Description

The present invention relates to a machine that straightens variables in a direction with kinks, first gradually increasing and then decreasing to zero.

FIG. Figures 1 and 2 show the proposed machine in two projections.

The workpiece 6 is installed between the clamps / up to the stop 2. The working surface of the clamps / corresponds to the shape of the workpiece 6. Each pair of clamps / is located in frame 5. When air is admitted to cylinder 5 (and released from cylinder 14}, for each frame, 3 rods 12 rotate crankshafts the levers 13, which cause the wedge 4. to lower, the ignition / fix the workpiece 6, and the frames 3 are centered along its axis. Then the air from the cylinder 9 is released, and the levers 13 are set to the middle position under the action of springs 17 and 18 wedge mi 4.

While the frame is being edited, 3 receive a reciprocating movement from the electric motor 27 via a text drive 26, a flywheel 25, an eccentric shaft 24, connecting rods 23, drawstring 21, sliders 20, and combs 19. Combs 19 have reciprocating movements

along the axis of the workpiece 6, synchronous with the movement of the frames 3. They receive from the shaft 24 through serrated pairs 29 -l 22 l fists 10. The depressions of the second are located opposite the projection of one comb. Therefore, the sliders 20 do not act on all the frames; k; and 3 simultaneously, but alternately through one on one side, then on the other.

The stroke length of the crawler 20 changes depending on the position of the eccentric supports 28 planted on the heels // and turned with the aid of the motor 7 through the worm gear 8. As this noBOipOra goes, the sliders 20 first approach each other and frequently strike the frames 3 variable reversals are made. of the blanks 6, then they are consumed and the bends are gradually reduced.

In order to remove the straightened workpiece 6, air is injected into the cylinder 14, while the levers 13, under the action of the outer rods 15 and 16, raise the wedge 4, and the springs 5 push the clips 1 apart. Before changing the workpiece, the engine 7 is turned off. During the shift, the cam gear 8 is in such a position that the comb 19 does not reach frame 3.

Claims (2)

1. A machine for dressing products with variable in the direction of kinks, gradually increasing to a certain maximum, and then decreasing to a complete cessation, characterized in that for making such kinks, moving across the product of the frame 3, which are on both sides under the action of sliders 20, are applied, driven in a return-and-step approach simultaneously in one direction and supplied with combs 19, moved back and forth along the product synchronously with by moving the sliders 20 to influence the latter on each frame 3 through one alternately from one side to the other. 2. Form machine pop. 1, but with the fact that, in order to fasten the product within 3, in each of them, two devices were applied across the body: there were two of them: the arms / under the action; wedges 4 moved by cranked levers 13 by means of separate for each frame intermediate between levers STAND; 12 and outer rods 15 and 16, dl. which are equipped with piston pneumatic actuators P and M ..
