The invention provides a production process of a
copper-aluminum transition wiring terminal with limiting constraint conditions. The process comprises the following steps: step 1, rolling the
copper-aluminum composite
casting blank into round bars of various specifications; step 2, completing the bright annealing of the round bars through the protection gas added with
argon; step 3, fixing a rulerand sawing according to the blanking size, and removing burrs on the surface; step 4, firmly
welding the aluminum core of the
copper-aluminum composite
round bar and the aluminum rod of the transition wiring terminal through
friction welding; step 5, making the welded copper-aluminum transition wiring terminal be in a specified thickness within a limit constraint mold; step 6,
punching a center hole,
cutting edges, and shaping; and step 7, performing oscillation cleaning,
drying, packaging, and discharging in the oscillator with
grinding balls. The acid-base cleaning process is abandoned andis changed into flowing
water flow oscillation cleaning, and the material is forced to flow along the longitudinal direction by adding the limiting constraints, the phenomenon that the bulging is cracked during the flattening process is avoided, the
rejection rate is reduced, and the production efficiency is greatly improved.
