Background technology
The master operation of Production for Steel Wire comprises the raw material selection, removes iron scale, oven dry, coating processing, heat treatment, wire drawing, coating processing etc.
Wire drawing is under the traction of capstan winch (seeing wire drawing machine) at drawing block, and wire rod or medium line base pass through the wire drawing die bore deformation, reaches to reduce section change shape to obtain the steel wire that size, shape, performance and surface quality all meet the requirements.The drawing of steel wire will be carried out a plurality of passages usually, and passage draft (the long-pending decrement of meeting) is between 10%～40%.The mould that drawn steel wire uses mainly contains fixed die, roller die (seeing roller die drawing), rotating mould etc., and based on fixed die.Fixed die promptly is the wire drawing die that the round pie center has pass for the profile of being made by integral material, and mould maintains static in drawing process.Roller die is the mould of being made up of 2～4 rotating rollers.Roller die drawing is generally used for drawing some deformed wires and less-deformable steel silk, but is more prone to along with the improvement of the raising of roller die device rigidity, precision and adjustment become, and its scope of application is constantly being widened.The body construction of mould is identical with fixed die during the rotating mould wire drawing, but in the drawing process, it rotates around the steel wire axis under the driving of transmission mechanism.Advantage is the direction of the frictional force between steel wire and the die wall when having changed drawing, has increased the shear stress that acts on the steel wire, makes the steel wire easy deformation, thereby can reduce pulling capacity and drawing power; The inhomogeneous deformation of steel wire ectonexine reduced thereupon when the reduction axial friction made drawing; Because mould rotates at a high speed, the nib wearing and tearing become evenly, and the out-of-roundness of steel wire and surface roughness all have improvement.But steel wire easily rotates with mould even twists when using rotating mould, therefore is confined to the drawing of crin at present.Under the situation of using the fixed die drawing, apply backward pull as if entrance point and then form the counter pull drawing at steel wire; If being applied ultrasonic vibration, mould then forms ultrasonic drawing; If adopt static pressure or hydrodynamic lubrication then to be called the forced feed lubrication drawing.
The tissue of steel wire and mechanical property change in the Cold Drawing Process, produce work hardening.Along with the increase of cold deformation degree, increases such as the tensile strength of general steel wire, hardness, elastic limit, and declines such as percentage elongation, the contraction percentage of area.Owing to there is work hardening, so after the deformation extent of drawing reaches certain value, owing to the remarkable decline of steel wire cold-forming property is not suitable for continuing drawing again, need carry out intermediate heat-treatment to recover its processing characteristics, a general draft that pulls out journey is about 70%～90%.Therefore, the technological process of Production for Steel Wire has the characteristics of reciprocation cycle.As shown in Figure 1, it is as follows that existing diameter 5.5mm is drawn into the technological process of diameter 1.3mm: acid washing phosphorization, diameter 5.5mm are drawn into diameter 2.8mm, heat treatment for the first time, acid washing phosphorization, diameter 2.8mm are drawn into diameter 1.3mm for the second time.The general phosphatization pond of using about 7 tons of existing technology, free acidity is 6～8 points, total acidity is 60～80 a phosphatization liquid, about 40 minutes of processing time, need heat treatment, twice acid washing phosphorization and twice drawing, complex procedures has increased production cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of steel wire Hubbing method, simplifies working process, and reduces cost.
The present invention solves the problems of the technologies described above the technical scheme that adopts to provide a kind of steel wire Hubbing method, and in turn include the following steps: a) steel wire being immersed tonnage is 15～25, and free acidity is 10～14 points, and total acidity is 80～120 phosphatization pond; B) acid washing phosphorization is 2～3 hours; C) then to adopt diameter of cylinder be 650mm water tank wire drawing car with the steel wire one-off drawing of diameter 5.5mm to 2.8mm; D) adopt at last diameter of cylinder be 450mm water tank wire drawing car with the steel wire succeeding stretch to 1.3mm.
The present invention contrasts prior art following beneficial effect: steel wire Hubbing method provided by the invention, by adjusting phosphatization pond size and phosphoric acid concentration, adopt the big or small water tank wire drawing car of difference that the steel wire of diameter 5.5mm is drawn into diameter 1.3mm, save heat treatment and pickling for the second time, simplify working process, reduce cost.
