Description

The invention relates to the processing of metals by pressure, in particular to equipment for cutting wires, cables, cables and wires to lengths.

The purpose of the invention is to increase productivity and simplify the design of the device.

Figure 1 schematically shows the proposed device; figure 2 - section aa in figure 1; on fig.Z - view B in figure 2; figure 4 - diamond-shaped rod section.

A device for measuring cutting of lengthy material contains a giving mechanism 1, a mechanism for measuring length with measuring

roller 2, material feed mechanism in the form of thin rollers 3 with drive 4, material cutting mechanism including fixed 5 and movable 6 sleeve knives and movable knife drive in the form of a power cylinder 7 with support 8 fixed on its stem interacting with limit switches 9, and guide dies 10.

A receptacle of material pieces mounted on the housing 11 comprises a rotary disk 12 with uniformly fixed circumferentially rods 13 of rhombic section, and the distance between the rods

It is somewhat larger than the diameter of the material 14, thereby creating conditions for the passage of the material and its accumulation within the space bounded by the rods during the operation of the feed mechanism.

The rotation of the rotary disk 12 during the winding of the material 14 is carried out using a belt drive 15 from the drive drive shaft 4, due to the discrepancy between the linear speeds of the pull roller 3 and the turntable 12, the torque is transmitted from the pulley mounted on the hub of the turntable is produced by frictional force by interacting a spring-loaded friction disk 17 fixed on the pulley 16 with the end surface of the rotary disk 12, and the force of the spring 18 is adjusted by the nut 19.

To fix the rotary disk in the cutting position and accumulate material, the receiver of material pieces contains a wedge 20 fixed on the rod of the power cylinder 21, while fixing is performed by interacting the wedge with locking sockets made on the peripheral surface of the disk. There is also a reel of coils of material from rods of the rotary disk, which consists of a power cylinder 22, with a rod 23 of a disk 24 with holes for accommodating rods 13 in them, while the rod 23 moves in a guide sleeve 25, on the outer surface of which supports 26 are mounted rolling for rotating the rotary disk, and the disk 24 with the rod 23 is connected through the support 27 rolling.

The device works as follows.

After installing the coil with the material on the delivery device 1, the material is manually passed through the length measuring mechanism with the measuring roller 2, loaded into the grooves of the pulling rolls 3 of the mechanism and further through the guide die 10 the material is passed into the holes of the fixed 5 and movable 6 blades. Then, the drive of the pulling mechanism is turned on and the device operates in automatic mode.

The material, the exit from the holes of the fixed and movable knives through the guide die plate 10 under the action of the pull-on rollers 3, passes between the rods 13 and accumulates inside the space bounded by the rods, while the rotary disk is fixed from the rotation by a wedge 20, and the friction disk 17, associated with a belt drive 15 with a drive of 4 tons of the lower rolls 3, rotates with a slide relative to the end surface of the rotary disk 12. The amount of material stock accumulation is set on a time relay (not shown).

After stocking up the material,

sufficient for winding the first 1.5-2 turns, the time relay issues a signal for unscrewing the rotary disk, while the wedge 20 is removed by the power cylinder 21 from the locking nest of the rotary disk. The rotary disk 12 rotates, and the accumulated material with sliding relative to the rods 13 will go out of the space bounded by the rods, since the friction force between the material and the rods is insufficient to hold and grip the material.

After the rotary disk makes 1.5-2 turns, there will be 1.5-2 turns of material on the outer surface of the rods.

however, the adhesion force between the material and the rods will be sufficient for further winding to occur without slip.

Circumfeeding rod speed 13 more

linear speeds of pull rolls 3. which is necessary to eliminate the loop formed between the die 10 and the rotary disk when winding the first turns.

The measuring roller 2 for each revolution produces a pulse entering the pulse counter, which, after passing a given length of material, turns off the drive 4 of the material feed mechanism, turns on the fixation ram 21

rotary disk and power cylinder 7 drive movable knife 6, which produces cutting material.

At the end of the knife stroke, stop 8, acting on the limit switch 9, gives a signal to

moving the piston 23 of the power cylinder 22, while the disk 24. mounted on the rod, produces the removal of the coils of material from the rods of the rotary disk. The rod returns to its original position by a spring.

The signal for the filing of the next piece of material drive 4 feed mechanism receives from the limit switch 9, which is affected by the stop 8 when returning the rod of the power cylinder 7 to its original position. Then the cycle repeats.

As a result of using the proposed device in comparison with the known
