As preferably, upper bolster is connected with guide pin bushing by connecting portion, and connecting portion is a cylindrical shape, its inwall and guide pin bushing outer wall matched in clearance, and the connecting portion bottom is provided with stop nut; Matched in clearance easy disassembly, stop nut limit upper bolster on the one hand and move down along guide pin bushing, on the other hand guide pin bushing are fixed on the upper bolster.
As preferably, the guide pin bushing upper and lower end face is provided with circular dust cap and the following dust cap gone up, and the connecting portion cylindrical shape external diameter of last dust cap external diameter and upper bolster is complementary, and following dust cap external diameter and guide pin bushing external diameter are complementary; The dust that dust cap minimizing punch press working environment is set enters no gap linear bearing, reduces the guiding mechanism wearing and tearing, guarantees guiding accuracy.Last dust cap external diameter plays and has limited upper bolster along the guide pin bushing effect of moving up greater than connecting portion cylindrical shape internal diameter.
As preferably, last dust cap and following dust cap inwall are provided with groove, and oil sealing is set in the groove, and oil sealing and guide pillar are sealed and matched, and last dust cap is connected with the upper surface of guide pin bushing by screw; Following dust cap is connected with the lower surface of guide pin bushing by screw; Oil sealing is set makes lubricating oil can not run off, guiding mechanism can be by sufficient lubrication when guaranteeing the punch press high-speed cruising.
Compared with prior art, the utility model beneficial effect is:
1, the guide pin bushing of Punching machine mold frame is connected with guide pillar by no gap linear bearing, has reduced the gap of guiding mechanism, has guaranteed the punch press precision.
2, the guide pin bushing of Punching machine mold frame can not wear and tear, and saves production cost.
3, the friction position proofing dust and protecting of Punching machine mold frame, fully lubricated, guaranteed that punch press runs up.
