Abstract
The invention discloses a kind of anti-swollen patterns of expanded joint contact pin, including cope plate excessively, and are set to the guide sleeve of cope plate bottom surface both side；And the guide post of one end and guide sleeve installation, the other end are installed in lower template；And it is set to the swollen type cavity plate in the middle part of cope plate bottom surface；And it is set to the fixed plate of lower die plate top surface；And it is set to the flange cavity plate on the upside of fixed plate；And it is set to the blank holder on the inside of flange cavity plate；And it is set to the swollen type punch-pin on the inside of blank holder and fixed plate；The swollen type punch-pin and the activity of swollen type cavity plate are mutually embedding；The L-type force-applying piece for further including and being made into integration on the outside of swollen type cavity plate；And the annulus locating piece being made into integration with L-type force-applying piece, and with the outer locating part that is set on the inside of annulus locating piece；And the interior locating part being made into integration with swollen type cavity plate inside upper part.The anti-of the present invention crosses the swollen pattern of expanded joint contact pin, is limited by the outer locating part and interior locating part of swollen type cavity plate inner side and outer side, preventing its excessive bulging from causing, workpiece is scrapped or workpiece quality is affected.
Description
Technical field
The present invention relates to a kind of swollen patterns, and in particular to one kind is anti-to cross the swollen pattern of expanded joint contact pin, belongs to technical field of mold.
Background technology
Bulging belongs to elongation forming；It forces blank thickness to be thinned and increases with surface area under the action of mold, to obtain
The processing method for stamping of part geometry shape is called bulging, and bulging is carried out on tablet blank and is processed into pcketing；It is in tablet
Local pcketing hole bulging die is thinning by deformed area part sheet thickness, surface area increases to realize；Bulging time-varying
Material in shape area can not possibly be shifted to outside deformed area, and the material outside usual deformed area is not also supplemented into deformed area, this swollen
Be formed as pure bulging.When tablet blank part bulging, such case is generally belonged to.Bulging belongs to elongation class forming；Bulging mistake
Journey, which summarizes, not will produce Instability wrinkling phenomenon, and workpiece surface is very smooth when bulging is abundant；It is existing to be directed to the swollen of connection sheet
Pattern is perfect not enough, be easy to cause excessive bulging, leads to connection sheet deformation or compromised quality.
Invention content
（One）Technical problems to be solved
To solve the above problems, the present invention proposes, one kind is anti-to cross the swollen pattern of expanded joint contact pin, can prevent swollen, effective guarantor
Protect connection sheet safety.
（Two）Technical solution
The anti-of the present invention crosses the swollen pattern of expanded joint contact pin, including cope plate, and is set to the guide sleeve of cope plate bottom surface both side；And
The guide post of one end and guide sleeve installation, the other end are installed in lower template；And it is set to the swollen type cavity plate in the middle part of cope plate bottom surface；And
It is set to the fixed plate of lower die plate top surface；And it is set to the flange cavity plate on the upside of fixed plate；And it is set on the inside of flange cavity plate
Blank holder；And it is set to the swollen type punch-pin on the inside of blank holder and fixed plate；The swollen type punch-pin and the activity of swollen type cavity plate are mutually embedding；Also
The L-type force-applying piece for including and being made into integration on the outside of swollen type cavity plate；And the annulus locating piece being made into integration with L-type force-applying piece, and with
The outer locating part being set on the inside of annulus locating piece；And the interior locating part being made into integration with swollen type cavity plate inside upper part.
Further, the outer locating part and flange cavity plate top are mutually embedding.
Further, it is bonded at the top of annulus locating piece when downlink and flange cavity plate.
（Three）Advantageous effect
Compared with prior art, the anti-swollen pattern of expanded joint contact pin excessively of the invention, swollen type cavity plate is chimeric with swollen type punch-pin to carry out
Bulging is limited by the outer locating part and interior locating part of swollen type cavity plate inner side and outer side, prevents its excessive bulging from leading to work
Part is scrapped or workpiece quality is affected, and can improve workpiece quality and working efficiency.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the overlooking structure diagram of the present invention.
Specific implementation mode
The anti-swollen pattern of expanded joint contact pin, including cope plate 1 excessively as depicted in figs. 1 and 2, and it is set to cope plate bottom surface both side
Guide sleeve 2；And the guide post 5 of one end and guide sleeve installation, the other end are installed in lower template 6；And it is set in the middle part of cope plate bottom surface
Swollen type cavity plate 3；And it is set to the fixed plate 7 of lower die plate top surface；And it is set to the flange cavity plate 4 on the upside of fixed plate；And setting
Blank holder 9 on the inside of flange cavity plate；And it is set to the swollen type punch-pin 8 on the inside of blank holder and fixed plate；The swollen type punch-pin 8 with
3 activity of swollen type cavity plate is mutually embedding；The L-type force-applying piece 10 for further including and being made into integration on the outside of swollen type cavity plate；And it is integrated with L-type force-applying piece
Manufactured annulus locating piece 11, and with the outer locating part 12 that is set on the inside of annulus locating piece；And with swollen type cavity plate inside upper part
The interior locating part 13 being made into integration.
Wherein, the outer locating part 12 and 4 top of flange cavity plate are mutually embedding.The annulus locating piece 11 when downlink and flange
4 top fitting of cavity plate.
The anti-of the present invention crosses the swollen pattern of expanded joint contact pin, after being oriented to by guide post, is driven by a power mechanism under swollen type cavity plate
Row, it is chimeric with swollen type punch-pin；Connection sheet can protect it by blank holder flexible limit, and facilitate progress swollen
Shape；Connection sheet and swollen type cavity plate can be limited by flange cavity plate, the connection sheet sound construction after processing, stability
It is high.
The anti-of the present invention crosses the swollen pattern of expanded joint contact pin, and swollen type cavity plate progress bulging chimeric with swollen type punch-pin is recessed by swollen type
The outer locating part and interior locating part of mould inner side and outer side are limited, and prevent its excessive bulging from workpiece being caused to be scrapped or workpiece quality
It is affected, workpiece quality and working efficiency can be improved.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
Think and range is defined.Under the premise of not departing from design concept of the present invention, technology of the ordinary people in the field to the present invention
The all variations and modifications that scheme is made, should all drop into protection scope of the present invention, the claimed technology contents of the present invention,
It has all recorded in detail in the claims.
