Description
Technical field
The present invention relates to Workpiece shaping mechanical field, specifically, particularly relates to a kind of lining volume circle discharging frock
Device and method.
Background technology
Lining is a kind of cirque structure, in each bearing of automobile dynamic system, reduces the abrasion of bearing.
One important step of the processing of existing lining rolls up circle exactly, namely the sheet metal of sheet is rolled into annulus
The lining blank of shape.In actual production, the precision due to the elasticity of sheet metal self and mould is inadequate, once rolls up
Lining seam crossing circularity after circle cannot meet requirement, and for ensureing that the circularity of lining meets the requirements, workman needs hand
Hold circle_curling die axle to rotate, workpiece is carried out the punching press in two to three orientation.This traditional processing method exists
Labour intensity is high, working (machining) efficiency is low, and workman is during constantly rotating circle_curling die axle, once occurs
Carelessness, as easy as rolling off a log generation security incident, bring serious personnel and property loss.Meanwhile, existing circle_curling die
Axle can not meet industrial requirements in intensity and anti-wear performance, some circle_curling die axle intensity improve in the case of,
Wearability it cannot be guaranteed that, become the short slab in device service life.

When using this frock, base plate (1) is horizontally arranged on circle_curling die tool, for the first time after the punching press of volume circle, and volume
Circle bush ring is enclosed within circle_curling die axle (9), by the rotation of whirligig (7), second can be carried out,
Three punching presses, carry out multi-faceted punching press to volume circle lining, are greatly improved the volume circle precision of volume circle lining；Complete
After volume circle stamping procedure, assembly (6) is driven to drive slide plate (5) to drive circle_curling die axle (9) rearward movement,
Snare lining on circle_curling die axle (9) departs from circle_curling die axle (9) under the effect of shelves fork (10) and falls into
In blanking raceway (11), finally roll into body feed tank.
By this frock, rotation and the discharging of circle_curling die axle (9) can be automatically performed, and considerably reduce
Labour intensity, and therefore, reduce industrial accident and occur, improve production efficiency and produce into reducing
This.
The mode using air cylinder driven can meet functional requirement, is easily achieved again, and source of the gas is in factory also simultaneously
The abundantest, it is not necessary to additionally to increase equipment, thus reduce production cost.
Being symmetrical arranged two groups drives assembly (6) to can ensure that slide plate (5) does not occurs during slide anteroposterior
Clamping stagnation, improves production efficiency.
Due to lining specification different sizes, the size of circle_curling die axle (9) is the most different, for different size
Circle_curling die axle (9) only need to be equipped with the guided mode flange (12) of corresponding size, guided mode flange (12) is arranged on
On front end panel (2), thus realize the processing that a set of frock is adapted to the lining of plurality of specifications, further
Reduce production cost.
The front-end and back-end of circle_curling die axle (9) of the present invention are defined as: with the mistake of front end panel (2)
The direction that hole contacts with the prong in the middle of shelves fork is front end, and opposite side is rear end；As preferably, by circle_curling die
Axle (9) is halved, and the direction that the prong middle with the via of front end panel (2) and shelves fork contacts is front end,
Opposite side is rear end.
Beneficial effect:
I, the present invention can be good at substituting artificial rotation circle_curling die axle, has the labour intensity reducing workman,
The advantage improving production efficiency；
II, owing to being improved the material of circle_curling die axle, is carrying out excellent to Cr12MoV component content
Change, and with the addition of rare earth element wherein, it is ensured that its performance such as intensity and wearability so that device lifetime
Significantly extended；
III, have employed specific heat treatment mode and processes Cr12MoV circle_curling die axle so that it is at different parts
Meet the requirement of intensity and anti-wear performance respectively, enhance volume circle quality；
IV, has carried out concrete restriction to the microstructure of Cr12MoV circle_curling die axle so that its intensity and wear-resisting
The stability of property is improved；
V, special rampman assembles and closes the circle_curling die axle with property so that the performance of this frock obtains greatly
Width improves, and the two technique effect coordinated not is simple superposition, but creates and individually can not possess
Technique effect.

Lining volume circle device for discharging produces；When each volume justifies punching press, circle_curling die axle stretches out before stamping, and volume is justified
Whole punching press is retracted after completing, and volume circle carries out the punching press in three directions, and the bush ring of volume circle is enclosed within circle_curling die axle
(9) on, by the rotation of whirligig (7), after punching press, whirligig drives circle_curling die axle to turn each time
Dynamic 60 degree of impacts complete a volume circle part for three times, after completing to roll up round stamping procedure, drive assembly (6) to drive
Dynamic slide plate (5) drives circle_curling die axle (9) rearward movement, and snare lining on circle_curling die axle (9) is at shelves
Depart from circle_curling die axle (9) under the effect of fork (10) to fall in blanking raceway (11), finally roll into body feed tank.
The production method of lining the most according to claim 6 volume circle, it is characterised in that: under mould
Mould arranges whether sensor detection part placement completes.
The production method of lining the most according to claim 6 volume circle, it is characterised in that: first lining is rolled up
The circle_curling die axle (9) of circle device for discharging is heat-treated, and described heat treatment step is:
I, uses local heat treatmet to the front end of circle_curling die axle (9), uses local heater to be heated to front end
1000～1062 DEG C, carrying out oil quenching after insulation 6～12min, quenching final temperature is 15～32 DEG C；Aligning calibration
After, it is tempered in the case of 110～130 DEG C；Then entirety carries out subzero treatment, and chilling temperature is
-38～-98 DEG C, after insulation 6～8min, slow heat is to room temperature in atmosphere；
Ii, uses local heat treatmet, to the volume after the entirety subzero treatment of step i to the rear end of circle_curling die axle (9)
The rear end of circle mold shaft (9) carries out the plasma nitrocarburizing of rare earth RE, the plasma nitrogen of described rare earth RE
It is 500～528 DEG C that carbon oozes the treatment temperature of process altogether, NH3: CO2Volume ratio be (8～16): 1, furnace pressure
It is 520～720MPa；The plasma sputtering of rare earth RE is carried out while nitrocarburizing.
