SU88913A1 - Device for automatically inserting insulating washers onto an electrical conductor - Google Patents

Description

An improved device is proposed for automatically inserting insulating washers onto an electrical conductor by means of a slider moving reciprocating in a direction perpendicular to the direction of movement of the conductor.

Existing devices are designed to use pre-cut insulation shafts, which necessitates the use of a complex feeder that provides a certain orientation of the washer cut relative to the conductor.

The aim of the invention is to simplify the design of the feeder by allowing the cutters to be cut just before they are placed on the conductor.

This is achieved by the fact that the knife, which serves to cut the washers, is located in the immediate vicinity of the conductor and is driven back and forth along the latter synchronously with the movement of the slide, which slides the washer onto the conductor.

FIG. 1 shows a schematic front view of the device in fig. 2 and 3 are side views, respectively, at the two extreme positions of the knife and ram.

In the upper part of the four-sided bed / there is a hole 2, the diameter of which corresponds to the diameter of the conductor 3, on which washers 4 are mounted. Under the hole there is a knife 5, which moves reciprocatingly. In the handle 6 of the knife there is a recess 7 in which the protrusion 8 of the beam 8 enters. With the beam 9, a lever 10 is connected. The bars 9 and 12 fitted with springs abut against the beam 9 to the arm 10. The second arm of the lever 10 rests on the lateral protrusion 13 of the slide 14. This lateral protrusion 13 in turn rests on an eccentric 15 sitting on the shaft 16 on which the pulley 17 is mounted. On the side, in the frame / there is an arcuate channel 18, the end of which is directly under the knife. In the front side of the frame, under the knife, there is a cutout that serves as a guide for the slider 14.

The washers 4 mounted on the conductor enter through the channel 18 to the rounded upper part of the slide M, which is in its lowest position, corresponding to the diameter of the washer, as shown in FIG. 1 and 2. The up and down movement of the slider is carried out by an eccentric 15, which in turn is rotated by means of a pulley 17 and a shaft 16. With the movement of the slider 14, the return movement of the knife 5 is connected. When the slider 14 is overshoted, the lever arm 10 rises up, resting on the lateral protrusion 13 of the slide 14, as a result of which the beam 9, and with it the knife 5 move to the left. The washer, sitting on the slider 14, is pressed against the knife 5 as it moves upwards and, as it is lifted, is cut through by the knife moving to the left. The blade of the knife expands upwards. The end of the knife is beveled. The cut-out washer extends on the extended part of the blade of the knife 5 so that at the moment of contact of the washer with the conductor it is unhindered on the last one. The bevel of the knife 5 serves to limit the depth of the slit, which should not go beyond the inner hole of the washer. At the moment of complete insertion of the washer on the conductor, the slider 14 and the knife 5 are in the second extreme position, in which the eccentric 15 will take the highest position — as shown in FIG. 3. Rods // and 12, fitted with springs, rotate lever 10 in the opposite direction as the slide 14 moves down and maintain the beam 9 in engagement with the handle 6 of the knife 5. As soon as the slide 14 lowers into its lower position, J8 drops onto it the next puck enters and the packing operation is repeated in the sequence described.

In case it is necessary to cut the washers not radially, but at an angle, the knife 5 is set at an angle to the axis of the washers.

Subject invention

A device for automatically inserting insulating washers onto an electrical conductor by means of a slider moving reciprocatingly in a direction perpendicular to the direction of movement of the conductor, provided with a knife for cutting insulating washers from the periphery to the central opening, characterized in that, in order to cut the washers directly before placing them on the conductor, the said knife is located in the immediate vicinity of the conductor and is driven back and forth along the latter with nhronno with slide movement.
