ABSTRACT:
The working machine comprises a first (ET) and a second (TT) machining means, at least the first one (ET) being arranged to move in relation to the machine body (28) towards the second one (TT), to accomplish machining of a sheet material, wherein the sheet material to be worked is placed between the machining means (ET) and (TT). At least one of the machining means (ET and TT) is provided with means (7, 9) for conducting the transfer and working movements of said tool (ET, TT). The first part (7) of the means is fixed to the machining means (ET, TT), and the second part (9) of the means is fixed to the machine body (28), to be movable in relation thereto by actuators (10, 11, 14-26, 39, 41) in the machine body (28). The movement of the second part (9) of the means (7, 9) in relation to the machine body (28) during machining based on pressing of the sheet material is transmitted from the second part (9) to the first part (7) by a contact surface connection. The first part (7) and/or the second part (9) of the means (7, 9) is equipped with at least one guide surface part (36) which is formed as a bevelled surface in relation to the direction of movement of the machining means (ET, TT). The position of the contact surface connection between the first part (7) and the second part (9) of the means in relation to the guide surface part (36) will define the position of the machining means (ET, TT). According to the invention, the guide surface part (36) is provided with at least a first portion (36a) for conducting the transfer movements of the machining means (ET, TT) and a second portion (36b) for conducting the working movements based on pressing of the sheet material to be worked with the machining means (ET, TT).
