Definitions

  • the invention relates to a method and apparatus for preserving the cavities of workpieces with a molten material, e.g. Wax, and is particularly suitable for cavity preservation of vehicle bodies.
  • a molten material e.g. Wax
  • Such a preservation system is e.g. in EP 0 003 223 A1.
  • molten preservative e.g. Wax
  • molten preservative e.g. Wax
  • flooded in large quantities in the bottom region of the workpieces e flood holes flooded into the cavities of the workpieces and discharged again after a residence time through said flood holes.
  • a preservation plant Dürr GmbH according to the preamble of claim 6 has become known by a public prior use at Völkswagen AG in 1995.
  • the object of the invention is therefore to provide a method for preserving the cavities of Maschinenstükken, in particular for the cavity preservation of vehicle bodies, which has simpler maintenance conditions, lower maintenance costs and lower susceptibility, and variable for different workpiece sizes and shapes can be used, and therefor to develop a system that can be produced with little technical and economic effort.
  • the object is achieved by a method according to claim 1 or 2.
  • the first advantageous embodiment of the invention is characterized by an adapter frame in the modular principle.
  • the frame 10 is assembled with standard construction profiles 11-14 and corresponding assemblies. In exceptional cases, additionally individually adapted components 18, 15, 16, 17 ... can be manufactured and screwed.
  • the frame 10 can be optimally tuned to the vehicle (e.g., pneumatic elements) due to the large number of available components. Furthermore, the frame 10 can be adapted to the environmental conditions (e.g., cover profiles). The required accuracy with centering guides and other centering aids is provided by the system.
  • the frame 10 is relatively lightweight, thus resulting in a low warm-up time and uniform heating.
  • Old frames need not be scrapped when a model is changed, but can be dismantled and adapted for new models.
  • the first installation and the respective flood frame 10 will be explained in more detail below with reference to FIGS. 1 to 5.
  • the flood area 4 is optionally a cooling area 5 and / or a follow-up and control area 7 downstream.
  • the flood area 4 is arranged outside the latter 4 arranged and movable robot 9 o.
  • Handling technology which engages with a, partially flexible and directly heatable supply lines 22a and 22b holding arm 9a in the flood area 4 and
  • a movable flood frame 10 for selectively coupling the supply lines 22a and 22b with at least one connecting line 15 of the flood frame 10 engages below, and that also outside the flood region 4, the coupled to the supply lines 22a and 22b means 23 for processing and supply of the preservative is arranged
  • flood frame 10 is a longitudinally aligned, in several sections 19a ... 19n subdivided Andocksteg 18 is provided, above each of the latter 18 located at the end of the heated and flexible connecting lines 15 and supported on supports 13 and 14 coupling pieces 16 are arranged.
  • the other ends of the connecting lines 15 held in the sections 19a... 19n are formed at the level of the lower surface of the docking bar 18 in such a way that a detachable coupling with the supply lines 22a and 22b is possible.
  • the sections 19a... 19n are each designed to receive and hold 2 or 4 connecting lines
  • wax is used as a preservative.
  • the means 23 for preparation and supply of the preservative an intermediate storage container 24 with melting tower 25, a working container 26 and pumps for conveying the molten preservative, wherein between the working container 26 and the supply lines 22 a and 22 b with a an eccentric screw pump 27 equipped with a frequency-controlled motor is arranged
  • the wax supply systems are located substantially laterally below the plant. All wax-carrying piping and hoses are heated. The heating of the containers and hoses is done electrically.
  • Wax blocks are delivered. Long-term storage takes place in solid form.
  • the wax is manually fed to an electrically heated melting tower 25 in use, with the then-melting wax flowing into an intermediate storage vessel 24. This is also electrically heated and has a stirrer.
  • the wax supply is carried out by a working container 26 with stirrer and temperature control, level sensors and other safety devices.
  • the working container 26 can be pumped into the intermediate storage container 24.
  • the dosage is carried out with independent systems of identical construction.
  • An eccentric Schnekkenpumpe 27, which is located in the working container 26, is driven by a frequency-controlled motor, the metering (amount and pressure) is achieved via the engine control (see scheme wax flood plant).
  • a pressure and a quantity value are stored in the PLC via the operator panel 8.
  • the speed of the pump is controlled via control loops and frequency converter so that the respectively required delivery pressure is reached.
  • the required quantity is measured via a pulse generator and the pump is switched off when this value is reached.
  • FIGS. 9 to 11a to be described below is used to carry out the method according to claim 2. Also in this task according to the invention a structurally closed, temperable section 30, with spatially separated heating area 31 and flood area 32, and a ceiling conveyor 6 and a control unit 8 is used.
  • a reservoir 33 for the preservative K and the leading from the reservoir 33 to the second flood frame 40 conveying lines 34a, ... 34n are spatially integrated into the temperature-controlled second section 30.
  • the storage container 33 is now at least partially disposed directly under the heating area 31 and / or the flood area 32 and connected to the latter 31 and / or 32 by ventilation technology.
  • the second flood frame 40th arranged by means of brackets 41 stationary in the flood region 32 and can optionally, for example in a model change, be replaced.
  • each provided on the second flood frame 40 and with the flood holes WL 1 to WL 2 of the workpiece W coupling piece 16 ' is associated with a delivery line 34a, ... 34n, each with a positive displacement pump 35a, ... 35n , and that the second flood frame 40 longitudinal and transverse struts 11 'and 12', at least three receiving and clamping cylinder 17 'for the workpiece W, supports 13' and 14 'for securing the coupling pieces 16' and fittings 42, in which 42 each one of the conveying lines 34a, ... 34n is detachably connected, and each of the connecting pieces 42 with the coupling pieces 16 'connecting leads 43a, ... 43n has
  • a connector 42 can serve several leads and be equipped with a controllable valve.
  • each of at least on its front and rear front receiving and clamping cylinder 17 'for locking the workpiece W having flood frame 40 may be executed in a variable construction, such that substantially standard-compliant construction profiles for the longitudinal 11' and Cross struts 12 'as well as partially used for the supports 13' and 14 '.
  • the supports 14 and 14 ' are movable, pivotable, tiltable or rotatable.
