Embodiment 1
[0018] Embodiment 1: as Figure 1-4 Shown, a kind of light alloy thin plate and non-metallic thin plate rotary friction embossing connection method, comprises the steps:
[0019] 1) Pre-punching a hole in the middle of the non-metallic sheet 3, the hole diameter is larger than the diameter of the rotatable punch 1, so that the rotatable punch 1 and the hole in the middle of the non-metallic sheet 3 are matched;
[0020] 2) Install the light alloy thin plate 2 and the non-metallic thin plate 3 on the lower mold 4, and the light alloy thin plate 2 is used as the upper plate, and the non-metallic thin plate 3 is used as the lower plate;
[0021] 3) The rotatable punch 1 is connected to the computer control system, and the displacement parameters and speed parameters of the rotatable punch (1) are preset in the computer control system;
[0022] 4) When the rotatable punch 1 contacts the upper surface of the light alloy sheet 2, the computer control system controls the displacemen...

The invention relates to a rotary friction impressing connection method for a light alloy thin plate and a non-metal thin plate, and belongs to the novel technical field of thin plate material connection. According to the method, the light alloy thin plate and the non-metal thin plate are clamped on a lower die, the light alloy thin plate serves as an upper plate, and the non-metal thin plate serves as a lower plate; the displacement and rotation speed of a rotatable punch are controlled through a computer control system, when the rotatable punch is in contact with the upper surface of the light alloy thin plate, friction between the rotatable punch and the light alloy thin plate occurs to generate certain heat, and therefore the material flowability of the light alloy thin plate is improved; as the punch continues to move downwards, the upper and lower plates generate large plastic deformation under the function of the lower die, and finally, the effective connection between the lightalloy thin plate and the non-metal thin plate is achieved. The method has the advantages that the connection process is simple, and the effective connection between the light alloy thin plate and thenon-metal thin plate can be achieved without rivets or other connection mediums; the reliable and effective method is provided for achieving the connection between the light alloy thin plate and thenon-metal thin plate.
Description
technical field [0001] The invention relates to a method for connecting a light alloy thin plate and a non-metallic thin plate by rotating friction embossing, and belongs to the new technology field of thin plate material connection. Background technique [0002] Light alloys mainly refer to aluminum alloys, magnesium alloys and titanium alloys. At present, with the continuous improvement of people's green awareness, all walks of life pay more and more attention to the development of lightweight structures, making light alloys more and more widely used. However, as far as the existing connection technology is concerned, it is still a major difficulty to realize the connection of light alloy thin plates and non-metallic thin plates. Due to the relatively poor plasticity of light alloys, it is not easy to deform, and the non-metallic sheets are generally brittle and prone to breakage; therefore, even if the existing new technologies for sheet material connection such as self-p...
