That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a wire drawing machine spindle cooling device of the present invention comprises an outer tube 1 and a plurality of fan-shaped blocks 5, wherein the fan-shaped blocks 5 are combined in an annular structure to form a spindle, a groove is provided in the middle of the fan-shaped block 5, and a plurality of grooves are combined to form a cooling cavity 16, cooling grooves are provided on both sides of the fan-shaped block 5, and adjacent cooling grooves are combined to form a cooling channel 15 connected to the cooling cavity 16, the outer tube 1 is sleeved on the outside of the spindle, and seals are installed at both ends of the outer tube 1, and an annular channel is formed between the seal, the outer tube 1 and the spindle, and a shell 10 is installed on the outside of the outer tube 1, one above and one below, and the lower shell 10 is connected to the outside, and a push block 6 is provided, and a piston is installed on the push block 6.

[0027] In this embodiment, the sealing components include a sealing ring 2, a sealing bearing 3 and a plurality of screws. The open end surface of the outer tube 1 is recessed to form an annular mounting groove 12. The sealing ring 2 is arranged in the annular mounting groove 12. The sealing bearing 3 is installed in the center hole of the sealing ring 2. The inner ring surface of the sealing bearing 3 is arranged to contact the outer ring surface of the main shaft. A plurality of first screw holes are arranged on the inner wall surface of the annular mounting groove 12. The sealing ring 2 is provided with a fixing hole at a position corresponding to the first screw hole. The screws are threaded through the fixing hole and connected to the first screw hole.

[0028] Among them, the fan-shaped blocks are combined to form a main shaft. After the screw is unscrewed from the first screw hole, the sealing ring and the sealing bearing can be removed from the main shaft. At this time, the outer tube can be disassembled from the main shaft. After losing the outer tube, the fan-shaped blocks can be separated, so that they can be replaced independently, avoiding the waste caused by the entire replacement; and after separation, the interior of the fan-shaped blocks can be inspected to avoid cracks, so as to ensure the safety of equipment operation.

[0029] In this embodiment, arc-shaped limit blocks 13 are installed at both ends of the sector block 5, and multiple ball grooves are provided on the outer side of the limit block 13, and balls 14 are movably installed in the ball grooves. Parts of the balls 14 extend to the outside along the openings of the ball grooves and are arranged to contact the inner side of the seal.

[0030] The main shaft can be positioned axially by the limit block and the ball, and the friction between the seal and the limit block is reduced by the ball, so that the main shaft can rotate smoothly.

[0031] In this embodiment, positioning holes 17 and positioning columns are respectively provided on both sides of the sector block 5. The positioning columns are inserted into the positioning holes 17 of adjacent sector blocks 5. The sector blocks can be axially positioned by plugging the positioning columns and the positioning holes, thereby avoiding misalignment between the sector blocks.

[0032] In this embodiment, a plurality of cooling ports are provided on the upper shell 10, each of which is equipped with a refrigerator 11. The heat generating end of the refrigerator 11 faces outwards and is equipped with a plurality of heat dissipation blades.

[0033] In this embodiment, coolant is stored in the annular channel and the housing 10 below, a cylinder 7 is mounted on the push block 6 , a fixing frame 8 is mounted outside the cylinder 7 , and the other end of the fixing frame 8 is mounted on the housing 10 .

[0034] In this embodiment, a telescopic rod 9 is installed on one side of the shell 10, and a connecting flange is installed on the other end of the telescopic rod 9. The connecting flange can be installed on the equipment on one side to ensure the stability of the shell and the outer tube to avoid being driven by the main shaft.

[0035] In this embodiment, the length of the outer tube 1 is smaller than that of the main shaft, and both ends of the main shaft are exposed so that the two ends of the main shaft can be connected to the components between the driving mechanism and the synchronous wheel respectively.

[0036] In this embodiment, a second screw hole for connecting with the coupling is provided on one of the sector blocks 5. After the coupling is sleeved on the main shaft, the bolts on the coupling can be inserted into the second screw hole to ensure the installation stability of the coupling.

[0037] Among them, since the lower shell and the annular channel are provided with coolant, and the main shaft is composed of multiple fan-shaped blocks, the coolant in the annular channel can enter the cooling cavity along the cooling channel, and the coolant in the cooling cavity can cool the main shaft from the inside to the outside, and the coolant in the cooling channel can cool the inside of the outer wall of the main shaft, and the coolant in the annular channel can cool the outer ring surface of the main shaft, thereby increasing the comprehensiveness of cooling;

[0038] During the cooling process, the cylinder can be started to make the piston rod of the cylinder continuously extend and retract. The movement of the piston rod drives the push block and the piston. After the piston moves upward, the coolant can be pushed upward and contact with the refrigerator, thereby dissipating the heat in the coolant. After the push block drops, the coolant will drop, making the coolant in a flowing state, and continuously entering and exiting the cooling channel and contacting the refrigerator to ensure the cooling effect of the coolant itself.

[0039] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
