[0002] Metal materials refer to materials with properties such as luster, ductility, easy conductivity and heat transfer. They are generally divided into two types: ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc. Among them, steel is the basic structural material, known as the "skeleton of industry". Due to the progress of science and technology, the widespread application of various new chemical materials and new non-metallic materials has led to an increasing number of substitutes for steel, and the demand for steel has decreased relatively.

Most of the current metal materials can only be bent at conventional angles during processing. It is not convenient to bend metal plates or sheets into a truncated cone or cylindrical shape. Therefore, it is necessary to propose a bending machine for metal material manufacturing to solve the above problems. Utility Model Content

[0025] Embodiment

[0026] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a bending machine for manufacturing metal materials, including a support structure 100 and a bending structure 200.

[0027] Please refer to Figures 1 - 4 , the support structure 100 includes a fixing frame 110, a support member 120 and two support rollers 130. The support member 120 is fixed to the bottom of the fixing frame 110, and the two support rollers 130 are rotatably connected to both sides of the fixing frame 110.

[0028] The support member 120 includes a support column 121. The support columns 121 are symmetrically fixed to the bottom of the fixing frame 110. A connecting plate 122 is fixed between the support columns 121, and a support pad 123 is fixed to the bottom of the support column 121. Here, the support member 120 is used to support the fixing frame 110.

[0029] Please refer to Figures 1 - 6The bending structure 200 includes a first threaded rod 210, a second threaded rod 220, a driving unit 240, an adjusting member 250 and a bending roller 260. The first threaded rod 210 and the second threaded rod 220 rotate and penetrate the fixed frame 110. The first threaded rod 210 and the second threaded rod 220 are connected to each other through a transmission unit 230. The first threaded rod 210 is threadedly connected to a first movable frame 211, and the second threaded rod 220 is threadedly connected to a second movable frame 221. The driving unit 240 is installed on the first movable frame 211, the adjusting member 250 is installed on the second movable frame 221, and the bending roller 260 is installed between the driving unit 240 and the adjusting member 250. Here, the first movable frame 211 and the second movable frame 221 are both slidably connected to the inner surface of the fixed frame 110.

[0030] The first movable frame 211 has a threaded hole inside that matches the first threaded rod 210, and the second movable frame 221 has a threaded hole inside that matches the second threaded rod 220. The bottom of the second threaded rod 220 is keyed with a hand wheel 222, and the threaded hole here can facilitate the first movable frame 211 and the second movable frame 221 to move back and forth up and down. The transmission part 230 includes two transmission wheels 231, and the two transmission wheels 231 are keyed to the first threaded rod 210 and the second threaded rod 220, respectively. The two transmission wheels 231 are connected by a transmission chain 232. This can drive the first threaded rod 210 and the second threaded rod 220 to rotate at the same time through the setting of the transmission part 230, so as to facilitate height adjustment and form different bending arcs.

[0031] The driving part 240 includes a servo motor 241 and a connecting frame 242. The servo motor 241 is installed on one side of the connecting frame 242. The connecting frame 242 is rotatably connected to the first movable frame 211. Here, the servo motor 241 can drive the bending roller 260 to rotate, so as to perform circular bending operation on the metal plate. The adjusting part 250 includes a threaded tube 251 and a fixed block 253. One end of the threaded tube 251 is fixed with a bearing 252. The fixed block 253 is rotatably connected to the second movable frame 221 through a connecting column 2532. A threaded column 254 is rotatably penetrated through the inside of the fixed block 253. The threaded column 254 is threadedly connected to the inside of the threaded tube 251. Here, the threaded column 254 makes the threaded tube 251 extend downward and drives one end of the bending roller 260 to move downward. Such adjustment can make the metal plate bend into a frustum shape. Both ends of the bending roller 260 are respectively fixed with a first pin 261 and a second pin 262. The first pin 261 rotatably penetrates through the connecting frame 242 and is connected to the end of the output shaft of the servo motor 241. The second pin 262 is interference-fitted inside the bearing 252. Here, the bending roller 260 is used to perform bending operation on the metal plate. The fixing frame 110 is provided with notches 111 matching the first pin 261 and the second pin 262. The other end of the threaded column 254 is key-connected with a knob 2531. Here, the first pin 261 and the second pin 262 pass through the notches 111.

[0032] Specifically, the working principle of the bending machine for manufacturing metal materials: When in use, according to the bending arc requirement of the metal plate, the second threaded rod 220 is rotated by the handwheel 222. In this way, under the action of the transmission part 230, the first threaded rod 210 can be driven to rotate at the same time. In this way, the first movable frame 211 and the second movable frame 221 can move up or down at the same time, and drive the bending roller 260 to lift and lower at the same time. At this time, the metal plate is placed between the bending roller 260 and the supporting roller 130. Then, the servo motor 241 is used to drive the bending roller 260 to rotate to complete the bending operation on the metal plate. In this way, it can be bent into a circular arc shape or a cylindrical shape. It can also rotate the threaded column 254 by the knob 2531. In this way, the threaded tube 251 will drive one end of the bending roller 260 to move downward, so that one end of the bending roller 260 is inclined downward. When it is inclined to a suitable position, the plate is placed between the supporting roller 130 and the bending roller 260. Then, the servo motor 241 is used to drive the bending roller 260 to rotate again, and it can be bent into a frustum shape or an arc-shaped plate inclined to one side. In this way, it is convenient to adjust the bending arc during the bending process, which is beneficial to meet different bending arc bending requirements. At the same time, it can be bent into an uncommon frustum shape for more convenient use.

[0033] It should be noted that the specific model and specification of the servo motor 241 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0034] The power supply and principle of the servo motor 241 are clear to those skilled in the art and will not be described in detail herein.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
