Description

TECHNICAL FIELD [0001] The present invention relates to a processing station for continuous metal profile processing,

The present invention relates to a machining station for machining a continuous metal profile according to the preamble of claim 1.

The processing station includes a press frame having a plurality of replacement modules, the replacement module comprising at least one tool carrier having a plurality of processing tools acting on a metal profile, Can be inserted. The press frame is provided with at least one lifting device for causing a tool carrier of the inserted replacement module to stroke. The press frame also has two front sides and two broad sides through which the metal profile penetrates.

Generally, such a processing station is used in conjunction with a profiling machine, which forms a continuous metal band in the form of a profile with a number of roll forming tools. In this case, the continuous metal profile, which is the state before it leaves the profiling machine and separates into the respective profile parts, is guided through the processing station. The processing station forms a plurality of embossing and / or punching in the metal profile or trimming the edge of the metal profile.

This type of machining station is subjected to a start-stop operation, i. E. A stroke movement of the tool carrier, which is operated via the lifting device of the press frame, . The stroke movement allows the machining tool to act on the metal profile, for example, to penetrate the embossing, punching, bending and / or edge side cutting surfaces. After the end of the stroke motion, the metal profile is separated from the tool and can be transported again. The metal profile is temporarily stopped in the downstream of the processing station to cut the continuous metal profile into the respective profile parts.

When manufacturing metal profiles, there is often a need to modify embossing, punching, and the like that are manufactured at the processing station to form other embossing or punching shapes in stroke motion. Thus, in this type of processing station, the tool carrier is integrated into the replacement module, which can be detached or inserted from the press frame.

The length of the replacement module or tool carrier must match the length of the profile part being manufactured and the cutting station and cutting device must be of metal profile And can be operated together for cutting of each profile part in the stopped state.

The tool carrier requires a large guiding device because the force generated when the tool carrier is stroking is relatively strong. In general, the elements of such guide devices, for example guiding columns, should be arranged on the right and left sides of the production direction of the penetrating metal profile. Thus, the replacement module can be separated from the press frame only when there is no metal profile extending therefrom.

A profiling machine is suitable for mass production of profile parts because the profiling machine can profile long and continuous metal bands in a relatively short time. Deformation in the form of profiles is generally expensive due to the fact that many roll forming devices have to be replaced. Also, the processing station, which is the subject of the present invention, has the disadvantage that it must idle every time to replace the replacement module if the profiling machine is followed, because the replacement module can not be detached from the press frame if the metal profile is penetrated . This is particularly disadvantageous when only the tool carrier needs to be replaced to provide a metal profile with another embossing shape, another punching shape, another trimming cut, or the like, without changing the profile shape itself.

Accordingly, it is an object of the present invention to provide a machining station for machining a continuous metal profile as described above that is improved to enable the replacement of a tool carrier more easily.

The above object is solved by a processing station having the features of claim 1. [ Preferred embodiments of the processing station according to the invention are described in claims 2 to 8.

That is, according to the present invention, the above-described processing station can be inserted into and removed from the press frame through the front side during use of the press frame. In order to remove the replacement module from the press frame, the replacement module is moved in the direction of movement of the metal profile or in the opposite direction. While the metal profile passes through the processing station, the replacement module is moved along the metal profile. Thus, there is no need to remove the metal profile from the machining station to insert or remove the replacement module into the press frame, i. E. There is no need to idle the machining station.

Preferably, the replacement module of the processing station according to the invention is provided with a guiding post for guiding the tool carrier during stroke movement. This guiding column ensures that the tool carrier can be accurately guided even when large forces are applied. If the guiding post is part of a replacement module, the lifting device can be provided, so that the press frame can be made simple and simple, and the lifting device can affect the tool carrier of the replacement module without a great requirement for guide movement have.

More preferably, the guiding post of the replacement module may be provided with a spring element that biases the tool carrier to the base point, at which point the processing tool does not affect the metal profile. This allows the press frame of the work station according to the invention to have a simpler configuration, since the lifting device has to act only in one direction to move the tool carrier so that the machining tool influences the metal profile to be. The spring element causes the tool carrier to return to the base point again when the lifting device of the press frame is released.

An important advantage of such a spring element is that the replacement module of the processing station according to the invention is always placed at the base point without external influences due to the lifting device. At this base point, the machining tool maintains a gap with the metal profile so that the replacement module can be moved along the metal profile. This presupposes that when the metal profile is continuously guided past the machining station, the replacement module can be inserted into and separated from the press frame through the front side of the press frame without problems.

In a preferred embodiment of the processing station according to the invention, the guiding posts of the replacement module are preferably arranged on both sides of the guiding section provided on the replacement module for the metal profile. This makes possible a particularly stable guide of the tool carrier, in particular ensuring correct parallelism when the tool carrier is moving in a stroke. According to the present invention, there is no disadvantage even if the guiding columns are arranged on both sides of the guiding section for the metal profile, since the press frame is moved in the longitudinal direction along the metal profile for insertion and separation of the replacement module.

The replacement module of the work station according to the present invention is preferably formed with a base part and a tool carrier relatively moving in the direction of the base part. The base part is provided with a bed suitable for the metal profile to be machined. Such a bed may, in some cases, be provided with a processing tool, for example, when embossing is to be formed on both sides of the metal profile. Since the tool carrier of the replacement module is formed in conformity with the shape of the basic part and the shape of the metal profile, the bed of the basic part is used as a counter bearing for the metal profile when the tool carrier moves in a stroke. During stroke movement of the metal carrier, the metal profile is clamped between the bed of the basic part and the tool carrier, and is machined through the tool carrier and / or the processing tool in the bed of the basic part. As discussed above, such processing tools may be punching tools, embossing tools, cutting tools, and the like.

A further preferred embodiment of the processing station according to the invention is characterized in that lateral supports are provided on the width broadside of the press frame, the side supports being connected to one another in the connection area at the top of the replacement module, Lifting device . This sets the preferred orientation of the replacement module, in which the moving tool carrier is arranged at the top and the stroke movement is downward movement. However, other directions are also conceivable within the scope of the present invention, and stroking motions can be considered, for example from below or from the side. The orientation setting is determined according to how the metal profile in the spatial direction is inserted into the machining station, i. E. Generally, from the profiling machine upstream.

The lifting device of the processing station according to the invention is preferably generally constituted by at least one hydraulic or pneumatic piston-cylinder-unit. The piston-cylinder-unit may be provided with a hear plate that affects the replacement module. This head plate distributes the force generated by the piston-cylinder-unit to the replacement module surface.

Another preferred embodiment of the processing station according to the present invention may comprise at least one magazine for a plurality of replacement modules, which are arranged downstream and / or downstream of the press frame with respect to the direction of transport of the metal profile It is provided upstream. A plurality of replacement modules can be used through such a magazine, and according to the invention, the replacement module can be detached from the press frame and inserted into the press frame in an end face, but in the region of the magazine, Can be laterally separated relative to the direction of transport of the metal profile, and can be replaced by another replacement module. It is possible that two or more different replacement modules are provided in each press frame.

Hereinafter, embodiments of a processing station according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a top perspective view of the processing station of Figure 1;
Figure 3 is a detail view of the replacement module of the processing station of Figure 2;
Figure 4 shows the processing station of Figure 1 when replacing the replacement module.

The embodiment of the processing station according to the invention shown in Figures 1 to 4 is arranged in a straight line with respect to the downstream of the profiling machine (not shown). The profiling machine is provided for later profiling, i.e. for punching inserts. To this end, the continuous metal band in the profiling machine is continuously formed into a desired metal profile, which is guided through a processing station where punching is provided. The continuous metal profile is then separated into individual profiles.

The specificity when manufacturing such a profile is that two different profiles should be produced that differ only in the profile form but only in the punching pattern (left / right). The production position change and reverse change from the "left" profile to the "right" profile is not associated with a change in the profiling machine, but only with the replacement of the replacement module at the machining station. If desired, a plurality of processing stations arranged in a straight line are provided, for example for embossing, punching and trimming.

This particularity is predominantly found in the automotive industry, where nine different profiles have to be made to manufacture the vehicle, and these different profiles, such as rocker profiles or sheet guide rails, Or embossing type.

The machining station shown in Figure 1 consists essentially of a press frame 1 of welded and screwed plate construction with two side supports 2 which are arranged in the direction of movement of the metal profile 4 Are arranged on the right and left sides of the metal profile along the bottom surface 3, and are implemented at the floor height. The side supports 2 are connected to each other in the upper connection area 5 and have a lifting device (not shown). The side supports 2 of the press frame 1 are connected to each other by a table element 6 at the height of the through metal profile 4. This table element (6) has a replacement module (7) for machining the metal profile (4).

As shown in FIGS. 1 and 2, magazines 8 and 8 'are arranged in the upstream and downstream directions of the press frame 1, respectively, and a plurality of replacement modules 7 and 7' , 7 '', 7 '' 'are fixed and can be separated or inserted laterally from the conveying path of the metal profile 4.

Figure 1 shows two replacement modules 7 and 7 'and the first replacement module 7 is arranged in the press frame 1 to influence the metal profile 4, whereas the second replacement module 7 7 'lies in a stop position downstream of the press frame 1 and the metal profile 4 penetrates the replacement module 7'. The replacement module 7 'has to be able to be detached from the press frame 1, that is to say separated from the conveying section of the metal profile 4, according to the invention; Even if the replacement module 7 'is separated through the front side of the press frame 1, the metal profile 4 can penetrate through the press frame 1 unchanged.

Figure 2 is a top perspective view of the processing station of Figure 1; There is thus seen a lifting device 9 arranged between the two side supports 2 in the connecting region 5, which is formed by two hydraulic piston-cylinder-units 10. The lifting movement of the lifting device 9 is carried out in the following manner since the piston rod of the lifting device 9 is connected to the head plate 11 which can influence the tool carrier 12 of the replacement module 7: Causing the tool carrier 12 of the replacement module 7 to stroke.

To this end, the replacement module 7 is provided with four guiding posts 13, which guide the tool carrier 12 during stroke movement, and when the tool carrier 12 is in a stroke movement Do not allow movement in three dimensions. Two guiding columns 13 are arranged on both sides of the metal profile 4, respectively.

The replacement module 7 is shown in more detail in FIG. The replacement module 7 comprises a tool carrier 12 which is here comprised of a tool carrier profile 14 and a compression plate 15 and the compression plate 15 is connected to a lifting device 9 ) Of the head plate 11 and acts together with the guiding post 13. The guiding post 13 is provided with a spring element 16 which is supported between the base plate 17 of the replacement module 7 and the compression plate 15 and which is supported by a tool carrier 12) to the base point. At this base point, the metal profile 4 can penetrate the replacement module 7 without contacting the tool carrier 12.

The base plate 17 of the replacement module 7 is part of the base part 18 of the replacement module and the base part 18 includes a bed 19 in addition. The bed 19 has a shape suitable for the metal profile 4. This is also applied to the tool carrier profile 14 so that the metal profile 4 is positioned between the bed 19 and the tool carrier profile 14 when the tool carrier 12 is under pressure by the lifting device 9. [ And is suitably clamped.

At the base point of the replacement module 7 shown in Fig. 3, the tool carrier profile 14 and the bed 19 are spaced from one another so that the metal profile 4 can penetrate in the longitudinal direction without contact.

Figure 4 shows how the first replacement module 7 is replaced: two replacement modules 7, 7 'are slid along the carrying direction 3 of the metal profile 4 and the first replacement module 7 Is removed from the press frame via the first front side 20 of the press frame 1 while the second replacement module 7 is removed from the press frame 1 via the second front side 21 of the press frame 1, . To this end, the lifting device 9 is moved upward.

The metal profile (4) can remain unchanged during replacement at the processing station; It need not be removed from the processing station for modification. The "left" to "right" profile of the machining station can be modified without detaching the metal profile 4 from the machining station. Rather, the modification can be carried out while the production is stopped, and the production can be restarted tightly.

This modification of the machining station can be carried out manually or automatically, and the replacement module can be inserted into or removed from the machining station via a suitable drive.
