Abstract

The invention relates to the cold treatment of metals by pressure and can be used to feed strip and strip material into the treatment area. The purpose of the invention is to improve the reliability and accuracy of the feed step. The material, strip or ribbon is fed to the treatment zone with a lower drive feed roll and an upper pressure feed roll for the feed step. The stopping / braking / of the material during its processing is carried out by the clamping jaws when raising the upper pressure feed roll and lifting the material above the lower drive feed roll. The upper presser feed roll is lifted by pushers. The material is lifted by a puller made in the form of strips arranged parallel to the feed direction between the feed rollers. The braking / stopping / of the material is carried out by upper clamping jaws fixed in the housing and lower clamping jaws. The lower jaws are located below the feed plane, and the upper jaws are fixed above the feed plane. The plate, the pushers and the lower clamping jaws are fixed on the traverse in the vertical direction. The clamping jaws are arranged in pairs on either side of the feed rolls. 1 hp f-ly, 2 ill.

(54) DEVICE FOR SUBMITTING STRIP AND TAPE MATERIAL TO A TREATMENT AREA

(57) The invention relates to cold metal forming and can be used to feed strip and tape material into. treatment area. The purpose of the invention is to improve the reliability and accuracy of the feed step. The material, strip or ribbon is fed to the treatment zone with a lower drive feed roll and an upper pressure feed roll for the feed step. The stopping (braking) of the material during its processing is carried out by clamping and jaws when raising the upper pressure feed roll and raising the material above the lower drive feed roll. The upper presser feed roll is lifted by pushers. The material is lifted by a puller, made in the form of strips arranged parallel to the feed direction between the feed rollers. The material is braked (stopped) by upper clamping jaws fixed in the housing motionless and lower clamping jaws. Lower clamping jaws are located under the plane of feed, and the upper ones are fixed above the plane of feed. The plate, the pushers and the lower clamping jaws are fastened on the vertical traction drive in the vertical direction. The clamping jaws are arranged in pairs on either side of the rolls. 1 hp f-ly, 2 ill.

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

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

1 shows a device for feeding a strip and tape material into the treatment zone; FIG. 2 shows section A-A in FIG.

The device comprises a base I, on which case 2 is fixed. In case 2, with the aid of shaft 3, there is a lower drive “feed roller”

4, vertical grooves 5 are made in which the sliders 6 are spring-mounted, spring-loaded in the direction of the shaft 3, we are sewn 7. In the sliders 6 with Ij assisted by the axis 8, an upper pressing feed roller 9 is mounted; containing a power cylinder 10 with a piston 11 carrying a rod 12, a frame 13 is fixed to the stock, 10 ke 12, carrying the rack. 14 and 15. On racks 15 pushers 16 are mounted, and on racks 14 are fixed pullers made in the form of strips 17 located under the 15th plane of the material 18 supply (strips or tapes) and placed in annular grooves 19 made in. roll 4. The lower clamping jaws 20 are fastened on the uprights 14, and in the housing 20 2 there are the upper clamping jaws 21.

 . -

The strips 17 are fastened from the feed plane at a distance greater than the pusher stroke 16.25

The device works as follows.

The material 18 is fed to the treatment zone with rollers 4 and 9 per feed step. 30 Then turn on. Power tsipindr 10. Piston 11 through rod 12 moves frame 13 upwards. The pushers 16 act on the roller 9, brake it and move it up, compressing the spring 7. 35 Slats 17 remove material 18 from roller 4 and move it up. The clamping jaws 20 and 21 clamp the material 18, the material feed is stopped. After processing the material 18 in the processing zone 40, a signal is given to turn on the power cylinder 10, the piston 11 with the rod 12 and the frame 13 move downwards. The strips 17 lower the material 18 onto the roller 4, the clamping jaws d 20 and 21 release the material 18, thicken, roll 16 out of the interaction with the roller 9. The roller 9 under the action of the springs 7 moves together with

pushers 16 downward and presses material 18 against roll 4. Then the cycle repeats.
