Description

(54) DEVICE FOR CUTTING WIRES

one

The invention relates to the processing of metals by pressure and can be used to cut wires to lengths.

There is a device for cutting wire that contains a coil holder, a wire feed mechanism in the form of two rolls, one of which is driven, a cutting mechanism made in the form of a rotating rotating disk, on which at least one knife is attached, which interacts with a fixed knife, fixed on a rigid support, the guide for the wire and the drive of the wire feed and cutting mechanisms, in the form of an electric motor 1.

The disadvantage of the device is the complexity of its design.

The purpose of the invention is to simplify the design of the device.

This goal is achieved by the fact that, in a device for cutting the wire containing the holder, there is a wire feeding mechanism in the form of two rolls, one of which is driven, a cutting mechanism made in the form of a rotating rotating disk on which at least one knife is fixed, interacting with a fixed knife mounted on a rigid support, wire guide and drive of the electric motor feeding and cutting mechanisms, driving rotating disk of the cutting mechanism and feeding roller of the feeding mechanism mounted directly on the shaft, at the electric motor. FIG. 1 shows the device, a general view; FIG. 2 is a section A-A in FIG. I; in fig. 3 is a view B in FIG. one; in fig. 4 - schematic diagram of the cutting process.

The device for cutting the wire contains the coil holder 1, the wire feed mechanism, made in the form of two rolls 2 and 3, the cutting mechanism, made in the form of a rotating disk 4, on which at least one knife 5 is attached, which interacts with a fixed knife

5 to 6 fixed to a rigid support 7, a guide 8 for the wire and a drive in the form of an electric motor 9. The roller 2 and the disk 4 with the knife 5 are mounted directly on the shaft 10 of the electric motor 9. The rolls 2 and 3 have a corrugated surface. Wire guide 8 is made in the form of a curved slotted groove and is located at an angle to the plane of rotation of the knife 5.

The entire device is mounted on base 11.

The device works as follows.

Wire; sa 12 from coil holder 1 through guide 8 enters the wire feed mechanism.

In the wire feeder, the nip roll 3 is pressed by the wire, which allows it to be fed to the cutter by the drive roll 2. The wire is cut by using at least one blade 5 mounted on the rotating disk 4 and fixed on the rigid support 7 of the fixed knife 6. The cutting edge of the fixed 6 can be located parallel or at an angle with respect to the axis of rotation of the disk 4. The edges of the movable knife 5 and the fixed 6 at the time of cutting the wire 12 parallel us to each other.

The proposed device has a simplified design.
