Abstract
本实用新型涉及一种冷拉伸模具，属于模具。凹模与上模座固定连接，凸模通过连接螺钉将其固定于下模座上，压边圈通过螺钉与下模座固定连接，氮气弹簧通过连接螺钉固定于下模座上，氮气弹簧与压边圈下端固定连接，压边圈与凸模滑动连接。本实用新型的优点在于：结构新颖，材料利用率高，质量稳定，生产效率高，加工成本低，可加工薄壁、复杂零件，适宜批量生产。
Description
冷拉伸模具技术领域[0001 ] 本实用新型属于模具，尤其是指一种冷冲压模具。 背景技术[0002] 冷冲压的加工对象是主要是金属板材，在压力机的作用下，将材料加工成零件。我国冲压技术的现状是，技术落后，经济效益低。由于现有的成形工艺落后，标准化程度低，设计方法、手段及模具制造工艺设备落后，模具专业化水平低，导致模具寿命短、效率低、加工精度差、生产周期长。发明内容[0003] 本实用新型提供一种冷拉伸模具，以解决模具寿命短、效率低、加工精度差、生产周期长的问题。[0004] 本实用新型的技术方案是：凹模与上模座固定连接，凸模通过连接螺钉将其固定于下模座上，压边圈通过螺钉与下模座固定连接，氮气弹簧通过连接螺钉固定于下模座上， 氮气弹簧与压边圈下端固定连接，压边圈与凸模滑动连接。[0005] 本实用新型的优点在于：结构新颖，材料利用率高，质量稳定，生产效率高，加工成本低，可加工薄壁、复杂零件，适宜批量生产。附图说明[0006] 图1是本实用新型的结构示意图。 具体实施方式[0007] 凹模2与上模座1固定连接，凸模3通过连接螺钉将其固定于下模座6上，压边圈 4通过螺钉与下模座6固定连接，氮气弹簧5通过连接螺钉固定于下模座6上，氮气弹簧5 与压边圈4下端固定连接，压边圈4与凸模3滑动连接。[0008] 本实用新型的工作方式[0009] 氮气弹簧5的弹压力顶起，平稳状态下，把金属板料片7放入压边圈4上，凹模2 在外力压力机作用下向下移动与金属料片7接触，进一步下移，在氮气弹簧5的支撑工作压力与外力压力机的工作压力作用下，凹模2和压边圈4将金属料片7夹紧，凹模2继续下移与凸模3接触，再进一步下移逐步使金属料片7达到拉伸成型状态，完成产品的拉伸成型， 撤销凹模2的外力，压边圈4将在氮气弹簧5的作用下回到初始状态。
