Abstract

The invention relates to electrical engineering and can be used for cutting electrical wires and other long objects. The purpose of the invention is to simplify the construction and increase the productivity by providing non-stop movement of the wire. A wire feeder is installed on the base 1 in the form of a chain 5 mounted on sprockets 3. At the links of the chain 5, working heads 6 with cutting or gripping elements are installed. On both sides of the chain 5, on the base 1, two cam loops 9 are secured. When the chain 5 moves to the cam zone 9, heads 6 with gripping elements clamp the wire and drag it along with the chain 5. When heads 6 fall into the cam zone 9 with cutting elements, the latter cut the wire. Installing the working heads on the moving chain ensures non-stop movement of the wire, increasing the device performance and simplifying its design. 2 hp f-ly, 5 ill. SO with

Description

FIG. one

The invention relates to electrical engineering and can be used for cutting electrical wires and other long objects.

A machine for cutting wires is known, comprising a base on which cutting elements are mounted, a powered wire feed device and gripping elements,

A disadvantage of the known automaton is its complicated structure due to the presence of numerous control and executive bodies, low productivity due to the intermittent operation cycle, as well as the limited length of the wires to be cut,

The purpose of the invention is to simplify the construction and increase the productivity by providing non-stop movement of the wire,

Fig, 1 shows the machine, a general view; in fig. 2 - working head with cutting elements; FIG. 3 is a view A of FIG. 2; in fig. 4 - working head with gripping elements; in fig. 5 is a view B in FIG. four,

Wire cutting machine contains the following main components and elements.

On base 1, there are guide rollers 2 and a wire feeder containing sprockets 3, engine A and chain 5 mounted on sprockets 3. At the links of chain 5, working heads 6 with cutting 7 or gripping 8 elements are installed (Fig. 2-5 ). Parallel to chain 5, on either side of it, on base 1 are placed two guide cams 9. Wire is fed from the drum. Each working head 6 contains pushers 10, guide elements on the rod 11, mounted on links of chain 5, springs 12, stops 13 the stroke of the pushers 10 and the rollers 14. The cutting 7 or gripping 8 elements are fixed at the ends of the pushers 10 facing each other, and are located on both sides of the chain 5.

The number of working heads 6 is such that when the chain 5 moves in the area of the guide cams 9, at least one head with gripping elements 8 always appears. The number of heads 6 with cutting elements 7 / is determined by the required length of the wire blanks. With one such golokok b, the length of the cut wires is equal to the length of the chain 5, with two or more lengths of the segments are equal to the distances between the adjacent blocks.

Pushers 10 working heads 6, placed on one side of the chain 5. can be rigidly fixed to the rods 11. In this case, the corresponding guide cam 9 is made in the form of a straight line bus.

The machine works as follows. The end of the wire is passed through a system of guide rollers 2 and is placed on chain 5 in the area of guide cams 9. Motor 4 is turned on, moving chain 5, Working head b with gripping elements 8 enters the section between cams 9.

0 The pushers 10, interacting with their rollers 14 with the cams 9 and overcoming the action of the springs 12, move along the rods 11 towards each other. The gripping elements 8 clamp the wire and carry it along with the chain.

When the head 6 with the cutting elements 7 enters the area of action of the cams 9, the latter cut the wire in the same way.

0 After the exit of the working heads of b from the zone

steering cams 9 and cutting 7, and

the gripping 8 elements under the action of the spring 12 are consumed by the spring and release the wire.

Adjustment to the required length of blanks

5 is accomplished by changing the length of the chain 5 or swapping the heads 6.

Installing the working heads on the moving chain ensures non-stop movement of the wire, increasing the efficiency of the device and simplifying its design.
