The drawing machine in this case comprises a pair of drawing tool holders, the pair of drawing tool holders comprising at least a first drawing tool holder and at least a second drawing tool holder, and the first drawing tool holder being mounted in a self-aligning manner with respect to the common drawing path, the second drawing tool holder being fixed at an adjusted angle with respect to the common drawing path.

Description

  • The invention relates to a drawing machine for the continuous drawing of Drawn goods, in particular rod-shaped and tubular drawn goods made of metal, with at least two drivable, a common drawing line assigned drawing tools, and with a drawing tool holder pair, wherein the pair of drawing tool holders has at least a first one Drawing tool holder and at least one second drawing tool holder and the first drawing tool holder self-aligning to the common one Drawing line is stored.
  • When continuously pulling drawn material, for example made of metal, with Pulling machines, especially with chain pulling machines, are made possible by a Drawing tool to be drawn on a drawing line between Clamping jaws clamped, the clamping jaws by means of endless, drive chains driven by chain wheels are moved in the pulling direction. To support the contact pressure, the drawing tools run along one Drawing tool holder, the contact pressure from the drawing tools the drawing tool holder are transferred. The contact forces arise among other things, in which the drawing material along the drawing line of the parallel opposing drawing tools is clamped, whereby the drawing tools engage on both sides of the drawing section with the drawing material are located. The contact forces introduced into the drawing tool holder are made by storing the drawing tool holders in one Machine frame of the drawing machine initiated.
  • Such a drawing machine with the previously described Drawing tool holders are known and are in the patent application US 3,945,547. Here are both drawing tool holders of a pair of drawing tool holders each in a bearing stored. The drawing tool holders are here by means of separate Adjustment devices aligned to each other. The adjustment devices are fixed to the machine frame of the drawing machine so that the Adjustment device Setting forces on the corresponding drawing tool holder can exercise.
  • The invention is based on the object of a drawing machine develop further, so that on the one hand a simplified setting of the two Drawing tool brackets to each other and the other Contact forces can be distributed more favorably over the drawing section.
  • The object of the invention is achieved by a drawing machine for continuous drawing of drawn material, in particular bar and tubular metal drawing material, with at least two drivable, one common drawing line assigned drawing tools, and with one A pair of drawing tool holders, the pair of drawing tool holders at least one first drawing tool holder and at least a second Drawing tool holder includes. The first drawing tool holder is self-centering stored to the common drawing line, the second Drawing tool holder at an adjusted angle to the common Drawing line is fixed. The second is according to the invention Drawing tool holder, especially during drawing, opposite the common one Draw line fixed at a certain angle. This can advantageously Angles can be set before pulling so that the pulling machine is optimal can be adjusted to different drawn goods.
  • A drawing tool holder is understood to be a component of the Drawing machine with which a drive chain of the drawing machine among other things is guided along the drawing line.
  • A particularly simple embodiment provides that the second Drawing tool holder has at least two bearings. By means of this The second drawing tool holder can have at least two bearing points compared to the common drawing line in a particularly simple way in be fixed at a set angle. The fixation can on the other hand also be realized via other, non-rotating bearings, such as by flat storage areas.
  • It is advantageous if the pair of drawing tool holders, in particular the first drawing tool holder opposite the second drawing tool holder is freely swinging. This is the first drawing tool holder self-aligning with the second drawing tool holder of the Pulling tool holder pair, creating a separate alignment as well a separate alignment device for the drawing tool holders Pulling tool holder pair is omitted. Even components such as the Pulling tool holders can adjust or align against each other possibly omitted in the drawing machine according to the invention, so that not just the alignment process of conventional tool holder to each other or to the drawn material is eliminated, but also adjustment work on the There are no facilities. The bearings are, for example Eccentric shafts, which are arranged in the drawing machine frame, realized. Due to the oscillating arrangement of the first drawing tool holder to the second drawing tool holder is advantageously the first Drawing tool holder automatically opposite the second Drawing tool holder.
  • At least one bearing of the pair of drawing tools can be one Have plain bearings. Plain bearings have the advantage that they are very are low-maintenance, have good damping properties and have relatively high forces be able to record.
  • To ensure safe storage, at least one Bearing of the pair of drawing tools have a rolling bearing.
  • A preferred embodiment provides that a bearing of the first Drawing tool holder spaced from a connecting line between two bearings of the second drawing tool holder and between the two bearing points of the second drawing tool holder is arranged. Preferably, the two drawing tool holders can Drawing material to be drawn using the three-point bearing of the pair of drawing tool holders bend in such a way that the contact pressure on the Drawing tools or on the drawing tool holder along the drawing line advantageous be distributed. The possibility of bending creates a uniform contact pressure in the area of the drawing line. For example arise in the respective drawing tool holders of the Drawing tool holder pair significantly less force peaks, so that the Service life of the drawing tools or the drawing machine is increased.
  • The term "connecting line" here denotes a straight line between two functionally identical points of two bearing points.
  • In order to apply the contact pressure symmetrically via the drawing tool holders distribute, it is advantageous if the bearing of the first Drawing tool holder centered on a longitudinal axis of the first drawing tool holder is arranged.
  • On the other hand, it is proposed that the depository be the first Drawing tool holder eccentric on a longitudinal axis of the first Drawing tool holder can be arranged. Due to the eccentricity of the bearing with regard to the first drawing tool holder, the moments which by pulling the material to be drawn onto the drawing tools, advantageous be compensated.
  • In the present context, the term "longitudinal axis" denotes one line parallel to the direction of drawing by the corresponding line Drawing tool holder. The term "eccentricity" refers to an eccentric Arrangement of the storage or bearings of the first Drawing tool with respect to the bearings of the second drawing tool holder. For example, the bearing point of the first drawing tool is two Bearing points of the second drawing tool are not arranged centrally.
  • Another embodiment provides that the connecting line two Bearing positions of the second drawing tool holder with respect to their angle the drawing line is fixed.
  • To further reduce the construction effort, it is advantageous if the Bearing positions of the second drawing tool holder on the Machine frame of the drawing machine are arranged. The construction effort reduced with regard to the bearings of the second drawing tool holder among other things by the fact that from an adjustment mechanism the bearing points can be disregarded.
  • So that a distance between the two opposite Drawing tool holders of the pair of drawing tool holders can be varied it is advantageous if the bearing of the first drawing tool holder slidable to the connecting line of the two bearing points of the second Drawing tool holder is. The possibility of setting the distance with regard to the two drawing tool holders is for example for differently drawn semi-finished products necessary, as well as around the beginning of a new semi-finished product with a corresponding device by Lead drawing machine.
  • Other objects, advantages, and characteristics of the present invention will become apparent explained with reference to the description of the accompanying drawing, in which a pair of drawing tool holders is shown as an example.
  • It shows
  • Fig. 1 shows a schematic longitudinal section through a chain pulling machine and
  • Fig. 2 is a schematic side view of a storage in a frame of the chain pulling machine.
  • The drawing machine 1 cut longitudinally in the figure has a first drawing tool holder 2 and a second drawing tool holder 3 . Both drawing tool holders 2 and 3 each have an endlessly revolving frame. The drive chain 4 and 5 converge at the height of a central axis 8 such that they convey a drawing good in the direction of arrow 9 - here from left to right - through the drawing machine 1 . The central axis 8 simultaneously marks the position of a drawing plane, in which the drawing material is preferably moved during the drawing process. The plane of the drawing runs perpendicular to the paper plane of the drawing.
  • The first drawing tool holder 2 is mounted with a single bearing 10 in the housing (not shown here) of the drawing machine 1 . This enables the first drawing tool holder 2 to level off freely relative to the drawing plane described above. As a result, no further adjustment devices are required to align the drawing tool holder in accordance with the drawing plane.
  • The bearing point 10 is designed as a plain bearing and is arranged in the middle of a longitudinal axis of the first drawing tool holder 2 .
  • The first drawing tool holder 2 can be freely leveled around the bearing 10 in the direction of arrow 11 with respect to the second drawing tool holder 3 .
  • The second drawing tool holder 3 is mounted with two bearings 12 and 13 in the drawing machine 1 . The bearings 12 and 13 are fixed to one another via an adjusting device.
  • The fact that the bearing point 10 of the first drawing tool holder 2 is arranged between the two bearing points 12 and 13 of the drawing tool holder 3 , among other things due to the bearing geometry according to the invention, the contact forces occurring during a drawing process are distributed particularly advantageously uniformly, in particular in the region of a drawing section between the two drawing tool holders 2 and 3 . As a result, force peaks, in particular in the drawing tool holders 2 and 3, are better compensated for.
  • In order to vary the distance between the opposing drawing tools 6 and 7 in the region of the central axis 8 , the first drawing tool holder 2 can additionally be displaced in an arrow direction 14 by means of the bearing point 10 .
  • FIG. 2 shows how the bearing points 10 , 12 and 13 of the drawing machine 1 are operatively connected to one another in order to mount the two drawing tool holders in an adjustable manner. The three bearing points 10 , 12 and 13 are each mounted on a frame 15 and are each activated by an adjusting rod 16 , 17 and 18 . It goes without saying that the adjusting rods 16 , 17 and 18 can be replaced by any technical means which implement an interaction of the bearing points 10 , 12 and 13 with one another.
  • The actual displacement of the drawing tool holders 1 , 2 is due to an eccentricity of the bearing points 10 , 12 and 13 on corresponding pivot bearings 19 , 20 and 21 , on which the adjusting rods 16 , 17 and 18 act and via which the bearing points 10 , 12 and 13 on the Frame 15 are stored, realized. The rotational positions 19 , 20 and 21 can for example be designed as roller bearings or plain bearings.
  • If the bearing point 10 is set by a cylinder 22 of the drawing machine 1 , the bearing point 10 acts on the bearing point 13 by means of the adjusting rod 17 such that the bearing point 13 is also set. The bearing point 13 is in turn connected to the bearing point 12 by means of the adjusting rod 18 in such a way that an adjustment of the bearing point 13 also brings about an adjustment of the bearing point 12 . Due to the selected arrangement of the adjusting rod 17 at the bearing points 10 and 13 , the bearing point 13 adjusts in relation to the bearing point 10 , the bearing points 12 and 13 being adjusted identically by the type of attachment of the adjusting rod 18 to the two bearing points 12 and 13 .
