Definitions

  • the present invention relates to an electrical apparatus for bending tubes.
  • an electrical device for bending the tubes using a transmission system consisting of a motor-reducer electric motor which actuates a tower element constituted by a shoe tree or shaped shoe, said device comprising an end-of-stroke cap coaxial with the tower element and fixed abutment means, arranged angularly in two final positions for making a stop when the tower element is rotated with a stop, and means making it possible to stop the rotation of the lathe element when it reaches its final position.
  • the apparatus according to the invention is characterized in that it comprises stop means which can be fixed in determined angular positions on the end-of-stroke cap which is connected to the tower element to make a stop during a rotation of the lathe element with said stopper by limiting the stroke of the lathe element to determined angles, said stopper being fixed to a peg of a rod mounted to slide on the frame of the apparatus, said rod causing its movement the movement of the system work control of transmission.
  • Figure 1 is a vertical projection of the bending machine of the invention, not equipped with the shoe tree or the shoe.
  • Figure 2 is a plan view of Figure 1.
  • Figure 3 is a plan view of the end cap.
  • Figure 4 is a view of section A: A of Figure 1.
  • Figure 5 is a partial vertical view of another practical embodiment of the inventive bending machine.
  • Figure 6 is a side view of Figure 5.
  • the handle (1) of the bending machine has been placed in parallel with the longitudinal axis of the latter and above the axis of gravity in a horizontal position, so that it can be transported without risk of damage if the engine (2) is knocked against it, as this was likely to happen until then.
  • a transmission system consisting of a geared motor is used, which actuates the shoe / shoe tree, with a work control (7) forwards and backwards.
  • a limit stop cap (8) (fig. 3) arranged coaxially with the axis (9) of the device.
  • the end-of-travel cap (8) is provided with skirts (10) which are arranged angularly so that the end (11) of one of them serves as a stop for a peg (12) fixed to a rod (13) (figure 1) sliding.
  • the work control (7) ( Figure 4) is connected to a larget (14) which locks with one end in the position desired by the user by conventional means, for example by a stud (15) using a spring (16), and unlocks when the other end drives it (17) by the movement of the rod (13) with which it rotates on its axis (20) giving rise to the turn of the work control (7), which allows to stop walking.
  • a series of orifices (18) angularly staggered at distances fixed in advance have been placed on the end-of-travel cap (8) in order to place stop flanges (25) therewith the bolt (12) for bending the tubes of a determined angle, for example, 45o, 99o or 135o, on a repetitive modo, insofar as when one of the widgets makes stop with this same piton (12) one stops the walking automatically, as well as 'It is explained for the end (11) of the skirt (10).
  • the ends (11), (11 ') of the skirts (10) can act as safety stops in both directions of operation.
  • FIGS. 5 and 6 Another embodiment of the end-of-travel cap (8 ′) has been used in FIGS. 5 and 6, the skirts (10 1 ), (10 2 ) of which are angularly arranged so that the end (11 1 ) of the first skirt (10 1 ), when it abuts with a peg (12) fixed to the sliding rod (13), drives the latter by its movement by acting on a device for stopping walking.
  • the shoe tree in this position, returns to its initial position until the end (11 2 ) abuts with the bolt (12), which is the neutral point for resumption of the cycle as it has been ci -above.
  • the stopping device could be a reverse gear.
  • a disc (X) is provided coaxially provided with a radial tongue (l) whose radius (m 1 ) is of a length similar to that of the radius (m 2 ) of the cap (8 ').
  • the limit switch cap (8 ') and the disc (X) must be positioned and fixed between them as the user wishes.
  • a radial groove (r) in which can slide a screw (t) or any other element for clamping the disc (X) with the cap (8'), but it would possible to use some other conventional positioning-clamping solution.
  • the end (11 2 ) of the skirt (10 2 ) will continue to exercise the same function as that described above and the function of the end (11 1 ) of the skirt (10 1 ) will be replaced by the head (c) left, anticlockwise according to FIG. 5, of the tongue (l).
  • the head (c) relative to the stop (12) can form the desired angle at rest, or if you prefer, it will be possible to set the angle of curvature of the tube to be bent as desired.

Claims (4)

  1. Elektrovorrichtung zum Biegen von Rohren unter Einsatz eines Antriebssystems bestehend aus einem Elektro-Getriebemotor, der ein aus einem Profilgleitdom oder einer Profilgleitplatte bestehendes Drehelement (5) antreibt. Zu dieser Vorrichtung gehört eine Kappe (8;8') als Endlagenteil, die koaxial am Drehelement (5) befestigt ist und auf der die festen Endanschlagmittel (10, 11, 11',101, 102, 111, 112) in zwei winkligen Endstellungen angeordnet sind, um bei Umdrehung des Drehelements (5) auf einen Anschlag zu stossen, wobei den festen Endanschlägen ermöglicht wird, die Umdrehung des Drehelementes (5) zu stoppen, sobald die Endstellung erreicht ist, dadurch gekennzeichnet, dass sie die festen Anschlagteile (25;X) enthält, die in bestimmten Winkelstellungen auf der Endlagenkappe (8;8') befestigt werden können, die ihrerseits mit dem Drehelement (5) verbunden ist, um bei der Umdrehung des Drehelements (5) auf den genannten Anschlag zu stossen und den Hub des Drehelements (5) auf bestimmte Winkel zu begrenzen, wobei der genannte Anschlag am festen Bolzen (12) eines auf einer Gleitführung auf dem Gestell der Vorrichtung angeordneten Zapfens (13) befestigt ist. Der genannte Zapfen (13) löst durch seine Bewegung den Antrieb (7) des Antriebssystems aus.
