Latest Patents

One of Lang's latest patents is a drive system for a fastening tool, particularly a riveting tool. This innovative system includes a punch for fastening operations and a clamp that is axially movable relative to the punch. The clamp is designed to hold workpieces securely during the fastening process. The punch is actuated by a drive that allows for axial displacement. The drive force exerted on the punch is transmitted to the clamp through a force transmitting mechanism that features an air pressure chamber of variable volume.

Another significant patent by Lang is a hydraulic drive mechanism for a joining tool. This mechanism is designed to actuate a tool for joining at least two workpieces made of ductile material, such as through self-piercing riveting or clinching. The drive mechanism consists of a punch drive for actuating a punch and a clamp drive for securing the workpieces against an up-setting die during the joining operation. Both drives utilize piston cylinder assemblies, with the clamp drive's assembly being supported by the punch drive's piston rod. The pressure chamber of the clamp drive is connected to one of the work chambers of the punch drive, allowing pressure to be transmitted and generating the necessary clamping force.
