Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, specifically to a pipe cooling device for uniform cooling. Background Technology

[0002] Modern pipe manufacturing technology emphasizes high-precision manufacturing. Through advanced production equipment and technical means, it ensures that the dimensional accuracy, shape accuracy and surface quality of the pipes reach extremely high standards. Generally, rubber pipes are produced using a hot-drawing process, and the pipes need to be cooled and shaped after forming.

[0003] Chinese patent CN219618465U discloses a pipe cooling device, including a cooling chamber, a spray cooling mechanism, and a water removal mechanism. In actual production, when pipe cooling is required, the pipe is formed and enters the cooling chamber through the inlet. The spray cooling mechanism then sprays cooling water onto the pipe, cooling it. The cooled pipe is then output to a collection tank through the outlet. The pipe then passes through a scraper assembly, which scrapes off water droplets adhering to its outer surface. These droplets fall into the collection tank for collection. The scraped pipe is then output to the outside of the device for the next process. However, this device still has the following problems during use:

[0004] The spray cooling mechanism of this device is fixedly installed on the top of the cooling chamber. When the spray mechanism is working, the sprayed liquid falls on the upper end of the pipe, which may cause the amount of water flowing down the upper end of the pipe to be different, thus reducing the cooling effect.

[0005] Based on this, the present invention designs a pipe cooling device for uniform cooling to solve the above problems. Utility Model Content

[0044] The centering clamping assembly 42 includes a rotating disk 421, a limiting block 422, a sliding groove 423, a sliding rod 424, and a roller 425.

Multiple limiting blocks 422 are rotatably connected to the outer edge of the middle part of the rotating disk 421, and the limiting blocks 422 are evenly distributed in a circle at equal intervals along the outer edge of the middle part of the rotating disk 421.

The roller 425 is in contact with the pipe 2.

[0045] The first drive assembly 41 includes a servo motor 411, a support plate 412, a lead screw 413, a first rotating block 414, and a second rotating block 415. The support plate 412 is symmetrically and rotatably mounted on the left and right ends of the cooling box 1. The servo motor 411 is fixedly mounted on the outer end of the support plate 412, and the output end of the servo motor 411 is fixedly connected to the lead screw 413. The first rotating block 414 is rotatably connected to the outer end of the cooling box 1. The second rotating block 415 is rotatably connected to the upper end of the rotating disk 421.

[0046] In this invention, when the diameter of the pipe 2 requiring cooling is small, the servo motor 411 is activated.

During the leftward movement of the second rotating block 415, the rotating disk 421 is driven to rotate, and the first rotating block 414 rotates, causing the lead screw 413 to rotate as well. This allows the second rotating block 415 to continue to maintain contact with the lead screw 413 while the rotating disk 421 rotates. The rotation of the rotating disk 421 drives the limiting block 422 to rotate as well, causing the three sliding rods 424 to slide along the sliding groove 423 and rotate towards the center of the pipe 2. The rollers 425 rotate with the sliding rods 424, thereby changing the spatial position of the three rollers 425. This allows the rollers 425 to support the pipe 2 with a small diameter and facilitates the conveying device to transport the pipe.

[0047] When pipe 2 delivers the coolant to the middle of cooling box 1, motor 312 is started. Motor 312 drives crank 313 to rotate. As crank 313 rotates, it slides up and down in slide groove 315, thereby driving rack 316 to move horizontally along guide rod 317 along sliding plate 314. The movement of rack 316 drives half gear ring 324 to drive rotating ring 321 to rotate. The rotation of rotating ring 321 allows horizontal plate 323 to rotate along rotating groove 322 along with rotating ring 321, realizing the back-and-forth swing of nozzle 5, thereby achieving a more uniform spray cooling effect on pipe 2.
