[0031] Example 2

[0032] See also Figure 5 On the basis of Example 1, a motor 712 is installed in the middle position inside the round table 71, and one end of the output shaft of the motor 712 is fixedly connected to one end of the rotating shaft of the rotating table 711.

[0033] Working principle:

[0034] The fixed clamp 2 clamps one end of the metal bar 5, and the movable clamp 4 is put on the other end of the metal bar. The position of the movable clamp 4 is adjusted according to the length of the bar. After adjustment, the movable clamp 4 is connected and fixed to the processing table 1 by the positioning bolt 10. The two clamps are used together to firmly fix the bar on the processing table. In the traditional bending process, workers need to hold the bar by hand for processing, which has safety hazards during the bending process. By clamping the bar with two clamps, the workers' hands are freed, and the bending process is safer.

[0035] After the bar is fixed, the bending assembly 7 is moved according to the length of the bar and the bending position. The bending assembly moves to the position where the bar needs to be bent and inserts one end of the bar into the gap between the first cylinder 75 and the second cylinder 79. The motor 712 is started to rotate the rotating table 711 and drive the second column 710 to rotate in one direction in the annular groove 74 to squeeze and bend the metal bar.

[0036] The positions of the movable clamp 4 and the bending component 7 in the device are adjustable, which is convenient for adapting to the processing needs of bars of different lengths. At the same time, one end of the metal bar can also be clamped only by the movable clamp 4. During use, the movable clamp 4 can be continuously moved toward the side close to the bending component 7, thereby realizing the function of continuous feeding and improving processing efficiency. Similarly, the bending component 7 can also be continuously moved toward the side close to the movable clamp 4, which can also achieve the purpose of uninterrupted processing.
