Definitions

  • the invention relates to a method for pulling straight elongated material prismatic cross-section with full or hollow cross-section to reduce the cross-section in at least two drawing stages, at least the second drawing stage being carried out on a drawing device with intermittently operating, linearly moving drawing slide, and a system for carrying out this method .
  • the drawing material is rolled up with a radius suitable for the drawing material and, after complete application, is transported to the next drawing machine as a whole package of materials, whereupon the known and already described drawing process is repeated there for the next reduction in cross-section after threading, etc.
  • this intermediate drum of the material to be drawn or at least with as few intermediate drums of the material to be drawn and to pass the drawn material directly from the drawing machine to the drawing machine.
  • this is not possible with such straight drawing machines because - as just described, the drawing machine works in intermittent mode during the drawing in, thus forcing the material to be stopped, while the preceding drawing machine is in the middle of the work flow, i.e. forcing a continuous material transport.
  • the invention is based on the object of proposing a method of the type described at the outset with which it is possible to connect straight-pulling machines in series and to avoid the intermediate drums previously required.
  • Another object of the invention is to propose a system suitable for carrying out the method.
  • the solution to the first-mentioned object is seen according to the invention in that, in a method according to the preamble of claim 1, the drawing material is deflected from the straight line by a drawing device with intermittently operating, linearly moving drawing slide, insofar as this is not the first drawing device, as soon as the drawing device has taken over the beginning of the drawing material
  • This deflection of the drawing material from the straight line creates a buffer area for the movement of the drawing material, so that the preceding drawing machine, which works in the continuous drawing process, can transport the drawing material undisturbed into the resulting sheet, while the following drawing machine can take over the incoming drawing material in intermittent operation during the start of drawing.
  • the further object underlying the invention for creating a system suitable for carrying out the method is achieved in that, in the case of a system according to the preamble of claim 2, viewed in the working direction, at least the second pulling device is one for pulling straight with intermittently operating, linearly moving pulling slides and a pulling nozzle arranged stationary with the pulling device, at least two pulling devices of the system being connected to one another by means of a guide device for introducing the material to be pulled into the pulling nozzle of the subsequent machine, and the guide device being means has from the straight direction of flow to the deflection of the drawn material to less than 360 0th
  • the intermediate arrangement of the guiding device enables a drawing device adjacent to a preceding drawing device to be connected directly to the preceding drawing device, so that the drawn material can be passed on from machine to machine with this guiding device and it is in the guiding device for the necessary deflection of the material the straight flow direction is provided, whereby the necessary bow for buffering the drawn material is produced.
  • the resulting bow is automatically enlarged. Only an enlargement can also be considered, because the drawing material is ejected faster from the preceding drawing device during the intermittent operation of the second drawing device than can be taken over by the second drawing device.
  • the guide device has a guide element and a deformation element, at least the deformation element being movably guided to carry out the deformation.
  • the guide element ensures the straight line execution, while the deformation element ensures the deflection from the straight flow direction.
  • the functions of “guidance” and “deflection” can thus advantageously be separated.
  • the straight design is maintained as long as necessary and then, if necessary, the deformation is initiated by the independent deformation element.
  • a V-shaped channel connects the outlet of a first machine with the input of a second machine as a guide element, the channel having an interruption in at least one point in its longitudinal course and that a transverse to the course of the Channel through which interruption movable deformation element is provided.
  • the V-shaped guide trough is a particularly simple guide element with a sufficiently safe function. It is easy to interrupt its longitudinal course without any loss of function, so that a deformation element which can be moved through this area can be provided in this area for deflecting the drawn material from the straight flow direction. It is particularly advantageous here if this deformation element is provided approximately in the middle of the distance between the two drawing machines. As a result, the force to be applied by the deformation element to the drawn material for the deformation can be kept small and a uniform deflection is achieved, seen on both sides in the direction of flow.
  • the V-shaped channel is arranged to be movable in order to terminate the straight guidance of the drawn material before the deformation is initiated.
  • This simple means enables the radial plane in which the deformation is to be carried out to be selected independently of the angular position of the V-shaped channel. It then does not necessarily have to lie the radial deformation plane so that the drawing material is lifted out of the V-shaped groove by the deformation process, but rather the V-shaped groove can be so movable that it evades the deforming drawing material.
  • a supplementary embodiment of the invention provides that the gutter is lowered. This is an easy to design direction of movement of the channel.
  • the trough is arranged to be pivotable about an axis parallel to its course. This possibility of movement is also simple to design and allows the trough to evade the desired direction of deformation of the material to be drawn.
  • a deflection slide is provided as the deformation element, which can be guided radially against the drawn material.
  • a deflection slide can also be designed and moved easily and can be guided non-positively and thus under constant desired preload radially against the drawn material. In this way, a safe deflection of the material to be drawn is effected and, at the same time, the fact that the deflection slide only lies non-positively on the material to be drawn makes it easy to track both enlargements and reductions in the deflection curve of the material to be drawn with the deflection slide.
  • the deflection slide has a carrier connected to an actuating device and at least one contact element for acting on the drawn material.
  • This is also a particularly simple structure and it is possible to separate the elements which exert the movement and the force from the elements which come directly into contact with the drawing material, so that the latter can be adapted to the particular requirements of the drawing material in question, without at the same time all other assemblies or components would have to be changed.
  • At least one contact element is designed as a body that is rotationally symmetrical about at least one axis and perpendicular to the tangent to the at least this axis Point of contact of the drawing material and the contact element is rotatably arranged on the carrier.
  • This can be one or more rollers or wheels, whereby on the one hand the bending radius of the drawing material can be influenced in a simple manner and on the other hand the axial movement is not impeded by unnecessarily large friction.
  • an adverse influence on the surface fibers of the drawn material can be avoided.
  • a fluid-operated piston-cylinder unit is provided as the actuating device. This is the easiest way to achieve a positive connection of the components that cause the drawing material to deflect from the straight line.
  • the guide device has counter-holding pieces in the area of the exit of a preceding machine and in the area of the entrance of a subsequent machine.
  • the corresponding guide elements on the machines which are arranged in the area of the exit and the entrance are relieved and it a smooth transition arch to the deflection arch, which also relieves the drawn material, can be created.
  • the guide device is designed as a circular guide, which takes over the drawing material running out of a first machine in the tangential direction and, after a deflection along a circular arc shape, introduces it tangentially into the subsequent machine.
  • this device it is possible to arrange successive machines parallel to one another, so that an adaptation to the available spatial conditions is made possible at low cost. This is particularly advantageous if the deflection takes place along an arc of a circle - around approx. 180 °.
  • the deflection along an arc of a circle by approx. 180 ° is a particularly advantageous buffering because almost any speed differences between the two machines can be absorbed only by moving the arc further apart or closer by 160 ° as a whole from the two parallel machines The arch itself can remain unchanged.
  • the guide device essentially consists of a central bearing, on which a boom is arranged so as to be pivotable about a vertical axis, the free end of the boom having a gripping device, suitable for taking over and transferring the drawing material, whereby two drawing machines to be connected to one another are arranged in such a way that their output or input lies in the effective range of the gripping device of the boom.
  • the desired deflection and thus the required buffer zone can be generated with relatively simple means.
  • the drawing machines are set up with a working direction running parallel to one another and that the guide device connecting them deflects the drawing material by approximately 180 °.
  • the boom can be driven in rotation via an associated drive.
  • This is not necessary for drawn material with a larger cross-section.
  • the boom itself which is centrally mounted and could also be designed as a wheel, for example, can then be driven by the working movement of the drawing material. With drawn material of smaller cross section, this leads to difficulties because the drawn material then buckles at undesired points.
  • the drive of the boom which must rotate the boom synchronously with the speed of the drawing material, therefore ensures that the buckling is prevented at undesired locations on the drawing material with a smaller cross-section.
  • FIG. 1 shows a system in which two drawing machines 1 are linked to one another by means of a guide device 2.
  • the working direction of the system assembled in this way is indicated by arrow 23.
  • the drawn material 7 is thus transported in the direction of arrow 23.
  • the drawn material 7 is processed, for example, in a first drawing stage by the drawing machine 1 arranged to the left of the guide device 2 in a straight-line drawing process and exits in a straight-line direction at the exit 12 of this drawing machine.
  • a bed 35 of the guide device 2 carries, aligned in the straight direction of the outflowing drawing material 7, a V-shaped channel 30 which, open at the top, is supported there.
  • an angle of 90 ° is chosen as the angle between the two legs of the channel.
  • the drawn material 7 can flow straight through this V-shaped channel and is guided by this channel straight ahead and threaded into the input 13 of the drawing machine 1 arranged on the right in the system.
  • Angel is provided, which passes through the drawing nozzle 29, so that the drawing material 7 can first be taken over by the drawing carriage 22 on this conventional fishing rod.
  • the drawing carriage 22 must first follow up on the drawing material in several steps already described at the outset of the prior art, so that during the follow-up a complete standstill of the drawing material occurs in the right drawing machine 1.
  • the left-hand drawing machine of this system according to FIG. 1 continues to operate continuously, and so there would be no special measures for buckling and destruction of both the drawing material 7 and, as a result, at least the downstream drawing machine.
  • the guide device 2 eliminates this problem.
  • an interruption 31 is provided in the course of the V-shaped channel 30 approximately in the central region of the distance between the outlet 12 of the left machine and the inlet 13 of the right drawing machine.
  • the bed 35 has a cantilever 36 on which a deformation element 21 is arranged.
  • This deformation element 21 is displaceable on the upper bed level in the radial direction of the drawn material and can for example assume a position which is shown in broken lines in FIG. 1. If the deformation element 21 is displaced radially, the drawing material 7 is thereby correspondingly deformed, that is to say deflected from its straight direction.
  • the V-shaped channel 30 can be pivoted about an axis 32 (FIG. 2), so that the V-shaped channel 30, which is intended as a guide, is no longer an obstacle to deflection of the drawing material 7 the deformation element 21 moved radially against the drawing material 7 with the necessary force.
  • This force can be generated, for example, by a fluid-actuated piston-cylinder unit 19 (FIG. 2), which moves the deformation element 21 with the appropriate force in the direction of arrow 37 and vice versa.
  • the force of the piston-cylinder unit 19 is dimensioned in such a way that, although it causes deflection of the drawing material, the drawing process itself is not adversely affected by this.
  • the piston-cylinder unit 19 is connected to a pump unit 38 or the tank 42 via the lines 40 and 41 and via the valve 39.
  • the piston-cylinder unit 19 is supplied with pressure medium by means of the pump unit 38 via the line 40, which ensures that the piston rod of the piston-cylinder unit extends and therefore a movement of the deformation element 21 in the direction of arrow 37 takes place because the piston rod of the piston-cylinder unit 19 is connected to the deformation element 21 in the manner shown in FIG. 2 or in another suitable manner.
  • the cylinder of the piston-cylinder unit is preferably supported on the bed 35 of the guide device 2.
  • the fluid displaced from the cylinder space on the piston rod side of the piston-cylinder unit 19 travels via the line 41 and again through the valve 39 into the tank 42.
  • a controllable counterpressure valve 43 can ensure that the piston of the piston-cylinder Unit 19 remains hydraulically clamped.
  • a movement of the piston rod of the piston-cylinder unit 19 in the opposite direction is achieved in that the valve 39 is moved into the second switching position.
  • counter-holding pieces 17 and 18 can be provided in the areas mentioned, which have a specific and desired contour force the drawing material 7 in this area.
  • the entire system 24 can also be equipped with a device 44 which checks the size of the radial deformation of the drawing material 7 and emits a corresponding signal. This makes it possible to regulate the working speeds of the drawing machines 1 of the system 24 as a function of the size of the radial deflection of the drawing material in such a way that an undisturbed material flow is always ensured.
  • the movements of the tappet 45 in the radial direction are measured by an electronic displacement sensor 47, for example in the form of a commercially available linear displacement sensor, the impulses of the displacement sensor 47 being forwarded to a computer 48 , which in turn forwards its calculation results to a suitable display device 49.
  • the display device 49 can also be omitted and instead the values of the computer 48 of a control device suitable for this purpose are used to coordinate the working speeds of the drawing machines of a system. Since the structure of a control loop is fundamentally known, there is no need to go into this in detail.
  • the system 24 shows a functional interlinking of two pulling devices, of which at least the pulling device lying on the right in the working direction is one for pulling straight
  • FIG. 1 Systems as shown in FIG. 1 can be: coupled several times in succession, so that a system 25 according to FIG. 6 is created.
  • the system 25 according to FIG. 6 it is also entirely possible to use guide devices 2 according to FIG. 1.

  • Such a guide device 3 is shown more clearly in FIG. 3.
  • FIG. 3 shows a system of the structure according to FIG. 1, but with the modified guide device 3.
  • a support 33 can be displaced as a deformation element 20, in a manner similar to the deformation element 21, in the direction of arrow 55.
  • On the support 33 there are contact elements 34 along a circular line attached in the form of rotatable rollers. In the middle region, two rollers 34 are provided in an opposing arrangement, between which the drawing material 7 is passed.
  • position I of carrier 33 marks the starting position and position 11 of carrier 33 the permissible end position.
  • the counter-holding pieces 51 and 52 arranged on the bed 50 fulfill the same function as the counter-holding pieces 17 and 18 according to FIG. 1. However, the counter-holding pieces 51 and 52, as elements for guiding the drawing material 7, have roles which are not specified in a similar arrangement to that Rollers 34 which are arranged on the carrier 33.
  • rollers 34 arranged on the carrier 33 could also be replaced by a wheel 53 (marked with a dashed line) which would be rotatably mounted on a correspondingly enlarged carrier 33 about the axis 54 (marked with a dashed line).
  • the entire guide device 3 described for FIG. 3 can also be constructed in the same way as the guide device 2 according to FIG. 1. It is therefore based on the detailed description, for example, of the V-shaped channel 30 according to FIG. 1, which is also provided for a guide device according to FIG can, waives. The same applies to the possible pivoting position of the bed 50.
  • a guide device has the advantage that all guide elements for the drawing material 7 carry out a rolling movement, so that friction between the drawing material and the corresponding guide elements can be largely prevented.
  • FIGS. 4 and 5 Another structure of a guide device is represented by the guide device 4 according to FIGS. 4 and 5.
