Air-Hydraulic Intensifier Equipment and Technology Research of Clinching

Abstract

Base on clinching process, an air-hydraulic intensifier clinching devices was designed. In order to accurately control the quality of clinching, the displacement sensor and pressure sensor were joined in the control loop. So two different control feedback loops were founded. With two different ways of clinching tests, a clinching test method was founded, and the joint strength is analyzed. The result was that the shears strength and fracture strength in different directions of clinching samples are different.

Clinching for sheet materials

“…An air-hydraulic intensifier clinching device has been designed in which the displacement sensor and the pressure sensor were incorporated in the control loop so as to accurately control the quality of the clinching [ 88 ]. A clinching test method was found, based on experiments using two different control feedback loops with two different ways of clinching.…”
