Abstract
The invention discloses a kind of seal closure piercing dies, including cope plate and lower template and one end to be set to the guide post of cope plate bottom surface, and the other end is installed with stripper cooperation；And it is set to the punch-pin in the middle part of stripper bottom surface, and it is set to the die shank at the top of cope plate, and it is set to the fixed plate of cope plate bottom surface, and it is set to the die socket in lower template, and it is set to re-entrant mold in die socket, and it is set to the positioning plate above cavity plate, it is characterised in that：It further include the holding pad for being set to stripper bottom；And it is set to the positioning tube on the outside of punch-pin；The punch-pin is provided with independent pressure mechanism.The seal closure piercing die of the present invention, and pass through forcing press downlink, by holding pad workpiece pressing material, ensure workpiece material not sideslip, while being accurately positioned by positioning tube and the cooperation of lower positioning tube, after completing positioning, punch-pin is driven directly to be punched out by aerodynamic pressure mechanism, its high punching efficiency, punching is accurate, and ensures smooth do not have burr at punching.
Description
Technical field
The present invention relates to a kind of piercing dies, and in particular to a kind of seal closure piercing die belongs to technical field of mold.
Background technology
In the prior art, punching process has two major classes：One kind is common stamping, and another kind of is fine-edge blanking, production practices
It proves, due to there is gap, making the material fallen or the hole gone out all with tapered, the big end ruler of blank between punch and matrix
Very little to be equal or close to cutting edge of die size, the small end size of punching part is equal or close to punch-pin Blade dimensions；Measure with
In use, blank is on the basis of big end size, punching aperture is on the basis of small end size；When punching, punch-pin and cavity plate
It to rub with product or waste material, punch-pin more grinds smaller, and cavity plate the more grinds the more big, so that gap is more used bigger；Thus true
When fixed mold Blade dimensions and its manufacturing tolerance, following principles need to be followed, when blanking, first determine cutting edge of die size；Punch-pin sword
The basic size of mouth takes the minimum limit of size close or equal to product, to ensure cavity plate abrasion in a certain range, can rush
Go out qualified product, the basic size of punch-pin cutting edge then reduces a minimum operational gap width by cutting edge of die basic size and comes really
It is fixed；When punching, punch-pin Blade dimensions are first determined；The basic size of cutting edge of die takes the maximum limit of size close or equal to hole,
To ensure that punch-pin abrasion still can be used in a certain range, and the basic size of cutting edge of die is added by the basic size of punch-pin cutting edge
A upper minimum operational gap width determines；The manufacturing tolerance of punch-pin and cutting edge of die, depend primarily on blanking part precision and
The accuracy of manufacture of shape, general mold is at least 1~2 grade higher than the precision of blanking part；In the prior art, seal closure punching is easy production
Setation pierces, and in punch process, is easy to cause to deform to area near seal closure.
Invention content
（One）Technical problems to be solved
To solve the above problems, the present invention proposes a kind of seal closure piercing die, end cap punching error is small, and de- material is light
Pine.
（Two）Technical solution
The seal closure piercing die of the present invention, including cope plate and lower template and one end are set to the guide post of cope plate bottom surface,
Its other end is installed with stripper cooperation；And it is set to the punch-pin in the middle part of stripper bottom surface, and it is set to the mould at the top of cope plate
Handle, and be set to the fixed plate of cope plate bottom surface, and the die socket that is set in lower template, and be set to recessed on the inside of die socket
Mould, and it is set to the positioning plate above cavity plate, it is characterised in that：It further include the holding pad for being set to stripper bottom；And setting
Positioning tube on the outside of punch-pin；The punch-pin is provided with independent pressure mechanism.
As preferred embodiment, the lower positioning tube with positioning tube edge face is provided at the top of the cavity plate.
As preferred embodiment, rubber is provided between the fixed plate and stripper.
（Three）Advantageous effect
Compared with prior art, seal closure piercing die of the invention, and by forcing press downlink, by holding pad workpiece pressing
Material ensures workpiece material not sideslip, while being accurately positioned by positioning tube and the cooperation of lower positioning tube, after completing positioning, passes through
Aerodynamic pressure mechanism driving punch-pin is directly punched out, and high punching efficiency, punching is accurate, and ensures smooth do not have hair at punching
Thorn.
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
Seal closure piercing die as depicted in figs. 1 and 2, including cope plate 2 and lower template 8 and one end are set to cope plate
The guide post 11 of bottom surface, the other end are installed with the cooperation of stripper 5；And it is set to the punch-pin 10 in the middle part of stripper bottom surface, and setting
Die shank 1 at the top of cope plate, and be set to the fixed plate 3 of cope plate bottom surface, and the die socket 7 that is set in lower template, and
Re-entrant mold 9 in die socket are set to, and are set to the positioning plate 6 above cavity plate, further include the binder for being set to stripper bottom
Circle 12；And it is set to the positioning tube 13 on the outside of punch-pin；The punch-pin 10 is provided with independent pressure mechanism.
9 top of the cavity plate is provided with the lower positioning tube 14 with positioning tube edge face.
Rubber 4 is provided between the fixed plate 3 and stripper 5.
The seal closure piercing die of the present invention, and holding pad workpiece pressing material is ensured not by workpiece material by forcing press downlink
Sideslip, while being accurately positioned by positioning tube and the cooperation of lower positioning tube, after completing positioning, by aerodynamic pressure, mechanism drives
Punch-pin is directly punched out, and high punching efficiency, punching is accurate, and ensures smooth do not have burr at punching.
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.
