Definitions

  • the shoetree of the apparatus rotates, causing movement and curvature of the tube without it being planned, to date, to provide it with a device performing repetitive work , or to use any device that automatically stops the machine running.
  • This device is precisely what is the subject of this invention.
  • 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 device 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 switch 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 is locked by one end in the position desired by the user by conventional means, for example by a stud (15) to the 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 control working (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, 45 °, 99 ° or 135 °, on a repetitive modo, insofar as when one of the widgets makes abutment with this same piton (12) one stops the walking automatically , as 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-stroke cap (8 ') has been used in FIGS. 5 and 6, the skirts (101), (102) of which are angularly arranged so that the end (11) of the first skirt (101 ), 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 (112) abuts with the bolt (12), which is the neutral point for resumption of the cycle as described above. -above.
  • the stopping device could be a reverse gear.
  • the limit switch cap (8 ') and the disc (X) must be positioned and fixed between them as the user wishes.
  • a radial groove (r) has been made on the end-of-travel cap (8 ′) in which a screw (t) or any other embedding-tightening element of the disc can slide ( X) with the cap (8 '), but it would be possible to use some other conventional positioning-clamping solution.
  • 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.
