随着国内经济建设，特别是在建筑行业的发展，方管和矩形管的广泛使用也增加，其增加的使用，它的性能也提出了严格的要求。现在的主要生产厂家，通常有两种方式，一般管工艺成型的标准是弯曲的，方管，又是什么呢？矩管的成型通常称为弯曲，这种弯曲的方法，然而，在方钢管行业将归类为真正的弯曲，另一种是空的弯曲。

With the development of domestic economic construction, especially in the construction industry, the wide use of square and rectangular pipes has also increased. With the increasing use of square and rectangular pipes, their performance has also put forward strict requirements. At present, the main manufacturers usually have two ways. The standard of tube forming is bending. What is square tube? Forming of rectangular pipes is usually called bending, which is a method of bending. However, in square steel pipe industry, it will be classified as true bending and empty bending. 其实，不用说，大家都知道，其实弯曲的过程中，方管矩压缩产生弯曲变形的现象，而内部和外部的方形和矩形管，双向真正的压力状态辊的内壁但是，必须根据专业人士，真正的弯曲的主要优点是相对较小的反弹，并在成形时，是非常准确的，在其辊型的数据，一般内角成型和更准确的准确。然而，这两种方法有一个缺点，就是矩形管弯曲出现在真实的，有可以伸缩，减少出现一般拉伸长度和厚度。然而，空弯的过程中，是弯曲矩形管压缩的行，并产生后的弯折线将被拉长的长度，和空弯产生增稠效果。这种方法的优点是，无论内角小于R弯曲，永远不会产生壁破损，缺点是，由于在同一时间从向上和向下的压力，成型力将超过负载，和将影响管长方使用。但是，在实际使用中尽可能的时候，尽量安排，并在施工过程中选择合适的地点和正确的操作。

In fact, it goes without saying that in the process of bending, square tube moment compression produces bending deformation, while inside and outside square and rectangular tube, the inner wall of two-way real pressure state roll, but according to professionals, the main advantage of true bending is relatively small rebound, and when forming, it is very accurate, in its roll shape data. Generally, the inner angle is formed more accurately and accurately. However, one disadvantage of these two methods is that the bending of rectangular tubes occurs in reality, and can be stretched to reduce the appearance of general stretching length and thickness. However, in the process of empty bending, it is the compressed line of the bending rectangular pipe, and the resulting bending line will be lengthened, and the empty bending will produce thickening effect. The advantage of this method is that no matter the inner angle is less than R bending, the wall will never be damaged. The disadvantage is that because of the pressure from up to down at the same time, the forming force will exceed the load and will affect the rectangular use of the tube. However, in the actual use as far as possible, try to arrange, and in the construction process to choose the appropriate location and correct operation.
