与普通模锻液压机不同,液压楔式模锻液压机的滑块是靠滑块和框架上梁之间的楔块驱动的(图1)。滑块上表面总是与楔块下表面接触,而楔块上表面与框架上梁下表面有效地接触,因此,在滑块和驱动件间的联系是固定的,这就避免了偏心载荷时滑块倾斜。滑块的垂直导轨只承受锻造有斜度或锥度的零件时产生的水平推力。 Unlike conventional swaging presses, the wedge hydraulic slide is driven by a wedge between the slide and the upper frame (Figure 1). The upper surface of the slider is always in contact with the lower surface of the wedge and the upper surface of the wedge is in effective contact with the lower surface of the upper beam of the frame so that the contact between the slider and the driving member is fixed and this avoids eccentric load Slider tilted. The vertical guide of the slider only withstands horizontal thrust resulting from the forging of sloped or tapered parts.
