Abstract

The invention relates to the cold treatment of metals by pressure and can be used to feed strip and strip material into the working area of a press. The aim of the invention is to expand the technological capabilities of the device by ensuring the supply of different material and adjusting the feed pitch in a wide range without stopping the drive shaft. The device contains a copier drive mechanism, the copier opens the fork and fixes the material. The mechanism is a synthesis of crank link and slider-slider mechanisms, the flow diagram of the feed operation, and hence the feed step, is controlled by the position of the swing axis of the two-arm (rocker arm). There is also a wedge clearance adjustment mechanism in the feed rollers depending on the thickness of the feed material. Adjustment of the feed step, as well as adjustment of the gap in the rolls, can be carried out remotely without stopping the press, which significantly reduces the time spent on re-equipment and also uses this feeder in a flexible automated sheet-forging industry. 1 il.

Description

The invention relates to the cold treatment of metals by pressure and can be used to feed strip and strip material into the working area of a press.

The purpose of the invention is the expansion of technological capabilities by feeding material of different thickness and adjusting the feed pitch in a wide range without stopping the drive shaft.

The required feed pitch is adjusted by displacing the yoke 28 with the help of the running air 30 from the electric motor 35 through the worm gear 31. The feed pitch is changed by shifting the average position of the copier bar 9 when it is

The drawing shows a device for Yu reciprocating movement of the feed strip and tape material roller 8, which leads to a measurement in the working area of the press.

The device includes a housing

Under the guides 10 there is a feed setting mechanism for a different material thickness, which consists of a movable wedge 18 and a fixed wedge 19, which is a wedge support, and screws 20 with springs 21. A movable wedge 18 is connected by a worm gear 22 and a lead screw 23.

The drive of the copying bar 9 g is shown), consists of a multi-link articulated lever mechanism: a crank 24 mounted on a press drive shaft, a connecting rod 25, bar 26 and a two-armed swing arm 27 pivotally installed in a cushion compression

When the roller descends from the ledge of the copier, the rolls are closed, gripping the material, and at the same time the material is released by the clamping jaws 11 and 12. The material is fed to the specified step. Then the cycle repeats.

The clamping force of the rolls is adjusted by the screw 17, and the force of the clamping
