 本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
本发明一种复合钢塑板，如图2和图3所示，其包括压合在一起的内侧金属板10、塑料芯层20和外侧金属板30，其中内侧金属板10的长度和宽度分别与塑料芯层20的长度和宽度相同，这样使得内侧金属板10和塑料芯层20的边缘贴合；外侧金属板30的长度和宽度分别大于内侧金属板10和塑料芯层20的长度和宽度（即外侧金属板30的长度均内侧金属板10的长度和塑料芯层20的长度，外侧金属板30的宽度均大于内侧金属板10的宽度和塑料芯层20的宽度），内侧金属板10和塑料芯层20位于外侧金属板30的内部。
外侧金属板30大于内侧金属板10和塑料芯层20的加工区域31，通过塑性成型加工（具体加工方法为打凸包、抽芽、翻边成型、铆接螺柱、折弯卷圆、折边、折弯等），使得复合钢塑板成为一个兼并五金背板、中框、前框和内、外支撑板的五合一的一个钢塑模组背板。
其中，内侧金属板10设有至少一个内侧开孔11，塑料芯层20设有与内侧开孔11对应的塑料开孔21，内侧开孔11的尺寸不大于与塑料开孔21的尺寸（即内侧开孔11在外侧金属板30上的投影位于塑料开孔21在外侧金属板30上的投影的内部），且内侧开孔11和塑料开孔21上下对应设置。由于内侧金属板10和塑料芯层20分别裁切了内侧开孔11内的内侧金属板材料和塑料开孔21内的塑料材料，减轻了内侧金属板10和塑料芯层20的重量，尤其是局部去除了塑料芯层20的材料，这样就可以达到既保证其强度也可以保留金属材料的塑性功能，增加了金属材料的可塑性成型和应用功能，同步拓宽了外侧金属板30的加工区域（即外侧金属板30大于内侧金属板10和塑料芯层20的区域）材料的塑性应用。
在优选的实施例之一中，内侧开孔11和塑料开孔21均设有至少两个，两个内侧开孔11和两个塑料开孔21分别以内侧金属板10的中心线和塑料芯层20的中心线对称设置，这样可以达到整个复合钢塑板的对称。
在优选的实施例之二中，内侧开孔11和塑料开孔21设有一个，该内侧开孔11和塑料开孔21分别位于内侧金属板10的中心线和塑料芯层20的中心线上。
在优选的实施例之三中，内侧开孔11和塑料开孔21设有三个，其中两个内侧开孔11和两个塑料开孔21分别以内侧金属板10的中心线和塑料芯层20的中心线对称设置或位于中心线上，另外一个内侧开孔11和另外一个塑料开孔21分别位于内侧金属板10的中心线上和塑料芯层20的中心线上。
在优选的实施例之四中，内侧开孔11和塑料开孔21设有多个，多个内侧开孔11和多个塑料开孔21分别以所述内侧金属板10的中心线和塑料芯层20的中心线对称设置或位于中心线上。
内侧开孔11和塑料开孔21的数量和位置不做限制，只要分别开设在内侧金属板10和塑料芯层20上且上下对称设置，都属于本发明的保护范围。
压合形成复合钢塑板时，首先塑料芯层20的上表面和下表面分别加高分子膜（图未示），然后分别把内侧金属板10和外侧金属板30放置在塑料芯层20的上表面和下表面上，最后在专用设备下通过加温加压将三层材料（内侧金属板10、塑料芯层20和外侧金属板30）压合，压合时有起定位作用的模块（图未示）套住内侧金属板10和塑料芯层20，压合后再经冷却，此时得到一个塑料芯层20和内侧金属板10的中间局部分别冲孔裁切（即内侧开孔11和塑料开孔21），塑料芯层20和内侧金属板10均比外侧金属板30小一圈的复合钢塑板。
本发明还提供一种复合钢塑板的制造方法，包括如下步骤：
S1：准备一定厚度耐指纹金属板作为内侧金属板10，在内侧金属板10上裁切至少一个内侧开孔11；同时准备与内侧金属板10相同尺寸的塑料芯层20，在塑料芯层20上裁切与内侧开孔11对应的塑料开孔21，内侧开孔11的尺寸不大于与塑料开孔21的尺寸；
S2：准备外侧金属板30，外侧金属板30的尺寸均大于内侧金属板10和塑料芯层20的尺寸；
其中内侧金属板10、塑料芯层20和外侧金属板30都需要清洗干净，以去除表面油污和杂物；
S3：首先将外侧金属板30放置在压合机上，然后在外侧金属板30上放置与塑料芯层20的尺寸相同的第一张高分子膜，接着把塑料芯层20放置在第一张高分子膜上，然后在塑料芯层20上放置第二张高分子膜，最后把内侧金属板10放置在第二张高分子膜上；
S4：定位模块（图未示）固定塑料芯层20的位置；
S5：压合机（图未示）压合内侧金属板10、塑料芯层20和外侧金属板30；
S6：移走定位模块，得到复合钢塑板；
S7：对外侧金属板30的周围区域进行塑性成型加工（具体加工方法为打凸包、抽芽、翻边成型、铆接螺柱、折弯卷圆、折边、折弯等），使得复合钢塑板成为一个兼并五金背板、中框、前框和内、外支撑板的五合一的一个钢塑模组背板。
其中，步骤S7中，对外侧金属板30进行翻边加工后，外侧金属板30的加工区域与内侧金属板10和塑料芯层20之间仍有一定的间隙（此间隙为模具翻边加工而留）。
外侧金属板30的厚度优选为0.3-0.5mm，外侧金属板30的材料为VCM板材、铝材、不锈钢等其他外观材料；塑料芯层20的材料为ABS、PC、ABS+PC、PP蜂窝板等其他轻薄材料；内侧金属板10的厚度优选为0.3-0.510µm，内侧金属板20的材料为铝材、不锈钢等其他贴合材料；复合钢塑板的总厚度优选为1.2-5.0mm，通过调节塑料芯层20的厚度对复合钢塑板的厚度进行条件。
压合机的温度80-100度，压合时间10秒左右。
本发明复合钢塑板及其制造方法，在内侧金属板和塑料芯层上分别开设内侧开孔和塑料开孔，使得减轻了内侧金属板和塑料芯层的重量，尤其是局部去除了塑料芯层的材料，这样就可以达到既保证其强度也可以保留金属材料的塑性功能，增加了金属材料的可塑性成型和应用功能，同步拓宽了复合板塑性甲供区域的应用。
本发明充分利用了钢塑板的自身强度特点，可以作为电视的背板，降低了形成背板的冲压拉伸的成本，同时通过塑料芯层降低金属材料的塑性成型功能，本发明具有如下优点：
第一，在内侧金属板和塑料芯层上分别开设内侧开孔和塑料开孔拓宽了复合钢塑板的可利用空间，实现可打凸包、可抽芽，可卷圆、可折弯、可反折边等结构。
第二，现有刚塑板作为电视的背板使用时，背板的背侧仍然需要增加一个附属结构件来满足一些凸包支撑和牙孔锁附固定作用，本发明复合钢塑板的材料可达到两者结合，达到减少人力物力，从而实现减低制造成本。
第三，外侧金属板的周围区域大于内侧金属板和塑料芯层，使得外侧金属板的周围区域可以单独卷圆、折弯，去掉了中框、面框、里、外侧支撑板，实现五合一的背板技术，大大减少了其电视机的重量，进一步强化了其轻薄的特点。
