Hoe wordt de oorloze borgring gemaakt?

How is the earless snap ring made? Now let’s have a look! Snap ring without ear the manufacturing process mainly includes winding, hook making or two end face processing, heat treatment and process performance test, as well as necessary strong pressure or shot peening and other strengthening treatments.

There are two methods of winding: cold winding and hot winding. The snap spring steel wire with a diameter of less than 8-10mm is used to make the spring with cold coil. The cold spiraalveer is mostly made of cold drawn excellent * carbon spring steel wire that has been overheated in advance. After being rolled, it is only tempered at low temperature to eliminate internal stress. The hot coil is used when the spring steel wire with larger diameter is manufactured. According to the different diameter of the spring wire, the hot coil temperature is selected in the range of 800-1000 ¡æ. Quenching and tempering treatment should be carried out after rolling.

Voor belangrijke drukveren, om ervoor te zorgen dat het draagoppervlak aan beide uiteinden loodrecht op zijn as staat, moet de eindring plat worden geslepen op een speciale slijpmachine om de mogelijkheid van doorbuiging bij belasting te verminderen; Voor trek- en torsieborgringen moeten aan beide uiteinden haken worden gemaakt om het aansluiten en laden te vergemakkelijken. Om het draagvermogen van de veer te verbeteren, kan een sterke druk, een sterke spanningsbehandeling of een kogelstraalbehandeling worden uitgevoerd. De sterke drukbehandeling van de drukveer is om de veer samen te drukken contact elke spoel met een belasting die de elasticiteitsgrens van de veer overschrijdt materiaal after the spring is rolled, and keep it for 6-48h, so as to produce plastic deformation in the spring wire, and generate residual stress in the spring after unloading. Because the direction of residual stress is opposite to the working stress, the  large stress of the spring in operation is smaller than that of the spring without strong pressure treatment, so the bearing capacity of the spring can be improved. The tension snap ring is subject to strong tension treatment. After the spring is subjected to strong pressure and strong tension treatment, it is not allowed to carry out any heat treatment, and it is not suitable to work at a high temperature of 150-450 ¡æ and long-term vibration, otherwise it will lose the above effect.
