Definitions

  • the invention relates to a device for processing the contact surface of a negative mold for a manhole bottom forming, optionally composed of profile pieces mold profile made of thermoplastic foam, which is provided with a machining allowance in the landing area, with a table for receiving the mold profile to be machined and a heating wire extending according to the cross-sectional profile of the contact surface to be produced, which is movable relative to the table along the contact surface to be machined.
  • the manhole bottoms are often made with a rough bottom without flume in an existing cup-like core and a shell shape, so that the flume subsequently according to the particular sewer guide by hand can be shaped.
  • at least the gutter branches opening into the main gutter can be made by means of profile pieces which are attached to the bottom of the molding core as negative molds of the guttering and to the profile strand formed by the mandrel for the main gutter connect.
  • the profile pieces for the gutter branches of a thermoplastic material to cut the pads of these profile pieces with a corresponding contour contour of the profile strand for the main channel shaped heating wire along a with the axis of the profile strand for the Main chute coinciding path is moved relative to the aligned profile piece, wherein it should be ensured that the plane of the heating wire is always aligned perpendicular to the axis of the profile strand for the main chute.
  • the heating wire covers an envelope surface, which corresponds to the surface of the profile strand in the connection region of the Gerinneastes.
  • the shape profile for the shaft floor channel can therefore be relatively easily assembled by a profile strand for the main channel and this profiled strand form-fitting subsequent profile pieces for the channel branches.
  • the prepared in this way shape profile for the manhole bottom receiving bottom of the mold core, which forms the subsequent occurrence surface of the shaft bottom, has for this purpose a flat contact surface for the mold profile, which optionally drops against the channel flow out.
  • Such flat landing surfaces of the shaft bottom entail the risk that wastewater residues on the tread surface will not flow off to the bottom of the shaft.
  • the tread surfaces of shaft bottoms are cone-shaped, so that wastewater residues flow towards the bottom towards the gutter.
  • To form such conical contact surfaces only the Formkem needs to be provided with a corresponding conical bottom.
  • a conical Kem convinced brings difficulties when a negative profile of the subsequent channel resulting profile shape to be placed positively on the bottom of the mold.
  • thermoplastic foam blocks For processing of thermoplastic foam blocks it is already known ( FR 2 754 208 ) to provide a clamped in a bracket heating wire which is rotatably mounted about three mutually perpendicular axes on an arm of a robot. Since the robot arm itself is pivotable about a horizontal axis and can be rotated with the frame of the robot about a vertical axis, the heating wire can be kept in any spatial position. With the help of a guided in such a type of heating wire thus supported on a turntable thermoplastic foam block can be processed to a rotating body with a jacket formed from straight generatrix and consequently also in the form of cones, but not to a workpiece with a conical recess.
  • the invention is therefore based on the object, a device for processing the contact surface of a molded profile made of thermoplastic foam of the type described in such a way that with simple means of a conical bottom surface of the mandrel corresponding contact surface of the mold profile is obtained.
  • the invention solves the problem set by the fact that the mold profile coaxial with the seating surface receiving table is rotatable about the receiving axis relative to the heating wire, which extends starting from a support in the receiving axis at one of the machined tapered contact surface corresponding angle to the receiving axis, and that the table has a passage for the relative to the table in the direction of the receiving axis in the machining allowance of the mold profile piercing heating wire.
  • a conical surface has straight generatrices, such a conical surface can be machined by a straight filament that is rotated about the axis of the conical surface relative to the thermoplastic foam workpiece.
  • molded profiles to be machined there is the difficulty that these shape profiles can be recorded with a precise position of a table only with their contact surface, so that the surface to be machined is not freely accessible.
  • the table is provided with a passage for the relative to the table in the direction of the conical axis coinciding with the receiving axis of the mold profile displaceable heating wire, thus, before the processing of the contact surface by a relative movement of the heating wire relative to the table in the direction of the recording axis in the machining allowance of the mold profile must penetrate to achieve a predetermined starting position for the actual processing of the contact surface. Since due to the melting process during the relative rotation of the heating wire relative to the mold profile only small circumferential forces are exerted on the mold profile, it requires no separate support of the mold profile during processing of the contact surface. It is only necessary to ensure that the mold profile is aligned with respect to the axis of rotation of the table on the table, so that the receiving axis is coaxial with the axis of rotation of the contact surface.
  • the heating wire on diametrically opposite sides of the receiving axis may have two branches symmetrical to the receiving axis, so that a relative rotation of 180 ° sufficient for a complete processing of the contact surface.
  • the heating wire can be supported in a simple manner via a mandrel coaxial with the receiving axis, which results in particularly simple electrical connection conditions, because yes the Schudrahtenden are freely accessible.
  • the heating power of the guided over the mandrel heating wire is sufficient to ensure the puncture of the heating wire in the machining allowance of the mold profile in the Domausstützung.
  • the tip of the mandrel for supporting the heating wire can be enclosed by a heating wire bow extending transversely to the heating wire, which provides for expansion of the parting line in the area of the mandrel.
  • the mandrel can finally be adjusted in the direction of the receiving axis, so that coincides with the adjustment of the dome of the inclination angle of Schudrahtcorrecte changed.
  • the channels are deeper than the channels. This can be taken into account by a corresponding inclination of the cone axis of the tread surface against the channel course.
  • Such an additionally inclined contact surface of the shaft bottom requires a correspondingly inclined, conical bottom surface of the shaped core, which in turn results in an adaptation of the contact surface of the molded profile.
  • the table may be about a transverse axis to the receiving axis are mounted pivotally adjustable so that the additional inclination of the conical surface of the shaft bottom can be simulated on the pivoting adjustment of the table. Due to the inclination of the recording axis, however, the recording axis is no longer consistent with the axis of rotation of the table.
  • the shape profile can be adapted to the diameter of the cylindrical mandrel can, by at least one additional, parallel to the receiving axis heating wire, which is held in a radially engageable to the receiving axis to the table and rotatable relative to the table about the receiving axis carrier provided be that the outer end faces of the mold profile lie in a diameter corresponding to the diameter of the shaped cylindrical surface. If a heating wire provided with diametrically opposite sides of the receiving axis branches for processing the contact surface, it is advisable to provide two diametrically opposite each other with respect to the receiving axis heating wires to achieve half a table circulation complete processing of the mold profile.
  • the device shown for processing the contact surface 1 of a molded profile 2 made of thermoplastic foam as a negative mold for a shaft bottom channel has a frame 3, which carries a receiving table 4.
  • This shooting table 4 is mounted on a turntable 5, which rests on a support plate 6 on guide carriage 7.

  • the turntable 5 carries two side cheeks 13, on which the table 4 is articulated about the pivot axis 12, with the help of the side cheeks 13 encompassing webs 14.
  • the pivot axis 12 opposite ends of the webs 14 through an axis 15th connected to each other, on which a arranged between the side walls 13 pivot drive 16 engages.
  • the table 4 can be adjusted in its inclination by an actuation of the pivot drive 16, for example in the form of a spindle drive.
  • arms 17 are provided for bracing a heating wire 18, which is supported between the end brackets 19 on a pin 5 coaxial with the turntable 5 and two symmetrical branches 21 forms to the mandrel 20, which intersect in the axis of the turntable 5.
