Definitions

  • the invention relates to the field of metallurgy and relates to the application of lubricants to metal material which 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 in the invention.
  • wires, profiles or pipes can be processed as forming material.
  • Lubricants used to create an order on the drawn material Solid lubricants are mainly processed in powder form.
  • the drawing material is provided with a carrier layer, for example a phosphate layer, before pulling, or the drawing material surface is roughened.
  • a carrier layer for example a phosphate layer
  • To apply the lubricant it is already known, among other things, to guide the drawing material before entering the drawing die through a box in which there is a solid lubricant.
  • the drawn material runs through lubricating pollen within the lubricant, which press the lubricant in the solid state onto the drawn material.
  • the above-mentioned method of applying the order from solid or semi-greasy lubricants has a number of significant 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 shear rollers do not produce a better lubricant application, but rather wipe the lubricant off the drawn material.
  • the leader adhering to the known method disruptions in the supply of lubricant to the drawing die and thereby poor surface quality of the formed drawing stock, cold welding between the drawing stock and drawing die, excessive drawing forces and low possible decreases and drawing speeds.
  • the aim of the invention is to create conditions for reducing the effort and for improving the quality when applying solid or semi-solid lubricants and for increasing the work productivity and product quality when forming metallic materials.
  • the invention is based on the object of designing the application of solid or semi-solid lubricants to metallic materials which are intended for cold forming in such a way that even on such material which is not provided with a carrier layer there is a firmly adhering, homogeneous, uninterrupted lubricant application. is guaranteed.
  • This object is achieved according to the invention with a method in which the material to be formed is transplanted through one or more consecutively arranged coating layers in which a lubricant which is liquefied as a result of pressure and / or heat, but which is solid or solid at room temperature, is applied to the material to be formed becomes.
  • the lubricant is expediently introduced into the first coating chamber together with the material to be formed, and then also partially fed to the subsequent coating chambers via cannulas.
  • the material to be formed in the coating chamber is first passed through a zone in which the lubricant is pulverized in a fluidized bed or is continuously injected and is brought to the non-forming groove by electrostatic charging known per se, the material to be formed then running through a conical nozzle , in which an at least partial liquefaction of the applied lubricant is carried out due to the build-up of pressure and the development of heat due to the continuous material to be formed.
  • the material to be removed can then be passed through the calibration chamber outside the coating chamber to produce a lubricant film of defined thickness.
  • the material to be formed can be heated in or in front of the vortex zone.
  • the invention includes a device which consists of a heatable coating chamber and an associated charging and bridging device for the lubricant, the coating chamber receiving or containing the liquefied lubricant and an inlet and outlet nozzle for the passage of the Has formed goods.
  • the inlet nozzle is expedient Adjusted cross-sectional dimensions of the material to be formed.
  • the opening of the outlet nozzle is advantageously tapered in the direction of flow and has a at its narrowest point the cross-sectional dimensions of the material to be formed plus the allowance for the desired lubricant film thickness.
  • Both nozzles are extended by means of a heatable or coolable approach.
  • the approaches are each connected to the pressure chamber via a heat accumulation section.
  • a variant of the execution according to the invention is that there are several working drawing bricks arranged in or one behind the other in a housing, a pressure chamber serving to liquefy the lubricant being arranged in front of each working drawing brick and a pressure ring being arranged on the outlet side of the device in the housing for re-coating the drawn material and this is connected to the pressure room, or in the case of several working dies, to the pressure rooms, via channels.
  • the pressure ring connects to the working die arranged in front of it, forming a pressure chamber, the channels opening into the pressure chamber.
  • This pressure chamber can have a conical inlet with a final cylindrical guide part, the diameter of the guide part being adapted to the desired lubricant film thickness.
  • the channels between the pressure spaces can be formed by grooves made in the device parts. The number, cross-section and / or arrangement of the channels are designed in accordance with an automatic pressure regulation or pressure adjustment. In order to be able to liquefy a solidified lubricant in the device in the event of work interruptions, the device is designed to be heatable.
  • the invention allows the distribution of solid lubricants due to their high dynamic viscosity for pulling high-strength materials for the pulling of higher strength works open thing can be combined with the distributions of liquid or semi-solid lubricants, which ensure a homogeneous lubricant application.
  • the application according to the invention is in the case of continuous multi-stage pulling
  • the layer of lubricant on the formed material ensures a stable drawing condition and the resulting distributions.
  • the application of the lubricant which was carried out using the working dies according to the invention, at the same time permits very effective forming, in particular in the case of multiple pulling and in the case of pressure drawing tools with several working dies.
  • the invention enables forming with hydrodynamic lubrication and guarantees high forming speeds and degrees, especially when using solid lubricants with high dynamic viscosity.
  • a coating operator 1 is connected via a lubricant supply line 2 to a charging and pressure generating device 3, which feeds a lubricant 4 into the piston by means of hydraulically operated compressor pistons, not shown in the drawing NO CHECKING PRESS.
  • the coating chamber 1 is provided with a heating jacket 5, so that the solid lubricant 4 unuer the Einvirirang ven brück and heat liquefied.
  • the liquefied lubricant 4 transports the material to be formed 6, which is fed into the reporting device 1 through an inlet nozzle 7 and out through an outlet nozzle 8.
  • the inlet nozzle 7 is concerned with the cross-sectional dimensions of the molded material 6 in such a way that no lubricant escapes 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 dimensions for the desired lubricant wheel 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. In order to ensure that the lugs 9 function adequately, they are connected to the heated coating chamber 1 via a heat accumulation section 11.
  • Liquefied calcium starch at a temperature of 150 ° C. and a pressure of 10 at is located in the coating chamber 1 as the lubricant 4.
  • the material to be formed 6 emerging from the device has a firmly adhering, homogeneous and continuous lubricant film.
  • Be the device shown in Figure 2 are in a housing consisting of a steel body 12, an adapter sleeve 13 and a pressure nut 14, an inlet ring 15, two working dies 16; 17 and a pressure ring 18 arranged in a row.
