Abstract: Press systems for manufacturing hot formed structural components may be provided. The systems comprise a fixed lower body (2), a mobile upper body (3) and a mechanism configured to provide upwards and downwards press progression of the mobile upper body (3) with respect to the fixed lower body (2). The system further comprises a cooling/heating tool (10) configured to cool down and/or heat a previously heated blank having locally different microstructures and mechanical properties which comprises: upper (11) and lower (12) mating dies, and the upper (11) and lower (12) dies comprising two or more die blocks adapted to operate at different temperatures corresponding to zones of the blank having locally different microstructures and mechanical properties, and a press tool (20) configured to draw the blank, wherein the press tool (20) is arranged downstream the cooling/heating tool (10). Moreover, methods for hot forming structural components are also provided.

Abstract: A resistance welding device, comprising a frame for supporting a tool configured like a clamp with two arms arranged facing one another and having respective welding electrodes, of which a first arm is integral to the clamp and the second arm is assembled with the capacity of being moved with respect to the clamp by means of a first actuator, such that respective movements along a straight trajectory can be imparted to the arms of the clamp for moving their electrodes closer to or away from one another. One of the arms has a hollow head housing the corresponding electrode in a guided manner the tip of which is suitable for receiving the support of a component to be welded on the workpiece, the head and the electrode being able to adopt at least one standby position (A) in which the electrode is inside the mentioned head; and a working position (B), in which the tip of the electrode is arranged in or exceeds the inlet of the head, accordingly placing the component to be welded outside the head.

Abstract: IMPROVED RESISTANCE WELDING DEVICE that includes a mobile electrode in a support assisted by a spring, gas cylinder or expansion element, allowing its movement on being compressed so that the time lapse for the welding is sufficiently long to be effective, without altering the movement cycle of the press into which it is installed. The support has one or several columns, the electrode being supported sliding along one and with a rod housed on the inside of a positioning device, also axially movable, into which the small parts to be welded are received through a conduit. The positioning device, made from an insulated material, preferably ceramic, has some fixing clamps for said part until the welding is made pushed by the electrode rod through a lower window.
