When the adjusting mechanism moves to a suitable position, the transparent plate is pulled to move in the connecting mechanism, so that when bending the steel bars, the operators around the device can be protected, and the steel bars are passed through the contact mechanism and enter the positioning component, so that the bending component can bend the steel bars; Preferably, the adjustment mechanism comprises a fixed block, the side of the fixed block is fixedly connected to the connecting plate, the bottom of the fixed block is fixedly connected to the output end of the lifting mechanism, the inner side of the fixed block is fixedly connected to a motor, the output end of the motor is fixedly connected to the connecting block, and the side of the connecting block is fixedly connected to the connecting mechanism; After the fixed block drives the height of the protective plate and the connecting plate to be determined, the motor can be turned on so that the output end of the motor drives the connecting mechanism to move upward through the connecting block, thereby adjusting the support height of the connecting mechanism, thereby appropriately adjusting the height of the transparent plate to avoid interference between the steel bar and the transparent plate when the steel bar is bent and rotated; Preferably, the contact mechanism comprises two contact frames, the contact frames are fixedly connected to the side surfaces of the connecting plate, the upper and lower sides of one of the contact frames are rotatably connected with ball bearings, the inner side of the contact frame is slidably connected with a slide rod, the end of the slide rod away from the contact frame is fixedly connected with a contact sleeve, the side surface of the contact sleeve is slidably connected to the inner side of the contact frame, a first spring is sleeved on the slide rod, one end of the first spring is fixedly connected to the side surface of the contact sleeve, the other end of the first spring is fixedly connected to the inner side of the contact frame, both sides of the contact sleeve are fixedly connected with contact plates, and both sides of the contact plate are provided with clearance grooves; After adjusting the position of the transparent plate, one end of the steel bar is passed through, and the middle of the two contact frames enters the positioning component. Ball bearings are arranged on the inner side of the contact frames, thereby reducing the friction between the steel bar and the contact frames during the feeding process. The ball bearings are arranged on the inner side of the contact frame to reduce the friction between the steel bar and the contact frame when feeding, so that the steel bar can enter the positioning component more smoothly. At the same time, it can also speed up the entire steel bar processing process and improve construction efficiency. At the same time, when the steel bar passes through the contact frame, the side of the steel bar contacts and moves with the contact plates on both sides, thereby cleaning the side of the steel bar.

The side of the connecting plate 24 is fixedly connected with an adjusting mechanism 23. The output end of the lifting mechanism 21 is fixedly connected to the bottom of the adjusting mechanism 23. The output end of the adjusting mechanism 23 is fixedly connected with a connecting mechanism 28. The inner side of the connecting mechanism 28 is slidably connected with a transparent plate 25. Both sides of the transparent plate 25 are fixedly connected with a collecting mechanism 27. The side of the connecting plate 24 is fixedly connected with a contact mechanism 26. Specifically, when bending the steel bar, the lifting mechanisms 21 on both sides are opened, and the adjusting mechanism 23 is driven by the output end of the lifting mechanism 21 to move upward, so that the adjusting mechanism 23 drives the connecting plate 24 and the protective plate 22 to move upward. When the adjusting mechanism 23 moves to a suitable position, the transparent plate 25 is pulled to move in the connecting mechanism 28, so that when bending the steel bar, the operators around the device can be protected, and the steel bar is passed through the contact mechanism 26 and enters the positioning component 3, so that the bending component 4 can bend the steel bar; See also Figure 1-Figure 5 The adjusting mechanism 23 includes a fixed block 231, a side of the fixed block 231 is fixedly connected to the connecting plate 24, a bottom of the fixed block 231 is fixedly connected to the output end of the lifting mechanism 21, a motor 232 is fixedly connected to the inner side of the fixed block 231, a connecting block 233 is fixedly connected to the output end of the motor 232, and a side of the connecting block 233 is fixedly connected to the connecting mechanism 28; Specifically, after the fixing block 231 drives the height of the protective plate 22 and the connecting plate 24 to be determined, the motor 232 can be turned on so that the output end of the motor 232 drives the connecting mechanism 28 to move upward through the connecting block 233, thereby adjusting the support height of the connecting mechanism 28, thereby appropriately adjusting the height of the transparent plate 25, and avoiding interference between the steel bar and the transparent plate 25 when the steel bar is bent and rotated; See also Figure 1-Figure 7The contact mechanism 26 includes two contact frames 261, which are fixedly connected to the side of the connecting plate 24.

Specifically, after adjusting the position of the transparent plate 25, one end of the steel bar is passed through, and the middle of the two contact frames 261 enters the positioning component 3. The ball bearings 262 are arranged on the inner side of the contact frames 261, thereby reducing the friction between the steel bar and the contact frames 261 during the feeding operation. The ball bearing 262 is arranged inside the contact frame 261, which can reduce the friction between the steel bar and the contact frame 261 when feeding, so that the steel bar can enter the positioning component 3 more smoothly, and at the same time, it can also speed up the speed of the entire steel bar processing process and improve the construction efficiency; At the same time, when the steel bar passes through the contact frame 261, the side of the steel bar contacts and moves with the contact plates 266 on both sides, thereby cleaning the side of the steel bar. When the contact plate 266 contacts and cleans the steel bar, when the contact extrusion force between the contact plate 266 and the steel bar is greater than the tensile force of the first spring 265, the first spring 265 contracts, and at the same time, the contact plate 266 moves toward the inner side of the contact frame 261 through the slide bar 263. At the same time, the buffering work of the first spring 265 avoids excessive extrusion force between the contact plate 266 and the steel bar, thereby preventing friction damage to the side of the steel bar, preventing the mechanical properties of the steel bar from being reduced due to surface damage, and ensuring the bearing capacity and durability of the steel bar in the building structure.
