Description

(54) DEVICE FOR TRANSFERING PREPARATIONS IN A CIRCLE

one

The invention relates to the mechanization of the punching industry and can be used in multi-station automatic presses for inter-operational transportation at high speed and under the conditions of influence on the device of a large amount of coolant and scale.

A known mechanism for the transfer of blanks along the arc l.

However, it cannot transfer workpieces around the full circle and in a polluted environment.

It is also known a device for transferring blanks in a circle, comprising a housing rotatable from the actuator with drive flares mounted therein for gripping the blank, made in the form of twin levers 2.

However, such a device is inertial and also inoperable in a polluted environment.

In order to eliminate these drawbacks, the body of the proposed device is sealed, and the drive of tongs is

a view of a drive shaft rotatable relative to the housing, located coaxially and inside the housing, and also mounted around the circumference of the rollers, carrying arms of pincers and gear wheels connected to the drive shaft, and the sectors in pairs with each other, and on one half of the rollers the sectors are fixed hard, but on the other - free.

FIG. 1 shows the proposed device, a general view; in fig. 2 - view A of FIG. one.

The device comprises a movable body 1 located in the center of a circle passing through the centers of the matrices and made hermetic. Rollers 2 are placed in the housing around the circumference; rigid gears 3 of which are fixed with the central shaft gear 4. The ends of the rollers coming out of the housing carry levers 5 with centering prisms for the workpiece rods. Two toothed sectors 6 and 7 are seated on the forks, with sector 6 being rigidly fixed on the roller, and sector 7 sitting on the hub. The hubs of the free-running sectors exit the housing and also carry levers with centering prisms. The levers rigidly fixed on the rollers, interacting through the toothed sectors with the levers fixed to the freely sitting toothed sectors of a number of located rollers, form in pairs the flares of the device.

The device works as follows.

In the initial position, when the flares are open and the workpieces are pushed out of the dies, the shaft-gear 4 is rotated at some angle relative to the housing 1 and the tongs are securely locked, clamping the rods of the workpieces. Then the housing and the gear shaft, rotating together, transfer the bolts to the following positions.

As soon as the blanks begin to push into the matrix, the gear shaft returns to the starting position relative to the body and the tongs open, skipping the head for 1X) goods. After that, the shaft-gear and the body rotate together to their original position, and in; the ends of the open clamps (centering prisms) are at this moment space) 1Y closer to the center and do not touch the heads of the workpieces protruding from the dies.

The combination of the drive of the uncoupling of the central gear shaft located coaxially and inside the hub of the movable body, as well as the placement of the hubs glueiiiiii coaxially and) and each other allows -; - X

to ensure a perfect performance and small inertial forces of the device.
