Definitions

  • the invention relates to a system for welding and deburring rim blanks acc. the preamble of claim 1.
  • the invention is based on a manufacturing process for blank blanks in which rim rings are bent from sheet metal strips and welded at the joints. This work sequence is followed by a deburring process at the weld seam.
  • a device for processing the weld seam is known in which the rim blanks are moved between the individual stations for seam processing on a U-shaped path.
  • the welding machine and its feed device are not mentioned there.
  • This system also shows seam processing machines which have a tool slide for guiding the tools and which comprise the means for holding the rim blank.
  • a disadvantage of this device is that the transport path of the rim blank between the individual stations consists of 3 sections, the first of which essentially runs in the axial direction, the next transversely thereto and the third finally again in the axial direction. Each section is associated with acceleration and braking. This takes time and extends the cycle time of the system.
  • DE-OS 2 717 509 From DE-OS 2 717 509 it is known to guide the rim blank axially through the welding machine and also to feed it to the next station in the axial direction for further processing.
  • DE-OS 2 555 660 A disadvantage of these machines is that they require a continuous mandrel over which the rim blank is pushed from station to station. The tools, which are partially arranged within this mandrel, are difficult to access. It is not possible to remove a single rim blank from the mandrel because it is already welded together and encloses the mandrel.
  • a system for welding and deburring rim blanks which has a welding machine and a deburrer in addition to a bending machine.
  • the welding machine and deburrer are arranged one above the other.
  • the rim blank is pulled out of the welding machine in the axial direction and swung into the area of the deburrer on a curved path.
  • the transport is carried out by a carriage which can be moved in the axial direction of the rim blank and has a swivel device arranged thereon.
  • a disadvantage of this system is that the transport route between the welding machine and the deburrer, as in the aforementioned FR-OS 2190547, runs in 3 phases and is therefore time-consuming. In cooperation with the cycle time sections then required for clamping the rim blank, extensive cycle times result for the transport of the rim blanks. In addition, the transport carriage for the rim blanks is structurally quite complex due to the use of the swivel device arranged thereon.
  • the object of the present invention is to avoid the aforementioned disadvantages in the prior art and to improve the material flow in the system.
  • this object is achieved by the characterizing features of claim 1.
  • the rim blanks are transported in one go between the welding machine and the seam processing machines.
  • the clamping jaws of the welding machine are retracted and the fig blanks can be transversely transported directly into the rigid U-shaped receptacles in front of the seam processing machines.
  • Another advantage of the solution according to the invention can be seen in the fact that the welding machine and the workpiece located therein remain easily accessible even in the case of feed machines arranged axially in close succession to the welding machine. In the event of a malfunction in the welding machine, the individual workpiece can be removed from the welding machine without first having to go through all the stations or without having to cut the rim ring.
  • This arrangement of the seam processing machines next to each other also allows a quick tool change and, just as with the welding machine, quick troubleshooting.
  • the claimed U-shaped, rigid receptacles for the rim blank are based on the idea of machining the weld seams without clamping the rim blank. With their legs pointing vertically upwards, the U-shaped receptacles serve for their axial fixation. Their arrangement on the side of the seam processing tools also ensures that the rim blank is fixed in the transverse direction. Due to the missing tensioning process, the cycle time for the seam processing stations is significantly reduced. The advancement of the clamping tools, the clamping itself, the relaxation and retraction of the clamping tools is saved in the cycle time. The clamping tools themselves and their controls can be omitted.
  • the arrangement of the annular gap orientation station and the round bending station in front of the welding machine is made possible by the movability of the clamping jaws of the welding machine.
  • the pre-arrangement of these machines can be done without any intermediate technical requirements space and allows the shortest possible transport routes between the neighboring machines.
  • Their arrangement in axial order is basically z. B. from the aforementioned DE-OS 2 555 660, but the embodiment of the invention discussed here has the advantage that it combines accessibility and shortest transport routes.
  • Grippers for rim blanks are widespread in the prior art (e.g. DE-OS 2 022 424) and absolutely necessary for transporting them between individual machines.
  • the embodiment of the invention pursued with claim 3 allows the rim blank to be transported from station to station in one go on an arcade-shaped path. This prevents multiple accelerations and decelerations between two neighboring stations.
  • the features pursued with claim 4 ensure that the transport of the rim blank, including clamping for the transport, is not impaired by the amount of chips occurring during seam processing.
  • the transport grippers grip the rim blank in its upper area, while the seam is arranged below.
  • the features according to claim 5 are provided. They serve to improve the cutting result because they soothe the workpiece, which is otherwise not clamped.
  • the U-shape of the supports for the rim blank is given in two ways. On the one hand, the uptake of the rim blank in the seam area is excluded and, on the other hand, the U-shape of the support is given in a right-angled view by the fact that the vertical legs of the "U" grip it on its two end faces and thus fix its position.
  • the rim blanks should preferably be transported in such a way that the rim blank is placed transversely to its longitudinal axis in the U-shaped supports, since it is then possible to directly insert it on a curved track.
  • Fig. 1 shows a system for the production of rim blanks 15-19, the machines are arranged overall in a Z-shape.
  • the system consists in detail of a feed device 1, which forms a first leg of the "Z", of three machines, namely a round bending machine 2, an annular gap orientation station 3 and a welding machine 4, these machines making up the central web of the "Z", at the end of which the welding machine is arranged and consisting of several seam processing machines, of which a longitudinal seam deburring machine 5, a seam smoothing machine 6 and a side seam deburring machine 70 are shown.
  • the structure of the system is shown in top view.
  • Fig. 2 the machines are shown partially folded.
  • the individual machines are shown schematically in boxes representing the machine frame.
  • the swivel axes are labeled 47 ... 55.
  • the lower half of the illustration is pivoted again by 90 ° about the axes 52, 54 in order to be able to better show the function of the tools.
  • the seam smoothing machine 6a is shown entirely in front view.
  • the illustration according to FIG. 2 shows that the sheet metal strip 14, 14a is fed from the feed device 1 by means of the rollers 37, 38 on a roller conveyor 56 of the bending machine 2 according to arrow 46.
  • the incoming flat sheet metal strip is bent into a ring by the rollers 20, 21 and 22.
  • the sheet metal strip which has already been bent in its longitudinal section on the inlet side is moved according to arrow 57 on a circular path within the bending machine 2.
  • Several slides 58, 59, 60 transport the ring 15, which has not yet been closed, in the direction of its longitudinal axis into the annular gap orientation station 3.
  • the gap 62 must be arranged in its rotational position between the ends of the bent sheet metal strip in such a way that it corresponds to the intended position of the weld seam of the ring in the welding machine.
  • the rollers 26, 27 on which the ring 16 rests rotate it until the stylus 25 can engage in the gap between the ends of the ring 17 which is still open.
  • the ring is gripped by the pairs of clamping jaws 23, 24 after the stylus 25 has engaged.
  • the stylus 25 is withdrawn.
  • the rear end 63 seen in the direction of arrow 61, is pressed against the front end 64 held in place by the pair of clamping jaws 23.
  • the necessary closing movement of the gap 62 takes place through the pair of clamping jaws 24 for the rear end of the rim blank 16.
  • each ring 15, 16 is only axially, namely by slides 58 ... 60 or clamping jaws 23, 24 of the station to be exited moved forward and transported into the next machine.
  • the welding machine 4 forms the end point of the axial transport path.
  • the clamping jaws of the pairs of clamping jaws 28, 29 arranged in the rim blank are opened and pulled backwards, that is to say in the axial direction, to the rim blank 17.
  • a gripper 8 has meanwhile gripped the rim blank 17 from above and is transporting it in the direction of arrow 42 into the longitudinal seam deburring machine. During this hanging transport, the gripper 8 is moved via an upwardly curved guide 13, on which a roller 41 of the gripper travels.
  • This transport takes place by means of a transport device 7 arranged above the welding machine and the seam processing machines, which has a gripper 8, 9 and 10 for the seam processing machines 4, 5 and 6.
  • the grippers 8, 9 and 10 grip the respective workpiece 17, 18 and 19 from above.
  • the weld seam is arranged at the bottom in all seam processing stations.
  • the welded ring 18, 19, 19a is received and held in U-shaped supports 30, 31 and 32 which are open at the top and are arranged on both sides of the weld seam.
  • the width corresponds to the width of the rim blanks to be machined.
  • the rim blank is held from below in two U-shaped supports, of which only one, the support 30, is shown.
  • two supports are arranged in accordance with the supports 31, 32 of the seam smoothing machine 6a.
  • the mouth-like front part of the knife carriage 34 is guided according to arrow 65 with its two knives 33 directed inwards over both sides of the longitudinal seam of the rim blank 18 and deburrs it in the process.
  • the rim blank can be lifted upward and / or diagonally upward out of the U-shaped supports.
  • the transport means 7 is moved from the area of the seam processing stations, and not properly machined workpiece can be individually and do without influencing the work pieces in the adjacent equipment and without destruction of the machining g sstationen 4,5 and 6 are removed.
  • the rim blank 18 is gripped by the gripper 9 and transported to the seam smoothing machine 6 on an arcade-shaped path according to arrow 43.
  • the transport device 7, which can be moved back and forth with the rollers 39, 40 and 41 on upwardly curved guides 11, 12, 13, travels back and detects the workpieces brought into the processing machines by grippers 8 ... 10.
  • the processing operation in the Nahtglättmaschine is similar to that in the L Lucassnahtentgrat - machine.
  • a jaw-shaped tool carrier with smoothing rollers 35 is provided on a slide 36 and rolls the remaining degree away, so that the seam cross section is equal to the rest of the strip cross section.
  • the rim blank 19 and 19a of the illustration according to FIGS. 3 and 3 is located in two U-shaped receptacles 31, 32 which center the rim blank with the base surfaces being slanted and between which the smoothing tools roll the remaining degree away.
  • the supports 31, 32 are interrupted in the area of the seam and are therefore also U-shaped in this view.
  • the rim blank 19 is conveyed from the gripper 10 to the next side seam deburring machine 70, which is only shown in FIG. 1.
  • the gripper 10 also hangs on a roller 39 which, on an upwardly curved guide track 11, transports the rim blank 19 on an arcade-shaped track to the next processing station.
  • the processing point is on the front of the machine, so that the tools and workpieces are easily accessible in the event of a malfunction and if the tools wear out and can therefore be replaced quickly.
  • the transport movement of the closed rim blank 17, 18 and 19 on a non-angular path is considered to be particularly advantageous, which permits high accelerations and thus enables short transport times and the transport movement is adapted to the U-shape of the supports arranged on both sides of the interface.
  • the positive locking of the workpiece by the U-shaped supports 30, 31, 32 on both sides of the interface eliminates the need for time-consuming, non-positive clamping, so that the clamping times are eliminated.
  • FIG. 4 shows an enlarged front view of a schematically reproduced longitudinal seam deburring machine.
  • the knives 68, 69 travel in the axial direction of the rim blank 78 over the longitudinal seam 71.
  • the knives are received in a jaw-like knife carriage in two knife holders 72, 73.
  • Two guide rollers 66, 67 are provided on each side next to the knives 68, 69 and are arranged in a transverse plane of the rim blank. The guide rollers ensure that the planed surface corresponds approximately to the curvature of the rim blank to be produced.
  • U-shaped supports 75, 76 are provided on both sides of the guide rollers 66, 67, in which the rim blank 78 is held.
  • a cutout 74 is provided between the U-shaped supports in the area of the longitudinal seam 71 and forms an additional U-profile in connection with the supports.
  • the longitudinal seam 71 is arranged centrally in the cutout 74 and forms the lowest point of the rim blank. The blank of the rim is calmed and clamped during the cut by the guide rollers 66, 67 lying opposite one another in pairs.
