[0030] Referring to Figure 1 and Figure 2 The rolling roller 10 is used in the heat exchange plate surface precision texture forming device 100, and the rolling roller 10 comprises a shaft body 12 and a roller 14. The roller 14 is detachably sleeved on the shaft body 12, and the surface of the roller 14 away from the shaft body 12 has a texture.

[0031] The roller 14 with the texture is detachably sleeved on the shaft body 12. After the rolling roller 10 is installed in the heat exchange plate surface precision texture forming device 100, a plurality of rollers 14 can be configured by only one set of forming device 100, and different textures can be realized by replacing the roller 14. Therefore, the utilization rate of the heat exchange plate surface precision texture forming device 100 can be improved, and the production cost can be reduced.

[0032] Specifically, the rolling roller 10 is a main working component and tool for continuously plastic deformation of metal on a rolling processing equipment. The outer peripheral surface of the rolling roller 10 is provided with a texture. After the workpiece to be processed contacts the rolling roller 10, the surface of the workpiece to be processed will form a texture corresponding to the texture of the surface of the rolling roller 10. Therefore, the surface texture of the workpiece to be processed can be processed.

[0033] The roller 14 with the surface texture of the rolling roller 10 is separated from the shaft body 12. When processing, the roller 14 is installed on the shaft body 12, so that the shaft body 12 can be driven. When different textures need to be processed, the roller 14 with different textures can be directly replaced, without the need for overall processing of the rolling roller 10. Therefore, the processing material can be saved, and the processing difficulty can be reduced.

[0034] In addition, in the processing and production process, the rolling roller 10 is a consumable part. When the surface texture of the roller 14 is worn, only the roller 14 can be replaced, so that the processing cost can be reduced.

[0035] In some embodiments, the shaft body 12 comprises a first stepped portion 16 and a second stepped portion 18. The first stepped portion 16 is connected to the second stepped portion 18, and the roller 14 is sleeved on the second stepped portion 18. The stepped surface 17 of the first stepped portion 16 abuts against the wall surface on one side of the roller 14, so as to limit the displacement of the roller 14 in the axial direction of the shaft body 12.

[0036] In this way, the displacement of the roller 14 in the axial direction of the shaft body 12 is limited by the stepped surface 17 of the first stepped portion 16, so that the movement of the roller 14 on the shaft body 12 can be avoided.

[0037] Specifically, the shaft body 12 includes a first stepped portion 16 and a second stepped portion 18, the first stepped portion 16 forms a stepped surface 17 at the connection with the second stepped portion 18, and when the roller barrel 14 is sleeved on the second stepped portion 18, the wall surface on one side of the roller barrel 14 abuts against the stepped surface 17 of the first stepped portion 16, so that the displacement of the roller barrel 14 in the axial direction of the shaft body 12 can be limited, as shown in Figure 2 The axial direction of the shaft body 12 is the left-right direction in the figure.

[0038] The other side of the roller barrel 14 can be fixed by the support 30 of the forming device 100 to limit the displacement of the other side wall surface of the roller barrel 14 in the axial direction, so as to avoid the movement of the roller barrel 14 affecting the subsequent processing of the workpiece by the roller 10.

[0039] Further, the shaft body 12 further includes a third stepped portion 24 and a fixing nut 28, the third stepped portion 24 is connected to the second stepped portion 18, the third stepped portion 24 is provided with a thread, and when the roller barrel 14 is sleeved on the second stepped portion 18, the wall surface on one side of the roller barrel 14 abuts against the stepped surface 17 of the first stepped portion 16, and the fixing nut 28 is sleeved and locked on the third stepped portion 24, so that the fixing nut 28 abuts against the wall surface on the other side of the roller barrel 14, thereby limiting the displacement of the roller barrel 14 in the axial direction.

[0040] Please refer to Figure 2 In some embodiments, the outer circumferential surface of the second stepped portion 18 is provided with one of a positioning groove 20 and a positioning portion 22, and the inner wall surface of the roller barrel 14 is provided with the other one of the positioning groove 20 and the positioning portion 22, and the positioning groove 20 and the positioning portion 22 cooperate to limit the circumferential displacement between the shaft body 12 and the roller barrel 14.

[0041] In this way, the circumferential displacement between the shaft body 12 and the roller barrel 14 can be limited by the cooperation of the positioning groove 20 and the positioning portion 22.

[0042] Specifically, the roller barrel 14 is sleeved on the shaft body 12, and needs to be driven to rotate by the shaft body 12 to process continuous textures on the surface of the workpiece to be processed. Therefore, in the structure of the roller 10 designed to separate the roller barrel 14 from the shaft body 12, it is necessary to ensure that there is no relative rotation between the roller barrel 14 and the shaft body 12, so as to avoid the situation that the shaft body 12 cannot drive the roller barrel 14 to rotate.

[0043] In one embodiment, the outer circumferential surface of the second stepped portion 18 is provided with a positioning groove 20 with the same length as the second stepped portion 18, and the inner wall surface of the roller barrel 14 is provided with a positioning portion 22, and when the roller barrel 14 is sleeved on the second stepped portion 18, the positioning portion 22 is inserted into the positioning groove 20, thereby limiting the circumferential displacement between the shaft body 12 and the roller barrel 14.

[0044] Please refer toFigure 2 In some embodiments, the shaft body 12 comprises a third stepped portion 24, the second stepped portion 18 is connected to the third stepped portion 24, the roll 10 further comprises a length compensation sleeve 26, the length compensation sleeve 26 is sleeved on the third stepped portion 24, the roll barrel 14 is clamped between the first stepped portion 16 and the length compensation sleeve 26, and the first stepped portion 16 and the length compensation sleeve 26 cooperate to limit the displacement of the roll barrel 14 in the axial direction of the shaft body 12.

[0045] In this way, the length of the roll barrel 14 mounted on the roll 10 can be adjusted.

[0046] Specifically, the shaft body 12 comprises the first stepped portion 16, the second stepped portion 18 and the third stepped portion 24 connected in sequence, the roll barrel 14 is sleeved on the second stepped portion 18, the stepped surface 17 formed by the connection of the first stepped portion 16 and the second stepped portion 18 abuts against one side wall surface of the roll barrel 14, and the length compensation sleeve 26 is sleeved on the third stepped portion 24 and abuts against the other side wall surface of the roll barrel 14, so that the first stepped portion 16 and the length compensation sleeve 26 cooperate to limit the displacement of the roll barrel 14 in the axial direction of the shaft body 12.

[0047] Meanwhile, the length of the roll barrel 14 can be changed according to the processing needs, and the length of the roll barrel 14 can be the same as the length of the second stepped portion 18, or the length of the roll barrel 14 can be greater than the length of the second stepped portion 18. The length of the length compensation sleeve 26 cooperates with the length of the roll barrel 14, and the length of the length compensation sleeve 26 and the length of the roll barrel 14 are equal to the lengths of the second stepped portion 18 and the third stepped portion 24. When the roll 10 is mounted to the support 30 of the forming device 100, the first stepped portion 16 and the length compensation sleeve 26 can cooperate to limit the displacement of the roll barrel 14 in the axial direction of the shaft body 12.

[0048] In one embodiment, the third stepped portion 24 has a thread, the roll 10 further comprises a fixing nut 28, the roll barrel 14 is sleeved on the second stepped portion 18, the length compensation sleeve 26 is sleeved on the third stepped portion 24 and abuts against the roll barrel 14, and the fixing nut 28 is sleeved and tightened on the third stepped portion 24, so that the position of the length compensation sleeve 26 on the third stepped portion 24 is fixed, and the first stepped portion 16 and the length compensation sleeve 26 can cooperate to limit the displacement of the roll barrel 14 in the axial direction of the shaft body 12.

[0049] In one embodiment, the inner surface of the length compensation sleeve 26 can be provided with a thread, and the third stepped portion 24 has a corresponding thread. The length compensation sleeve 26 is sleeved and tightened on the third stepped portion 24, so that the length compensation sleeve 26 has both the length compensation effect and the fixing and limiting effect on the roll barrel 14.

[0050] In some embodiments, the texturing process of the outer surface of the roller 14 includes an etching process or an additive manufacturing process.

[0051] In this way, the roller 14 can be more economical and the processing cost can be reduced.

[0052] Specifically, additive manufacturing is a manufacturing technology that adds materials layer by layer to manufacture three-dimensional objects. It is based on a digital model file, and through software and a numerical control system, special metal materials, non-metal materials, and medical biological materials are stacked layer by layer in a manner of extrusion, sintering, melting, light curing, spraying, etc. to finally manufacture a solid object.

[0053] Using the additive manufacturing process can manufacture a complex and fine surface texture of the roller 14, and the additive manufacturing reduces material waste and processing time during manufacturing, which can improve manufacturing efficiency.

[0054] The texturing process of the outer surface of the roller 14 using additive manufacturing includes one or more of chemical vapor deposition, physical vapor deposition, atomic layer deposition, sputtering, evaporation, electroplating, and chemical plating.

[0055] Etching is a technique that removes part of the material using chemical reactions or physical impact. Etching includes wet etching and dry etching. The principle of wet etching is mainly to use a chemical solution to corrode the surface of the material, and to achieve the purpose of accurately removing the material by controlling the corrosion speed and time. Dry etching uses physical bombardment or a laser beam to directly act on the surface of the material, and removes the material by bombardment or evaporation. Etching technology has the advantage of high precision, and can process complex and fine patterns and structures, which is suitable for processing the fine texture of the surface of the roller 14. At the same time, the etching process has a simple processing method and good economic efficiency.

[0056] Using the etching process or the additive manufacturing process to process the roller 14 can achieve fine texturing of the outer surface of the roller 14, and can also make the processing cost low and the economy good.

[0060] The heat exchange plate is usually composed of two parallel metal plates connected by a series of heat-conducting materials. The surface of the heat exchange plate can be provided with fine scales or convex structures to increase the surface area of heat exchange.

[0061] The heat exchange plate surface precision texture forming device 100 (hereinafter referred to as the forming device 100) is a device for processing the texture of the surface of the heat exchange plate. The forming device 100 processes the heat exchange plate by a roller forming process to obtain a fine texture on the surface of the heat exchange plate.

[0062] The roller forming process deforms the metal under pressure by using rollers 10 with specific shapes or special textures. When the metal passes through these rollers 10, it will gradually deform into the required cross-sectional shape. The roller forming process precisely shapes and processes objects through roller force, ensuring the shape and size accuracy of the product.
