(54) DEVICE FOR MEASURING CUTTING WIRES

I

The invention relates to the processing of metals by pressure, in particular to devices for cutting wires, such as wires.

A device for measuring wire cutting is known, comprising a rotor housed in a housing with mounted on it with the possibility of radial adjustment movement with the jaw clamping and cutting mechanisms equally spaced around its circumference, a copier made in the form of a sector installed with the possibility of interaction with the clamping and cutting mechanisms, a removable collector connected to the rotor shaft, and a mechanism for performing a periodic cut 1.

However, the known device is unreliable in operation, due to the complexity of its design, in particular, the mechanism for carrying out a periodic cut.

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

The goal is achieved by the fact that the device contains a rotor placed in the housing with mounted on it with the possibility of radial adjustment movement and equidistant along its circumference

jaw clamping and cutting mechanisms, a copier made in the form of a sector mounted with the possibility of interaction with the clamping and cutting mechanisms, a removable collection connected to the rotor shaft, and a periodic cutting mechanism equipped with additional clamping jaws installed parallel to the jaws of the clamping and cutting mechanisms, and the mechanism for making a periodic cut is made in the form of a set with the possibility of reciprocating movement towards the additional clamping jaws and jaws a clamp and cut schtangi a guide for cut wire. FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; on

15 of FIG. 3 - clamping and cutting mechanism; in fig. 4 the same, side view, cut; in fig. 5 is a view B in FIG. 3

The device contains a rotor 1, in the radial grooves of which the clamping and cutting mechanisms 2 are installed with the possibility of movement using screws 3 built into the rotor 1. The matching ends of screws 3 are interconnected by bevel gears 4. The direction of the screw cutting of any two adjacent screws 3 - different . Parallel to the plane of rotation of the rotor 1, a fixedly flat copier 5 is installed, the working surface of which has a sector shape whose apex coincides with the center of the rotor, and the angle makes the wire intercept by the clips of two adjacent clamping and cutting mechanisms 2. Each clamping and cutting mechanism 2 comprises a movable knife 6 mounted on a carriage 7 movably mounted on vertical guides 8, made integral with the slider 9, and a fixed knife 10 fixed on the guides 8.

At the other end, a roller 11 with an axis 12, spring-loaded springs 13, directly interacting with the copier 5, is mounted on the carriage 7. The carriage 7 is attached to the carriage 7 by clamping screws 14 with springs 15 and a clamp 16, also sitting movably in the guides 8 and forming together with fixed knife 10 two parallel clamping jaws in the form of parallel grooves; clamping jaws 17 located on the side of the movable knife 6 and acting in the center, and clamping jaws 18 located further from the movable knife 6 and acting along the edges of the mechanism 2 of the clamp and cut.

To direct the wire into the grooves of the clamping jaws 17 or 18 parallel to the axis of rotation of the rotor 1, a shank 20 is seated in the sleeve of the housing 19, equipped with a guide roller 21 at one end, and connected with an actuating mechanism 22 at the other end. device 23 connected directly to the rotor shaft 1.

Removable collector 24 is mounted on a lifting mechanism disk 25, comprising a slider 26 and a rack and pinion gear 27, a slotted connection between the shaft 28 of the disk 25 and the drive shaft 29. The disk of the disk 25 and the shaft of the rotor 1 are provided with cams of the cam clutch. The wire to be cut is indicated by 30.

The device works as follows.

When the rotor 1 rotates, the wire 30 is constantly wound on the outer rounded sides of the clamping and cutting mechanisms 2, while entering the groove of the clamping jaws 17 or 18. Under the influence of the copier 5, the clamping jaws 17 and 18 converge to wire (cable) 30. The cut of the wire (cable) 30 occurs simultaneously or with some delay in the groove of the clamping jaws 17. Up to the groove of the clamping jaws 18, the movable knife 6 does not run. Each mechanism 2 clamps and cuts t there is no wire until it comes into action with copier 5 following in the course of rotation. The rod 20 with the help of the actuator 22 and through the counting device 23 periodically transfers the wire from the action plane of the clamping jaws 18 into the action plane of the clamping jaws 17. Control of the device is provided by setting the counting device 23 to a predetermined number of revolutions and also by adjusting on the necessary length of a cut, coming one turn. This is accomplished by rotating one of the screws 3, while the clamping and cutting mechanisms 2 simultaneously move along the guide slots of the distance names between themselves. The cut wire 30 under the action of centrifugal forces and weight enters the collector 24 and is laid there in the form of coils, and after filling it is replaced empty when the disc 25 is lowered.

The proposed device has a simple design, which makes it possible to increase the reliability of its operation.
