Definitions

  • the invention relates to a belt sander for Grinding of tubes according to the generic term of Patent claim 1.
  • the disadvantage of this device is the increasing Wrap angle of the sanding belt around this working pipe increasing spring force, which in turn only by a corresponding increase in the contact pressure of the Bandes can be overcome to the pipe to be processed.
  • This has the consequence that the tube unilaterally with higher Contact pressure is applied by the abrasive belt and thereby in turn causes uneven grinding image.
  • Object of the present invention is to provide a Belt grinding machine, with low effort a wrap of about 180 degrees of a tube possible without significantly increasing it Drive power is required.
  • the drive unit 3 for example, an electric motor or a pneumatic motor is shown as a rectangle on the right side.
  • the supply line 5 Through the supply line 5, the corresponding energy (electricity or air) is supplied.
  • the drive unit 3 With a switch 7, the drive unit 3 can be switched on and off.
  • a driven pulley 9 At the front end of the drive unit 3 sits a driven pulley 9.
  • two pivot arms 11 and 13 are fixed to the drive unit 3, of which at least one is pivotally mounted about the rotation axis A in the vicinity of the driven pulley 9.
  • a handle 15 On firmly connected to the drive unit 3 arm 11 a handle 15 is further attached to which the operator holds the machine 1 with the second hand.
  • the pivot arm 13 is pushed away by a spreading spring 17 from the fixed arm 11 (arrow P).
  • deflecting wheels 19,21 At the ends of the two arms 11,13 deflecting wheels 19,21 are placed, which carry a circulating around these two pulleys 19,21 and the output roller 9 endless abras
  • the known grinding machine during of the grinding process i. between the two Umlenkmannn 19,21 wraps around the grinding belt 23 a tubular workpiece 25 at an angle beta of less as 180 °.
  • the wrap angle beta In relaxed state runs the run 26 of the Abrasive belt 23 tangentially from the deflection wheel 19 to the deflection wheel 21.
  • the wrap angle on the workpiece 25 is determined by the force F with which the Operator the belt grinder 1 against the Workpiece 25 presses, determined.
  • the first fixed, the guide wheel 19th supporting arm 11 may have a fixed length or, as in the example shown in Figures 2 and 3, as Teleskoparm be performed so that its length L, i. the distance of the axis of rotation of the roller 19 to the axis of rotation A of Output roller 9 and thus the distance to the deflection roller 21 for adaptation to the diameter D of the workpiece 25 is changeable.
  • the shortening takes place by the active pivoting of the pivot arm 13 with one hand of the operator counterclockwise about the axis of rotation of the guide wheel 29.
  • the guide wheel 21st consequently approaches the guide wheel 19 on one circular arc, which is only marginally of a Straight line deviates.
  • With increasing tilt angle of Schwenkarms 13 increases the angle between the Axle of the spring 17 and the toggle lever 33. This leads to a continuous decrease in the force of the spring 17 the pivot arm 13.
  • the tensile force remains the abrasive belt 23 is substantially unchanged and thereby the contact force in the entire looping area beta almost the same, regardless of whether the Diameter D of the workpiece is large or small.
  • Diameter D is the distance between the pulleys 19,21 already idling larger, accordingly is the Base distance for machining a smaller pipe (see Figure 3) already smaller before starting work.
  • the Setting the distance is done before the beginning of Processing.
  • the arrangement of the handle 15 on the pivotable arm 13 and also at the end of the boom 31 makes it possible to Pivoting movement of the arm 13 not only by the Relative movement of workpiece 25 to the machine. 1 but actively by the pivoting of the arm 13th to assist with the boom 31.

Claims (3)

  1. Machine à meuler à bande (1) pour le meulage de tubes (25), comprenant un organe d'entraínement (3) avec un rouleau de sortie (9) pour entraíner une bande de meulage (23) destinée à circuler sans fin, deux roues de renvoi (19, 21) disposées à distance du rouleau d'entraínement (9), dont l'une est disposée à l'extrémité d'un bras pivotant (13) pouvant pivoter autour d'un axe de rotation (A) en étant sollicité par ressort et dont l'autre est disposée à l'extrémité d'un premier bras (11) fixement relié à l'organe d'entraínement (3), et un ressort (17) agissant sur le bras pivotant (13) pour tendre la bande de meulage (23) et écarter le bras pivotant (13), caractérisée en ce qu'une console (31) faisant saillie vers l'extérieur est disposée sur le bras pivotant (13), console qui est dotée d'une poignée (15) au moyen de laquelle le bras pivotant (13) et la roue de renvoi (21) sur le bras pivotant (13) peuvent être rapprochés de la roue de renvoi (19), qui est montée à l'extrémité du bras (11) relié à l'organe d'entraínement (3).
  2. Machine à meuler à bande selon la revendication 1, caractérisée en ce que le ressort (17) agit sur un bras à genouillère (33) fixement assemblé au bras pivotant (13), le bras à genouillère (33) étant, avant le contact de la bande de meulage (23) avec la pièce travaillée (25), perpendiculaire à l'axe du ressort, de sorte qu'avec la progression du pivotement du bras pivotant (13) et la progression de l'enroulement de la bande de meulage (23) autour de la pièce travaillée (25), l'angle entre le bras à genouillère (33) et l'axe du ressort augmente, et par suite la force exercée par ressort (17) sur le bras pivotant (13) et l'effort de tension exercé sur la bande de meulage (23) diminuent.
  3. Machine à meuler à bande selon la revendication 1 ou 2, caractérisée en ce que la longueur (L) du premier bras fixe (11) en direction de la roue de renvoi (21) fixée sur le bras (13) pouvant être abaissé par pivotement peut être modifiée afin de régler et modifier la distance entre les deux roues de renvoi (19, 21).
