Description

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

one

The invention relates to cold working metap-pressure and can be used to feed strip and tape material in the treatment area.

A device is known for supplying a strip and tape material to a treatment zone, which has a lever mounted on the top plate with an axis, rotatable in a vertical plane, which enters holes in the material stuck in the material and interconnects with a bevel made on a matrix mounted on the bottom plate .

The lever is spring loaded in the opposite direction to the feed of material 1., 5

However, such a device can be used to supply a limited number of parts and it does not provide for the possibility of adjusting the feed rod.

Closest to the proposed in-20 is a device for feeding strip and tape material into the treatment area, which contains clamps located on both sides of the treatment area, alternately pressing the feed material to the fixed part of the device, and a die-cutter mounted on the fixed part of the device.

In the puller, a groove is made for the passage and for the formation of a loop thereof necessary for moving the material into the feeding step 2.

However, in the known device, the design of the material looping unit does not provide the possibility of adjusting the feed band.

The aim of the invention is to make it possible to adjust the material feed pitch.

Claims (1)

The delivered chain is achieved by the fact that in the device for feeding the strip and tape material into the treatment zone, containing at least two clamps, one behind the other in the feed direction of the material, forming a loop of material with a length equal to the material feed band; clamps and connected to 395 a vertically movable part of the device, the knots of looping are made in the form of a lever hinged by the other end on the fixed part of the device with the possibility of a gate in the ve the vertical plane, which interacts with the other end with the material, and the pusher mounted on the moving part of the device with the possibility of adjusting the movement in the horizontal direction and interacting with the lever. The lever is spring loaded relative to the movable part of the device. FIG. 1 shows schematically an apparatus for feeding a strip and foam material into a treatment zone, a section; in fig. 2 shows section A-A in FIG. 1. The device for feeding the strip and tape material into the treatment zone contains the lower plate 1, on which, by means of axis 2, a lever 3 is fixed at one end, the other end of which is connected by a spring 4 to the upper plate 5. Screw 6 is movably mounted on the top plate 5 bearing clamp 7, spring-loaded with respect to the top pin 5 with spring 8, screw in screw 9 with lock nut 1O and washer 11. In bottom part 1. the clamp 12 is installed, and spring 13 is placed between clamp 12 and washer 11. Clamp 12 rests on the ends of two levers 14 installed with the help of axles 15 In the lower ppite 1. In the upper plate 5 there are installed adjustable stops, made in the form of screws 16, interacting with the free ends of the double-arm levers 14. The position 17 designates the strip material or ribbon. .. On the top plate 5, the slider 18 is mounted with the possibility of horizontally moving the slider 18, carrying a screw 19, screwed into the upper plate 5 and carrying a locknut 20. On the slider 18, the plunger is fixed in the form of a roller 21 interacting with the lever 3. The lower leg 18 moves along horizontal guides 22 fixed to the top plate 5 or made integral with it. The lower columns 1 are fixed to the directing columns 23 with springs 24. The upper plate 5 is mounted on the guide columns 23. The upper plate 5 is driven by the guide columns 23 from the upper arm 25. The device for feeding the strip and tape material into the treatment area works in the following way. The double-shouldered lever 25 moves the upper plate 5 along guide columns 23 downward, compressing the spring 24. The clamp 7 presses the material 17 to the lower plate 1 screws 16 interact with the double-shouldered levers 14. The double-shouldered levers 14 rotate around the axes 15 and move the clamp 12 upwards. ROLLER 21 acts on the lever 3 and turns it around the axis 2, stretching the spring 4. The lever 3 acts on the material 17, moves it down into the notch in the bottom plate 1 and forms a loop of material 17. When the upper plate 5 moves along the guide columns 23 upward under the action of prundan 24, the clamp 7 releases the material 17, the screws 16 come out of engagement with the double-arm levers 14. The clamp 12 under the action of the spring 13 moves down and presses the material 17 to the bottom plate 1. The loop of the material 17 is selected by moving the material 17 to the left, for example, with material 17 is wound on a spool (not shown). Then the cycle is repeated. The effect of the use of the invention is to make it possible to adjust the material feed pitch. Formula of the invention 1. Device for supplying strip and tape material to the treatment area, containing at least two clamps, located one after the other in the direction of material supply, the node forming: no loops of material with a length equal to the step of material supply, located between the clamps and connected with a vertically movable part of the device, characterized in that, in order to adjust the feed pitch, the looping unit is made in the form of a lever hinged at one end on the fixed part of the device Twa pivotable in a vertical plane and other interacting
