Definitions

  • the present invention relates to a body having a surface or surfaces subjected to friction when the body is put to practical use at a workplace or site of use, which surfaces are coated with a lubricant already on production in the factory and delivered coated with lubricant.
  • the lubricant has so far been, applied with some suitable lubricating tool, e g it has been injected into the hole wherein the detail or body in question is to be inserted, which signifies an extra work operation and a messy job in many cases as well.
  • the object of the present invention is to provide bodies or details with a prefabricated, lubricant-coated surface, the above-mentioned work operations at the site of use being eliminated, a messy lubricant surface substantially being avoided and the intended achievement of lubricating effect guaranteed.
  • the invention is characterized in that the lubricant-coated surface outside the lubricant is provided with a protective coating of such a material which has a certain lubricating effect and which breaks already at the beginning of the insertion in the material or hole, so that the underlying lubricant comes out.
  • the protective layer preferably comprises paraffin or stearin, said materials being lubricanting per se, and easily break already at moderate loading.
  • a protective layer can also be simply produced by dipping in a melt having a correctly adjusted temperature.
  • the body constitutes a conical driving tip for perforating a fire-sealing lead-through comprising an elastomeric fire-resistant foamed material.
  • Figure 1 illustrates making a hole through a fire-sealing body.
  • Figure 2 is a section to a larger scale along the line II-II in Figure 1.
  • FIG 1 illustrates a fire-sealing body 1 inserted, e g moulded-in, in a wall 2.
  • the fire-sealing body comprises a foamed material 3, suitably a silicon foam, which expands inside a surrounding casing 4 and assumes a foamrubber-like consistency in the production of the fire seal.
  • the foamed material is kept compressed by the casing transverse the longitudinal axis of the casing.
  • a perforating tool which here comprises three parts, namely a conical tip 5, sleeve 6 and a handle 7 with a head S.
  • the tip 5 is at first suitably pressed by itself into the foamed material 3.
  • the forward end 9 of the sleeve is inserted in the tip, and with the aid of the handle the tip and sleeve are pressed through the foamed material, and when the tip has passed through the material it falls off by itself.
  • the handle 7 may press against the back end 10 of the sleeve, there being an annular bottoming groove made in the head 8 of the handle for insertion of the sleeve end during the through penetration.
  • the head 8 By special forming of the head 8 with a recess 11 for hooking onto two of four abutments 12, uniformly distributed round the circumference of the sleeve 6, and situated in the vicinity of the back end of the sleeve, through pen etration of the tip 5 and sleeve 6 can take place, after such a hooking- on, alternatively with a position for the handle 7 which is oblique relative the sleeve, and this can be valuable in more inaccessable places.
  • the sleeve 6 After the sleeve 6 has been urged through the fire-sealing body 3 and a conduit has been passed through the sleeve, the sleeve is withdrawn with the aid of the handle 7.
  • the tip 5 is provided with a coating of lubricant 13 and outside this coating a protective layer 14. It is essential that the protective layer 14 has a lubricating effect without being messy to handle, and that it breaks up at the mechanical loading to which the tip 5 is subjected at the beginning of penetration, so that the lubricant comes out and spreads round the tip.
  • a suitable material for the protective layer has been found to be paraffin or stearin. Apart from the above-mentioned properties, there is obtained with such material the advantage of simple production by dipping the tips 5 in a melt at a correctly adjusted temperature. With a lubricant coating 13 and a protective layer 14, as described above, it has been found that the penetration and withdrawal force was reduced to 1/2 - 1/3 of the force required without these layers.

Abstract

Pendant sa production a l'usine, un corps est enduit de lubrifiant (13) sur sa surface ou surfaces qui sont exposees au frottement lors de l'utilisation du corps a son endroit d'utilisation. A l'exterieur du lubrifiant on applique une couche de protection (14) composee d'un materiau sensiblement non salissant, de preference de la paraffine ou de la stearine, ce materiau ayant un certain effet lubrifiant et se fissurant au commencement de l'utilisation du corps de maniere telle que le lubrifiant sous-jacent soit distribue uniformement sur la surface du corps.
