Description

Technical Field

[0001] This utility model relates to the field of finned tube forming and processing technology, specifically a cutting device for finned tube forming and processing. Background Technology

[0002] Finned tube forming refers to the process of adding fins to an existing tube using specific techniques, thereby significantly increasing the heat exchange area and improving heat exchange efficiency. Finned tubes are also known as finned tubes or ribbed tubes, and are a type of tube with an expanded surface. The finned tube forming process requires a cutting device to cut the finned tube.

[0003] According to a Chinese patent publication CN219818995U, a cutting device for finned tube forming and processing includes a base, a processing box installed at the top center of the base, a grid plate connected to the top of the processing box, a door installed on the front surface of the processing box, a communicating structure in the inner cavity of the processing box, a purification plate distributed on the inner side of the communicating structure, and a honeycomb adsorption plate distributed below the purification plate. By combining the fan, the purification plate, and the honeycomb adsorption plate, the waste gas or dust generated during finned tube cutting can be effectively absorbed and purified, thereby preventing the waste gas and dust from polluting the surrounding environment. Since the internal structure of the purification plate is made of activated carbon, combined with the honeycomb adsorption plate supported by bamboo charcoal, dust can be effectively adsorbed and purified. The air force generated by the fan during operation can draw the waste gas generated during cutting into the interior of the processing box for treatment.

[0004] The existing device uses an upper clamp to effectively limit the two ends of the finned tube. However, it has the following problems: when cutting the lower surface of the finned tube, the tube needs to be manually rotated, which wastes a lot of time and reduces the cutting efficiency of the finned tube forming process. Therefore, a cutting device for finned tube forming is proposed. Utility Model Content

The rotating rod 501 and the double-threaded rod 502 are rotatably connected to the inner wall of the slot via bearing seats. Through the clamping assembly 50, the double-threaded rod 502 drives the two sliders 504 to move closer to each other, so that the upper clamping plate 508 and the lower clamping plate 509 clamp and fix finned tubes of different lengths.

[0040] Example 2: Based on Example 1, a preferred embodiment of the cutting device for finned tube forming and processing provided by this utility model is as follows: Figure 1 - Figure 3 and Figure 5As shown: The cutting assembly 51 includes a second electric push rod 513 fixedly connected to the top surface of the adjusting plate 4.

[0042] In use, the finned tube is placed between the upper clamping plate 508 and the lower clamping plate 509. Rotating the rotating plate 5011 causes the rotating rod 501 to drive the connected bevel gear 503 to rotate. Through the meshing transmission of the two bevel gears 503, the double-threaded rod 502 rotates, causing the two sliders 504 to move closer to each other. This causes the upper clamping plate 508 and the lower clamping plate 509 to move closer to each other, clamping and fixing the finned tube. The limiting rod 5012 is inserted into the through hole and the limiting hole to limit the rotation plate 5011. When it is necessary to cut the left side surface of the finned tube, the motor 507 is turned on. The output rod of the motor 507 drives the upper clamping plate 508 to rotate, causing the finned tube to rotate, thereby cutting the left side surface of the finned tube.

[0043] The first electric push rod 511 is activated, and the output rod of the first electric push rod 511 drives the connected adjusting plate 4 to move inside the slide groove, so that the cutting machine 515 is close to the finned tube; the second electric push rod 513 is activated, and the second electric push rod 513 drives the moving block to rise and fall, so that the moving block 513 drives the cutting machine 515 to rise and fall, thereby cutting different positions on the surface of the finned tube.
