我厂双锥开卷机锥头(图1)长期漏油,原因是压环与活塞杆的孔隙大,易便板卷的铁渣落入空隙而拉伤活塞杆,双头活塞杆根部双侧圆周均有250～300毫米的拉伤,深度最大达0.5毫米,同时三层V型密封圈严重损坏。为解决这一问题,我们先用细什锦锉打去溢起的毛刺,然后用模具矩形油石,用修圆手法使外圆曲线过渡(图2),另在压环外加一层油毛 My factory double cone unwinder cone (Figure 1) long-term oil spill, because the pressure ring and piston rod aperture, easy to roll the iron slag into the gap and strain the piston rod, double-headed piston rod root both sides Circumference are 250-300 mm strain, depth up to 0.5 mm, while the three V-ring severely damaged. In order to solve this problem, we first use a thin assorted razor to spill over the spikes, and then use the mold rectangular stone, with the rounding of the outer curve of the transition (Figure 2), the other plus a layer of oil in the ring
