8 are placed movably. Power 5, with a die 10 secured in it. To a non;;: U-shaped plate 7 with cut-outs on the ring for coupling with studs 3, npir fixed to spring stop 2 is attached to the cushion 8, the action of the screw block is as follows. Feed the screw die to the sharpened bar and rotate the bar or screw die one relative to each other), threading is performed until the bar to be cut rests on the stop 2. With further rotation the stop 2 and with it the studs 3 move a little away from part 5 and last, freeing coupling with the plate 7, moves away under the action of the springs 4 - from the stationary support 1, and at the same time the plates 1 and 10 will also disperse. To bring the screw die to the working position, it is necessary to press the rod 6 associated with the moving part 5 and the studs 3 will enter in the notches of plate 7 by the action of the spring abutment 2.Predmet izobret.eni.

A screw-die for cutting video clips with the use of dies self-expanding under the action of springs with a screw stop at the end of cutting, characterized in that in order to keep the dies in the working position, the U-shaped plate 7 connected to the movable part 5 by means of pins 3 , movably connected with spring support 2.
