NEWEST PNEUMATIC ACTUATOR CONSTRUCTION FOR QUALITY IMPROVEMENT TECHNOLOGICAL ACTIONS IN PERFORMANCE OF FRICTION PULL THE CORD

Abstract

What properties of shoe are in-process considered there is qualificatory for the quality forming of details of top
facilities of the cord wearing out, among that most ponderable is : the technological loading on a flexible power element,
relative lengthening of material of top, coefficients of friction in the system shoe "diaphragm-material-tree", geometrical
parameters of surface of shoe tree, degree of distribution of normal pressures from the side of resilient diaphragms, speed of
displacement of the protracted edge and проч. a size and direction of appendix technological loading have Especially large
influence on cord, as exactly it determine size and distribution longitudinal and transversal deformation purveyance.
Equipment for implementation of technological operations of the cord tightening with the friction covering, created by the
improvement of pilot plant and application. Therefore this important factor must be taken into account yet on the stage of
planning of equipment for realization of tightening of this type. The question of the optimal execution of process states actual
friction cord затагивания and опытно-конструкторских developments on an equipment it is possible to perfect operating
technological processes on making of everyday shoe of mass production. Presence of the adopted structurally-technological
elements, and also results of theoretical and experimental researches confirm expediency of application of them in an
industrial bootmaking. It is educed, that the experimental setting that was used showed high exactness of results, mobility and
reliability, that is why there was the reasonable founding for the use of her structural elements as prototypes of capable
mechanisms of industrial equipment. The attempt of improvement of equipment is conducted with the purpose of prevention of
overload of equipment for the cord tightening, and also for the increase of term of his exploitation at technological effort on a
cord, that must not exceed 250Н. It is set that at implementation of technological operation of the friction cord tightening of
purveyances of top of shoe it is expedient to give pressure in пневмосистему in the interval of 1,5÷2,0мПа with the
simultaneous use of rubber for diaphragms with the not high module of resiliency. The worked out pilot plant for the cord
tightening with the friction covering gives an opportunity to prospect the operations of tightening and forming of details of top
of shoe with sufficient exactness. Thus the process of moving of elementary areas of material in accordance with the got
external loading and internal tensions comes true, id est there is формообразование of top of shoe. For the increase of
exactness of fitting closely and providing of even pressure of diaphragms, the increases of speed of tightening process must be
applied reliable and exact mechanism of moving of friction scopes. Оffer by us the newest chart of airisanoccasion intended
for a management by work by friction scopes and realizations by them friction covering of purveyance. Thus, analysing
technological and technical parameters, it is possible to assert that basic advantages of the airisanoccasion system is
simplicity, reliability, longevity and economy, that is conditioned by a одноканальным feed (exhaust air is produced directly
in an atmosphere without offtake pipelines) and cheapness of working environment (air). As a result of small sensitiveness of
air to the change of temperature of description of airisanoccasion. I am stable it is necessary to define that repressing
direction of perfection of construction of mechanisms of machines of light industry is combination of exactness of flexibility,
energyeconomy, mobility, capacities for automation at a speed of implementation of motive actions. Such effective renderingengine can be a pneumatic drive on the basis of small airisapum
