Abstract
The utility model provides a kind of flexibly positioned core, it includes locating core (1), it is characterized by: being evenly equipped with one group of groove (2) in the core cap section (1a) on locating core (1) top, slide core (3) are equipped in groove (2), at least one hole (4) is equipped on the cell wall of groove (2), it is inserted with spring (5) in hole (4), one end of spring (5) is connect with the bottom hole of hole (4), and the other end connect cooperation with slide core (3).The utility model has structure simple, easy to use, thus it is possible to vary positioning core diameter avoids the overproof problem of kidney slot concentricity in punching press kidney slot, ensure that product quality, and be easy the advantages that picking and placing in tooling after product punching press.
Description
Technical field:
It is specifically exactly a kind of for punching press kidney slot the utility model relates to a kind of locating core field of blanking apparatus
Novel elastic locating core.
Background technique:
Automobile air conditioner electromagnetic clutch belt pulley is higher to the concentricity requirement of gain, in stamping die punching press kidney slot
Since product material thickness is thicker, in punching, material flowing is larger, it is easy to middle bore deformation is caused, in order to guarantee concentricity, and positioning
Core and interporal lacuna in belt wheel are smaller, and belt wheel mesoporous deformed diameter reduces after punching, and belt wheel will firmly be stuck on locating core and be difficult to
It is removed from the molds.And if locating core and interporal lacuna in belt wheel are larger, after punching, belt wheel is easy to take out, but kidney slot is concentric
Degree again can be overproof.
Utility model content:
The utility model is exactly in order to overcome the shortcomings in the prior art, to provide a kind of flexibly positioned core.
The utility model the following technical schemes are provided:
A kind of flexibly positioned core, it includes locating core, it is characterised in that: is evenly equipped with one in the core cap section on locating core top
Group groove, is equipped with slide core in groove, at least one hole is equipped on the cell wall of groove, spring, spring are inserted in hole
One end and the bottom hole in hole connect, the other end connect cooperation with slide core.
Based on the above technical solution, there can also be technical solution further below:
The cover board being coaxially distributed is equipped on the top of the core cap section, the cover plate diameter is identical as core cap section top,
Cover board and slide core form limit cooperation.
The groove is coaxially distributed with locating core, and top is equipped with the opening being connected to core cap section top.
The axis in the hole and the axis of locating core are mutually perpendicular to.
Utility model advantage:
The utility model has structure simple, easy to use, thus it is possible to vary positioning core diameter is avoided in punching press kidney slot
The overproof problem of kidney slot concentricity ensure that product quality, and be easy the advantages that picking and placing in tooling after product punching press.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment:
As illustrated in fig. 1 and 2, a kind of flexibly positioned core, it includes locating core 1, and the locating core 1 includes core cap section 1a,
The core figure 1b being coaxially distributed is equipped in the core cap lower end section 1a, the core cap section 1a and core figure 1b is an integral structure.?
Locating core 1 is equipped with the counter sink 1c being coaxially distributed, and locating core can be fixed on to punching by the way that bolt is arranged in counter sink 1c
It cuts out on mold.
Uniformly distributed on core cap section 1a periphery there are six the grooves 2 being distributed along longitudinal direction, and the cross section of the groove 2 is round,
The top of groove 2 is equipped with the opening being connected to the top core cap section 1a, is additionally provided on groove 2 and is connected to the periphery of core cap section 1a
Longitudinal opening 2a.
Slide core 3 is equipped in groove 2, the top of slide core 3 is equipped with arc roof construction 3a, so that forming hand outside slide core 3
Shotgun shape.
The hole 4 of about two parallelly distribute ons is set in groove 2, the axis of 4 axis of hole and locating core 1 is mutually perpendicular to.
The spring 5 being coaxially distributed is equipped in each hole 4, one end of spring 5 is connect with the hole bottom surface in hole 4, the other end of spring 5
Cooperation is connect with 3 outer wall of slide core below arc roof construction 3a.
It is equipped with cover board 6 on the top of core cap section 1a, uniformly distributed on cover board 6 there are three cover screw 6a, pass through cover screw
Cover board 6 is connect by 6a with the top of core cap section 1a.The diameter of the cover board 6 is less than the diameter on the top core cap section 1a.It is described
Cover board 6 can cover a part of 2 top end opening of groove, to form limit cooperation to the top of the slide core 3 in groove 2.
Working principle:
When belt wheel mesoporous to be inserted into the core cap section of locating core, the arc roof construction on slide core top can play guiding and make
With avoiding belt wheel mesoporous from being stuck in the top of locating core.
When belt wheel mesoporous is inserted into locating core, waits punching, spring is not compressed, and slide core is under spring supporting, one
Part can protrude into the outside of core cap section periphery from the longitudinal opening of groove.Also the just covert core cap section that increases in this way
Diameter, to reduce interporal lacuna in locating core and belt wheel, it is ensured that the degree in the same direction of locating core and belt wheel mesoporous.
After punching, belt wheel mesoporous deformed diameter reduces, and slide core is under the extruding of belt wheel pore wall, to groove
Contract, in this way relative to punching when, in a disguised form reduce the diameter of core cap section, increase belt wheel mesoporous and core cap section periphery it
Between gap, avoid in the prior art belt wheel mesoporous deformed diameter diminution be difficult to so that belt wheel is just firmly stuck on locating core
The case where being removed from the molds.And limit of the cover board to slide core top, it can also be drawn out out of groove to avoid slide core.
In addition, finding that the slide core that six grooves and corresponding matching are arranged is the most suitable, is lower than according to the real condition of production
The slide core of six grooves and corresponding matching, the then uniform force of belt wheel mesoporous surrounding when being unable to ensure punching press；And it is higher than six
It is a, it will affect the structural strength of the core cap section of locating core.
