Problems solved by technology

[0005] The metal heat shaping method requires long-term high-temperature treatment of the side decorative strips. However, zirconium-based amorphous alloys are sensitive to high temperatures. Long-term high-temperature treatment will cause large changes in the properties of zirconium-based amorphous alloys, and are prone to failure. , so the first processing method is not suitable for the plastic modification of the side trim
In addition, the plasticity of the zirconium-based amorphous alloy is poor, the effect of oil pressure correction is not good, and the appearance of the side decorative strip is easily damaged by the oil pressure, so the second treatment method is not suitable for the plastic correction of the side decorative strip

Embodiment 1

[0040] This embodiment provides a shaping and correction method, which is suitable for the shaping and correction of side decorative strips. It is implemented by a shaping and correction device, which can not only perform shaping and correction on the length of side decorative strips, but also ensure that the performance of side decorative strips remains unchanged. and appearance is not damaged.

[0041] The side decorative strip includes two arc portions and a straight portion connecting the two arc portions. see figure 2 , the plastic correction method provided in this embodiment includes:

[0042] S10: Fix the straight part.

[0043] S20: Processing the inner surface of the arc portion to change the length of the side decorative strip.

[0044] It should be pointed out that the inner surface of the curved portion will eventually be attached to the housing of an electronic terminal such as a mobile phone, and its main appearance surface is the outer surface.

[0045] It...

Embodiment 2

[0056] The shaping correction device provided in this embodiment can be used to implement the shaping correction method provided in the embodiment of the present invention, and has corresponding functions and beneficial effects.

[0057] The shaping correction device is suitable for a side trim strip, and the side trim strip 1 includes two arc portions 101 and a straight portion 102 connecting the two arc portions 101 .

[0058] see image 3 , the plastic correction device includes:

[0059] a fixing jig 2 for fixing the straight portion 102;

[0060] The shaping mechanism is used to process the inner surface of the arc portion 101 to change the length of the side decorative strip 1 .

[0061] Specifically, the shaping mechanism includes:

[0062] A laser emitting mechanism 3, configured to irradiate the inner surface of the arc portion 101 with laser light to reduce the radius of the arc portion 101;

[0063] The laser time control device is used to control the irradiatio...

Abstract

The invention relates to the technical field of assembling machining, and particularly discloses a truing method and device. The truing method and device are suitable for a side decoration strip, theside decoration strip comprises two arc parts and a straight part connected with the two arc parts, and the method is characterized by comprising the step that the inner side surfaces of the arc partsare subjected to treatment, and the length of the side decoration strip is changed. According to the truing method and device, the length of the side decoration strip is subjected to truing, and it can be ensured that the property of the side decoration strip is not changed, and the appearance is not damaged.

Description

technical field [0001] The invention relates to the technical field of assembly and processing, in particular to a method and device for shaping and correcting. Background technique [0002] Zirconium-based amorphous alloy has the characteristics of high surface hardness, easy die-casting, high surface brightness and not easy to deform, so it is favored by mobile phone designers, and is often used to make side decorative strips of electronic terminals such as mobile phones or tablet computers. . [0003] see figure 1 , most of the side decorative strips 1 include two arc portions 101 and a straight portion 102 connecting the two arc portions 101 . The length of the side trim strip 1 after die-casting is relatively long, and its length is easily changed by heat in the subsequent processing (that is, the total length of the side trim strip 1 will be lengthened or shortened), and the change in length will cause subsequent assembly. Assembly breaks or steps affect the appeara...
