[0050] Embodiment 2:

[0051] See also Figure 1-9This embodiment provides a technical solution based on the first embodiment: the transmission assembly 10 includes a central shaft 27, a guide shaft B28, a transmission bevel gear 29, a matching bevel gear 30, an eccentric plate B31, a linkage plate B32 and a hydraulic cylinder 33. The inner side of the support seat 3 is vertically rotatably connected with the central shaft 27. The middle parts of the two displacement frames 5 are rotatably connected with the guide shaft B28. The outer sides of the two guide shafts B28 are fixedly connected with the transmission bevel gear 29, and the two transmission bevel gears 29 are symmetrically arranged. The end of the support shaft 6 close to the transmission bevel gear 29 is fixedly connected with the matching bevel gear 30, and the matching bevel gear 30 is also meshed with the corresponding transmission bevel gear 29. The top of the central shaft 27 is fixedly connected with the matching bevel gear 30, and the matching bevel gear 30 is far away from the central shaft 27. One end of the support seat 3 is rotatably connected with a linkage plate B32, the top of the support seat 3 is fixedly connected with a hydraulic cylinder 33, and the output end of the hydraulic cylinder 33 is also rotatably connected with the end of the linkage plate B32 away from the eccentric plate B31, the inner side of the support seat 3 is vertically rotatably connected with an adjusting shaft rod 34, the top and bottom ends of the outer side of the adjusting shaft rod 34 are provided with threaded sections 35, the thread rotation directions of the two threaded sections 35 are opposite, and the two displacement frames 5 are respectively threadedly connected to the outer sides of the two threaded sections 35, the middle part of the adjusting shaft rod 34 is fixedly connected with a synchronous wheel A36, the middle part of one side of the support seat 3 is fixedly connected with an extension frame 37, the top of the extension frame 37 is fixedly connected with a transmission motor 38, and the output end of the transmission motor 38 is fixedly connected with a synchronous wheel B39, and the synchronous wheel B39 and the synchronous wheel A36 are connected by a linkage belt 40;

[0052] Furthermore, a guide bar is fixedly connected to the outer side of the central shaft 27, and the guide shaft B28 is a hollow structure. Both ends of the inner wall of the guide shaft B28 are provided with assembly grooves, and the guide bar is also slidably connected to the inside of the assembly groove. By using the arrangement of the guide bar and the assembly groove, the guide shaft B28 can be vertically displaced along the central shaft 27. When the central shaft 27 rotates, the guide bar is still connected to the inside of the assembly groove, so that the guide shaft B28 can rotate with the central shaft 27.

[0053] In detail, the top of the support seat 3 is fixedly connected with an assembly ear, and the hydraulic cylinder 33 is connected to the top of the assembly ear by bolts. The arrangement of the assembly ear can effectively support the hydraulic cylinder 33 and ensure the stability of the transmission of the hydraulic cylinder 33.

[0054] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] Working principle: first, the extrusion disk 8 of the corresponding arc is sleeved on the outer side of the supporting shaft 6, and the transmission screw 24 is rotated. In conjunction with the connection between the transmission screw 24 and the stabilizing plate 25, the anti-rotation rod 26 can be driven to move vertically through the stabilizing plate 25 until the anti-rotation rod 26 is separated from the transmission ring 18. Then, the transmission disk 19 is rotated to make the transmission disk 19 rotate under the support of the transmission ring 18. In conjunction with the setting of the arc-shaped through groove 20, when the transmission disk 19 rotates, it can push the guide shaft A22, prompting the guide shaft A22 to drive the quick-install shaft 21 to move out of the supporting shaft 6 and snap into the inside of the loading slot 17, thereby forming a quick assembly of the extrusion disk 8. After assembly, the transmission screw 24 is rotated again to prompt the anti-rotation rod 26 to snap into the transmission ring 18, thereby forming a rotation lock of the transmission ring 18.

[0056] Then, the raw material of the frame beam is inserted between the corresponding two extrusion plates 8, and the corresponding hydraulic cylinder 33 is started at the same time to pull the eccentric plate B31 through the linkage plate B32. Since the eccentric plate B31 is supported by the central shaft 27, it can drive the central shaft 27 to rotate. Under the connection between the central shaft 27 and the guide shaft B28, the guide shaft B28 can rotate with the central shaft 27 to drive the transmission bevel gear 29 to shift the matching bevel gear 30, and then the extrusion plate 8 can be driven to rotate through the support shaft 6. The two extrusion plates 8 on the same central shaft 27 rotate in opposite directions, so that the raw material of the frame beam is extruded and formed between the arc groove 9 between the two extrusion plates 8.

[0057] The transmission motor 38 can be started to drive the synchronous wheel B39 to rotate, and the power of the synchronous wheel B39 is transmitted through the linkage belt 40, so as to cause the adjustment shaft 34 to rotate. With the arrangement of the thread segments 35 of the two thread rotation directions, the two displacement racks 5 can be driven to move simultaneously, and the displacement directions are opposite, so as to control the distance between the two extrusion disks 8;

[0058] And according to the processing requirements of the drawings, the corresponding hydraulic rod 15 can be started to pull the linkage seat 16 to move. Since the linkage seat 16 is also connected to the inside of the transmission groove A13, during the displacement of the linkage seat 16, the eccentric plate A12 can be driven to rotate accordingly. And since the linkage plate A14 is also connected between the eccentric plate A12 and the displacement slide 2, during the rotation of the eccentric plate A12, the displacement slide 2 can be pulled by the linkage plate A14. Since the material is located between the two extrusion disks 8, when the displacement slide 2 is vertically displaced, the material can be driven to undergo corresponding bending.
