对国内外压力机滑块结构及滑块螺杆中心距与滑块左右尺寸的比值系数进行了研究。研究表明,压力机滑块结构不同,则压力机滑块螺杆中心距与滑块左右尺寸比值系数不同;压力机能承受偏心载荷不同,则滑块刚度也不同;加大压力机滑块螺杆中心距,能提高压力机承受偏心载荷能力,却降低了压力机滑块刚度,可通过增加滑块底板厚度来弥补刚度不足;合理的滑块结构和滑块螺杆中心距,不但可以承受大的偏心载荷,而且可提高压力机精度,大大减少压力机故障及停机时间。压力机滑块结构和压力机滑块螺杆中心距对闭式双点、四点压力机和级进模压力机、多工位压力机及压力机自动生产线、压力机精度具有重要作用。
The structure of the slider at home and abroad as well as the ratio coefficient between the slider center and the slider left and right dimensions were studied. The results show that the structure of the press slide is different, the ratio of the center of the screw of the press slide to the size of the left and right sides of the slide is different, the press can bear different eccentric load, and the rigidity of the slide is also different. , Can improve the press withstand eccentric load capacity, but reduces the press slider stiffness, can increase the thickness of the slider floor to make up for the lack of stiffness; reasonable slider structure and slider screw center distance, not only can withstand large eccentric load , But also improve press accuracy, greatly reducing press failure and downtime. Press slider structure and press slider screw center distance closed two-point, four-point presses and progressive die presses, presses and press automatic production lines, press accuracy plays an important role.
