Description

The invention relates to an iK device for producing articles by pressure treatment of metals.

The known device for the manufacture of serpents 1-рд; springs, containing a rotating FROM (Cam shaft with a drum located inside its sliding rollers and a carriage with flexible crimps, as well as a removal mechanism.

The purpose of the invention is to increase productivity and ensure the possibility of bending the workpiece on the edge.

This is achieved by the fact that the i4To device is equipped with a rotating disk cam with a bevel mounted inside the drum and interacting with the axis of the rollers radially located inside the drum as well as rigidly fixed to the frame and the segments covering it. With this, the mechanism for removal of the finished springs is made in the water of a gear wheel rotating on its bed rotating with its pins.

FIG. 1 shows a diagram of the machine and the cut IO A-A; in fig. 2-5 - technological nepexioinoB circuits.

The machine consists of a shaft / with cams 2 and 3, interlocking, modifying through levers 4 and 5, respectively, on the carriage 6 with two pins MI 7 and; on the shaft 5. On the shaft there is a reinforced lever 9 with a dog 10 and a disc fist // located Inside the drum 12 there is a roller 13. On the shaft 14 with the drum 12 there is a fixed ratchet (Wheel 15, in the separating hole of which a retainer 16 enters.

The gear wheel 17 is kinematically connected with the drum 12 with cylindrical bristles 18 and 19. Above the drums 12 with a gap larger) tape, next to the carriage 6 is reinforced segment 20. The non-operating area of the drum 12 covers the segment 21 holding the rollers 13 from falling out) 1 and mounted on the frame 22.

The machine works as follows. The end of the tape passes skrytr 1m 7 of the cuff 6 and is fixed between the rollers 13 of the drum 12. When the shaft rotates from the cam 2 through the lever 5, the shaft 8 is in motion.

When the shaft 8 is rotated clockwise, the disk cam 11 advances the roller 13 from the drum 12 in the bending area by an amount equal to the thickness of the tape, and the lever 9 with the pawl 10 rotates one division.

When the shaft 8 is rotated counterclockwise, the pawl 10 turns the ratchet dividing wheel 15 one division. The latch 16 provides the exact position of the ratchet dividing wheel. 15. Together with the ratchet dividing wheel 15, sitting on

the shaft 14 rotates the drum 12 with the rollers 13. Thus, when the Cam 11 is rotated counterclockwise, the drum 12 with the rollers rotates in the same direction.

Then, from K | Ulachka 2, through the lever 4, the bake b with the pins 7 is fed up, the bending tape (see Fig. 5), etc. The tape in the bending zone is limited in thickness by the cylindrical surface of the drum from one side by segment 20 and the carriage 6 - with another. The gear wheel 17 rolls around the drum 12, the rollers 13 roll into the body of the drum. This ensures the removal of the finished flat serpentine springs from the drum 12 bevel segment 21.

. Subject invention

An apparatus for making serpentine springs comprising an i6 T mounted on a shaft

rotating drum with movable rollers placed in it and a carriage with bending pins, as well as a mechanism for removing the finished spring, characterized in that, in order to increase productivity and ensure the bending of the workpiece on the edge, it is provided with a drum inside coaxially with it a rotating disk cam, a clod with a bevel interacting with the OSJMI of the EXTENDING rollers radially located inside the drum, and also rigidly fixed on the frame and grabbing it with a gap for the passage of the tape, with is ready removal mechanism is designed as a spring-mounted frame, rotatable about its axis a toothed 1kolesa interacting with a bending carriage placed on pins. 13 20 7
