Abstract
This utility model relates to machining manufacturing technology field, particularly relate to a kind of for automobile die processing radium cut location hole puncture drift, mainly include jumper bar and be arranged on the drift at jumper bar top, described drift is cone, the big nose circle of described conical punch is fixing with described jumper bar to be connected, and the little nose circle of described conical punch is provided with semicircle head.This utility model is installed on upper mould in use, when mould matched moulds, this punctures drift and contacts with plate, owing to drift top is small round head, so plate is first stretched, when reaching capacity, plate is punctured thus forms hole, and this hole no waste mine produces, solve early stage to process radium and cut the problem in hole, location, can simplify engineering method, save process time.
Description
Technical field
This utility model relates to machining manufacturing technology field, particularly relates to a kind of cutting for automobile die processing radium and determines
Position hole puncture drift.
Background technology
The manufacturing process of automobile includes the operations such as punching press, welding, application and general assembly, and usual automobile factory is firsthand former
Material plate is all bulk plate, so cutting into required shape and size firstly the need of by bulk plate before the punching,
In some cases, need plate is carried out radium-shine cutting, and the operation of general radium-shine cutting is the most earlier, causes radium to cut location
Hole cannot process.
Utility model content
The purpose of this utility model is to provide a kind of and punctures drift for what automobile die processing radium cut hole, location, it is possible to
Overcome early stage cannot process the problem that radium cuts hole, location.
For reaching this purpose, this utility model by the following technical solutions:
A kind of puncture drift, including jumper bar and be arranged on rushing of jumper bar top for what automobile die processing radium cut hole, location
Head, described drift is cone, and the big nose circle of described conical punch is fixing with described jumper bar to be connected, described conical punch
Little nose circle is provided with semicircle head.
As preferably, the angle between bus and the tangent line of described conical punch is 14-16 degree.
As preferably, the angle between bus and the tangent line of described conical punch is 15 degree.
As preferably, a diameter of 1-3mm of described semicircle head.
As preferably, a diameter of 2mm of described semicircle head.
As preferably, a diameter of 10-11mm of described jumper bar, a length of 20-30mm of described jumper bar.
As preferably, a diameter of 10.2mm of described jumper bar, a length of 28mm of described jumper bar.
As preferably, the bottom of described jumper bar is provided with external screw thread.
The beneficial effects of the utility model:
This utility model reasonable in design, is installed on upper mould in use, and when mould matched moulds, this punctures punching
Head contact with plate, owing to drift top is small round head, so plate is first stretched, when reaching capacity, plate be punctured from
And form hole, and this hole no waste mine produces, and solves early stage and cannot process radium and cut the problem in hole, location, can simplify engineering method, save
Process time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1-jumper bar；11-external screw thread；2-drift
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Embodiment
As it is shown in figure 1, a kind of for automobile die processing radium cut location hole puncture drift, it is adaptable to plate is being carried out
Process radium before radium-shine cutting and cut hole, location, concrete, mainly include jumper bar 1 and be arranged on the drift 2 at jumper bar 1 top, described
Drift 2 is in cone, and the big nose circle of described conical punch 2 is fixing with described jumper bar 1 to be connected, the roundlet of described conical punch
End is provided with semicircle head, and first by plate draw forming, (this punctures drift can only be after plate drawing or shaping
Use, it is impossible in drawing or forming process use), then jumper bar 1 is installed vertically in the upper mold of mould, drift 2 towards
Lower mold and stretch out outside upper mold, in order to prevent getting stuck, to install stopping means on die shoe during use, add circle on drift 2
Excellent power glue (i.e. binder), then places the plate that drawing is good, matched moulds, and drift 2 contacts plate, owing to drift top is roundlet
Head, so plate is first stretched, when reaching capacity, plate is punctured, thus forms hole, and this hole no waste mine produces, and finally opens
Mould.
Angle between bus and the tangent line of described conical punch 2 is 14-16 degree.Preferably, described conical punch 2
Bus and tangent line between angle be 15 degree.The setting of this angle both can guarantee that drift 2 was connected gently with jumper bar 1, can protect again
The aesthetics of card drift 2 profile.
A diameter of 1-3mm of described semicircle head.Preferably, a diameter of 2mm of described semicircle head.Setting of semicircle head
Put and drift can be made to make plate first be stretched when contacting with plate, puncture plate when reaching the limit of plate and form hole, semicircle
The setting of head diameter to ensure to puncture plate, and plate puncture after the size in hole meet requirement.
A diameter of 10-11mm of described jumper bar 1, a length of 20-30mm of described jumper bar 1.Preferably, described jumper bar 1
A diameter of 10.2mm, a length of 28mm of described jumper bar 1.The bottom of described jumper bar 1 is provided with external screw thread 11.Described external screw thread 11
A length of bottom jumper bar 1, start at 18mm.In use, jumper bar 1 is tightened in upper mold by external screw thread 11, arranges in upper mold
Having the female thread adapted with described external screw thread 11, internal and external threads coordinates can make firm being fixed in upper mold of jumper bar 1.
By technique scheme, this utility model provides a kind of early stage making radium and cuts the probability in hole, location, can be big
Simplify greatly operation, and this punctures drift and can save multiple structures such as drift, mould button and scrap chute, simplifies mould structure.
Obviously, above-described embodiment of the present utility model is only used to understand explanation this utility model example, and
It it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here without also all of embodiment being given
Exhaustive.All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in
Within this utility model scope of the claims.
