Definitions

  • the present invention relates to a guide device for positioning blanks for a forming tool.
  • Guide devices for positioning blanks are mainly used in automobile construction, in particular for the manufacture of body parts.
  • blanks that is to say flat metallic components or sheets
  • a forming tool in particular in a deep-drawing tool.
  • instructors which are usually essentially vertically upwardly aligned columns, each having an inclined positioning surface, so that a blank fed to the tool from above on its peripheral edge along the positioning surface in the desired position slides and is lowered into the forming tool.
  • instructors distributed around the forming tool are often used.
  • a forming tool with a plurality of adjustable guide from the WO 2016/150617 known.
  • a conventional device for positioning blanks or pressed parts consists of a guide which is rigidly connected to the tool and which can optionally also have a rocker.
  • Production-related fluctuations in the width of so-called “coils” from which The blanks are essentially obtained by trimming, or the fact that the coils do not enter the center leads to the fact that some blanks are in an inadequate or incorrect position in the drawing tool.
  • the tolerances increase by the number of welded parts of the blanks, which leads to even greater deviations.
  • various component defects such as drawing cracks etc. can occur, as well as further surface damage due to abrasion and chip formation.
  • these deviations have to be corrected manually, which leads to production stoppages.
  • the incorrectly positioned circuit board in the drawing tool can result in further irregularities in relation to the surface, trims and flanges.
  • a guide device for positioning blanks for a forming tool comprising a guide which has a beveled positioning surface, the positioning surface being designed so that a peripheral edge of a board can be positioned in a transverse direction by contact with the positioning surface, with the guide device comprises a housing module, wherein the guide is mounted in the housing module so as to be linearly displaceable in the transverse direction, the housing module having a spring system, the spring system preloading the guide in the transverse direction.
  • a guide device is not designed as a simple rigid component, but comprises two parts that can be linearly displaced relative to one another: on the one hand the guide in the narrower sense, on which the required positioning slope is formed, and on the other hand a housing module which is usually rigidly mounted on a forming tool .
  • the guide itself is slidably mounted in the housing module, with a spring system biasing the guide in one direction, the "transverse direction".
  • This transverse direction is the direction in which a board is usually moved through the positioning surface when the board is lowered.
  • the positioning surface is usually a surface that is inclined from top (thin) to bottom (thicker) in the installed position.
  • a guide can give in or retreat so that hard knocks from faulty or incorrectly prepositioned boards can be avoided and thus component and tool errors can be avoided.
  • Defective parts can also can be recognized and sorted out at an early stage after forming with the help of such guide devices.
  • the spring system preferably comprises a plunger aligned in the transverse direction, the plunger resting against or being attached to the guide, the plunger being acted upon with a predetermined force in the transverse direction in order to preload the guide in the transverse direction so that when a circuit board rests against the guide a force greater than the specified force, the ram is moved linearly against the transverse direction.
  • the spring system can in particular comprise a spring-loaded pressure piece.
  • the spring system therefore comprises, in one embodiment, a mechanical spring.
  • the spring system can comprise a pneumatically operated cylinder.
  • the spring system can therefore be designed pneumatically and use gas pressure to apply the preload or restoring force.
  • the guide preferably comprises a guide bracket and a receiving plate, the guide bracket having the positioning surface, wherein the receiving plate is designed to be linearly guided in the housing module.
  • either the mounting plate or the housing module comprises a linear groove which is arranged in the transverse direction
  • the other of the named parts i.e. the housing module or the mounting plate, comprises a cylinder pin, so that the cylinder pin is guided in the linear groove to guide the guide linearly in the To lead housing module.
  • the guide device preferably comprises a base plate, the housing module being fastened on the base plate, the receiving plate of the guide being arranged between the base plate and the housing module.
  • the guide can thus be housed in a two-part structure that can be rigidly attached to a forming tool, comprising a base plate that can be attached directly to the forming tool, and a housing module that is rigidly attached directly to the base plate and thus indirectly to a forming tool can.
  • the guide device preferably comprises a sensor which is set up to detect the positioning of a circuit board and which is or can be connected to control electronics in order to enable a forming process.
  • the sensor can in particular be an inductive sensor or a reed contact.
  • a forming tool can comprise at least one guide device for positioning blanks, which is designed as described above.
  • a conventional guide device or a conventional guide 11 or 21 is shown, which is not according to the invention.
  • the directors 11, 21 of the FIGS. 1 and 2 have a beveled positioning surface 12, 22, the positioning surface 12, 22 being designed so that a peripheral edge of a board can be positioned in a transverse direction Q by contact with the positioning surface 12, 22, that is to say that a guide 11, 21 from above placed board slides along the positioning surface 12, 22 during the lowering and is pushed in the transverse direction Q in order to position the board in the transverse direction Q in the desired manner.
  • the conventional guide 11, 21 are rigidly connected to a forming tool and can, for example, have a rocker 23, as in FIG Fig. 2 shown.
  • FIGS. 3 to 9 Referring devices according to the invention or their components are shown in more detail.
  • a guide device comprises a housing module 33, 43, 63, 73, 83, 93.
  • the guide 32, 42, 82, 92 is mounted in the housing module 33, 43, 63, 73, 83, 93 so as to be linearly displaceable in the transverse direction Q.
  • the housing module 33, 43, 63, 73, 83, 93 has a spring system on, for example a spring-loaded pressure piece 612 or a pneumatic cylinder 412, 712, 912, the spring system preloading the guide 32, 42, 82, 92 in the transverse direction Q.
  • a guide device has a resilient pressure piece 612, a base plate 38, 81 which is rigidly connected to the tool and pinned, a guide 32, 82, which is composed of the guide bracket 51, an intermediate block 52, a receiving plate 53 and a sliding element 511 is slidably mounted between the base plate 38, 81 and the housing module 33, 63, 83 with a resilient pressure piece 612. At the same time, this is secured in its guide via a cylindrical pin 611 which engages in a groove 56, 86 of the receiving plate 53.
  • the guide 32, 82 presses the board, using the spring pressure force that is produced, into a predetermined position.
  • the spring pressure force can be adapted to the respective product or tool.
  • An inductive sensor 811 which can optionally be installed in the base plate 38, 81, enables the deep-drawing process via a partial position control. Once this process has been completed, the guide 32, 82 slides back into its starting position due to the spring pressure force. Since errors in the deep-drawing process, such as cracks, waviness, trailing edges and sink marks also change the width of the drawing edge, the present invention can also be used to monitor this in the further production process and remove defective parts at an early stage From the system instead of at the end of a production line. For example, a pulling edge that is too wide triggers the tool lock and thus prevents the further production of components that are not in order.
  • a guide device has a pneumatically operated cylinder 412, 712, 912, a base plate 48, 91 which is rigidly connected to the tool and pinned, a guide 42, 92, which is composed of the guide bracket 51 , an intermediate block 52, a receiving plate 53 and a sliding element 511 is slidably mounted between the base plate 48, 91 and the housing module 43, 73, 93 with pneumatically operated cylinders 412, 712, 912 and is attached to the thread of the piston rod or the piston rod by means of two self-locking nuts 914. of the plunger 45, 75 is rigidly connected.
  • the guide 42, 92 is secured in its guide by means of a cylindrical pin 711 which engages in a groove 56, 96 in the receiving plate 53.
  • the guide 42, 92 When the board is inserted into the drawing tool, the guide 42, 92 is in its starting position, namely retracted. Shortly thereafter, this is pushed into the working position (extended) by means of the compressed air operated cylinder 412, 712, 912, which exerts a corresponding pressure force on the board via the guide 42, 92 and pushes it into a predetermined position. Via an optional reed contact 715 on the pneumatically operated cylinder 412, 712, 912, the adjusted end position of the board can be queried and the deep-drawing process released via the partial position control.
  • a guide device can be provided in modular design and comprise the following: a base plate 38, 48, 81, 91, which is rigidly connected to the forming tool and pinned, and can be equipped with an inductive sensor 811, a receiving plate 53, which is in Connection with a sliding element 511 enables the linear guidance of the guide 32, 42, 82, 92, a guide 32, 42, 82, 92, which, composed of a guide bracket 51 and an intermediate block 52, is rigidly connected to a receiving plate 53 and as a stop surface for the board or the component, as well as for positioning, a housing module 33, 43, 63, 73, 83, 93, optionally equipped with a spring-loaded pressure piece 612 or a pneumatically operated cylinder 412, 712, 912 around the board or the component to press with the guide 32, 42, 82, 92 in a predetermined position and at the same time also allows the guidance of the receiving plate 53, as well as the guide he 32, 42, 82,
  • the advantage of this invention is that defective components from the deep-drawing process are reduced and parts that are not flawless can be removed from the system at an early stage in the further production process.
  • the blanks are pressed to a predetermined position by the guide device in order to compensate for any deviations in the length or width of the blanks (for example up to 20 mm).
  • Due to the receding effect of the guide system, abrasion on the guide system or the formation of chips due to the incorrect position of the blank can be reduced, resulting in fewer rework parts leads.
  • the present invention can be used to identify defective parts at an early stage - through targeted monitoring of the drawing edge - and to remove them from the production process. This fact causes a further reduction in rework and scrap costs, as well as the workload and costs for checking certain problem areas of the component, subsequent sorting and customer complaints.
  • a guide device with a resilient pressure piece can comprise (see above all Fig. 8 ): a base plate 81 on which an inductive sensor 811 can optionally be installed in a groove provided for this purpose by means of a screw 812 and which is rigidly connected to the tool with two diagonally offset screws 813 and two diagonally offset cylinder pins 814; a guide 82, which is rigidly and non-rotatably composed of a guide bracket 51, an intermediate block 52 and a receiving plate 53 by means of a screw 512 and a cylinder pin 513 and is additionally secured with a screw 515 via a sliding element 511 fastened with two screws 514, 515; a housing module 83 in which a spring-loaded pressure piece 612 is installed, which guides the slidably mounted guide 82 between the base plate 81 and the housing module 83, secures it in its guide by means of a cylindrical pin 611 and which is rigidly connected to the base plate 81 with two diagonally offset screws 815.

  • the spring-loaded guide device can comprise housing modules 83, 93 which, depending on the requirements, can be equipped with a spring-loaded pressure piece 612 or with a pneumatically operated cylinder 712.
  • the sliding back property of this guide device favors the reduction of abrasion on the guide surfaces and thus the decimation of reworking parts from the deep-drawing process. Since the present invention compensates for irregularities from the production process of coils or blanks (for example up to 20 mm), scrap and rework costs from the deep-drawing process can be reduced can be decimated or even eliminated. In order to minimize further costs with regard to scrap, rework, sorting, workload, complaints and storage, the present invention can be introduced in further steps of the production process in order to monitor critical areas specifically by means of the drawing edge and thus prevent the production of defective parts.
