Abstract
The present invention discloses a kind of lathe punch, including fixing end and working end, including fixing end and working end, the working end includes polished rod, hole flanging portion and punching portion, polished rod described in the punching portion, the hole flanging portion is sequentially connected setting since end, and the fixing end is connected setting with the polished rod, and the polished rod is straight-bar, the hole flanging portion generally cone or taper type, the polished rod are connected with the punching portion arc chord angle transition.The pre- flanging bore of product is fixed in jack portion, jack portion circular cone or taper type, so that circular hole is easier to be inserted into fixed pre- flanging bore, stress by the taper of hole flanging portion is gradually that material is distracted, the small contact surface of material forced area is small, and bulb is relatively large so that it is few that product accumulates waste material when flange, the size of flange is more stable, while longer than bulb punch service life of sprouting.
Description
Technical field
The present invention relates to steel pipe's production apparatus field, is specifically a kind of lathe punch.
Background technology
Hole flanging, as be used for by bore edges translate into erect side, it is different from punching, punching be by waste material along closed outline from
Separated a kind of stamping procedure on material or process part processing, obtains the hole of needs on material or process part processing, and hole flanging is along endoporus week
Enclose a kind of stamping procedure that material is translated into edge-on flange.In the prior art, generally realize hole flanging by two procedures, i.e., it is pre-
Punching and hole flanging.
Punch, the metal parts in stamping die in machine tool, is called and rushes rod, red needle or punching pin, is installation
Continuous stamping punching press is carried out in stamping die and thrusts operation, makes machined material that separation or plastic deformation occur, so as to obtain
Required finished product or semi-finished product.
Punch is also punch-pin, upper mold, formpiston, red needle etc., and punch is divided into A types punch, T-shaped punch, special-shaped plunger chip；Punching
Head is mounted in the metal parts in stamping die, is contacted applied to the direct of material, deforms upon material, cuts material
Material；Mold and punching head is generally used as material using high-speed steel and wolfram steel etc., there is high-speed steel punch and wolfram steel punch etc., and high-speed steel is
Most common material, common to have CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., wolfram steel material is generally used
On more demanding punching and shearing die.
In the prior art, the common mode of production is used carries out close-fitting, stationary phase with the ball-type punch to sprout and fixed plate
Hole flanging is carried out to position.Such a technique productions have following defect：1st, it is more demanding to the ball head for punching of sprouting, such as machining on spherical end not
When, will cause hole flanging damage and it is unqualified；2 and mould when assembling because punch is easy to cause with fixed plate for interference fit
Punch tilts (being more easy to occur in production process), makes product unqualified；3rd, sprout punch flange when, material and punch extruding have
Certain material falls back, the punch that sprouts product waste material is more, and hole flanging size is unstable；4th, the punch of damage is also not easy to replace.5th, take out
The service life of bud punch is short.
The content of the invention
It is an object of the invention to provide a kind of lathe punch, to solve the problems mentioned in the above background technology.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of lathe punch, including fixing end and working end, including fixing end and working end, the working end include light
Bar, hole flanging portion and punching portion, polished rod described in the punching portion, the hole flanging portion is sequentially connected setting since end, described solid
Fixed end is connected setting with the polished rod, and the polished rod is straight-bar, the hole flanging portion generally cone or taper type, the polished rod
It is connected with the punching portion arc chord angle transition.The pre- flanging bore of product, punching portion circular cone or taper type are fixed by punching portion so that
Circular hole is easier to be inserted into fixed pre- flanging bore, and the stress by the taper of hole flanging portion is gradually that material is distracted, material stress surface
The small contact surface of product is small, and bulb is relatively large so that and product accumulates that waste material is few when flange, and the size of flange is more stable,
It is longer than bulb punch service life of sprouting at the same time.
Further, the fixing end diameter is more than the working end diameter.Improve the fixing intensity of punch.
Further, the punching portion and/or the jack portion are equipped with one layer of wearing layer.So that punch service life is more
It is long.
Further, the pre- flanging bore of product, jack portion circular cone or taper type are fixed by jack portion so that circular hole is easier
The fixed pre- flanging bore of insertion.
The beneficial of the present invention has the technical effect that：1st, processing is more prone to, yield higher；2nd, punch is in hole flanging, no
Easily tilt；3rd, hole flanging product waste material is few, hole flanging dimensionally stable；4th, service life is grown, and readily replaceable.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention one；
Fig. 2 is schematic structural view of the invention two；
In figure：Punching portion 1, hole flanging portion 2, polished rod 3, fixing end 4.
Embodiment
Technical scheme is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's all other embodiments obtained without making creative work, belong to the scope of protection of the invention.
As shown in Figs. 1-2, the present invention provides a kind of lathe punch, including fixing end 4 and working end, the working end include
Polished rod 3, hole flanging portion 2 and punching portion 1, polished rod 3 described in the punching portion 1, the hole flanging portion 2 is sequentially connected since end to be set
Put, the fixing end 4 is connected setting with the polished rod, and the polished rod 3 is straight-bar, and the hole flanging portion 2 is generally conical or bores
Platform shape, the polished rod 3 are connected with the punching portion arc chord angle transition.The pre- flanging bore of product is fixed in punching portion 1, and punching portion 1 justifies
Cone or taper type so that circular hole is easier to be inserted into fixed pre- flanging bore, and the stress by 2 taper of hole flanging portion is gradually material
Distracted, the small contact surface of material forced area is small, and bulb is relatively large so that and it is few that product accumulates waste material when flange,
The size of flange is more stable, while longer than bulb punch service life of sprouting.
Further, 4 diameter of fixing end is more than the working end diameter.
Further, the punching portion and/or the punching portion 1 are equipped with one layer of wearing layer.So that punch service life
It is longer.
Further, the pre- flanging bore of product, 1 circular cone of punching portion or taper type are fixed by punching portion 1 so that circular hole more holds
The easily fixed pre- flanging bore of insertion.
At work, the pre- flanging bore of the fixed product of the insertion of punching portion 1 plays fixation to lathe punch, punch during hole flanging
It is not easy to tilt, the stress by 2 taper of hole flanging portion is gradually that material is distracted, carries out hole flanging.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention
Within enclosing.
