Description
Technical field
The invention belongs to the Machining Technology field, relate in particular to a kind of portable low-voltage electromagnetism riveter that is applied to Electromagnetic riveting technology.
Background technology
Riveted joint is a kind ofly to make the MACHINERY JOINT of field extensive use at Aero-Space, automobile, electronic apparatus etc., and it mainly comprises the hammering riveted joint, press and process form such as electromagnetic riveting.
The hammering riveted joint is the clinching method that a kind of quilt generally adopts.Utilize during riveted joint and impact the head that the continuous several times of strength hit rivet bar, rivet bar is radially flowed, the riveting that has formed union piece becomes head, and its process characteristic is: the impulsive force that needs is bigger; Riveted parts and clincher tool have bigger vibrations; Rivet bar head discontinuity equalization, unstable product quality; Riveting becomes head surface of poor quality, has destroyed the institutional framework of rivet bar head material simultaneously; Labor intensity of operating personnel is big; The noise decibel is high, and operating personnel's physical and mental health is had adverse effect.When rivet bar to strain hardening and strain-rate sensitivity, as titanium alloy, carry out common hammer riveting and add man-hour, rivet produces cracking easily at the heading position, and riveting quality is very unstable.
