[0028] To further elaborate, the Y-axis conveying device 9 includes two sprockets 11, a chain 12 and multiple mounting platforms 13. The two sprockets 11 are rotatably connected to the two ends of the sliding support frame 8 respectively. The multiple mounting platforms 13 are evenly installed on the chain 12. The mounting platform 13 is provided with a groove 14 for placing the steel bars. The steel bars in this application need to be processed into a mouth shape in advance to prevent only half or one quarter of the steel bars from being in the groove 14, and the rest of the steel bars are in the air, which is convenient for filling and clamping. At the same time, one of the sprockets 11 is provided with a driving motor for driving, which is not drawn in the figure.
