Existem vários métodos de fabricação de anel de pressão sem orelha

How much do you know about the manufacturing method of earless snap ring? The manufacturing process of the earless snap ring mainly includes winding, the production of the hook or the processing of the two end faces, heat treatment and process performance test, as well as the 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 coil spring 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.

Para molas de compressão importantes, a fim de garantir que a superfície de apoio em ambas as extremidades seja perpendicular ao seu eixo, o anel da extremidade deve ser retificado em uma retificadora especial para reduzir a possibilidade de deflexão quando carregado; Para freios de tração e torção, devem ser feitos ganchos em ambas as extremidades para facilitar a conexão e o carregamento. A fim de melhorar a capacidade de carga da mola, pode ser realizada forte pressão, forte tratamento de tensão ou tratamento de shot peening. O tratamento de forte pressão da mola de compressão é comprimir a mola para contato each coil with a load exceeding the elastic limit of the spring material 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. The above is a summary of the manufacturing method of the earless snap ring.
