[0067] The setting of the limit plate 402 can limit the lifting plate 409, ensuring that the sliding member 407 can move downward while moving, thereby removing the restriction on the cut bar material, greatly ensuring the normal operation of the device.

[0068] As an optimization solution of the present invention, Fig. 9 As shown, it also includes a lifting piece 7, which includes a lifting rod 701 and a plurality of connecting plates 702 installed at the bottom of the lifting rod 701, the plurality of connecting plates 702 are evenly distributed at the bottom of the lifting rod 701, and the connecting plates 702 are connected to the mounting frame 1, a groove 703 is opened at the top of the lifting rod 701, the conveyor belt 307 is set in the groove 703, and the conveyor belt 307 is slidably matched with the groove 703.

[0069] The setting of the lifting member 7 can lift the bar material and limit the downward movement of the bar material, thereby ensuring that the bar material is always in a stable state during the cutting process, thereby greatly improving the cutting efficiency and cutting quality of the bar material.

[0070] As an optimization solution of the present invention, Figure 1As shown, it also includes a protective cover 5 and a loading plate 6. The protective cover 5 is arranged on one end of the mounting frame 1 away from the unloading mechanism 8. The loading plate 6 is arranged above the mounting frame 1, and the loading plate 6 is connected to the protective cover 5. Through holes are opened on both sides of the center line of the lower end of the loading plate 6, and the through holes cooperate with the conveyor belt 307 and the baffle 308.

[0071] The setting of the protective cover 5 can protect the first rotating shaft 305 and the third sprocket 306, ensuring the safety and stability of the first rotating shaft 305 and the third sprocket 306 during operation. The setting of the loading plate 6 can serve the purpose of loading the bar material, greatly improving the loading efficiency and quality of the bar material.

[0072] The working process is as follows:

[0073] The bar is placed on the loading plate 6, and the bar slides down from the loading plate 6 to the lifting rod 701. The baffle plate 308 drives the bar to move with the conveyor belt 307. While the bar moves, it cooperates with the vertical plate 408 on the clamping mechanism 4 to fix the bar. While the bar moves with the conveyor belt 307, it drives the vertical plate 408 to move along the guide rod 405. While the slider 4010 moves with the vertical plate 408, it compresses the first spring 406. When the side wall of the bar contacts the cutting knife 2012, the end of the limit plate 402 contacts the side wall of the lifting plate 409. As the bar continues to move forward, while the cutting knife 2012 cuts the bar, the lifting plate 409 is driven by the limit plate 402 to move. And the vertical plate 408 moves downward, the lifting plate 409 and the vertical plate 408 will compress the second spring 4012 while moving. When the bar cutting is completed, the top of the vertical plate 408 moves to the bottom of the bar, and under the action of the conveyor belt 307, it can drive the bar to move toward the lower feeding mechanism 8. In the absence of bar limitation, under the action of the first spring 406 and the second spring 4012, the vertical plate 408 is reset, and the bar at the next baffle 308 is limited, thereby achieving the purpose of clamping the next bar. Such reciprocating motion can continuously clamp and fix the bar, ensuring the safety and stability of the bar during the cutting process, and greatly ensuring the cutting efficiency and quality of the bar.
