[0013] Compared with the prior art, the present invention provides a cutting bar feeder, which has the following advantages: By incorporating a series of components including limit slides, mounting bases, a bottom plate, feeding slides, side plates, a feed inlet, a mounting plate, slide positioning plates, fixing slots, a second slot, and recessed holes, the internal array of limit slides in the feeding bin precisely limits the movement of the bar stock entering the bin. During bar stock feeding, the limit slides prevent swaying or deviation within the bin, ensuring the bar stock moves smoothly along a predetermined path, guaranteeing straightness and stability, improving feeding accuracy, and consequently enhancing the accuracy of cutting processes. The bottom of the feeding bin is equipped with a mounting... The base provides a stable support foundation for the feeding hopper. The mounting base is connected to the mounting plate and slide bar positioning plate through the cooperation of the second slot, bolt holes and fixing slots. During equipment installation and commissioning, it is convenient to adjust and calibrate the position. During long-term use, it can withstand the impact and vibration during bar feeding and is not prone to loosening, thus extending the service life of the equipment. The slide bar positioning plate has a ring array of holes corresponding to the limit slide bars, which can further accurately position the limit slide bars and ensure the verticality and spacing accuracy of the limit slide bars.

[0014] The base plate features a first slot, an L-shaped mounting block, a feeding slide bar, a fixing slot, a mounting strip, and an embedded groove. The first slot is arrayed inside the base plate, and the L-shaped mounting block is connected to the base plate via this slot. This snap-fit ​​connection method is very convenient for installing the L-shaped mounting block, allowing for quick positioning and ensuring accurate and consistent installation. Furthermore, the snap-fit ​​structure has a certain pre-tightening force, which stabilizes the position of the L-shaped mounting block during initial equipment operation, preventing it from easily shaking. A fixing groove is provided inside the first slot, and bolt holes are provided at the bottom of the L-shaped mounting block. The two are fixedly connected by bolts, further strengthening the connection between the L-shaped mounting block and the base plate. For stability, during the operation of the feeder, the feeding slide rod carries and transmits the bar stock, which generates a certain amount of vibration and impact. The bolt fixing structure can effectively resist these external forces, ensuring that the L-shaped mounting block is always firmly installed on the base plate, thus ensuring the stability of the feeding slide rod and ensuring a smooth bar stock feeding process. The top of the L-shaped mounting block is equipped with a mounting strip, and the groove at the bottom of the mounting strip is fixedly connected to the L-shaped mounting block through the internal bolt holes. The inner side of the mounting strip is also equipped with a recessed hole. The mounting strip can not only further stabilize the feeding slide rod, but also play an auxiliary positioning and support role through the inner recessed hole with the feeding slide rod, reducing the deformation and shaking of the feeding slide rod during feeding.
