The present invention provides and discloses a kind of hydraulic press rotary table of heavy-load hydraulic cylinder formula, including rotary table, connector, transition head, transmission device, copper sheathing, thrust bearing and worktable rotary supporting arrangement；The rotary table is by connector loaded on excessive head；Copper sheathing loaded on having between excessive head and rack, thrust bearing be loaded under rotary table on rack；Its main feature is that worktable rotary supporting arrangement is a floating rotating hydraulic cylinder, floating rotating hydraulic cylinder under the excessive head between rack on；Fault phenomenon etc. caused by overcoming the problems, such as and solving the roller thrust bearing of existing hydraulic press rotary table and sliding friction disk, low load and two kinds of operating modes of top load are provided, with press bigger pressure is born, the advantages that rotary drive mechanism resistance is small, and service life is long.
Description
Technical field
The invention belongs to metal rotation extrusion equipment drive mechanism technical fields, and in particular to a kind of heavy-load hydraulic cylinder formula
Hydraulic press rotary table.
Background technology
In the hydraulic press course of work, under big pressure condition, common hydraulic press rotary table is fixed.But
It is, in hydraulic press extrusion forming specialities, it is necessary to which hydraulic press rotary table can be revolved under high-pressure work state
Turn.There is the hydraulic press rotary table of two kinds of forms of sliding friction disc type or roller thrust bearing formula at present, both transmissions
Pair can not meet bigger pressure (1000t-3000t pressure) job requirement.
Roller thrust bearing formula if can not be born the slide block pressure of press at full capacity using roller thrust bearing, is used
Shaft bearing plate causes frictional force is larger to generate fault phenomenon, and roller deformation, shaft bearing plate phenomenon of rupture hydraulic press rotary table can not
Rotation and work；
Sliding friction disc type, the frictional force that specified press tonnage is brought can cause fault phenomenon between frictional disk, turn round work
Make platform active torque demand also infinitely to increase, while increase rotary drive mechanism resistance and idle work energy consumption, hydraulic press rotation work
Making platform can not rotate and work；
Invention content
The shortcomings that the purpose of the present invention is overcoming the prior art and deficiency, provide it is a kind of have bear press bigger pressure,
Anti- fault phenomenon, rotary drive mechanism resistance is small, the hydraulic press rotary table of heavy-load hydraulic cylinder formula.
To achieve the above object the technical scheme is that：
A kind of hydraulic press rotary table of heavy-load hydraulic cylinder formula including rotary table 1, connector 2, transition head 3, passes
Dynamic device 4, copper sheathing 5, thrust bearing 6 and worktable rotary supporting arrangement 7；The rotary table was loaded on by connector
On ferry；Copper sheathing loaded on having between transition head and rack 8, thrust bearing be loaded under rotary table on rack；It is special
Sign is：The worktable rotary supporting arrangement be a floating rotating hydraulic cylinder, floating rotating hydraulic cylinder mounted in transition head it
It descends between rack；Wherein：
The floating rotating hydraulic cylinder includes plunger 701, piston 702, upper copper coin 703, copper coin 704, cylinder seat 705, cylinder
Cylinder 706, sealing ring 707, cylinder cap 708, into oil outlet 709；Wherein：Cylinder body, the plunger are welded as by cylinder seat and cylinder barrel
Lower connection piston, and in cylinder body, compressed by cylinder cap and fixed, sealing ring is housed on piston and cylinder cap；Described is upper
Copper coin is mounted under piston, and lower copper coin is on the cylinder seat of cylinder body.
Gap is equipped between the upper and lower copper coin, is 3~5mm in the gap of off working state.
The substantive distinguishing features of the protrusion of the present invention and significant effect are：
By the big vertical load of floating rotating loaded hydraulic cylinder, roller thrust bearing only carries small big vertical load；Gram
Fault phenomenon etc. asks caused by taking and solving the roller thrust bearing of existing hydraulic press rotary table and sliding friction disk
The advantages that topic has and bears press bigger pressure, and rotary drive mechanism resistance is small, and service life is long.
