Description
Technical field
It is specifically a kind of to produce the blanking die that RPT stays piece draw ring the present invention relates to the production mould of tear-off tin pull ring.
Background technology
The draw ring that the body portion that RPT stays piece draw ring to refer to finger bore region can retain, the lamellar body of finger bore region claims
To stay piece.Existing to stay piece to retain mode be to stay between piece edge and tab body one breach of setting, except gap portions
Outward, stay and groove is set between piece edge and tab body, and breach is located at and stays piece top edge, blanking die is then stayed based on such
Piece retains mode and designs.The problem of presence is：Stay piece to open position to be unfavorable for opening；Groove edge stays piece edge total length to arrange,
Groove residual after staying piece to be separated with tab body in tab body is present cuts finger phenomenon.
The content of the invention
Present invention seek to address that the above mentioned problem that draw ring is produced in practical application caused by existing punching mode structure, and carry
Can make to stay piece to open conveniently for one kind, and avoid the production RPT that the generation of finger phenomenon is cut in draw ring inner edge from staying the punching of piece draw ring
Mould.
The present invention solve its technical problem use technical scheme be：
A kind of to produce the blanking die that RPT stays piece draw ring, including the lower mould of the upper mould of punching, punching, the bottom of mould is provided with one on punching
To the stamping knife being arranged symmetrically, stamping knife is annular closing structure；Correspondence is punched the stamping knife position setting of mould on the lower mould of punching
There is what is be arranged symmetrically for a pair to enter tool bore, enter the lower mould body of tool bore insertion punching, mould and mould cooperation under punching punching on, in draw ring
Stay and struck out on the lamellar body of piece two symmetrical punchings.
Using the present invention of above-mentioned technical proposal, compared with prior art, its advantage is：
The RPT produced using blanking die of the present invention stays piece draw ring, stays and only has a bit of line of weakness, draw ring between piece and tab body
The big portion in inner edge can be made flange coiled structure by flanging die, to be prevented effectively from the generation that finger phenomenon is cut in draw ring inner edge；
Stay piece and tab body to retain one section of Integral connection structure, stay piece not only conveniently to open but also difficult for drop-off, stay piece in product packaging
Utilizing status it is more preferable.
Further, preferred scheme of the invention is：
The stamping knife of the annular closing structure is crescent stamping knife.Using crescent stamping knife, draw ring inner edge can be made more to become annulus
Shape, stays piece area bigger, is conducive to printing LOGO on piece is stayed, carves characters, and is product packaging provides convenient.
Brief description of the drawings
Fig. 1 is the punching upper die structure schematic diagram of the embodiment of the present invention；
Fig. 2 is the upward view of Fig. 1；
Fig. 3 is the punching lower die structure schematic diagram of the embodiment of the present invention；
Fig. 4 is the top view of Fig. 3；
In figure：The upper mould bodies of 1-；Mould body under 2-；11- crescent stamping knives；21- crescent enters tool bore.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is expanded on further the present invention.
It is a kind of to produce the blanking die that RPT stays piece draw ring referring to Fig. 1-4, it is made up of the upper mould of punching and the lower mould of punching, upper calligraphy or painting model
The bottom of body 1 is fixed with a pair crescent stamping knives 11 being arranged symmetrically；Two on lower mould body 2 on the upper mould body 1 of correspondence
The crescent that the setting of the position of crescent stamping knife 11 is arranged symmetrically for a pair enters tool bore 21, and crescent enters mould body under the insertion of tool bore 21
2；Mould coordinates with the lower mould of punching on punching, is stayed in draw ring and struck out on the lamellar body of piece two symmetrical crescent punchings.
The crescent punching that will stay the piece left and right sides by flanging die is being made flange curling near tab body inner edge
Structure, to be prevented effectively from the generation that finger phenomenon is cut in draw ring inner edge.
To be stayed by groove mould and a bit of line of weakness will be scribed between piece lower edge and tab body, drawn so that finger enters
Ring stays piece to open when opening pop can.
Preferably feasible embodiment of the invention is the foregoing is only, not thereby limits to interest field of the invention,
The equivalent structure change that all utilization description of the invention and accompanying drawing content are made, is both contained within interest field of the invention.
Claims (2)
