Description

本发明属冶金类,具体说是一种制造轻型金属型材的方法。
本制造法最适于制造各个工业领域,特别是建筑业中广泛应用的梁、柱、横梁,以及其它结构。
采用成型轧材制造轻型金属型材的方法已广为人知。运用这种制造法,须将轧料(槽钢或工字钢)沿纵向曲折地切割成两个构件,然后,将其分开,使曲折边的凸出部位对接,再通过焊接制成轻型型材。按这种方法,可得到热轧钢材的制品。与此同时,应用这种已知方法制造轻型金属型材会形成较多的金属废料。
由于坯料是槽钢、工字钢和Z型材,所以,使用这种方法能加工出的轻型型材的种类有限。
另一已知的轻金属型材制造法是:将卷材铺成板材,加以校正。然后,进行弯曲加工,制成型材,再按规定长度进行切割,并沿折曲线纵向分割成构件。将加工出的构件对拼起来,组成分布着截线的型材,最后焊接成一体。(见扬·勃鲁德卡和其它“轻型钢结构”,1974.<莫斯科>建筑出版社,P.320-325)。
按这种方法,可选用弯曲型材加工轻型金属型材。但是,与前面所述的方法一样,型材的加工种类有限。另外,为保证无废料和沿折曲线纵向分割弯曲型材工序的连续性,须将沿弯曲型材逐件焊成一条线,并在焊接前对型材的两端进行处理。这就需要辅助工艺作业,并增加相应的设备、工具和劳动消耗。
沿折曲线实现纵向分割须在弯曲型材的壁上进行,即纵向分割在板材造型后进行。这将导致被分割构件受弯曲型材内部应力的影响而变形。为防止被分割构件在其折曲边的凸出部完全接合前产生变形,须采用金属用量大的设备(辊床或伴用夹具)。
由于只能沿一条折曲线对弯曲型材的壁进行纵向分割,所以,增加轻型金属型材高度的可能性受到限制。
弯曲型材被分割构件的折曲边的凸出部分,须采用焊条焊接,或在二氧化碳环境下实施半自动焊接。这就需要增加辅助的材料消耗(焊条、焊丝、二氧化碳)。为了达到与已知制造法工艺作业线相应的生产能力,必须备有大量焊机。弯曲型材各构件的残余应力、焊接时产生的变形、制成的轻金属型材未经校准,均会破坏型材的几何形状,即降低型材的质量。
本发明的任务是建立一种制造轻型金属型材的方法,该制造法的作业顺序和完成作业的特点能提高流程的工艺性,使板材的纵向分割变得连续,全自动并且是无废分割,提高轻型金属型材的质量,并增加其种类。
实现本发明任务的方法是:将卷材铺成板材,加以校正,再弯曲加工成型材,按规定长度进行切割,然后,沿折曲线将其纵向分割成构件,并将加工成的构件对拼起来,组成一个分布着截线的型材,最后焊接成一体的轻型金属型材材料制造方法。根据本发明,沿折曲线纵向分割板材应在弯曲处理前进行,并且至少分割成两个构件,然后按规定长度切割每个加工出的构件,再将构件按折曲线凸出边对接成一个平面,组成带截线的带材,并将其焊接成一体。
为得到带孔的分布着截线的带材,须将构件按折曲边凸出部对接起来。
为得到无孔的分布着截线的带材,须将构件的直线边对接起来。
为了得到孔位按方格-蜂巢方式排列的,分布着截线的定长带材,在沿折曲线将板材纵向分割为三个构件时,中间构件的折曲线相互必须对称。另外,还将用中间构件加工成带折曲边的对称角材。
为了得到孔位是棋盘状排列、分布着截线的定长的带材,在沿折曲线将板材纵向分割为三个构件时,中间构件的折曲边相互间必须是对应的。
如用轧辊机使型材成形,在将两个以上构件焊接成分布着截线的带材后,必须打磨焊缝。
以下列举的是根据本发明适应的辊型金属型材制造法的实施例,并配有附图,其中:
图1为采用卷坯板材制造轻型型材的工艺线示意图。
图2为用两个构件构成的、分布着截线的有直线边的带材局部立面图。
图3为带有折曲边的构件的局部立面图。
图4为规定长度、但不限宽度,带有折曲边、分布着截线的带材的局部立面图。
图5为规定长度,但不限宽度的直线边,分布着截线的带材的局部立面图。
图6为沿折曲线将板材纵向分割为三个构件、中间构件各边相互对应的纵向分割局部立面图。
图7为孔位是棋盘状排列、分布着截线的带材的局部立面图。
图8-19为采用本制造法加工的成品实施例。
本轻型金属型材制造法是:将卷材铺成板材,并加以校正。校正后沿折曲线将板材纵向分割成至少两个以上构件。然后,按规定长度切割每个构件,在一个平面上对接起来,组成一个分布着截线的带材,再焊接成一体。得到的分布着截线的带材经过弯曲处理,即可形成弯曲的轻型型材。
当需要得到有孔的轻型金属弯曲型材时,采用将构件折曲边的凸出部对接制成的分布着截线的有孔带材。
如果需要得到无孔的轻型金属弯曲型材,原应将构件沿直线边对接,组成分布着截线的带材。
在按工艺要求得到孔位按方格-蜂巢方式排列、分布着截线的带材时,可按折曲线将板材纵向分割为三个构件。这时,中间构件的折曲边相互对称。
如果将上述折曲边相互对应地配置,则可得到孔位呈棋盘排列、分布着截线的带材。
本轻型金属型材制造法可用众所周知的设备以自动方式实施。
将成卷的板材2装到松卷装置1上(图1)。然后将板材送入校正装置3进行校正。校正后的板材输入纵向分割装置4,沿折曲线进行切割,比如分割成三个构件5、6、7,并且构件6的折曲边相互间对称配置。
然后,在装置8中,如在剪板机上,构件5、6、7按规定长度进行切割。定长度构件5、6、7在分类装置(图中未示出)中退出啮合,组合成各种类型规定长度的分布着截线的带材。
如果将构件5和7(图2)的折曲边的凸出部对接起来,即可加工成直线边的分布着截线的带材9。
折曲边相互对称布置的定长度构件6(图3)进入收集器(图中未标明),随后进入焊机(图中未标明),将其折曲边的凸出部焊接起来组成分布着截线的带材10(图4),带材有折曲边及孔11,孔呈方格-蜂巢方式排列。在这种情况下,分布着截线的带材10可以不受宽度限制。
如果按工艺要求需加工不限宽度的、分布着截线的、有直线边的带材12(图5)时,则应将构件5(图1)和7的折曲边的凸出部焊在分布着截线的带材11上(图4)。
如果将构件6(图6)的折曲边相互间对应地配置,则可以按上述方法加工出孔位14呈棋盘状排列、分布着截线的带材13(图7)。
当全部构件5、6、7焊接完毕后,必要时可以打磨焊缝,如使用刀具打磨(图中未示出)。
然后在型材弯曲机(图中未示出)上加工成轻型金属型材。
由此可见,应用本发明建立的轻型金属型材制造法能保证工艺流程全部实现自动化,形成无废生产,并能够提高用分布着截线的带材加工制成的轻型金属型材的质量,增加型材的种类。如应用本制造法可加工出开口型轻型金属型材-槽钢(图8、9、10)C型材(图11)Z型材(图12、13)角材(14、15)等,以及封闭型轻型金属型材-方形截面,(图16、17)矩形截面(图18)等,还可以加工工字型焊接金属构件(图19)。
