Definitions

  • the invention relates to a swing cutter blade unit for attachment to an electric or pneumatic vibratory cutter and a corresponding vibratory cutter. It further relates to a method for Ausglasen an insulating glazed window or door leaf.
  • the invention is therefore based on the object of providing an improved tool and improved method for Ausglasen of insulating glazed window or door wings, so that this work on the one hand is easy on the other hand, and damage to the frame can be largely avoided.
  • the invention is based on the consideration that when severing an elastic adhesive layer with a knife therefore complicate handling of the out of the frame to be taken insulating is to complain, because no material is dissolved out of the adhesive layer and therefore the cut edges are tightly and elastically pressed together , According to the inventor's considerations, it would therefore be desirable to achieve a material discharge from the adhesive layer even when using a knife or (as a further step) to make it easy. Furthermore, the invention includes the consideration that such a material discharge in the form of a resulting between two cutting blades separate adhesive strip can be realized, which can be relatively easily removed "in the piece" after the cut.
  • the distance between the two blades of the proposed blade unit in the range between 0.5 mm or 2 mm, in particular in the range between 1 mm and 1 , 5 mm. It will be appreciated that for other applications where wider adhesive layers are to be cut, a greater blade spacing may also be considered.
  • the blades are manufactured individually and are welded, brazed or riveted together near a receiving opening for attachment to a drive shaft of a drive unit.
  • one of the blades is doubled onto a prefabricated blade unit comprising a single blade.
  • the blade unit can also be manufactured from one piece or be assembled from individual parts in a manner other than that mentioned.
  • the blades have the same shape, in particular tapering towards its free end and are rounded there.
  • the blades can also have a different shape, in particular a hook-like curved shape, trapezoidal shape or the like.
  • Fig. 1 shows a compressed air-driven, hand-held vibratory cutter 1, at the device head 1a, a drive shaft 1 b protrudes from the housing. Attached thereto is a swing cutter blade unit 3 comprising two cutting blades 3a and 3b parallel to each other at a small distance from each other on a cranked blade holder 3c.
  • FIGS. 2A and 2B show, as exemplary embodiments, a blade unit 3 'with blades 3a', 3b 'tapering towards its free end with rectilinear boundary edges or a blade unit 3 "with hook-like blades 3a", 3b " Blades are identical, but in other designs the shape and / or the cut of the two blades may differ.
