Tools for building production and woodworking made from the perforated steel wastes
ArticleThe rising of efficiency of the building and construction production is an actual task. One of the possible ways to ensure higher efficiency is using innovative tools and facilities of small-scale mechanization, which increase productivity and enchase working condition. Most observable influence of such strategy is on concrete works, plastering and earthworks. Another important tendency in production engineering, building and construction production is recycling of the technological wastes, which sufficiently reduce cost of the products and improve ecology. The goal of the present paper is to offer new possibility for recycling of the technological wastes, i.e. perforated steel tapes achieved after stamping of fine parts, by producing from mentioned perforated tapes the building tools and facilities of small-scale mechanization. In particular, the technological wastes of the JSC ‘Ditton’ (Daugavpils, Latvia) – perforated steel tapes – received after stamping of the elements of driving chains for different apparatus were used in this research. The prototypes of the scrapers for the finishing building work, as well as cutting edges and circular coronas for the woodworking were elaborated and offered in this work. The results of approbation of elaborated prototypes of the tools are offered. It was proven, that proposed innovative tools could be used effectively in building production and woodworking
Band structures for binding and holding of objects made from recycled metallic materials
ArticleThe aim of the present research is the investigation of the possibility and effectiveness
of using the band structures made from recycled metallic materials for binding and holding of
objects (in particular, tubular objects as pipelines or shells). The using of band elements and
structures as such is a perspective way to increase the safety and bearing capacity of the pipelines
and vessels. Nowadays during repair works the outer surfaces of the mentioned objects are
braided by the steel tapes, i.e. the objects are strengthened by the binding. The mentioned steel
bands are specially produced for binding purpose. From the other hand after stamping of smallsize
details (like the elements of supply chains for different apparatus) the metallic waste in the
shape of perforated metallic tapes are received and needs to be reused in compliance with the
good practice in effective resource using and recycling. The band structures for binding and
holding of tubular objects, produced from the perforated metallic tape by the longitudinal
profiling, multilayer and spiral winding are presented. It is proposed to apply in industry the
composite band structures made from perforated metallic materials and epoxy matrix for binding
and holding of tubular objects as pipelines or shells, which allows simplifying and speeding up
the repair works especially in the cases of the local damages
Manufacturing of cellular structures from perforated metallic materials
Abstract: This research regards the manufacturing of cellular structures with through channels of different form from perforated steel tape. These methods allow recycling of metal wastes (tapes), which are obtained during stamping of fine-sized details. There are given examples of steel wastes with different physical-mechanical properties and geometry. The methods of profiling and welding of thin perforated materials are studied. A method of through channel parameter evaluation is suggested. The estimation of parameters of cellular structures during deformation is suggested
