Description
本发明涉及橡胶履带生产用的设备，具体涉及适用多种节距规格的橡胶履带预成型用生产设备。
橡胶履带在硫化成型前，需要将铁齿（芯金）按规定的节距预先埋入橡胶内，在现有橡胶履带成型过程中，其方法是将橡胶铺在按履带规格节距设计的治具上，然后按规格节距放入铁齿，再铺上一层橡胶薄皮，用类似螺丝刀的尖状物靠人力沿铁齿长度方向边缘逐一戳下去，利用橡胶的粘性实现预成型，制得预成型件，再放入橡胶履带模具中，与骨架（例如：钢丝绳骨架）等一起硫化成型制得橡胶履带产品。这种预成型作业方式的缺点是：效率低下，且员工劳动强度大，铁齿定位节距不稳定，预成型效果不好，铁齿很容易掉出。为了克服这一问题，我公司研发了一款橡胶履带预成型设备，并获得了专利权（专利号ZL 201020257254.9）。该橡胶履带预成型设备可以代替人工，实现预成型目的，虽然具有生产效率高的特点，但是生产实践表明，这种设备还存在以下不足：即只能适用单一节距规格的橡胶履带的生产需求，不同节距的橡胶履带需要在不同的设备上完成，不具备通用性。
针对现有技术的不足，本发明提供了适用多种节距规格的橡胶履带预成型用生产设备。本发明的橡胶履带预成型用生产设备可以对不同节距规格的橡胶履带进行预成型件制造，通用性好。
适用多种节距规格的橡胶履带预成型用生产设备，包括机架，机架上设有相互配合使用的承载装置和压胶装置；所述承载装置包括可由往复驱动元件驱动在纵向上移动的承压板，承压板上设有芯金定位板，芯金定位板上按橡胶履带节距间隔设有芯金定位孔；所述芯金定位板以可更换的方式设置；对应的，所述压胶装置包括施压板，所述施压板与沿竖向设于机架上的至少一根导向杆通过滑动副联接形成导向配合，所述施压板可由设于其上方的升降驱动元件驱动做升降运动；所述施压板的下侧沿横向设有变导程多段组合丝杆，所述变导程多段组合丝杆包括一组依序相接的丝杆子段，第一个丝杆子段与可由丝杆驱动电机驱动的光轴段传动连接，第n个丝杆子段的导程是第一个丝杆子段的导程的n倍；所述光轴段上设有一个与其通过回转副结构连接的压头，同时，每一个丝杆子段上均通过螺旋副结构连接一个压头，形成等距分布的压头组；所有压头的顶部均与施压板滑动连接形成限制旋转的限位结构。
与现有技术相比，本发明的技术方案中，芯金定位板以可更换的方式设置，并采用特定构造的压胶装置，变导程多段组合丝杆转动时，由于第n个丝杆子段的导程是第一个丝杆子段的导程的n倍，第n个丝杆子段上的压头移动距离是第一个丝杆子段上的压头移动距离的n倍，使各压头始终保持等距分布，从而可以通过变导程多段组合丝杆驱动压头来适应不同节距规格的橡胶履带预成型生产需求，设备具有通用性。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：所述丝杆子段的前端和后端分别对应设有扭力传递头和扭力传递孔，相邻的两个丝杆子段通过扭力传递头和扭力传递孔的配合形成扭力传递结构实现传动连接。通过扭力传递头和扭力传递孔的配合实现传动连接，结构可靠，且易于制造。进一步，所述丝杆子段上，在设有扭力传递孔的一端，对应设有螺纹孔；相邻两个丝杆子段通过安装于螺纹孔中螺钉锁紧。通过螺钉锁紧，可以进一步提高连接结构的可靠性。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：相邻的两个丝杆子段之间设有一个挡片。通过设置挡片，装配时，只需要将压头调节至与挡片相抵靠，即可实现压头的等距分布，使得装配难度得到降低。进一步，所述挡片可以通过其两侧的两个丝杆子段端面的压紧作用实现固定。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：所述压头包括与变导程多段组合丝杆联接的基块，基块的下侧设有可以在竖向上浮动并由弹簧力复位的缓冲压块；所述基块的下表面设有成组分布的压针，对应的，所述缓冲压块上成组设有针孔，在缓冲压块向上浮动时，压针从针孔中伸出。压头采用这种结构，缓冲压块的缓冲功能，起到保护作用。进一步，所述基块的下表面设有两排沿纵向分布的压针。通过在基块的下表面设置两排沿纵向分布的压针，压针数量多，且预成型时，压针与邻近铁齿的距离更近，有利于提高预成型质量。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：所述升降驱动元件可以为液压缸。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：所述施压板的上侧表面设有一组加强筋。通过设置加强筋可以提高施压板的刚性，延长使用寿命。
作为优化，前述的适用多种节距规格的橡胶履带预成型用生产设备中：所述承载装置具有两个，分别设于施压板下方位置的两侧。由此，可以在其中一个承压装置执行预成型任务时，在另一个承压装置上进行上料，有利于提高生产效率。进一步，两个承载装置可以共用一套沿纵向设置的导轨。

下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。以下实施例中，未详细说明的均为本领域常规技术手段或技术常识。
参见图1-7，本发明的适用多种节距规格的橡胶履带预成型用生产设备，包括机架1，机架1上设有相互配合使用的承载装置和压胶装置；所述承载装置包括可由往复驱动元件驱动在纵向上移动的承压板2，承压板2上设有芯金定位板3，芯金定位板3上按橡胶履带节距间隔设有芯金定位孔301；与现有技术不同的是，本发明设备中，所述芯金定位板3以可更换的方式设置；对应的，所述压胶装置包括施压板4，所述施压板4与沿竖向设于机架上的至少一根导向杆5通过滑动副联接形成导向配合，所述施压板4可由设于其上方的升降驱动元件6驱动做升降运动；所述施压板4的下侧沿横向设有变导程多段组合丝杆7，所述变导程多段组合丝杆7包括一组依序相接的丝杆子段701，第一个丝杆子段701与可由丝杆驱动电机9驱动的光轴段702传动连接，第n个丝杆子段701的导程是第一个丝杆子段701的导程的n倍（即第一个丝杆子段701的导程为P，第二个丝杆子段701的导程为2P，第三段丝杆子段701的导程为3P，依此类推；为制图方便，附图中，导程的变化未具体体现）；所述光轴段702上设有一个与其通过回转副结构连接的压头8，同时，每一个丝杆子段701上均通过螺旋副结构连接一个压头8，形成等距分布的压头组；所有压头8的顶部均与施压板4滑动连接形成限制旋转的限位结构。
本发明中，变导程多段组合丝杆7和压头组构成预成型执行机构，各压头8等距分布，安装于光轴段702上的压头8不能轴向移动，安装于丝杆子段701上的压头8可以在轴向上移动，由于变导程多段组合丝杆7中的第n个丝杆子段701的导程是第一个丝杆子段701的导程的n倍，丝杆驱动电机9驱动变导程多段组合丝杆7转动后，各压头8仍然是等距分布。需要预成型作业时，根据橡胶履带节距，安装或更换上适配的芯金定位板3，并通过变导程多段组合丝杆7调节压头8，使各压头8按照橡胶履带节距分布。
实施例：
本实施例中，所述丝杆子段701的前端和后端分别对应设有扭力传递头7011和扭力传递孔7012，相邻的两个丝杆子段701通过扭力传递头7011和扭力传递孔7012的配合形成扭力传递结构实现传动连接。工作时，前一个丝杆子段701通过扭力传递结构带动后一个丝杆子段701转动。在本实施例中，光轴段702与变导程多段组合丝杆7的第一个丝杆子段701也通过这种结构传动连接。
本实施例中，所述丝杆子段701上，在设有扭力传递孔7012的一端，对应设有螺纹孔7013；相邻两个丝杆子段701通过安装于螺纹孔7013中螺钉锁紧（为制图方便，附图中未画出螺钉）。从而，使得可靠性得到进一步提高。
本实施例中，相邻的两个丝杆子段701之间设有一个挡片703。通过设置挡片703，组装时，让压头8与对应丝杆子段701前端的挡片703相抵即可保证压头组的各压头8等距分布（组装完成后的初始状态如图7所示，此时，相邻两压头8的间距为设备能够加工的最小节距）。本实施例中，光轴段702与变导程多段组合丝杆7的第一个丝杆子段701之间也设有一个挡片703。
本实施例中，所述挡片703通过其两侧的两个丝杆子段701的端面压紧作用实现固定。
本实施例中，所述压头8包括与变导程多段组合丝杆7联接的基块801，基块801的下侧设有可以在竖向上浮动并由弹簧力复位的缓冲压块802；所述基块801的下表面设有成组分布的压针803，对应的，所述缓冲压块802上成组设有针孔，在缓冲压块802向上浮动时，压针803从针孔中伸出。
本实施例中，所述基块801的下表面设有两排沿纵向分布的压针803。（本实施例中，每排各6个压针）
本实施例中，所述升降驱动元件为液压缸。升降驱动元件采用液压缸，可靠性好，且易于实施。
本实施例中，所述施压板4的上侧表面设有一组加强筋401。通过设置加强筋401可以防止施压板4变形。
本实施例中，所述承载装置具有两个，分别设于施压板4下方位置的两侧。两个承载装置共用导轨。通过设置两个承载装置，其中一个执行预成型作业时，可以在另一个承载装置上进行上料作业，从而可以提高生产效率。
实施本发明方案时，一台设备可以设置多个预成型执行机构。在本实施例中，施压板4的下侧设有两个预成型执行机构，两个预成型执行机构的变导程组合丝杆7首尾相连形成传动连接，前一个变导程组合丝杆7由丝杆驱动电机9直接驱动，并将扭力传递给后一个变导程组合丝杆7。本实施例通过设置两个预成型机构，一个下压动作，可以制得两个预成型件。本实施例中，变导程组合丝杆7具有6个丝杆子段701，实施时本发明时，丝杆子段701的数量可以根据实际需求确定，丝杆子段701数量设计的少一些，可以使本发明设备获得更宽的节距调节范围。
上述对本申请中涉及的发明的一般性描述和对其具体实施方式的描述不应理解为是对该实用新型技术方案构成的限制。本领域所属技术人员根据本申请的公开，可以在不违背所涉及的实用新型构成要素的前提下，对上述一般性描述或/和具体实施方式（包括实施例）中的公开技术特征进行增加、减少或组合，形成属于本申请保护范围之内的其它的技术方案。
