(54) DEVICE FOR CUTTING PROFILE ROLLS

one

The invention relates to the blank production of machine-building plants, namely, devices for cutting rolled sections.

A device for cutting corrugated steel, for example pipes, is known, which comprises a base with a fixed knife holder mounted on it with a stub knife mounted in it, mounted in guide bases with the possibility of reciprocating movement in a horizontal plane in a direction perpendicular to the feed direction of the section being rolled, a movable knife holder with a sleeve knife installed in it, made with shaped surfaces, as well as a slide with a pusher mounted with the possibility of interaction with the specialized surfaces of the movable holder 1.

In this device, two pushers are used for the reciprocating movement of the movable blade holder, which complicates the design of the device, and in addition, the device is intended to cut only one standard size of rolled metal, as in the known construction

There is no provision for a change in the initial displacement of the movable knife holder, which serves to cut the rolled steel. ,

The purpose of the invention is to simplify the design and expand the range of rolled products.

This goal is achieved by the fact that in a device for cutting section rolled products, for example pipes, containing a base with a fixed knife holder mounted on it with a sleeve knife mounted in it, installed in the guide bases in a horizontal direction in a direction perpendicular to the feed direction of the section being cut, the movable knife holder with the sleeve knife installed in it, made with the profile surfaces, and also crawled with a pusher, which is equipped with a finger, installed with the ability to interact with the profil surfaces of the movable knife holder, and the movable knife holder is equipped with one of its profile surfaces installed in it with the possibility of contact with the finger

H FIG. I shows the device, General View; pas figs. 2 shows section A-A in FIG. 1. A device for cutting section rolled products includes a housing 1 in which a fixed knife-holder is placed. 2, the cutting sleeve is pressed into the latter 3. In the horizontal directions of their housing 1, a movable knife holder 5 with a cutting-sleeve knife pressed into it 6. Inside vte.lochnye knives 3 and 6. The knives-mandrels 7 and 8 are dimensioned. A cutting pipe 9 is cut between the sleeve knives 3 and 6 and the knives-mandrels 7 and 8. The ejector body 10 is rigidly attached to the movable knife holder 5, inside which the ejector is placed A fir-tree 11 and a spring 12. On the movable knife-holder 5 there is a profile groove 13 in which a finger 14 is mounted, rigidly fixed on the pusher 15, and the pusher 15 is rigidly fixed on the slide 16. The slide 16 is movably mounted on the columns 17 fixed on the housing 1. The adjusting screw 18 is wrapped in the movable knife holder 5, the end of which protrudes inside the profile (groove 13 by an amount equal to about half the wall thickness of the pipe being cut 9.

The proposed device works as follows.

The knife-mandrel 7 is installed inside the cut pipe 9 at its end. Eat with a knife-mandrel 7 pipe 9 is inserted into the sleeve knives 3 and 6 and moves the ejector 1 to the extreme left position (Fig. 2), compressing the spring 12. In this case, the end of the knife-mandrel 7 rests on the end of the knife Amendment 8 and remains in place. The ends of the mandrel blades 7 and 8 and the ends of the bush blades 3 and b are in the same plane. When pressing the pedal of the press, the slider 16 together with the pusher 5 and the finger 14 moves downward (Fig. 1). When the finger 14 touches the adjusting screw 18, the movable knife holder 5 together with the stub knife 6 moves first to the right (Fig. 1) by the amount of the protrusion of the end of the screw 18 inside the profile groove 13. The pipe is cut and then to the left by the value defined by the profile groove 13 , finally. cut pipe. At the end of the stroke, the spring 12, through the ejector 11, ejects the cut pipe billet g. In the course of the slide 16 upward, the moving holder 5 takes the initial position and the cycle repeats.

The device for cutting profiles has a simple design, and also allows cutting of material of various sizes due to the possibility of adjusting the size of the notch of the mats tube.
