Description

开卷落料模具的板料输送机构 技术领域
本发明涉及一种开卷落料模具的板料输送机构,属于压力制造工艺装备技术领域。 背景技术
随着汽车工业的发展和进步, 汽车工业的竞争也日趋激烈。 当今, 各汽车厂家为 了达到提高生产效率、 材料利用率、 产品质量等目的, 自动化开卷落料线在汽车行业 中逐步形成, 为汽车企业提高生产效率、 降低成本和提升质量带来直接的进步, 并开 始产生可观的经济效益。 压机动作一次落出两片落料片的工艺称为 "一出二" 工艺。
"一出二" 工艺极大的提高了生产效率和材料利用率。 但是, 目前的开卷落料线由于 工艺的限制, 开卷落料模具的板料输送机构采用的都是电机驱动或者电磁驱动, 此两 种驱动结构制造和维护成本都比较高, 在某种程度上限制了了 "一出二"工艺的实现, 导致了现在 "一出二" 工艺应用非常少, 因而有必要改进。 发明内容
本发明所要解决的技术问题是针对现有技术的不足, 提供一种开卷落料模具的板 料输送机构, 其具有结构简单、 制造工艺简单的优点, 节省投资; 此外还具有使用简 便、 工作可靠、 使用寿命长、 维护成本低等优点, 便于推广, 实用性和通用性均较强。
本发明所要解决的技术问题, 是通过如下的技术方案实现的:
一种开卷落料模具的板料输送机构, 包括: 推力摆臂、 轴销、 推力摆臂座和气缸 滑动组件; 所述气缸滑动组件水平设置, 推力摆臂座固定在气缸滑动组件的可动部分 上; 所述推力摆臂通过所述轴销可转动的设置在推力摆臂座上, 且轴销水平设置, 轴 销的轴线与气缸滑动组件的运动方向垂直。
本发明的有益效果在于: 由于采用气缸驱动, 相比现有技术中采用电机驱动或者 电磁驱动的板料输送机构, 具有结构简单、 制造工艺简单的优点, 因而能节省投资; 此外还具有使用简便、 工作可靠、 使用寿命长、 维护成本低等优点, 因而便于推广, 实用性和通用性均较强。
以下将结合附图和实施例, 对本发明的技术方案进行较为详细地说明。 附图说明
图 1为本发明开卷落料模具的板料输送机构的主视图;
图 2为本发明开卷落料模具的板料输送机构的俯视图;
图 3为本发明开卷落料模具的板料输送机构的另一主视图;
图 4为本发明落料片与开卷落料模具的板料输送机构在俯视方向的位置关系图; 图 5为本发明第二片开卷落料片 L2与开卷落料模具的板料输送机构在主视方向 的位置关系示意图。 具体实施方式
图 1和图 2分别为本发明开卷落料模具的板料输送机构的主视图和俯视图。 如图
1和图 2所示, 本发明提供一种开卷落料模具的板料输送机构, 包括: 推力摆臂 1、 轴 销 2、 推力摆臂座 3、 气缸滑动组件 4。 推力摆臂 1通过所述轴销 2可转动的设置在推 力摆臂座 3上。 而推力摆臂座 3固定在气缸滑动组件 4的可动部分上, 气缸滑动组件 4水平设置。 轴销 2水平设置, 且轴销 2的轴线与气缸滑动组件 4的可动部分运动方 向垂直, 推力摆臂 1的重心位于轴销 2轴线的一侧, BP : 以轴销 2为界, 推力摆臂 1 的一头较重, 为配重端 11 ; 另一头较轻, 为工作端 12。 在本实施例中, 具体而言是图 1中推力摆臂 1的左端为配重端 11, 右端为工作端 12。
气缸滑动组件 4上设置有进气孔和出气孔, 分别通过气管与高压气源可控连接。 本实施例中, 进气孔和出气孔与压机的气源连接, 因而可随压机的动作而有规律的进 气、 出气, 从而驱动推力摆臂座 3, 带着推力摆臂 1在水平方向的一定范围内做往复 直线运动。 如图 1所示, 为推力摆臂座 3运动至最左端的初始位置时的状态。 图 3为 本发明开卷落料模具的板料输送机构的另一主视图, 如图 3所示, 为推力摆臂座 3运 动至最右端末端位置时的状态。 此外, 由图 1对比图 3可见, 气缸滑动组件 4通过推 力摆臂座 3带着推力摆臂 1做往复直线运动的同时,推力摆臂 1还会因为惯性和重力, 在一定范围内绕销轴 2摆动。根据工作端 12接触落料片的位置, 推力摆臂 1的形状和 尺寸, 以及与开卷落料片之间的位置, 可以控制推力摆臂 1的摆动角度, 本实施例中, 推力摆臂 1的摆动角度, 即推力摆臂 1与推力摆臂座 3的夹角为 15度。角度主要取决 于工作端 12和板料接触位置的高度, 一般可选 10度至 30度之间, 优选 12度至 20 度之间, 在本实施例中, 更优选 15度, 实验证明, 该角度能获得很好的效果。
图 4 为本发明开卷落料片与开卷落料模具的板料输送机构俯视方向的位置关系 图。 由图 4可见, 在本实施例中, 板料沿图示 FEED方向输送过来, 开卷落料模具的 板料输送机构安装在 "一出二" 模具的第二片开卷落料片 L2 下面; 且在 "一出二" 的开卷落料片下, 布置了两组开卷落料模具的板料输送机构(其中位置 S1为气缸的初 始位置, 位置 S2为气缸的末端位置), 从而可以将第二片开卷落料片 L2从 "一出二" 模具推出到开卷落料线的传送皮带 5上, 实现第二片开卷落料片 L2的顺利出料。 在 本实施例中, 具体而言, 压机在 135度完成出气 (180度为压机的下死点, 360度为压 机的上死点), 使气缸回到最左端的初始位置, 在 185度的时候开始进气, 使气缸从最 左端位置运动到最右端的位置, 实现第二片开卷落料片 L2的输送。 由图 4可见, 第 一片开卷落料片 L1处于开卷落料线设备的传送皮带 5上, 因此可以被直接传送出去。
图 5为本发明第二片开卷落料片 L2与开卷落料模具的板料输送机构在主视方向 的位置关系图。 如图 5所示, 该附图尤其反映了推力摆臂座 3在三个代表性位置时, 第二片开卷落料片 L2和推力摆臂 1之间的位置关系; 其中 A为推力摆臂座 3 (或者说 气缸) 的初始位置, B为推力摆臂座 3的末端位置, C为推力摆臂座 3的中间位置。
由于气缸回复到初试位置 A时, 推力摆臂 1位于排样的第二片开卷落料片 L2的 空位上, 第二片开卷落料片 L2和推力摆臂 1不发生作用, 所以推力摆臂 1靠自身的 重力以及惯性, 绕轴销 2旋转 15度, 而翻转回到原来的位置, 为下一个工作循环做好 准备。
需要进一步说明的是, 推力摆臂 1和第二片开卷落料片 L2接触受力的位置, 即 推力摆臂 1的工作端必须要淬火, 一般要保证该处的强度在 HRC45以上, 以免长期工 作而严重磨损。 优选的技术方案中, 推力摆臂 1在复位过程中和第二片开卷落料片 L2 接触的部分, 即推力摆臂 1的工作端 12的顶部圆滑过度, 以避免划伤第二片开卷落料 片 L2。 另外, 气缸滑动组件 4的规格可以根据开卷落料片的尺寸和步距进行选择。
本发明的开卷落料模具的板料输送机构, 可广泛应用于所有的内板件或要求不高 的表面件的开卷落料模, 尤其适合应用于冲压 "一出二" 的开卷落料模上, 而且相比 现有技术中采用电机驱动或者电磁驱动的板料输送机构, 具有结构简单、 制造工艺简 单的优点, 因而能节省投资; 此外还具有使用简便、 工作可靠、 使用寿命长、 维护成 本低等优点, 因而便于推广, 实用性和通用性均较强。
以上内容是结合具体的优选实施例对本发明所作的进一步详细说明, 不能认定本 发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推演或替换, 都应当视为属于本 发明的保护范围。
