DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-2 In an embodiment of the present invention, a spiral multi-blade forming machine includes a shaping rolling assembly 1, a positioning chuck 2, a forming frame 3, a rotating device 4, a support frame 5, and a base 6 connected in sequence from top to bottom. The upper end of the forming frame 3 is fixedly connected to the positioning chuck 2, and the lower end is fixedly connected to the rotating device 4. The rotating device 4 includes an upper rotating seat 41 fixedly connected to the forming frame 3 and a lower rotating seat 42 fixedly connected to the support frame 5. The upper rotating seat 41 is rotatably connected to the lower rotating seat 42. A workbench 7 is provided on the support frame 5. The workbench 7 is provided with a mechanism for driving the upper rotating seat 41 and the lower rotating seat 42 to rotate. The working platform is combined with components such as the rotating device, and cooperates with a foot-operated lifting switch to adjust the lifting speed to form the blades.

[0025] The shaping rolling assembly 1 includes a shaping frame 11 fixedly connected to the claws of the positioning chuck 2. The positioning chuck is a multi-cylinder positioning chuck. In the present embodiment, the positioning chuck 2 is provided with an upper claw, and the shaping frame 11 is provided with three claws. The three claws are evenly arranged on the three claws of the positioning chuck 2. A positioning shaft 12 and a rolling roller shaft are fixedly connected to the inner side of each claw, and a rolling roller 13 is sleeved on the rolling roller shaft.

[0026] The base portion 6 includes a lifting plate 65 that is arranged to slide up and down and a power mechanism that drives the lifting plate 65 to move up and down. The lifting plate 65 is arranged coaxially with the shaping frame 11. A bearing seat 66 is provided at the upper end of the lifting plate 65. A turbine screw lift 63 and a motor 61 for driving the turbine screw lift 63 to rotate are provided in the base portion 6. Two turbine screw lifts 63 are provided and the two turbine screw lifts 63 are arranged in parallel. The two turbine screw lifts 63 are connected by power through a transmission shaft 64. The turbine screw lift 63 is connected to the motor 61 by power through a coupling 62. Both ends of the lifting plate 65 are sleeved on the screw in the turbine screw lift 63, and the lifting plate 65 is threadedly connected to the screw.

[0027] When the present invention is in use, the spiral shaft is first installed on the bearing seat 66 on the lifting plate 65, and then the upper end of the spiral shaft is extended through the support frame 5 and the positioning chuck 2 of the molding frame 3 to the molding rolling assembly 1, and then the claws of the positioning chuck 2 are adjusted to adjust the relative distance between the claws in the molding frame 11 by contraction or separation of the claws. After the adjustment is completed, the blade passes through the positioning shaft and the rolling roller, and the preparation work is completed. After the preparation is completed, the motor 61 is started, and the coupling 62 and the turbine screw lift 63 are driven to rotate by the motor 61. While the turbine screw lift 63 rotates, the lifting plate 65 on the turbine screw lift 63 is driven to move upward, and then the spiral shaft is pushed upward by the lifting plate 65. Due to the upward movement of the spiral shaft, the blade connected to the spiral shaft will be driven to move upward relative to the rolling shaft, and then the rolling forming of the blade can be completed.
