Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment manufacturing technology, and in particular relates to a device for punching internal protrusions on copper pipes for refrigeration equipment. Background Technology

[0002] The device for creating internal bumps on copper pipes for refrigeration equipment is a specialized device used to form bumps inside copper pipes. This device plays a crucial role in the manufacturing process of refrigeration equipment, ensuring that the structure and performance of the copper pipes meet specific requirements.

[0003] The presence of internal protrusions alters the flow path of the refrigerant within the copper tube, resulting in a more uniform and efficient flow, which helps improve refrigeration efficiency and allows the refrigeration equipment to reach the set temperature in a shorter time. Internal protrusions also increase the surface area of ​​the inner wall of the copper tube, thereby increasing the contact area between the refrigerant and the inner wall, which helps improve the heat exchange efficiency of the refrigerant, enabling the refrigeration equipment to absorb and release heat more effectively during operation. Furthermore, internal protrusions enhance the structural strength of the copper tube, making it more durable and reliable.

[0004] A search revealed that CN214813973U, published on November 23, 2021, discloses a copper tube double-protrusion forming device, belonging to the field of refrigeration equipment component manufacturing. It includes a frame, a dotting mechanism, and a clamping mechanism. The dotting mechanism has a spring with protrusions, and the spring has a channel through which a mandrel passes. The dotting mechanism controls the mandrel to extend forward within the channel, pressing the spring to both sides. The clamping mechanism clamps the copper tube fitted onto the spring, so that when the spring protrusions press to both sides, they can press from the inside of the copper tube against the sidewall towards the outside, forming protrusions. This invention can simultaneously create two protrusions on the sidewall of the copper tube, ensuring that the two protrusions are located on the same cross-section of the copper tube, so that when the copper tube is welded, the protrusions can be stably locked at the opening of the main pipe.

[0005] This patent has the following shortcomings:

[0006] 1. This bump forming device can simultaneously make two bumps on a copper tube, improving the bump forming efficiency and is easy to operate. However, it can only make two bumps at the same time. For some copper tubes that are long and require the inner wall of the copper tube to be covered with bumps, this bump forming efficiency is difficult to mass-produce.

[0007] 2. The adjustableness of this embossing device is poor, making it difficult to adapt to the use of copper tubes of different specifications, and the style of the embossing is also relatively simple.

[0008] To address this issue, we provide a device for punching internal protrusions in copper pipes for refrigeration equipment. Utility Model Content
