Description

one

The invention relates to the processing of metals by pressure and can be used in the automation of stamping production.

A revolver device for feeding piece blanks is known, containing, on its base, a rotating disk with sockets for blanks 1.

However, this device does not provide stable operation and accurate fixation.

It is also known to have a revolving device for feeding piece blanks, containing a transport disk mounted on the base with workpieces and slots on its upper end, a disk turning mechanism and retainers fixed in the housing in the form of keys with bevels interacting with disk 2.

However, this device is not reliable enough.

The purpose of the invention is to increase the reliability of work and accuracy of fixation.

This goal is achieved by the fact that in a revolving device for feeding piece blanks containing a transport disk mounted on the base with slots for blanks and grooves on the top

its face, the disk rotation mechanism and the clamps fixed in the case in the form of keys with bevels interacting with the disk, the keys are placed in the case so that they can be rotated around the axis installed in it and spring loaded, the case is provided with a spring-loaded clamp holding one of the keys above the disk when it is unlocked and to release this key during rotation of the disk, while one of the keys is set to interact with its bevel with the bracket stop.

FIG. 1 shows the device, a general view; in fig. 2 - the same plan view; in fig. 3 is a section A-A in FIG. 1; in fig. 4 shows a section BB in FIG. 2

Claims (2)

The revolving device for feeding piece blanks contains a transport disk 1 rotating on axis 2 and having slots 3 for blanks and grooves 4 at its upper end. In case 5, clamps are installed on axis 6 and speed 7, keys 8 and 9 pressed to disk 1 by springs 10. Bracket 7 is on one side of collar 11, and on the other side is abutment 12. Bracket receives movement from spring 13 and abutment 14. On buttons 8 and 9, flags 15 and 16 are set, which interact with switches 17 and 18, included in the installation scheme. In key 9, bevels 19 and 20 are made, the bevel 19 is kinematically associated with the disk 1, and the bevel 20 is connected with the stop 12 of the bracket 7. The device operates as follows. In the initial position, the keys 8 and 9 are inserted into the groove 4 of the disc 1. When the stop 14 is moved downward, one end of the key 8 through the pusher 21 rotates about the axis 6 and simultaneously lifts its other end above the disc 1. In this case, the collar 11 of the bracket 7 comes under the action of a spring 13 under the key 8. And holds it in a raised position, and the stop 12 is above the bevel 20 of the key 9. The checkbox 15 opens the limit switch 17, preventing possible movement of the stop 14. When re. Moving the stop 14 to the upper position, the disk 1 is rotated, the wall of the groove 4 presses the bevel 19 of the key 9 and disengages it, and with the bevel 20 returns the stop 12, and at the same time the bracket 7 returns to its original position, releasing the key 8. At the same time 16 opens the limit switch 18.. Upon further rotation of disk 1, keys 8 and 9 alternately fall into groove 4, locking the disk, flags 15 and 16 turn on limit switches 17 and 18 and the cycle repeats. In the event that the disc 1 is not turned or that it is rolled under the keys 8 and 9 that are not allowed for any reason, the position of the workpieces relative to the tool is incorrect, the installation is turned off. The device of the proposed design allows to increase the reliability of work and accuracy of fixation in comparison with the known device. Claims of the invention: A revolving device for feeding piece blanks containing a transport disk mounted on a base with workpieces and grooves on its upper end, a disk turning mechanism and retainers fixed in the housing in the form of keys with bevels interacting with a disk, characterized in that in order to increase the reliability of work and accuracy of fixation, the keys are placed in the housing with the possibility of rotation around the axis installed in it and spring loaded, the housing is equipped with a spring-loaded bracket with a collar with one side us and the abutment on the other for holding one of the keys on the disk when it is unlocked and for releasing this key during rotation of the disc, with one set of keys to cooperate with its bevel stop bracket.
