Description
Technical field
The utility model belongs to high-speed railway track plate mould associated components, is specifically related to a kind of service sleeve of track plate accurately can being positioned on the track plate, and the built-in fitting servo-actuated stripper apparatus of demoulding functions is finished in the energy servo-actuated.
Background technology
Along with the fast development of China Railway High-speed, railway plate die has also had suitable vast market.Many have the company that enriches the Machine Design manufacturing experience all to begin to march this field, had the product of a lot of companies to come into operation.But, just at present, railway plate die design and produce in China also not to be very ripe, a lot of weak points in use occurred that especially the built-in fitting mould emptier is very different especially; The service sleeve that has is elastic constructions such as snap ring, loses efficacy easily, causes to have rising phenomenon and locate inaccurately in the process of re-packing, and the track plate percent defective of production is than higher; The service sleeve that has and bed die adopt connected mode such as screw thread to be connected, though there is not rising phenomenon need hand-stripping, the lengthy and tedious complexity of operating procedure lavishes labor on resource.
Summary of the invention
Service sleeve floats and pinpoint problem the utility model in the prior art in order to solve, and reduces human resources, and a kind of built-in fitting servo-actuated stripper apparatus is provided.
The utility model adopts following technical scheme to realize: built-in fitting servo-actuated stripper apparatus, comprise interior axle, clamp nut is established in an interior axle lower end, the sheathed sealing ring in position that interior axle is positioned at bed die top and joins with bed die, interior axle upper end is that up-small and down-big variable-diameter structure and its outside is with internal axle axial motion relatively, and circumferentially fixing outer shaft, have big outer little shoulder hole at least two on the outer shaft, establish the steel ball in the internal thread groove that can be arranged in service sleeve in the shoulder hole, interior axle is connected by threaded rod with outer shaft, leave demoulding space on the threaded rod, the sheathed spring in screw rod position at place, demoulding space.
Axle top in threaded rod can be arranged at, and pass outer shaft, wear on the inside and outside axle and can prevent the two alignment pin in relative rotation, leave demoulding space and sheathed spring on the threaded rod outside the outer shaft.
Threaded rod also can pass outer shaft and interior axle from top to bottom, interior axle bottom is welded with and prevents interior axle and threaded rod location-plate in relative rotation, the threaded rod top is fixed on the outer shaft top, and the threaded rod bottom passes the location-plate bottom, leaves demoulding space and sheathed spring on the threaded rod outside the location-plate.
The utility model and bed die are one, the mode that axle matches with outer shaft in adopting, the relative internal axle axial motion of outer shaft, circumferentially fixing.Make in outer shaft being enclosed within tightly on the axle with spring, interior axle is variable-diameter structure (can be the ladder form), on outer shaft, open at least two shoulder holes, put into a steel ball in each shoulder hole respectively, steel ball can be arranged in the internal thread groove of service sleeve, its trajectory is consistent with the internal thread of service sleeve, plays the function of trapezoidal thread.Because the shoulder hole of outer shaft is interior big outer little, and steel ball is put into from interior, so can not drop out, innerly steel ball ejected an outer shaft part with interior thick one section, realize its screw thread function.Then service sleeve is tightened with it by internal thread, by the elastic force of spring inside and outside axle is tightly forced together, so that service sleeve is when tightening, steel ball and outer shaft can not move up.At this moment, the beginning casting cement, after treating that cement fully solidifies, begin cement plate upwards to be sling with crane, at this moment, service sleeve can be followed cement plate and be moved up, outer shaft and steel ball also move up thereupon, during thin one section of axle, steel ball begins to move to inside in steel ball moves to, and a part that is projected into outer shaft begins to shrink, lose and being threaded of service sleeve, service sleeve just separates along with cement plate is sling with this mechanism, and outer shaft or interior axle are got back to original state with steel ball under the effect of spring, finished whole demoulding functions.
The beneficial effects of the utility model are that the curved-line thread path and the service sleeve internal thread that utilize steel ball to form tighten together, and have prevented the come-up of service sleeve in the process of re-packing.The mode that axle and outer shaft are separated in adopting, the function of the realization service sleeve servo-actuated demoulding has significantly reduced workman's workload, thereby has improved production efficiency.
