[0024] Embodiment 1, see Figure 1 The utility model discloses an attendance machine shell of imitating stainless steel, including aluminum alloy base plate 1, the one side of aluminum alloy base plate 1 is provided with wire drawing layer 2 and oxidation layer 3 in the direction of away from aluminum alloy base plate 1 in proper order, and the other side of aluminum alloy base plate 1 is equipped with oxidation layer 3.

[0025] It should be noted that by wire drawing treatment to the outer surface of the aluminum alloy base material 1, a wire drawing layer 2 with stainless steel mechanical wire drawing lines is formed on the outer surface of the aluminum alloy base material 1. Then, an oxidation film is covered on the outer surface of the wire-drawn aluminum alloy base material 1 by electroplating oxidation process to form an oxidation layer 3. The oxidation layer is attached to the outer surface of the aluminum alloy base material 1, making the aluminum alloy base material 1 present a stainless steel color, which further improves the appearance quality of the attendance machine shell. In addition, the outermost oxidation layer 3 of the aluminum alloy base material 1 can effectively isolate oxygen and moisture in the air, acting as a protective layer and effectively delaying the corrosion process of the aluminum alloy base plate by the external environment.

[0026] In some embodiments, the aluminum alloy base plate 1 is one of the I-VIII series of alloy aluminum plates.

[0027] Preferably, when the aluminum alloy base plate 1 is I series, the model number is one of 1050, 1070, 1080, 1085 and 1100.

[0028] Preferably, when the aluminum alloy base plate 1 is II series, the model number is one of 2014, 2024 and 2A16.

[0034] Preferably, when the aluminum alloy substrate 1 is of the VIII series, the model is 8011.

[0035] It should be noted that the surface of the aluminum alloy substrate 1 is covered with an oxide film, which can effectively isolate air and oxygen, thereby achieving the purpose of improving corrosion resistance. Therefore, in some embodiments, when selecting the performance of the aluminum alloy substrate 1, more emphasis can be placed on the heat resistance of the aluminum alloy substrate.

[0036] In some embodiments, the thickness of the aluminum alloy substrate 1 is 1.5-5mm.

[0037] Specifically, the thickness of the aluminum alloy substrate 1 is one of 2.0mm, 2.5mm, 3.5mm.

[0038] It should be noted that the aluminum alloy substrate 1 with the above thickness can provide certain structural strength for the metal shell, so that it can resist various external forces in daily life and ensure that the normal function of the attendance machine is maintained.

[0039] In some embodiments, the wire-drawing layer 2 has a mechanical wire-drawing pattern.

[0040] Specifically, the wire-drawing layer 2 is polished by a sand belt with a model of 220#. Since the sand belt with a model of 220# usually has a finer abrasive grain size, the aluminum alloy substrate 1 can present a more smooth and delicate mechanical wire-drawing pattern during polishing.

[0041] Preferably, the depth of the mechanical wire-drawing pattern is 10-20μm.

[0044] Preferably, the mechanical drawing lines are long drawing lines.

[0045] It should be noted that adjusting the mechanical drawing lines on the outer surface of the aluminum alloy base 1 to straight and uniform straight-line mechanical drawing lines can give the aluminum alloy base 1 a simple, regular, and modern visual effect.

[0046] In some embodiments, the thickness of the oxidation layer 3 is 10-20 μm.

[0047] Specifically, the thickness of the oxidation layer 3 is 10 μm.

[0048] It should be noted that preparing the oxidation layer 3 to the above-mentioned specific thickness can not only effectively block the corrosive substances from the outside and improve the stability of the aluminum alloy base 1, but also prevent the increase in processing difficulty caused by the over-thickness of the oxidation layer 3, or prevent the oxidation layer 3 from becoming hard and brittle due to the over-thickness of the oxidation layer 3.

[0049] Embodiment 2, see Figure 2 In the embodiments of the present application, an attendance machine prepared from a stainless steel-imitating attendance machine shell is provided.

[0050] In some embodiments, the corner portions 4 are all in arc shapes.

[0051] In some embodiments, the radius of the corner portions 4 is R6.

[0052] It should be noted that the attendance machine prepared from the stainless steel-imitating attendance machine shell has the characteristics of good heat dissipation, strong corrosion resistance, and high ornamental value; in addition, the radius of the corner portions 4 affects the safety and ornamental value of the attendance machine to a certain extent. In some embodiments, setting the radius of the corner portions 4 to R6 can further improve the fluency and aesthetic degree of the attendance machine; at the same time, it can further reduce the local stress of the corner portions 4, so that the attendance machine is not easy to be damaged due to external impact; finally, from the safety point of view, the round corner design can also provide higher safety for the user.

[0053] The above is the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the examples, for those skilled in the art, the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
