The present invention realizes through following organization plan: a kind of slide block is regulated the screw-threaded coupling structure, mainly is made up of adjusting screw(rod), Adjusting bolt Adjusting screw, piston, latch, terminal pad, slide block, cavity, hydraulic oil import and oil resistant sealing ring.Wherein, The inner chamber of Adjusting bolt Adjusting screw is designed with large and small two internal diameters; Adjusting screw(rod) and piston also are designed with large and small two external diameters respectively, and plunger designs is the hollow structure with inner chamber, and the internal thread in the external screw thread of the big external diameter of adjusting screw(rod) and Adjusting bolt Adjusting screw are little on wall screws screwed connection; The internal thread of the external screw thread of the terminal little external diameter of adjusting screw(rod) and the hollow wall of piston screws screwed connection; Latch is fixedly connected with piston base, and the draw-in groove of two outer walls of piston size is fixedly connected with the screens of oil resistant sealing ring, being dynamically connected for two-stage piston/cylinder sealed sliding of the large and small outer wall of piston and the large and small internal diameter of Adjusting bolt Adjusting screw; The cavity that forms in hydraulic oil import and piston and the Adjusting bolt Adjusting screw inwall sliding stroke is that circulating oil path is connected; Piston is fixedly connected with terminal pad, and Adjusting bolt Adjusting screw is fixedly connected with terminal pad, and terminal pad is fixedly connected with slide block.
Operation principle: the pressure of punch press and forcing press conducts to adjusting screw(rod), spins together owing to have the Adjusting bolt Adjusting screw of internal thread and have the external screw thread adjusting screw(rod).When external force is conducted to adjusting screw(rod); Adjusting screw(rod) rotates along the internal thread of Adjusting bolt Adjusting screw and plunger shaft inwall; Because latch both was fixedly connected with piston, was fixedly connected with terminal pad again, so when piston receives downward pressure, do not rotate; Piston and Adjusting bolt Adjusting screw are static relatively, are not moved.But because the high frequency enormous impact power of punch press and forcing press can cause vibration to the flight pitch of adjusting screw(rod) and piston and Adjusting bolt Adjusting screw.Each vibration all can be decomposed into downforce and the stress that makes progress; Downforce can let piston slide along the Adjusting bolt Adjusting screw inwall and produce small slip downwards; Owing to piston/cylinder structure and sealing reason must produce cavity, cavity inside negative pressure will occur and suck hydraulic oil, meanwhile; Negative pressure and cavity can produce upwards bounce elimination cavity with the stress that makes progress, and lets air pressure return zero.The phenomenon of cavity and zero-pressure and negative pressure will frequently appear in frequent vibration; Because the reaction force that negative pressure and cavity forms is a kind of reverse flexible elastic force; This flexible elastic force can reduce vibration of internal and external threads spacing and friction; Guarantee the accuracy of native system structure, can alleviate the axial skew inclination angle of piston that the excesssive gap of screw thread causes 3.Because the pitch of big minor thread is consistent, piston 3 is decided to be connected the wearing and tearing that oil resistant sealing ring 9 is also avoided in design with Adjusting bolt Adjusting screw solid 2, makes hydraulic locking effective for a long time, can adorn mould under the slide block and be used for work.
Beneficial effect of the present invention: the present invention has rational in infrastructure, characteristics such as system is accurate, long service life, product are stable, good in economic efficiency, safe and reliable to operation.
