Description

Известные устройства дл  испытани  проволоки на усталость циклической переменной нагрузкой не дают возможности производить испытани  при несимметричном цикле, т. е. ири одно временном действии на проволоку знакопеременных изгиба и зиакопосто нных переменных напр же шй раст жени .The known devices for testing fatigue of a cyclic variable load do not allow testing with an asymmetrical cycle, i.e., simultaneously acting on the wire with alternating bending and bioaccumulative stress tensile variables.

Предлагаема  машина дает возможность проводить испытани  проволоки при одновременном раст жении и изгибе, что позвол ет опреле-л ть предел выносливости при несимметричном цикле.The proposed machine makes it possible to test the wire while stretching and bending at the same time, which makes it possible to determine the fatigue limit in an asymmetric cycle.

Схема предлагаемой машины изображена на чертеже.The scheme of the proposed machine is shown in the drawing.

Образец 1 проволоки закрепл етс  в зажимах 2. Вращением гайки 3 сжимаютс  пружины 4, создаюш,ие раст гивающее усилие в образце проволоки , которое определ етс  но шкале 5.Sample 1 of the wire is fixed in the clamps 2. The rotation of the nut 3 compresses the springs 4, creating a tensile force in the sample of the wire, which is determined on a scale of 5.

Изгиб образца производитс  при помощи опор 6 и 7, охватывающих среднюю часть образца и прикрепленных болтами 8 к пластине 9. Последн   укреплена на иттоке 10, который св зан шарниром //с шатуном 12, эксцентрнчно насаженным на вал 13 электродвигател .The sample is bent using supports 6 and 7, covering the middle part of the sample and bolted 8 to the plate 9. The latter is fixed on the yoke 10, which is connected by a hinge // with a connecting rod 12 eccentrically mounted on the shaft 13 of the electric motor.

При вращении вала электродвигател  шток 10 с пластиной 9 и с опорами 5 и 7 совершает возвратно-поступателвное движение. За один оборот вала 13 происходит полный цикл смены напр жений. Вал соединен со счетчиком, который отмечает число полных циклов изменени  напр жений в прОВолоке.During the rotation of the motor shaft, the rod 10 with the plate 9 and with the supports 5 and 7 makes a reciprocating movement. During one revolution of the shaft 13, a full cycle of voltage shift occurs. The shaft is connected to a meter, which indicates the number of complete stress cycles in a wiring belt.

Предмет и з о б р е т е и и  Subject and d on and e and

Машина дл  испытани  проволоки на усталость циклической переменной нагрузкой, отличающа с  тем, что, с целью проведени  испытаний при одновременном раст жении и изгибе испытуемой проволоки, зажимы дл  последней подпружинены , а между зажимами установлены охватывающие среднюю часть проволоки опоры, св занные с механизмом , сообщающим им возвратно-поступательное движение.A machine for testing fatigue of a wire with a cyclic variable load, characterized in that, in order to carry out tests with simultaneous stretching and bending of the test wire, the clamps for the latter are spring-loaded, and the supports covering the middle part of the wire are connected to the mechanism that informs them back and forth.
