FASTENING METHOD Russian patent published in 2018 - IPC F16B5/02 

FIELD: technological processes.

SUBSTANCE: invention relates to a invention relates to a method for fastening a component to a base element and is directed to increasing the retention force of a fastening element in a blind hole at a predetermined depth. Method for fastening a component to a base element, in particular, consisting of a metal or an alloy, in which a blind bore is formed wherein the hole defines a depth direction and has a force transmission surface A, has a depth T in the depth direction, where T<10 mm, in particular T<8 mm, in particular T<6 mm, in particular T<4 mm, wherein the force transmission surface is in the frustoconical form with an opening half-angle β from 0 ° up to 20 ° and mean diameter d, wherein the blind hole has a conical blind bore base with an opening angle of the cone α from 60 ° up to 180 °, in particular from 88 ° up to 138 °, in particular from 98 ° up to 138 °, and at the edge has a bevel extending in the depth direction to bevel depth L of 0 to 2 mm, in particular from 0 to 0.5 mm, wherein mean diameter d of force transmission surface A is at least d=(1-√k)(T-L)tan(α/2) and at most d=(1+√k)(T-L)tan(α/2) with maximum surface tolerance k, where k=0.3, in particular k=0.2, in particular k=0.1, wherein the method comprises fixing the fastening element in a blind hole by means of a force transmission surface, and wherein said component is retained by a fastening element.

EFFECT: fastening method is proposed.
