Definitions

  • the present invention relates to a device for drawing or to stretch ferrous or non-ferrous metals as wire, bar, tube or non-cylindrical profile by applying very high pressures in front of the working cone of the wire drawing process (7) of FIG. 2, thus creating an anti-wear film, thanks to selected lubricants.
  • Metal drawing and drawing conditions tribological are such that the factories are faced with anticipated wear and tear on the supply chains, therefore budgets important, to anticipated wear of the Metallization, capstans, to excessive consumption of wire drawing soap, to creation of surface defects on the wires with all their unfortunate consequences for the final product. in addition lead the manufacturer to reduce by 30 to 50% the speed of machines, this, by force of circumstances, with the loss of consecutive productivity.
  • the device according to the invention makes it possible to remedy, quantitatively and qualitatively to all these disadvantages inherent in the Trades supra.
  • Threaded or not there are 3 dimensional models of tubes for be able to cover the whole range of wire diameters to be drawn.
  • the part (3) is a square of 60X60m / m of steel (XC48) welded on the flanges of the casting machine after a meticulous alignment.
  • the tube (1) of great thickness and high hardness, is terminated by a mirror-polished cone (8) which fits perfectly into the mirror-polished cone made of Tungsten carbide or other material of the die (11).
  • the tightening under high pressure is done by the threaded sleeve of (2) which is fitted with a hexagon nut (10); a flat (9) allows the tube to be held during its plating in the cone of the die.
  • the cylindrical dies (11), according to the European ISO model, are housed in a very thick metal ring (12), which itself is introduced into the die holder (13).
  • the lubricant, greases or oils of high viscosity or lubricant powder flows into (5) by means of a translucent funnel adjusted to the diameter of the hole.
  • the ring (14) allows to receive a die / guide with a diameter greater than 20 / 100 m / m to that of the diameter of the wire (18).
  • the wire with its speed and its roughness causes lubricant "extreme pressure" in the cramped corridor (6) to (4) and thus plays the role a real compressor piston.
  • Zone 4 benefits from a lamellar flow, of the hydrodynamic type which has the consequence of bending the metal before the point of impact on the carbide track or other material .
  • the "drawing ring" on the tungsten carbide cone or other disappears and with it, the anticipated deterioration of the die, the "drawing ring” is a halo on the cone (8) of tungsten carbide due to the impact of metal arriving at high speed, generally soiled on its skin with metal particles of an earlier origin, and also due to the strong pressures to which the carbide track is subjected (8).
  • This phenomenon anticipates death of the sector; it has always been known in the trade, but real solutions have not been provided; the device according to the invention acts on this precise point, and visceral for the wire drawing.
  • the device according to the invention thus makes it possible to do away with the “Rumblege” operation, which is expensive and tedious for the manufacturer.
  • the film (15) of high compactness and of lamellar structure, repeated several times will play a real anti-wear role; it constitutes the first device objective according to the invention so that the drawing machines can rotate at the speeds provided by the Manufacturers.
  • the device according to the invention is particularly intended to create a zone (7) in FIG. 2 of very high pressures on a lubricant extreme pressure, of lamellar structure with strong anisotropy, non-limiting title, thus creating a hydrodynamic regime remarkable.
  • the tube (1) acts as pre-die by "preparing" the final work of the die / grader.
  • Figure 7 shows a more simplified variant of the Device according to the invention of Figure 1:
  • a ring (12) made of non-ferrous or ferrous metal has 2 threaded holes (25), diametrically opposite, each receiving a screw (24) which presses the tube (1) by resting on a notch (9) which has been made in this tube; the tube (1) is conical according to the same criteria mentioned above on the preceding pages; it can be terminated, on the die side, either by a mirror-polished cone, according to the criteria defined above, or by a polished flat part which is applied vigorously against the die (11); at the entrance to this tube, a housing is provided, during its design, to receive a welded, brazed or other core (14) of tungsten carbide or other material; this core will play the role of : guide die and laminating lubricant die to use the principle of FIG.
  • the screws are, without limitation, hardened steel of hardness 42/60 HRC having a fine thread for power resistant to high clamping pressures, plating the tube (1) against the die ( 11).
  • the thick frusto-conical ring (12) will, as an indication, be made of high-strength bronze or hardened steel of hardness 48/60 HRC to save the duration of the threading.
  • the ring (12) can receive 2, (see 3) dies (11) and (23) thus allowing to optimize the reduction of section in a single operation.
  • the device according to the invention with its 2 variants, inexpensive, can easily be adapted to all kinds of casting machines, benches and multipasses.
  • the device according to the invention is particularly intended for creating a film of residual lubricant, highly compacted, intended to perfect the tribological conditions during the shaping by the customers whose permanent concern is: the wear of their tools.
  • the device According to a second variant of the invention, in the case of Wet Wire Drawing, all metals combined, the device will be mounted in a "enclosing" tube represented by FIG.
  • the die 11, the non-threaded tube 16, the die 14 are all closed in a tube 19 of great thickness threaded at one end supporting a nut 20 of large caliber;
  • the die 14 has a core / wire gap of 0 to a few hundredths of m / m, with a value of 5 to 10 1 / 100 'of m / m, as an indication; taking into account the film of lubricant which is "rolled” on the wire to increase its wettability, the velocities of the kinetic energies of the lubricant "crushed" on the wire by the roller clamp 21 being located just upstream from the "rolling machine”"; the device according to the invention creates a lubricant anti-return system; note that the quantity of this which passes through the air gap is 3 to 4 times greater than the quantity of the wire / flier interface film; this film undergoes a high degree of compacification thanks to the triple congested phenomenon of: exiguity of the air gap of the die (
  • the materials of the dies will be of a hardness greater than 1500 HV by targeting 3500/4000 HV as an indication and not limiting; the polishing of the working cone will be 5/100 of Ra approximately and the working angle, commonly called 2 ⁇ will be 6 to 25 ° with an indicative value of 8 °.
  • Liquid lubricants or pasty will preferably consist of molecules of large size, strong anisotropy, which have good resistance to strong Shear stresses and mechanical "aging" and thermal: either polymers, long chain copolymers, soaps soluble doped or not, waxes, paraffins, silicones, given without limitation.
  • Page 7 gives, without limitation, a range of diameters inside the tubes which can be either cylindrical or preferably conical with an angle of 1.5 ° given as indicative, of unlimited length.
  • the device according to the invention Due to its Tribological Objectives of the implementation of Metals in the form of Long Products, by drawing or drawing operation, the device according to the invention with its 2 main targets: Dry Way and Wet Way , all products and all shades combined, is really intended to honor the fundamental objectives of the aforementioned profession, namely: the productivity of the machines by applying the speeds designed by the Manufacturer, the reduction in the "Sector Budget", the Quality of the surface condition of the work hardened products, the Longevity of metallization of capstans and control of the costs of drawing lubricants.
