Description

10 15 20 25 30 35 456 657 safe control of the wire rod is in the area of the knife the heads.

According to the invention, the task is solved by a rotating wire cutter moves at high speed moving wire, which through a pivot tube, which engages a guide caliber for performing cutting the process is moved laterally between an upper knife and a lower knife, which are attached to flying, rotatably mounted knife heads, as well as that all incoming snout tips, rolling veins and final snout ends are led into a rear outlet part with from each other different scrap and rolled carcass channels, which wire scissors are distinguished in that the pivot tube consists of a funnel-shaped inlet, cylindrical pipe piece, a conductor piece tapered in the inner diameter and at the height of the cylindrical contour of the knife heads corresponding to the parallel lella guide walls and on the wire exit side a conical, shortly before the exit part closing nozzle.

A further feature of the invention lies in the fact that a saving for the cylindrical shape of the knife heads is slightly wider than the width of the upper and lower knives.

Exemplary embodiment The invention is described in more detail with a possible embodiment in connection with the accompanying drawings where: Fig. 1 shows a horizontal projection of the wire shears, Fig. 2 shows sections through swivel tubes, knife heads and outlet part and Fig. 3 finally shows a horizontal projection of Fig. 2.

Fig. 1 shows the active parts involved in the cutting process.

On the rolling goods entry side, it is at pivot point 1 on the substructure the bearing 2 is movably mounted and through the pneumatic cylinder 3 is movable pivot tube 4 arranged. the upper knife head 5 and the lower knife head 6 consists partly of the cylinder part 7 and partly of the one with threaded grooves 9 with equal pitch direction provided the conductor part 8. The knives is located in the cylinder part 7. The knife heads are releasably attached on knife shafts, which are mounted in the knife housing 10 in a flying manner. After the knife heads there is an outlet part 11 with the connecting scrap 10 15 20 25 30 35 456 657 'å path 12 to the disintegrator and roller seed path 13 to the drive device and caller.

The pivot tube 4 is recessed in the area of action of the knife heads and consists of the funnel-shaped inlet 14. the cylindrical tube paragraph 15. the conductor 16 tapering in the inner diameter. the parallel guide walls 17 and on the wire outlet side it conical nozzle 18. In the area of the guide walls 17 is limited the space for the roller seed 22 downwards and upwards through the cylindrical ones the surfaces of the knife heads. In the upper knife head 5 resp. lower knife the head 6 is the upper knife 19 resp. the lower knife 20. On the outlet side of the rolling stock is the outlet part with it in the middle stored and pivotable on both sides. pointed angularly designed the deflector 21 arranged.

The snip insert is carried out as follows: Coming from the wire rolling mill's water cooling section runs the vein 22 ended up in the pivot tube 4. According to Fig. 1 the swivel tube 4 past the snout knives on the side of them and the change moves through the scrap channel 23 in the outlet part 11 into the scrap path 12 and thus to the disintegrator. From a rolling stock kator in the area of the wire roll block furthermore an impulse for shear release of the continuous change and via the control with an adjustable time factor for preselecting the cutting length to a, pneumatic road valve. After actuation of this road valve on the oblique pneumatic cylinder 3 appears. This cylinder 3 engages a lever sleeve 25 enclosing the pivot tube 4 and touches both the pivot tube 4. guided by the ball cube 27 horizontally in the direction of the knife housing 10 as well as for the the bar sleeve 25 rigidly arranges the finger 26 vertically upwards inwards in one of the threaded grooves 9 on the conductor part 8. Through the fixed distance between the pivot tube 4 and the finger 26 as well as the upper and lower the distance of the knives 19 and 20 to the gangway division is ensured. les. that the knives during the cutting process are guided exactly between the the walls 17 and the cutting roller vein 22. While the snout tip runs through the scrap channel 23 in the outlet part 11 stands the deflector 21 tip in front of the plane of the knives towards the operating side. After 10 456 657 the snatching moves the beginning of the goods vein at the deflector 21 on the knife side past into the carotid canal 24 on the outlet part 11 in direction of the carotid artery section 13. During the time of the straight the passage of the carotid artery swings the deflector 21 slightly. so that its tip with respect to the knife plane will lie on the knife side. After that, the cutting impulse from the roll seed end is loosely opposite effect on the road valve. presses pneumatic the cylinder 3 the pivot tube 4 towards the operating side and the finger 26 falls into one of the threaded grooves 9 on the lower knife head 6. The roller the vein comes again between the upper and lower knives 19 and 20. the end snout end is separated and comes via the scrap channel 23 to the shot deflection.

Claims (2)

10 15 456 657 Patent claims 1. Rotary wire shears move at a high speed moving wire, which through a pivot tube. which engages in a guide caliber for carrying out the cutting process is moved laterally between an upper knife and a lower knife. which are attached to flying, rotatably mounted knuckle heads. as well as all incoming snout tips. roll goods veins and end nipple ends are led into a rear outlet part with mutually separated scrap and roll goods vein channels, characterized in that the pivot tube (4) consists of a funnel-shaped inlet (14), cylindrical pipe piece (15), one in the inner diameter of the joint - piece (16), and 1 height with the cylindrical contour of the knife heads (5, Ä) corresponding to parallel guide walls (17) and on the thread exit side a conical nozzle (18) closing shortly before the exit part (11). 2. Wire shears according to claim 1, characterized in that a recess for the cylindrical shape of the knife heads is insignificantly wider than the width of the upper and lower knuckles (19, 20).
