Definitions

  • Patent European 0 611 611 concerning an electrical device for bending tubes using a transmission system consisting of an electric reduction motor endless-crown, and comprising a shoe tree and a shaped shoe.
  • the transmission system operates by a gyratory movement the shaped pad around the shoe tree.
  • a cover Coaxial with the axis of rotation of the shaped shoe, a cover has been placed limit switch fitted with fixed stop means and plates with removable cleat, angularly arranged to stop when it rotates with the projection a rod sliding on the frame of the device. By its movement the rod moves the work control of the transmission.
  • the device for fixing the bending angle on the apparatus for bending tubes object of the present invention offers a new a more efficient and precise solution aimed at preselecting the angle of bending on bending devices of the type described. It is characterized by the fact that the shaped shoe (5), the cover (8), a graph crown (3) and a clamping means (4) are arranged co-axially with respect to the axis (9) of the shaped pad (5); the cover is provided with a cooperating threaded rim (83) with the clamping means (4); the angular skirt (10) has teeth lateral (81); the crown with graph (3) is provided with a lateral toothing (31) combined with the lateral toothing of the cover (8), and a working stop (t); and the working stop (t) remaining in a position desired by the user between the safety stops (11a, 11b).
  • Figure 1 is a vertical view of a bending apparatus tubes, without shoe tree or shoe, to which the device object of application the invention.
  • FIG. 2 is a plan view in plan of FIG. 1, including the shoe tree (6) and the shoe (5).
  • Figure 3 is a front view of the device object of the invention, positioned for a concrete angle (a) of bending (30 °).
  • Figure 4 is a rear view of the device object of the invention, positioned for the same bending angle (a) as in the figure anterior (30 °).
  • Figure 5 is an exploded perspective view of the components of the device which is the subject of the invention.
  • the crown causes the movement of the shoe (5), the shoe tree (6) remaining fixed.
  • the limit cover (8) has a wide skirt angular (10) whose ends serve as safety stops (11A), (11B) respectively for the rotation from work to work and for return to position initial, insofar as they will be embedded respectively in the outward journey and in the back, to a projection (12) fixed on a sliding rod (13) (FIG. 1) which actuates the device to start / stop the device.
  • the limit cover (8) has a threaded rim (83) for the coupling of the rest of the elements of the device.
  • the cover (8) has a conjugate toothing (81) to embed / undock with a toothing (31) of the graph crown (3) which includes a working stop (t).
  • the maximum working angle intervenes when the working stop (t) rests on the safety catch (11B) back and forth.
  • the crown graph (3) can rotate relative to the cover (8) and the working stop (t) which emerges from the graph crown (3) will be placed so that the angle of work ( ⁇ ) or that desired by the user, between the safety catches (11A), (11B), since said working stop (t) will be that which will be fitted with the projection (12) of the rod (13).
  • the auxiliary crown index (7) has on the periphery of a "V" protruding area (71) indicating the desired angle for bending the tube and fixing to the cover (8) by means of its tongue (72) in the groove (82) (grooved and tabbed).
  • the clamping washer (4) is screwed onto the flange (83) of the cover (8) and is used to attach / detach to all of the elements on the cover (8).
  • the crown (3) can be replaced by the angular graduated ring (a) and attached to said crown (3).
