Abstract
The present invention discloses a special mold sleeve for a cold drawing mold. The special mold sleeve is characterized by comprising an inner cabin 1 for placing a cold drawing mold, an outlet hole 2, and a stop step 3, wherein the shape of the special mold sleeve is processed into a conical shape, the inclined angle is 5-80 DEG so as to easily be corresponding to the cold drawing machine mold hole size, the inner diameter phi2 of the inner cabin is about 1-1.5 mm slightly larger than the outer diameter of the cold drawing mold, the width D2 is equal to the width of the cold drawing mold, the hole size phi3 of the outlet hole is between the outer diameter of the cold drawing mold and the cold drawing machine mold hole so as to achieve smooth pulling-out of a seamless steel pipe, the stop step is provided for preventing the cold drawing mold from axial movement during applying of force on the cold drawing mold, and the height D3 is designed into the half of (phi2- phi3). The special mold sleeve has beneficial effects of substantial saving of particularly valuable tungsten steel, reduction of production cost and reduction of superhard mold material processing difficulty.
Description
Technical field
The present invention relates to solid drawn tube technical field, be specifically related to the special-purpose die sleeve of a kind of cold drawing die.
Background technology
Cold-drawn is the topmost production method of seamless steel pipe.Cold-drawn production process is: particular manufacturing craft is placed in the control of drawbench mould, by brute force, is drawn seamless steel pipe is extracted in mould, thereby obtain needed section configuration and specification.The drawbench of certain tonnage, its nib is certain, and as T15 drawbench, its mold hole dimension is ￠ 300mm, and wide 80 mm, are horn-like cone.And T15 drawbench, processing solid drawn tube external diameter scope is generally from ￠ 10mm to ￠ 80mm, and this just means that, from 10 plurality of specifications moulds in ￠ 10mm-￠ 80mm, its appearance and size must all be processed by drawbench nib ￠ 300mm, wide 80 mm.Cold drawing die is the frock of most critical in seamless steel tube production, because be consumable accessory, scrappage is high, and mould amount of purchase is large.Cold drawing die is manufactured by wolfram steel, and price is very expensive, and per kilogram reaches 600 yuan of left and right, and mould consuming cost often will account for 10% left and right of seamless steel tube production cost.A large amount of small dimension cold drawing dies, also to unify nib ￠ 300mm, wide 80 mm processing profiles by drawbench, not only cause the significant wastage of mold materials and remaining high of production cost, and because must correspondence be processed into cone, also increased the difficulty of processing of cold drawing die.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of special-purpose die sleeve of cold drawing die matching with drawbench nib, to reach the free-revving engine of significantly saving valuable wolfram steel, reduce production costs and reduce superhard mold materials difficulty of processing.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Cold drawing die increases the positive cylinder of 10～20mm outer ring again by its actual outside diameter, remainder is replaced by special-purpose die sleeve, the minimized cold drawing die of appearance and size is arranged in the special-purpose die sleeve matching with drawbench nib, and special-purpose die sleeve is arranged in drawbench nib.
The special-purpose die sleeve of described a kind of cold drawing die, mainly comprises and puts cabin 1 in cold drawing die, outlet opening 2, prevention step 3, its sharp processing bevel 5-8
0taper shape so that and drawbench nib corresponding.
As the special-purpose die sleeve of the further improved a kind of cold drawing die of the present invention, it is characterized in that: put cabin internal diameter ￠ 2 in cold drawing die and be slightly larger than cold-drawn external mold external diameter 1～1.5 mm left and right, interior cabin width D 2 equals cold drawing die width.
As the special-purpose die sleeve of the further improved a kind of cold drawing die of the present invention, it is characterized in that: described outlet opening aperture ￠ 3, between cold drawing die external diameter and drawbench nib, is convenient to seamless steel pipe and is extracted smoothly.
As the special-purpose die sleeve of the further improved a kind of cold drawing die of the present invention, it is characterized in that: described prevention step, its objective is while stoping cold drawing die stressed and move axially, its height D3 is designed to half left and right of (￠ 2-￠ 3).
The present invention adopts after such structure, means with the special-purpose die sleeve of the very cheap Q235 smooth bar of material cost, has replaced the major part of the cold drawing die outer shroud that the past manufactured by wolfram steel, has directly reduced mould purchase cost approximately 50%.And die shape is simplified to present right cylindrical by the circular cone in past, this,, for superhard wolfram steel material, effectively reduces difficulty of processing and processing cost.
Accompanying drawing explanation
Below the expressed content of this Figure of description 1 and the mark in figure are briefly described:
In accompanying drawing 1: 1 for putting cabin in cold drawing die, and its internal diameter is ￠ 2, width is that D2,2 is outlet opening, and aperture ￠ 3,3 is for stoping step, and width is D3, is highly half of (￠ 2-￠ 3).
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with accompanying drawing 1 and embodiment, the present invention is described in further detail, this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the special-purpose die sleeve of a kind of cold drawing die, coning, maximum outside diameter ￠ 1 is slightly less than drawbench nib import internal diameter in configuration design, and gradient is 5-8
0, be convenient to corresponding drawbench mold hole dimension.
The special-purpose die sleeve of described a kind of cold drawing die, the interior cabin of its work is used for the special cold-drawn external mold of putting, and its internal diameter ￠ 2 is slightly larger than cold drawing die external diameter 1～1.5 mm left and right, makes the interior degree of tightness of cold drawing die storing die sleeve suitable, and its width D 2 equals cold drawing die width.
The special-purpose die sleeve of described a kind of cold drawing die, designs oral pore, and its aperture ￠ 3, between cold drawing die external diameter and drawbench nib, is convenient to seamless steel pipe and is extracted smoothly.
The special-purpose die sleeve of described a kind of cold drawing die, design stops step, its objective is while stoping cold drawing die stressed and moves axially, and its height D3 is designed to half of (￠ 2-￠ 3).
First the special-purpose die sleeve of cold drawing die being arranged on to drawbench unifies in nib, cold drawing die is placed in special-purpose die sleeve in cabin again, after solid drawn tube is pricked head, pierces into after cold drawing die, drawbench clamp is clamped seamless steel tube binding head part, extract smoothly, complete a Cold Drawing Process.
