[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-7 To address the issue of machining debris falling onto the machine tool, requiring subsequent collection by staff—a time-consuming and inefficient process—the following preferred technical solutions are provided:

[0034] A semi-solid hollow shaft spinning machine includes an outer frame 1 and a hydraulic system control panel 2 disposed on the outer wall of the outer frame 1. A processing base plate 3 is installed at the lower end of the outer frame 1, and a spinning processing body 4 is installed on the inner wall of the outer frame 1. A movable body 5 is correspondingly disposed at one end of the spinning processing body 4. A hydraulic chuck 6 is installed at the end of the movable body 5 near the spinning processing body 4. A slide table 7 is slidably connected to the lower end of the movable body 5. A collection box assembly 8 is slidably connected to the inner wall of the processing base plate 3. Multiple sets of slits are opened at the upper end of the processing base plate 3 for discharging debris.

[0035] The collection box assembly 8 includes an outer box 81 that is slidably connected to the inner wall of the processing base plate 3. A middle partition mesh 82 is slidably connected to one side of the inner wall of the outer box 81. The upper end of the middle partition mesh 82 is an upper cavity 83, and the lower end of the middle partition mesh 82 is a lower cavity 84.

[0036] Specifically, during the forming process of the semi-solid hollow shaft, one end is fixed using a hydraulic chuck 6, and the shaft is spun into shape by the spinning processing body 4. Through the cooperation of the movable body 5 and the slide table 7, the hydraulic chuck 6 and the semi-solid hollow shaft can be moved to better coordinate the processing. The debris after the semi-solid hollow shaft is spun into shape will fall from the gap on the processing base plate 3 into the cavity of the outer box 81, achieving the purpose of debris collection. No further collection is required, reducing subsequent processing time. In addition, through the cooperation of the partition mesh 82, larger debris can be left in the upper cavity 83, and smaller debris can be filtered into the lower cavity 84, which is convenient for classified collection and provides convenience for the staff.

[0037] To improve the filtration efficiency of the intermediate mesh, the following preferred technical solutions are provided:

[0038] A guide inclined block 85 is fixedly connected to one side of the partition net 82. The guide inclined block 85 is slidably connected to the inner wall of the outer box 81. The lower end of the guide inclined block 85 is connected to the pressure block body 86. The inner wall of the pressure block body 86 is slidably connected to the shrinking inner rod 87. The outer wall of the shrinking inner rod 87 is sleeved with a return spring 88. One end of the pressure block body 86 is slidably connected to the inner wall of the outer box 81, and the other end of the pressure block body 86 is provided with a movable groove 89. The inner wall of the movable groove 89 is slidably connected to a central connecting bent rod 810. One end of the central connecting bent rod 810 is fixedly connected to the partition net 82, and the other end is fixedly connected to the pressure block body 86.

[0039] Specifically, when debris falls from the gap in the processing base plate 3 into the upper end of the partition screen 82, its falling gravity causes the partition screen 82 to push down the pressure block body 86 through the central connecting rod 810. This compresses the return spring 88 to a taut state, and the reaction force of the return spring 88 drives the partition screen 82 to move upward. This process repeats, causing the partition screen 82 to vibrate continuously, thus accelerating the filtration efficiency of the debris.

[0040] To ensure that debris can enter the gaps, the following preferred technical solutions are provided:

[0041] The main body 5 is equipped with a hydraulic chuck 6. A first connecting rod 9 and a second connecting rod 10 are installed on the outer wall of the lower part of one end. The first connecting rod 9 and the second connecting rod 10 are symmetrically distributed about the center of the main body 5. A pusher assembly 11 is fixedly connected to the end of the first connecting rod 9 and the second connecting rod 10 away from the main body 5. The pusher assembly 11 is used to push the debris into the gap.

[0042] Specifically, after the semi-solid hollow shaft is formed, the movable body 5 and the slide table 7 work together to move the hydraulic chuck 6 and the semi-solid hollow shaft away from the spinning processing body 4. Then, the semi-solid hollow shaft is removed. While moving away from the spinning processing body 4, the movable body 5 will pull the first connecting rod 9 and the second connecting rod 10, which will pull the pusher assembly 11 to push the debris on the processing base plate 3 and help the debris enter the gap. The effect is significant.

[0043] The pusher assembly 11 includes a vertical connecting plate 111 fixedly connected to the first connecting rod 9 and the second connecting rod 10. A horizontal connecting plate 112 is fixedly connected to the lower end of the vertical connecting plate 111. The lower end of the horizontal connecting plate 112 is slidably connected to the processing base plate 3. An inclined push plate 113 is hinged to one end of the horizontal connecting plate 112.

[0044] A middle connector 114 is provided at one end of the inclined push plate 113 away from the horizontal connecting plate 112. An installation groove is provided on one side of the middle connector 114. An elastic element 115 is fixedly connected in the installation groove. One end of the elastic element 115 is fixedly connected to the inclined push plate 113.

[0045] Specifically, when the first link 9 and the second link 10 pull the pusher assembly 11, the inclined pusher plate 113 will push the material. At this time, the weight of the accumulated debris will squeeze the inclined pusher plate 113. The inclined pusher plate 113 has elastic space through the cooperation of the elastic element 115, making it more resilient.

[0046] To further explain the above embodiments, the present invention also provides an implementation method, a forming method of a semi-solid hollow shaft spinning machine, comprising the following steps:

[0047] Step 1: Select a solid bar and drill through one end with a drill bit;

[0048] Step 2: Fix one end of the conductive solid bar workpiece using hydraulic chuck 6, and heat it using high frequency, controlling the heating temperature to 680-730℃;

[0049] Step 3: When the workpiece temperature is heated to 680-730℃, it is spun into shape by the spinning processing body 4. Through the cooperation of the movable body 5 and the slide table 7, the hydraulic chuck 6 and the semi-solid hollow shaft can be moved to better cooperate in processing. The formed debris will fall into the cavity of the outer box 81 from the gap on the processing base plate 3. Through the cooperation of the middle partition 82, the larger debris can be left in the upper cavity 83, and the smaller debris can be filtered into the lower cavity 84 for easy classification and collection.

[0050] Step 4: Place the spun workpiece into a normalizing furnace and heat it for a period of time. Then, let it cool to room temperature with the furnace. Use a drill bit to drill through the other end of the workpiece and machine the inner hole to the corresponding size. Finally, machine the outer shape of the workpiece to the size required by the drawing.
