Specific embodiment
The gear shaft splined hole cold extrusion press by frame 1, be oriented to slide bar 2, extrusion oil cylinder 3, mold base 4, jacking cylinder 5,
Dividing plate 6, dividing plate seat 7 and extrusion head 8 are constituted；By being oriented to the activity of slide bar 2 equipped with extrusion head 8 in frame 1；Set on extrusion head 8
There is extruding spline tooth 15；The top of extrusion head 8 is fixed with extrusion oil cylinder 3 by installing plate 9, and extrusion oil cylinder 3 is connected with extrusion head 8
Connect；Extrusion oil cylinder 3 can drive extrusion head 8 to be moved up and down along slide bar 2 is oriented to.
The lower section of extrusion head 8 is fixed with mold base 4；Mould through hole 11 is provided with mold base 4；Mould through hole 11 and extrusion head
8 is concentric；Mould through hole 11 is corresponding with gear shaft profile to be processed.
By parting bead 9 equipped with dividing plate seat 7 on mold base 4；Activity is fitted with dividing plate 6 in dividing plate seat 7, is provided with dividing plate 6
Guide through hole 10 corresponding with extrusion head 8；Set parting bead 9 purpose be：So as to have between dividing plate 6 and mold base 4 certain
Gap.One end termination of dividing plate seat 7 is provided with limiting plate 12.Set limiting plate 12 purpose be：So that dividing plate 6 is every time
Can insert to specified location, so that guide through hole 10 is corresponding with extrusion head 8, the hair of accident be contradicted when preventing extrusion head 8 from moving down
It is raw.
The lower section of mold base 4 is provided with jacking cylinder 5.The piston head of jacking cylinder 5 is slidably connected with mould through hole 11.
Guide post 13 is provided with frame 1；Guide sleeve hole 14 is provided with the extrusion head 8 of the top of guide post 13；Guide post
13 is corresponding with guide sleeve hole 14.After extrusion head 8 moves down a segment distance, guide sleeve hole 14 is understood and the sliding contact of guide post 13,
The purpose being arranged such is：Guide extrusion head 8 to be moved down by intended trajectory by guide post 13, prevent the generation of skew accident.
When the gear shaft splined hole cold extrusion press works, it is necessary first to extract dividing plate 6 out from dividing plate seat 7；To then treat
The gear shaft of blank hole that is provided with of processing is placed in mould through hole 11；The now bottom of gear shaft to be processed and jacking cylinder
5 contradict connection；Then powdered lubricant is respectively coated with the blank hole of gear shaft and the extruding spline tooth 15 of extrusion head 8.Then
Dividing plate 6 is installed in place.
After above Job readiness is finished, start extrusion oil cylinder 3, extrusion oil cylinder 3 can drive extrusion head 8 to pass through guide through hole 10
Afterwards, the blank hole of gear shaft is extruded by extruding spline tooth 15, and spline is squeezed out in blank hole, form splined hole.When
After the extruding of extrusion head 8 is finished, extrusion oil cylinder 3 can drive extrusion head 8 to reset, and in this course, extrusion head 8 can band movable gear shaft
Upper together to move, when gear shaft and dividing plate 6 are contradicted, dividing plate 6 can block gear shaft, it is separated with extrusion head 8, now gear
Axle can be fallen into mould through hole 11 in the presence of self gravitation.Then manually dividing plate 6 is extracted out, and start jacking cylinder 5, pushed up
Oil-lifting jar 5 can be by the gear shaft of completion of processing, and part ejection die through hole 11 then manually removes the gear shaft of completion of processing,
Subsequent jacking cylinder 5 can reset, and so far the cold extrusion press is fully completed the processing of gear shaft splined hole, can then enter next
Working cycles.
The gear shaft splined hole cold extrusion press, it is simple structure, easy to use, cheap；Solve existing Full-automatic machine
The purchase cost that has of bed problem high and difficult in maintenance, meets the production of medium-sized and small enterprises high-volume processing gear shaft splined hole
Need.
