Description

一种叠加对顶波簧 技术领域
本申请涉及波形弹簧技术领域，具体涉及一种叠加对顶波簧。
背景技术
对顶波簧是由长条形片状的金属丝沿轴向螺旋绕制加工形成，每一圈具有若干波峰和波谷，对顶波簧相对于普通螺旋压簧，具有可在承受相同负荷时、只占据一半或更少轴向空间的优点，其广泛应用于机械制造业、液压设备等行业。
传统的对顶波簧如图7所示，波形为倾斜向下弯曲形成，第一半波01的右端低点延伸至下一层波圈第二半波02的波峰处，这样收口时的波形高度不一，也即垂直度不好，而垂直度对波簧的性能影响较大。
而另外一种叠加层数波簧如图8所示，其金属丝沿轴向螺旋弯曲形成，每一层均呈波浪状，各层波形为上下重叠贴合设置，也即每一层的波峰与波峰对应贴合设置，波谷与波谷对应贴合设置，叠合波形弹簧虽然垂直度较好，但是其可用行程短，弹性性能较差。因此，急需设计一种垂直度好、且在保证较大刚度下具有较好弹性性能与较高可用行程的对顶波簧。
发明内容
因此，本申请要解决的技术问题在于克服现有技术中的对顶波簧不能同时保垂直度好和弹性性能好的缺陷，从而提供一种垂直度好、可用行程高且在保证较大刚度下具有较好弹性性能的叠加对顶波簧。
为此，本申请提供一种叠加对顶波簧，包括若干个叠加层数波簧和连接簧，每一所述叠加层数波簧沿轴向螺旋弯曲形成，且每一层均呈波浪状，各层波形为重叠贴合设置；连接簧，至少有一条，其连接相邻两个、呈上下叠放设置的 叠加层数波簧，以使相邻两个所述叠加层数波簧的第一波谷与第二波峰对顶相抵，第一波峰与第二波谷呈上下相对设置。
所述连接簧设于相邻两个所述叠加层数波簧的上下相对的所述第一波峰和所述第二波谷之间，其一端与在上设置的所述叠加层数波簧底层的所述第一波谷相连，另一端与在下设置的所述叠加层数波簧顶层的所述第二波峰相连。
多个所述叠加层数波簧和所述连接簧由同一条片状金属丝一体绕制形成。
所述连接簧包括与在上设置的所述叠加层数波簧的底层贴合连接的第一段，与在下设置的所述叠加层数波簧的顶层贴合连接的第二段，以及连接所述第一段和所述第二段的斜线段。
所述斜线段与所述第一段和所述第二段的连接处均为圆弧过渡连接。
所述第一段和所述第二段的长度均为1个波形长度的1/6-1/4。
所述连接簧为平线形。
所述连接簧为与在上设置或在下设置的所述叠加层数波簧紧密贴合的半波形。
所述波浪状为正弦形。
所述叠加层数波簧的每一层至少包括两个正弦波。

2.本申请提供的叠加对顶波簧，连接簧设于相邻两个叠加层数波簧的上下相对的第一波峰和第二波谷之间，其一端与在上设置的叠加层数波簧底层的第一波谷相连，另一端与在下设置的叠加层数波簧顶层的第二波峰相连，上述连 接簧的结构使得多个叠加层数波簧和连接簧由同一条片状金属丝一体绕制形成，这样加工快捷方便，大大提高了生产效率，降低了生产成本。
3.本申请提供的叠加对顶波簧，连接簧包括与在上设置的叠加层数波簧的底层贴合连接的第一段，与在下设置的叠加层数波簧的顶层贴合连接的第二段，以及连接第一段和第二段的斜线段，这样连接簧呈波浪形设置，从而增大了弹性性能。
