Referring to fig. 1 to 5, a first aspect of the present invention provides a bending apparatus, which includes a bending member 300 and a first guiding member 100. Wherein, bending piece 300 is provided with kink 310, and kink 310 includes an arc surface at least, and the pvc spool can move in order to buckle to certain angle along the arc surface. First guide 100 is fixed connection in bending piece 300, and first guide 100 is provided with first passageway 110, and the pvc spool can move to meeting with the arc surface relatively first passageway 110. The bending member 300 may be made of a steel pipe with a larger diameter, such as a DN150 seamless steel pipe, and the first guide member 100 may be a DN25 seamless steel pipe. In the use process, firstly, the pvc conduit is penetrated, then one side of the pvc conduit is moved, meanwhile, pressure towards the arc surface is applied to the pvc conduit, the pvc conduit is moved along the arc surface to be bent, and the bending speed of the pvc conduit is slow, so that the pvc conduit can be prevented from being broken, and the smoothness of the inner wall of the pvc conduit can be maintained. Meanwhile, the bending angle of the pvc can be adjusted according to actual needs, and one-time bending forming of the pvc line pipe can be completed.
