Embodiment Construction

[0020] For better understanding and implementation, the present invention will be further described below in conjunction with the accompanying drawings: a production process of a copper-aluminum transition terminal with limit constraints, including the following steps:

[0021] Step 1: Roll the copper-aluminum composite billet into round bars of various specifications;

[0022] The second step: complete the bright annealing of the round bar by adding a protective gas of argon. The main advantage of using argon protection for annealing is that it not only meets the conditions of high temperature annealing and residual oil stains on the burning surface, but also protects the surface of the material. Prevent oxidation, save the acid-base washing procedure, realize green production, avoid environmental pollution, and also save the post-treatment procedure of acid-base waste liquid;

[0023] Step 3: Cut to length according to the cutting size, and remove the surface burrs;

[0024...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of copper-aluminum composite materials, and in particular relates to a production process of a copper-aluminum transition terminal with limit constraints. Background technique [0002] As a kind of power fittings, terminal blocks are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Terminal blocks belong to the national standard general parts, there is a rigid demand in the market, and the consumption is very large. The traditional transition terminals are mainly produced by welding and flattening pure copper and pure aluminum. Due to the scarcity of copper, the price is expensive, and the production efficiency is not high; secondly, a very thin layer is welded on the surface of the flattened pure aluminum rod. Copper sheets are used to produce copper-aluminum transition terminals, but in this way, due ...
