图2为本申请实施例提供的金属产品整形方法的流程图。根据不同的需求，该流程图中步骤的顺序可以改变，某些步骤可以省略。该金属产品整形方法包括：
S1、获取工件的位置数据信息，所述位置数据信息由测量系统30测量工件获得。
其中，工件的位置数据信息为工件表面各个目标位置点与测量系统30之间的高度值。具体地，该将工件固定放置于预设位置上，移动测量系统30至工件的上方，测量系统30沿预设平面移动以对工件表面进行测量，以获取工件的位置数据信息。例如，工件表面上的目标位置点A，则测量系统30对目标位置点A的位置进行测 量，以获得目标位置点A与测量系统30之间的高度值。本实施例中，测量系统30为激光镭射系统。
本实施方式中，测量系统30通信连接于处理器10，处理器10通过串行通信协议直接调取测量系统30测量工件的位置数据信息。具体地，串行通讯协议为Modbus/TCP协议。可以理解，测量系统30也可将测量得到的位置数据信息实时发送至处理器10。
在一些实施例中，步骤S1包括：建立所述测量系统30的坐标系，并将所述坐标系与所述工件的位置数据进行绑定；移动所述测量系统30依次量取所述工件表面的多个目标坐标点的位置数据信息。
其中，坐标系为三维坐标系。具体地，将坐标系与工件的位置数据进行绑定，以建立工件的位置点在该坐标系中对应的坐标值之间的一一对应。
具体地，测量系统30沿预设运动轨迹移动对工件表面上各个目标坐标点的对应的位置测量以获取各个目标坐标点的位置数据信息。
其中，预设运动轨迹可为沿工件的长度方向进行移动的轨迹。
S2、将所述位置数据信息转换成坐标信息，并对所述坐标信息进行拟合得到所述工件的表面轮廓曲线。
其中，处理器10中建立预设坐标系，并将预设坐标系与工件的位置数据进行绑定，以使工件的不同位置点的位置在该预设坐标系中一一对应的坐标点，建立位置点与坐标点之间的对应关系，基于该对应关系，通过已知的工件不同位置点的位置数据信息得到各位置点对应的坐标信息。其中，坐标信息为工件各个位置点对应的坐标值。示例性的，工件表面的位置点A的位置数据为位置点A与测量系统30之间的高度值Ha，基于工件的位置点与坐标系中的对应的坐标值之间的一一对应，则该位置点A在坐标系中对应有唯一的坐标值(Xa、Ya、Za)。
本实施例中的拟合方式为利用工件表面多个位置点对应的坐标值，采用最小二乘法拟合出工件表面的轮廓曲线。
本实施例中，拟合能够将多个离散的位置点坐标值使用一条曲线连接起来，以图形化展示工件表面的轮廓，以将工件表面轮廓展 现的更加清晰直观。
在一些实施例中，步骤S2包括：建立测量坐标系，并将所述测量坐标系与所述工件的位置数据绑定；基于所述测量坐标系与所述工件的位置数据绑定，将所述位置数据信息转换成坐标信息；对所述坐标信息进行拟合得到所述工件表面轮廓曲线。
其中，测量坐标系设于处理器10中，将测量坐标系与工件的位置数据绑定，以建立工件表面上的位置点与测量坐标系中对应的坐标值之间对应关系，以使工件表面上的位置点与测量坐标系中对应的坐标值之间一一对应。基于该对应关系，通过已知的工件不同位置点的位置数据信息对应得到各位置点对应的坐标信息。其中，坐标信息为工件各个位置点对应的坐标值。利用最小二乘法对坐标信息进行拟合得到工件的表面轮廓曲线，以通过测量计算的手段获得工件表面的轮廓曲线，以便于分析工件的变形情况，以实现工件的变形情况可视化。其中，表面轮廓曲线为工件表面的轮廓线。
在一些实施例中，所述对所述坐标信息进行拟合得到所述工件表面轮廓曲线包括：基于所述坐标信息一一对应得出各个位置点的坐标值(X、Y、Z)；根据多点最小二乘法，计算出理想平面方程Z＝AX+BY+C，得出各个位置点平面度偏差值；基于计算得到的各个位置点的平面度偏差值，拟合出所述工件的表面轮廓曲线。
示例性的，假设位置点的数量为9个(N＝9)，则9个位置点的坐标值分别为(Xi、Yi、Zi)，(i＝1、2、3，、、、，9)。
根据多点最小二乘法，设目标函数为：
Figure PCTCN2021122389-appb-000001
Figure PCTCN2021122389-appb-000002
根据极值原理，欲使F(A、B、C)为最小值，必有
Figure PCTCN2021122389-appb-000003
即：
Figure PCTCN2021122389-appb-000004
在已知(Xi、Yi、Zi)的条件下，依据上述公式可求得各个位置点对应的平面参数A、B、C。
其中，平面度偏差值为工件实际表面与工件理想平面进行比较，两者之间的距离。表面轮廓曲线为实际工件表面上的表面轮廓线。
具体地，基于获取的各个位置点的平面参数A、B、C，拟合得到工件的表面轮廓曲线，以实现工件的变形情况可视化。
其中，拟合是将工件表面上多个离散的目标位置点用一条光滑的曲线连接起来，以图形化展示工件表面的轮廓，以将工件表面轮廓展现的更加清晰直观。
S3、将所述表面轮廓曲线与标准轮廓曲线进行对比，生成对比结果；
其中，表面轮廓曲线与标准轮廓曲线进行对比，以获得各个位置点对应的变形量，将各个位置点的变形量判断是否在预设范围内，生成判断结果，基于判断结果得到对比结果。其中对比结果工件的表面轮廓曲线上的位置点与该位置点对应的标准工件的标准轮廓曲线的位置点之间的变形量。
本实施例中，变形量为工件的表面轮廓曲线上的位置点与该位置点对应的标准工件的标准轮廓曲线的位置点之间的距离。例如，工件的表面轮廓曲线上的位置点A与该位置点A对应的标准工件的标准轮廓曲线的位置点A’的距离为0.2mm，则对比后工件位置点A的变形量即为0.2mm。预设范围为预先设定的合格限值，例如0.25mm，即，变形量在0.25mm以内，则工件合格，无需进行整形，否则，则工件为不合格。
在一些实施例中，步骤S3包括：将所述表面轮廓曲线与标准 轮廓曲线进行对比以获取各个位置点对应的变形量；判断各个位置点的变形量是否在预设范围内，生成判断结果；基于所述判断结果生成所述对比结果。
具体地，标准轮廓曲线为标准工件的轮廓曲线，通过将工件的表面轮廓曲线与标准工件的标准轮廓曲线进行对比，以获取工件上各个位置点对应的变形量。
可以理解，工件与标准工件属于同一类产品，工件的位置点与标准工件的位置点具有一一对应关系。
其中，预设范围为判定工件是否合格的依据。例如，预设范围为0.25mm。基于上述设定，若工件表面位置点A的变形量为超过0.25mm，则A点变形量超出预设范围。
进一步地，所述判断各个位置点的变形量是否在预设范围内，生成判断结果包括：若各个位置点的变形量均在所述预设范围内，则判定所述工件为合格品；若各个位置点的变形量至少一个不在所述预设范围内，则判定所述工件为不合格品。
图3-图12是本申请实施例提供的工件表面十种变形种类的曲线图。其中，工件位于一三维坐标系下，该三维坐标系与工件的位置数据绑定，且与测量系统30的坐标系统一。测量系统30对工件表面各个预设点的位置进行测量，获取各个预设点的位置数据信息，基于获取的各个预设点的位置数据信息转换为各个预设点在该三维坐标系下的坐标信息，例如，预设点A的坐标信息为(Xa、Ya、Za)。通过将工件放置在预设位置上，进而可根据各个预设点的坐标信息判断工件的变形情况。可以理解地，上述工件的变形示例仅代表工件变形种类的一部分，工件变形可根据各个预设点的变形情况通过不同的排列组合进行界定。
示例性的，工件放置的预设位置所在的平面与三维坐标系下X/Y所在的平面平行，此时，通过判断工件各个预设点的坐标信息的Z轴坐标值判断工件在各个预设点的变形情况，例如，可接收的变形量设定范围为(±0.25mm)，若预设点A的Z轴坐标为0.3mm，则预设点A超出可接收变形量的0.25，判定预设点A的变形为上凸；若预设点B的Z轴坐标为-0.3mm，则预设点B超出可接收变形量的 -0.25mm，判定预设点B的变形为下凹。
图13是本申请实施例提供的工件表面变形量判定的示意图。其中，表面轮廓曲线0为工件的标准轮廓线，表面轮廓曲线1为整形前工件的表面轮廓线，表面轮廓曲线2为整形后工件的表面轮廓线。可以理解地，将工件表面轮廓线与标准轮廓线进行对比，各目标位置点的变形量均在标准轮廓线的(±0.25mm)以内为合格品。示例性的，若工件表面位置点A的变形量为0.1mm，A点变形量未超出预设范围(±0.25mm)，则判定该工件为合格品，则无需对A点进行整形；若工件表面位置点A的变形量为0.3mm，A点变形量超出预设范围(±0.25mm)，则判定该工件为不合格品，需要对A点进行整形。
具体地，通过各个位置点的变形量与预设范围对比，以实现获得各个位置点的变形量是否在预设范围内的结果，基于判断结果得到对比结果，以获得工件表面上不同位置点的变形情况。例如，工件表面的目标位置点为9个，则分别将9个目标位置点对应的变形量分别与预设范围对比，以获得9个位置点上的变形量是否在预设范围内。
S4、根据所述对比结果，得到所述工件的整形信息。
具体地，整形信息包括整形方式、整形量和保压时间，以对不同工件的变形情况匹配相对应的整形方式、整形量和保压时间，以实现对各个工件的精确整形。
示例性的，工件上目标位置点有9个，其中4个位置点上的变形量超出预设范围，则基于该4个位置点上的变形量在预设整形信息集中匹配最佳的整形方式、整形量和保压时间。
可以理解，保压时间是对工件整形后的压力保持时间，以消除工件整形后的应力，提高工件整形效果。
S5、基于所述整形信息，控制整形系统40对所述工件进行整形。

本实施例中，驱动件431为伺服器；传动件432为丝杆。
在一些实施例中，步骤S5包括：基于所述整形信息生成整形指令，并将所述整形指令发送至整形系统40；整形系统40中的整形组件43依据所述整形指令开始工作，以依次对所述工件的各个位置点进行整形。
本实施例中，整形系统40还包括控制器(未图示)，具体地，处理器10基于Modbus/TCP通信连接于控制器，以将整形信息发送至控制器。控制器基于获取的整形信息自动生成整形指令。其中，控制器为PLC控制器。控制器基于CANlink协议通信连接于整形系统40，控制器将整形指令发送至整形系统40，整形系统40基于整形指令依次对工件的各个位置点进行整形，以对工件自动整形，降低人力人本投入，提高工件整形效率。
S6、判定所述工件的整形效果，整形合格则输出第一信号，整形不合格则输出第二信号；
其中，对工件进行一次整形后，测量系统30重新获取整形后工件表面的位置数据信息，并基于整形后的位置数据信息转换为整形后的工件表面坐标信息，以对整形后的工件表面坐标信息进行拟合，以得到整形后的工件的表面轮廓曲线，并将该表面轮廓曲线与标准工件的标准轮廓曲线进行对比，以判定整形后工件的整形效果，整形合格则输出第一信号，整形不合格则输出第二信号。
S7、基于所述第一信号发出第一命令信号，根据所述第一命令信号将所述整形系统40回归至初始位置。
基于第一信号获知整形后的工件判定合格，处理器10发送第一 命令信号，以将整形系统40回归至初始位置，以对下一个工件进行整形。
S8、基于所述第二信号发出第二命令信号，根据所述第二命令信号控制所述整形系统40，并对所述工件进行下一次整形。
基于第二信号获知整形后的工件判定不合格，处理器10发送第二命令信号，以对该工件进行下一次整形。
