Definitions

  • the invention relates to a machine for winding springs with a driver for the spring wire end, a mandrel and a feed drive, wherein the mandrel can be clamped between two carriages which can be moved relative to one another but together during the winding feed.
  • Spring winding machines which work program-controlled, are known in various designs, such as from DE-PS 29 24 603, DE-AS 17 52 891, DE-OS 35 39 730 and DE-GM 19 93 530. It is from these Writings not recognizable, however, that these known winding machines can also control springs with wire diameters up to 30 mm cold and up to 50 mm warm, although DE-GM 19 93 530 mentions the winding of a possibly heated rod. Furthermore, these known winding machines are apparently those in which the winding device is arranged above the machine bed, so that the wound springs cut from the rod or wire can fall into the machine bed.
  • the invention has for its object to provide a program-controlled, rationally working spring winding machine of the type mentioned, in which the finished springs can easily be collected in a predetermined number.
  • the spring winding machine not only enables the fully automatic, electronically controllable production of helical compression springs, coil tension springs, leg springs and similar springs, the number of which can also be specified, but also springs with a wire diameter of up to 30 mm cold and up to 50 mm warm are wound, and the finished springs can advantageously be collected in a container below the machine, because all the devices for winding the springs are guided laterally on the machine bed.
  • a machine bed (1) is attached to the side of a machine frame (2) and forms a sliding guide for two slides (3) and (4), which can be moved relative to each other via mandrel pull cylinders (5), but when a spring is wound together according to the spring winding path by a spindle (not shown) located in the machine bed (1) can be moved.
  • the drive motor for the spindle is indicated at (6).
  • a long mandrel (7) is rotatably attached at one end in the carriage (4) and is centered by a cone (8) at the other end in a driver (9) which is rotated on the carriage (3) by a drive (10) in order to wind the end of a wire feed (11) with simultaneous advance of the slides (3, 4) around the mandrel (7) until the preselected number of turns of a spring is wound.
  • the mandrel (7) inevitably rotates. It can be supported by two lower support bezels (12) and an upper support bezel (13), which can be adjusted according to the diameter of the mandrel (7).
  • the upper support bezel (13) is generally not used for right-handed springs; it may be used with left-handed springs.
  • the driver (9) rotates back a little so that the spring is relaxed and loses its frictional engagement with the mandrel (7).
  • the slides (3, 4) are moved apart by program-controlled actuation of the mandrel pulling cylinders (5), so that the mandrel (7) is pulled out of the spring, which then sits on the wire feeder (11) in the insertion rollers (14).
  • These are on a support-like adjustment device (15) on the machine frame (2) in height and perpendicular to the axis of the Dorns (7) adjustable.
  • the insertion rollers (14) are pivotally mounted about a vertical axis so that they can adjust to the pitch of the spring turns. In this position, they can then be determined by an actuating cylinder (16).
  • a pair of scissors (17) (see FIG. 2) is pivotably mounted on the adjusting device (15). These scissors (17) are pivoted towards the wound spring or the wire feed (11) and cut the spring off the wire feed (11). The finished spring can then fall into a container (not shown) under the machine, since the machine bed (1) is arranged on the side.
  • the wire feed (11) takes place from a reel (18), two such reels (18) being attached to a two-arm support (20) rotatably mounted on a column (19), in such a way that the one reel (18) is in the working position and the other is in the waiting or loading position.
  • the mandrel pull cylinders (5) are clamped in brackets (21) and are additionally held by connecting straps (22).
