本发明涉及薄板件加工设备技术领域，尤其是一种薄板件流体胀形设备。
背景技术
在新能源汽车电池、5G通讯基站等需要薄板件散热的领域，目前对于散热冷板成型基本上都是采用冲压成型，或者流体高压胀形等方式加工成型。其中流体胀形设备基本上采用和冲压设备相同的标准油压机，随着散热冷板产品的面积越来越大和要求的胀形力比较大的情况下，使用通用性设备的成本特别高，效率比较低，并且很多通用的附属部件(比如：拉延油缸等)用不上，造成投资浪费。
现有流体胀形设备基本上采用和冲压设备相同的标准油压机，把胀形模具的下模固定在工装台面上，上模固定在标准油压机滑块上，通过油压机的滑块向下运动，使上模和下模合模，通过延时或者单向阀关闭等方式压力保持，然后进行胀形操作，然后压力撤除，滑块上移，上模上移，开模进行去放产品。

具体实施方式
下面结合具体实施方式和说明书附图对本发明作进一步说明。
请参阅图1，一种薄板件流体胀形设备，包括主机构3和位于主机构3两侧的左右开模机构(2、5)以及左右移动工作平台(1、6)，主机构3包括主体框架和位于主体框架下方的主油缸，主油缸通过油路块连接有主缸锁模增压缸，设备安装后，主油缸位于地坑中；主机构3对应的是成型工位，左右开模机构(2、5)下方对应的为开模机构；本发明中的主体框架可以采用铸造主体框架，也可以采用钢板拼接主体框架。
主机构3的上方设置有液压控制系统4，液压控制系统4内有超高压发生装置，超高压发生装置通过管路与主缸锁模增压缸连接；液压控制系统4还与左右开模机构(2、5)连接，液压控制系统4主要用来控制主油缸、左右开模缸快速运行、主缸锁模增压缸等，胀形设备还包括电器柜，放置在设备的后上方，轴控制器、伺服系统、低压电气等控制系统用。
本发明中的胀形设备采用双工位模块化结构，可以有效提高工作效率。主油缸通过主缸锁模增压缸来驱动合模力，压力可调节，且显示精度达到2％，可长时间保压。移动工作台为钢板加工件，加工精度按相关标准执行，满足生产 需要，有足够的刚度和强度。
请参阅图2，本实施例中的左右开模机构(2、5)分别包括机架，机架上安装有液压缸，液压缸的端部连接有滑块10，滑块10的下表面设有T型挂钩，滑块10连接有位移传感器，滑块10行程控制采用位移传感器控制，确保滑块10在行程范围内安全工作，采用光栅保护和双手下下行等安全措施，光栅一边设置再开模机构支架上，另一边设置在主机架上。操作方式为手动单独操作和自动联机操作，通过传感器和电器柜里面的控制器实现与主机其它动作互锁。滑块10下平面设有T型挂钩，便于开合模及快速移动；滑块10的行程控制可通过位移传感器实现数显和数控。在行程区预先设定任意位置，使滑块10在变速运行中能平稳过度，无冲击现象产生。左右开模机构(2、5)以及左右移动工作平台(1、6)下方的底板8和滑轨9的机架型材采用二氧化碳气体保护焊，焊接后加工。T型挂钩也可以换成L型挂钩。上模具上有与挂钩形状相匹配的结构，当挂钩为T型时，上模具上开有L形块，当挂钩为L型时，上模具上有T形块与其对插实现挂钩与上模具的连接。
本实施例中的左右移动工作平台(1、6)安装在位于主体框架下方的底板8，底板8上连接有滑轨9，左右移动工作平台(1、6)分别连接有伺服电机，伺服电机驱动滑板沿滑轨9往复移动，移动工作台采用伺服移动，定位精度高；可进行手动、自动、换模等操作。
为了进一步提高生产过程的安全性，本实施例中的主机构3的两侧分别设置有一组防护板7或者防护光栅，每组防护板7或防护光栅分别对称设置在滑轨9的两侧，这样可以避免左右工作移动平台沿滑轨9往复移动的过程中有人进入轨道，从而提高生产安全性。
本实施例中的主油缸由若干小油缸构成，左右移动工作平台(1、6)底部 分别开有若干与小油缸相匹配的通孔，主油缸通过左右移动工作平台(1、6)底部的通孔对下模具施加压力，上模具的上端顶在主体框架的下表面，从而将模具压紧，从而实现零件的胀形成型，采用此结构设计，使得模具可以受力均匀，从而提高胀形质量。
本实施例中的主体框架通过螺栓与地坑中的预埋件连接固定，设备地基比较浅，并且地面上高度低，可以满足现有标准厂房的安装。
动作顺序：
第一次上模具，模具固定好后，移动工作平台要移动到成型工位，等开模T型挂钩下来后，再移出来让上模具上的L形块套到T型挂钩上，然后开模油缸(即开模机构的液压缸)上移开模，把产品原料(薄板料)放进去后，开模油缸(即开模机构的液压缸)再向下移动合模。合模结束，移动工作平台移动到成型工位成型。左右两个工位依次重复动作。
对于本领域技术人员而言，显然本发明不限于上述示范性实验例的细节，而且在不背离本发明的精神和基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的同等要件的含义和范围内的所有变化囊括在本发明内，不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的权利方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
