No rivet connection technology is a new type of connection method, which is gradually replacing the traditional backward connection technology. Because of the connection methods used so far
There are economic and technical problems. We only take spot welding as an example, its equipment is expensive, the connection cost is high, it is difficult to connect the multilayer board
And the coated plate or aluminum, copper and stainless steel plate, and the spray plate and different material plate, thickness difference and middle plate
Laminated plates are not connected. At the same time, the spot welding connection has destroyed the surface coating of the plate, which will produce thermal deformation. And the connection process
All unreliable factors can not be carried out without damage detection. In addition, using the traditional connection method, the single piece connection cost is too high, such as in
A riveting or threaded connection method, the preparation of the work together with the corresponding transmission and spare parts costs, it will cause a high cost.
No rivet connection technology using plate pressing machine and our company design and manufacture of special connection mold, through a moment of high pressure processing,
According to the deformation of plate material itself the cold extrusion, formed a certain tensile stress concentration and shear strength of the embedded dot, you can
Connect two or more layers of different materials with different thickness. There is no requirement for the surface of the panel, and the connection point is not required.
The original coating, paint layer on the surface of the piece is not damaged. The connection process automation degree is high, can be single point or multi-point at the same time connection, and can carry on without damage
Connection strength testing and automatic monitoring of the whole process, high production efficiency
