Abstract
The utility model discloses a kind of lathe punch, including fixing end and working end, the working end includes polished rod, hole flanging portion and punching portion, the punching portion, hole flanging portion and polished rod are sequentially connected setting since end, the fixing end connect setting with the polished rod, the polished rod is straight-bar, and the hole flanging portion generally cone or taper type, the polished rod are connect with the punching portion arc chord angle transition.The pre- flanging bore of product is fixed in punching portion, punching portion circular cone or taper type, so that circular hole is easier to be inserted into fixed pre- flanging bore, stress by hole flanging portion taper 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 the service life is longer for bulb punch than sprouting.
Description
Technical field
The utility model is related to steel pipe's production apparatus field, specifically a kind of lathe punch.
Background technology
Hole flanging, as by bore edges translate into erect side, it is different from punching, punching be by waste material along closed outline from
A kind of stamping procedure detached 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 hole flanging is realized by two procedures, i.e., in advance
Punching and hole flanging.
Punch, the metal parts in diel in machine tool, is called and rushes stick, red needle or punching pin, is installation
Continuous stamping punching press is carried out in diel and thrusts operation, makes machined material that separation or plastic deformation occur, 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 as A types punch, T-type punch, special-shaped plunger chip；Punching
Head is mounted in metal parts in diel, is in direct contact applied to material, so that material is deformed upon, cut material
Material；Mold and punching head generally uses high-speed steel and wolfram steel etc. to be used as material, there is high-speed steel punch and wolfram steel punch etc., and high-speed steel is
Most common material, there are commonly 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 technique productions have following defect：1, more demanding to the ball head for punching of sprouting, not such as machining on spherical end
When, will cause hole flanging damage and it is unqualified；2 and mold when assembling because punch and fixed plate are to be interference fitted to be easy to cause
Punch tilts (being more easy to occur in production process), keeps product unqualified；3, 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；4, the punch damaged is also not easy to replace.5, it takes out
The service life of bud punch is short.
Utility model content
The purpose of this utility model is to provide a kind of lathe punches, to solve the problems mentioned in the above background technology.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of lathe punch, including fixing end and working end, the working end include polished rod, hole flanging portion and punching portion, institute
It states punching portion, hole flanging portion and polished rod and is sequentially connected setting since end, the fixing end connect setting with the polished rod, described
Polished rod is straight-bar, and the hole flanging portion generally cone or taper type, the polished rod are connect 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 and circular hole is easier to be inserted into fixed pre- flanging bore,
Stress by hole flanging portion taper is gradually that material is distracted, and the small contact surface of material forced area is small, and bulb is relatively
Greatly so that product accumulates that waste material is few, and the size of flange is more stable, while ratio sprouts bulb punch service life more when flange
It is long.
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 hole flanging 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, punching portion circular cone or taper type are fixed by punching portion so that circular hole is easier
It is inserted into fixed pre- flanging bore.
The beneficial of the utility model has the technical effect that：1, processing is more prone to, yield higher；2, punch is in hole flanging
It waits, is not easy to tilt；3, hole flanging product waste material is few, hole flanging dimensionally stable；4, service life is long, and readily replaceable.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the utility model structure diagram one；
Fig. 2 is the utility model structure diagram two；
In figure：Punching portion 1, hole flanging portion 2, polished rod 3, fixing end 4.
Specific implementation mode
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality
Novel protected range.
As shown in Figs. 1-2, the utility model provides a kind of lathe punch, including fixing end 4 and working end, the working end
Including polished rod 3, hole flanging portion 2 and punching portion 1, the punching portion 1, hole flanging portion 2 and polished rod 3 are sequentially connected setting since end,
The fixing end 4 connect setting with the polished rod 3, and the polished rod 3 is straight-bar, the hole flanging portion 2 generally cone or frustum
Shape, the polished rod 3 are connect with the punching portion arc chord angle transition.The pre- flanging bore of product, 1 circular cone of punching portion are fixed by punching portion 1
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 that gradually material is supportted
It opens, 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, turns over
The size on side is more stable, while the service life is longer for bulb punch than sprouting.
Further, 4 diameter of the fixing end is more than the working end diameter.
Further, the punching portion 1 and/or the hole flanging portion 2 are equipped with one layer of wearing layer.Make 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
Easily it is inserted into fixed pre- flanging bore.
At work, punching portion 1 is inserted into the pre- flanging bore of fixed product to lathe punch, plays fixation, punch when 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.
Above-described the utility model embodiment does not constitute the restriction to scope of protection of the utility model, any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
