Definitions
- the invention relates to a forging and rolling device and a forging and rolling method for pressure forming of workpieces by rolling.
- the forging and rolling device has a pair of work rolls with two rolls, which implement several stages in the axial direction, which are set up for the step-by-step deformation of the workpieces, in that the workpieces successively pass through the stages.
- the forging process is one of the longitudinal rolling processes in which the rolled material is transported through the roll gap perpendicular to the rolling axes and is formed in the process.
- This is characterized by the fact that a blank to be rolled, for example a round or square material, is fed to the rollers by a manipulator and in individual stages that are arranged in the axial direction of the rollers and also as “stitches", “calibres” or “sectors "Are called, is transformed.
- the steps of the rolls consequently mostly have different roll profiles and are traversed one after the other by the blank to be rolled, whereby the profile cross-section of the blank is changed step by step.
- Forging rolling is particularly suitable for the production of intermediate forms, such as semi-finished products or preforms, and in rare cases also of finished molded parts.
- downstream processing steps such as, for example, die forging
- forging rolling can be simplified by the forging rolling.
- forging is used, for example, to produce intermediate forms for components such as crankshafts, axles and link components.
- DE 10 2014 101 150 A1 describes a forging and rolling device which has a pair of rollers with two reversible rollers and two gripping devices for handling the workpieces to be rolled.
- the two gripping devices are arranged on opposite sides of the pair of rollers.
- the rolls have at least two rolling tools, i.e. stages, in the axial direction, the stages being set up for the gradual deformation of the workpiece.
- the output of the workpieces is limited by the fact that the handling of the workpieces by the two gripping devices always only requires part of the pair of rollers, i.e. not all stages are used simultaneously.
- a forging roller device according to DE 10 2016 112 946 A1.
- several gripping devices are installed on the opposite sides of the pair of rollers, two opposite gripping devices, which form a pair of gripping devices, being assigned to a step and gripping the corresponding workpiece.
- the forging and rolling device has a transfer device in order to convey the workpieces from pair of gripping devices to pair of gripping devices in the working cycle of the device.
- One object of the invention is to provide an improved forging and rolling device and an improved forging and rolling process, in particular to achieve a high output of workpieces with a reduced structural complexity.
- the object is achieved with a forging and rolling device with the features of claim 1 and a forging and rolling process with the features of claim 9.
- the forging and rolling device according to the invention is used for pressure forming of workpieces, preferably metallic workpieces, by rolling.
- the forging roll device has a pair of work rolls with two rolls, which can each be rotated about their roll axes and form a roll gap between them.
- the rollers are set up in such a way that they implement several stages in the axial direction, which are provided for the step-by-step deformation of the workpieces, in that the workpieces successively pass through the stages.
- the work rolls rotate in opposite directions.
- the work rolls can be reversible in the direction of rotation. However, this is not absolutely necessary.
- the rolled profiles differ on the different stages in order to carry out a step-by-step reshaping of the workpieces.
- Each workpiece preferably goes through all stages, from the lowest level to the highest level.
- steps act on the workpieces, ie steps are omitted or skipped.
- steps are omitted or skipped.
- the terms “successive”, “step-by-step” etc. do not necessarily limit the processing to a complete run through of all available stages.
- the forging and rolling device also has one, preferably precisely one, manipulator with a plurality of gripping devices.
- the number of gripping devices is preferably equal to the number of stages.
- the gripping devices preferably the entire or essentially the entire manipulator, are arranged on one working side of the pair of work rolls and are set up to grip the workpieces and to guide them through the nip at an associated step in a feed / retraction direction.
- the working side is defined by the position of the pair of work rolls and the gripping devices.
- the side opposite the work side (relative to the work roll pair) can be designed as a tool change side, via which maintenance work, such as a roll change, can be carried out.
- the forging and rolling device also has a shelf which is set up to temporarily support workpieces and, in cooperation with the manipulator, to transfer them to another gripping device, preferably the adjacent gripping device of the next higher level.
- the workpieces are transferred from one gripping device to another gripping device, preferably a gripping device of a higher level, for example the next higher level.
- This transfer of the workpieces usually takes place once per work cycle of the forging roller device.
- the workpiece that has been completely processed, preferably the workpiece of the highest level is ejected. Furthermore, a new work piece, which is also referred to herein as a blank, is fed to the lowest processing stage.
- the Transfer of the workpieces normally only the first workpiece (the blank) to the penultimate workpiece is gripped and picked up by a gripping device.
- the term “finished workpiece” only refers to the forging process, ie it does not necessarily refer to an end product or finished part. Rather, the finished workpiece, which has passed through all the intended stages of the forging roller device, is preferably an intermediate molding, such as a semi-finished product or preform.
- the shelf is not a manipulator, since the shelf does not have any gripping devices which are set up to grip the workpieces and to guide them through the nip in a feed / retraction direction.
- the tray has no gripping devices that enter the nip or pass through it or can pass through it.
- the storage can be set up passively in that the workpieces are placed thereon for transfer or the storage supports the workpieces without actively grasping or clamping them.
- the shelf can have holding means which are set up to hold or stabilize the workpieces temporarily, for example to grip or clamp them.
- the forging and rolling device constructed in this way allows several workpieces to be processed simultaneously by occupying all or at least several stages in parallel, for example every second stage. Due to the parallel assignment, the output of the workpieces and thus productivity can be increased. This is achieved without installing two or more manipulators on opposite sides of the pair of work rolls.
- the working side is only expanded to include additional gripping devices, such as tongs, as a result of which the improved functionality is achieved without a significant increase in the structural and procedural complexity of the forging and rolling device.
- the transfer of the workpieces to gripping devices in the process of the following stages is realized in connection with a deposit. In this way, a high output is compared with a realized a small number of assemblies, which also improves the reliability and maintainability of the forging device.
- One or more gripping devices are preferably designed to be rotatable about their own axis in order to enable the corresponding workpieces to be rotated between the individual stages. What is meant here is a rotation of the workpieces about their longitudinal axis by a certain angle, for example 90 °. The rotation can take place before or after the forming at the respective step.
- the gripping devices are preferably designed to grip the workpieces at one end and to guide them through the roller gap at an associated step, while the workpieces are not gripped at the other end. It is not necessary for the “second” end of the work piece to be gripped by an additional gripping device of a manipulator, which not only reduces the structural complexity but also reduces the process control.
- the tray can preferably be moved in the axial direction and / or the advance / retraction direction.
- the displaceability of the shelf can be used to implement or at least support the transfer of the workpieces by transporting them transversely through the shelf.
- the tray can be designed to be movable in the up / down direction, for example in order to submerge during rolling and not to hinder the rolling process.
- the shelf is preferably arranged on the working side.
- the side opposite the working side which is advantageously designed as a tool changing side, is not built into the shelf or has restricted access. This improves the maintainability of the forging roll device.
- the number of gripping devices is preferably equal to the number of stages, the assignment of the gripping device to the step being a one-to-one assignment. In this way, the pair of work rolls can be optimally used along the axial direction, with the nature and control of the individual gripping devices being able to be designed as best as possible for the associated stage.
- the gripping devices can preferably be moved by the manipulator in the axial direction and / or advance / retraction direction, with the manipulator itself particularly preferably being able to move relative to the work roll pair in the axial direction and / or advance / retraction direction for this purpose.
- the movability of the gripping devices or the manipulator can be used to implement the transverse transport, i.e. transport of the workpieces for the transfer in the axial direction, either in connection with a stationary shelf or by combination with a likewise movable shelf.
- at least one gripping device is preferably adjustable relative to the manipulator in the advancing / retracting direction. This can be realized by means of a length compensation section which can adjust the gripping means, for example the clamps, of the corresponding gripping device for length compensation in the advance / retreat direction.
- a length compensation section which can adjust the gripping means, for example the clamps, of the corresponding gripping device for length compensation in the advance / retreat direction.
- at least N-1 here N denotes the number of stages
- the increase in length and / or the rate of increase in length can vary from stage to stage.
- the gripping devices are thus preferably individually movable.
- the individual mobility or displaceability in the advance / retract direction can be implemented passively, for example sprung, or actively, for example pneumatically, electromotive, etc., for this purpose.
- the tray preferably has holding means which are set up to hold the workpieces temporarily for transfer to the respectively adjacent gripping device of the next higher level, preferably to clamp them, while the gripping devices grip around. In this way, the reliability of the handover can be improved.
- the retaining means are preferably essentially, that is to say for example, except for a clamping movement, stationary relative to the shelf.
- the object is also achieved by a forging and rolling method for pressure forming workpieces by means of a forging and rolling device according to the description above.
- the method comprises: gripping a plurality of workpieces by a respective gripping device of the manipulator; Guiding the workpieces through the nip formed by the pair of work rolls at an associated step in the advance / retreat direction; Rotating the rollers, preferably in opposite directions, and exerting pressure on the workpieces by the rollers, whereby the workpieces are reshaped according to their stage; Transporting the workpieces to a transfer position and supporting the workpieces through the storage, preferably placing the workpieces on the storage; Releasing the workpieces by the gripping devices; and gripping of workpieces by another gripping device, preferably the adjacent gripping device of the next higher level.
- one or more workpieces are rotated around their longitudinal axes, for example by 90 °, between the individual stages.
- the rotation can take place before or after the forming at the respective step.
- the gripping devices of the manipulator grip the workpieces at one end and guide them through the roller gap at the associated step, while the workpieces are not gripped at the other end.
- the tray For transferring the workpieces to another gripping device, the tray preferably moves in the axial direction and / or advance / retraction direction and / or up / down direction in order to realize or at least support the transfer.
- the gripping devices move through the manipulator in order to transfer the workpieces to another gripping device in the axial direction and / or the advance / retract direction.
- At least one gripping device is preferably adjusted according to the length of the assigned workpiece relative to the manipulator in the advance / retract direction.
- the gripping devices are preferably moved individually during the rolling, since the increase in length and / or the speed of the increase in length can differ from step to step.
- This can be implemented passively, for example with a spring, or actively, for example pneumatically, with an electric motor, etc.
- the number of workpieces to be rolled is preferably smaller than the number of available stages, for example approximately half as large. A reduced occupancy of the steps may be beneficial or necessary to comply with machine limits with regard to power or energy consumption.

- the side on which the manipulator 20 with the gripping devices 21 is located relative to the pair of work rolls is referred to herein as the work side AS.
- the gripping devices 21 have, for example, adjustable clamping jaws in order to be able to securely grip the workpieces W and release them for transfer.
- the manipulator 20 is in the axial direction of the rollers 10 (referred to herein as “axial direction” or “transverse direction”) and in the horizontal radial direction thereof (referred to herein as “radial direction” or “advance / retraction direction”) movable set up, as indicated in the figures by arrows.

- the gripping devices 21 enter the nip and, if necessary, with their front ends through it.
- no rolling, ie no plastic deformation of the workpieces W by the rollers 10 takes place during this transfer.
- the transfer serves to align the workpieces W, with positioning on the shelf 30, and optionally with rotation of one or more of the workpieces W about their own axes, preferably 90 °.
- the transfer to the fully advanced position has an axial component, ie the workpieces are transversely into the respective higher stage S2 to S4 shifted (upwards in the figures), as a result of which there is no workpiece W on the first stage S1 at the end of the transfer.
- a new workpiece / blank Wn is supplied to the first stage S1 by a supply device (not shown in the figures) by positioning it on the corresponding position of the tray 30.
- the supply of a new workpiece Wn is shown in FIG. 1b by an arrow.

- Forging and rolling device 1 in different process stages according to a further embodiment. Since the structure and the process sequences largely correspond to those of the embodiment in FIGS. 1a to 1c, only the differences are essentially presented below. This applies equally to the embodiment of Figures 3a to 3c and the embodiment of Figures 4a to 4c.
- the forging and rolling device according to FIGS. 2a to 2c differs from the previous embodiment essentially in that the tray 30 is arranged on the working side AS.
- the support 30 can also be provided passively, so that the workpieces W are placed thereon or the support 30 supports the workpieces W without actively grasping or clamping them.
- the tray 30 can have holding means 31 which are set up to hold the workpieces W temporarily, for example to grip or clamp them.
- the supply and discharge of the workpieces W is realized according to this embodiment on the working side AS, as can be seen from FIGS. 2b and 2c.
- an advantage of the present embodiment of FIGS. 2a to 2c is that the side opposite the working side AS, which is advantageously designed as a tool change side, is not affected by the Shelf 30 is installed or has restricted access.
- the two embodiments of Figures 1a to 1c and 2a to 2c implement the transfer of the workpieces W to the next higher level S2 to S4 essentially in that the manipulator 20 and / or its
- Gripping devices 21 are moved in the axial direction.
- the following two embodiments of FIGS. 3a to 3c and 4a to 4c implement the transfer of the workpieces W essentially by moving the tray 30 in the axial direction.
- the tray 30 is designed to be movable at least in the axial direction. It can be provided passively, so that the workpieces W are placed on it or the support 30 supports the workpieces W without actively grasping or clamping them.
- the tray 30 can have holding means 31 which are set up to hold the workpieces W temporarily, for example to grip or clamp them.
- the shelf 30 can be installed on the working side AS, as shown in FIGS. 3a to 3c.
- the shelf can be arranged on the side opposite the working side AS, as can be seen from FIGS. 4a and 4b.
- the tray 30 can alternatively or additionally be designed to be movable in the advance / retraction direction between the two sides, i.e. the working side AS and the side opposite the working side AS. Furthermore, several shelves 30 can be provided, as can be seen from FIG. 4c, for example, if this improves or simplifies the handling of the workpieces W, or in order to be able to implement various process sequences with one and the same forging and rolling device 1 without significant conversion measures.
- the workpieces W of the steps S1 to S4 normally have slightly different lengths.
- gripping devices 21 have a length compensation section 22.
- the length compensation sections 22 can be implemented, for example, by a spring system which can deflect to different extents to compensate for the length of the gripping devices 21.
- the workpieces W are rolled on the “return path”, ie during the transfer from the advanced position into the starting position of FIGS. 1a, 2a, 3a and 4a.
- a plastic deformation of the workpieces by the rollers 10 can alternatively or additionally also take place during the forward transfer, ie during the transfer into the advanced position.
- the forging and rolling concept presented here allows simultaneous occupancy of all or at least several stages S1 to S4, for example every second stage.
- a reduced occupancy of stages S1 to S4 may be necessary to comply with machine limits with regard to force or energy consumption.
- the forging and rolling device 1 enables the output of the workpieces W to be optimized through the parallel assignment. This is achieved without the need for two manipulators on opposite sides of the pair of work rolls.
- the manipulator on the working side AS is only expanded by further gripping devices 21, such as tongs, as a result of which the improved functionality is achieved without a significant increase in the structural and procedural complexity.
- the transverse transport i.e.
- transport of the workpieces W in the axial direction is implemented, for example, either by an additional transverse transport axis in the manipulator 20 in connection with a stationary tray 30 or by a combination of a manipulator 20 that is stationary in the axial direction and a tray 30 that can be moved in the axial direction. It is not necessary here for the “second” end of the workpieces W to be gripped by a further manipulator. In this way, a high output is achieved with a comparatively small number of assemblies, which also improves the reliability and maintainability of the forging and rolling device.
