[0002] Aluminum tube refers to a metal tubular material made of pure aluminum or aluminum alloy that is processed into a hollow metal tube along the entire longitudinal length. It can have one or more closed through holes, with uniform wall thickness and cross-section, and is delivered in a straight line or in a coil. Cold drawing is a material processing technology. For metal materials, cold drawing refers to drawing the material at room temperature in order to achieve a certain shape and certain mechanical properties. Cold-drawn products have the advantages of high dimensional accuracy and good surface finish compared to hot-formed products.

[0003] Among them, it was found through searching that the patent application number CN202120958236.1 discloses an automatic feeding cold drawing machine for aluminum tubes, including a base, a cold drawing device is connected to the right end of the feeding rack, a feeding box is connected to the top of the support frame, a steering wheel is rotatably connected to the upper end of the bogie, a storage cavity is opened on the circumferential outer wall of the steering wheel, a guide rail is connected between the bogie and the feeding rack, a plurality of groups of support rollers are rotatably connected to the upper part of the feeding rack, a plurality of groups of drive shafts are rotatably connected to the lower part of the inner cavity of the U-shaped seat, a pressure roller is connected to the circumferential outer wall of the drive shaft, a bevel gear 1 is connected to the right end of the drive shaft, and a mounting frame is connected to the right side wall of the U-shaped seat;

[0004] When this structure is in use, the triangular seat is used for limiting and guiding, so that the aluminum tube is filled in the stroke channel, the outer wall of the steering wheel blocks the discharge port, and the worm gear is driven by the worm gear to make the steering wheel rotate clockwise on the upper part of the bogie. However, this structure is difficult to ensure the stability of the aluminum tube when loading, and it is not easy to guide the aluminum tube during cold drawing, resulting in inaccurate cold drawing.
