SU182099A1 - AUTOMATIC MACHINE FOR THE MANUFACTURE OF SPRING WIRES - Google Patents

Description

mostly auth. St. No. 128841 describes an automatic machine for making springs from a wire, comprising a rotating mandrel with a conical end, reciprocating, and a carriage with its feed mechanism ija located, reciprocating from the copier.

The described machine has improved performance and a simplified design, for which it is provided with a mandrel rotating in the pinch and a feed mechanism placed on the carriage performing reciprocating under the action of forces generated during wire winding along the guides placed between the mandrels, and the mandrels are installed in parallel between themselves and directed towards each other.

The automat is intended for the manufacture of gland springs and filters having tapered ends.

FIG. 1 shows a structural diagram of the described automaton, side view; in fig. 2 - head of the machine, side view, longitudinal section; in fig. 3 - the same head, top view.

which has an electric motor 2, which spins 5, mounted in rotation through shaft 3 and sleeves 4, mounted in two parallelly aligned heads 6. The mandrels 8, whose dimensions depend on the parameters of coil springs, are screwed into the spindle x using collet clamps 7. From the riots 9 fixed on the machine bed of the riots 9, the wire 10 passed through the mechanisms

feed 1, falls under the special grippers 12 rotating with the mandrels 8. The feed mechanisms // can, together with the common carriage 13, freely move along the guides 14 parallel to the axis of the mandrels under

the impact of forces arising from winding wire.

In the spindle heads 6 screw mechanisms 15 are mounted, which at the moment

the ends of the spring coiling move the sleeves 16 with the collet clamps 7 and mandrels 8 secured in their manner and inside the heads, with the result that the finished springs are removed from the mandrels and fall into the receiving hoppers 17.

The initial position of the feed mechanisms // relative to the heads 6 depends on the length of the springs being wound. This allows winding of springs of the same length or of two types of springs of different lengths.

When approaching the feed mechanism // close to the grip 12 on the mandrel 8, the spring winding begins. In this case, a force occurs, under the action of which the carriage 13 moves along the axis of the mandrel. After reaching the tapered end of the mandrel, the wire is twisted and cut. At this point, the second feed mechanism approaches the pick-up device of its head, and the second spring begins to wind on the second mandrel.

During the time of winding one spring using a screw mechanism 15 is removed from the mandrel of the second spring.

Subject invention

Automatic machine for the manufacture of wire springs according to ed. St. No. 128841, characterized in that, in order to increase productivity and simplify the design, it is provided with a mandrel rotating in a pinch and a feed mechanism placed on a carriage reciprocating under the action of forces generated during wire winding along guide rails placed between mandrels, and mandrels are installed in parallel with each other and directed towards each other.
