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. According to the main author. Ev, no. 889223, a device for feeding strip and tape material into the working area of the press, content housing, feed yalki mounted therein, at the ends of which are attached to the brake pads, which interact with the brake pads, which are fitted with the plane perpendicular to the axis of the sajHcoB podsaschih and fixed to the body with the possibility of adjusting parallel to the axis of the rolls, and the brake pads attached to the plate with the possibility of interaction with the side brake discs y. The disadvantages of the known device are low reliability of operation and difficulty of adjusting the braking force. The aim of the invention is to increase the reliability and improve the conditions for adjusting the force Tojwioate. This goal is achieved by the fact that the device for supplying strip and tape material, comprising a housing, mounted feed rolls on which ends brake discs are interconnected with brake pads, which are provided with a pin located in the plane perpendicular to the axis the feed rolls and mounted on the body with the possibility of reglaring movement parallel to the axis of the rolls, and the brake pads are fixed on the plate with the possibility of interacting with the side of the brake discs An additional plate, located perpendicular to the axis of the feed rolls and mounted on the housing with the possibility of adjusting movement parallel to the axles of the rollers, with additional brake pads mounted on the additional plate with the possibility of interaction with the other lateral side of the brake discs. FIG. 1 shows the proposed device, a general view; in fig. 2 is a section A-A in FIG. one; on; FIG. 3 is a section BB in FIG. one; at 10i of fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. 1. A device for feeding strip and tape material into the working area of the press includes a housing 1, in side racks 2 and 3 of which windows are made, where the supports 4-7 of the upper 8 and lower 9 feed rolls are mounted. On the supports 4 and 5 of the upper roll 8 are the adjusting screws 10, screwed into the rack 2 and 3, and on the supports 6 and 7 of the lower roll 9 - the pushers 11 and 12, respectively. The pusher 11 is driven in the vertical direction by the piston 13 of the power cylinder 14 mounted in the housing 1, and the pusher 12 is driven by the piston 15 of the power cylinder 16 mounted in the housing 1. The pushers 11 and 12 are mounted in sleeves 17 and 18. At the ends of the rolls 19 and 20, respectively, serrated coupling halves 21 and 22 are installed. On the casing 1, there are cadium columns 23, and at the ends of the rolls 19 and 20, respectively, brake discs 24 and 25. On the guide columns 23 a plate 26 is mounted, on which the friction plate 27 is attached, brake pad and inter The supporting plates 28 and nuts 29 are also installed on the side plates of the brake discs 25 and 24. On the guide columns there is also a support plate 28 and nuts 29. On the case 1 a screw 30 is fixed, passing through the plates 26-28 and bearing nuts 31. On the guide columns 23 and screw 30 Belleville springs 32 installed between plates 26 and 28 are installed. Position 33 denotes material. The device is equipped with additional spring springs 34, pads 35 mounted on an additional plate 36 mounted on the second sidewalls of brake discs 24 and 25 in the interval between housing 1 and brake discs. The device works as follows. After the supply of material 33 (strips or ribbons), the working medium is fed into the working cavities of the power cylinders 14 and 16. The pistons 13 and 15 through the pushers 11 and 12 respectively move the supports 6 and 7 upwards. The roller 20 with the roller 9 is also moved upwards, and the material 33 is clamped between the rollers 8 and 9, during the rotation of which the material 3

Rial 33 is moved to a press working area (not shown) in a feeding step. The breaking of inertial forces, when the rolls 8 and 9 stop, is due to the frictional forces between the brake discs 24 and 25 and the friction plates 27 and 35 (brake pads). Braking force, i.e. The pressing force of the friction plates 27 and 35 to the brake discs 24 and 25 is adjusted by nuts 31, which move the base plates 28 and 36, compressing prztainy 32. The latter move the plates 26 and 36 along guide columns -23.

The elimination of axial movements of the feed rolls 8 and 9 is achieved by installing additional springs 34, as well as brake pads 35 and plate 36 on the direction. columns 23 in the gap between body 1 and the second sides of the brake discs 24 and 25. fO

The use of the invention improves the reliability of the device in operation and improves the conditions for adjusting the braking forces 5.
