一种复合板、复合板毛化设备及制造方法 技术领域
本发明涉及金属板材技术领域，尤其涉及一种复合板、复合板毛化设备及制造方法。
背景技术
随着智能时代的到来，人们对手机的需求量大大提升，为得到更多消费者的喜爱，手机制造商也在绞尽脑汁在各个零件上进行创新与设计。手机盖板作为手机的一个组成零件，其生产制造过程中的各种工艺验证和方法尝试也是几经波折，其中工艺的加工过程是极其关键的，采用何种工艺会直接影响其良品率以及生产效率。
钢/铝复合板具有钢的高强度和良好塑性，以及铝的良好导电性、导热性、耐蚀性和密度小等优点。钢/铝复合板用于轨道交通领域的地铁接触轨，汽车和高速列车的车身材料，以及发动机的轴瓦材料。利用铝的良好导热性，市场上还推出了多种钢/铝复合材质的散热片和锅具。此外，钢/铝复合板在机械、船舶、核能、电力等许多领域也得到了广泛的应用，尤其随着智能手机与5G技术的发展，钢/铝复合板也由于其特有的性质被应用到了智能手机边框的生产上。

下面结合图1-图6描述本发明实施例的复合板、复合板毛化设备及制造方法。
如图1至图3所示，复合板包括第一板体5和第二板体16，第一板体5的第一侧面形成有条纹14，第二板体16的第一侧面与第一板体5的第一侧面轧制连接，相邻两个所述条纹14之间的距离为0.005-0.03mm的所述条纹14在条纹总数中占比大于90％。经过测试当相邻两个所述条纹14之间的距离为0.005-0.03mm的所述条纹14在条纹总数中占比大于90％时，复合板的剪切强度在210Mpa-245Mpa之间。
本发明实施例提供的复合板，通过对第一板体5的第一侧面进行毛化处理，使得第一板体5的第一侧面或者第二板体16的第一侧面形成条纹14，增大第一板体5与第二板体16轧制时的面积，使得第一板体5与第二板体16复合之后的复合板结合强度更高，结合更牢 固。
根据本发明的实施例，相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于90％。条纹14越均匀且相邻两个条纹14之间的距离越小，单位面积条纹数越多，第一板体5与第二板体16轧制时的面积越大，使得第一板体5与第二板体16复合之后的复合板结合强度更高。经过测试当相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于90％时，复合板的剪切强度在200Mpa-230Mpa之间。
根据本发明的实施例，相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于80％。经过测试当相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于80％时，复合板的剪切强度在190Mpa-225Mpa之间。
根据本发明的实施例，相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于70％。经过测试当相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于70％时，复合板的剪切强度在185Mpa-220Mpa之间。
根据本发明的实施例，相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于50％。经过测试当相邻两个所述条纹14之间的距离为0.01mm-0.02mm的条纹14在条纹总数中占比大于50％时，复合板的剪切强度在170Mpa-210Mpa之间。
根据本发明的实施例，条纹14为直线条纹，直线条纹间隔设置，相邻两个条纹14之间的距离可以相等，也可以不相等。
这里需要说明的是，本发明实施例的条纹14是指在第一板体5的第一侧面和/或第二板体16的第一侧面形成的沟槽，沟槽的深度由毛化摩擦辊3工作时受到的压力决定。
根据本发明的实施例，第一板体5呈长条形，条纹14的长度方向与第一板体5的宽度方向之间成预设夹角，本实施例中预设夹角可 以但是不局限为70°-82°。第一板体5的条纹14用于增大第一板体5与第二板体16轧制时的接触面积。
根据本发明的实施例，第二板体16的第一侧面也形成有条纹14，条纹14的长度方向与第二板体16的宽度方向之间成预设夹角，本实施例中预设夹角可以但是不局限为70°-82°。第二板体16的条纹14对应的预设夹角与第一板体5的条纹14对应的预设夹角可以相等，以确保轧制时第一板体5与第二板体16之间可以更好地耦合。第二板体16的条纹14用于在轧制复合板过程中排出空气，由于条纹14的长度方向与第二板体16的宽度方向之间成预设夹角，因此条纹14的长度较短。在第一板体5与第二板体16轧制时条纹14越短，越有利于将第一板体5与第二板体16之间的空气排走，使得复合板的结合强度更高。
根据本发明的实施例，第一板体5的硬度大于第二板体16的硬度，由于第二板体16的硬度较小，在轧制过程中第二板体16会发生变形，第二板体16会进入第一板体5的条纹14的沟槽内，待第一板体5冷却后，条纹14之间的距离缩小，第二板体16在条纹14的沟槽内与第一板体5紧密贴合，构成过盈配合，从而将第一板体5与第二板体16紧密结合在一起。
本发明实施例中的硬度HV就是维氏硬度，单位为kg/mm2。维氏硬度定义为：将正四棱锥金刚石压头以一定的载荷压入试样表面并保持一定的时间后卸载试验力，所使用的载荷与试样表面上形成的压痕的面积之比。
根据本发明的实施例，第一板体5为钛板，第二板体16为铝合金板，当然第一板体5与第二板体16的材质并不限定于此，具体根据实际需要进行确定。其中，钛板包括含有各种合金成分的钛板和含有各种非金属元素的钛板，或者，各种金相组织结构的钛板，当然第一板体5也可以为表面设有镀层的钢板；铝合金板包括含有各种合金 及各种成分配比的铝合金板体。
根据本发明的实施例，第一板体5的硬度为HV270-330，第一板体5的第一侧面的粗糙度为0.8-4.0Ra，第二板体16的第一侧面的粗糙度为4-10Ra，Ra为算术平均粗糙度。使用硬度较大的第一板体5进行符合，有效提高复合板的硬度，进而满足制作手机边框的需求。
根据本发明的实施例，复合板的剪切强度τ＝a*b*K1*K2*σ 软，a为第一板体5的长度，b为第一板体5的宽度，K1为第一板体5的毛化面积比，K1的取值范围为1.5-3；K2为第一板体5与第二板体16的结合率，K2的取值范围为0.15-0.3，当K1*K2＞1时，K1与K2的乘积均取值为1；σ 软为第二板体16的屈服强度，σ 软的取值范围为350-412Mpa。Mpa是压强的单位，m表示兆，pa表示帕斯卡。
下面结合图1、图2和图3描述本发明的一个具体实施例：图1和图2中，复合板包括第一板体5和第二板体16，第一板体5为钛板，第二板体16为铝合金板。钛板的第一侧面形成有条纹14，条纹14为直线条纹，直线条纹间隔设置。相邻两个条纹14之间的距离为0.02mm的条纹14在条纹总数中占比大于90％。钛板呈长条形，条纹14的长度方向与钛板的宽度方向之间成78°角，钛板的硬度为HV300，钛板的第一侧面的粗糙度为2Ra。
铝合金板的第一侧面也形成有条纹14，钛板与铝合金板的厚度比为1.5:1.0。铝合金板的条纹14也为直线条纹，直线条纹间隔设置。相邻两个条纹14之间的距离为0.02mm的条纹14在条纹总数中占比大于90％。铝合金板也呈长条形，条纹14的长度方向与铝合金板的宽度方向之间成78°，铝合金板的第一侧面的粗糙度为3Ra。
铝合金板的第一侧面与钛板的第一侧面轧制连接形成复合板，复合板的剪切强度τ＝a*b*K1*K2*σ 软，a为钛板的长度，b为钛板的宽度，K1为钛板的毛化面积比，K1的取值范围为2；K2为钛板与铝合金板的结合率，K2的取值范围为0.2，当K1*K2＞1时，K1与K2的乘积 均取值为1；σ 软为铝合金板的屈服强度，σ 软的取值范围为380Mpa。
本发明实施例提供的复合板，通过对第一板体5的第一侧面进行毛化处理，使得第一板体5的第一侧面和/或者第二板体16的第一侧面形成条纹14，增大第一板体5与第二板体16轧制时的面积，使得第一板体5与第二板体16复合之后的复合板结合强度更高，结合更牢固。本发明实施例轧制的复合板的剪切力很大，复合板的结合严密，符合设计要求。加工出的复合板结合牢固，方便作为边框加工，应用于手机盖板的制作时，满足手机信号屏蔽程度小且强重比低等多方面要求。
本发明还提供一种复合板毛化设备，如图4和图5所示，该复合板毛化设备用于上述任意一项实施例所述的复合板的制造，复合板毛化设备包括毛化装置，毛化装置包括机体、第一驱动机构和至少一个毛化摩擦辊3，毛化摩擦辊3可转动地设置于机体，毛化摩擦辊3用于对第一板体5的第一侧面或者第二板体16的第一侧面进行摩擦。毛化摩擦辊3的轴线与第一方向之间呈预设夹角，本实施例中预设夹角为70°-90。第一驱动机构用于驱动毛化摩擦辊3轴向转动，第一驱动机构包括第一电机和第一传动机构，第一电机的转轴通过第一传动机构与毛化摩擦辊3连接，第一传动机构可以为皮带与皮带轮的组合，也可以为齿轮与链条的组合，还可以为多个齿轮的组合，且第一传动机构的具体结构形式不受此处举例限制，只要可以带动毛化摩擦辊3转动即可。
这里需要说明的是，如图4所示，第二方向为图4中的左右方向，第一方向为图4中的前后方向。毛化装置工作时，第一板体5或者第二板体16沿第二方向运动，并与毛化摩擦辊3接触，转动的毛化摩擦辊3在对第一板体5的第一侧面或者第二板体16的第一侧面进行摩擦，使得第一板体5的第一侧面或者第二板体16的第一侧面形成条纹14。
根据本发明的实施例，毛化摩擦辊3包括砂带，砂带的沙粒目数为40-120，砂带线速度：9-10m/S，第一板体速度4-6m/min，砂带压下重叠量0.02mm，砂带支撑滚轮材质橡胶，硬度HS60-75。砂带工作时受到的压力决定了条纹14的深度和数量，砂带的沙粒目数决定了条纹14的宽度。
根据本发明的实施例，毛化装置还包括除尘组件，除尘组件包括除尘辊4和第二驱动机构，除尘辊4可转动地设置于机体，除尘辊4的轴线沿第一方向延伸。毛化摩擦辊3与除尘辊4沿第二方向依次间隔排列，每个毛化摩擦辊3与除尘辊4的上方均设置有两个与机体转动连接的支撑辊11，两个支撑辊11间隔设置。支撑辊11用于与毛化摩擦辊3以及除尘辊4配合，对进行毛化处理的第一板体5或者第二板体16起到限位作用，确保毛化摩擦辊3和除尘辊4分别与板体接触良好。第二驱动机构用于驱动除尘辊4轴向转动，第二驱动机构包括第二电机和第二传动机构，第二电机的转轴通过第二传动机构与除尘辊4连接。第二传动机构可以为皮带与皮带轮的组合，也可以为齿轮与链条的组合，还可以为多个齿轮的组合。除尘辊4为毛刷辊，除尘辊4通过与第一板体5的第一侧面或者第二板体16的第一侧面接触，可以除去第一板体5或者第二板体16的表面的碎屑。
在毛化装置工作过程中，首先通过毛化摩擦辊3对第一板体5的第一侧面或者第二板体16的第一侧面进行毛化，再通过除尘辊4除去第一板体5或者第二板体16的表面的碎屑，保证毛化后的第一板体5或者第二板体16的表面洁净，然后再进行后续的轧制等工作。
这里需要说明的是，本实施例中除尘辊4只设置有一个，当然也可根据实际需要设置两个或者更多的除尘辊4。碎屑包括但不限定于金属碎屑和灰尘，还可以为其他物质。

根据本发明的实施例，毛化装置还包括升降组件10，升降组件10与毛化摩擦辊3连接，升降组件10用于改变毛化摩擦辊3的高度。由于毛化摩擦辊3与第一板体5或者第二板体16摩擦一段时间后，毛化摩擦辊3的外径会减小，这样就造成毛化处理形成的条纹14数量无法达到设计要求。因此需要通过升降组件10增大毛化摩擦辊3的高度，使得毛化摩擦辊3与第一板体5的第一侧面或者第二板体16的第一侧面充分接触。本实施例中升降组件10为伺服电机与丝杆组成的丝杆组件，丝杆组件的滑块与毛化摩擦辊3连接，通过伺服电机驱动丝杆转动，进而推动毛化摩擦辊3上下滑动，进而改变毛化摩擦辊3的高度。当然，升降组件10的类型并不限定于此，只要可以带动毛化摩擦辊3即可。

毛化装置包括机体、第一驱动机构、两个毛化摩擦辊3、除尘组件、壳体和升降组件10，机体设置于壳体的内部，两个毛化摩擦辊3可转动地设置于机体，毛化摩擦辊3用于对第一板体5的第一侧面或者第二板体16的第一侧面进行摩擦，毛化摩擦辊3的轴线与第一方向之间呈预设夹角，本实施例中预设夹角为80°。第一驱动机构包括第一电机和第一传动机构，第一电机的转轴通过第一传动机构与毛化摩擦辊3，第一传动机构可以为皮带与皮带轮的组合，也可以为齿轮与链条的组合，还可以为多个齿轮的组合。
除尘组件包括除尘辊4、第二驱动机构、吸尘器12和喷气口13，除尘辊4可转动地设置于机体，除尘辊4的轴线沿第一方向延伸。毛化摩擦辊3与除尘辊4沿第二方向依次间隔排列，除尘辊4位于两个毛化摩擦辊3的右侧。毛化摩擦辊3与除尘辊4的上方均设置有两个与机体转动连接的支撑辊11，两个支撑辊11间隔设置。支撑辊11用于与毛化摩擦辊3以及除尘辊4配合，对第一板体5或者第二板体16起到限位作用，确保毛化摩擦辊3和除尘辊4分别与板体接触良好。第二驱动机构用于驱动除尘辊4轴向转动，第二驱动机构包括第二电机和第二传动机构，第二电机的转轴通过第二传动机构与除尘辊4连接，第二传动机构可以为皮带与皮带轮的组合，也可以为齿轮与链条的组合，还可以为多个齿轮的组合。除尘辊4为毛刷辊，除尘辊4通过与第一板体5的第一侧面或者第二板体16的第一侧面接触，除去第一板体5和/或第二板体16的表面的碎屑。
在毛化装置工作过程中，首先通过毛化摩擦辊3对第一板体5的第一侧面或者第二板体16的第一侧面进行毛化，再通过除尘辊4除去第一板体5或者第二板体16的表面的碎屑，保证毛化后的第一板体5或者第二板体16的表面洁净，然后再进行后续的轧制等工作。

壳体内部间隔设置有两个隔板7，两个隔板7将壳体的内部分隔成三个腔室6，两个毛化摩擦辊3一一对应地设置于两个腔室6内，除尘辊4设置于剩余一个腔室6内。相邻两个腔室6之间的隔板7上设置有通孔，通孔便于第一板体5和第二板体16通过。通过设置隔板7将壳体的内部分隔成多个空间较小的腔室6，增强了吸尘器12的除尘效果。
升降组件10与毛化摩擦辊3连接，升降组件10用于改变毛化摩擦辊3的高度。由于毛化摩擦辊3对第一板体5的第一侧面或者第二板体16的第一侧面毛化处理一段时间后，刷丝会磨损，毛化摩擦辊3的外径减小，导致毛化处理产生的条纹14数量无法达到设计要求。因此需要通过升降组件10提高毛化摩擦辊3的高度，使得毛化摩擦辊3与第一板体5的第一侧面或者第二板体16的第一侧面充分接触。本实施例中升降组件10为伺服电机与丝杆组成的丝杆组件，丝杆组件的滑块与毛化摩擦辊3连接，通过伺服电机驱动丝杆转动，进而推 动毛化摩擦辊3上下滑动，进而改变毛化摩擦辊3的高度。当然，升降组件10的类型并不限定于此，升降组件10还可以为其他类型的升降机构。
检测装置包括控制终端8、控制器9和摄像头2，摄像头2位于第一板体5或者第二板体16的下方，且朝向第一板体5的第一侧面或者第二板体16的第一侧面，摄像头2用于获取第一板体5的第一侧面或者第二板体16的第一侧面的图像信息。控制器9与升降组件10电连接，控制器9用于控制升降组件10的工作与停止。控制终端8分别与控制器9以及摄像头2电连接，控制终端8用于确定第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数大于对应的预设值，还用于确定第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数小于对应的预设值，并控制升降组件10增加毛化摩擦辊3的高度。
放卷装置1设置于毛化摩擦辊3背离除尘辊4的一侧，放卷装置1用于缠绕第一板体5或者第二板体16，并在张力控制装置15的牵引下释放第一板体5或者第二板体16。

本发明实施例提供的复合板毛化设备，通过对第一板体5的第一侧面进行毛化处理，使得第一板体5和第二板体16的至少其中一个 的第一侧面形成条纹14，增大第一板体5与第二板体16轧制时的面积，使得第一板体5与第二板体16复合之后的复合板结合强度更高，结合更牢固。使用本发明复合板毛化设备生产的复合板的剪切力很大，复合板的结合严密，符合设计要求。加工出的复合板结合牢固，方便作为边框加工，满足手机信号屏蔽程度小且强重比低等多方面要求。
本发明还提供一种用于如上任意一项实施例所述复合板的复合板制造方法，如图6所示，复合板制造方法包括以下步骤：
步骤100，通过毛化摩擦辊3对第一板体5和第二板体16的至少其中一个的第一侧面进行摩擦形成条纹14；
毛化处理就是在第一板体5和第二板体16的至少其中一个的第一侧面形成沟槽状的直线条纹。
毛化摩擦辊3在与第一板体5的第一侧面或者第二板体16的第一侧面接触的过程中，通过摩擦形成条纹14，由于毛化摩擦辊3是匀速转动，第一板体5与第二板体16沿着第二方向匀速运动，因此在第一板体5的第一侧面和第二板体16的第一侧面形成的条纹14为直线条纹，直线条纹间隔设置，且直线条纹与第一板体5或者第二板体16的宽度方向成预设夹角。相邻两个条纹14之间的距离为0.005-0.03mm的条纹14在条纹总数中占比大于90％。毛化处理可以进行一次，也可以进行两次或者更多次。
步骤200，对第一板体5与第二板体16进行异步轧制，得到复合板。
本实施例中对第一板体5的第一侧面和第二板体16的第一侧面均进行毛化处理，当然，也可只对第一板体5的第一侧面进行毛化处理。
所述毛化摩擦辊包括砂带线速度：9-10m/S，第一板体速度4-6m/min，砂带压下重叠量0.02mm，砂带支撑滚轮材质橡胶，硬度HS60-75。
根据本发明的实施例，相邻两个所述条纹之间的距离为0.005-0.03mm的所述条纹在条纹总数中占比大于90％。
根据本发明的实施例，在执行所述对所述第一板体5与所述第二板体16进行异步轧制的步骤之前，还执行以下步骤：
步骤110，除去第一板体5和第二板体16的至少其中一个的表面的碎屑。
在除尘辊4转动的过程中可除去第一板体5或者第二板体16的表面的碎屑，当第一板体5或者第二板体16运动至上下两行喷气口13之间时，喷气口13向第一板体5或者第二板体16喷射高速气流，将第一板体5或者第二板体16表面的碎屑进一步清除，使得第一板体5或者第二板体16的表面干净，确保摄像头2可以获取清晰的图像信息，避免对第一板体5与第二板体16复合产生影响。
根据本发明的实施例，在执行除去第一板体5和第二板体16的至少其中一个的表面的碎屑的步骤之后，还执行以下步骤：
步骤120，获取第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数；
摄像头2获取第一板体5的第一侧面或者第二板体16的第一侧面的图像信息，并将图像信息发送至控制终端8。
步骤130，确定第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数小于对应的预设值，控制升降组件10增加毛化摩擦辊3的高度。
当控制终端8确定第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数小于对应的预设值时，控制终端8向控制器9发送控制指令，控制器9根据控制指令控制升降组件10升高，增加毛化摩擦辊3的高度，使得毛化摩擦辊3与第一板体5的第一侧面或者第二板体16的第一侧面接触紧密。
确定第一板体5的第一侧面或者第二板体16的第一侧面的单位 面积条纹数大于对应的预设值。控制终端8根据获取的图像信息计算单位面积条纹数，当确定第一板体5的第一侧面或者第二板体16的第一侧面的单位面积条纹数大于对应的预设值时，说明毛化摩擦辊3与第一板体5的第一侧面或者第二板体16的第一侧面接触良好，无需增加毛化摩擦辊3的高度。
根据本发明的实施例，对第一板体5与第二板体16进行异步轧制的步骤，包括：
步骤210，对第二板体16进行加热；
在对第二板体16进行加热的过程中采用在线加热方式，具体可采用电涡流加热的方式，第二板体16的加热温度为250℃。采用在线加热方式，可以实现第一板体5的第一侧面与第二板体16的第一侧面在半熔状态轧制复合，进一步提高复合板的结合强度。
本发明实施例中的异步轧制是指，将钛板与铝合金板(即第一板体5与第二板体16)用上下轧辊碾压轧制成复合板的过程，碾压钛板的轧辊与碾压铝板的轧辊的转速采用不同的转速。
步骤220，对加热后的第一板体5与第二板体16进行异步轧制，使第二板体16的第一侧面与第一板体5的第一侧面轧制连接形成复合板。
对第一板体5与第二板体16轧制过程中采用异步轧制，第一板体5与第二板体16的厚度比为1.5:1.0，第一板体5对应的轧辊与第二板体16对应的轧辊的异速比为1：1.05，异步轧制的轧制压下率为20％-40％。
本发明实施例中对第二板体16采用在线加热方式，即对铝板采用加热方式，其目的在于使得钛板的表面的条纹14不变形。然后将钛板与硬度较低的受热铝合金板通过上下轧辊碾压在一起后，由于钛板的硬度远远大于铝合金板的硬度，因此在铝合金板与钛板相互复合的复合面上，铝合金板的第一侧面受热软化后将被压入钛表面的沟槽 内，同时铝合金板表面遇冷收缩，这样就可以使得钛板与铝合金板在沟槽的两侧紧密贴合在一起，构成过赢配合，由此即可形成钛板与铝合金板之间紧密的结合在一起。
根据本发明的实施例，在执行对加热后的第一板体5与第二板体16进行异步轧制的步骤之后，还执行以下步骤：
步骤230，对复合板进行固溶处理；
固溶处理包括加热阶段和冷却阶段，在加热阶段，将复合板放入固溶炉内进行固溶处理，固溶处理的固溶温度为250-450℃，固溶处理的固溶时间为45-65min。在冷却阶段，将复合板进行快速冷却，使得复合板最终冷却至常温。通过对复合板进行固溶处理，使得复合板的结合强度进一步提高。
步骤240，对固溶处理后的复合板进行时效处理。
复合板进行固溶处理后，还需要进行时效处理。时效处理在时效炉中进行，时效处理的时效温度为160-200℃，时效处理的时效时间为5-7h。通过对复合板进行时效处理，可进一步提高复合板的结合强度。
本发明实施例提供的复合板制造方法，通过对第一板体5的第一侧面进行毛化处理，使得第一板体5的第一侧面和/或者第二板体16的第一侧面形成条纹14，增大第一板体5与第二板体16轧制时的面积，使得第一板体5与第二板体16复合之后的复合板结合强度更高，结合更牢固。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
