Definitions

  • the present invention relates to a fixture for supporting the part being treated, particularly for hide beveling machines and the like.
  • Conventional beveling machines for hides and the like generally have a cup-shaped blade in front of which there is provided a roller for moving the part to be treated which is arranged below a hide retaining shoe.
  • a movable guide In front of the shoe, with respect to the travel direction of the part being treated, a movable guide is provided having the purpose of guiding the edge of the hide that must be beveled by cutting, which usually assumes a sector-like shape wherein the cutting depth is greater towards the free edge and decreases towards the inside of the part.
  • the aim of the present invention is to solve the above problem by providing a fixture for supporting the part being treated, particularly for hide beveling machines and the like, which allows to support the hide up to the cutting blade, thus obtaining a treatment which is always precise.
  • a particular object of the invention is to provide a supporting fixture wherein it is possible to adjust at will and precisely both the cutting depth and the cutting width while the hide is always perfectly supported even in the case of soft or otherwise delicate hides.
  • Another object of the present invention is to provide a fixture for supporting the part being treated which, in view of its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
  • Another object of the present invention is to provide a supporting fixture which can be easily obtained starting from commonly commercially available elements and materials and is also competitive from a merely economical point of view.
  • a fixture for supporting the part being treated particularly for machines for beveling hides and the like, according to the present invention, comprising a roller for moving a part being treated and a front movable guide characterized, in that said roller is situated below a shoe which is arranged in front of a cup-shaped blade and in that the front movable guide is laterally adjacent to said shoe in the travel direction of the part being treated, said fixture further comprises a lateral movable guide which is arranged laterally adjacent to said shoe along a direction which is substantially perpendicular to the travel direction and ends substantially flush with said cup-shaped blade.
  • the fixture for supporting the part being treated which is generally designated by the reference numeral 1
  • a roller 2 for the advancement of the part being treated which is shown schematically and is designated by the reference numeral 3.
  • the roller 2 is arranged frontally with respect to a cup-shaped blade 4 having a circular cutting edge on its front rim and a rotation axis which is substantially perpendicular to the rotation axis of the advancement roller 2.
  • the advancement roller 2 is arranged below a shoe 5 which delimits in practice the region for the passage of the part being treated 3, thus adjusting the depth and type of the cut.
  • the fixture comprises a front movable guide 10 which can be arranged so as to adjust the cutting width; for this purpose, it can oscillate about an axis which is substantially parallel to the axis of the cutting blade.
  • the movable guide 10 which is laterally adjacent to the shoe 5 in the travel direction of the part being treated, is connected to a supporting surface 10a which is in turn supported by a first arm 11 connected to a first shaft 12 which is in turn connected, at its other end, to a first linkage 13 whereon a first piston 14 acts; through its translatory motion, the piston 14 rotates and positions the front movable guide 10.
  • the characteristic of the invention is constituted by the fact that there is provided a lateral movable guide, designated by the reference numeral 20, which is arranged in practice laterally to the shoe 5 in the direction which is substantially perpendicular to the travel direction of the part 3 and ends flush with the cup-shaped blade 4, thus providing support for the hide in the region that must not be affected by the cutting action of the blade.
  • the lateral movable guide 20 can lie above the supporting surface 10a, supports the hide and in practice prevents the hide from being cut in the region affected by the lateral movable guide.
  • the lateral movable guide can also oscillate about an axis coinciding with the oscillation axis of the front movable guide.
  • the movable guide 20 is supported by a second arm 21 which is connected to a second shaft 22 which is coaxial to the shaft 12 and is rigidly coupled to a second linkage 23 which protrudes radially from the shaft 22 and is connected to a second piston 24 so as to adjust, by means of the translatory motion of the piston, the angular position of the lateral movable guide.
  • the positioning of the lateral movable guide allows to always be certain of the width of the beveling.
