[0019] Please see Figure 1-3 The embodiments of this utility model are described in detail below.

[0020] Example: See Figure 1 As shown, the adjustable discharge rack for a cold-rolled tube mill includes a frame body 1. The frame body 1 comprises a frame structure consisting of a bottom crossbeam 14, a front column 2, a middle column 3, a rear column 4, a crossbeam 5, and an inclined beam 6. The front column 2, middle column 3, crossbeam 5, and inclined beam 6 enclose a receiving space 7 for collecting tubes that roll off the inclined top plate 10.

[0021] See Figure 2 and3 As shown, support plates 8 are provided on both sides of the upper part of the central column 3 and the rear column 4. The two support plates 8 are used to support the opposite ends of two adjacent V-shaped long support plates 9. The height of the V-shaped long support plates 9 is adjustable; for details, please refer to [reference needed]. Figure 3 As shown, an adjusting screw 18 is fixed to the lower end of the V-shaped long support plate 9. The support plate 8 has a screw inlet / outlet hole 21. A gate-shaped limiting block 19 is fixed to the upper part of the screw inlet / outlet hole 21. An adjusting nut 20 is placed inside the gate-shaped limiting block 19 for positioning. The adjusting screw 18 passes through the hole at the top of the gate-shaped limiting block 19, screws with the adjusting nut 20, and extends into the screw inlet / outlet hole 21. The gate-shaped limiting block 19 restricts the adjusting nut 20 to rotate only. By rotating the adjusting nut 20, the adjusting nut 20 moves the adjusting screw 18 up and down through its threaded structure, thus adjusting the height of the V-shaped long support plate 9 to accommodate pipes of different diameters.

[0022] See Figure 1 As shown, an inclined top plate 10 is provided between the two support plates 8. The inclined top plate 10 is used to lift the pipe above the V-shaped long support plate and guide it to roll into the receiving space 7. A cylinder 11 is provided on the rear side of the rear column 4. The lower end of the cylinder 11 is hinged to a cylinder seat fixed on the rear column 4. The piston rod of the cylinder 11 is connected to a push rod 15, which is fixedly connected to the rear end of the inclined top plate 10. A spring 17 is sleeved on the push rod 15. The spring 17 is located on the upper and lower sides of the inclined top plate 10 to buffer the movement of the inclined top plate 10 and reduce impact and noise. The push rod 15 passes through a hole in the guide plate 12 fixed on the rear column 4. The guide plate 12 is used to guide the push rod 15 to ensure smooth movement.

[0023] The lower part of the frame 1 is equipped with an oil collection tray 13 for collecting oil stains.

[0024] The V-shaped long support plate 9, the inclined top plate 10, and the positions on the frame 1 that contact the pipes are all equipped with removable flexible pads 16. The flexible pads 16 are detachably connected by screws, facilitating replacement and maintenance. Preferably, the flexible pads 16 are made of rubber or plastic.

[0025] Working principle: The cold rolling mill continuously outputs finished tubes, which are initially supported by a V-shaped long support plate 9. Once the tube has completely left the mill, cylinder 11 activates, pushing the push rod 15 and inclined top plate 10 upwards, lifting the tube above the V-shaped long support plate 9 and rolling it along the inclined surface of the inclined top plate 10 into the receiving space 7. A spring 17 buffers the vibration of the inclined top plate 10, reducing impact. The height of the V-shaped long support plate 9 can be adjusted to accommodate tubes of different specifications. A flexible pad 16 protects the tube surface, and an oil collection tray 13 collects oil, maintaining a clean working environment. This invention has a reasonable structure, is easy to operate, and is suitable for continuous output cold rolling mill production lines. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
