5G mobile phone composite material processing technology

Abstract

The invention discloses a 5G mobile phone composite material processing technology. The 5G mobile phone composite material processing technology comprises the following steps that 1, a titanium alloy middle frame is manufactured through a 3D printer, titanium alloy powder is used for performing 3D laser printing to form a titanium alloy middle frame blank, and then the titanium alloy middle frame blank is put into a vacuum sintering furnace to be subjected to vacuum annealing; and 2, a plastic structural part is integrally formed on the titanium alloy middle frame through injection molding. The 3D printer in the step 1 comprises a protection box, a laser working bin, an operation opening, a sealed bin door, a safety switch, a lifting bin, a lifting fixing device, a powder circulating system, a driving bin and a powder spreading mechanism. The sealed cabin door and the safety switch are arranged, so that the stability and safety of airflow in the laser printing process are improved; the lifting fixing device can improve the size precision of parts in the printing process, and movement of the parts is reduced; and according to the titanium alloy frame printed through the method, the plastic structural part is formed through injection molding, the structure is reliable, the strength is high, and procedures are simple.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a 5G mobile phone composite material processing technology. Background technique [0002] With the rapid development of science and technology, 5G mobile phones with titanium alloy frame structure lead the current market trend, and it is also a trend to apply titanium metal to 5G mobile phones, which has the same lightweight properties as titanium alloys. Since titanium alloys are harder and more corrosion-resistant than titanium alloys, titanium alloys have a wider prospect of being used in 5G mobile phones in the future. However, the processing process of metal 5G mobile phones is now through CNC subtractive machining or high-temperature casting. The cost and reduce the yield of the product. 3D printing technology is an additive manufacturing process that adds materials layer by layer.

However, the processing process of metal 5G mobile phones is now through CNC subtractive machining or high-temperature casting. cost and reduce product yield

3D printing technology is an additive manufacturing process that adds materials layer by layer. It has a high material utilization rate and a high degree of automation. It has a strong processing ability for parts with complex shapes, and its application in industrial production is becoming more and more popular; Existing 3D printers have some obvious defects. Firstly, the existing 3D printers mostly use left and right hinged hatches, which can achieve high airtightness. However, after the hatches are opened, it is difficult to Exposing the entire operation port will hinder and interfere with the operation of the operator's hands, which is very inconvenient for actual use; secondly, during the printing process of the existing 3D printer, the printed parts are adhered to the tray by sintering, but due to the The surface is relatively flat. During the printing process, the fixing of the parts is relatively unreliable. With the accumulation and flow of powder, it will have a certain impact on the placement of the parts, resulting in size deviation, and even the entire part will be scrapped; Or, after the printing is completed, the parts will be buried in the metal powder, and the entire printing pool needs to be opened to take out the parts, which is very inconvenient. At the same time, it also causes difficulties for the secondary recovery of the powder
