The invention relates to the processing of metals by pressure, in particular to the designs of multi-operation rotors.

The aim of the invention is to increase productivity.

Figure 1 shows a multioperational rotor, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - multioperational rotor with a hydraulic drive of the sliders, a longitudinal section.

The multi-operation rotor contains a drive shaft 2 mounted on the frame 1, a disk 3 rigidly connected to the shaft, two drums 4 and 5 located on both sides of the disk, technological positions evenly spaced around the rotor circumference, and a mechanism for transferring the workpieces to 6 seconds.

one position on the other. I

Each technological position

includes instrumental unit 7 and two sliders 8 and 9, installed in guides, 10 and П, filled in drums 4 and 5. Tool block 7 consists of matrix 12 fixed on disk 3 and puason 13 coaxial with it and ejector 14, respectively, associated with sliders 8 and 9. The main and additional technological positions are located in concentric circles 15, -15 and form radial rows 16 between them.

The rotor rod 20 interacts with the cam 22 and in the transfer areas of the blanks 6 transfers them in the radial direction along the technological positions from the pipe 1 of the accumulator 33 to the puller 31. Thus, the sequential processing of the blanks is performed in each radial row of technological positions. During one revolution of the rotor, as many blanks are machined as there are radial rows of technological positions in the rotor. 2 hp f-ly. 3 il.

The number of technological positions in each row 16 corresponds to the number of concentric circles, the Slides 8 and 9 are connected to a reciprocating drive, which can be performed either in stationary B1. units of the copiers 17 and IB, mounted on the station 1 1 coaxially to the drums 4 and 5, or in the form of power cylinders 19, for example hydraulic cylinders connected to the said sliders.

The mechanism for the transfer of workpieces 6

one position to another is made in the form of rods 20 installed along the corresponding rows of 16. blocks 7 and placed with the possibility of radial movement in the guides 21,

made on the disk 3, and in contact with the rods 20 of the annular cam 22 connected to the frame 1 and cover the disk 3. Each rod 20 is equipped with a carriage

23, installed with the possibility of longitudinal movement and carrier grips 24 "., Whose number is chosen one more than the number of technological positions in the corresponding row 16, and the distance between adjacent grips is equal to the step

H between the matrices of this row. one

Two are installed on the rods 20

cylindrical springs 25 interacting with annular collar 26, executed on the middle part of each

the rod 20, and the different ends of the carriage 23. On the disk 3, the stops 27 and 28 are fixed, arranged in twos in concentric circles with the possibility of alternately interacting with the different ends of the carriages.

The working surface of the cam 22 is made in the form of alternating protrusions 29 and valleys 30, the distance between which is chosen slightly longer than the distance L N between the grippers. The puller 31 fixed to the base 1 is placed outside the disk 3 to remove the finished work pieces 6. At the top of the shaft 2, a hopper 32 is fixed with storage tubes 33 located in radial rows I 6 of technological positions and offset from the extreme matrices I2 by a distance L N.

The rotor works as follows

When the shaft 2 rotates the workpiece 6 from the hopper 32 enters the storage tubes 33. At the loading position, the rod 20 moves into the depression 30 of the cam 22, and the carriage 23 approaches the shaft 2 and comes into contact with the stop 27. During the contact of the carriage 23 with the stop 27, one of 25 is compressed, compensating for errors in the rod stroke, and the grips 242-., Relative to the 16 matrices 12 and gripper 24, located in the radial row 16, are aligned with the storage tube 33. The blank from the storage tube enters the gripper 24 . During the further rotation of the rotor current 20 moves from the depression 30 to the protrusion 29 and the carriage 23 is removed from the shaft 2 of the rotor into contact with the other abutment 28 and is set in the unloading position of the preforms grippers matrix. At the end of this stroke, a compensatory compression of the other spring 25 and coaxial installation of the grippers 24-24), relative to the matrix 16 arranged in a row 16 and the gripper, takes place in the zone of action of the puller 31. After that, the slider 8 with the punches 13 makes a reciprocating the result of which the preform 6 located in the gripper 24 is fed into the matrix I2 of the first concentric circle 15 and undergoes the first technological operation.

Then, the sliders 9 with ejector pads 14 and the stock are actuated.

ki 20 with carriages 23 are returned to the loading position. The working surfaces of the cam 22, interacting with the rods 20 and the stationary 5 "

blocks copiers 18 interacting

with ejectors 14, are designed in such a way that they provide simultaneous movement of these

10 cocks and pushers at the beginning of the zone of unloading blanks from the dies into the grippers, and at the moment when the ejectors 14 come into contact with the blanks 15 located in the dies 12, 6, the radial movement of the rods 20 stops and their grips are aligned with the corresponding matrices.

As a result of the reciprocating motion of the ejectors 14

provides pushing of the workpiece 6 from the matrix 2 of the first concentric circle 15, to the grip

.

24J. Simultaneously with pushing

25 of the workpiece 6 into the gripper 24, the gripper 24 located under the storage tube 33 is loaded. During the next movement of the rods 20 to the unloading position, the raw billet 6 arrives from the bunker 30, 32 is transferred by the gripper 24, to the first concentric circle 15, and the blank is located in the gripper 24 of the predecessor, after the first operation, the circular workpiece 15 is transferred undergo appropriate operations, etc. The finished billet 6 is captured 24, in process

40 6GO movements to the unloading position is transferred to the zone of action of the puller 31, where it is removed from this gripper and enters the container for collecting parts. Thus, in the proposed

45 rotor occurs the simultaneous transfer of the processed blanks in all radial rows of technological positions and as a result

I

.-one turn is provided by unloading 50 several finished billets, the number of which coincides with the number of radial rows of technological positions,
