Description

Фиг. 1FIG. one

Изобретение относитс  к технологии машиностроени  и может быть использовано при изготовлении пружин сжати  с проволокой пр моугольного сечени .The invention relates to mechanical engineering technology and can be used in the manufacture of compression springs with rectangular wire.

Целью изобретени   вл етс  повышение надежности и ресурса работы пружинЕ..The aim of the invention is to increase the reliability and service life of the spring.

На фиг. 1 показана заготовка пружины; на фиг. 2 - то же, с поджатыми нерабочими витками; на фиг. 3 - готова  пружина.FIG. 1 shows a spring blank; in fig. 2 - the same, with preloaded non-working coils; in fig. 3 - spring is ready.

Способ изготовлени  пружин сжати  заключаетс  в следующем.A method for manufacturing compression springs is as follows.

На трубчатой заготовке нарузают канавку с шагом, равным шагу пружины, и глубиной , равной половине разницы между внешним и внутренним диаметром пружины. Затем производ т формообразование опорных витков путем расточки внутреннего отверсти  трубчатой заготовки на участке опорOn the tubular billet, a groove is broken with a step equal to the spring pitch and a depth equal to half the difference between the outer and inner diameter of the spring. Then, the support coils are formed by boring the inner hole of the tubular billet at the site of the supports.

ных витков до диаметра, равного внутреннему диаметру винтовой канавки, и поджимают опорные витки. После формообразовани  опорных витков заготовки пружины внутреннее отверстие растачивают на участке рабочих витков до диаметра, равного внутреннему диаметру винтовой канавки.coils to a diameter equal to the inner diameter of the helical grooves, and tighten the reference coils. After shaping the support coils of the spring blank, the inner hole is bored on the section of the working turns to a diameter equal to the inner diameter of the helical groove.

Пример. На трубчатой заготовке с внешним диаметром и внутренним диаметром ёдр нарезают винтовую канавку с шагом t, равным шагу пружины, и внутренним диаметром dj (фиг. 1). Затем растачивают внутреннее отверстие трубчатой заготовки на участке опорных витков до диаметра d и поджимают опорные витки (фиг. 2). После формообразовани  опорных витков внутреннее отверстие заготовки пружины растачивают до диаметра dвн.пp-(фиг. 3).Example. On a tubular billet with an external diameter and an internal diameter of a jerk, a screw groove is cut with a step t equal to the spring pitch and the internal diameter dj (Fig. 1). Then bore the inner hole of the tubular billet in the area of the support coils to diameter d and tighten the support coils (Fig. 2). After the shaping of the support coils, the internal opening of the spring blank is bored to a diameter dvn.pp- (Fig. 3).
