Description

Известны способы изготовлени  S-образных заводных пружин, например прот гиванием вокруг оправки деформируемой ленты. Однако эти способы трудоемки, не придают деформированной ленте устойчивой формы и не обеспечивают нужной упругости.Methods are known for manufacturing S-shaped winding springs, for example, by drawing a deformable tape around the mandrel. However, these methods are laborious, do not give the deformed tape a stable form and do not provide the necessary elasticity.

Описываемый способ устран ет указанные недостатки, заключаетс  в том, что лента после деформации подвергаетс  термофиксации длительным нагревом в свободном состо нии.The described method eliminates these drawbacks, namely, that the tape, after deformation, is subjected to heat-setting by prolonged heating in a free state.

На чертеже изображена схема выполнени  способа.The drawing shows a diagram of the method.

Процесс изготовлени  пружин происходит следующим образом. Заготовка в виде металлической ленты / подвергаетс  трем операци м. При первой операции производитс  формование внутренних витков путем огибани  одного конца ленты вокруг оправки 2 на 1-2 оборота. При второй операции заготовка деформируетс  однократным прот гиванием вокруг оправки 3 другого конца ленты, прижимаемого к последней подпружиненным упором 4- В результате этой операции лента свертываетс  в кольцо по спирали, которое затем подвер1ают длительному нагреву в печи с целью фиксации. Это последн   треть  операци .The process of manufacturing springs is as follows. The blank in the form of a metal tape / is subjected to three operations. In the first operation, the inner turns are formed by bending one end of the tape around the mandrel 2 by 1-2 turns. In the second operation, the workpiece is deformed by single-handed drawing around the mandrel 3 of the other end of the tape, pressed against the latter by a spring-loaded abutment 4. As a result of this operation, the tape is coiled into a ring, which is then subjected to prolonged heating in an oven for fixation. This is the last third of the operation.

Смещение волокон металла, достигнутое деформацией на оправке 3, закрепл етс  термофиксацией, благодар  чему при изменении формы пружина стремитс  прин ть исходное состо ние.The displacement of the metal fibers, achieved by the deformation on the mandrel 3, is fixed by heat setting, so that when the shape changes, the spring tends to assume the initial state.

Такой способ изготовлени  упруги.х деформированных пружин обеспечивает устойчивость приданной им формы.This method of manufacturing resilient springs ensures the stability of their shape.

Предмет изобретени Subject invention

Способ изготовлени  S-образных заводных пружин путем прот гивани  вокруг оправки деформируемой ленты, один-два витка которой закреплены на подвижной оправке, отличающийс  тем, что, с целью придани  деформированной ленте устойчивой формы, т. е. повышени  ееA method of manufacturing S-shaped winding springs by pulling a deformable belt around the mandrel, one or two turns of which are fixed on a movable mandrel, characterized in that, in order to give the deformed belt a stable shape, i.e.

качества, ленту после деформации подвергают термофиксации путем дл1 тельного нагрева в свободном состо нии.after deformation, the tape is subjected to heat-setting by heating in a free state.
