××厂在设计制造一批精密多工步级进模时,由于凸模多(有冲孔、落料、冲沉孔及压筋)。而且各成形凸模需保持一定的相对尺寸。另外,在冲裁凸模刃磨后需再调整成形凸模的高度,这样就造成零件的加工装配及维修上的不方便。现在应用了一种使凸模高度可调的机构,此机构能使在装配、校模及维修模具时,只要根据实际需要即可精确地调整凸模的轴向位置。其机构原理是在凸模上端面装有滑块,而滑块一端开有T形槽,槽中按放螺杆的肩 × × plant in the design and manufacture of a number of precision multi-step progressive die, due to punch more (punching, blanking, punching holes and pressure tendons). And the forming punch to maintain a certain relative size. In addition, the punching punch grinding after the need to reshape the height of the forming punch, thus causing the parts assembly and maintenance of the inconvenience. Now a punch height adjustment mechanism that allows the assembly, calibration and repair of molds, as long as the actual need to accurately adjust the axial position of the punch. The principle of its mechanism is in the upper surface of the punch equipped with a slider, and the slider opened at one end of the T-shaped groove, the groove press the shoulder of the screw
