[0027] After the processed bolts are installed by the limit assembly, it is now necessary to adjust the distance between the two rolling rollers 17. The rocker 20 is rotated by hand, and the two-way screw rod 18 is driven to rotate inside the sleeve block 22 by the manual rocker 20, so that the two sleeve blocks 22 are close to the outer surface of the bolt inside the slide groove 26.

Now the water enters the connecting pipe 27 through the water tank 14. Now turn on the motor 2 30, and the motor 2 30 drives the rotating shaft 36 to rotate. The rotating shaft 36 drives the cam 32 to rotate inside the box 16. The cam 32 squeezes the moving block 33, and the moving block 33 is pressed by the moving block 33, so that the moving block 33 is in contact with the connecting pipe 27. 7 and the interior of the connecting pipe 2 35 do not overlap, so that water cannot pass through the connecting pipe 1 27 to the interior of the moving block 33. When the cam 32 does not squeeze the moving block 33, so that the moving block 33 overlaps with the connecting pipe 1 27 and the connecting pipe 2 35, the water is poured into the interior of the moving block 33 and the connecting pipe 2 35 through the connecting pipe 1 27, and then enters the interior of the box body 2 31 through the connecting pipe 2 35, and then enters the interior of the drip pipe 29 through the box body 2 31, so that the water slowly drips onto the outer surface of the bolt through the drip pipe 29, thereby completing the cooling of the bolt.

At the same time, indirect cooling can also reduce the temperature of the equipment, reduce the possibility of failure, reduce maintenance costs, and ensure the safety and health of the operator. By reducing the thermal stress caused by temperature changes, indirect cooling can also improve the stability and reliability of the equipment, help maintain the overall performance of the equipment, and further extend the service life of the equipment.

[0033] By placing the bolts that need to be processed on the bracket 8, and then opening the inside of the electric push rod 7 on the inner side of the vertical plate 6, the electric push rod 7 pushes the bolts to move inside the bracket 8, and then the bolts squeeze the moving column 24, so that the moving column 24 squeezes the spring 1 25 inside the vertical plate 2 19, thereby completing the installation of the bolts, facilitating the installation of the bolts that need to be processed between the electric push rod 7 and the moving column 24, and improving the installation efficiency of the bolts.

[0035] By holding the tool box 5, the limit block 4 is driven by the tool box 5 to slowly enter the interior of the limit hole 23, and the limit block 4 is limited by the limit hole 23. By adding the tool box 5, it is convenient for the staff to take and place the maintenance tools inside the tool box 5, thereby improving the maintenance efficiency of the thread rolling machine.
[0036] Among them, a support plate 2 is fixedly installed at the bottom of the workbench 1, and a connecting plate 10 is fixedly installed between the two support plates 2.

[0040] A second connecting plate 28 is fixedly installed inside the second supporting plate 13 , and the second connecting plate 28 presents two shapes of the same size.
[0041] Since the second connecting plate 28 presents two shapes of the same size inside the second supporting plate 13, it is convenient to support the second supporting plate 13. The second supporting plate 13 supports the water tank 14, reducing the shaking of the water tank 14 during use and improving the use efficiency of the water tank 14.
[0042] The support base 12 is fixedly mounted on the right side of the movable frame 21 , and the interior of the support base 12 is U-shaped.
[0043] Since the interior of the support base 12 is shaped to the right of the mobile frame 21, it is convenient to provide stable support for the motor 11, reduce the shaking of the motor 11 during use, and ensure the stability of the motor 11 during use.

[0048] The working principle and use process of this utility model:
[0049] After the staff has completed the installation of the processed bolts through the limit assembly, it is now necessary to adjust the distance between the two rolling rollers 17. By manually rotating the rocker 20, the manual rocker 20 drives the bidirectional screw 18 to rotate inside the sleeve block 22, so that the two sleeve blocks 22 are close to the outer surface of the bolt inside the slide groove 26, and the sleeve block 22 drives the moving frame 21 to move synchronously, and the moving frame 21 drives the rolling roller 17 to move slowly. Now turn on the motor 11, and the motor 11 drives the rolling roller 17 to rotate. By processing the two pairs of bolts, the distance between the two rolling rollers 17 is adjusted.
[0050] During the bolt processing, the staff needs to cool the bolts. First, insert the water pipe into the water inlet 15, and then pour water into the water tank 14.

The rotating shaft 36 drives the cam 32 to rotate inside the box 16. The cam 32 squeezes the moving block 33, and the moving block 33 is pressed by the moving block 33, so that the moving block 33 is in contact with the connecting pipe 27. 7 and the interior of the connecting pipe 2 35 do not overlap, so that water cannot pass through the connecting pipe 1 27 to the interior of the moving block 33. When the cam 32 does not squeeze the moving block 33, so that the moving block 33 overlaps with the connecting pipe 1 27 and the connecting pipe 2 35, the water is poured into the interior of the moving block 33 and the connecting pipe 2 35 through the connecting pipe 1 27, and then enters the interior of the box body 2 31 through the connecting pipe 2 35, and then enters the interior of the drip pipe 29 through the box body 2 31, so that the water slowly drips onto the outer surface of the bolt through the drip pipe 29, thereby completing the cooling of the bolt.
