Definitions

  • the invention relates to a shot peening system for helical compression springs.
  • the springs are transported into and through the blasting area of the centrifugal wheels by means of a drag chain, which pushes or pulls the springs placed on two rollers rotating in the same direction horizontally through the blasting system.
  • the springs are set in rotation by the rollers due to the existing frictional engagement, which should result in uniform radiation of the coil springs.
  • a disadvantage of this transport system is that, when the process parameters are not optimally adjusted, in particular the coordination between the feed rate of the drag chain, the speed of the rollers and the outside diameter of the helical compression springs, a more or less large relative movement occurs between the springs and the rollers.
  • the advantages of the shot peening system according to the invention can be seen in particular in the fact that the helical compression springs can be subjected to shot peening treatment in the pretensioned state in a simple and economical manner, and at the same time the so-called friction lines on the helical compression springs can be avoided. Both measures significantly increase the life of helical compression springs.
  • the shot peening system 1 for shot peening helical compression springs 2 essentially consists of a blasting chamber 3 with centrifugal wheels 4, two opposing collets 5 for the helical compression springs 2 which can be moved horizontally in tandem operation, and two prismatic strips arranged parallel to the blasting chamber 3 6 for transporting the helical compression springs 2 with lifting and positioning devices 7 in the loading area of the collets 5.
  • each of the two collets 5 is equipped with a feed unit 8, a clamping cylinder 9, a clamping bracket 10, two rotatable spring receptacles 11 and a blasting chamber seal 12.
  • the horizontally displaceable clamping bracket 10 is guided and supported by linear guides 13, which are provided with pipe-like covers 14, 15 for protection against direct blasting agent action.
  • the cover (14) also takes over the sealing of the blasting chamber 3 for the collet 5 located in the blasting chamber 3.
  • the rotary drive 16 for the spring receptacles 11 is arranged on the end face in the connecting space between the clamping bracket 11 and the blasting chamber seal 12.
  • the drive of the feed unit 8 is designed so that the closing force necessary for the sealing is maintained during the entire loading and unloading process.
  • the shot peening system 1 shown in FIGS. 4 and 5 has a double collet system in which the collets 5 are mechanically connected directly to one another via a common feed unit 17.
