Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an automatic bending device. Background Technology

[0002] A rebar bending machine is a type of rebar processing machinery. Its working mechanism is a horizontal working disc that rotates on a vertical axis. The rebar is placed at the position shown by the dotted line in the diagram. The support pin is fixed on the machine tool, and the center pin and bending pin are mounted on the working disc. When the disc rotates, it bends the rebar. In order to bend rebars of various diameters, there are several holes on the working disc for inserting the bending pin. The center pin of different diameters can also be replaced accordingly.

[0003] Existing bending machines require more time and manpower for manual feeding and transport of curved wires, making it impossible to achieve a continuous and rapid production process. Different workers may have different operating methods and strengths, making it impossible to achieve standardized production of products, thus affecting product consistency and brand image. The inability of bending machines to automatically feed and transport curved wires will have a negative impact on production efficiency, cost, quality, and stability. Utility Model Content

[0040] Reference Figures 1-4 Based on the same concept as Embodiment 1 above, this embodiment also proposes that the steel bar clamping end 204 and the steel bar clamping adjustment end 205 are correspondingly and matched. A bending machine 4 is provided on one side of the steel bar conveying mechanism 2. An electrical cabinet is provided on the front side of the bending machine 4. A flat receiving rack 5 is provided on one side of the bending machine 4. A receiving bin 6 is provided on the side of the flat receiving rack 5. This can quickly and orderly collect the processed steel bars, avoiding the tedious process of collecting them one by one manually, saving time.

Through the design of the receiving mechanism, steel bars of different specifications and batches can be classified, stored and counted, which is convenient for subsequent quality traceability and inventory management.

[0041] Specifically, the working process or working principle of the automatic bending device is as follows: First, the initial material is loaded manually, that is, the steel bars are placed on the manual loading rack 1. The manual loading rack 1 is equipped with a conveyor belt and an auxiliary shaft that are connected to the connecting shaft 303. By operating the relevant electronic components in the control cabinet, the steel bars will automatically roll to the stepped loading mechanism 3, which drives the variable frequency motor 306 to drive the reducer 305. The reducer 305 and the connecting shaft 303 are rotatably connected, and the connecting shaft 303 drives the eccentric wheel 304 to rotate. Under the action of the passive guide wheel 307, the intermediate support frame 316 moves up and down, and then the moving washboard 309 moves relative to the fixed washboard 310. During the relative movement of the two, the steel bars are lifted. The adjustment plate 311 can be manually set to make fine adjustments to the moving washboard 309. After the material is loaded, it enters the steel bar conveying mechanism 2 and moves forward under the action of the steel bar support and transport rod 203. After entering the bending machine 4, the steel bars are processed and finally fall into the receiving bin 6.

[0042] It should be noted that the variable frequency motor 306, the reducer 305, and the sensor 312 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail here.
