Mobile phone body frame blank bending machining technology

Abstract

The invention discloses a mobile phone body frame blank bending machining technology. The mobile phone body frame blank bending machining technology comprises the following technology steps that a strip-shaped blank rolled, formed and wound around an unreeling disc is unreeled into a straightening mechanism; the straightening mechanism is used for straightening the strip-shaped blank; the straightened strip-shaped blank is continuously unreeled on the unreeling disc and stretches out of the straightening mechanism under the traction action of a traction wheel in the straightening mechanism; part of the strip-shaped blank stretching out of the straightening mechanism is bent into a J shape through a bending mechanism; the strip-shaped blank is continuously unreeled on the unreeling disc andstretches out of the straightening mechanism by a section of length under the continuous traction action of the traction wheel in the straightening mechanism; part of the strip-shaped blank stretching out of the straightening mechanism is bent into a U shape through the bending mechanism; and the U-shaped blank is shorn, and a mobile phone body frame blank is formed. The mobile phone body frame blank bending machining technology changes the original situation that CNN machining and carving are adopted for forming mobile phone body frames of 5G smart mobile phones, mobile phone upper frames orlower frames are directly bent and machined, and material consumption is reduced.

Description

technical field [0001] The invention relates to a bending processing technology for a frame blank of a mobile phone body. Background technique [0002] With the vigorous development of the communication industry, 5G mobile phones have become the general trend. Compared with 4G mobile phones, 5G mobile phones have faster network and communication, low latency, and more accurate positioning through network slicing technology. It receives and sends more information, and the increase in the area of ​​mobile phone components and antennas poses higher challenges to the layout design and industrial design of mobile phones; but a common problem with smartphones is that they are not resistant to falling, and the frame only relies on rubber structures, resulting in The frame strength is low, and the anti-drop effect is not ideal.

It receives and sends more information, and the increase in the area of ​​mobile phone components and antennas poses higher challenges to the layout design and industrial design of mobile phones; but a common problem with smartphones is that they are not resistant to falling, and the frame only relies on rubber structures, resulting in The frame strength is low, and the anti-drop effect is not ideal

In order to solve this problem, major mobile phone manufacturers are trying to strengthen the strength of the frame of the mobile phone body as much as possible, but another problem that follows is that when using higher strength materials to manufacture the mobile phone body, since the frame is similar to A rectangular frame with four rounded corners, after using high-strength materials, its hardness is also greatly increased. If the aforementioned rounded corners are manufactured by bending technology, the hardness HV is greater than 300 during bending, which is difficult to bend and has high bending accuracy. Therefore, the current method is to CNC process and carve it out (or process four straight bars, four curved bars and then combine them into the final frame), but this way of processing, the material loss is too large
