Guardrail assembled by stamping and apparatus for assembly of same

Abstract

In present invention, there is disclosed a guardrail assembled by stamping including two rails, which are spaced from each other and disposed horizontally, and balusters, which are spaced from one another and disposed vertically. The rails are provided thereon with a plurality of spaced insertion holes. The insertion holes in the upper and lower adjacent rails are arranged in vertical alignment. The insertion holes in the rails are blind holes arranged to face inwards. The plurality of balusters are separately inserted into the vertically aligned insertion holes, allowing assembly and attachment of the plurality of balusters with and to the rails. Portions extending outwardly from walls of the insertion holes form abutment portions. After end portions of the balusters are inserted into the insertion holes, the end portions of the balusters are subjected to a stamping process so as to be bent outwardly to form rolled edge rims. The rolled edge rims abut against the abutment portion, achieving secure attachment of the balusters to the rails. The present invention provides the advantageous benefits of firm and secure assembly, convenient and fast assembly and good anti-corrosion performance.
