Definitions

  • the invention relates to a device for producing holes in hollow plastic profile bars or frames made therefrom, in particular window or door frames, with a support table formed by a plate or a frame, with a positioning stop for aligning the holes required for making the holes machining workpiece and with a tool that is movable relative to the support table and that produces the holes.
  • a well known device of this type uses drills as tools.
  • the workpiece i.e. a plastic hollow profile rod or a frame made from it, is placed in the desired position on the support table held on to the positioning stop and tightened if necessary. Then the rotating drill is lowered, creating the hole. Drilling creates drilling chips that make up large quantities, particularly when there are a large number of holes.
  • the holes are either drilled one after the other, the total machining time required for a workpiece being relatively long, or multi-spindle drilling units are used to produce several holes at the same time, so that the machining time is kept short, but the minimum hole spacing is relatively large , because the individual drilling tools require a design-related distance from each other.
  • the invention is based on the object of improving a device of the type mentioned in such a way that the machining time of the workpiece when making the holes is reduced without the holes produced having reduced pull-out strength for fastening screws.
  • the tool is at least one punch that works without a matrix.
  • the time to make a single hole is less when punching than when drilling, where only a limited feed rate may be used during the production of the hole.
  • punching in hollow plastic profile bars creates uninterrupted holes.
  • the plastic is sufficiently elastic during a punching process to dodge in the vicinity of the hole and to return to this neighborhood of the hole without interruption after the punching process.
  • the plastic can be smeared, i.e. tends to flow or burr formation, which also contributes to achieving the desired pull-out strength or can even cause an increase because the engagement length of the screw in the plastic increases.
  • the punch or punches are assembled with a punch drive, which is releasably attached to the support table together with the positioning stop as an attachment unit.
  • a punch drive which is releasably attached to the support table together with the positioning stop as an attachment unit.
  • This also makes it possible to use the support table more universally or to integrate it in production processes that relate to different types of workpieces or in which the plastic hollow profile bars or the frames are further processed, e.g. a welding process.
  • the punches protrude from the punch side of a punch holding plate and are secured against removal from the workpiece by a pressure plate, which in turn is supported by a holding plate which can be acted upon by a piston-cylinder drive, and all three plates are seated on guide bushings which are displaceable on guide columns of a stamp drive frame.
  • This punching device is particularly suitable for a punch or a group of holes stamp exchangeable in the respective desired arrangement and to carry out tolerance-free, so that the holes can be made with the desired accuracy of their arrangement and dimensioning.
  • the guide columns of the stamp drive frame connect a cylinder holding plate with a cover plate arranged between the stamp holding plate and a base plate to form a rigid frame frame, which is supported on the base plate or on the support table by a spacer which has the positioning stop and has space on the workpiece side for the arrangement of the workpiece .
  • the rigid frame provides the guarantee for an exact guidance of the punches with secure fastening of the punch drive.
  • the frame is held high enough by the spacer above the base plate or above the support table in order to be able to arrange the workpiece to be machined on the base plate or on the support table below the tool.
  • punch groups are provided, each with a separate punch drive. It is thus possible to produce different hole patterns on a frame without having to lift the frame to another hole device or to replace or retrofit hole devices of a support table.
  • punch groups it is possible to process frames for right and left hinges better in the same way, namely without lifting the frame to another punching device or without changing or converting it.
  • the punching device has at least one positioning stop limit switch forming a punch drive lock, so that the punch drive can only be triggered when the workpiece is in the desired exact position.
  • the device has a positioning slide which is adjustable parallel and / or vertically to a stop surface of the positioning stop and with which e.g. Teaching for e.g. Locking parts can be arranged on the frame in a simple manner without the frame having to be re-aligned. The orientation of the workpiece required for punching is therefore used.
  • Two punching or punching units are arranged at right angles to one another with their row of punching or punching tools and two such groups of units are arranged with more than the largest frame side length apart from one another on one side of the support table and its support surface and facing each other, if necessary each unit group on the same side of a roller table is arranged with an operator station located between them.
  • the right-angled arrangement of the punch or perforation units is based on the right-angled design of the frame corners coordinated and enables the operator to bring a frame corner into the same stop position at all times, regardless of whether a group of holes or another group of holes at right angles to it should then be created.
  • the punching tools are, for example, the well-known cutting drills or flow formers or the like working with the supply of heat.
  • the arrangement of two unit groups at a distance from one another allows a frame to be moved between the two unit groups for machining, as a rule only relatively small displacements being required are to move the frame from a stop position in one unit group to a stop position in the other unit group.
  • the arrangement of the unit groups on the same side of a roller table saves time and energy, particularly if the operator station is arranged between the unit groups.
  • the invention also relates to a method for producing holes in hollow plastic profile bars or frames made therefrom, in particular door or window frames, in which the workpiece to be machined is placed on a support table and brought into its processing position at a positioning stop, after which the holes be generated with a tool moved relative to the support piece.
  • the known method is improved in that the holes are punched with punches. This method allows, in particular, the production of groups of holes with increased accuracy, since the tolerances given in each case with several processing steps cannot add up.
  • a frame is arranged with its frame opening around the hole device on a support table and aligned with a surface adjacent to the frame opening on the positioning stop.
  • the easy handling of the frame with several different positioning positions is particularly advantageous here. Since the dimensional specification or the distance of a hole or a group of holes is predominantly measured from an inner edge of the frame, frames of different profile dimensions or profile widths can be processed with the punching device without the positioning stop having to be exchanged or adjusted.
  • the punched holes which are lowered during punching, are held down after the holes have been made and the perforated workpiece is held in position until position-dependent work has been carried out elsewhere on the workpiece. This saves the time that would otherwise be required for a second alignment process. In addition, tolerances that could be caused by a second alignment process are avoided. Depending on the positioning once achieved, automatic parts feeding and fast attachment of hardware components can be achieved or simplified. As a result of the punching device located within a frame, machining operations can be carried out from the outside that are not hindered by the punching device.
  • a punching device 0 with four punch units I to IV is arranged above a support table 1.
  • Fig. 2 shows that the four punch units I to IV on a deck common to all units I to IV plate 17 are arranged, which are supported by a spacer 7 on a base plate 6, which is embedded flush in the support table 1. Between the cover plate 17 and the base plate 6 or the support table 1 there is free space 20, in which, according to FIG. 2, a plastic hollow profile bar of a window frame or a workpiece 3 is inserted for processing. From Fig. 1 it can be seen that the workpiece 3 has an opening or an inner contour that exceeds the horizontal outer contour, so that the workpiece 3 or the frame with its opening on the punching device 0 placed on the support table 1 and on this in the respective processing positions can be pushed on one positioning stop 9 or on several positioning stops.
  • the positioning stopper 9 is located as shown in FIGS. 2 on a plate 9 'which is arranged between the cover plate 17 and the spacer 7 in the special design of the perforating device.
  • the stop 9 or the two stop surfaces 23 shown in FIG. 4 determine the exact position of the workpiece 3, z. B. the positioning position shown in Fig. With solid lines.
  • the arrangement of the frame or workpiece 3 is carried out according to FIG. 2 so that only its surface 25 abuts the stop plate 9 'and the other frame surfaces are free from the spacer 7 or spaced apart. This results in an always exact arrangement of the punch 8 relative to the workpiece 3 via the dimension 26, which is always determined from the inner edge of the frame. For different dimensions 26 or distances of the punch 8 from the plate 9 ', this can be replaced or set.
  • the structure of the punching device can be seen in more detail in FIGS. 2, 3.
  • the punching device 0 has several punching units I to IV, each with separate punch drives 2.
  • a punch drive 2 essentially consists of a piston-cylinder drive 10 provided with compressed air connections 18, which is carried by a frame 5, which in turn is rigidly attached to the cover plate 17.
  • the several stamp drives 2 common cover plate 17 rests on the stop plate 9 'or the spacer 7, which is centered on the base plate 6 via cylindrical pins 28. With a bore 29 penetrating the base plate 6, the spacer 7, the stop plate 9 and the cover plate 17, this assembly can be clamped together and / or attached to the support table 1.
  • the cover plate 17 has recesses 27 through which stamps 8 pass.
  • Two stamp groups 29, 30 are shown, the stamps 8 of which are each held in the stamp holding plate 16.
  • the stamps 8 have a head 31 which engages in a correspondingly shaped, not designated recess in the stamp holding plate 16, so that slipping through to the workpiece 3 is not possible.
  • Above the stamp holding plate 16 there is a hardened pressure plate 15 with which the stamps 8 are acted upon when punching. This is itself driven by a holding plate 14 which is connected to a piston rod 32 of the piston cylinder drive 10. All three plates 14 to 16 are screwed together and sit on a guide bush 33, which is pushed in Fig.
  • Each guide sleeve 33 is slidable on a guide column 12 which is at one end with the deck plate 17 and at the other end with a cylinder holding plate 11 is rigidly connected.
  • the rigid frame 5 is formed, on the guide columns 12 of which the plates 14 to 16 are vertically displaceable.
  • the base plate 6 has a hole 34, protrudes in the vicinity of the spacer 7 by a Position istsanschlag- G Conference button 22 which thereby locks the drive hole.
  • the piston-cylinder drive 10 is not effective with such a lock despite the usual command. It is only possible to take effect when the workpiece 3 is in the correct position for punching and has actuated the button 22.
  • the frame or handlebar bearing part 39 to be fastened requires six holes 24 of the same size, which are produced by the appropriately dimensioned punch ends 8 ', which are of different lengths to reduce the instantaneous punching force or to distribute the punching force over successive periods of time.
  • a corner bracket 40 is shown in dashed lines, the holes 24 of which are made with the punch 8 of the punch group 29. Of the punch 8, only a few are provided with comparatively thin punch ends 8 ', which produce fastening holes for screw engagement. The holes 8, which are comparatively thick at their ends, are used to produce pin engagement holes.
  • the punching units I to IV serve to simplify the production of several groups of holes on a frame 3.
  • the punching unit I produces the holes 24 for fastening a frame bearing part of a frame for a left-handed stop.
  • the punch unit II can make corresponding holes for a frame for a right-hand stop. If the workpiece 3 is pushed into the dashed position 3 'against the stop surfaces 23' of the stop plate 9 'shown in FIG. 4 below, the holes 24 for attaching a corner bearing for a left stop can be made, while corresponding holes for a through the punch unit IV Corner bearings for right hinges are manufactured.
  • the positioning of the workpiece 3 on the stops 9 or on the stop plate 9 ' is used to carry out further positioning-dependent work on the workpiece 3, that is from the outside, that is to say from the outside of the support table 1 and through the punching device is easily accessible undisturbed.
  • the punch 8 is held in engagement with the workpiece 3 after punching, so that the positioning position is guaranteed for other work. Loads occurring during this work can be easily taken over by the punch 8.
  • operations are possible in which an automatic parts feed takes place, e.g. B. the automatic feeding of the upper frame bearing parts, while the holes 24 are made for the corner bearing attachment. Plastering, welding or additional drilling work is also possible, depending on the location of holes previously made.
  • the punching device 0 has a positioning slide 40 which, for. B. from one on the Cover plate 17 in only one direction is longitudinally displaceable guide rod 40 'and a holder 40 "on which a stop gauge 42 is arranged, for example for locking parts of the frame.
  • the distance between such locking parts is usually measured starting from the frame surface 43, which on the horizontal stop surface 23 of the stop plate 9 'and is therefore defined
  • the positioned stop jig 42 receives, for example, the locking parts and these can be fastened to the right frame leg 44.
  • the punching device can also be designed so that a clamping process takes place with a special clamping element, so that the punch is relieved.
  • This tensioning element can be controlled as a function of the actuation state of the piston-cylinder drive 10.
  • the support table 1 is designed as a roller table.
  • a plurality of conveyor rollers 45 allow the workpiece 3 or the frame to be moved effortlessly in the direction of the arrows 46.
  • a welding system 48 is arranged on the support table 1, with which the individual frame posts are welded together in a manner known per se to form the workpiece 3 or the frame.
  • tables 1 are punch groups III, IV and I, II existing unit groups 49, 50 arranged at a distance from each other that is greater than the largest frame side length of the workpiece 3.
  • An operator station 51 is arranged between the two unit groups 49, 50.
  • the punching units III, IV and I, II are each arranged at right angles to one another and have the same functions as the corresponding punching units of FIG. 1. Accordingly, the corner bearing perforation will take place through the unit group 49, while the handlebar bearing perforation will take place through the unit group 50.
  • the workpiece 3 lies on two stops 52, on which it is connected with a e.g. pneumatically operated clamping unit 53 is held in a predetermined position.
  • the horizontal row of holes 24 is used to fasten a corner bearing for a DIN right stop, while the vertical group 37 of holes 24 is used for fastening a corner bearing for a DIN left stop.
  • the illustration in FIG. 5 shows, at the bottom right, a horizontal row of holes 24 for fastening a handlebar bearing for a DIN right stop, while the vertical group 36 of holes 24 serves for fastening a handlebar bearing for a DIN left stop.
  • the groups of holes can each be produced at the correct location on the workpiece 3, it must be arranged and moved either according to FIG. 5 or according to FIG. 6. This is how it is done when machining a DIN right workpiece 3 conditions that the frame coming from the welding system 48 is first arranged according to the position shown in solid lines in FIG. 5. After the adjustment of the workpiece 3, the punch unit IV or possibly a drilling unit is actuated. The workpiece 3 is then moved in the direction of the arrow 53 until it is in the position shown in dashed lines in FIG. 5, that is to say in the correct assignment to the unit groups 50. The punching unit II is then actuated by this and the punching unit shown in FIG 5. Horizontal group of holes 24 shown at the bottom left.
  • the workpiece 3 does not need to be lifted, but can be brought into the required processing position by simply moving it and rotating it as necessary.
  • the workpiece 3 also does not need to be raised in order to be brought into the working area of the device according to the invention.
  • FIG. 7 which manages with a single unit group 54 in order to produce the hole groups 36, 37 for corner bearing and handlebar bearing attachment of a DIN left frame, but also the corresponding hole groups for DIN right-hinged.
