Description
Technical field
The invention belongs to manufacture the domain variability of tubular metal thing to be related to shaping jig, particularly possessing improves wearing for durability
Hole top, forging drift and plug.
Background technology
Seamless steel pipe generally goes through three thermoforming stage productions.During the first stage, about 1200 DEG C of steel billet position is heated to
In on Mannesmann piercing mill, by interior shaping jig --- perforating head, it is processed to hollow ingot.Wherein oblique roller rolling transports steel billet
Move to pass through perforating head.During second stage, hollow ingot is in longitudinal operation of rolling in interior shaping jig --- plug it is auxiliary
Help down, diameter and wall thickness are reduced and length increase.During the phase III, rolled piece be processed to needed for length and wall thickness, typically not
Using interior shaping jig.
The interior shaping jig used during the first second stage is subjected to high temperature and high machinery pressure in process of production.Therefore it is many
Shaping jig uses heat-resisting steel making in the case of number.Interior shaping is inevitably produced when being rolled for a long time in production process
The progressively heating of instrument.The intensity of instrument reduces and can not bear mechanical load after heated.Instrument is deformed and damaged in itself.
In order to improve service life, perforating head uses natural oxidizing layer.The oxide layer reduces workpiece and conducted to instrument
Heat simultaneously prevents being rapidly heated for instrument to be lost in quick intensity.The oxide layer is but quickly in the forming process of high alloy material
Come off and lose heat insulating function.
Plug is according to the different using instrument that is autoxidation or possessing layers of chrome of forming method.Corresponding top example can
With referring to the A1 of German patent DE 10 2,008 056988 (SMS MEER).The shortcoming of the technology is to be conducted for workpiece to instrument
Heat effect of heat insulation it is too small.So particularly at a slow speed with the interior shaping jig under the conditions of small contact length, can generate heat and become
Shape is damaged.
If the thickness of oxide layer is improved, the life-span of these instruments can also be lifted.Because effect of heat insulation is more preferable
And protective layer preserves the longer time in abrasion.
The iron oxide protective layer formed by matrix material autoxidation does not have high stability.It was not only crisp but also porous
It can thus be damaged easily under machinery and thermic load.Therefore the thickness of such protective layer is limited under 0.8 millimeter, protects
Effect is similarly limited.Heat can be penetrated into the matrix of instrument and reduce its intensity and be allowed to damage ahead of time.High alloy Workpiece shaping
When abrasion, protective layer can be made comparatively fast to be come off after by a bit of rolling stock.
Indicate that a kind of perforated for seamless pipe is pushed up in the A1 of international patent application WO 2,011 107214 (SMS MEER)
Head or plug or warm and hot forging tubular metal thing drift, it possesses oxide layer surface specific profile attached thereto.So can be real
Now more preferable adhesive force and longer service life.Surface forms groove during processing, i.e., resulting " frame " will not surmount
Top or the surface of plug.
Similar instrument, its coating is made up of molybdenum oxide, known by the A1 of patent EP 0385439 (NKK CORP.).
The A1 of european patent application EP 2404680 (SUMITOMO) theme is given birth to using the seamless steel pipe of Mannesmann's method
Production.It requires a perforating head, and its feature is that the top has a passage, can be by the passage by lubricant during perforation
Import perforation lanes.[0053] section of the patent points out that the top can add iron coating.A piece iron wire is imported into a spray
Painting instrument simultaneously is allowed to melt.The iron being melted is sprayed onto on top again, so as to form a continuous coating.
But cost is too high for the production of the instrument of this kind of surface specific profile in actual production, because each perforating head
Need finished surface specific profile, and can also cause the waste of material respectively.Production cost is with the increasing of Surface Machining depth
Plus superproportional increase.Economy and the feasibility upper limit are several millimeters.Another defect of processing matrix surface specific profile exists
Oxidizable steel is limited in material.Such steel chrome content is low therefore hardness is also low.
The present invention target therefore that, production possess improve service life hot forming tool, its do not possess it is above-mentioned lack
Fall into.Particularly compared with prior art, the hot forming tool possesses the oxide layer of higher intensity, and it is easy to apply and not had
Spillage of material.

Protective layer.
" projection " is meant, protrusion (" peak structure ") higher than tool surfaces and groove (" the paddy knot with being carved into surface
Structure ") the processing of surface specific profile it is opposite.
In addition present invention additionally comprises it is a kind of manufacture by possess at least in proportion the tool base of face coat constitute heat into
The method of type instrument, wherein
(a) a metal bump thing is added on matrix, and
(b) then the metal bump thing completely or partially aoxidizes and is converted into protective layer.
Additional projection thing processes contrast with tool surfaces.Add in the present invention without removing material.Unexpectedly
Ground finds that additional metal protrusion is not only more obvious than Surface Machining and is easier to realize, and all or part for passing through raised material
Conversion obtains the considerably higher and durable oxide layer of hardness, therefore the life-span of instrument can also significantly improve.In addition the present invention is gone back
Can be by selecting protrusion material to change the attribute and adjusting process condition of sealer.
Economic well-being of workers and staff that the present invention is brought is carried it is clear that particularly reduce tool expense during production product made from steel
High run time, it is related generally to the waste of material of bigger length of rolled piece and reduction.
