Abrégé

A tie bar tensioning system that allows a bending machine operator to removably couple an upper end of a bend die post of the bending machine to a base of the bending machine via a tie bar, and to lock the tie bar in a tensioned position. The tensioning system includes a stationary member and a rotatable member, each with aligned tie bar passages for receiving the one end of the tie bar. Both the stationary member and the rotatable member include respective engagement surfaces, with the rotatable member engagement surface being rotatable relative to the stationary member engagement surface between a released position and a tensioned position whereat the rotatable member is selectively lockable. The rotation of the rotatable member with the stationary engagement surface in engagement with the stationary engagement surface longitudinally displacing the rotatable member relative to the stationary member.

Systems and methods for providing tube end forming equipment or machines that utilize the advantage of hydraulic power without having the constant noise, heat, and energy usage associated with traditional hydraulic power units. The end forming machine includes a hydraulic pump that is operated only when a demand from the system for oil pressure/flow is present. This is accomplished by providing a synchronous servo motor and servo drive coupled to a fixed displacement hydraulic pump. The oil pressure of the system is monitored to detect when the pressure drops below a preset value to provide closed-loop control of the servo motor. The servo motor is controlled to rotate the hydraulic pump at the required speed (up to the maximum RPM of the motor/pump combination) as necessary to obtain the desired system pressure during the tube end forming process.

• B21C 19/00 - Dispositifs pour redresser le fil métallique ou d'autres produits analogues combinés à des machines ou des appareils à étirer ou à enrouler, ou spécialement conçus pour travailler en association avec ces machines ou ces appareils
• B29C 57/04 - Tulipage ou évasement, p. ex. combiné à la formation d'une rainure utilisant des moyens mécaniques
• B21D 41/02 - Élargissement
• B21D 19/00 - Mise en forme ou autres traitements des bords, p. ex. des bords des tubes
