Description

The proposed method of manufacturing flexible metal shafts is that a series of wires tightly pressed to each other, under controlled tension, is wound helically on a rotating core. To guide the wires, a clamp clamp is used, consisting of a plate with a groove closed by a lid with plates fixed to it on bolts.

In the attached drawing of FIG. 1 shows a longitudinal section of the device; FIG. 2 is a front view of it; FIG. 3 is a top view of the device with the cover removed; FIG. 4-top view of the cover.

The proposed fixture consists of a plate 1, in which there is a groove 6 for placing wound in it (wires to be wound. The width of the groove is determined by the number of wound wires and the depth by their diameter, the depth being made somewhat smaller than the diameter of the wire so that 2 it was possible to give the wires the necessary tension. The plate is closed by a lid 2 attached to it with the help of four screws 3.; by clamping these screws stronger or weaker, it is possible to give the wires passing through the groove proper tension. Two plates 4 are suspended from each, on two bolts 5, of which these two plates: one left or right takes part in the work, looking at the direction in which the shaft is wound.

To manufacture the shaft with the aid of the proposed fixture, one end of the rod is fastened in the lathe chuck, around which the wire should be wound; the other end, the rod, is passed through a stop located at a distance from the cartridge, defined by the length of the shaft to be rolled, the axis of the hole for the rod at the stop and the spindle axis being in one straight line. An emphasis is placed / equipped with a ball bearing tension bolt, with the help of which the rod is rotated. Before winding, the plates 4 are removed, and the cover 2 is pressed to the plate 1 so that it is possible to freely pass through the groove 6 the ends of the twisted wires fixed in any way to the cartridge. Then the plate 1 is pulled close to the rod, the cover 2 is slightly pressed to the plate 1 so that the wires exit the groove under some tension, and as the machine rotates slowly, winding spirals onto the rod from the cartridge to ynopy, v

, and immediately after that, separate turns of the spirals soften the raft. But: - near the other. When a necessary number of turns is required for a-j vito, it is sufficient that they can be given to cover 2 with plate 4, this plate is pressed {with two bolts to cover). Later, the machine works at a high speed, j and occurs automatically, j with it only necessary to uds-rzhizzt: all the adjustment from the gate, play together | with rod; the feed is adjusted; -1and I is produced by a spiral already wound, I which in this case is zag;: - :: it is a running zint of a turning machine.

When the first layer reaches the end of the manufacturing process, the plate is 4-wrung out and the device is set so that the new spirals lie on top of the wound, but in a different direction, and produce a name (on the second ;; on the first one in the same way, but already

clamping the coils with another plate 4. Thus, by winding the wire in several layers and spirals, a ball of the required diameter is made.

The subject matter of the invention.

1. A method of manufacturing flexible metal valos, characterized in that a series of wires tightly pressed to each other under a controlled tension is wound in a screw-like manner onto the inclining core by moving the wires along the core back and forth.

2. A device for the manufacture of flexible metal shafts according to the method described in paragraph 1, characterized by the use of a clamp clamp consisting of plates 1 sec. B, closed by a lid 2 with plates 4 fixed to the latter.
