Definitions

  • the invention relates to a method for lubricating forming and primary forming tools, of molds for pressure, automatic and continuous casting and briquetting, especially for the lubrication of hot forging tools.
  • the invention relates to a device for performing the invention Process.
  • Forming and primary forming tools are known to be lubricated to them on the one hand to cool them, but on the other hand to prevent them from becoming excessive Protect wear and make it easier to shape the workpiece.
  • Lubrication with carbon in particular with carbon black and graphite, is known Form of suspensions and pastes, but these substances are often included other substances are mixed (cf. EP 0 403 306 A1; EP 0 507 449 A1; EP 0 590 959 A2 and US 5,468,401).
  • Lubrication of tools with graphite in the form of suspensions and Paste has the disadvantage that the lubricant does not usually adhere there, where it is most needed, especially on edges and vertical or for Forming direction approximately vertical and inclined surfaces. This is where drips the lubricant or cannot be applied at all.
  • Another disadvantage consists in the considerably unclean work and the pollution of the workplace and thus the environment, so that such lubricants are not in all Have cases and apply to all forming processes, especially in some countries have relatively high requirements for the use of lubricants on forming tools gives the workers handling the health damage to preserve, but also to protect the environment.
  • the invention is based on the object, a method for lubrication of forming and master forming tools of the required type to improve that with low environmental impact otherwise difficult to access or tool surfaces that are difficult to lubricate, such as edge areas surfaces that run almost vertically or at an angle are well and permanently lubricated can be used with careful and thus effective use of the Lubricant.
  • the invention has for its object a device for To carry out the method according to the invention.
  • the powder can be fluidized according to claim 16 by vibrations or by introducing gas, for example by compressed air.
  • the device according to the invention is of relatively simple construction, since only for this purpose a spray gun, a container for the powder to be sprayed and charged or powder batch and a hose line and optionally an electrical one Cables need to be used. Such devices are suitable therefore also under rough operating conditions, as for example in Hot forging prevail to be used.
  • the compressed air line is used to convey the carrier air (claim 18).
  • the spray device in particular a spray gun, can also be assigned to a manipulator, which can program the individual contours or surfaces of the relevant tool, for example a forging tool, after program control (claim 19).
  • Claim 21 describes a particularly advantageous embodiment of the invention.
  • the fluidization device can be designed as a vibration device and / or as a compressed air device which introduces air brought under pressure into the powdered lubricant in order to loosen it up and thereby make it more transportable.
  • the spray gun is encapsulated to suit the forge - claim 22. This protects it particularly well against flying sparks, but also against impact and shock loads and thermal stress.
  • the amount of lubricant can be changed during the forming process or forging process, for example increased or decreased.
  • the lubricant is also arranged on vertical contours and edge areas.
  • Reference numeral 1 denotes a spray device designed as a spray gun, who manipulated in a suitable way, for example back and forth, but also moved up and down, or otherwise manipulated in a spatial manner can be. For example, it is possible to manually close this device handle, or a manipulator, not shown, which is preferably program-controlled is to assign.
  • the double arrow under the spray gun 1 should generally indicate the mobility of the spray gun 1.
  • Reference number 2 denotes a powder container in which a suitable one Lubricant in powder form, for example a mixture of different powder components, for example made of graphite and electrically chargeable components or z. B. only made of graphite.
  • a suitable one Lubricant in powder form for example a mixture of different powder components, for example made of graphite and electrically chargeable components or z. B. only made of graphite.
  • the individual Store components in various containers not shown and only before or in the spray gun 1 during the conveying process mix and there electrostatically by high voltage coils, not shown charge.
  • the rest of the electrical charging device with electrical or electronic components is usually assigned to the spray gun 1 and is not shown. It can consist of electrical lines, controls, electronic Components, for example strong electromagnets, coils and the like, consist.
  • On the powder container 2 is a conveyor hose 3 for below Pressure gas, in particular compressed air and powder, indicated.
  • Reference numeral 4 designates a supply hose for purging gas, in particular for purge air. This supply hose 4 is on the one hand to the powder container 2 on the other connected to the spray gun 1.
  • FIG. 5 shows a compressed gas line, in particular a compressed air line, due to the pressurized gas, especially compressed air, the powder container 2 is supplied.
  • Suitable control and regulation devices and a Pressurized gas source, e.g. B. a compressor are for simplification also not shown.
  • An electrical line designed as a mains connection bears the reference symbol 6, through the electrical energy for the appropriate motors, but also for the electrical charging, etc., is introduced.
  • 7 denotes a line, via which a control signal for the spray gun 1 can be forwarded, while 8 represents an electrical connection for the spray gun 1.
  • a band generator over which, for example, a voltage of 30,000 volts and high-voltage cascades, For example, 70000 volts are available for reasons of Simplification also not shown.
  • the tools 9 and 10 which can be designed as hot forging tools, with a High voltage source to be charged and coated with powder.
  • the tool is connected to the positive pole while the Spray gun 1 negatively charges the powdered lubricant to be sprayed and over the ionized air on the surfaces of the tools to be sprayed 9 and 10 sprayed on. This will reduce the proportion of spray material sprayed too much considerably reduced, which is possible due to oppositely charged electrodes is.
  • the surfaces to be lubricated can also be added be wetted beforehand with water or the like to avoid spraying with powder To facilitate lubrication.
