Abstract

The invention relates to the processing of metals by pressure and can be used for cutting articles such as spirals. The purpose of the invention is to expand the technological capabilities of the device for cutting products. The auger spiral is threaded into the mechanism of the segments 13 between the guide rollers 14. The auger spiral moves around the axis of the shaft 4, the axis of which coincides with the axis of the auger spiral. When the auger helix presses on the axis and retracts the spring loaded straps, the tab leaves the contactless track switch, and the cut-off mechanism 13 starts cutting the helix. At the end of the cutting, the cut-off mechanism 13, the slip guide rollers 4, spirally 5, takes up its original position by means of the spring 7 and under the action of its own weight. 3 hp f-lyd 3 ill.

The invention relates to the processing of metals by pressure and can be used for cutting articles such as spirals of the screw,

The aim of the invention is to expand the technological capabilities of a device for cutting articles such as spirals of an auger.

FIG. I shows a device for cutting articles such as screw spirals; general view; FIG. 2 is a view A-A in FIG. on fig.Z - section bb in figure 2.

A device for cutting articles such as spirals of a screw contains a frame 1 with tubes 2 with bushings 3 fixed on it. On frame 1 there is a shaft 4 with sockets 5 and openings.6, A spring 7 is mounted on the shaft 4, bounded on one side by a bracket 8 with an installed there is a limit switch 9 on it and a lock washer 10 on the other side. The spring 7 interacts through the ring 11 with the sleeve 12 bounded by a second support washer 10. On the sleeve 12 there are fastenings of the mechanism 13, which has guide rollers .14. A sensor 15 is installed on the shaft 4, consisting of a housing 16 on which a rotatable sleeve 17, limited by screws 18, wedging cams 19, interacting with a nut 20 and fixing the sleeve 17, a plate 21 and a pointer 22, are mounted on the hub 17; spring-loaded springs 24. The slats 23 are interconnected by an axis 25 and a petal 26 is mounted on one of them. A non-contact limit switch 27 and a spring-loaded clamp 28 are fixed to the housing 16, the pressure roller 29 and the driving roller 30 are mounted on the frame 1, which is driven in motion driven 31,

The device for cutting products works as follows

S

Depending on the direction of the screw wrench. The mechanism 13 is turned on the sleeve 12 to the desired position and secured with a locking screw. The spiral of the screw obtained from the strip coil in the rolling mill is filled into the mechanism 13 between the guide rollers 14, which the auger spirals after the segments are not allowed to enter the segments mechanism. The screw auger moves around shaft 4,

2

the axis of which coincides with the axis of the spiral auger, and pipe 2 with sleeves 3,,. mounted on frame 1 limits it from shifting,

The sensor 15, depending on the screw twist of the screw, is installed in the desired position and fixed with a spring-loaded clamp 28 mounted on the housing 16 through the holes 6 on the shaft 4. To fit the sensor 15 on the shaft 4 more accurately, unscrew the nut 20 and the wedge terminal cams 19, freeing the sleeve 17, limited by screws 18,

not allowing it to move beyond the wedging (cams. Then, turning the sleeve 17, align the pointer 22 with the divisions on the plate 21, which is calibrated depending on the inner diameter of the screw helix, as well as on the direction of winding and the number of turns, on the axis 25 and will lead spring-loaded springs 24

strap 23, the petal 26 comes out of the contactless end of the switch 27 and the mechanism 13 segments will begin a segment of a spiral. During the cutting time, the mechanism 1 3 segments on the sleeve 12, following the helix, will rotate 90 ° and move forward forward, compressing the spring 7, which is installed between the ring 11 and the bracket 8. In an emergency situation, if the mechanism of the segments is wedged during the helix cut, through the ring 11, the compression force is transmitted to the limit switch 9 and the drive of the rolling mill stops, the Crushite 8 is stopped by a lock washer 10 installed in the socket 5,

After cutting, the cut-off mechanism 13 slides spirally with the guide rollers 14 in its initial position with the help of the spring 7 and under the action of its own weight,

Depending on the number of turns, the mechanism 3 is placed on the shaft 4 between the sockets 5 and limited on one side by the locking washer 10, and the other by the ring 11, the spring 7, the bracket 8 and the second locking washer 10,

After the lengths, the helix is pressed by the gland roller 29 to the drive roller 30, the drive 31 is turned on and the workpiece is removed to the container.
