[0060] It is further illustrated that Figure 4 The inner side wall of the C-shaped frame is further provided with a drag chain support plate 4 extending in the first direction. The two sides of the drag chain support plate 4 are respectively provided with a drag chain limiting plate 5 extending in the first direction. The drag chain support plate 4 and the two drag chain limiting plates 5 on the two sides form a groove structure, which facilitates the arrangement and fixation of the cable. Figure 9 The top end of the material blocking plate 32 is provided with an upper partition plate 6 made of sheet metal. When the steel bar is blanked, the upper partition plate 6 is used to protect the top end of the material blocking plate 32 and support the blanked steel bar. The bottom beam 12 is provided with a lower partition plate 7 arranged on the top of the bottom beam 12, which is used to block the surface scale of the steel bar and limit the lowest rotating position of the guide strip 34. The side of the bottom beam 12 facing the bent hook unloading mechanism 31 is provided with an air pipe groove 8, and the air supply pipe and cable of the bent hook air cylinder 3123 can be arranged along the air pipe groove 8.

[0061] The steel bar multifunctional unloading device provided by the above embodiment is used to perform steel bar multifunctional unloading through the following steps:

[0062] S1, the steel bar is located in the blanking conversion assembly 2;

[0063] Specifically, as shown in Figure 6 The steel bar is located between the first unloading door 22 and the fixed angle steel 226. The first unloading door 22 has openings at both ends, which facilitates the alignment of the steel bar at both ends.

[0064] S2, the steel bar is blanked in batches from the blanking conversion assembly 2;

[0065] S3, when the bent hook 312 is lower than the surface of the material blocking plate 32, the steel bar slides downward along the material blocking plate 32 for unloading. When the bent hook 312 is rotated to be higher than the surface of the material blocking plate 32, the bent hook 312 collects the steel bar for packaging and unloading.

[0066] In the above steel bar multifunctional unloading steps, the blanking conversion assembly 2 realizes accurate control of the number of steel bars by blanking in batches, so as to meet different process requirements, such as the number control of two steel bars for simultaneous bending. The unloading and collecting assembly 3 realizes multifunctional unloading of the steel bar by arranging the bent hook unloading mechanism 31 and the material blocking plate 32, such as directly sliding the steel bar downward along the material blocking plate 32 for unloading, rotating the bent hook 312 to be higher than the material blocking plate 32 for batch packaging and unloading of the steel bar, thereby improving the production efficiency of the steel bar and meeting different unloading requirements.

[0067] Specifically, step S2 includes the following steps:

[0068] S21, the first unloading door 22 of the blanking conversion assembly 2 is opened, and one steel bar is controlled to fall into the second unloading door 23 and then the first unloading door 22 is closed;

[0069] S22, the second discharge door 23 is opened, and one steel bar falls into the third discharge door 24, and then the third discharge door 24 is closed;

[0070] S23, the step S21 and the step S22 are repeated until the number of the steel bars at the third discharge door 24 meets the requirement;

[0071] S24, the fourth discharge door 25 of the material falling conversion assembly 2 is rotated towards the side away from the third discharge door 24;

[0072] S25, the third discharge door 24 is opened, and the steel bar slides downwards along the guide bar assembly and the material blocking plate 32 to fall.

[0073] Generally, the steel bar bending machine can realize the simultaneous bending production of more than two steel bars, therefore, by arranging the second discharge door 23 and the third discharge door 24, when the number of the steel bars at the third discharge door 24 meets the bending requirement, the third discharge door 24 controls the steel bar bending machine to feed, the feeding precision is easy to control, the automatic feeding is high in efficiency. When the bending is not needed, the first discharge door 22, the second discharge door 23 and the third discharge door 24 are sequentially rotated to open to discharge, so that the steel bars fall into the hook unloading mechanism 31 one by one to be discharged and collected, and can be directly collected and loaded or packed step by step, so as to avoid the cross caused by the simultaneous discharge of multiple steel bars, and to avoid the jamming.

[0074] During the unloading operation, the rotation angle of the fourth discharge door 25 is matched with the positions of the steel bar bending machine and the hook unloading mechanism 31, when the output rod of the fourth cylinder 254 is extended, the fourth discharge door 25 guides the steel bar into the steel bar bending machine in the C-shaped beam 13 to realize the bending feeding. During the bending, the guide bar assembly is rotated to support the middle position of the steel bar. When the output rod of the fourth cylinder 254 is retracted, the fourth discharge door 25 is rotated downwards, the steel bar bending machine closes the feeding opening, the steel bar falls onto the guide bar assembly and the material blocking plate 32 along the fourth discharge door 25 to realize the unloading and collection or the packing collection of the steel bar.
