Abstract

Use: relates to cold pressure treatment of metals in the manufacture of ring blanks. The invention: the device contains at least three mechanical tubular arms, two of which have independent drives of horizontal and vertical displacement mechanisms (actuators made in the form of beams with protrusions and depressions placed in longitudinal grooves of tubular arms rigidly mounted in the body so that beams with protrusions and depressions at the positions of acceptance of the curled split billet rings and issuing sequentially have the ability to connect with horizontal displacement cylinders with the T-shaped grooves in the beams them with adequate projections of rods. Stocks vertical displacement cylinders kinematically beams can bind to the lever-roller drive system of said vertical movement mechanism. 1 ZP f ly-8-yl. with C

Description

The invention relates to the field of cold metal forming and can be used in the manufacture of ring blanks.

The aim of the invention is the expansion of technological capabilities through the transfer of curled split annular blanks.

Figure 1 shows the device, a general view; figure 2 is a view of A in Fig.1.1 in Fig.Z - section BB in Fig.2; Fig. 4 is a sectional view BB in Fig. 1 (the cap is removed); figure 5 - arm, longitudinal section; figure 6 - section GG in figure 5; figure 7 - cross-section dD in figure 5; on Fig - section EE of Fig.6.

A device for accumulating and moving ring blanks contains a rack 2 mounted on a base 1, a housing 3 mounted on a rack can be rotated relative to it on rolling bearings 4 and 5, a housing turning mechanism 6 mounted on a base 1, arms 7 mounted on a cantilever equipped with mechanisms for the separation and uniform installation of the workpieces on the hands, each of which is made in the form of a comb strip 8 mounted on the arm with the possibility of reciprocating movement in the horizontal vertical plane, moving said comb assembly comprising a roller 9,

levers 10 and 11, hinged on the arm by means of axles 12, interconnected by hinge joints 13 and 14, and a pusher 15 in contact with lever 11, a plunger 16 connected to a comb strip 8 using cylindrical segments 17 and an axis 18, the plunger 16 is provided with a stopper 19. The movement of the rails is made in the form of a cage (block) 20 with underwater channels 21 in which four power cylinders are placed: the top 22 are double acting, the bottom 23 are single acting, and the drive for moving the rail is rigidly mounted on a rack 2 and located in the building ce. The drive of the rail movement is controlled by distributors 24 mounted on the base 1 and connected to the channels 21 by pipes 25.

The casing 26 is rigidly fixed to the bottom of the casing 3, the casing 27 at the top has bores 28 for attaching the arms, and the top is closed by the lid 29. The hand 7 is made in the form of a hollow pipe with a longitudinal groove, and the slatted bar 8 is located in the longitudinal groove of pipes.

The body rotation mechanism 6 comprises an electric motor 30, a coupling 31, a gearbox 32 and a control unit 33 connected to the gearbox by a chain 34. A gear 35, rigidly fixed to the gear wheel 26, is rigidly fixed on the gearbox.

A device for storing and moving the ring blanks works as follows.

In the initial position, the rods of all cylinders 22 and 23 are chucks, which makes it possible to turn on the mechanism 6 for turning the body and to install two hands 7 opposite the rods of cylinders 22 and 23, while the rods of the upper cylinders 22 enter into the T-shaped groove 36 of the plunger 16, rods the lower cylinders 23 become coaxially the pushers 15, and the third arm is placed in a non-driving position. Since all hands 7 are fixed on the case 3 with equal angles between them (for example, 120), when turning to this angle, two hands will be in interaction with the rod moving drive, one without it. Including the cylinders 22 and 23 in a certain sequence, one can either dial a ring with a step equal to the step of the depressions of the slatted strip 8 (dialing position), or issue one for the next operation (discharge position).

A pair of cylinders, which interact with this hand, work in the dialing position. The upper cylinder 22 is turned on and the strip 8 moves along the rollers 9 from

the center, then the lower cylinder 23 is activated by the action of the lever system of the roller 9 and the strip 8 rises up the bottom of the cavity to the level of the arm (pipe). Further

the cylinder 22 is switched and the bar 8 is moved to the center of the device, then the cylinder 23 is switched - lowering the rollers 9 and the lever system. For example, in the ring set position

0 arm rings coming one by one from the previous operation. The upper cylinder is turned on and the strip 8 is moved from the center, the lower cylinder is turned on and the rollers 9 and the strip 8 are raised to align

5 above the hand, grabbing into any groove ring. The upper cylinder is switched and the strip 8 with the ring is moved to the center. The lower cylinder switches and the strap 8 descends below the pipe.

0 Next, the cycles are repeated until the full set of rings on the hand.

At the dispensing position of the rings one by one for the subsequent operation, the lower cylinder and rollers 9 and bar 8 are raised above the arm. The upper cylinder is turned on and the strip 8 moves along the rollers 9 from the center, moving all the rings to a step. The front one gives out for further processing. The lower cylinder switches and the rotors 9 and bar 8 descend below the pipe. The upper cylinder is switched and the strip 8 is moved to the center without rings.

Then the cycles are repeated until the rings are completely dispensed one by one.

5 After a full set of rings on the hand at the dialing position and issuing the rings at the dispensing position, the movable part of the device is rotated by an angle, in this case 120 °, and work continues,

0 The hand without a drive (as if spare) in this case is the position of visual control of the position and quality of dialed rings.

All operations on the recruitment, issuance of rings
