[0003] 在现有技术中,为了保证对具体加热炉形状的要求以及满足对具体加热热量分别的要求,通常需要对炉管的形状进行具体形状的弯曲。 [0003] In the prior art, in order to ensure that the specific requirements of the furnace and the shapes meet the specific heat of the heating requirements are often necessary for bending furnace tube shape specific shape. 对于加热炉炉管的弯曲,在现有技术中往往采用冲压成型的方式。 For the heating furnace tube is curved, often used in the prior art stamping process. 这种成型方式可以高效快速地实现弯曲加工,并且加工精度高,成本较低,在现有技术中具有广泛应用。 This forming method can be implemented quickly and efficiently bending, and high precision, low cost, has a wide application in the prior art. 但是,这种加热方式容易在加热炉炉管的纵向方向上产生显著大量的不均匀变形,导致加热炉炉管的横截面面积在炉管的纵向方向上具有较大变动,这使得在加热过程中加热均匀性难以控制,而且,容易在使用的过程中产生不均匀的应力集中,从而导致加热炉的使用稳定性、安全性大大降低,而且缩短了加热炉的使用寿命。 However, this heating easy to produce significant quantities of inhomogeneous deformation, resulting in the cross-sectional area of ​​the heating furnace tube has a large variation in the longitudinal direction of the tube in the longitudinal direction of the heating furnace tube, which makes the heating process heating uniformity is difficult to control and prone to non-uniform stress concentrations during use, resulting in the use of a heating furnace stability, safety is greatly reduced, and shorten the life of the furnace.

[0004] 在现有技术中也具有使用弯折滚对工件进行弯折的方案。 [0004] Also with the use of roll bending on the workpiece is bent in the prior art solutions. 但是,这种方案往往对工件采用逐个弯的弯曲,由于工件的纵向尺寸较大,在工件的完整转动过程中,这种加工往往需要较大的加工空间,而且,由于加工过程为采用逐个弯的方式,加工过程较长,加工效率较低,由此导致加工成本上升,而且难以保证加工的形状精度。 However, this scheme often employed to bend a workpiece bent one by one, due to the large longitudinal dimension of the workpiece, in the course of a complete rotation of the workpiece, such processing often requires a large working space, and, one by one due to the bending process is employed manner, the process is longer, lower processing efficiency, thereby resulting in increased processing costs, and it is difficult to ensure the shape accuracy machining.
