Definitions

  • the invention relates to a device for producing round tubes perforated in the lateral surface with a mandrel, which is supported at one end in the device and the other end of which the tube can be pushed on and which has a support element adapted to the tube inner shape in the punching area, one of which is external is assigned to the tube adjacent holding element through which a plurality of punches of a punching tool arranged along a surface line of the tube are passed, the punches having a common actuating element.
  • Such a device is known from US Pat. No. 3,538,735. It is a device which comprises four punching tools distributed over the circumference of the tube.
  • the tube can be pushed over a mandrel, which is adapted to the inner shape of the tube and also serves as a support element.
  • a holding element is arranged concentrically around this mandrel, leaving an annular gap for the pipe to be inserted, through which the stamps of the individual punching tools are passed.
  • the individual punching tools are actuated in that the punching tools have radially outwardly directed plungers which are in contact with straight-line control tracks which are arranged on the inside of a ring surrounding the punching tools.
  • This ring can be pivoted by means of a hydraulic cylinder, so that the tappets are pressed radially inwards when the tappet path is rolled over, as a result of which the punching process takes place.
  • the known device is relatively complex and inflexible.
  • the holding element forms a closed ring, so that practically the entire punching tools have to be exchanged for processing other tubes.
  • the present invention is therefore based on the object of providing a device of the type mentioned at the outset which enables economical production of perforated pipes of different sizes and hole patterns.
  • the mandrel is centered at both ends in the device and is flanked by two support elements arranged diametrically opposite one another with respect to the tube cross-section as a pressure mandrel, each support element being arranged in the interior of a guide half-shell open to the workpiece, which is arranged by the Holding element is formed, and that the actuating elements of the punching tools have workpiece-dependent activation bars for the optional use of the punches and can be actuated via a common feed drive.
  • the holding element is now in the form of guide half-shells, it can hold pipes of different diameters. Together with this, the design of the dome acts as a pressure mandrel, which enables the support elements to always be in contact even in the event of diameter deviations.
  • each support element is arranged inside a guide half-shell that is open towards the workpiece and is formed by the holding element, the guide half-shell supplements the support element.
  • the workpiece is located between these two parts. It is held in between.
  • the guide half-shells can be designed so that they are suitable for holding pipes of different cross-sectional shape and diameter.
  • the holding element supports the workpiece at least in the machining area, that is to say in the present case primarily along a pipe surface line.
  • the flat design of the holding element is sufficient for this.
  • its shape can also be adapted to the workpiece in such a way that it rests on the workpiece outside of the machining area.
  • the paired, diametrically opposite arrangement of the support elements and the associated punching tools offers the advantage that the punching forces act against each other, so that the support elements and the mandrel and any other parts that are subjected to forces during machining are not loaded on one side.
  • a uniform load also benefits that the mandrel is centered at both ends in the device. It is therefore secured against lateral displacement. Since the stamps are assigned a common actuating element, a uniform work attack of the punching tool is made possible.
  • the stamps can be used optionally via the activation bars without the need to switch off a drive.
  • the activation bars connect only those stamps to the actuating element that are actually to be used for the workpiece in question for processing.
  • Other stamps, which are present in the punching tool, but which are not used in the workpiece to be machined, are not linked to the actuating element by the activation bars and therefore do not take part in the machining. They remain on standby. With the device according to the invention, large conversions of the device can therefore be produced in the simplest way, in various sizes, with different hole patterns.
  • DE-OS-26 32 713 also shows and describes a device for punching holes in hollow profiles.
  • This device has a support element which can be brought into contact with the inner wall of the hollow profile with the aid of a dome.
  • the creation of the Support element is achieved in that two actuating tubes are moved against each other, whereby the mandrel and the support element brace.
  • That device differs from the device according to the invention in that only one punching device is provided. Only one support element is also provided, a holding element and a centering of the mandrel on both sides being missing. The mandrel is rather held by the hollow profile itself in the manner of a floating bearing.
  • a likewise cup-shaped object is arranged on a vertically oriented mandrel.
  • a punching tool for punching is arranged on the left of the cup-shaped workpiece, while a side slot stamp is provided on the right. Both tools are operated via a common drive.
  • the mandrel is not designed as a mandrel. Rather, the workpiece is held by a center punch, which drills the cup-shaped workpiece. The mandrel is also only clamped on one side.
  • a holding element designed as a guide half-shell is not provided.
  • the support element is designed as a die containing a hole pattern.
  • the hole pattern can either have a predetermined hole pattern depending on the workpiece or be in the form of a surface pattern that contains all possible hole positions.
  • the design of the support element as a perforated die facilitates the punching process. The punch waste can be pushed through the die.
  • each support element has a sawtooth-like inner surface, which is assigned a sawtooth-like, outwardly directed counter surface on the pressing mandrel. If you move the pressure mandrel relative to the support element, the opposing saw teeth of the support element and the pressure mandrel run against each other.
  • each support element is pressed radially outward against the pipe to be machined during an axial movement of the mandrel.
  • the loosening takes place in the other order, in that the saw teeth slide away from each other and the support element can thereby move away from the workpiece.
  • a simple mounting of the support elements results from the fact that they are held at the upper end of the respective guide half-shell. In this way, the workpieces can be inserted from below between the support elements and the guide half-shells.
  • the guide half-shells are provided with guide bores for receiving the stamps. Since the guide half-shells are arranged directly next to the workpiece during machining, they are able to hold and guide the punches of the punching tool exactly.
  • the actuating elements of two or more punching tools have a common feed drive.
  • the feed drive comprises two sliding wedges flanking the punching tools, to which counter-wedges are assigned on the drive side.
  • the counter wedges advantageously have a common yoke acted upon by an actuator.
  • the actuator can effect the feed centrally. An uneven movement of the punching tools is avoided.
  • spacer blocks can be provided between the guide half-shells assigned to one another.
  • the spacer blocks are used for the unchangeable mutual positioning of the guide half-shells. They define the free space between the guide half-shells arranged opposite one another. It can be easily adapted to different workpieces by selecting the spacer blocks.
  • the aim of the coordination can be that when the guide half-shells are placed on the spacer blocks, the workpieces between the guide half-shells are kept free of deformation but also free of play.
  • the spacer blocks are centered by turning them on guide columns, so that the guide half-shells also take an exactly central position during the punching process. This avoids off-center loads on the mandrel.
  • a lifting table which has workpiece receptacles which can be rotated about a vertical axis.
  • the lifting table enables the workpieces to be inserted from below between the support elements and the guide half-shells. In the ready position, it can easily be fitted with new prefabricated pipe sections. Automatic assembly is also possible.
  • the lifting table is raised together with the workpieces, with the possibility advantageously being given to raise the workpieces for the machining to different extents in order to offset the height of the holes of one surface line relative to the holes of adjacent surface lines.
  • the rotary mounting of the receptacles allows the workpieces to be rotated individually or together step by step after punching a vertical row of holes in order to punch further rows of holes.
  • the receptacles For the mutual alignment of the receptacles with the mandrel, it is provided that the receptacles have a centering opening for the mandrel. The centering takes place when the lifting table is raised.
  • the device 1 according to the invention is used to manufacture pipes perforated in the lateral surface, in particular silencer pipes.
  • the drill is formed from sheet metal outside the device and then welded along a connecting edge.
  • the invention can also accommodate seamless tubes. In any case, the tubes for processing in the device according to the invention have already been cut to length.
  • the device has an L-shaped frame 2.
  • the device shown is designed as a multiple punching device for pipes.
  • the punching tools are held in a holder 5, which is arranged at the upper end of the vertical L-leg of the frame. It spans the free space of the L-shape and protrudes slightly beyond the horizontal L-leg.
  • a lifting table 6 is arranged below the holder 5 and has three receptacles 7 for workpieces 8 arranged in a line one behind the other.
  • the workpieces consist of three sections of a cylinder tube of equal length. They are kept strictly vertical in the recordings 7. The details of the lifting table and the recordings will be discussed later.
  • the lifting table can be moved up and down along two vertical guides 9, which extend parallel to the L-leg of the frame and are arranged on the frame at a constant mutual distance from one another.
  • the punching tools 3 are arranged in pairs in the device. This can be seen particularly clearly from FIG. 3. Three processing stations 10, 11, 12 can be seen, each of which is equipped with two punching tools 3 lying opposite one another.
  • Each processing station is able to provide a workpiece, in the present case a cylindrical tube section 8 with a predetermined hole pattern, the hole patterns of the different workpieces not having to be identical to one another.
  • a mandrel 13 In the core of each processing station, a mandrel 13 is arranged, which protrudes upwards from each station and is supported there by means of adjusting devices 14 so that it can be raised and lowered on a cross member of the holder 5.
  • the mandrel has a circular cross section. Along the mandrel axis there is a central bore 15 which runs over the entire height of the mandrel and through which the punching waste falls downward, as will be explained below.
  • the vertically aligned mandrel 13 On its outside, the vertically aligned mandrel 13 has a sawtooth profile that has teeth that taper slightly downward. In the area of the teeth, the mandrel is provided with a slot 17 on the circumferential parts opposite the punching tools 3, in order to allow punches 16 of these tools or punching waste to penetrate the mandrel.
  • the mandrel forms a central actuating element for two supporting elements 18 arranged next to it, which flank it on opposite sides.
  • the support elements are designed as vertical strips and have an approximately rectangular cross section.
  • One side of the rectangle is designed as a semicircle and adapted to the inner wall of the workpiece to be machined.
  • the support elements 18 can be vertical Grooves of the mandrel must be stored. On their side of the rectangle facing the center of the mandrel, they have a sawtooth-like inner surface which corresponds to the sawtooth-like outer surface of the mandrel in such a way that the saw teeth of these two parts hook into one another. This means that the saw teeth of the support elements taper slightly upwards.
  • the support elements 18 serve as counterholders for the punching tools 3. If the mandrel is moved vertically downward, the saw teeth of the dome run against those of the support elements and press the support elements radially outward into contact with the pipe workpieces. In the device shown, the contact is made at least along the surface lines of the tube workpieces, into which holes are to be punched in accordance with a predetermined pattern.
  • the support elements 18 are diametrically opposite with respect to the tube cross section of the workpieces. They are each designed as a matrix containing a hole pattern.
  • the grid of holes contains a series of bores located one above the other, which are arranged at a predetermined distance from one another.
  • a pair of guide half-shells 19 are provided for fixing the workpieces on the outside, which have a U-shaped cross section, the opening of which is directed towards the workpiece.
  • the U-shape is matched to the diameter and cross-sectional shape of the largest workpiece. It encompasses such a workpiece.
  • the guide half-shells 19 can only. rest on the workpiece along the surface line that is also provided with the row of holes.
  • the guide half-shells have horizontal guide bores for receiving the punches 16 of the punching tools 3. Analogous to the hole pattern of the support elements, the guide bores are arranged vertically one above the other along a line and have the same mutual spacing as is present in the row of holes of the support elements.
  • the support elements 18 each have at their upper ends radially outwardly extending hooks 20 with which they are suspended in corresponding recesses in the guide half-shells. In this way, the support elements are mounted on the guide half-shells in a radially variable manner. This is necessary because there must be sufficient space between the support elements and the guide half-shells for moving the workpieces in and out.
  • the punches 19 of the punching tools 3 are arranged vertically one above the other, analogous to the bores of the support elements and the guide half-shells. They are aligned horizontally.
  • the stamps of each punch 3 extend radially outward from the corresponding guide half-shell to a common actuating element 21 which is formed as a vertical pressure bar.
  • the actuating element contains in each case a vertical activation bar 22 which connects predetermined stamps to the actuating element in a tensile and compressive manner.
  • the activation strips can be inserted from above into a groove of the actuating element and contain bores for the stamps not used for special machining, so that they are not acted upon when the actuating element is displaced horizontally.
  • FIG. 3 It can be seen from FIG. 3 that behind the actuating elements 21 arranged on one side of the axis of symmetry S of the machine frame there is a pressure plate 23 which extends over the entire height of the punching tools and in the horizontal direction over the ends of the three processing stations 10, 11 , 12 protrudes.
  • the pressure plate 23 therefore spans three punching tools 3 of the processing stations 10, 11, 12 located next to one another. This is done deliberately because one wants to achieve a uniform loading of the punching tools during feed.
  • a sliding wedge 25 which has a vertical wedge surface that is inclined so that the wedge tapers in the direction of the drive 24, is fastened to the outside of each pressure plate as the first intermediate member.
  • Opposing wedges are assigned to the sliding wedges as a second intermediate member, the inclined surface of which is in contact with the inclined wedge surface of the sliding wedge.
  • the counter wedges 26 are thus supported with the inclined surface on the sliding wedges, while they are in contact with the mounting plates 5 with the flat wedge surface.
  • the counter wedges are fastened at their thickened end to a common yoke 27 which is connected to the central drive 24 in a pull-resistant and thrust-resistant manner via a stroke adjustment element 27.
  • the stroke setting element is designed, for example, as a screw connection between the yoke and the punch of the feed drive and is used primarily to shift the stroke as a function of the workpieces to be machined.
  • tie rods 29 are connected to one another via, in the present case a total of eight, tie rods 29.
  • tie rods are located in a lower plane E1, which, as FIG. 4 shows, extends horizontally in the region of the lower ends of the punching tools 3.
  • tie rods are located in a plane E2, which is arranged analogously in the area of the upper end of the punching tools 3.
  • the sliding wedges 25 and the counter wedges 26 are arranged between the planes E1 and E2.
  • the tie rods are columnar.
  • the mounting plates 5 are anchored to pull and slide.
  • the columns serve for the storage of several parts, for example the pressure plates 23, which are displaceably supported by means of bushes 30 on the outermost columns of the upper and lower levels E1 and E2.
  • spacer blocks 31 are also held on the pillars symmetrically to the plane of symmetry S, which in the present case are designed in the form of strips and are immovably fixed in the said plane of symmetry on screwing in of the tie rods 29 (see partial section in FIG. 3 above).
  • the spacer blocks serve as stroke limiters for the guide half-shells 19.
  • the half-shells are connected to the actuating elements 21 via horizontal support rods 32. But the connection is not rigid.
  • the actuating elements can be moved for the actual punching stroke in the direction of the guide half-shells against the force of springs 33 which are clamped between the guide half-shells 19 on the one hand and the actuating elements 21 on the other.
  • the spacer blocks 31 project into the stroke area of the guide half-shell 19 and determine the position of the guide half-shells closest to the workpiece as a function of the workpiece during machining. In this way, deformation of the workpieces during punching is to be avoided.
  • the guide half-shells 19, the actuating elements 21 and the sliding wedges 25 are thus held in the horizontal direction on the tie rods 29 via the pressure plates 23.
  • FIGS. 1 and 2 it is shown in its lower ready position, in which the workpieces can be inserted into the receptacles 7 and removed from them again.
  • the lifting table 6 is in the processing position. It has moved all the way to the lower end of the punching tools and has inserted the tubular workpiece 8 so far between the support elements 20 and the guide half-shells 19 that the workpiece can be provided with the desired holes over its entire length.
  • the receptacles 7 each have a centering opening 34, into which the mandrel projects when the lifting table is in the processing position. He is held there against lateral displacement.
  • the receptacles have an opening which is coaxial with the through hole 15 and through which the punching waste falls downward.
  • FIG. 5 shows the rotary drive for the receptacles 7 of the lifting table 6 in a schematic manner.
  • the three receptacles are each rotatably mounted about vertical axes and are connected to one another by means of meshing gears 35, 36 and 37.
  • the middle receptacle is connected via a reduction gear 38 to a stepper motor, which is used to gradually rotate the workpieces for punching. Since only the bores of a surface line of the workpiece are punched out with each machining operation, the stepwise rotation of the receptacles can result in the entire surface of the workpiece being machined.
  • tubes are first formed from a sheet metal strip or a sheet metal blank of some kind and then welded to one another at the tube seam. They can then be cut to length.
  • a support element is inserted into the already welded pipe and pressed against the pipe. The punching takes place from the outside, the support element serving as a counter-holder for securing the workpiece and for absorbing the punching forces.
  • the tube is held vertically during the punching. If a force balance is desired, it is possible to punch the tube simultaneously from two opposite directions.
  • the workpieces for example the prefabricated tubes, regardless of whether with a seam or seamlessly, are inserted from above into the receptacles 7 of the lifting table 6 and clamped vertically there.
  • the lifting table is in the lower standby position shown in FIGS. 1 and 2. After clamping, the lifting table is moved vertically upwards, whereupon the workpieces are moved into the space between the support elements 20 and 19 as far up as is necessary for the desired machining.
  • the mandrel 13 is centered in a centering opening in the receptacles 7.
  • the mandrel 13 is displaced downwards for tensioning the support elements 20 with the aid of the actuators 14, whereupon the support elements are forced radially outward into contact with the workpieces due to the run-up of the saw teeth.
  • the drive presses the yoke 27 in the direction of the punching tools 3.
  • the counter wedges 30 run on the sliding wedges 25 and thus move the pressure plates 23 in the direction of the workpieces.
  • the actuating elements 21 are advanced in the direction of the workpieces 8.
  • the guide half-shells 19 move in the direction of the pipe to be punched and clamp it firmly on the support elements 20. At the same time, they come into contact with the spacer blocks 31, which serve as stroke limiters for the guide half-shells.
  • the distance between the actuating elements 21 and the guide half-shells 29 is reduced.
  • the springs in between are compressed. They are prestressed so far that they can absorb any unevenly occurring side forces and relieve the mandrel.
  • the punches provided for machining the workpiece are connected to the respective actuating element 21 in a tensile and shear-proof manner via the activation bar 22. Only they are pushed forward towards the workpiece and punch the desired holes out of the workpiece.
  • the stroke of the punching tools is dimensioned such that the punches penetrate into the mandrel and deliver the punching waste to the vertical through hole 15. The waste falls down through the receptacle 7 into the open.
  • the punch of the central feed drive 24 moves back together with the yoke 27 and the counter wedges 30.
  • the springs 33 supported on the guide half-shells fixed by the spacer blocks 31, are able to push back the actuating elements 21 and partially withdraw the punches from the workpieces, while the return stroke is generally carried out by the wedge drive.
  • the lifting table moves downward from the processing position shown in FIG. It releases the mandrel 13 at the same time.
  • the recordings detach from the workpieces, whereupon these can be removed.
  • the device according to the invention offers the manufacturer and customer the possibility of a short disposition. A quick tool change is possible even with different hole diameters. Different hole patterns can be achieved at any time by exchanging the activation bars 22.
  • the device is relatively small and requires relatively little investment, which means that even small quantities can be produced economically.
  • a decisive advantage of the invention is that the workpieces can be provided with holes over their entire circumference. Both longitudinally welded and seamless drawn tubes can be processed in various materials, especially aluminum.
