The lateral conveying mechanism includes two rolling shafts 121 arranged oppositely left and right and two chains 122 arranged at intervals front and back. The rolling shafts 121 are cooperatively connected with the ends of the chains 122 to drive the chains to rotate, and further drive the bars to move laterally. The setting of the chains can avoid the slipping of the bars and ensure the stability of the conveying.

[0029] The longitudinal movement is located on one side of the conveying direction of the lateral mechanism. It includes two rollers arranged oppositely front and back, which are used to receive the bar 100 and push the bar forward to the straightening device. Its height is lower than the top surface height of the chain. The extending direction of the central axis of the rollers is the left-right direction. The outer periphery of the rollers is provided with a limiting groove for guiding and correcting the position of the bar. During operation, the rollers rotate to drive the bar to move forward.

[0030] The bar conveying device further includes a baffle 14 vertically installed on the bracket. The baffle 14 is located on one side of the rollers to assist the rollers in limiting the bar. In this embodiment, the baffle is located between the front and rear rollers.

[0031] The bar conveying device further includes two inclined guiding blocks 13. Each inclined guiding block 13 is installed on the bracket and is located between the corresponding chain and the corresponding roller. When the bar moves to one end of the chain, the bar slides down along the inclined surface of the inclined guiding block onto the roller.

[0032] To further ensure the stability of the conveying and avoid the jumping of the bar, the bar conveying device further includes a pressing mechanism 15 for pressing down the bar. The pressing mechanism includes a support frame 151, a driving cylinder 152 and a swinging pressure roller 153. Specifically, the support frame is installed at the rear of the front roller. The swinging pressure roller has a pivoting portion, a connecting portion and a pressing portion located at both ends respectively. The pivoting portion is hinged to the top of the support frame. The driving cylinder is installed on the side of the support frame away from the lateral conveying mechanism, and its top is connected to the connecting portion to drive the lifting of the connecting portion so as to drive the pressing portion to swing. The outer periphery of the pressing portion is provided with a bearing sleeve 154 for pressing down the bar. When the bar has not fallen onto the roller, the pressing mechanism is opened and the pressing portion is in the lifted state. When the bar falls onto the roller, the driving cylinder lifts to drive the pressing portion to press down the bar to stabilize the up and down position of the bar.
