Abstract

The invention relates to the processing of metals by pressure, namely to ancillary equipment for forging and pressing shops, and can be used to manipulate forgings during their forging. The invention makes it possible to increase the reliability of the tick grip by facilitating the switching of the controlled latch. In this control, an end cam cam coupling is inserted in the control valve, consisting of half coupling (PM) 12, fixed with two shoulders 10 and pillars 11 in the fixed housing 2, and PM 33, connected to the axis 29 with a rotatable housing (PC). The latter includes satellites 30 meshed with a ring gear 18 of the mouthpiece 17 and a crown wheel 31 placed between a disk 9 of a controlled retainer and a non-rotary casing 2. When the switching drive 6 of the PM I2 is engaged, it engages with the PM 33. The PC is fixed relative to the fixed case 2. When the switching drive 6 is disconnected, the PM 12 is disengaged from the tiM 33, and the crown wheel 31 is pressed with the help of the disk 9 of the control clamp to the stationary case 2.

Description

The invention relates to the processing of metals by pressure, namely to ancillary equipment of forging and pressing shops, and can be used to handle forgings during their forging.

The purpose of the invention is to improve the reliability of the tick-borne gripping of a forging manipulator.

Fig. I shows a tick-borne grip, a general view; figure 2 is a section aa in figure 1 (Kouf kuffa linked); on fig.Z - the same, the cam clutch is disengaged.

Tick-borne gripping of the forging manipulator of the torus contains a rotatable 1 fixed 2 body. The fixed housing 2 is rigidly fixed to the frame 3 of the arm of the manipulator with the help of segments 4 and bolts 5. It contains a controlled clamp in the form of switching actuators 6 with springs of 7 t g 8 connected to a pressure disk 9, two shoulders 10, swinging on racks 11 and pivotally connected to one end with 8 and 8, and the other with a rotary clutch 12 of an end cam clutch. The swiveling tick body 1 is fastened on one side with a bearing 13 and an outer ring 14 in a stationary case 2, and on the other side with a bearing 15 and a gear wheel 16 on the mouthpiece 17 of the manipulator trunk. The gear wheel 16 has a cylindrical 18 and a tapered 19 gear rims and is fixed on the mouthpiece 17 of the trunk with an end key 20. On the swiveling housing 1 there is a clamp and 21 clamps with driving rollers 22, a node connecting the clamp mechanism with levers 23, the bearing 24 with mounted on it and rigidly connected with each other bevel gear 25 and a gear sprocket 26, as well as chain drives 27 and 28. Bevel gear 25 engages wheels 16 with a bevel gear 19 16. Axes 29 in the swivel housing 1 have satellites 30 that enterengages with a crowned wheel 31 having friction linings 32 and with a cylindrical toothing 18, wheel 16, and pivot coupling half 33, the end face cam coupling. Zagotogzha 34 clamped in the drive rollers 22 levers 21.

Tick capture works as follows.

In the mode of rotation of the grip around the longitudinal axis during the operation of turning the workpiece, the switching actuator 6 is switched on (Fig. 2). The springs 7, acting through the ti 8 on the disk 9, press the crown wheel 30 to the ring 14, excluding its rotation relative to the fixed case 2. The unremoved cam coupling half 12 connected through two levers 10 s of the t 8 8 swinging on the racks I1 is removed from the engagement with the rotary cam half coupling 33. When the drive of the rotation of the grip is engaged, the rotation of the mouthpiece 7 through the gear wheel 16 is transmitted to the satellites 30, which, by obeying the toothed crown of the crown wheel 31, communicate the rotation of the rotary body 1 together with the clamped rollers 22 levers 21 billet 34.

A switching actuator 6 is switched on to transfer the tick capture to the rotation mode of the workpiece around the vertical axis (draft operation). As a result of the movement of the piston actuators 6, the switching gear 8 and the disk 9, the crown wheel 31 is disengaged, and the non-rotary cam half coupling 12, the half a movement from the 8 double-arm levers 10 connected to it, engages with the rotary cam half coupling 33 ( FIG. 3), excluding the rotation of the axes 29 of the satellites 30 and the rotary body 1 relative to the fixed body 2.

When the rotational drive is engaged, the rotation of the mouthpiece 17 is transmitted through the bevel gear 19 of the wheel 16 to the bevel gear 25 and the sprocket 26, and from the latter by chain gears 27 and 28 to the driving rollers 22 and the workpiece 34. The satellites 30 meshed with the cylindrical a gear ring 18, wheels 16, rotate on axles 29 and impart free rotation to the crown wheel 31.
