Abstract

The machine has two or more driven drawing chains (3,4) with drawing members (5A,B) having clamp jaws for the drawn material on one side, and a slide surface on the other side. The slide surfaces support themselves on rigid roller guides (9) on each chain, via drive rollers (8). The drive rollers are interactively supported on the slide surfaces (13) and/or the roller guide via a divided contact surface, and on the level of the surface division, only via guides (31) moving with the rollers. The rollers are combined to form a chain.

Description

The invention relates to a chain pulling machine for continuous pulling of rod-shaped and tubular drawing material in particular according to the preamble of claim 1, in particular a chain drawing machine with at least two drive chains assigned to a common drawing section, each have interconnected tension members and the side of the Tension members provided means can be driven, the tension members on one side with a clamping jaw that can be pressed onto the drawing material and on one other side are provided with a sliding surface with which the tension members via rotating, load-bearing idler rollers on each drive chain support the assigned rigid roller guide.

When continuously pulling metal drawing material with Chain drawing machines become the drawing material to be drawn by a drawing tool pinched on a drawing line between jaws, the Clamping jaws by means of endless rotating chain wheels Drive chains are moved in the direction of pull. For sliding friction free Supporting the contact forces, the drive chains run on a variety of load-bearing idler rollers, which in turn are endless around fixed tracks or circulate rigid roller guides. To pinch the drawn goods, are at least two drive chains with clamping jaws along the drawing line provided, each by means of the machine-side assigned to them Roller guides and idler rollers are supported. With two drive chains the roller guides are parallel and on both sides of the drawing line. At some drawing machines also have multiple drive chains, which then either symmetrically or asymmetrically their jaws to the Press drawn material.

EP 0 548 723 B2 shows a generic chain pulling machine. The Tension links of the drive chains have on their back, i.e. who the Side facing away from the jaws on a sliding surface that acts like a roller bearing via a moving chain guided on a fixed, rigid roller guide of idler rollers. The clamping force is achieved by means of the idler rollers directly from the clamping jaws over the sliding surfaces to the Transfer role management. To make the machine rigid to achieve and around the inclination of the idler rollers, at uneven The idler rollers are used to counteract and counteract stress arranged in the middle, with all sliding surfaces of the arranged in series Tension members a single, opposite the rigid roller guide over the same width as the idler rollers and the roller guide width have extending sliding surface. Due to the central arrangement of the Contact surface between the idler rollers and the sliding surface of the tension members or the machine-side roller guide should have an exact application of force or force distribution achieved in the machine frame and the wear of the Idlers are minimized. The individual tension members are over Bolted together and have a complicated arrangement of other idlers and locking plates, their geometric Dimensions are coordinated.

The object of the invention is to provide an improved chain pulling machine create that is simple and allows high clamping forces.

This object is achieved by the invention specified in claim 1 solved.

According to the invention it is provided that the idler rollers with the sliding surface and / or the roller guide interact via a divided contact surface and at the level of the contact surface division only by using the rollers guided guides are guided. That way one needs elaborate guide device on the sliding surface and / or the Roller guide can not be provided, which increases the presentation costs reduce significantly. Maintenance of the machine is also easier because a fixed guide or a guide running with the tension members only is very difficult to access.

It can be provided that the roller guides for the drive chains by means of at least one essentially along the drawing line extending relief recess are divided into guideways. Since the Roller guides on which the idler rollers roll with tolerances are afflicted and in particular are never completely flat, they can Idler rollers better due to the relief recess Adjust the roller guide so that the effective load-bearing line of force increases.

Preferably, the sliding surface of the is also to achieve the same advantages Tension members by means of at least one relief recess in slideways divided. It is particularly preferred if the idler rollers themselves are designed so that, based on the entire width of all Guideways and slideways are slightly flexible, so that they adhere to existing tolerances in the guideways and slideways can adjust.

In a first embodiment it is provided that the idler rollers move extend over at least two guideways, preferably thus one idler roller extends over all guideways. For Increasing the adaptability of the idler roller to existing ones Tolerances then particularly advantageously have the idler rollers each Relief recess associated with circumferential taper. The Follower wheels experience, depending on the location of the Relief cutouts, deliberate weakening or minimization of their Diameter, so that a within the width of the idler rollers elastic adjustment or elastic bend to compensate for the tolerances can take place within the guideways and sliding surfaces.

In an alternative embodiment, the idler rollers are made of parallel roller sets, each guideway and / or Slideway is assigned to a roller set. The mechanical effort for that The guidance of the idler rollers or roller sets is reduced if the Roller sets are then connected to each other via roller cages, especially if the roller sets are designed as chains.

In order to achieve even force distributions, the Guideways and slideways uniform and / or with the same width opposite. It is also advantageous if at least one Relief recess, the roller guide and / or the sliding surface in the middle Splits. In a particularly preferred embodiment there are two Guideways and / or two slideways provided.

In addition, the tension members can be connected by means of a connecting bolt be connected, with the tension members on both sides of the connecting bolt Rollers and / or tension pieces are arranged. An even one Force introduction and force distribution is favored when the jaws and the sliding surfaces on opposite, mutually parallel sides of the Tension members are arranged, the clamping hooks and the sliding surfaces or slideways can be integrated in one piece in the tension members.

In a further preferred embodiment, the idler rollers are formed at least from two sub-roles on a common axis are stored. This arrangement is particularly cost-effective since it is compatible with Standard components can be realized and still have the same advantages as the arrangements previously described. Preferably between a spacer, for example one on the axle arranged sleeve, may be provided.

In this embodiment in particular, it is advantageous if the Idler rollers are connected to a chain. Since the tabs of the Chain overlap partially, is a bending of the chain in the side Direction possible only to a limited extent. This creates in a simple way an outer guide of the idler rollers or the partial rollers. This outer Leadership can take on laterally acting managers.

It is particularly advantageous that inner guide elements act laterally Executives can take on, where they run with the roles and are arranged at the level of the contact surface division and in the lateral Direction not effectively in contact with fixed guide elements come. Because the inner guide elements are independent Executives can take on internal components, which in In the form of fixed guide elements, to be dispensed with. By eliminating such fixed Among other things, management elements also released space, which in turn for a more compact design is available.

Lateral executives are understood to mean forces that have a force component, which in the longitudinal direction to the The guiding surface has a fictitious orthogonal plane.

It is also advantageous that by saving fixed Guide elements cuts the cost of construction, the Manufacturing and later also the maintenance arise.

The inner guide elements are advantageously parallel to the Sliding surface and between the sliding surface and the guide surface arranged.

Also in the embodiment in, for example, the idler rollers parallel roller sets exist, these are inner Guide elements also arranged. This can be fixed on components on the side for guiding the idler rollers are dispensed with.

Further advantages and refinements of the invention emerge from the following description of schematic basic representations of alternative embodiments of the invention. The drawing shows:

a longitudinal section through a chain drawing machine, which illustrates the principle of operation of a chain drawing machine.

Fig. 1 shows in principle the drive chain guide one essentially shown chain pulling machine. The drawn goods with 1 is between the jaws 2 of an endlessly rotating upper drive chain 3 and an endlessly rotating lower drive chain 4 is clamped. The Drive chains 3, 4 each consist of several identical to each other trained tension members 5A, 5B, which by means of a connecting bolt 6 are connected to one another, the clamping jaws 2 on the outside 5 ' the tension members 5A, 5B, based on the orbit of the drive chains 3, 4, are arranged. The tension members 5A, 5B are connected by nuts 7 secured.

The chain pulling machine has to drive the drive chains 3, 4 Spaced from each other, not shown here, sprockets, their teeth e.g. with the connecting bolts 6 directly or via tension pieces 5A work together. 3.4 are preferably two for each drive chain spaced sprockets between which the Drive chains 3,4 through and around. In this way it becomes a drive guaranteed laterally of the tension members.

The drive chains 3, 4 are supported along a drawing line on which the Clamping jaws 2 are pressed against the drawn material 1 via idler rollers 8 a rigid one, generally designated 9 and on the machine frame 10 arranged guide surface. The guide surface 9 has a center Relief recess 11 that the guide surface 9 in a first Guideway 9A and a second guideway 9B divides. For the Rolling contact of the idler rollers 8 with the tension members 5A, 5B instruct them of the jaws 2, i.e. on the outside 5 'parallel opposite inner side 5 '' designated overall by 13 Sliding surface on which by means of a relief recess 14 in a first Slideway 13A and a second slideway 13B is divided.

For an optimal adaptation of the idler rollers 8 to tolerances on the Guide surfaces 9 or sliding surfaces 13 have the continuous idler roller 8, which are preferably at least across the width of both guideways 9A, 9B or both slideways 13A, 13B, one Circumferential taper 15 in the form of a specially adapted groove or the like .. The circumferential taper 15 ensures that the idler roller 8 bend elastically and thereby with their flat sections 8A, 8B optimally to the guideways 9A, 9B and slideways 13A, 13B can create, so that the entire width of the sections 8A, 8B at the Support of the tension members 5A, 5B is available as the wing. The through the circumferential taper 15 and the relief recesses 11, 14 in the storage of the drive chains 3, 4 introduced elasticity causes Increase the load capacity or actual load capacity of the entire Chain pulling machine. The idler rolls 8 can special rolls Be guides or, as shown, connected to tabs 16 Roller chains must be executed. Since the tabs 16 are in the immediate Surroundings of the connecting bolts 6 partially overlap each other and allow only a limited lateral bending of the roller chain, executives acting on the side can therefore partially compensate. The tabs 16 take the task of a direct external leadership true. The special guides can be internal Guide elements 31 may be formed. These inner guidance elements can accommodate laterally acting managers and thus the Hold idler rollers 8 in the area of the guideways 9. This can help fixed guide elements between the sliding surface 13 and Guide surface 9 are arranged to be dispensed with.

It is understood that the representation of the geometries of the relief recesses 11, 14, of the guideways 9A, 9B of the slideways 13A, 13B and the circumferential taper 15 serves only for illustration and is therefore pure is exemplary; the actual optimization of these geometries takes place in Dependence on the overall machine concept. The relief cutouts 11, 14 and the circumferential taper 15 and the guideways 9A, 9B and the slideways 13A, 13B can preferably, as shown, be designed such that they each have the same width dimensions exhibit.

In Fig. 2, an alternative embodiment is only in one half shown. The same components are provided with the same reference symbols. The The difference to the embodiment according to FIG. 1 lies in the structure of the Idler rollers 18. The idler rollers 18 here consist of two sets of rollers 18A, 18B, consequently from parts divided over the guide surface or sliding surface individual idler rollers; the first castor set 18A is the guide and Assigned slideways 9A, 13A, the second roller set 18B is the Guide and slideways 9B, 13B assigned. The roller sets 18A, 18b can be connected together, e.g. via roller cages (not shown), and / or the idler rollers 18 of the respective idler roller sets be connected to one another via tabs 16 as shown. Here too the tabs 16 can provide direct external guidance, since the Lateral executives can accommodate tabs. You can the inner guide elements 31 laterally acting managers record, so that fixed guide elements also in this alternative embodiment for a perfect function in the field The drawing distance of the chain drawing machine is no longer required.

In the embodiment shown in FIG. 3, there are 28 for the idler rollers two partial rollers 28A, 28B are provided, which are arranged on an axis 29 are. In addition, there is a spacer 30 on the axis 29 between the Sub-rollers 28A, 28B arranged to guide the idler rollers 28th serves.

In this embodiment, the relief cutout is dispensed with, and the adaptability or flexibility of the idler rollers is due to the Spacer 30 between the partial rollers guaranteed. The Spacer 30 also represents an inner guide element 31 this embodiment is again based on fixed guide elements dispensed with, since the inner guide elements 31 act laterally Managers can accept. Because also in this embodiment side tabs 16 connect the idlers with each other, can Here too, tabs take on direct external guidance.

In the embodiment shown in FIG. 4, there are 28 for the idler rollers two partial rollers 28A and 28B are also provided, which are arranged on an axis 29 are arranged. Is between these two sub-rollers 28A and 28B again an inner guide element 31 is arranged. Also in this Embodiment are the idler rollers 28 as with side tabs 16 connected roller chains. Between the inward facing idler surface 32 of the tabs 16 and this opposite side surfaces 33 (side surface of the Machine frame 10) and 34 (outer lateral surface of idler rollers 28) and 36 (lateral surface of the tension members 5) is a guide tab 35 arranged. This guide tab 35 is made of a slidable material and keeps the tools in a preferred position. The glides Guide tab 35 in its inner upper region on the side surface 33 of the machine frame 10 and in its lower inner region on the lateral surface 36 of the tension members 5. On the outer lateral area is the guide tab 35 partially with the side tab 16 in Contact. The guide tabs 35 preferably take no or only very low tensile forces.

In Fig. 5 is a longitudinal section of a chain drawing machine 38 with an endless revolving upper drive chain 3 and an endless revolving lower Drive chain 4 shown. The tools run at a central axis 39 or the tension members of the two drive chains 3, 4 together such that they the drawn material 1 in the direction of arrow 40 from left to right through the Convey chain puller 38. One drive chain overflows two sprockets 41 and 42, each with one of the sprockets as a drive serves. The teeth of the sprockets 41, 42 engage in the spaces between the connecting bolts 6 and thus act with the Connecting bolts 6 of the drive chains 3, 4 together. Between Tension members 5 and the machine frame 10 are the idler rollers 18 and 28 arranged. These idler rollers 18, 28 are particularly in the Work area 43 with the tension members and the machine frame 10 in Rolling contact and transfer the arising in the work area 43 Compressive forces on the machine frame 10.
