  • the invention relates to the genus according to a device for molding end beads on tubular workpieces made of sheet metal, with paired beading rollers and with a contact surface for the workpiece to be machined, the beading rollers being rotatably mounted on the contact surface with an axis of rotation orthogonal to the contact surface and being motor-driven .
  • - Pre-shaped sheet metal jacket parts for cladding thermal insulation materials, in particular on pipes, are particularly suitable as workpieces.
  • the device is suitable for processing pipe fittings and segments that can be assembled into bends. If the corrugated sheet metal jacket parts are mounted on the outside of a thermally insulated pipe, the corrugations of the sheet metal jacket parts interlock and prevent the entry of dirt and moisture.
  • the contact surface of the device is aligned vertically.
  • the workpiece clamped between the bead rolls must be held and guided manually during the machining process.
  • the handling of the known device requires experience of the operating personnel. There is a considerable risk of injury when handling the sharp-edged sheet metal parts. Finally, the operating speed of the device is in need of improvement.
  • the invention has for its object to further develop a generic device so that a high processing speed can be achieved with simple handling.
  • the invention teaches that the contact surface is aligned horizontally and forms a support table for the workpiece, that a vertically movable pressure device with at least one pressure element is arranged above the support table, which lies under the weight of the pressure device on the upper edge of the workpiece, and that at least one support roller which can be placed on the lateral surface of the workpiece to be machined and whose distance from the pair of beads is adjustable is arranged on the contact surface on both sides of the pair of beads.
  • the pressure device has a gallows-shaped swivel arm with a vertically, vertically movable swivel axis and with a cantilever arm connected to the swivel axis by a sliding seat, and that a press-on element is rotatably and pivotably connected to the cantilever arm, which can be fixed on the workpiece is.
  • the pressure element that is firmly attached to the workpiece is carried along by the rotational movement of the workpiece and executes a rotary movement. Due to the pivoting mobility, the pressure element can be adapted to the inclination of the top face of the workpiece.
  • the invention teaches that the pressure element is designed as a bar with stop blocks which can be moved thereon and which grip the workpiece on the outside and is connected to the cantilever arm of the pressure device by means of a cardan joint.
  • the pressure device has a vertically movable cross-beam and two tubes rotatably held on the cross-beam, the tubes extending parallel to the support table and forming pressure elements which can be set in rotation by the workpiece rotating during processing .
  • the tubes only rest on one edge of the workpiece.
  • the distance between the tubes should be adjustable to allow the processing of workpieces with different diameters.
  • a structurally preferred embodiment of the invention provides that the tubes are mounted on sliding shoes which can be displaced on the crossbar.
  • the length of the pipes should also be able to be influenced.
  • the tubes are therefore expediently designed as telescopic tubes or axially displaceable in the bearing point.
  • the pressure elements lie under the weight of the pressure device on the upper edge of the workpiece. An easier and less unhindered workpiece change is possible if the pressure device is connected to a pneumatic one or hydraulically operated lifting device and is therefore vertically adjustable for the purpose of workpiece change.
  • the invention teaches that the support rollers are arranged on axially adjustable feed elements. A pair of support rollers can be adjusted to the machining gap of the pair of beading rollers, the arrangement expediently being such that the adjustment movement takes place at right angles to the connecting line between the axes of rotation of the beading rollers. A particularly good support function is achieved when the support rollers are positioned close to the engagement area of the beading rollers.
  • additional support rollers can be provided on the support table, at equidistant intervals. It goes without saying that these additional support rollers are also arranged on axially adjustable feed elements.
  • a further advantageous embodiment of the device according to the invention is characterized in that the pressure device comprises interchangeable weights. By selecting suitable weights, the contact force of the pressure device can be adapted to the workpiece.
  • the device according to the invention is characterized by simple handling. Manual guidance of the workpiece during workpiece machining is not necessary even with larger workpiece diameters. With the device according to the invention, pipe fittings and segments of different geometry can be processed in rapid succession. The device is therefore particularly suitable for locksmith work that must be carried out on the construction site.
  • the device shown in the figures is intended for forming and beading at the end on tubular workpieces made of sheet metal. These workpieces are, in particular, preformed sheet metal parts from which cladding for thermal insulation on pipes is produced. Especially straight pieces and segments that can be assembled into pipe bends come into consideration.
  • the basic structure of the device includes a contact surface 1 for the workpiece 2 to be machined and paired bead rolls 3, which are rotatably mounted on the contact surface 1 with an axis of rotation 4 orthogonal to the contact surface and can be driven by a drive device, not shown.

  • the cantilever arm 6 of the pressure device is connected at right angles to the pivot axis 9 and connected to it by a sliding seat 11.
  • Cantilever arm 6 and pivot axis 9 form a gallows-shaped pivot arm.
  • the pressure device 5 rests exclusively on the workpiece 2 to be machined under its own weight.
  • Directional arrows indicate that the pressure device 5 can perform adjustment movements in the plane and thereby follow the workpiece movements.
  • a cardan joint 12 is arranged between the cantilever arm 6 of the pressure device and the pressure element 7.
  • the pressure element 7 as a bar with it displaceable stop blocks 13 is formed.
  • the stop blocks 13 can be locked in the holding position by clamping screws 14 on the bar 7 and lie on the outside against the workpiece 2 to be machined.
  • the pressure element 7 follows the rotational movement of the workpiece 2 during workpiece machining.
  • FIGS. 1 and 3 A comparative view of FIGS. 1 and 3 shows that the support rollers 8 are arranged on axially adjustable feed elements 15.
  • the feed elements 15 are axially adjustable at right angles to the connecting line 16 between the axes of rotation 4 of the pair of beads 3.
  • the feed elements 15 are designed as strip-shaped components which can be fixed on the support table 1 by means of clamping screws.
  • the pressure device 5 arranged above the horizontal support table 1 has a vertically movable crossbar 17 and two tubes 18 which are rotatably held on the crossbar.
