Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for performing the method according to the preamble of claim 5.
  • burrs on the pipe ends are inevitable.
  • many pipes especially hydraulic pipes in aircraft construction
  • the pipe end faces be burr-free, i.e. sharp-edged and at right angles to the pipe longitudinal axis.
  • the reason for this requirement is that when such pipes are bluntly flanged, no unevenness may occur at the transitions which cause greater turbulence in the hydraulic fluid. Burrs left standing also harbor the risk that they will be separated during operation and ultimately lead to malfunctions in the hydraulic system.
  • the object of the present invention is to provide a deburring method with which in particular the saw burrs on the end faces of thin metal tubes can be removed in a simple manner.
  • burrs on the inside of the pipe are removed by grinding the pipe end face from the inside out, so that a shaft-edged, burr-free cut is always achieved.
  • a secondary grinding burr thus formed is completely shifted to the outside and is subsequently machined, for example by means of an elastically bonded, deformable grinding tool attached to the outside, the outer edge of the pipe being used is slightly rounded.
  • the result is an exactly right-angled pipe with a sharp-edged, burr-free inner edge and a slightly rounded, burr-free outer edge.
  • a particular advantage of the invention is that burrs on the tube faces are reliably eliminated even with thin-walled and very long steel, stainless steel or titanium tubes of small diameter and thus low inherent rigidity.
  • the machining accuracy is high and damage to the pipe by hooking the machining tool into a strongly adhering burr is not possible.
  • the method according to the invention can be carried out inexpensively and fully automatically.
  • Fig. 1 shows a greatly enlarged longitudinal section of a pipe 1, on the front side of which both ridges 1a are located on the inside and outside of the pipe, which burrs have arisen due to a saw cut or by cutting the pipe to length due to another separation process. 1 shows the pipe 1 to the right after the burrs have been removed by the method according to the invention.
  • the tube 1 to be deburred is rotatably mounted on a carrying device 2.
  • the carrying device 2 can for example consist of two there are parallel rows of interlocking rollers which form a conveyor trough between them.
  • the tube 1 is set in rotation by a pressure device, which consists, for example, of a friction wheel 3.
  • a pressure device which consists, for example, of a friction wheel 3.
  • the grinding belt 5 is adjusted by means of a contact disc 6 of small diameter with exact adjustability of the contact line so that the grinding process takes place in the area of a zone 7 between the pipe central axis 8 and the pipe wall, the running direction 5a of the grinding belt 5 being chosen so that the grinding direction from the inside of the pipe to the outside of the pipe.
  • the end face of the pipe and the grinding belt 5 oscillate in the transverse direction relative to one another, with short pipes the device can oscillate, with longer pipes the grinding belt oscillates.
  • the grinding belt simultaneously grinds the pipe precisely at right angles and also removes a strongly adhering saw burr.
  • the crucial point with the present method is that the poorly accessible ridge on the inner edge of the tube face without residues, i.e. is removed without the formation of secondary burrs, and a secondary grinding burr is only formed on the outer edge of the pipe end face. This can be removed using known means, for example an elastic grinding wheel or a brush.
  • FIG. 3 shows the pipe to be processed 1, the is rotatably mounted on two rows of support rollers 2.
  • the friction wheel 3 is arranged above the tube 1 and is rotated by a drive 9.
  • the speed of the friction wheel 3 can optionally be adjustable.
  • the friction wheel 3 is brought into contact with the tube 1 by means of a lifting cylinder 10 (FIG. 3 shows the raised position of the friction wheel 3).
  • the friction wheel advantageously consists of an elastic material, for example rubber or plastic.
  • the axis of rotation 4 of the friction wheel 3 can be adjusted with respect to the central axis 8 of the tube 1 by means of an adjusting cylinder 11.
  • the tube 1 is either conveyed against the grinding belt 5 of a grinding device 16, or is withdrawn.
  • the grinding belt 5, which is arranged on the end face of the tube 1, runs e.g. Via the contact disk 6 and two deflection disks 12 and 13, one of which is driven and the second tensions and centers the belt.
  • the grinding belt 5 with the disks 6, 12 and 13 is arranged vertically, but it is also one other arrangement possible. It is crucial that the grinding belt 5, guided through the contact disk 6, comes into contact with the end face of the tube 1 below the central axis 8 in accordance with the method described above.
  • a lifting device 14 is provided in FIG. 3 for setting the contact zone 7 (see FIG. 2).
  • a drive device 18 is provided under the support rollers 2, with which the tube 1 oscillates in the transverse direction to the grinding belt 5 is moved. With very long pipes, it may be more practical to instead set the grinder 16 in a transverse motion.
  • the pressure time by the friction wheel 3 is controlled by means of a timer.
  • the required processing time and the amount of pressure depend on the pipe diameter and the wall thickness as well as on the pipe material.
  • a similar grinding device 16 and a further grinding tool 19 can be arranged on the other side of the carrying device with the carrying rollers 2. so that the machining first takes place at one end of the pipe and then at the other.
  • a pipe grinding system according to the invention can have two substantially parallel pipe carrying devices, on the opposite ends of which a grinding device 16 and a grinding tool 19 are arranged. Deburring on the right and deburring on the left are thus carried out in different conveyor troughs, the entire system being linked in such a way that machining to the right and left takes place almost simultaneously.
  • the deburring stations are stationary and the workpieces are transported from right to left or vice versa before, during and after the transfer from channel to channel.
  • Centerless external cylindrical grinding with suitable tools following internal deburring can completely replace the tool described in the text under 19 and at the same time improve the pipe surface.
