Description
Technical field：
The present invention relates to floating support, is especially a kind of taper roll bearing inner assembly shrinkage die.
Background technology：
Existing structure taper roll bearing shrinkage die has the disadvantage that, 1, inner assembly locating effect it is bad, it is not easy to put
Gentle to ajust, when not being laid flat, retainer shrinks uneven, roller shifting amount cause not of uniform size in pocket hole；When not ajusting, roller
Interfere with shrinking die lintel, roller and retainer can be weighed wounded；Ultimately result in stuck bearing, damage or the increase of vibrating noise value.2、
Inner assembly is removed from the molds more difficult after shrinking, and processing efficiency is low.3rd, shrinking die lower die is drilling, is carried out before need to quenching,
Mould manufacturing procedure is more, and difficulty is high, repaiies file heavy workload by hand, and processing efficiency is low, and mould can repair number few (lintel is more ground
Wider, pocket hole is more and more shallow, can produce interference with roller), service life is short.
The content of the invention：
Ensure that inner assembly keeps flat and is aligned with shrinking die, avoids the technical problem to be solved by the invention is to provide one kind
Weigh roller and retainer, shifting amount of the roller in retainer consistent taper roll bearing inner assembly shrinking die uniform in size wounded
Tool, convenient to take out by compression spring ejection after taper roll bearing inner assembly shrinkage die inner assembly contraction, service life
It is long.
The technical solution of the present invention is to provide a kind of taper roll bearing inner assembly shrinkage die, including upper mold and
Lower die, further includes positioning stripper, the stepped hole for positioning and guide blot nut is installed, step is symmetrically opened up on the outside of lower die
Lower die upper and lower surface is run through in hole, and lower die upper surface also opens up multiple blind holes, housed in blind hole and compress spring, the lintel in the middle part of lower die
For up big and down small trapezium structure, size is adapted to the retainer deck-siding of inner assembly, and positioning stripper correspondence offers and lower die
The arc groove that coordinates of stepped hole, positioning on stripper, also there is 2 inner assembly positioning areas and inner assembly to pick and place area respectively, interior group
Part positioning area is made of the conical surface and groove, and frustoconical bevel angle is adapted to retainer cone angle, and groove is according to the quantity decile of bearing roller
Set, inner assembly picks and places area and set for notch, and positioning stripper is installed in lower die by guide blot nut, is compressed under spring
End offsets with blind hole bottom wall, and compression spring upper end offsets with positioning stripper lower surface, in use, the holding of upper mold and inner assembly
Frame abuts against.
Using compared with prior art, the present invention has the following advantages after above structure：Make inner assembly have it is circumferentially positioned and
Axially position, ensures that inner assembly keeps flat and is aligned with shrinking die, avoids weighing roller and retainer, roller altering in retainer wounded
Momentum is uniform in size consistent, convenient to take out by compression spring ejection after inner assembly contraction；Mould difficulty of processing is small, without repairing file,
High in machining efficiency, mould can repair often (width is constant all the time after lintel grinding, and pocket depth takes higher value when designing), make
Use long lifespan.
Preferably, blind hole there are 4, it is evenly distributed in lower die.
Preferably, lower die lintel is formed by wire cutting.
Further, inner assembly positioning area and inner assembly pick and place area and are symmetrically arranged.
Brief description of the drawings：
Fig. 1 is the structure diagram under the different conditions of the present invention.
Fig. 2 is the structure diagram of the positioning stripper of the present invention.
Embodiment：
The invention will be further described with reference to the accompanying drawings and detailed description：
As shown in Figure 1, 2, it is initial and done state on the left of wherein Fig. 1, right side is forcing press pressed status, a kind of circular cone
Roller bearing inner assembly shrinkage die, including upper mold 1 and lower die 2, further include positioning stripper 3, and the outside of lower die 2 symmetrically opens up use
In the stepped hole that positioning and guide blot nut 5 are installed, stepped hole runs through lower die upper and lower surface, and 2 upper surface of lower die also opens up 4
Blind hole, 4 blind holes are evenly distributed in lower die, are housed in blind hole and are compressed spring 6, and the lintel 7 in the middle part of lower die is up big and down small
Trapezium structure, lower die lintel 7 are formed by wire cutting, its size is adapted to the retainer deck-siding of inner assembly 4, can be repaired after abrasion secondary
Number is more, service life length, and pocket depth takes higher value, is cut out by wire cutting, and difficulty of processing reduces.Positioning stripper 3 corresponds to
Offer the arc groove 33 coordinated with the stepped hole of lower die, arc groove 33 and lower die stepped hole coordinate finely tune positioning stripper and
The correspondence position of lower die, positions and is symmetrical arranged interior group with 2 symmetrically arranged inner assembly positioning areas 31 and 2 on stripper 3
Part picks and places area 32, and inner assembly positioning area 31 is made of the conical surface and groove, and frustoconical bevel angle is adapted to retainer cone angle, and groove is according to axis
Quantity of bearing roller etc. point is set, and each serves as inner assembly positioning and the effect of ejection inner assembly, it is scarce that inner assembly, which picks and places area 32,
Mouth is set, and finger enters when conveniently taking, putting inner assembly, and guarantee takes, puts inner assembly quick and precisely, and ergonomic is good.Position discharging
Plate 3 is installed in lower die by bolt and nut 5, and compression 6 lower end of spring offsets with blind hole bottom wall, compression 6 upper end of spring and positioning
3 lower surface of stripper offsets, in use, the retainer of upper mold and inner assembly abuts against, and pushes upper mold by forcing press.
