Abstract

The invention relates to the cold working of metals by pressure and m. Used to supply long material to the treatment area. The goal is to increase the reliability of work. The device contains cams mounted on shafts, brake pads, springs, stepping stops. The latter are located at a distance from the vertical axis of the feeding rolls in the course of the feeding, which is one and a half of the feeding step, and from the center of the working zone at a distance that is a multiple of the feeding step. The strip is fed up to the stop fixed to the spring-loaded lever of the feed roller braking mechanism. The feed rolls, rotating, move the strip to the feed step in the treatment area. The working profiles of the feed rolls are formed by longitudinal depressions and protrusions. The lifting of the spring-loaded arms is carried out by cams mounted on drive shafts that do not feed the swaths. 3 il. (L

{joOjifiTeiine refers to the cold working of metals by pressure and can be used to feed long materials into the treatment area.

The goal and: acquisitions - increased reliability of work.

FIG. 1 shows a device for feeding a lengthy material to: a treatment area; in fig. 2 is a section L-A in FIG 1J in FIG. 3; is a section B-B in FIG. 2

The device contains two pairs of feed rolls 1 and 2 located on both sides of the press 3, the spindle 4, in which the shaft 5 is mounted, carrying the bevel gear 6 and the gear wheel 7. The roll 2 is mounted on the shaft 5 with 1; keyway 8, discs 9 and nuts 10, screwed on the shaft 5.

In case 4, sliders 11 are movably mounted, connected through elastic elements 12 to clamping force adjustment mechanism 13, complete. .1m in the form of screws, Shaft 11, shaft 14, brake disk 15 and gear wheel 16 are installed, the input is: gearing with gear wheel

On the shaft 14 is fixed feed roller 1 with the help of disks 17 and nuts

18, screwed onto the shaft 14; The working profiles of the swivel rolls 1 and 2 are formed by longitudinal hollows and protrusions,

In case 4, it is pivotally fixed at one end on the side of press 3 (treatment area) with the ability to interact with a brake disc 15 pbPiar

19. The other end of the lever 19 is spring-loaded to the body 4 (brake disk 17) by a spring 20. The lever 19 is set in motion around the lamp 21 and from the cam

22 mounted on the shaft 14. The gears 6 are connected via the shaft

23, a chain drive 24 with a drive shaft 25 of the press. On the lever 19 with one hundred RONES of the press 3 are fixed ynopi.i 26 with the possibility of interaction with the feed material 27, strip or tape. The stops 26 are positioned from the vertical axis of the rolls 1 and 2 at a distance equal to 1.5 of the feed step in the feed direction, and from the die 28 at a distance that is a multiple of the feed step.

The device works as follows.

Shaft 25 through chain drive 24, shaft 23 and 1 and gear 6 is driven throughout

Loading of the floor) C.1 expresses the map. With great difficulty at the speedframe, the roller conveyor (not shown) and then the roller conveyor feeds the roller feed, and the rolls can feed the material with a maximum of one step, and ds galken

10 BEFORE the stop is produced by a drive roller table, having a higher feed rate, I work from a separate drive. Further, the material is captured by the rolls 1 and 2 and fed

(5 per step, equal to the length of the arc formed by the contact of the upper and lower rolls. Transition to qilin ;; the oric surface of a smaller radius is accompanied by the formation of a chazor, which

20 allows the shaft to rotate freely while the material is stationary, which is held until a follow-through feed cycle in an unattached state by two brakes with adjustable clamping force.
