模杯修边装置 技术领域
本发明涉及对三维弹性产品的加工领域， 特别涉及一种对乳罩等模杯进 行修边的装置。
背景技术
模杯泛指乳罩、 肩垫等三维弹性产品的弹性罩杯， 采用橡胶、 塑料等弹 性材质经模压机模压成型， 成型后轮廓线以外的边角需要修剪掉。 由于模杯 是三维结构， 模杯每一个边角可能都位于不同的面上， 因此现有技术中通常 采用人工用剪刀修剪， 但质量不稳定， 劳动强度大， 加工效率极低。 另一种 方法是采用普通平面冲裁， 但这种方法定位困难而且质量不可靠， 由于反复 冲裁会使砧板表面凸凹不平， 这样容易导致冲不断。 还有一种方法是采用平 车、 铡骨车装刀具修边， 但这种方法受经验影响较大， 会导致质量不稳定。 总之以上所述常见的三种方法的加工效率都非常低， 大约每分钟只能完成一 至两对产品的修边加工， 而且质量极不稳定， 不适用于规模性的加工。
此外在现有技术的相关文献中也介绍了有关模杯修边的设备， 例如： 申 请号为 200920196044. 0的中国专利申请文献中公开了一种模杯修边机构，它 是在平车缝纫机的基础上进行改造， 将针杆上的缝纫针换成切割用的刀片， 并在缝纫机面板上设有开口使得刀片与之配合完成切割动作， 这种结构由于 需要刀片沿着预定的轮廓线轨迹切割一周才能完成加工， 效率也不够理想； 而且被切割的模杯半成品难以稳定的定位， 切割过程出现一定的偏差而导致 产品尺寸不准确。另一申请号为 201010240535. 8的中国专利申请文献中公开 一种热塑模杯修边装置， 包括一底座、 寻边导向装置和切刀装置， 由驱动电 机带动寻边导向装置上的连接杆沿预定的轨迹运动， 从而带动切刀装置完成 修边工作， 但是这种结构中切刀装置需要沿着预定的轮廓线轨迹切割一周才 能完成加工， 需要较长时间， 效率也不高； 同时上述连接杆由一弹性件来支 撑， 切刀装置在切割过程中容易偏离， 导致剪裁精度达不到要求。 发明内容

本发明所采用的技术方案是： 本发明涉及的模杯修边装置包括用于定位 模杯半成品的下模和位于该下模的上方用作冲裁的上模， 在所述下模上具有 至少一个冲裁区域， 并且该冲裁区域内设置有容纳所述模杯半成品的三维轮 廓的定位腔； 在所述上模的下表面上设有对应于冲裁区域的刀模， 所述刀模 的轮廓形状与该冲裁区域的边界相适配。
进一步， 在所述上模的下表面上设置有弹性材质的压垫， 该压垫的厚度 在自然状态下凸出于所述刀模。
进一步， 所述模杯修边装置还包括使下模水平移动的驱动装置， 该驱动 装置通过一伸缩杆与所述下模连接。
具体来说， 所述驱动装置可以选择气缸、 液压缸或电动机。
进一步， 所述下模包括砧板和砧板底座， 所述伸缩杆连接于该砧板底座 上， 所述冲裁区域以及定位腔设于该砧板上。
进一步， 在所述砧板上设有至少两个定位柱， 该定位柱与模杯半成品上 预留的定位孔相适配。 进一步， 所述定位腔为开设于下模上的孔或者与模杯半成品的三维轮廓相适 应的凹坑。
进一步， 所述上模连接于液压系统。 本发明的有益效果是： 由于本发明的下模上具有至少一个冲裁区域， 并 且该冲裁区域内设置有容纳所述模杯半成品的三维轮廓的定位腔； 在所述上 模的下表面上设有对应于冲裁区说域的刀模， 所述刀模的轮廓形状与该冲裁区 域的边界相适配， 这样可以一次性完成加工， 保证了高效率； 同时由于刀模 固定在上模， 且下模上的砧板位置固定使得书刀模每次冲压在砧板的同一位置 上， 从而使得砧板上永远只有一个刀模印， 避免手工放刀模冲花砧板导致冲 切不断的现象， 不仅保证了冲裁的准确度， 而且使得砧板能够经久耐用。 此 外由于模杯半成品 （未修边的模杯） 在模压时预留有定位孔， 配合砧板上的 定位柱， 使得模杯半成品准确定位在砧板上， 而砧板上的定位腔设计将模杯 的三维轮廓容纳于内， 使得三维的模杯轮廓线以外部分接近二维， 再加上刀 模附件凸出的压垫设计， 在冲裁过程中将三维的模杯轮廓线以外部分完全压 成平面， 保证了刀模对边角的冲切尺寸准确无误。 另外， 所述模杯修边装置还包括使下模水平移动的驱动装置， 该驱动装 置通过一伸缩杆与所述下模连接， 该驱动装置可以选择气缸、 液压缸或电动 机， 它可以将下模的砧板推送到准确位置上进行冲裁， 冲裁完成之后将砧板 拉离刀模的正下方， 不仅保证了加工精度， 而且保证了操作人员在上料和卸 料时的安全性。 说 明 书

图 2是本发明中下模被推送至冲裁位置的示意图；
图 3是本发明中下模上放置有模杯半成品时俯视图；
图 4是本发明中装有刀模的上模的仰视图。 具体实施方式
以下以乳罩模杯半成品的修边加工为例，结合附图对本发明模杯修边装 置的具体实施方式做一个详细说明： 如图 1所示，本发明涉及的模杯修边装置包括用于定位模杯半成品 4的 下模 2和位于该下模 2的上方用作冲裁的上模 1， 上模 1连接液压系统， 可 以作上下升降运动， 下模 2是位于模杯修边装置的底座 3上。 在所述上模 1 的下表面上设有用于切割的刀模 7， 所述下模 2—般来说是包括砧板 201和 砧板底座 202， 砧板 201上设置有至少一个定位腔， 用于容纳模杯半成品 4 (未修边的模杯） 的三维轮廓 401， 当模杯半成品 4定位于下模 2时， 三维 轮廓 401被藏于定位腔中， 位于三维轮廓 401边缘的边角 402被布置在砧板 201的上表面， 方便上模 1上的刀模 7裁切， 其中边角 402即是本发明的修 边装置中提及的需要修掉的部分； 所述定位腔的数量根据一次加工的模杯的 数量来设定， 该定位腔可以是开设于砧板 201上的孔或者与模杯半成品 4的 三维轮廓 401相适应的凹坑； 为了简化砧板 201的制作工艺， 在本实施例中， 砧板 201上的定位腔是设计成两个孔 203， 对应于模杯半成品 4上的两个罩 杯； 在所述砧板 201上还设有至少两个定位柱 5， 该定位柱 5与模杯半成品 4 上在模压时预留的定位孔相适配， 因此在模杯半成品 4的定位上， 主要是依 告 ΤΤΤΐ Ν^Ι ηη Ι Τ¾ ^ /Λ· ^ ήΛ ^ /Λ· Λτ ΡΉ μ 士 Ί¾Γ ο tr^ nfe ο μ /Λ· ¾ ΤΤΤ I 是固定的， 也可以是相对可动的； 若下模 2是固定设置在上模 1的正下方， 则在这种情况下操作人员需要在刀模 7的下方来装卸产品， 这样在装卸过程 中由于误操作可能会启动液压系统使上模 1工作而导致发生危险事故， 这是 这种安装方式的缺陷之一。
如图 2所示， 为了提高本装置的安全性能， 可以使下模 2相对底座 3是 相对滑动的， 在原有基础上增加说了使下模 2水平移动的驱动装置， 该驱动装 置通过一伸缩杆 6与砧板底座 202的连接， 所述驱动装置为现有技术中的选 择， 可以是驱动气缸、 液压缸或步进电机等。 以本实施例中的驱动气缸 9为
书
例来说明， 在开始时砧板 201没有位于刀模 7的下方 （如图 1所示的状态）， 此时可将模杯半成品 4放置在砧板 201上， 并用定位柱 5来定位， 然后启动 驱动气缸 9的开关， 通过收缩伸缩杆 6拉动砧板底座 202以及砧板 201， 砧 板底座 202沿着底座 3的平面作水平运动， 砧板 201被拉送到刀模 7下的准 确位置 （如图 2所示的状态）， 接下来上模 1启动完成冲裁的过程。
如图 3所示的下模 2的俯视图， 其中砧板 201通过固定块 11连接在伸 缩杆 6上， 砧板 201由伸缩杆 6推送到不同的工位。 具有一对罩杯的模杯半 成品 4被定位在砧板 201上，其三维轮廓 401位于孔 203内，多余的边角 402 位于砧板 201的上表面上， 并用两个定位柱 5来定位。 砧板 201上划分有两 个对应罩杯部位的冲裁区域 10， 两个孔 203分别位于这两个冲裁区域 10内， 当刀模 7向下冲裁时， 正好按照冲裁区域 10的边界来裁切， 去除周围的边角 402 (即阴影部分）， 而且是一次性完成， 裁切完成后得到两个修好边的成品。
如图 4所示的上模 1的仰视图，可以看出上模 1的下表面上刀模 Ί的轮 廓形状与砧板 201上冲裁区域 10的边界相适配，这样可以保证刀模 7能够准 确的一次性切割出冲裁区域 10上预设的形状。在所述上模 1的下表面上还设 置有弹性材质的压垫 8， 压垫 8可以采用橡胶、 软性塑料等可以回弹的弹性 材料， 该压垫 8的厚度在自然状态下凸出于所述刀模 7 (见图 1中）， 并且压 垫 8通过粘贴固定于刀模 7轮廓的内侧以及外围。
本实施例在正式实施冲裁前需要确保： 刀模 7是否已按制造好冲裁区域 10的边界线安装好， 并调试固定说安装在上模 1上； 普通砧板是否已按罩杯轮 廓开好孔 203形成本发明的砧板 201， 砧板 201上的定位柱 5是否已按模杯 半成品 4上的预留定位孔尺寸距离安装好； 上模 1上凸出的压垫 8是否已按
书
刀模 7的轮廓粘紧在刀模 7的里侧及四周； 砧板 201是否已稳固安装在伸宿 杆 6连接的砧板底座 202上。 上述措施就绪后， 将已预留定位孔的模杯半成 品 4套到图 1所示的砧板 201上的定位钉 5上， 启动开关， 伸宿杆 6将砧板 201准确迅速拉送到刀模 7下方的准确位置 （图 2所示位置） 进行冲裁， 冲 裁过程中， 刀模 7附近凸出的压垫 8首先接触模杯半成品 4， 将三维轮廓 401 以外的部分完全压平在砧板 201的上平面上，同时压垫 8由于受压变形压缩， 使得刀模 7露出来， 然后刀模 7按照冲裁区域 10的形状完成冲裁。冲裁之后 伸宿杆 6将砧板 201迅速回送到图 1所示的下料区， 到此即完成一个工作循 环， 一对左右对称、 尺寸准确的模杯在短短大约十二秒之内就可完成了整个 修边过程。另外由于本实施例利用液压系统带动刀模， 具有冲裁准确的优点， 配合以上各种定位装置， 可以将尺寸误差控制在 +/_lmm以内， 也可以将修边 效率提高到液压机冲裁的极限次数， 达到每分钟可冲裁五次， 如果以每次修 边两对计算，则每分钟就可以完成修边 10对，真正体现了本发明的高效率性。
