[0038] It should be noted that, where there is no conflict, different features in the embodiments of this utility model can be combined with each other.
[0039] In view of this, this embodiment provides a solution that can solve the above problems. The specific implementation of this utility model will be described in detail below with reference to the accompanying drawings.
[0040] Please refer to Figure 1 , Figure 1 Example: A possible structural schematic diagram of the refrigeration equipment pipe bending device provided in this embodiment. The refrigeration equipment pipe bending device may include a connector 300 and a first limiting member 100 and a second limiting member 200 arranged sequentially along the extension direction of the pipe 400 to be bent.
[0041] The first limiting member 100 and the second limiting member 200 can be connected to the connecting member 300 respectively. The first limiting member 100 and the second limiting member 200 can be located on the same side of the connecting member 300. The first limiting member 100 and the second limiting member 200 can be used to limit the pipe 400 to be bent during the bending process.
[0042] In this embodiment, the first end of the pipe 400 to be bent can be located inside the compressor compartment of the refrigeration equipment, and the second end of the pipe 400 to be bent can be connected to another pipe after bending. The first limiting member 100 can be located near the first end of the pipe 400 to be bent, and the second limiting member 200 can be located near the second end of the pipe 400 to be bent. The pipe 400 to be bent can pass through the area between the first limiting member 100 and the second limiting member 200, ensuring close contact between the pipe 400 to be bent and the first limiting member 100 and the second limiting member 200. The first limiting member 100 can be used to limit the position of one end of the bending arc of the pipe 400 to be bent, and the second limiting member 200 can be used to limit the position of the other end of the bending arc of the pipe 400 to be bent. The materials of the first limiting member 100, the second limiting member 200, and the connecting member 300 can be metallic materials, such as steel or aluminum.
[0043] It should be noted that the materials of the first limiting member 100, the second limiting member 200 and the connecting member 300 are not limited to metal materials. The materials of the first limiting member 100, the second limiting member 200 and the connecting member 300 can also be plastic, as long as the materials of the first limiting member 100, the second limiting member 200 and the connecting member 300 have high rigidity. No specific limitation is made here.
[0044] Specifically, the pipe 400 to be bent can be simultaneously located below the first limiting member 100 and above the second limiting member 200. When bending the pipe 400, the connector 300 can be rotated clockwise according to the required bending angle, thereby driving the condenser pipe to bend to the specified angle.
[0045] The 400mm bendable pipe refers to the anti-condensation pipe used in refrigeration equipment to prevent condensation. It is typically made of copper and connects to the condenser. During the refrigeration process, high-pressure gaseous refrigerant flows through the anti-condensation pipe, releasing heat. The heat transfer capacity of the anti-condensation pipe prevents water droplets from forming, thus achieving a good anti-condensation effect. Specifically, anti-condensation pipes can include anti-condensation pipes on the central beam of the cabinet, anti-condensation pipes on the side of the cabinet shell, and anti-condensation pipes on the rear.
[0046] Furthermore, the refrigeration equipment in this embodiment can be a stand-alone refrigeration device or a combined refrigeration device consisting of multiple mutually separated refrigeration compartments that achieve simultaneous refrigeration. For example, the refrigeration equipment can be a refrigerator, freezer, etc.
[0047] As can be seen, based on the above design, the refrigeration equipment pipe bending device provided in this embodiment limits the pipe 400 to be bent by the first limiting member 100 and the second limiting member 200, and achieves bending of the pipe 400 by rotating the connecting member 300. This ensures that the bent pipe will not form a sharp corner and that the bend curvature is consistent, thereby improving product quality and the aesthetics of the piping. In addition, compared with manual bending, the refrigeration equipment pipe bending device provided in this embodiment is more time-saving and labor-saving, improves production efficiency, and reduces labor costs.
[0048] In one possible implementation, please refer to Figure 2 The first limiting member is provided with a first limiting groove 110. The second limiting member is provided with a second limiting groove 210. The first limiting groove 110 can be arranged opposite to the second limiting groove 210; the extension direction of the first limiting groove 110 and the second limiting groove 210 can be parallel to the extension direction of the pipe 400 to be bent.
[0049] In this embodiment, the extension direction of the first limiting groove 110 can be perpendicular to the extension direction of the first limiting member 100, and the extension direction of the second limiting groove 210 can be perpendicular to the extension direction of the second limiting member 200. The straight line containing the extension direction of the first limiting groove 110 can coincide with the straight line containing the extension direction of the second limiting groove 210. During the bending process of the pipe 400 to be bent, the first limiting groove 110 and the second limiting groove 210 can be used to limit the position of the pipe 400 to be bent, preventing the position of the pipe 400 to be bent from shifting. The extension directions of the first limiting groove 110 and the second limiting groove 210 are parallel to the extension direction of the pipe 400 to be bent, so that the pipe 400 to be bent can be stably embedded in the first limiting groove 110 and the second limiting groove 210 before bending.
[0050] Specifically, the pipe 400 to be bent can be embedded in the first limiting groove 110 and the second limiting groove 210. The groove walls of the first limiting groove 110 and the second limiting groove 210 can restrict the lateral movement of the pipe 400 to be bent, ensuring that the bending point is accurately positioned.
[0051] During the bending process of the pipe 400, it can first be placed into the first limiting groove 110 and the second limiting groove 210. The first limiting groove 110 and the second limiting groove 210 cooperate with each other to restrict the movement of the pipe 400 during the bending process. Then, the connector 300 can be rotated clockwise according to the required bending angle to make the pipe 400 bend smoothly to form the required angles such as 90° and 180°.
[0052] Furthermore, the distance between the edge of the second limiting groove 210 and the second end of the pipe 400 to be bent can range from 15 mm to 25 mm. For example, the distance between the edge of the second limiting groove 210 and the second end of the pipe 400 to be bent can include 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 22 mm, 23 mm, 24 mm, and 25 mm, etc. Preferably, the distance between the edge of the second limiting groove 210 and the second end of the pipe 400 to be bent can be 20 mm.
[0053] It should be noted that the number of the first limiting groove 110 and the second limiting groove 210 is not limited to one, but can be multiple. The specific number can be adjusted according to different bending requirements, and no specific limit is made here.
[0054] In some examples, please refer to Figure 3 For multiple pipes 400 of different diameters to be bent, multiple first limiting grooves 110 and second limiting grooves 210 of different widths can be set to reduce the time for replacing the pipe bending device of the refrigeration equipment, reduce time costs, and the pipe bending device of the refrigeration equipment can be used to bend multiple pipes 400 of different diameters at the same time.
[0055] In other examples, please refer to Figure 4 To meet different bending angle requirements, multiple first limiting grooves 110 and second limiting grooves 210 with different depths can be set to precisely control the bending arc. For example, for small-angle bends (such as 30° to 60°), the depths of the first limiting groove 110 and second limiting groove 210 can be set to be smaller; for large-angle bends (such as 90° to 180°), the depths of the first limiting groove 110 and second limiting groove 210 can be set to be larger.
[0056] In the above structure, by setting a first limiting groove 110 on the first limiting member and a second limiting groove 210 on the second limiting member, the positioning of the pipe 400 to be bent can be facilitated, the offset of the pipe 400 to be bent can be reduced, and the pipe 400 to be bent can be guaranteed not to be deformed by external pressure during the bending process.
[0057] In one possible implementation, please refer to Figure 5 The width W1 of the first limiting groove 110 and the second limiting groove 210 can be greater than the diameter W2 of the pipe 400 to be bent. Preferably, the width W1 of the first limiting groove 110 and the second limiting groove 210 can be in the range of 6 mm to 8 mm.
[0058] In this embodiment, the widths W1 of the first limiting groove 110 and the second limiting groove 210 are equal, and the widths W1 of the first limiting groove 110 and the second limiting groove 210 can be greater than the diameter W2 of the pipe 400 to be bent. In this way, it is convenient to put the pipe 400 to be bent into the first limiting groove 110 and the second limiting groove 210.
[0059] For example, the width W1 of the first limiting groove 110 and the second limiting groove 210 may include 6 mm, 6.1 mm, 6.4 mm, 6.5 mm, 6.7 mm, 7 mm, 7.2 mm, 7.7 mm, 7.9 mm, and 8 mm, etc. The appropriate width W1 of the first limiting groove 110 and the second limiting groove 210 can be selected according to specific circumstances.
[0060] In one possible implementation, the shape of the first limiting groove 110 and the second limiting groove 210 may include a semi-circle, and the diameter of the first limiting groove 110 and the second limiting groove 210 may range from 6 mm to 10 mm.
[0061] In this embodiment, the shapes of the first limiting groove 110 and the second limiting groove 210 can be semi-circular in the extending direction of the first limiting groove 110 and the second limiting groove 210. For example, the diameter of the semi-circle can include 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.4 mm, 9.8 mm, and 10 mm, etc. Appropriate diameters of the first limiting groove 110 and the second limiting groove 210 can be selected according to specific circumstances.
[0062] It should be noted that the cross-sectional shape of the first limiting groove 110 and the second limiting groove 210 can be adjusted according to actual needs. For example, the cross-sectional shape of the first limiting groove 110 and the second limiting groove 210 can be U-shaped, V-shaped, square, etc., and no specific limitation is made here.
[0063] In one possible implementation, at least a portion of the surfaces of the first limiting groove 110 and the second limiting groove 210 are provided with a protective layer, the material of which may include a flexible material.
[0064] In this embodiment, a protective layer can be covered on the surface (such as the bottom or side wall) of the first limiting groove 110 and the second limiting groove 210. This protective layer can directly contact the pipe 400 to be bent, thereby reducing the friction between the first limiting groove 110 and the second limiting groove 210 and the pipe 400 to be bent, and preventing damage to the pipe 400 to be bent.
[0065] Specifically, the protective layer can be located only on the surfaces of the first limiting groove 110 and the second limiting groove 210 that contact the pipe 400 to be bent, in order to reduce costs. Alternatively, the protective layer can completely cover all surfaces of the first limiting groove 110 and the second limiting groove 210 to provide comprehensive protection suitable for high-precision bending.
[0066] In addition, the material of this protective layer can be a flexible material, such as rubber, polyurethane, silicone, etc., which can be selected according to actual needs.
[0067] The thickness of the protective layer can range from 0.5 mm to 2 mm. This avoids insufficient cushioning due to too small a thickness, and also avoids affecting bending accuracy due to too large a thickness.
[0068] To reduce friction between the first limiting groove 110 and the second limiting groove 210 and the pipe 400 to be bent, a rolling structure can be provided in the first limiting groove 110 and the second limiting groove 210 to form rolling friction with the contact surface of the pipe 400 to be bent. Specifically, the rolling structure can be provided on the bottom surface or side wall of the first limiting groove 110 and the second limiting groove 210 to protect the surface of the pipe 400 to be bent.
[0069] For example, the rolling structure can be a roller.
[0070] In one possible implementation, please refer again. Figure 1 The first limiting member 100 and the second limiting member 200 may be cylindrical in shape. The length L1 of the first limiting member 100 and the second limiting member 200 may range from 100 mm to 150 mm, and the diameter L2 of the first limiting member 100 and the second limiting member 200 may range from 20 mm to 40 mm.
[0071] In this embodiment, the first limiting member 100 and the second limiting member 200 may have the same shape. The first limiting member 100 and the second limiting member 200 may both be cylindrical. The first limiting member 100 and the second limiting member 200 may extend in the same direction. The extension direction of the first limiting member 100 and the second limiting member 200 may be perpendicular to the extension direction of the pipe 400 to be bent.
[0072] The length L1 of the first limiting member 100 and the second limiting member 200 can be the same. For example, the length L1 of the first limiting member 100 and the second limiting member 200 can include 100 mm, 105 mm, 110 mm, 112 mm, 118 mm, 120 mm, 125 mm, 130 mm, 140 mm, and 150 mm, etc. The appropriate length L1 of the first limiting member 100 and the second limiting member 200 can be selected according to the specific situation.
[0073] The diameter L2 of the first limiting member 100 and the second limiting member 200 can be the same. For example, the diameter L2 of the first limiting member 100 and the second limiting member 200 can include 20 mm, 21 mm, 25 mm, 26 mm, 28 mm, 29 mm, 30 mm, 32 mm, 38 mm, and 40 mm, etc. The appropriate diameter L2 of the first limiting member 100 and the second limiting member 200 can be selected according to the specific situation.
[0074] In one possible implementation, please refer again. Figure 1 The first limiting member 100 and the second limiting member 200 can be arranged in parallel. The distance L3 between the first limiting member 100 and the second limiting member 200 can range from 80 mm to 110 mm.
[0075] In this embodiment, the first limiting member 100 and the second limiting member 200 are parallel to each other, and the extension directions of the first limiting member 100 and the second limiting member 200 can both be perpendicular to the extension direction of the pipe 400 to be bent. For example, the distance L3 between the first limiting member 100 and the second limiting member 200 can be 80 mm, 81 mm, 85 mm, 88 mm, 90 mm, 95 mm, 100 mm, 104 mm, 105 mm, and 110 mm, etc. A suitable distance L3 between the first limiting member 100 and the second limiting member 200 can be selected according to specific circumstances.
[0076] In the above structure, by setting the distance L3 between the first limiting member 100 and the second limiting member 200 to be between 80 mm and 110 mm, it is possible not only to ensure that the pipe 400 to be bent can be accurately connected with another short pipe after bending, but also to make the rotation process more labor-saving.
[0077] In one possible implementation, please refer to Figure 6The connector 300 may include a first connecting shaft 310, a second connecting shaft 320, and a third connecting shaft 330. The first connecting shaft 310 and the second connecting shaft 320 may be arranged in parallel, and the third connecting shaft 330 may be connected between the first connecting shaft 310 and the second connecting shaft 320.
[0078] In this embodiment, the length of the first connecting shaft 310 can be less than the length of the second connecting shaft 320, the third connecting shaft 330 can be perpendicular to the first connecting shaft 310 and the second connecting shaft 320, and one end of the third connecting shaft 330 is connected to the middle position of the first connecting shaft 310, and the other end of the third connecting shaft 330 is connected to the middle position of the second connecting shaft 320.
[0079] The first connecting shaft 310, the second connecting shaft 320, and the third connecting shaft 330 can be cylindrical in shape, and their diameters can be equal.
[0080] In one possible implementation, the first limiting member 100 and the second limiting member 200 can be connected to the two ends of the first connecting shaft 310, respectively. The first limiting member 100 and the second limiting member 200 can be symmetrically arranged relative to the third connecting shaft 330.
[0081] In this embodiment, the third connecting shaft 330 can be connected to the middle position of the first connecting shaft 310, and the first limiting member 100 and the second limiting member 200 can be symmetrically arranged relative to the third connecting shaft 330. The length of the first connecting shaft 310 can be equal to the distance between the first limiting member 100 and the second limiting member 200, that is, the length of the first connecting shaft 310 can be in the range of 80 mm to 110 mm.
[0082] During the bending process of the pipe 400, the pipe 400 can be passed through the area between the first limiting member 100 and the second limiting member 200, so that the pipe 400 is below the first limiting member 100 and above the second limiting member 200. Then, the third connecting shaft 330 is held and rotated clockwise, which drives the first limiting member 100 and the second limiting member 200 to rotate synchronously, so that the pipe 400 is bent to form the desired angle such as 90° or 180°.
[0083] In one possible implementation, the first limiting member 100 and the second limiting member 200 can be detachably connected to the first connecting shaft 310, respectively.
[0084] In this embodiment, the first limiting member 100 and the second limiting member 200 can be connected to the first connecting shaft 310 by threads. For example, the two ends of the first connecting shaft 310 can be provided with external threads, and the first limiting member 100 and the second limiting member 200 are provided with corresponding threaded holes. In this way, the first limiting member 100 and the second limiting member 200 can be detachably connected to the first connecting shaft 310.
[0085] It should be noted that the connection method between the first limiting member 100 and the second limiting member 200 and the first connecting shaft 310 is not limited to threads, but can also be a pin, a snap fastener, etc., which are not specifically limited here.
[0086] In the above structure, by setting the first limiting member 100 and the second limiting member 200 to be detachably connected to the first connecting shaft 310, the first limiting member 100 and the second limiting member 200 can be quickly replaced to adapt to different pipe diameters or bending angles. Furthermore, the wear condition of the first limiting member 100 and the second limiting member 200 can be checked periodically. When the first limiting member 100 and the second limiting member 200 are worn, there is no need to replace the entire structure, which can reduce costs.
[0087] Please refer to Figure 7a and Figure 7b Based on the above design, the working principle of the refrigeration equipment pipe bending device provided in this embodiment is as follows:
[0088] During the production process of the refrigeration equipment, the pipe 400 to be bent is pulled out of the compressor chamber and simultaneously placed into the first limiting groove 110 of the first limiting member 100 and the second limiting groove 210 of the second limiting member 200, so that the pipe 400 to be bent is below the first limiting member 100 and above the second limiting member 200. Then, the third connecting shaft 330 is held and rotated clockwise, which drives the first limiting member 100 and the second limiting member 200 to rotate synchronously, so that the pipe 400 to be bent is bent until the required angle is formed. Finally, the free end of the bent pipe is connected to the free end of another short pipe.
[0089] In summary, this embodiment provides a pipe bending device for refrigeration equipment. By using a first and second limiting member to limit the pipe to be bent, and by rotating the connecting member, the pipe is bent. This ensures that the bent pipe will not form a sharp corner and that the bend radius is consistent, thereby improving product quality and the aesthetics of the piping. Furthermore, compared to manual bending, the pipe bending device for refrigeration equipment provided in this embodiment is more time-saving and labor-saving, improving production efficiency and reducing labor costs.
[0090] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
