Punch, embossing and forming machine for flat material, has press part connected to punch tool via pivotally mounted lever

The press part (3) acting upon the punch tool (11) is connected to a lever (5) pivotally mounted in the machine frame. This lever is connected to the punch tool via a roller (7.1) and intermediate lever (7), so that when the press part is in the resting position, the punch tool is raised, and the press part can be moved quickly in a downwards direction without encountering any force in order for it to reach a position immediately above the flat material, subsequent movement of the press part being through the deadpoint region at a very shallow angle, in order to generate a high press or punch pressure over a short path. Once punching, embossing or forming is complete, the press part is returned to its starting position, since the kinetic energy after the deadpoint region acts in the upwards direction. The machine is used to punch, emboss and/or form flat pieces or webs of paper, plastic, laminated paper, metal or similar material.

A fluid-operated circuit for setting the top dead center (TDC) and the bottom dead center (BDC) of the punch actuation cylinder (1) in punching machines comprises a first copying distributor (5) which distributes pressurized fluid, which has a spool (5a) at one end and can be connected in output to the upper section (2a) of the chamber (2) in which the actuation cylinder (1) slides and in input to a first pump (8) for feeding low-pressure fluid and to at least one first fast-acting electric valve element (6); the spool (5a) can be pushed into position by contact by a corresponding setting element (4) with continuous micrometric movement.

Piercing or embossing machine - uses hydraulic fluid to move punch and die against workpiece before piercing

A cylinder can slide in the direction of its axis. Inside the cylinder is a double action position, on the end of which the punch is fixed. Hydraulic fluid pumped to one side of the piston moves the punch against the workpiece. With the punch stopped by the workpiece, the pressure then pushes the cylinder in the opposite direction, moving the die against the other side of the workpiece. Increase of pressure performs the actual piercing operation. The oil flow is then changed to the other side of the piston, withdrawing the punch from the workpiece. The piston moves backwards until it reaches an adjustable stop. The pressure then moves the cylinder, disengaging the die from the workpiece.
