Definitions

  • the invention relates to a method for surface treatment of an object, which is preferably placed on a conveyor belt with a view to being advanced and treated by wires on one or more rotating wire rollers, as well as a wire roller for performing the method, and use thereof.
  • abrasive or scraping tools have to be used in order to clean the surface by removal of both the coating as well as a portion of the object.
  • the free piece of wire which is to treat the object, is arranged such that it may be rotated during the treatment, as it will be rotated backwards when striking the object. This means that the object is subjected to a dissimilar impact stress depending on the backwards rotation of the wire that takes place and the elasticity of the wire itself.
  • the object of the invention is to improve the surface treatment, and this is achieved according to the invention by using a method wherein each wire roller rotates about a shaft extending radially from a revolving shaft which revolves, and wherein the revolving shaft and the wire rollers are moved transversely to the conveyor belt at the same time, so that the object is treated from all sides with a uniform impact stress from the wires on the wire rollers.
  • the method will bring about a completely uniform impact which will be able to remove coatings, both unevenly distributed coatings, such as soft shells, and fixed smooth coatings, such as oxide layers, layers of paint, burrs, etc.
  • the method will not affect the object in any way, since the object is left cleaned without any damage.
  • inox may be deburred without damaging the protective sheet.
  • galvanized objects may be deburred without removal of or damage to the zinc layer.
  • the treatment is completely uniform, which is of great importance, in particular where the method is applied for deburring, as the object is treated such that a completely uniform treatment is achieved by passage during the combined movement comprising rotation, revolving movement and transverse movement which the wire rollers perform.
  • the wire When, as stated in claim 3 , the wire is curved, so that, around the centre, it bows forwardly in the direction of rotation, an expedient impact angle will be achieved and thereby a maximum impact stress, and when the wire is twisted to form an eye, the wire may be mounted on a stay in the roller, and the individual wire turns will give an expedient damping of the wire because of the friction between the turns. After mounting, the rearmost part of the wire will bring about additional inertia, which will give an enhanced impact stress and also a good fixing of the position of the treating wire part because of the centrifugal force, which affects the wire as well as the wire extension which will be pressed against the adjacent stay.
  • the extension of the wire prevents the wire from being moved rearwards during the rotation, thereby intensifying the effect of the impact stress.
  • the method is applied for improving the adhesion, a uniformly treated surface having uniform adhesion properties is ensured.
  • FIG. 1 shows a system for performing the method, seen from above
  • FIG. 2 shows a longitudinal section through a wire roller, seen in the direction II-II in FIG. 3 ,
  • FIG. 3 shows a cross-section through the wire roller, seen in the direction III-IlI in FIG. 2 .
  • FIG. 4 shows a single wire and its movements in operation.
  • FIG. 1 shows the principle of the surface treatment of objects 7 , which may be metal or plastics objects, which are either to be surface-cleaned, deburred, surface-hardened or to be subjected in another manner to an impact stress provided by the wire.
  • objects 7 which may be metal or plastics objects, which are either to be surface-cleaned, deburred, surface-hardened or to be subjected in another manner to an impact stress provided by the wire.
  • the objects 7 are preferably arranged on a conveyor belt 11 , which may be a magnetic belt or a vacuum belt.
  • the objects 7 are moved inwards below the wire rollers 15 , of which six are provided in the example shown.
  • Each roller 15 is mounted on a shaft 6 which is caused to rotate and preferably such that adjacent wire rollers 15 are rotated in opposite directions, as indicated by arrows 8 .
  • the radially disposed rollers 15 are mounted in a revolving head which revolves around a vertical shaft 13 , as indicated by an arrow 12 .
  • the treatment of the objects 7 is thus a combination of three movements, viz. partly a revolving movement of the individual wire rollers 15 , partly a rotation 12 of the shafts 6 with the wire rollers 11 , and finally a reciprocal movement 14 of the equipment over the conveyor belt 11 .
  • the wire roller 15 is constructed on the basis of flanges 5 between which stays 4 , extending mutually in parallel, are mounted, said stays being equidistantly positioned around the flange 5 , as shown in FIG. 3 .
  • Wire elements are inserted on these stays 4 , said wire elements being uniformly bent and configured to form a wire I which treats the object, as will be described later.
  • FIG. 3 shows the actual configuration of the wire element, and it is noted that the wire is bent to form an eye 2 through which the stay 4 may extend, and such that the wire element may revolve around this stay.
  • the free end I of the wire is curved, as indicated in FIG. 3 , such that it points forwardly in its direction of rotation 8 .
  • the opposite end of the wire is configured as an end 3 which extends between the eye 2 and engages the adjacent stay 4 , as shown in FIG. 3 . It is ensured hereby that the wire element 1 , 2 , 3 assumes the correct position during the rotation of the roller about its centre axis 6 .
  • FIG. 4 shows the position of the wire before it strikes an object 7 .
  • the roller rotates in the direction of the arrow 8 at the same time as either the roller revolves 12 around the object and/or the object 7 is moved below the roller, e.g. on a vacuum belt 11 .
  • Spring wire is advantageously used, which is wear-resistant, and which has a suitable elasticity, but other materials, such as plastics wire and the like, may be used.
  • the wire diameter may e.g. be about 2 mm, the free end about 100 mm, and the rear end 3 about 60 mm. Other dimensions may be used, provided that the mutual ratios essentially correspond to this.
  • the wire may optionally be moved a small distance around the stay 4 , as indicated by the arrow 10 , just as it may bounce, as indicated by the arrow 9 .
  • the stop which is formed by the adjacent stay 4 , ensures that all the wires are secured in the same position, as indicated in FIGS. 3 and 4 , during the rotation.
