A weld cylinder having a single piston arrangement is provided. The cylinder has a movable retract piston assembly with the piston arranged within the retract piston assembly. The piston supports a rod that is movable between home, intermediate, work, and advanced work positions. The rod moves rapidly from the home position to the intermediate position however, the rod moves more slowly from the intermediate position to the work position to reduce the impact force. A cushion chamber slowly exhausts through a pre-orifice and a hole in the cushion valve while an isolator is in an open position. Once the cushion valve opens in response to a retract-forward pressure on the cushion valve, the cushion chamber exhausts rapidly so that weld force increases rapidly to minimize increases in cycle time. Advance of a retract piston assembly is also cushioned. A weld-forward port is no longer provided on a cylinder barrel.

L'invention propose un cylindre de soudage ayant un arrangement de piston simple. Le cylindre comporte un ensemble de piston de retrait mobile avec le piston disposé à l'intérieur de l'ensemble de piston de retrait. Le piston porte une tige qui est mobile entre des positions repos, intermédiaire, travail et travail avancé. La tige se déplace rapidement de la position repos à la position intermédiaire, cependant elle se déplace plus lentement de la position intermédiaire à la position travail pour réduire la force d'impact. Une chambre d'amortissement échappe lentement par un pré-orifice et un trou dans la soupape d'amortissement tandis qu'un isolateur est en position ouverte. Une fois que la soupape d'amortissement s'ouvre en réaction à une pression de retrait avant sur la soupape d'amortissement, la chambre d'amortissement échappe rapidement de sorte que la force de soudage augmente rapidement pour éviter le plus possible les augmentations de durée de cycle. L'avance de l'ensemble de piston de retrait est aussi amortie. Le baril du cylindre n'est plus équipé d'un port de soudage avant.
