Abstract
The present invention discloses a kind of forging multipart punch, including lower mould and drift corresponding with lower mould, and the drift includes punch-holder shank, and the upper end of punch-holder shank is fixed by screws on upper padding plate；The lower end of the punch-holder shank sets cutting blade, and the cutting blade is bolted on the lower end of punch-holder shank；External diameter of the external diameter of punch-holder shank less than cutting blade；Loose plug is socketed on punch-holder shank, and the upper end of loose plug abuts with the spring being set on punch-holder shank, and the upper end of spring abuts with upper padding plate；The lateral profile of the loose plug is corresponding with the side profile of forging endoporus.It is an advantage of the invention that：Due to the setting of loose plug, first it is the endoporus sidewall contact of loose plug and forging when can ensure and be punched, endoporus side wall is supported in advance, ensure that and will not produce larger deformation in punch process, additionally, in drift lifting process, due to the effect of spring, loose plug has certain pressure to forging, it is to avoid shrinks and the situation that forging encases drift and cannot come off occurs in hole.
Description
Technical field
The invention belongs to the field of forging, thin-walled forging endoporus gross weight is removed specifically in die forging production process
When it is a kind of prevent forging thin-walled occur punching deformation mould.
Background technology
There is variously-shaped hole shape structure in the general portion in the product of the forging products such as some connecting rods, flange, wheel hub, in forging process
Middle needs get rid of the gross weight in hole, and the die forging production technology of this kind of forging products is generally comprised：Heating, blocking, finish-forging, cut
The operations such as side, punching, correction, can form certain thickness gross weight in finish-forging process hole, and punching is to by forging using drift
Gross weight is got rid of in hole, forms a through hole, and some product hole walls are relatively thin, and larger deformation can be produced in punch process,
There are drift side, Kong Huixiang contracts, even if cannot also avoid this thin-wall part using the punch structure of various reduction punching power
Deformation.
The content of the invention
Thin-walled deformation is eliminated during it is an object of the invention to the thin-walled punching forgings for needing punching, it is ensured that the size essence in hole
Degree, designs a kind of mould for preventing thin-wall hole punching forgings from deforming, and can apply constraint to hole wall in punch process, prevents
Deformed in punch process, while being designed with the material-pulling device to forging, prevent punch process mesopore from shrinking and forging bag occur
Firmly drift and situation about cannot come off, this drift can be used alone, it is also possible to be applied to various cooperation trimmings, punching and correction
The composite die of technique.Concrete technical scheme is as follows：
One kind forging multipart punch, including lower mould and drift corresponding with lower mould, the drift include punch-holder shank, punch-holder shank
Upper end be fixed by screws on upper padding plate；The lower end of the punch-holder shank sets cutting blade, and the cutting blade is bolted on
The lower end of punch-holder shank；External diameter of the external diameter of punch-holder shank less than cutting blade；Loose plug is socketed on punch-holder shank, the upper end of loose plug
Abutted with the spring being set on punch-holder shank, the upper end of spring abuts with upper padding plate；The lateral profile of the loose plug and forging
The side profile correspondence of part endoporus.
To face directly, bottom is inclined-plane to the outer upper of the loose plug, and it is transition face to face directly between inclined-plane, described to face directly
With angle >=3 ° of transition face.
Thickness >=the 4mm of the cutting blade.
The height on the inclined-plane for forging hole depth 2/1 to three/3rds between.
It is an advantage of the invention that：Due to the setting of loose plug, it is ensured that be first loose plug and forging during punching
Endoporus sidewall contact, is supported, it is ensured that larger deformation will not be produced in punch process to endoporus side wall in advance, additionally,
In drift lifting process, due to the effect of spring, loose plug has certain pressure to forging, it is to avoid shrinks and occurs in hole
The situation that forging encases drift and cannot come off.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the enlarged drawing of cutting blade part.
Specific embodiment
Illustrate the present invention below in conjunction with the accompanying drawings, as illustrated, the present invention include lower mould 8 and with the corresponding punching of lower mould 8
First 2, the drift includes punch-holder shank 9, and the upper end of punch-holder shank 9 is fixed on upper padding plate 6 by screw 5；Under the punch-holder shank 9
End sets cutting blade 10, and the cutting blade 10 is fixed on the lower end of punch-holder shank 9 by bolt 3；The external diameter of punch-holder shank 9 is less than cutting blade 10
External diameter；Loose plug 1 is socketed on punch-holder shank 9, and the upper end of loose plug 1 abuts with the spring 4 being set on punch-holder shank 9, bullet
The upper end of spring 4 abuts with upper padding plate 6；The lateral profile of the loose plug 1 is corresponding with the side profile of the endoporus of forging 7.
Do not influenceed by forging hole size error with the activity of forging endoporus for ease of loose plug 1, the activity
To face directly, bottom is inclined-plane to the outer upper of insert, and it is transition face to face directly between inclined-plane, it is described face directly with the angle of transition face >=
3 °, the structure can ensure that loose plug smoothly inserts forging endoporus or departs from forging endoporus.
1 >=the 4mm of thickness h of the cutting blade.
The height h on the inclined-plane for forging hole depth H 2/1 to three/3rds between.
Operating principle of the invention is：1) forging 7 is put into lower mould 8, upper padding plate 6 drives the effect in press ram
Lower drive drift is moved downward, the inclined-plane of loose plug 1 first with the contacts side surfaces of forging endoporus, under the action of the spring, by
Then inclined-plane, therefore, radial pressure can be applied to the endoporus side wall of forging, on the other hand, on the inside of the profile on inclined-plane and workpiece
Side profile correspondence, it is ensured that forging endoporus side will not deform；Continue to move downward in drift 2 and the endoporus of forging 7 is connected
After skin carries out shearing punching except action, drift 2 is moved upwards by bottom dead centre, now, because loose plug 1 is socketed on punch-holder shank 9,
Under the action of the spring, the inclined-plane of loose plug 1 still keeps contacting with the endoporus side of forging, it is to avoid shrinks and forging occurs in hole
The situation that encase drift and cannot come off.
