Description

Известен способ получени  пружин, при котором сначала навивают заготовку кратной длины без удлиненного витка, а затем разрезают на отдельные пружипы требуемой длины . Описываемый способ навивки спиралей позвол ет снизить трудоемкость изготовлени  спиралей с пр мыми концами, дл  чего заготовку навивают с периодически повтор ющимс  удлиненным витком, подвергают термообработке и затем разрезают удлиненные витки, получа  спирали с пр мыми концами. На чертеже приведена схема навивки спиралей . Спираль навивают на оправку /, вращаемую шпинделем 2. Из шпиндел  периодически выдвигаетс  палец 3, образующий удлиненный виток спирали 4. После термообработки спиралей удлиненные витки разрезают, получа  спирали с пр мыми концами. Предмет изобретени  Способ навивки спиралей, при котором сна чала на оправку навивают заготовку кратной длины, затем разрезают ее на мерные отрезки , отличающийс  тем, что, с целью снижени  трудоемкости изготовлени  спиралей с пр мыми концами, заготовку навивают с периодически повтор ющимс  удлиненным витком, подвергают термообработке и затем разрезают удлиненные витки, получа  спирали с пр мыми концами.There is a known method for producing springs, in which the first one is wound a workpiece of a multiple length without an elongated coil, and then cut into individual springs of the required length. The described method of winding spirals reduces the laboriousness of manufacturing spirals with straight ends, for which the workpiece is wound with a periodically repeated elongated turn, subjected to heat treatment, and then cut the elongated turns to get spirals with straight ends. The drawing shows the scheme of winding spirals. A spiral is wound on a mandrel / rotated by a spindle 2. A finger 3 is periodically extended from the spindle, forming an elongated turn of the spiral 4. After the heat treatment of the spirals, the elongated turns cut to obtain spirals with straight ends. The subject of the invention. A method of winding spirals, in which the mandrel is wound a multiple-length billet, then cut it into measured lengths, characterized in that, in order to reduce the labor intensity of manufacturing spirals with straight ends, the billet is wound with a periodically repeated elongated turn, heat treatment and then cut the elongated coils to obtain spirals with straight ends.
