DEVICE precise adjustment of the closed height of mechanical presses

摘要

The invention relates to forging and stamping equipment, in particular for mechanical presses. Control unit Shut height mezhshtampovogo space consisting of a position sensor of the slider and actuated motor Shut height adjustment mechanism comprising an eccentric bushing disposed in the lower heads of the double connecting rod or single rod and associated lever with screw drive consisting of a nut fixed to the lever, and a screw connected to the telescopic cardan shaft, which driving part is connected to set a bearing on a fixed bracket on the press frame, washed the weft shaft, which sleeve is connected to the motor shaft or an output shaft of the driving gear, the input shaft of which is connected to the motor shaft, wherein as the motor used synchronous motor connected to the mains through a frequency converter configured to control on an industrial computer or a programmable logic controller whose inputs are connected to the slide position sensor and an encoder, serving for registering the angle of rotation of the shaft of the synchronous e ektrodvigatelya and its angular velocity. The apparatus enables automatic adjustment of the closed height of the mechanical press during the working cycle without stopping the operation of the press. Fct 1, 2 of FIG.
