Connect new technical field.
Background technique
Light-alloy refers mainly to aluminium alloy, magnesium alloy and titanium alloy etc., now with the continuous improvement of people's Green Consciousness, respectively
Each industry of row increasingly payes attention to development structure lightweight, so that light-alloy is more and more widely used.However, with regard to existing connection
For technology, realize that the connection of light-alloy thin plate and nonmetallic thin plate is still a big difficulty.Since light-alloy plasticity is relatively poor,
It is not susceptible to deformation, rather than the universal brittleness of sheet metal is larger, it is prone to be broken；Even if thus using existing self-pierce riveting
It connects, imprint the light sheet materials such as connection, Friction Stir Welding connection new technology, be still difficult or even can not achieve to light-alloy thin plate
With effective connection of nonmetallic thin plate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of light-alloy thin plates and nonmetallic thin plate spin friction coining to connect
Method is connect, to solve the problems, such as that light-alloy thin plate is difficult to realize effectively connect with nonmetallic thin plate.
The technical solution adopted by the present invention is that：A kind of light-alloy thin plate and nonmetallic thin plate spin friction imprint connection side
Method includes the following steps:
1）It is punched in advance in the middle part of nonmetallic thin plate 3, aperture is greater than rotatable 1 diameter of formed punch, makes rotatable formed punch 1 and non-
The interporal lacuna cooperation at 3 middle part of sheet metal；
2）Light-alloy thin plate 2 and nonmetallic thin plate 3 be loaded on lower mold 4, and light-alloy thin plate 2 is used as upper plate, it is nonmetallic thin
Plate 3 is used as lower plate；
3）Rotatable formed punch 1 is connect with computer control system, rotatable formed punch (1) is preset in computer control system
Displacement parameter and rotary speed parameter；
4）When rotatable formed punch 1 being made to contact 2 upper surface of light-alloy thin plate, computer control system controls the position of rotatable formed punch 1
Shifting and rotation speed, rub between rotatable formed punch 1 and light-alloy thin plate 2, generate heat, and it is thin thus to improve light-alloy
The material flowability of plate, with rotatable 1 Continued downward motion of formed punch, the big change of plasticity occurs under lower mould action for upper and lower plate
Shape, the final effective connection realized between light-alloy thin plate 2 and nonmetallic thin plate 3.
Preferably, the lower mold 4 is monolithic mold.
Specifically, in the computer control system preset rotatable formed punch 1 displacement parameter and rotary speed parameter root
It is set according to the material and thickness of light-alloy thin plate 2 and nonmetallic thin plate 3.
The beneficial effects of the invention are as follows：Joining Technology is simple, without the connection medium such as rivet, it can be achieved that thin to light-alloy
Effective connection of plate and nonmetallic thin plate.It is intended that realize the connection of light-alloy thin plate and nonmetallic thin plate provide it is a kind of reliable and
Effective method.
