[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 As shown, this embodiment proposes a metal bending mechanism with high material placement accuracy, including a bending machine body 1, a negative pressure fixing component 2 for accurate bending fixing is provided on one side of the bending machine body 1, and electromagnetic fixing components 3 for auxiliary fixing are provided on both sides of the fixing component. like Figure 2 and Figure 3As shown, the negative pressure fixing assembly 2 includes a fixing plate 201 bolted to one side of the bending machine body 1. The top of the fixing plate 201 has several ventilation holes. A placement basket 202 is welded below the fixing plate 201, serving as the main support. A vacuum pump 203 is bolted inside the placement basket 202. A vacuum suction plate 204 is snapped onto the top of the fixing plate 201. Several vacuum suction cups 205 are provided on the top of the vacuum suction plate 204 to provide negative pressure power and for negative pressure adsorption of the plate material. A barometer 206 is provided on one side of the vacuum suction plate 204. The barometer 206 is composed of a large... The data is controlled by the Internet of Things. The fixed plate 201 is connected to the bending machine body 1 by bolts. The placement basket 202 welded below it is equipped with a vacuum pump 203. The vacuum suction plate 204 is snapped onto the top of the fixed plate 201. After the vacuum pump 203 is started, it draws air from the inside of the vacuum suction plate 204 through the air hole of the fixed plate 201 to form a negative pressure, so that multiple vacuum suction cups 205 on the top can adsorb metal plates. The barometer 206 monitors the air pressure in the suction cups in real time and feeds the data back to the control center through the Internet of Things to ensure that the adsorption force is always within the set threshold, thereby accurately fixing the material position.

[0020] like Figure 2 and Figure 3 As shown, the electromagnetic fixing component 3 includes an electromagnet 301 snapped onto the top of the fixing plate 201. A PLC control component 302 is installed inside the placement basket 202. A voltage sensor 303 is installed on one side of the PLC control component 302. The electromagnet 301 is electrically connected to the PLC control component 302 and the voltage sensor 303 respectively. The electromagnet 301 is located on one side of the vacuum suction plate 204. Both the electromagnet 301 and the PLC control component 302 are controlled by the Internet of Things. The electromagnet 301 is snapped onto the fixing plate 201 and adjacent to the vacuum suction plate 204. The PLC control component 302 in the placement basket 202 receives IoT commands and data from the voltage sensor 303 and dynamically adjusts the current intensity of the electromagnet 301. When adsorbing ferromagnetic plates, the electromagnet 301 is energized to generate an auxiliary magnetic attraction force, which works in conjunction with the vacuum suction cup 205 to further enhance the positioning stability of the plates and prevent micro-displacement during bending.

[0021] like Figure 5 As shown, a fixing bolt 4 is threadedly connected to the top of the fixing plate 201, and an auxiliary plate 5 is threadedly connected to the top of the fixing bolt 4. A soft rubber pad 6 is glued to the bottom of the auxiliary plate 5. The soft rubber pad 6 is located at the top of the fixing plate 201. The fixing bolt 4 penetrates the auxiliary plate 5 vertically and is screwed into the top of the fixing plate 201. When the bolt is tightened, the soft rubber pad 6 at the bottom of the auxiliary plate 5 is deformed under pressure. Through elastic deformation, it fills the gap between the auxiliary plate 5 and the processed plate, and at the same time generates frictional resistance, suppressing the vibration or displacement of the auxiliary plate 5, fixing the long plate, and improving the overall structural rigidity.

[0022] like Figure 1As shown, the outer side of the vacuum suction cup 205 is provided with a lip 7 for assisting the vacuum suction cup 205. The thickness of the lip 7 is 2mm. The top of the lip 7 is at the same level as the top of the vacuum suction cup 205. The top surface of the flexible lip 7 on the outer edge of the vacuum suction cup 205 is flush with the suction cup. When adsorbing the board, the lip 7 first adheres to the surface of the board and undergoes slight deformation to form a temporary sealed space, which greatly reduces air leakage. This allows the vacuum pump 203 to quickly increase the negative pressure time, shorten the adsorption time, and reduce energy consumption.

[0023] like Figure 3 As shown, a slide rail 8 is bolted inside the placement basket 202, and an extension rod 9 is slidably connected inside the slide rail 8. One end of the extension rod 9 extends and passes through to the outside of the placement basket 202. The slide rail 8 fixed inside the placement basket 202 and the extension rod 9 slide in cooperation. By manually pulling the extension rod 9 out of the basket, the connected vacuum suction plate 204 can be moved laterally, thereby adjusting the coverage area of ​​the suction cup group to adapt to the positioning requirements of different sized boards. After adjustment, locking the extension rod 9 will fix the position.

[0024] like Figure 1 and Figure 5 As shown, laser protractors 10 are installed on both sides of the top of the fixed plate 201. The laser protractors 10 are located at the connection between the fixed plate 201 and the bending machine body 1. The laser protractors 10 are controlled by the Internet of Things (IoT). The laser protractors 10 on both sides of the top of the fixed plate 201 project high-precision angle marks onto the bending area. Before bending, the laser forms a visible reference line on the surface of the plate. During the bending process, the angle data is transmitted to the IoT terminal in real time through the IoT. The operator can dynamically correct the bending parameters based on this to ensure the angle accuracy.

[0025] like Figure 1 and Figure 5 As shown, a support frame 11 is bolted to the bottom of the fixed plate 201. A hydraulic damper 12 is installed inside the support frame 11. The support frame 11 is located on one side of the placement basket 202. One end of the support frame 11 is bolted to one side of the bending machine body 1. The two ends of the support frame 11 are respectively bolted to the bottom of the fixed plate 201 and the bending machine body 1. The hydraulic damper 12 inside is filled with viscous fluid. When the bending impact is transmitted to the fixed plate 201, the damper piston squeezes the fluid to generate reverse resistance, converting mechanical vibration into heat energy consumption, effectively attenuating the vibration amplitude, and protecting it from interference.

[0026] Specifically, in use, this high-accuracy metal bending mechanism works as follows: the fixed plate 201 connects to the bending machine body 1, and the air pump 203 in the basket 202 below it draws air from the vacuum suction plate 204 to create negative pressure, causing the top vacuum suction cup 205 to adsorb the sheet material (see...). Figure 2 and Figure 5 ); The barometer 206 monitors the adsorption pressure in real time and provides feedback via the Internet of Things, dynamically adjusting the power of the air pump 203 (see Figure 2 and Figure 3 Electromagnet 301 is linked by PLC control component 302 and voltage sensor 303 (see...) Figure 3 The suction cup applies an auxiliary magnetic force to the ferromagnetic sheet material. The flexible lip 7 forms a temporary seal when the suction cup contacts the sheet material, accelerating the establishment of negative pressure. The slide rail 8 and extension rod 9 can be used to adjust the position of the suction cup laterally to accommodate different sheet material sizes. The laser protractor 10 projects real-time angle markings and transmits data via the Internet of Things (see...). Figure 1 and Figure 3 The hydraulic damper 12 inside the support frame 11 converts the bending impact into thermal energy for shock absorption, while the soft rubber pad 6 at the bottom of the auxiliary plate 5 further suppresses vibration through friction buffering. Finally, the IoT hub coordinates air pressure, magnetic force, and angle data to form an overall control system, ensuring zero deviation of the material throughout the bending process.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
