6 fm.1 The invention relates to the mechanization of production, namely, devices for feeding material into the treatment area, and can be used in the processing of long matter, such as flexible pipes. The purpose of the invention is to improve the accuracy of the supply of flexible material. FIG. 1 shows schematically the proposed device for the stepwise feeding of a lengthy material, the general view in FIG. 2 is the same, the plan view in FIG. .3 - section A-A in FIG. 1, in FIG. 4 shows a section BB in FIG. one; FIG. 5 is a view B of FIG. one. . The device for the step-by-step feeding of a lengthy material comprises a bed 1, in the racks of which a cam shaft 3 is installed on under the hips 2, which receives rotation from a drive (not shown). Straight wiring 4 is also mounted on the posts of the bed 1, consisting of two parts 5 and 6 interconnected with a gap, facing one surface of the other which are made with the guide groove 7. The device contains a long-distance material transfer mechanism. the form of two closed tapes 8 and 9, covering the rollers 10 and located one above the other, whose branches, facing one another, are placed in the guide grooves 7 parts of the wiring 4 arbor 11 and clamping slider on carriage 12 mounted for reciprocating movement along wiring 4. Each of carriages 11 and 12 contains movable 13 and stationary 14 working elements placed in the gap between parts of wiring 4 "Moving working movable mechanism These 13 carriages are cams 15 and 16 placed on the shaft 3. The movement mechanism of the movable carriage 12 is designed as a bevel gear 17 mounted on the shaft 3 and engaging with the gear 18 mounted on the shaft 19 in bearings 20. On w The end of the shaft 19 is fixed to the crank disk 21. To fasten the axis of the connecting rod 22, the disk 21 is made with a groove, along the edges of which divisions are applied, determining the size of the material feed pitch. The other end of the connecting rod is connected to the movable carriage 12. The tape B of the material transfer mechanism is double-layered with an outer layer 23 of elastic material, for example, foam rubber, and a V-shaped groove 24 is made on the outer surface of the tape 9 along its entire length. elements 13 of the carriages are connected with the corresponding cam by means of a spring-loaded lever 25, a movable support 26, a spring-loaded lever 27. Before wiring 4 an inlet pipe 28 is installed, and after it - an outlet pipe 29 having an aperture diameter the material and the transverse groove for the entry of the disk knife 30. Before the inlet tube 28 on the base 1 there is a drum. 31 for coil material to be processed. The disc knife 30 is mounted on the shaft of an electric motor 32 mounted on one end of a spring-loaded lever 33, the second end of which has a roller, covering the cam 34 of shaft 3. The rotation of the cam shaft 3 at a constant speed through the gears 17 and 18 and the shaft 19 is connected to the crank disk 21, and from it, through the connecting rod 22, the reciprocating movement of the movable clamping carriage 12 is transmitted. In the leftmost position, the movable working element 13 from the cam 15 is raised by the action of the levers 25 and 27, pressing the belt 8 and 9 to the stationary worker 14. The branches lementu belts are moved to the rightmost position, wherein said movable operation member 13 is lowered, releasing the belt and the movable clamping carriage 12 starts moving to the left. The movable operating element of the fixed clamping carriage 11 clamps the tapes, preventing them from moving backwards. The material being processed is a flexible tube, from the drum 31 through the inlet pipe 28 is introduced into the V-shaped groove 24 of the belt 9, is clamped in it by the outer layer 23 of elastic material and drawn along with it. After the end of the working stroke of the movable clamping carriage, the lever 33, under the action of the cam 34, lowers the rotating blade 30 into the transverse groove of the output pipe 29 and cuts off the material that is fed into the feed step. The use of the invention improves the accuracy of the supply of flexible material.
