对管材端口进行压槽可以满足沟槽式卡箍管材的管道连接要求，目前的压槽一般采用机械轮滚压成型，即由凹轮和凸轮组成轮组直接在管材端口的指定位置进行沟槽成型。
但这样的压槽方式，会导致管材端口外翻呈喇叭口形状，也无法保证加工后管材端部的圆度、直线精度、弧面平整度等几何参数，更无法保障管材两个端口沟槽的平行度保持一致。
为了尽可能降低管材压槽过程对管材结构的负面影响，现有技术大多采用人工方式进行实时监控，并对压槽工艺进行实时调整的方法。但这种方法不仅需要投入大量的成熟工人，导致管材的加工成本上升；同时，由于加工过程中管材发生变形的随机性很强，仅仅依靠人工调整也无法完全避免管材结构的变形。
缺少自动化喇叭口的校形设备及弧面平整工装、局部变形应对方式单一、以及标准化流程的缺失，导致目前行业内依然缺少有效手段能够自动消除管材端口的外翻，而这一问题对于大口径管材的压槽加工则更加明显，这是管材加工行业的公认难题。
公开内容
本公开所要解决的技术问题在于现有技术中的管材压槽工艺容易导致管材变形的技术问题，而提供了一种可以在压槽过程中自动对管材进行校形，使其满足精度要求的加工校形装置及方法。
为解决上述技术问题，本公开第一方面提供一种管材加工校形装置，用于在管材加工时对圆形管材进行自动校形及控形，管材加工校形装置包括：
支撑组件，用于在实施加工时支撑管材，支撑组件包括相互固接的支撑平台和座架，支撑平台设置于管材加工校形装置的底部，座架设置在支撑平台的一端；
加工组件，用于对管材进行加工，加工组件安装于座架上；
校形组件，用于在实施加工时对管材进行校形，校形组件安装于座架上；校形组件包括至少一个下压轮，下压轮与管材的外壁面接触；
动力供给组件，用于向支撑组件、加工组件和校形组件提供动力。
在一种可能的设计中，支撑组件还包括两个支撑轮，支撑轮设置在支撑平台的上方且对称于加工组件设置；管材适于放置在两个支撑轮上并在支撑轮的带动下转动。
这样的设计，直接由支撑轮向管材提供旋转周向力矩，避免额外设置外部旋转力矩供给机构，一方面简化了整体装置，另一方面，可以避免管材在转动过程出现动态参数误差，提升了管材的加工精度。
在一种可能的设计中，校形组件包括至少两个下压轮，两个下压轮分别位于加工组件的两侧。
这样的设计，将两个下压轮分设在加工组件的两侧，当管材管口可能出现变形时，两个下压轮可以从加工组件的两侧分别对管材进行校形，提升了校形效率及校形精度。
在一种可能的设计中，下压轮包括两个A型下压轮，两个A型下压轮对称设置于加工组件的两侧；
A型下压轮包括第一压轮、第一轮架和第一连接机构；
第一压轮与管材的外壁面接触并向管材施加压力，第一压轮的轮轴可转动地设置在第一轮架上，第一轮架通过第一连接机构与座架连接。
在校形时，A型下压轮的第一压轮与管材外壁面为滚动摩擦，相较于滑动摩擦，这样的设计更有助于降低第一压轮和管材的磨损，在提高管材加工精度的同时，提升了第一压轮乃至整个装置的使用寿命。
在一种可能的设计中，第一连接机构包括第一滑动柱、第一动力机构和第一固定架；
第一滑动柱与第一轮架固接，且第一滑动柱适于在第一动力机构带动下沿第一滑动柱的轴线方向往复运动；
第一动力机构通过第一固定架固定连接在座架表面。
通过设置第一滑动柱，可以使第一压轮在不使用时远离管材，避免了不必要的磨损，同时也能使管材更加便于安装，提高了管材的加工效率。
在一种可能的设计中，第一滑动柱的轴线延长线穿过圆形管材横截面的圆心。
这样的设计，使得第一压轮一直沿管材的半径方向移动，这样第一压轮可以向管材表面施加垂直方向的力，提升了第一压轮的压力效果，并降低了了第一压轮以及管材不必要的磨损。
在一种可能的设计中，第一轮架适于通过固定设置在其表面的滑块沿第一滑轨往复运动，第一滑轨固定设置在座架表面。
这样的设计，利用滑块和第一滑轨对第一轮架的移动方向进行进一步限制，进一步限制了第一压轮的位置，提升了校形精度。
在一种可能的设计中，第一连接机构还包括第三固定架，第三固定架的一端固定在座架上，第三固定架远离座架的一端成型有适于第一滑动柱通过并在其中往复运动的孔。
这样的设计，利用固定在座架上的第三固定架对第一滑动柱进行限位，进一步限制了第一压轮的位置，提升了校形精度。
在一种可能的设计中，下压轮的数目为四个，下压轮还包括两个B型下压轮，两个B型下压轮分别设置在两个A型下压轮远离加工组件的一侧，且两个B型下压轮对称设置于加工组件的两侧；
B型下压轮包括第二压轮、第二轮架和第二连接机构；
第二压轮与管材的外壁面接触并向管材施加压力，第二压轮的轮轴可转动地设置在第二轮架上，第二轮架通过第二连接机构与座架连接。
当管材口径较大、管壁较厚且/或槽比较宽的情况下，两个A型下压轮不足以对管材进行完美校形，故通过额外设置的两个B型下压轮，进一步提升装置对于此类管材的校形精度和校形效率。
在一种可能的设计中，第二连接机构包括第二滑动柱、第二动力机构和第二固定架；
第二滑动柱与第二轮架固接，且第二滑动柱适于在第二动力机构带动下沿第二滑动柱的轴线方向往复运动；
第二动力机构通过第二固定架固定连接在座架表面。
与之前的结构效果相似，通过设置第二滑动柱，可以使第二压轮在不使用时远离管材，避免了不必要的磨损，同时也能使管材更加便于安装，提高了管材的加工效率。
在一种可能的设计中，第二滑动柱的轴线延长线穿过圆形管材横截面的圆心。
与之前的结构效果相似，这样的设计，使得第二压轮一直沿管材的半径方向移动，这样第二压轮可以向管材表面施加垂直方向的力，提升了第二压轮的压力效果，并降低了了第二压轮以及管材不必要的磨损。
在一种可能的设计中，第二连接机构还包括滑套，滑套适于通过固定设置在其表面的滑块沿第二滑轨往复运动，第二滑轨固定设置在座架表面；滑 套远离座架的一端成型有适于第二滑动柱通过并在其中往复运动的孔。
与之前的结构效果相似，利用滑块和第二滑轨对滑套、第二滑动柱的移动方向进行进一步限制，进一步限制了第二压轮的位置，提升了校形精度。
在一种可能的设计中，两个A型下压轮远离加工组件的一侧分别设置有内托轮，内托轮适于在管材加工时向管材内表面施加压力；内托轮设置在座架表面，且内托轮适于沿圆形管材的径向往复运动。
当管材口径较大但壁厚较薄的情况下，利用内托轮对管材内壁面进行支撑，可以防止管材发生扭曲变形，进一步提升了装置对于此类管材的校形精度和校形效率。
在一种可能的设计中，内托轮设置在B型下压轮靠近加工组件的一侧。
将内托轮设置在A型下压轮和B型下压轮之间，形成“下、上、下方向”的交错压力，可以防止管材发生不必要的变形，进一步提升了装置对于此类管材的校形精度和校形效率。
在一种可能的设计中，支撑组件、加工组件、校形组件、动力供给组件均受智能控制组件控制。
通过智能控制组件对支撑组件、加工组件、校形组件、动力供给组件进行控制，可以避免人工检测和人工操作，避免了人为误差，提升了管材的加工校形精度。
在一种可能的设计中，智能控制组件包括位置检测机构、处理器和控制机构；处理器接收位置检测机构检测到的各项数值信息，并通过控制机构对动力供给组件进行控制。
这样的设计，将智能控制中的检测功能、判断功能、控制功能集合在一起，进一步提升了管材加工、校形的操作便捷性，同时也提升了管材的加工校形精度。
在一种可能的设计中，加工组件包括向管材外壁面施加压力的下压凸轮和向管材内壁面施加压力的凹轮，下压凸轮与管材的接触点、凹轮与管材的 接触点位于圆形管材的同一条半径上。
这样的设计，通过下压凸轮和凹轮的配合，成型出的凹槽更加精准，提升了管材的加工精度。
在一种可能的设计中，动力供给组件包括动力油缸。
在一种可能的设计中，动力供给组件包括伺服电机。
第二方面，本公开还提供了一种利用如上述管材加工校形装置进行管材加工校形的方法，依次包括如下步骤：
初始状态S0：管材放置在支撑轮上，校形组件以及加工组件均静止于待机位置，支撑轮静止，管材静止；
加工步骤S1：将管材移动至指定位置，支撑轮启动转动并带动管材围绕轴线转动，启动加工组件对管材进行加工；
校形步骤S2：启动校形组件，对管材进行校形；
退出步骤S3：停止校形组件以及加工组件，校形组件以及加工组件脱离管材并回归至待机位置，支撑轮停止转动，管材静止，回复至初始状态S0。
在管材加工时，首先通过加工组件对管材进行加工，之后再对可能出现的喇叭口、弧面变形等情况进行校形，一方面保证了最终成品满足加工要求，同时也保证了校形后的最终成品满足变形精度要求，提升了最终管材成品的加工精度。
上述方法中，加工步骤S1包括：
步骤S11：将管材移动至与加工组件相适配的位置；
步骤S12：启动支撑轮，管材在支撑轮的带动下围绕轴线转动至少两周，检测管材的动态位置参数，使其符合预设要求；
步骤S13：启动加工组件，控制加工组件在管材上形成浅痕迹，确认浅痕迹位置无误；
步骤S14：控制加工组件，在管材上加工指定尺寸的凹槽。
通过对管材的动态位置参数进行检测，可以对待处理的管材圆度、尺寸等进行预判，如果尺寸不符合要求，则可以直接进行退管，避免不规则管材对装置的损坏，也避免消耗不必要的时间。通过形成浅痕迹，可以进一步判断管材所处的位置是否符合要求，并根据判断结果进行相应的位置调整，避免了残次品出现，提升了管材的加工精度，并减低了废品率。
上述方法中，校形步骤S2包括步骤S21，其中步骤S21为：A型下压轮进给，并按照预设参数对管材进行下压。
对于常规管材，通过两个A型下压轮的校形，可以保证校形后的管材精度，避免了喇叭口、弧面平整度不符合要求等情况的出现。
上述方法中，校形步骤S2还包括步骤S22，步骤S22在步骤S21之后，其中步骤S22为：B型下压轮进给，并按照预设参数对管材进行下压。
当管材口径较大、管壁较厚且/或槽比较宽的情况下，两个A型下压轮不足以对管材进行完美校形，故通过额外设置的两个B型下压轮，进一步提升了装置对于此类管材的校形精度和校形效率。
上述方法中，校形步骤S2还包括步骤S23，步骤S23在步骤S22之后，其中步骤S23为：内托轮进给，并按照预设参数对管材进行支撑辅助作业。
当管材口径较大但壁厚较薄的情况下，利用内托轮对管材内壁面进行支撑，可以进一步提升了装置对于此类管材的校形精度和校形效率。
上述方法中，校形步骤S2和退出步骤S3之间还包括验收步骤SX，验收步骤SX为：对管材的沟槽尺寸、管口直径、管口圆度进行检测，以上参数均符合预设误差要求的情况下，进行退出步骤S3。
这样的设计，可以在加工、校形步骤时，实时对加工精度进行检测，如果有部分参数不符合要求，可以及时对管材进行校形加工，避免了残次品再次安装，节约了时间，大大提升了管材的加工校形效率，降低了废品率。
上述方法中，全程利用位置检测机构对管材的位置、尺寸、形状进行检 测，并将检测结果与预存在处理器中的数据标准进行比对，确认上述参数是否符合要求。
通过智能控制组件对支撑组件、加工组件、校形组件、动力供给组件进行控制，可以避免人工检测和人工判断，避免了人为误差，提升了管材的加工校形精度。
本公开的上述技术方案相比现有技术具有以下优点：
本公开通过在加工组件之外设置校形组件，并在加工凹槽后立即进行校形步骤，使得最终的成品管材不会出现喇叭口、椭圆口等情况，弧面平整度、管材圆度高，加工精度非常好。同时利用智能控制组件对加工、校形步骤进行整体控制，避免人工操作所造成的误差，进一步提升了管材的加工精度，降低了废品率，提升了经济效益。

其他实施例
在其他实施例中，所述支撑轮2的数目还可以是三个、四个、六个或多个，全部所述支撑轮2围绕管材外壁面进行设置，所述支撑轮2的数目越多，其对管材的支撑越稳定。另外，所述支撑轮2的数目还可以根据管材长度进行增加，多个所述支撑轮2的转动轴共线，共同对管材进行支撑，这种情况 下，可以根据管材长度或其他需要，将所述支撑轮2的数目设计为四个、五个、六个、七个或其他数值，只要可以起到对管材的支撑效果并带动管材转动，即可实现本公开的设计目的。
在其他实施例中，所述加工组件还可以用于成型凸台或其他环状形状，甚至成型不规则环状形状。只要所述加工组件会对管材施加变形力，本公开的所述管材加工校形装置即可应用，并起到很好的校形效果。此外，所述加工组件也并非一定设置在管材的正上方位置，虽然将所述加工组件设置在管材的周向其他位置会造成力的不均衡，不过在特殊加工要求或特殊环境条件限制时，适当调整所述加工组件的位置，并不影响本公开设计目的的实现。
在其他实施例中，所述下压轮的数目还可以是六个、八个或多个，所述下压轮也可以随意选取所述A型下压轮4或所述B型下压轮5，多个下压轮的位置也可以不强求对称于所述加工组件设置。很明显，所述下压轮的数目越多，整个装置的制造成本越高，但校形效果越好。但所述下压轮数目或选择的区别，与本公开所记载的技术内容和保护范围并无实质区别，仅是使用人员根据自身需求进行的简单选择。
在其他实施例中，所述A型下压轮4中还可以不设置所述第三固定架44，也可以不设置沿所述第一滑轨31往复运动的滑块，这些结构的缺失，会导致所述第一滑动柱43的运动方向出现部分误差。但如果增强所述第一动力机构45和所述第一滑动柱43之间的连接精度，则可以在一定程度上避免上述误差。此外，如果对管材的加工精度要求不高，也可以直接去除所述第三固定架44和滑块。这些调整都不会影响本公开设计目的的实现。
在其他实施例中，所述B型下压轮5中还可以不设置所述滑套54，这样的设置，会导致所述第二滑动柱53的运动方向出现部分误差。但如果增强所述第二动力机构55和所述第二滑动柱53之间的连接精度，则可以在一定程度上避免上述误差。此外，如果对管材的加工精度要求不高，也可以直接去除所述滑套54。这些调整都不会影响本公开设计目的的实现。
在其他实施例中，所述内托轮6的位置还可以设置在所述B型下压轮5 远离所述加工组件的一侧，或是设置四个、六个或多个所述内托轮6，特别是当所述下压轮的数目更多时，所述内托轮6的数目也可以进行适当增加。很明显，所述内托轮6的数目越多，整个装置的制造成本越高，但校形效果越好。
在其他实施例中，所述第一滑动柱43、所述第二滑动柱53和/或所述内托轮6可以并非沿管材半径方向移动，虽然可能造成部分额外磨损，但此项调整并不影响本公开设计目的的实现。
在其他实施例中，所述动力供给组件还可以是伺服电机或其他装置。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本公开的保护范围之中。因此，本公开的保护范围以所附权利要求为准。
