and the top end of the thickened guide pillar is fixedly connected with a limiting plate.

According to the high-precision hydraulic machine without the guide column, the damping dampers are fixedly connected above the supporting blocks, and the outside of each damping damper is sleeved with a buffer spring.

According to the high-precision hydraulic machine without the guide column, the top end of the damping damper is in interference fit with the limiting plate.

According to the high-precision hydraulic machine without the guide post, the punching grooves are fixedly connected between the middle part above the workbench and the thickened guide post and are in insertion fit.

Has the advantages that:

1. the utility model discloses in with the attached drawing 4 of conventional equipment description in relatively save the slider improve and add thick guide pillar, extend working space and safe operating degree.

2. The utility model discloses add thick guide pillar and buffer spring for the die sets and repeated opposite nature device are saved to the mould, simplify the structure, reduce the mould cost, simplify installation timing process, improve die-filling efficiency, and through adding the cooperation of pegging graft of punching press groove between thick guide pillar bottom and the workstation, the less offset in punching press in-process interval is less, and reducing error reaches high accuracy punching press effect.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
