Definitions

  • the invention relates to a device of the type specified in claim 1.
  • the metal forming material is intended for cold forming, for example for drawing with hydrodynamic lubrication.
  • Lubricants that are solid or semi-solid at room temperature, such as calcium stearate, soft soap or beeswax, can be used.
  • wires, profiles or pipes can be processed as forming material.
  • Solid, semi-solid and liquid lubricants or lubricants are used for cold forming of metallic materials by drawing, with which an order is generated on the drawn material.
  • Solid lubricants are mainly processed in powder form.
  • the drawn material is covered with a backing layer, e.g. a phosphate layer or the surface of the drawing material is roughened.
  • a backing layer e.g. a phosphate layer or the surface of the drawing material is roughened.
  • the known method of applying the order from solid or semi-solid lubricants has some major shortcomings.
  • the application of the carrier layers mentioned or the roughening of the surface of the drawing material is very complex.
  • a sufficiently homogeneous lubricant coating is not guaranteed for solid, powdery lubricants, even with existing carrier layers.
  • the lubricating rollers stop or there is a difference between their peripheral speed and the wire speed, the lubricating rollers cause the lubricant to be wiped off the drawn material.
  • the defects inherent in the known method lead to malfunctions in the supply of lubricant to the drawing die and thus to a poor surface quality of the formed drawing stock, to cold welding between the drawing stock and drawing die, to high drawing forces and to low possible decreases and drawing speeds.
  • the invention is based on the prior art given in FR-A-1139790.
  • the lubricant liquefied under external pressure is applied to the material to be formed.
  • the material to be formed leaves the coating room with a film of lubricant that has a liquid consistency until the immediately following forming process.
  • the liquid lubricant wipes off almost completely in the first drawing die, so that additional drawing strips require new coatings.
  • the invention is based on the object of designing a device of the type specified in such a way that a firmly adhering, homogeneous, uninterrupted lubricant layer is ensured which permits several subsequent cold forming operations.
  • Embodiments of the invention result from the dependent subclaims 2 to 4.
  • the invention makes it possible to combine the advantages of solid lubricants, which can also be used for drawing higher-strength materials due to their high dynamic viscosity, with the advantages of liquid or semi-solid lubricants, which ensure a homogeneous application of lubricant.
  • the application according to the invention can be used in continuous multi-stage drawing processes.
  • the homogeneous lubricant layer applied to the material to be formed ensures stable drawing conditions and the resulting advantages.
  • the application of the lubricant provided according to the invention using the working dies allows at the same time a very effective reshaping, in particular in the case of multiple pulling and in pressure-drawing tools with several working dies.
  • a closed container in the form of a coating chamber 1 is connected via a lubricant supply line 2 to a charging and pressure generating device 3, which presses a lubricant 4 into the coating chamber 1 by means of hydraulically operated compressor pistons (not shown).
  • the coating chamber 1 is provided with a heating jacket 5, so that the originally solid lubricant 4 liquefies under the action of pressure and heat.
  • the liquefied lubricant 4 transports the material to be formed 6, which is introduced into the coating chamber 1 through an inlet nozzle 7 and out through an outlet nozzle 8.
  • the inlet nozzle 7 is dimensioned according to the cross-sectional dimensions of the material to be formed 6 in such a way that no lubricant emerges from the nozzle.
  • the opening of the outlet nozzle 8 is funnel-shaped and has the cross-sectional dimensions of the material to be formed 6 at the narrowest point, plus the oversize for the desired lubricant film thickness.
  • Both nozzles 7; 8 are each extended by an approach 9. These approaches 9 can be heated or cooled by means of coils 10. Depending on whether the lugs 9 are cooled or heated, the lubricant is present in the batch in solid or liquid form, as a result of which the lugs can be used as a valve. To ensure adequate functioning of the lugs 9, they are connected to the heated coating chamber 1 via a heat accumulation section 11. As a lubricant Material 4 is in the coating chamber 1 liquefied calcium stearate at a temperature of 150 ° C and a pressure of 10 at. The material to be formed 6 emerging from the device has a firmly adhering, homogeneous and continuous lubricant film.
  • an inlet ring 15, two working dies 16; are in a housing consisting of a steel body 12, an adapter sleeve 13 and a pressure nut 14; 17 and a pressure ring 18 arranged in a row.
  • the pressure chambers are connected to one another via channels 22.
  • the pressure chamber 21 present between the last working die 17 and the pressure ring 18 opens into a conical inlet 23 and this into a cylindrical guide part 24.
  • a material to be formed 25 is drawn through the device in the form of a wire, which has a solid lubricant made of calcium stearate.
  • the lubricant entering the first pressure chamber 19 is liquefied therein and partly automatically via the channels 22 to the other pressure chambers 20; 21 fed.
  • the inlet ring 15 has the task of guiding the lubricant in the direction of the channels 22 and preventing the lubricant from flowing back out of the first pressure chamber 19.
  • the lubricant is used for forming by the second working die 17, and in the third pressure chamber 21 it serves to coat the material 25 to be formed.
  • the cylindrical guide part 24 places the thickness of the lubricant film on the outgoing wire 25 for forming in further downstream drawing stages firmly.
