Abstract (en)
An upper tool for a press brake includes a push actuating section (9K, 107, 9U) for actuating upward an actuated member (17, 103P, 121) movable up and down, in a clamping force increasing mechanism such that an upper tool clamping force can be increased gradually when the actuated member (17, 103P, 121) mounted on an upper holder device (1) of the press brake is moved upward. An example of the push actuating section is a lower surface of an engage groove portion (9K) extending horizontally and formed in any of front and rear surfaces of the upper tool (9). Further, the engage groove portion (9K) is formed between a vertical position roughly the same as a holder contact surface (9F) formed at a shoulder portion of the upper tool (9) and another vertical position slightly lower than an upper end of the upper tool. <IMAGE>
