DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the utility model.

[0019] As Figs. 1 to 2As shown, the embodiment provides a numerical control pipe bender, which comprises a first swing frame 1, a center frame 2, a base frame 3, a second swing frame 4, and a motor 5. The top end of the base frame 3 is welded with the center frame 2. The two sides of the center frame 2 are respectively hingedly connected with the first swing frame 1 and the second swing frame 4. The first swing frame 1 and the second swing frame 4 change their included angle with the center frame 2 through the first oil cylinder 6 and the second oil cylinder 7 respectively. The first swing frame 1 and the second swing frame 4 are provided with rollers 8. The center frame 2 is provided with a conveying roller shaft 9. The motor 5 is drivingly connected with the conveying roller shaft 9. The first swing frame 1 and the second swing frame 4 are provided with an adjusting groove 71. The rollers 8 on the swing frames are installed on bearings 73 of bearing frames 72. In order to flexibly adjust the rollers 8, the bottom ends of the two bearing frames 72 are installed on the swing frames through a base plate 74. The relative positions of the rollers 8 on the swing frames are indirectly locked by penetrating the adjusting groove 71 from the back of the swing frame through the cooperation of screws and gaskets, and then being screwed into the connecting holes on the base plate 74.

[0020] Further, the side end of the center frame 2 is provided with a side frame 10. The side frame 10 is provided with a transmission box 11. The transmission box 11 comprises an input end and an output end. The output end is connected with a transmission roller shaft and rotates synchronously. The transmission box 11 is usually driven by two bevel gears. The input end and the output end, which are at a ninety-degree included angle, can be drivingly matched.
