[0020] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments. Embodiment

[0022] Refer to Figures 1-4 , this embodiment provides a numerically controlled four-roll profile bending machine, including an equipment body 1. The equipment body 1 is specifically a numerically controlled four-roll profile bending machine, which is a prior art. A support assembly 2 is arranged on the left side of the equipment body 1. The support assembly 2 includes a rotating seat 201, and the rotating seat 201 is rotatably connected to the left side of the equipment body 1. A swing frame 202 is fixedly connected above the rotating seat 201. The swing frame 202 is L-shaped. A clamping assembly 3 is arranged below the swing frame 202. The clamping assembly 3 includes a support plate 301. Two first electric push rods 302 are fixedly connected to the left and right sides of the support plate 301. One end of the two first electric push rods 302 away from the support plate 301 is fixedly connected with a clamping piece 303. The clamping piece 303 is L-shaped. A limiting rod 304 is fixedly connected to the opposite side of the two clamping pieces 303. A limiting sleeve 305 is movably sleeved on the outer surface of the two limiting rods 304. The limiting sleeve 305 is fixedly connected to the front of the support plate 301. A fixing assembly 4 is arranged above the support plate 301. The fixing assembly 4 includes a support frame 401. The support frame 401 is doorframe-shaped. The support frame 401 is fixedly connected above the support plate 301. A second electric push rod 402 is fixedly connected to the top of the inner surface of the support frame 401. The lower end of the second electric push rod 402 is fixedly connected with a pressing plate 403. The second electric push rod 402 movably penetrates through the upper part of the support plate 301. There is a through hole on the upper part of the support plate 301. The output end of the second electric push rod 402 can pass through the through hole on the support plate 301 to push the pressing plate 403 downward.

[0023] When the above-mentioned device is in specific use, first, the device body 1 is used to bend the profile. After the profile is bent, a cylindrical shape will be formed above the device body 1. At this time, the support plate 301 is lowered to contact the profile, and then the two first electric push rods 302 are used to pull the clamping pieces 303 to clamp both sides of the profile. When the clamping pieces 303 move, the limiting rods 304 will slide in the limiting sleeves 305 for support to prevent the weight of the profile from damaging the first electric push rods 302. After the clamping pieces 303 clamp both sides of the profile, the second electric push rod 402 is started to push the pressing plate 403 downward. At this time, the pressing plate 403 will press down the profile so that it fits against the inner surface bottom of the clamping pieces 303, facilitating the stable fixation of the profile, and thus facilitating the unloading of the profile from the device body 1. Embodiment

[0024] See Figures 1-4 , on the basis of Embodiment 1, the support assembly 2 further includes a counterweight 203. The counterweight 203 is fixedly connected to the lower part of the rotating seat 201. The outer surface of the rotating seat 201 is provided with a limiting assembly 5. The limiting assembly 5 includes an annular tooth 501. The annular tooth 501 is fixedly connected to the outer surface of the rotating seat 201. Above the annular tooth 501, there is a clamping strip 502 engaged. The clamping strip 502 is provided with a protrusion for being clamped between two teeth of the annular tooth 501. The clamping strip 502 is rotatably connected to the left side of the device body 1. An electric winch 6 is fixedly installed above the swing frame 202. The electric winch 6 can remotely control the winding and unwinding of the rope. The electric winch 6 is connected to the support plate 301 by a rope. Above the swing frame 202, there is a through and fixedly connected receiving sleeve 7, and the rope passes through the receiving sleeve 7.

[0025] When the above-mentioned device is in specific use, after the clamping pieces 303 clamp the profile, the electric winch 6 winds the rope to raise the support plate 301, thereby driving the clamping pieces 303 to unload the profile from the uppermost roller of the device body 1. At this time, the clamping strip 502 is lifted upward to cancel the fixation of the annular tooth 501, and then the rotating seat 201 is rotated to turn the swing frame 202 backward, thereby driving the rope and the support plate 301 to place the clamped profile on the ground. When the rotating seat 201 rotates, the counterweight 203 will balance the weight of the swing frame 202 and the structures above it as well as the profile, facilitating safe and labor-saving operation for the user.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
