SU1214295A1 - Automatic machine for coiling helical springs - Google Patents

Description

The invention relates to the processing of metals by pressure, in particular to automatic devices for the coil springs.

The aim of the invention is to increase the productivity of the machine and the quality of the springs produced.

FIG. 1 shows a spring coiling machine; in fig. 2 - made spring; in fig. 3 - working bodies of the machine at the time of winding the spring; FIG. 4 — Vic A, FIG. 3

In the case t of the machine, there is a worm drive consisting of a worm shaft 2 with two worm gears 3 and 4 and three worm wheels 5, 6 and 7, two of which are intended for rotation of the feed rollers 8 and 9, and the third results rotation of the caval stop 10. In the housing 1 there are wiring 11 and 12 for straightening the wire and directing it to the winding zone. A navibach stop 10 is mounted on a slide 13. In the caval stop 10, windows 1 are made, n the fixed 15 and stationary 16 cutting knives are located, the Halsday of the knives 15 is fixed in a spring-loaded holder 17 abutting on top3
