The invention relates to mechanical engineering, in particular to technological rotors with automatic tool change without changing tool blocks in rotary machines and lines.

The aim of the invention is to increase productivity by providing automatic tool change in the process rotor without changing tool blocks and stopping the machine.

FIG. 1 shows a technological rotor, a general view; in fig. 2 - then

top view; in fig. 3 - section A-A in FIG. 2; in fig. 4 - roller sweep with screw grooves; in fig. 5 is a section BB in FIG. 3 | FIG. 6. —B-B section of FIG. 3

The rotor contains (Fig. 1, 2) drive shaft 1, on which drum 2 with drive sliders interacting with ring 4 and (for perception of technological efforts) end 5 cams, block holder 6 with tool blocks is mounted 7, consisting (Fig. 3) of the housing 8, in which the tool kit is mounted in the form of a piercing punch 9 and a die 10, a removable sleeve 11, Sun. The working area is divided into working and idle sectors with angles "t chY.

To automatically change tools without changing tool

Punch hole occurs. Then, the M 10 is retracted and the product is removed. Exit P 9 is monitored on a product basis. The presence of an opening in the product is monitored by a photosensor. The signal about the absence in the product 26 of the hole is transmitted through the electro-automatic system to B. 17. As a result, the driving slider 3 causes the B 17 to rotate around its axis at an angle equal to the pitch of the screw grooves to the B 17, and thereby turn the turret disk 15 and set working position new P 9. 2 z. p. f-ly, 6 ill.

The rotor is additionally equipped at each position with the cyclic rotation mechanisms 12, an automatic control of these mechanisms by an electromagnet 13, rigidly mounted in the return code sector with an angle of cL and electrically connected to a collector 14 mounted on the shaft 1, and each tool unit 7 is equipped an additional element in the form of a revolving disk 15 with perforated punches 9 fixed in its sockets and kinematically connected to the corresponding mechanism 12 of a cylindrical rotation through gearing with gear 16.

The mechanism 12 cyclic rotation is made (Fig. 3, 6) in the form mounted in the block holder 6 with the possibility of rotation around its axis of the roller 17 and the lever-clamp 18, rigidly mounted on the block 1-9 drive slide 3, with one end of the roller with screw grooves 20 arranged so that the straight end 21 of one groove is coaxial along the straight start of post 22 of the subsequent groove (the number of grooves 20 depends on the gear ratio of the gear wheel 16 and the number of piercing punches 9) Eski is connected (via gear 16) with a revolving disk 15. One end in the form

the tooth 23 of the locking lever 18 interacts with the screw grooves 20 of the roller, and the other end with the automatic control unit 13.

Technological rotor operates as follows.

The work of the rotor is performed in the process of its continuous rotation synchronously with the transport loading 24 and unloading 25 rotors. The loading rotor 24 in sector jb feeds piece 26 to the tool blocks 7 of the rotor. In sectors oi and o6, a technological operation is performed, after which, in the sector, the products are also individually generated from instrumental blocks by means of an iCTBOM discharge rotor 25.

After the product 26 is fed into the receiving part of the block, the matrix 10 moves upwards and enters the product through the drive slider 3, which first interacts with the cam 4, then interacts with the end cam 5, presses the bottom of the product to the punch 9 and punches holes in it.

The waste is removed through the central hole 27. Thereafter, the die 10 is retracted to its initial lower position, and the pin 28 retracts the removable sleeve 11 at the same time, which with its shoulder 29 removes the product from the punch 9 which is picked up by the unloading rotor 25 and removed from the block.

At this time, the mechanism 12 of the cyclic rotation of each position remains stationary, since the locking lever 18 is in the off position (the tooth 23 of the lever is retracted (Fig. 6) and does not interact with the helical grooves, and the slide blocks 3 with the pads 19 perform a return translational movements. This is how each position of the rotor alternately operates until the breakdown punch 9 is broken (broken) on one of the tool blocks.

The fact that a punch punch fails at one of the blocks is recorded over the product. The presence of openings in the articles is monitored (Fig. 2), for example, by a photosensor 30 fixed stationary in the transport path of the articles by the discharge rotor 25.

The photosensor signal that there is no hole in the product is transmitted through

the electro-automatic system to the electro-collector 14, and then to the electromagnet 13, the magnetic field of which interacts with the locking lever 18 passing past the shoulder 31, instantly moves towards itself, which introduces the rachaga-lock tooth 23 into the upper straight section 21 of the screw groove 20 of the roller 17 to interact with the movements of the drive slider 3. As a result, the drive slider 3, in the sector to reverse, causes the roller 17 to turn around its axis by an angle J equal to the step t of the helical grooves 20 (Fig. 4), than turn on this angle turret disk 15 and set the new perforating punch tool assembly BFP axis 9.

In the sector, the locking lever 18 of this position returns to its original non-working position by engaging his shoulder 31 with a fixed element 32 (Fig. 2), and the technological rotor continues to operate normally until the next tool change.

In this way, a tool change is made in any tool block at any time without changing the block and without stopping the machine. When the entire tool stock is consumed in the tool block, the rotor (machine) is stopped to replace the tool block.
