ii

Изобретение относитс к области мапшностроени , в частности, к конструкции кузнечно-прессового оборудовани .The invention relates to the field of mass production, in particular, to the design of press-forging equipment.

Известна ротационно-ковочна маилша, содержаща смонтированные в опорах корпуса обойму с сепаратором и роликами и шгашдель, в пазах которого установлены ползуны, а также Ззел сцеплени шпиндел с KopitycoM 1.A known rotary forging pipe containing a holder with a separator and rollers mounted in the supports of the case and a shaft, in the slots of which the sliders are installed, as well as the Zzel of the coupling of the spindle with KopitycoM 1.

В известной ротационно-ковочной машине недостаточно надежно обеспечиваетс фиксаци . цшиндел в корпусе.In a known rotary forging machine, fixation is not reliably ensured. zshindel in the case.

С целью устранени этого недостатка и повышени надежности узла сцеплени mnimдел и машины в целом, на наружной поверхности шпиндел выполнены зубцы, узел сцеплени шпшщел с корпусом выполнен в виде гребенки с зубцами, соответствующими зубцам щпиндел и винта, при этом в корпусе выполнены направл ющие дл гребенки и внутренн нарезка , сопр женна с резьбой винта, на винте выполнена п та, а в гребенке-подп тник.In order to eliminate this drawback and increase the reliability of the clutch assembly of the machine and the machine as a whole, the teeth are made on the outer surface of the spindle, the clutch assembly with the body is made in the form of a comb with teeth corresponding to the spindle teeth and a screw, while the body of the comb and internal cutting, coupled with the screw thread, is made on the screw, and in the comb-knob.

На обойме 1, несущей сепаратор .2 с роликами 3, жестко закреплен ротор 4, выполненный в ввде маховика, на цилиндрической поверхности которого имеютс зубцы 5. Зубцова зона, скрепленных в блок ротора-маховика 4 и обоймы 1, образует активную электромагнитную поверхность, обеспечива тем самым использование маховика в качестве массивного зубчатого ротора 4 асинхронного дугостаторного электродвигател .On the cage 1, carrying the separator .2 with the rollers 3, the rotor 4 is rigidly fixed, made in the inlet of the flywheel, on the cylindrical surface of which there are teeth 5. The tooth zone, fastened in the rotor-flywheel 4 block and the cage 1, forms an active electromagnetic surface, providing thereby using the flywheel as a massive toothed rotor 4 asynchronous arc-controlled electric motor.

Claims

The arcs 10 of the stator winding of the rotor 8 (flywheel) are mounted. On the frame of the machine with the necessary clearance relative to the toothed surface of the rotor 8. In the slots of the spindle 7 head part, as in guides, sliders 11 with tool 12 (dies) are installed, having the ability to return translational (radial) movement. The frame also has a spindle-to-body clutch assembly consisting of a rigidly fixed from rotation and axial displacement of the thread 13, with which the spindle 14 is attached. The spindle 14 has a hand drive 15 at one end and a comb 16 with teeth at one end 17, which can engage with the teeth 9 of the rotor 8 (flywheel) of the spindle 7, thus ensuring the locking of the latter. The braking of the rotor 4 (flywheel) and the cage 1 connected to it with the separator 2 bearing the rollers 3 can be provided with known braking devices, for example, with a face pneumatic spring brake 18, the Rotary forging machine, depending on the given mode, works as follows. The first mode of operation is the simultaneous rotation of the yoke 1 and the spindle 7. When voltage is applied to the winding of arcs 6, 10 of the stators of the asynchronous electric motors of the yoke 1 and spindle 7, the corresponding rotors 4, 8 (flywheels) are accelerated towards each other by a running magnetic field to the nominal speed . The rotor 4 rotates the carrier separator 2 connected to it with the roller 3, and the rotor 8, which is rigidly mounted on the shaft of the spindle 7, rotates the latter. As a result of the oncoming movement, the rollers 3 overlap the profile contact part of the sliders 11 and force the moving system (crawler 11 - tool 12) to move to the center of rotation of the spindle, i.e. to the forging axis. When this is introduced into the lead-in part of the tool 12, the workpiece is deformed by a certain amount. Since the tool 12 performs a complex movement with respect to the workpiece (reciprocating in the grooves of the spindle 7 and rotational), the workpiece is deformed over the entire surface located along the working zone of the tool 12, i.e. forging gets round shape. After the impact has been made and the profile contact part of the slide 4 is moved to 11 from under the roller 3, the centrifugal forces move the sliders 11 to the initial position, i.e. away from the center of rotation of the spindle. When the next roller 3 rushes onto the profile contact part of the sliders 11, the process repeats. The second mode of operation is rotation of the cage with the spindle 7 locked. To accomplish this mode of operation, you need to lock the spindle 7. To do this, use the spindle stopper handwheel 15 to the movement of the spindle screw 14, which, moving relative to the cutting 13, engages the teeth 17 of the comb 16 with the teeth 9 of the rotor 8 rigidly fixed on the spindle 7, thereby ensuring reliable locking of the latter. After the locking of the spindle 7 is completed, a voltage is applied to the arc 6 of the stator winding of the holder 1, and the holder 1 together with the separator 2 bearing the rollers 3 is 5 D {rotation). When the rollers 3 run over the profile part of the sliders And the radial movement of the sliders 11 (reduction) is carried out, similarly to the above. Since the spindle 7 is locked in this case, the POL35T1Y 11 with the tool 12 perform only reciprocating motion, thereby setting the square forging to or (with periodic rotation of the workpiece or spindle) a multifaceted shape. The economic effect of using a rotary forging machine is due to its increased reliability and ease of maintenance. Claims of the invention A rotary forging machine comprising a holder with a separator and rollers mounted in the housing supports and a spindle in which slots slides are mounted, as well as a spindle engaging assembly with the housing, characterized in that, to increase reliability, the outer spindle surface is filled the teeth, the clutch assembly between the housing and the housing are made in the form of a comb with teeth, corresponding to the 1st teeth of the pinch and screw; in this case, the guide has dies for the comb and internal wiring, coupled to the screw thread, the inte is performed on the first, and in the comb is a subtitle.
