Definitions
- the invention relates to the field of metallurgy and relates to a method and an apparatus for coating and Forming of strand-like metallic material to be formed by drawing using lubricants in solid to liquid Status.
- a method and an apparatus for applying are known solid or semi-solid lubricants for cold forming metallic materials, in which the material to be formed into a closed chamber is introduced, in which one under the Exposure to pressure and / or temperature liquefied There is lubricant (DD 147 209).
- the chamber is as heatable Pressure chamber executed and with a loading and Pressure generating device for the lubricant connected.
- For the passage of the material to be coated has Pressure chamber an inlet and an outlet nozzle.
- a lubricant pressure is generated hydrostatically.
- the wire passes through these devices before entering the Drawing die a pressure chamber in which there is a liquid Lubricant.
- the lubricant pressure is controlled by a pump generated.
- the seal is on the inlet side of the pressure chamber another drawing die used as a sealing nozzle (J. Schiermeyer, Dissertation TU Clausthal 1979; US 3,413,832).
- the structure of the device should be in the main drawing nozzle hydrodynamic lubrication conditions are generated.
- Drawing die upstream of a more or less long inlet part either a tube, a profiled funnel or a Drawing die can be (L. Gogecki, T. Prajsnar, wire trade journal 1972, 12, pp. 768-771; J. Schiermeyer, thesis TU Clausthal 1979).
- the inside diameter of the inlet part is slightly larger than the diameter of the incoming Wire.
- Such devices are called hydrodynamic Called pressure nozzles.
- the increased lubricant pressure is hereby automatically by the moving and lubricant transporting wire generated (hydrodynamic pressure build-up). This results in very high lubricant pressures of around 300 MPa generated. This procedure has the disadvantage that as a result of high pressures of the lubricant out of control from the tools is pushed out and often also damage or even the tools are destroyed.
- a disadvantage of this procedure is that the external generation of high lubricant pressure with a very high equipment costs, and that on the other hand in this device, too, lubricant is often uncontrolled emerges from the inlet nozzle against the direction of drawing, especially when the lubricant changes into the paste-like Status. Leakage of the lubricant is especially then the case when pulling wire rod, which is often out of round and / or if the device is in the range of high lubricant pressures is working.
- the invention is based, based on the task aforementioned generic state of the art a method and device for coating and forming strand-like to develop metallic metal by pulling with which high-performance forming with significantly reduced apparatus expenditure is possible, while the Sealing problems eliminated and one or more technological Parameters in the forming and coating process depending on respective material to be further improved.
- This task is accomplished with a coating and coating process Forming of strand-like metallic material by means of Pull, in which the material to be formed in a double chamber arrangement, the from a low-pressure lubricant chamber and one on it subsequent lubricant high-pressure chamber, with Lubricant is coated and formed, being in the Lubricant high pressure chamber through this in this chamber incoming material with lubricant High pressure lubricant is generated, according to the invention solved that the lubricant low pressure chamber lubricants in solid to paste-like state by means of an external Lubricant supply are supplied and by means of this Lubricant supply to the lubricant in the low-pressure lubricant chamber a low pressure is applied.
- Another one Characteristic is that the forming by means of one each Output of the low-pressure lubricant chamber and the high-pressure lubricant chamber located working die becomes.
- the high pressure lubricant is in the high pressure lubricant chamber over the arriving there, with fixed to liquid lubricant coated material to be formed, wherein in such a lubricant pressure-lubricant temperature combination is set that the Lubricant in this chamber in the solid to liquid state is present.
- lubricant pressure in the high pressure lubricant chamber by changing the forming and Process parameters affect how especially by changing the lubricant pressure and the Lubricant temperature in the low-pressure lubricant chamber, the Drawing speed, drawing die geometry and degree of deformation.
- the Thickness of the lubricant film measured on the formed material and / or the lubricant pressure in at least one of the Pressure chambers measured.
- the measured values obtained become Control or regulation of the pulling speed, the Lubricant pressure and / or the lubricant temperature used.
- the lubricant low pressure chamber is useful with the help an extruder and / or a gear pump continuously and filled with lubricant through only one feed opening. It is advantageous with these devices at the same time the required lubricant pressure in the Lubricant low pressure chamber created.
- a high-pressure lubricant chamber is used Lubricant pressure regulated from 80 MPa to 500 MPa.
- Lubricant pressure is a lubricant pressure in the range of 0.2 MPa up to a maximum of half the value in the lubricant high-pressure chamber generated lubricant pressure generated.
- the process can also be carried out several times in a one-step process can be applied in a multi-stage process. It is useful after an interruption in the forming process, a brief one Reversal of the between formed material and double chamber arrangement during to carry out the existing relative movement of the forming process and / or the pressure existing in the lubricant chambers lower.
- the invention includes a Device which contains a double chamber arrangement which consists of a low pressure lubricant chamber and one on it subsequent lubricant high-pressure chamber with which the material to be formed is coated and formed, the Lubricant high pressure chamber in the outlet with one Working die is equipped.
- the device is characterized in that the lubricant low pressure chamber one inlet nozzle and one in the outlet Has working die, which is also the inlet nozzle for forms the connected high-pressure lubricant chamber.
- a lubricant feeder for feeding solid to pasty lubricant and to produce a Lubricant pressure in the low-pressure lubricant chamber connected.
- a Device for measuring the thickness of the formed Formed lubricant film and / or at least one of the pressure chambers is a sensor for the Lubricant pressure can be arranged, the measured value outputs with Devices for controlling or regulating the Pulling speed, lubricant pressure and / or Lubricant temperature are connected.
- the Lubricant low pressure chamber an extruder and / or Gear pump for supplying the lubricant and generating the Lubricant pressure connected.
- the double chamber arrangement can be used to control the Temperature and pressure conditions with cooling devices and / or heating.
- a major advantage results from the surprising Wise effect of a relatively large lubricant mass flow from the low pressure chamber to the high pressure chamber simultaneous reshaping with that between the chambers arranged working die.
- the large lubricant mass flow is the basis for the construction of the high pressure chamber desired high lubricant pressure.
- the double chamber system according to the invention also allows in the low pressure lubricant chamber with such low Lubricant pressures to work that even for this chamber significant sealing problems occur even if the in lubricant in the chamber in a paste-like state is present.
- the device shown is with a double chamber arrangement constructed, through which the material to be formed 1 in the with Arrows marked direction is pulled through.
- the Dual chamber assembly contains a low pressure lubricant chamber 2 and one downstream in the direction of pull Lubricant high pressure chamber 3.
- the lubricant low pressure chamber 2 is at its entrance for that Formed material 1 equipped with an inlet nozzle 4, the Nozzle diameter is 0.1 mm larger than the diameter of the incoming material 1.
- a working die 5 for forming the the forming material 1 leaving the low-pressure lubricant chamber 2 arranged, which is also the entrance to the lubricant high-pressure chamber 3 forms.
- the lubricant low pressure chamber 2 is with a Lubricant feed 7 for feeding solid to paste-like Lubricant 8 connected.
- the lubricant supply 7 consists of an extruder. With this one is in the chamber Lubricant pressure generated in the range of about 40 MPa.
- Lubricant 8 can, for example, be solid lubricant Calcium stearate base can be used.
