Holding pad on uniformly offer it is multiple puncture cutter groove, each described puncture is equipped with one and punctures blade in cutter groove.
Further, multiple applanation head grooves are also uniformly offered on the holding pad, in each applanation head groove
A pressing punch is equipped with, the pressing punch is also equipped with multiple with blade interval setting, the upper clamp plate lower section is punctured
Lead, the lead are threaded through on the holding pad, and multiple compression springs are provided between the upper clamp plate and holding pad.
Further, the side of the header lower half groove is additionally provided with end baffle.
Further, the pressing punch, puncture location hole offered in blade and upper clamp plate, flatten punch, puncture
Same location mandril is equipped with location hole on blade and upper clamp plate.
Further, the location hole section is ellipse.
Further, the width for puncturing blade is identical with afflux pipe diameter, and the width for flattening punch is equal to collection
The half of flow tube diameter.
Compared with prior art, the utility model has the advantage of：When in use, header is seated in header lower half
In groove, it can be pressed by forcing press to upper mold seat, then upper mold seat pushes upper padding plate, and upper padding plate drives upper clamp plate and top board
Push, the header lower half groove on header upper half groove and lower template on top board clamps header, while puncturing blade up and down
Piece punctures header side wall, cuts out pore.When in use, can be directly by collection without plug is penetrated in collector tube
Liquid pipe, which is put into mould, is punched out operation.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the sectional view of the header centreless stamping die of the utility model；
Fig. 2 is the structure diagram of holding pad in the utility model；
Fig. 3 is the structure diagram of lower template in the utility model；
Fig. 4 is the structure diagram that blade is punctured in the utility model；
Fig. 5 is the structure diagram that punch is flattened in the utility model.
Embodiment
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make the scope of protection of the utility model apparent clear and definite
Define.
Refering to shown in Fig. 1 to Fig. 3, a kind of header centreless stamping die of the utility model provided by the utility model, is used
In punching press header, including upper die component 1 and lower mold assemblies 2, upper mold seat 11 that upper die component 1 includes being cascading, on
Backing plate 12, upper clamp plate 13 and holding pad 14, lower mold assemblies 2 include die holder 21 and the lower template 22 being stacked, lower template 22
On offer header lower half groove 221, header upper half groove 141, header upper half groove 141 and afflux are offered on holding pad 14
221 positions of pipe lower half groove are corresponding, and multiple puncturing blades are uniformly offered on the holding pad 14 at 141 position of header upper half groove
Groove 142, blade 3 is punctured as shown in fig.4, each puncturing and one being equipped with cutter groove 142.14 one side of holding pad is used to press
Flow tube is compacted, on the other hand punctures blade 3 for protection.When in use, header is seated in header lower half groove 221,
It can be pressed by forcing press to upper mold seat 11, then upper mold seat 11 pushes upper padding plate 12, and upper padding plate 12 drives 13 He of upper clamp plate
Top board 14 pushes, and the header lower half groove on header upper half groove 141 and lower template 22 on top board 14 clamps about 221
Header, while puncture blade 3 and header side wall is punctured, cut out pore.When in use, without plug is penetrated collection
In liquid pipe, directly collector tube can be put into mould and be punched out operation.
In the present embodiment, multiple applanation head grooves 143 are also uniformly offered on holding pad 14, as shown in fig.5, each
It is equipped with a pressing punch 4 in applanation head groove 143, flattens punch 4 and puncture blade 3 and be arranged at intervals, the lower section of upper clamp plate 13
Multiple leads 5 are also equipped with, lead 5 is threaded through on holding pad 14, is provided between upper clamp plate 13 and holding pad 14 multiple
Compress spring 6.During forcing press pushing, holding pad 14 clamps header with lower template 22 first, and then forcing press continues
Push, compression spring 6 is compressed, and upper clamp plate 13 drives to puncture blade 3 and flatten punch 4 and pushes, and punctures blade 3 and pushes to afflux
Pipe is punched out, while flattens punch 4 and punching both sides are flattened.
In order to make header accurate positioning when putting, the side of header lower half groove 221 is additionally provided with end baffle 7.
When in use, by header one section hold out against in afflux tube end.In order to make each pressing punch 4, puncture 3 relative position of blade standard
Really.Punch 4 is flattened, punctures location hole 8 is offered in blade 3 and upper clamp plate 13, punch 4 is flattened, punctures blade 3 and upper clamp plate
Same location mandril 9 is equipped with location hole 8 on 13.Preferably, 8 section of location hole is ellipse.Can further it prevent
Only flatten punch 4 or slightly rotated when puncturing 3 punching press of blade.
It is relatively thin due to puncturing 3 wall thickness of blade, puncture that the width of blade 3 is identical with afflux pipe diameter, puncture 3 end of blade
Cutter head can set half smaller, such as that header width can be arranged to by size requirement, flatten the width one of punch 4
As it is thicker, so flatten punch 4 width be equal to afflux pipe diameter half, it is possible to meet intensity requirement.
The above, is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
