Definitions
- Pressure lubrication has been increasingly used in wire drawing technology in recent years. There are several principles, the best known of which are: a) generating pressure using external pumps; b) generating the pressure with the aid of a lubrication channel in which the pressure builds up as a function of the length and diameter of the tube in relation to the diameter of the wire, rod or tube to be drawn; c) Suitably shaped double or multiple drawing blocks.
- the object of the invention is to further improve these known drawing devices.
- the improvement according to the invention makes it possible to achieve increased cross-sectional reductions and / or increased drawing speeds, in particular in the case of materials which have poor drawing properties.
- the object of the invention is achieved in that the nozzle-shaped drawing channel and the lubrication channel are each arranged in a single body and the inclination of the walls of the lubrication channel to the channel axis is 2-10 °.
- the inclination is preferably 4-9 ° or 5-8 °.
- the two channels Due to the separate arrangement of the lubrication channel and the draw channel in one body, it is possible to design the two channels independently of one another and to adapt them to the tasks on which they are based. So the choice of knife, the taper and the length of the drawing channel can be set entirely to the lubricant to be used and to the desired lubricant pressure at the end of the lubricating channel. This pressure depends on the material and the drawing speed.
- the drawing channel is arranged in a separate component, it can be given the best shape for the deformation.
- the high lubricant pressures in the drawing channel that can be achieved through the conical drawing channel did not make it seem favorable to have two bodies collide in this zone because sealing difficulties were feared.
- the hydrodynamic pressure does not build up linearly, but can lead to a maximum pressure in the channel and thus in front of the drawing channel.
- the viscosity of the lubricant and the drawing speed such high pressures can be achieved that the material to be drawn is deformed before it enters the drawing die.
- the drawing tool itself then has to bring about a small deformation, so that when the deformation in the drawing die is fully utilized, a larger cross-sectional decrease is possible, namely by that which already occurs in the lubrication channel.
- This deformation in the lubrication channel is not always uniform, so that the drawing tool also has the task of calibrating the drawing material.
- the pressure that arises in the inlet duct can, with the correct choice of the angle of inclination, the inlet and outlet ducts of the duct, with the appropriate length and with appropriate selection of the viscosity of the lubricant, values up to 20,000 bar can be reached. Most of the materials used in practice are already deformed at such a pressure maximum.
- the drawing die 1 is located in the bore 2 of a tool holder 3, which is provided with an internal thread, into which a nipple 4 is screwed, which presses the drawing die 1 against a shoulder 5 of the tool holder 3.
- the nipple 4 is provided with a conical channel 6, which tapers towards the drawing die 1.
- the tool holder 3 has a king channel 7, which is covered by an annular disk 8 which is screwed to the tool holder 3. Ring seals 9 are provided for sealing.
- the coolant is supplied and discharged by means of lines 10 and 11.
- the inclination of the duct wall to the duct axis depends on the viscosity of the lubricant used and thus on the material of the goods to be drawn.
- an inclination of 4 - 5o has proven to be particularly favorable.
