Description

The invention relates to the processing of metals by pressure and can be used for the single issue of blanks or parts in sheet-stamping or assembly lines.

The aim of the invention is to improve the reliability of the device.

FIG. 1 schematically shows a device for the single delivery of flat blanks, section A-A in FIG. 2 (variant D); figure 2 is the same, the view in the plan (option D); on fig.Z - section BB in figure 4 (option II); figure 4 - the device, the view in the plan (option I).

Device for the single issue of flat blanks (option I) includes the base10

a foot from falling through the failed window 2, and the rod 7 of the pneumatic cylinder 8 is extended.

During the return stroke of the rod 7 of the pneumatic cylinder 8, the described operation cycle of the device is repeated until the next workpiece 3 is issued when the cassette 5 reaches the leftmost position.

A device for routine delivery of flat blanks (option II) includes (FIG. 3 and 4) a base 1 with a failure window 2, made in the shape of the output blank 3, and also installed vertically coaxially with a failure window 2 with the possibility of full rotation of rollers 4 cartridge 5 s a gear ring 6 connected to the drive 7. In addition, in the base 1 (Figures 1 and 2) with a failed window 2, 15 of the Research Institute 1, non-rigid clamps 8 are mounted

made in the shape of the blank 3, as well as vertically mounted on the rollers 4 on the base 1 coaxially to the failure window 2 cartridge 5, having a cross-shaped cross-section corresponding to the configuration of the two cross tiles at an angle a and blank 3. In addition, the cartridge through the lever 6 and the rod 7 is connected with the pneumatic cylinder 8. On the base 1, the stop 9 is rigidly fixed, the free end of which is placed in the groove 10 of the cassette 5.

Flat blanks 3 are placed in the cassette 5 sequentially one above the other, with each subsequent turning laid at angle a relative to the previous one.

A device for the single issue of flat blanks works as follows.

In the initial state of the device, the cassette 5 is rotated, for example, to the extreme left position up to the stop 9 in the groove 10, and the bottom blank 3 keeps the stack of the laid parts from falling out of the through hole 2 of the base 1, the rod 7 of the pneumatic cylinder 8 retracted.

When the pneumatic cylinder 8 is turned on, the cassette 5 through the rod 7 and the lever 6 rotates in the direction of the arrow and on the rollers 4 in the cylindrical cavity of the base 1 to the extreme right position until it stops 9. The workpiece 3 is dispensed through the window 2. Next, the workpiece 3 is turned angle a holds the rest

cassette 5. The latter has a cross section corresponding to the contour of the two blanks 3, the axes of symmetry of which are rotated relative to each other around their center. A device for the single issue of flat blanks works as follows. In the initial state, the cassette 5 is mounted on the base 1, is in a position in which the bottom blank 3 keeps the stack of blanks from falling out of

25 failure window 2. In this case, the non-rigid clamps 8 are engaged with the cassette 5. When the drive 7 is turned on, the tape 5 rotates through a gear ring b, a step equal to the angle a, and then the drive 7 is turned off. In this case, the locking devices 8 are disengaged from the cassette 5 at the beginning of the turn and re-engaged at its end. The bottom blank 3 falls into the failure window 2, and the next blank 3 keeps the foot from falling out. In a subsequent rotation, the described cycle of operation of the device is repeated.

The application of the proposed device provides the possibility of issuing blanks with burrs along the perimeter to the processing unit, and blanks that are boxed.

In addition, there is the possibility of issuing blanks with different thicknesses and increasing the productivity of the device due to the absence of idling when issuing blanks.

When the actuator 7 is turned on, the cassette 5 rotates through the gear ring b by a step equal to the angle a, and then the actuator 7 is turned off. In this case, the clips 8 are disengaged from the cassette 5 at the beginning of the turn and re-engage when the end thereof is completed. The bottom blank 3 falls into the failure window 2, and the next blank 3 keeps the foot from falling out. During the subsequent focal rotation, the described cycle of the device operation is repeated.

The application of the proposed device provides the possibility of issuing to the processing machine the blanks with burrs along the perimeter, and blanks having warping.

In addition, the possibility of issuing blanks with different thicknesses and increasing the productivity of the device by the absence of idle speed in the issuance of blanks.
