Definitions

  • the invention relates to a deburring machine for ends of cut-to-length sections of a long profile and to a method for deburring ends of cut-to-length sections of a long profile.
  • Deburring machines in particular brush deburring machines, are already known in the art DE 10 2010 046 392 A1 known.
  • Brush deburring machines are generally not used on their own, but in combination with pipe cutting machines that cut lengths of pipe from a metal pipe at high speeds. The cut sections are then treated further. The further treatment can take place in various sequential process steps, in particular pipe ends can be chamfered and / or washed and / or deburred.
  • the brush deburring machine frees the ends and cut surfaces of the metal tubes during their transport by means of transport discs from sharp burrs left over in the cutting process.
  • a brush deburring machine which transports pipe sections by means of drivers along oppositely rotating brush rollers. The pipe sections are fed individually to the Bust deburring machine.
  • the object is met in a first aspect by an aforementioned deburring machine with the feature of claim 1 and in a second aspect by a method having the features of claim 7.
  • Preferred embodiments of the deburring machine are the subject of the respective subclaims.
  • the deburring machine is characterized on the one hand by a receptacle for a stack or a bundle of cut sections of a long profile and by a separating device for the sections and a transport device for the individual sections and at least one arranged along the transport brush, which preferably rotates and during the transport of the separated sections is in contact with the ends of the individual sections and deburred by the rotation of the cut surfaces of the cut sections.
  • the deburring machine according to the invention makes it possible in a simple manner to maintain a multiple cut which is important for the speed of the sawing process, by cutting through stacks or bundles of long profiles and by further processing the stack or bundles of sections forming thereby. Nevertheless, each individual section is subjected to individual treatment by the brushes by the singulator, and therefore the deburring process is performed as carefully as if the sections had been individually cut to length from the long profile and individually fed to further processing, in particular deburring.
  • the transport device has two rows of transport disks arranged side by side in the transport direction, which have pairs of recesses opposite to the transport direction for receiving the individual sections.
  • Each row of transport discs comprises staggered, partially overlapping even and odd transport discs.
  • 'even' and 'odd' refers to the consecutive in the transport direction numbering of the transport discs.
  • the straight transport discs are coupled together and the odd transport discs are coupled together.
  • the receptacle in which the stack or the bundle of sections is first inserted, is dimensioned to receive a plurality of sections.
  • the recesses of the transporting disks are each dimensioned only to receive a single section.
  • the pairwise opposite recesses allow the Recording a single cut-to-length section.
  • the cut sections are vortransportierbar by rotation of the transport discs in the transport direction. The rotation is preferably clocked and during each clock in the same direction.
  • the stack or bundle can be inserted directly into the receptacle at portions under immediate contact with the recess. If the recess is not positioned to be part of the receptacle, the stack or bundle will make direct contact with the transport disc. However, if the transport disk is rotated so far that one of the recesses is part of the receptacle, preferably arranged directly adjacent to the stop, the entire stack or the entire bundle can be inserted into the receptacle such that preferably exactly one section is positioned in the associated recess is and makes contact with the wall of the recess.
  • the receptacle comprises alternating Einzelaussparungspaare and at least one arranged in the direction of rotation of the first transport disc before recording stop and a arranged in the rotation direction behind the stack receiving holder.
  • the receptacle is therefore made variable during the entire deburring process of a stack or bundle of sections, although it has a constant stop and a constant holder, but changing Aussparungspaare.
  • a transfer device of the stack or the bundle is provided at portions of a cutting device directly into the receptacle of the deburring machine.
  • the transfer device is preferably designed as a gripper, which engages the simultaneously cut sections as a stack or bundle and inserts as a stack or bundle in the receptacle, where they have direct contact with the associated recess or the pair of recesses.
  • odd recesses of an odd transport disc have a greater length along the circumference than a depth in the radial direction
  • recesses of a straight transport disc have a smaller length along the circumference than a depth in the radial direction.
  • angular distances of adjacent recesses of straight and odd transport disks are formed differently from one another.
  • the invention is achieved by a method of deburring ends of a cut-to-length section of a long profile, preferably by means of one of the above-described deburring machines, by placing a stack or bundles of cut-to-length sections into a receptacle which isolates portions of the stack or bundle and then transporting the separated portions along a transporting direction and brushing the ends, preferably the cut surfaces, during transport.
  • the essential feature of the invention is that, despite the introduction of a stack or bundle of cut-to-length sections into a deburring machine, the actual brushing process takes place individually for each section and the entire stack is not brushed in the form of a stack.
  • the first transport disk pair is rotated continuously in a constant direction of rotation, and at each cycle, a lowermost, radially innermost portion of the section stack or bundle is taken in the transport direction and later transferred to the second transport disk pair.
  • the stack or bundle is inserted directly into the receptacle, the receptacle also having a recess here with the correct position of the first transport disc pair, so that the stack or bundle conveniently when inserting into the receptacle immediate contact with a wall of the recess of the first pair Transport discs accommodates, so that the inserted stack or the inserted bundle does not have to roll to the recess, but the sections of the stack or the bundle are separated directly and simultaneously transported by the transport disc.

  • Each odd notch 111 is intended to receive exactly one end portion of a flat oval profile section 3.
  • the Flachovalprofilabites 3 is located at its two end portions on a respective transport disk T 1 , T 2 of the transport disk pair and is conveyed by rotation of the transport disks T 1 to the next pair of transport disks T 2 and handed over in the overlap area.
  • the straight recesses 112 of the second and the straight transport disks T 2 are also adapted to the cross sections of the Flachovalprofile, however, the straight recesses 112 along the circumference of the straight transport disks T 2 are arranged and at 90 ° about an axis perpendicular to the transport direction T against the odd recesses 111th the odd transport discs T 1 rotated so that the straight recesses 112 along the circumference of the straight transport discs T 2 are narrow but formed along a radius R deep.
