摘要： A shaped part is made by forming in a flat steel plate a thickness-reducing groove and hot-shaping and hardening the flat steel plate into a three-dimensional shape. Then the plate formed with the groove is cooled, and a piece is sheared off the cooled plate along a cut line in the groove.

摘要： A double pressure cylinder arrangement including a first pressure cylinder and a second pressure cylinder positioned in a spaced and axis-parallel relationship to the first pressure cylinder. A carrier strut is connected to a bottom side of the first pressure cylinder and the second pressure cylinder. The carrier strut includes a intermediate section. A substantially u-shaped housing element has two leg sections. Each leg section houses one of the pressure cylinders. Connection lines for driving the first pressure cylinder and the second pressure cylinder are integrated in the intermediate section.

摘要： A pressure cylinder including a cylinder housing having one end including an opening. A piston is axially displaceable within the cylinder housing. A piston rod is coupled to the piston and extends through the opening at the one end of the cylinder. A cylinder base closes off the cylinder at an end of the cylinder housing opposite the opening. The cylinder also includes a pressure chamber between the piston and the cylinder base and capable of being pressurized by a pressure medium and a switching disk for interacting with a switch to determine the position of the piston. The switching disk is displaceably positioned in the pressure chamber in frictional engagement and coaxially with the piston rod so that the switching disk passes to a starting position near the piston in response to a pressure impulse overcoming the frictional engagement when the pressure chamber is first pressurized.
