Description
Technical field
The invention belongs to technical field of copper aluminum composite material, relate in particular to a kind of plus limit constraints copper aluminium mistake
Cross the production technology of connecting terminal.
Background technology
The one kind of connecting terminal as electric armour clamp is all kinds of devices in connection and combinational electric system, plays transmission
The metal-ware of mechanical load, electrical load and certain protective action.Connecting terminal belongs to national standard general part, exists on the market
Rigid demand, and dosage is very big.Traditional transition terminal is mainly flattened by fine copper, fine aluminium welding to produce system
It makes, due to copper material rareness, expensive, productivity effect is not high；It is welded very secondly by the fine aluminium bar surface explosion of flattening
Thin one layer of copper sheet produces copper-aluminum transition connecting terminal, but so in use since welding generates larger resistance,
Calorific value is bigger during use, influences the performance of product.And the welding procedure of explosion weldering is also more complicated, pair sets
Standby requirement is also relatively high；Furthermore golden anchor electric power Pty Ltd passes through patent of invention CN106058606A《A kind of copper aluminium is multiple
Close the production technology of transition terminal》The simple manufacturing method of copper-aluminum transition connecting terminal is realized, but in that patent
Need to carry out pre-treatment, including pickling, cleaning to material, alkali cleaning, cleaning and etc. processing material surface oil stain, and largely make
With acid solution lye and the existing green production advocated in China, environmental protection production is disagreed, and the post-processing of acid-base waste fluid is also very troublesome；
Additionally due to the invention is in the process free extension clapping flat, it, can transversely, longitudinally after compression for the attribute of this life of material
It flows, but lateral flow is big compared to longitudinal flow so that material claps flat bulge lateral in the process too greatly and so that the copper on surface
Layer tearing, causes rejection rate higher, production cost is too big.
Invention content
The present invention provides the production technologies of a kind of plus limit constraints copper-aluminum transition connecting terminal, solve background
The disadvantage that production technology rejection rate in technology is higher, production cost is big.
The technical proposal of the invention is realized in this way：A kind of life of plus limit constraints copper-aluminum transition connecting terminal
Production. art includes the following steps：
The first step：Copper-Aluminum compound strand is rolled into the pole of various specifications；
Second step：Protective gas by the way that argon gas is added completes the bright annealing of pole；
Third walks：According to blank size scale sawing, and remove surface spikes；
4th step：By friction welding (FW) by the aluminium bar firm welding of the aluminium core of Copper-Aluminum compound pole and transition terminal；
5th step：The copper-aluminum transition connecting terminal welded was photographed into appointed thickness in limit constrains mold；
6th step：Rush centre bore, cutting edge shaping；
7th step：Oscillation cleaning, drying, packaging shipment in the oscillator that abrading-ball is added；
Preferably, the limit constraint mold includes punch-pin, and die socket is equipped with below punch-pin, and female die block is equipped in die socket, recessed
It is equipped with hydraulic mandril below module, material is placed between female die block and punch-pin.
The beneficial effects of the invention are as follows：The manufacturing technique method of the present invention has abandoned the cleaning of acid ＆ alkali liquid, realizes green
Production reduces the pollution to atmospheric environment, also avoids the post processor to acid-base waste fluid, not only meet environmental requirement, and
And spending to liquid waste processing is also reduced, further save production cost；
The limit restraint device that the present invention designs, increases material pressure, it is therefore prevented that transverse direction bulge when material freely claps flat
The defect for tearing surface layers of copper, makes material mainly flow along longitudinal direction, greatly improves product lumber recovery, reduces defect rate；
For the present invention by vibrating processing of the abrading-ball to material surface burr, can not only polish off material surface burr makes material surface
It is rounder and more smooth, and the friction repeatedly of abrading-ball and material enhances material surface intensity, improves the materials'use service life；
The manufacturing technique method of the present invention is simple and fast, can realize the operating type of assembly line and improve production efficiency, saves
About production cost reduces human resources input；
The degree of automation of the present invention is higher, and feeding, discharging can be completed by the hydraulic tool of design.
Description of the drawings
Fig. 1 is the structural schematic diagram of the limit constraint mold of the present invention.
Part explanation：1, punch-pin, 2, material, 3, female die block, 4, die socket, 5, hydraulic mandril.
Specific implementation mode
For a better understanding and implementation, the invention will be further described below in conjunction with the accompanying drawings：One kind plus limit constraint
The production technology of the copper-aluminum transition connecting terminal of condition, includes the following steps：
The first step：Copper-Aluminum compound strand is rolled into the pole of various specifications；
Second step：Protective gas by the way that argon gas is added completes the bright annealing of pole, and annealing is main good using argon gas protection
Place was under conditions of not only having met high annealing and burning surface oil residues, but also played a protective role to material surface, prevented
Oxidation eliminates soda acid washing procedure, realizes green production, avoids the pollution to environment, also eliminates acid-base waste fluid post-processing
Program；
Third walks：According to blank size scale sawing, and remove surface spikes；
4th step：By friction welding (FW) by the aluminium bar firm welding of the aluminium core of Copper-Aluminum compound pole and transition terminal, aluminium-aluminium welds
It connects and belongs to same material welding, welding procedure is ripe simple, and firm welding, it is not easy to be broken, xenogenesis material will not occurs
Material welding leads to the increased defect of welding kesistance, extends the materials'use service life, has saved use cost；
5th step：The copper-aluminum transition connecting terminal welded was photographed into appointed thickness in limit constrains mold, thickness is according to pole
Diameter determine.Convex film 1 is an entirety, and cavity plate is divided into two pieces, including die socket 4 and female die block 3, female die block 3 and hydraulic pressure
Mandril 5 is bolted, material copper-aluminum transition connecting terminal 2 clap it is flat after make hydraulic mandril 5 copper aluminium mistake by hydraulic cylinder
The jack-up of connecting terminal 2 is crossed, the hydraulic push rod being then arranged by side, which shifts material onto, to be unloaded in material frame.Add limit to constrain, has made material
Material is all pressurized in upper and lower, both sides four on face, and material can only generate plastic deformation along longitudinal, according to material properties, material institute
More by pressure, material is more conducive to be plastically deformed, and limit constraint claps flat method and not only increases product lumber recovery, and is equipped with certainly
Dynamic hydraulic stripper tooling, greatly improves productivity, and realizes the semi-automation of production, reduces cost of labor；
6th step：Rush centre bore, cutting edge shaping；
7th step：Oscillation cleaning, drying, packaging shipment in the oscillator that abrading-ball is added, by vibrating the grinding of abrading-ball, and
Flowing water is passed to, not only polishes off the burr left when punching sizing, but also the friction of abrading-ball and material surface can also reinforcing material
Surface strength improves service life, and flowing water, which takes away burr, keeps material surface cleaner, and only need to dry up moisture can pack hair
Goods.
