Description

made in one piece with stops and meshing with the wheels of adjacent levers, single-arm levers 13, one end rigidly connected to shafts 4, and at the other end bearing rollers 14 entering the groove of the bar 15. The bar has a rod 16 installed with possibility of movement in the guide 17. The drive to return to the initial position is made in the form of a spring 18, which presses the bar 15 to

The invention relates to the mechanization and automation of sheet shtampovka processes and can be used for orienting rectangular sheet blanks before feeding them to machining presses, guillotine shears, sheet bending presses and the correct mashes.

The purpose of the invention is the expansion of technological capabilities by reducing

Claims (3)

1. DEVICE FOR ORIENTING RECTANGULAR SHEET Billets, comprising a support frame with guides, two carriages mounted in guides with the possibility of reciprocating movement, two stops mounted on each carriage with the possibility of interaction with the workpiece, and a drive for synchronous movement of carriages, characterized in that, in order to expand technological capabilities, each emphasis mounted on each carriage is made in the form of a pair of single-arm levers mounted with the possibility of rotation, each Ara of single-arm levers is kinematically connected with each other by a mechanism of synchronous rotation of the levers, while the mechanism of synchronous rotation of the levers is equipped with a drive to return the levers to their original position. 2. The device according to π. 1, characterized in that the mechanism for synchronous movement of the carriages is made in the form of an endless chain, the opposite branches of which are connected to the carriages of two pairs of gears that are meshed, and a four-link linkage mechanism, while each gear wheel is rigidly connected to each one-arm lever and mounted on the axes of rotation of the latter, and the output links of the rocker mechanism are rigidly mounted on one of the gears of each gear pair. 3. The device according to π. 1, characterized in that the drive return the levers to their original position is made in the form of a spring mounted with the possibility of interaction with one of the elements of the mechanism of synchronous rotation of the levers.
