Referring to fig. 1, most of the side molding strips 1 include two arc-shaped portions 101 and a straight portion 102 connecting the two arc-shaped portions 101. The side trim strip 1 after die-casting is long, and the length thereof is easily changed by heat in the subsequent processing process (that is, the total length of the side trim strip 1 is lengthened or shortened), and the change of the length can cause assembly break or step in the subsequent assembly, which affects the appearance of the mobile phone and the like.
For the condition that the length of a workpiece is changed due to heating, the traditional treatment methods are two: firstly, the workpiece is shaped and corrected by using a metal thermal shaping method; and secondly, shaping and correcting the workpiece in an oil pressure mode.
The metal thermal shaping method needs to perform long-time high-temperature treatment on the side decorative strip, however, the zirconium-based amorphous alloy is sensitive to high temperature, and the performance of the zirconium-based amorphous alloy is greatly changed and is easy to be poor due to the long-time high-temperature treatment, so that the first treatment method is not suitable for shaping and correcting the side decorative strip. In addition, the zirconium-based amorphous alloy has poor plasticity and poor oil pressure correction effect, and the oil pressure is liable to damage the appearance of the side molding, so the second treatment method is also not suitable for the shaping correction of the side molding.
Therefore, there is a need for a shaping and correcting method that can not only carry out shaping and correcting on the length of the side trim strip, but also ensure that the performance and the appearance of the side trim strip are not changed.

Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the referred devices or elements must have the specific orientations, be configured to operate in the specific orientations, and thus are not to be construed as limitations of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
The embodiment provides a shaping and correcting method which is suitable for shaping and correcting a side decorative strip and is implemented by a shaping and correcting device, so that the shaping and correcting can be carried out on the length of the side decorative strip, and the performance and the appearance of the side decorative strip can be ensured to be unchanged.
The side trim strip includes two arc portions and a straight portion connecting the two arc portions. Referring to fig. 2, the shaping correction method provided in this embodiment includes:
s10: the straight portion is fixed.
S20: the inner side surface of the arc portion is processed to change the length of the side trim strip.
It should be noted that the inner surface of the arc-shaped portion will eventually be attached to the housing of the electronic terminal such as a mobile phone, and the main appearance surface is the outer surface.
It can be understood that, the conventional metal hot shaping method needs to heat up the whole side trim strip, and the conventional oil pressure method needs to clamp oil pressure on the inner side and the outer side of the side trim strip, that is, the conventional treatment method cannot only carry out shaping correction on the inner side surface of the arc part, which may cause performance change or appearance damage of the side trim strip. The shaping and correcting method provided by the embodiment only treats the inner side surface of the arc-shaped part, and does not influence the internal structures of the arc-shaped part and the flat part, so that the performance of the side decorative strip is not influenced; the outer side surfaces of the arc-shaped portion and the flat portion are not affected, so that the appearance of the side trim is not affected.
S201: if the length of the side trim strip is too long and needs to be shortened, the inner surface of the arc portion is irradiated with laser light to reduce the radius of the arc portion.
It should be noted that, generally, the time of the laser irradiation treatment is very short, the light energy of the laser is irradiated onto the arc portion and then converted into heat energy, the heat energy cannot reach the inside of the arc portion in a short time, and only can be transmitted along the inner side surface of the arc portion, and the inner side surface of the arc portion is heated and then shrinks, so that the inner diameter of the arc portion is reduced, and finally the length of the side decoration strip is shortened.
Optionally, the irradiation time of the laser irradiation is controlled to reduce the radius of the arc portion to a preset value.
In this embodiment, in order to conveniently use the same laser emission mechanism to carry out the shaping correction to different side trim strips, a fixed laser emission mechanism can be used, that is, the energy carried by the laser emitted by the laser emission mechanism in unit time remains unchanged, and the total amount of energy received by the arc-shaped portion can be changed by changing the irradiation time. The longer the irradiation time is, the larger the total energy amount is, the more obvious the deformation of the arc-shaped part is, and the larger the reduction of the radius is; the shorter the irradiation time, the smaller the total energy amount, the less noticeable the deformation of the arc portion, and the smaller the reduction in radius.
S202: if the length of the side trim strip is too short and needs to be increased, the inner surface of the arc portion is subjected to a blast impact treatment to enlarge the radius of the arc portion.
It should be noted that, in general, the blast nozzle for blasting is aligned with the inside surface of the arc portion without affecting the appearance of the outside surface of the arc portion. The sandblast impact treatment can be carried out by subjecting the inner side surface of the arc portion to an outward pressure by the impact of sandblasting, and the radius of the arc portion can be enlarged by maintaining the pressure for a certain period of time, thereby lengthening the length of the side molding.
Optionally, the blasting time of the blasting impact treatment is controlled to enlarge the radius of the arc-shaped portion to a preset value.
In this embodiment, for conveniently using same sandblast mechanism to carry out the plastic correction to the side trim of difference, can use fixed sandblast mechanism, be about to spout sand volume and sandblast pressure and fix, change the radius enlarged scale that sandblast time just can change arc portion. The longer the sand blasting time is, the more obvious the deformation of the arc-shaped part is, and the larger the radius expansion amount is; the shorter the blasting time is, the less the deformation of the arc-shaped portion becomes and the smaller the amount of radius expansion becomes.
The shaping and correcting method provided by the embodiment can be used for correcting the length of the side decorative strip in the shaping and correcting technical field, and the length of the side decorative strip can be adjusted under the condition of ensuring that the internal performance and the external appearance of the side decorative strip are not changed by processing the inner side surface of the arc-shaped part, so that the yield of the side decorative strip is improved, the resource waste is reduced, and the economic benefit is improved.
