Definitions
- the present invention relates to a straight-ahead drawing machine for drawn material, in particular rods, tubes or profiles, with at least two drawing carriages which can be driven on a track, with each drawing carriage being assigned a route.
- the invention further relates to a method for continuously pulling drawn material straight by means of a straight-ahead drawing machine with at least two drawing carriages, the drawing material being drawn on a track by means of at least one drawing carriage along a travel route assigned to the drawing carriage.
- a first drawing carriage runs on a track and behind it a second drawing carriage, each of which is provided with clamping jaws. While one car is pulling, the other is running back to its starting position at high speed. When the pulling power is transferred from one car to the other, both cars are controlled synchronously. Because of this and because of the relatively long length of the clamping jaws, which grasp the material softly, a drop in the drawing speed is avoided when the drawing force is transferred from one carriage to the other.
- the disadvantage of the drawing system described in the cited document is that the individual drawing cars are assigned unchangeable routes.
- this has the consequence that the drawing material is continuously introduced into the drawing machine is not possible or is possible only with great difficulty. So that a continuous introduction of the drawing goods into the drawing machine is possible, the first drawing car must grip the drawing goods so far away from the end of the drawing goods that the drawing goods, when the first drawing car has reached the end of its travel distance, so far into the travel distance of the second Pulling car protrudes that the second pulling car can pick up the goods and move on.
- the invention is therefore based on the object of proposing a straight-ahead drawing machine and a method for operating a straight-ahead drawing machine, with which a continuous introduction of the drawing material into a straight-ahead drawing machine is possible simply and quickly.
- the routes that are assigned to the drawing car can be set variably. Due to the possibility that the travel distances of the individual drawing wagons can be variably determined, the drawing wagons can be controlled or regulated in such a way that the drawing wagons for introducing the drawing material into the drawing machine are brought as close as possible to the drawing nozzle around the drawing material introduced into the machine through the drawing nozzle take. A further pushing in or pulling by hand becomes unnecessary and there is then no need for insertion and follow-up in a first cycle by the first pulling carriage.
- the routes of the individual drawing cars can, for example, be set so that they overlap.
- the routes of the drawing car can be changed in particular during the operation of the straight-ahead drawing machine.
- the straight-ahead drawing machine preferably has a regulation or control for determining the routes.
- the drawing carriages can be driven with an electric linear motor. It is advantageous if the web has the inductor and the drawing car has the armature of the linear motors. In order to enable operation of the linear motor according to the principle of a synchronous motor, the drawing carriages can also carry excitation coils.
- the inductor advantageously has coils arranged along and / or on the track.
- the straight-ahead drawing machine can have a control or regulation via which a current flow through the individual coils can be controlled or regulated independently of one another, as a result of which the routes of the individual drawing cars can be controlled or regulated.
- the coils of the inductor can be switched on independently of one another by the control, or by the regulation, so that there is a traveling field for each drawing car through which the drawing car is driven. Because the regulation, or control, which specifies traveling fields, the route of the individual drawing wagons can also be determined by means of the regulation or regulation. A constructive intervention in the drawing machine or a modification in the drawing machine is not necessary for this. Rather, the travel routes can be determined during the operation of the drawing machine by the specifications for the control or regulation. According to the invention, the drawing carriages can be guided mechanically or electromagnetically on the track.
- the coils of the drawing machine (coils of the inductor, excitation coils, coils for electromagnetic guidance) can be superconducting.
- the power of the linear motor can be increased to such an extent that pulling speeds are possible which are significantly higher than the pulling speeds previously achieved.
- Such an increase in performance is already possible when using a linear motor without superconducting coils compared to the current drawing machines with conventional electric motors.
- the object is further achieved according to the invention in that, in the case of a method for continuously pulling drawn material straight, the route of the drawing car is changed during the drawing.
- the travel routes can be defined such that the travel routes overlap.
- the end of the drawing material can be transferred from the first drawing car to the second drawing car in the overlap area.
- the first drawing car can pull the drawing goods previously taken up in the area of a drawing nozzle to the beginning of the overlap area, while there the second drawing car picks up the end of the drawing goods and pulls the drawing goods to the end of the overlap area with the first drawing car, where the first drawing car releases the drawing material.
- the second drawing car can then pull the drawing goods to the end of the route of the second drawing car according to the invention after taking over the drawing goods from the first drawing car.
- the travel distance of the first drawing carriage and / or the second drawing carriage can be changed according to the invention for the following cycles after the drawing goods have been released by the drawing carriage.
- the travel distances of the drawing cars cannot overlap in the following cycles.
- the straight-ahead drawing machine can have more than two drawing carriages, in each case two drawing carriages which are not immediately adjacent being moved synchronously with one another on the web in order to pull the drawing goods through the machine. Through the synchronous switching of two or more drawing cars, the pulling force of the drawing machine can be multiplied, so that higher target performance can be achieved.
- FIG. 1 is a side view of a straight-ahead drawing machine at the beginning of the introduction of the drawing material (first cycle),
- FIG. 2 shows the straight-ahead drawing machine according to FIG. 1 during the first cycle, but at a later state of insertion
- FIGS. 1 and 2 shows the straight-ahead drawing machine according to FIGS. 1 and 2 during the first cycle after the transfer of the drawing goods to the second drawing car
- Fig. 4 shows the straight-ahead drawing machine according to Figures 1 and 3 in a cycle after insertion
- Fig. 5 is a speed-time diagram of the first and second pull car during a cycle.

- a drawing material is drawn from a larger cross-section to a smaller cross-section through this drawing nozzle.
- the drawing machine has a first drawing carriage 4 and a second drawing carriage 5, which are guided on a rod 6.
- the drawing carriages 5 and 6 are provided with clamping jaws 7, with which the drawing carriages grip the drawing goods 3 and pull them through the drawing nozzle 3.
- the drawing car 4 and 5 also have an iron plate 8, which forms the armature of a linear motor.
- the linear motor is completed by coils 9, which form the inductor of the linear motor.
- the coils 9 are connected to power supply lines 10 via a control, or control unit (not shown) connected to a power supply unit.

- the drawing carriages 4, 5 are controlled such that they run synchronously at the same drawing speed when the drawing goods 3 are transferred from one drawing carriage to the other.
- This phase of the transfer from the first drawing carriage 4 to the second drawing carriage 5 is denoted in FIG. 5 by the reference symbols 22/23.
- the drawing material is held by the jaws 7 in both drawing cars for a short period of time.
- the jaws 7 of the first drawing carriage 4 release the drawing material, which moves back at high speed, while the continuous drawing is carried out by the second drawing carriage 5.
- the diagram of the first drawing carriage 4 is fully distinguished, while the diagram of the second drawing carriage 23 is shown in dashed lines.
- 22a and 23a show the phases in which the drawing carriages pull the material to be drawn through the drawing machine.
- the phases of the transfer of the drawing goods from the first to the second drawing car are designated 22/23.
- 22b shows the phase of the return trip of the first drawing carriage 4 from the end of the route 1 1 to the beginning 1 1 a of the route 1 1.
- 22b shows the return trip of the second drawing carriage 5 from the end 12b to the beginning 12a of the route 12.
- the inclined flanks of the diagram represent phases of acceleration or deceleration.
- the coils 9 of the inductor are controlled in such a way that two non-overlapping, directly abutting routes 1 1, 12 result for the drawing cars 4 and 5.
- the coils 9 of the inductor are activated in such a way that the travel distances 11, 12 of the drawing carriages 4, 5 overlap.
- the hiking fields are also limited to the individual routes 11, 12 here, they can also “walk in” in the area of the route of the other drawing car.
- the routes are determined by the route not shown Control unit that switches the coils 9 of the inductor on or off in such a way that the desired traveling field for driving the drawing carriages 4, 5 is created.
- the drawing carriages 4, 5 are located at the beginning 1 1 a, 12 a of their routes 1 1, 12.
