Description
技术领域technical field
本发明涉及一种高性能弹簧的成形技术，特别是一种高性能弹射形弹簧弹性卷筒的成形技术。The invention relates to a forming technology of a high-performance spring, in particular to a forming technology of an elastic reel of a high-performance ejection spring.
背景技术Background technique
弹簧是利用材料的弹性作用制成的储能零件，功能上可用于减震,夹紧,储能和测量等。现有弹簧分类主要有压缩弹簧、拉伸弹簧、扭转弹簧、平面涡卷弹簧、固力特弹簧。广泛用于机械、电子、石油化工、航空航天等各领域。The spring is an energy storage part made of the elastic effect of the material, which can be used for shock absorption, clamping, energy storage and measurement in function. The existing spring classifications mainly include compression springs, tension springs, torsion springs, flat scroll springs, and solid springs. Widely used in machinery, electronics, petrochemical, aerospace and other fields.
现有传统弹簧在行程较大场合下有较大限制，行程较长情况下易失去其刚性，弹出精确度较差。弹性卷筒正适用于这种环境。克服了现有弹簧在行程上的局限性，解决某些特殊场合下需将载荷自驱动弹出至指定位置的情况，其外形成螺旋筒状，展开长度较长，展开可达6米以上，收拢后仅为带宽高度，各卷层自由状态下为等直径，层间具有较强的抱紧力，展开后性能相当于薄壁管。但其形状复杂，长度长，最小直径小等特点，在成形方法上存在较多难点。Existing traditional springs have relatively large limitations when the stroke is large, and tend to lose their rigidity when the stroke is long, resulting in poor pop-up accuracy. Elastic rolls are just right for this environment. It overcomes the limitations of the existing spring in terms of travel, and solves the situation that the load needs to be self-driven to eject to the designated position in some special occasions. The last is only the width of the belt, and each roll layer is equal in diameter in a free state, and the layers have a strong holding force, and the performance after unfolding is equivalent to a thin-walled tube. However, due to its complex shape, long length, and small minimum diameter, there are many difficulties in the forming method.
发明内容Contents of the invention
本发明要解决的关键技术问题是，解决传统弹簧的行程局限性问题，克服弹性卷筒成形工艺上的难点。采用从以一定角度布置的成形模具中拉出成形的方式对弹性卷筒进行成形。The key technical problem to be solved by the invention is to solve the problem of the travel limitation of the traditional spring and overcome the difficulty in the forming process of the elastic roll.

The concave mold has no rounded corners or rounded corners to ensure that the two mold blocks fit together without gaps. The helix angle of the elastic reel product is guaranteed by the angle between the mold and the vertical direction of the strip, and the angle ranges from 1 to 85 degrees. The forming diameter of the elastic reel is guaranteed by adjusting the gap between the punch and die, and the gap is: the thickness of the thin strip is ~20mm.
