Description

Processing technology for soft connection of copper braided wire
Technical Field
The invention relates to the technical field of copper braided wire flexible connection, in particular to a processing technology of copper braided wire flexible connection.
Background
The copper braided wire flexible connection is suitable for various high-voltage electrical appliances, automobiles and rectifying equipment, and the most common processing technology is as follows: the copper wire is twisted into a composite wire through single twisting and multiple twisting, then the composite wire is braided into a braided wire, the copper pipe is stamped at two ends of the braided wire, the soft connection resistance of the copper braided wire manufactured through the process is increased, the conductivity is reduced, and the product percent of pass is low. In addition, copper braided wire flexible coupling as connection structure, need with equipment welding or be connected the use, however current copper braided wire flexible coupling lacks the structure of being connected with equipment, needs the user to increase by oneself, has the inconvenience.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a processing technology for soft connection of copper braided wires, which improves the overall conductivity and tensile strength.
In order to achieve the purpose, the invention provides the following technical scheme: a processing technology for soft connection of a copper braided wire is characterized by comprising the following steps:
s1: preparing a copper braided wire, namely braiding copper wires into the copper braided wire with the width of 14-16mm on a braiding machine;
s2: cutting a copper braided wire with the length of 112-120 mm;
s3: assembling copper pipes, namely pressing one end of a copper braided wire by using a wire pressing die, and assembling the copper pipes at two ends of the copper braided wire;
s4: welding copper pipes, namely welding the copper pipes at two ends of a copper braided wire to obtain a rough blank;
s5: bending and forming, wherein the rough blank is bent by 45 degrees through a copper pipe at one end pressed by a pressing line die;
s6: cutting off the end face, and cutting off redundant copper pipes according to the design size of a drawing;
s7: shaping, namely drilling a hole at one end of the copper braided wire which is not pressed with a line by using a numerical control milling machine, and then milling round corners and removing burrs at two ends of the copper braided wire;
s8: cleaning, namely washing off oil stains on the surface of the rough blank, and removing water stains by using a centrifugal dryer;
s9: presetting brazing filler metal, and welding the brazing filler metal on a copper pipe at one end which is not drilled to obtain a primary finished product;
s10: performing secondary shaping, namely performing water polishing on the primary finished product, performing ultrasonic cleaning, and drying to obtain a finished product;
s11: and (5) inspecting, and packaging the finished product after inspecting.
The invention further comprises the following steps: the diameter of the pressing line die in the S2 is larger than 8mm, and the length of the pressing line is 30 mm.
The invention further comprises the following steps: the welding in S4 is molecular diffusion welding.
The invention further comprises the following steps: spot welding is used in S9.
The invention has the beneficial effects that: the copper pipe is welded at two ends of the copper braided wire by adopting molecular diffusion welding, so that the resistivity of the copper pipe can be effectively reduced, and the overall conductive performance and tensile strength of the flexible connection of the copper braided wire are improved; s5, bending and forming, so that the end face of a copper pipe on one side is 45 degrees, the copper braided flexible connection is required to be connected with three-phase electricity when in use, however, the actual installation space is small, the three wires are touched to cause the condition of sparking, the wires can be staggered through the copper braided flexible connection after the S3 step, the interference between a product and other structures is avoided, and the safety and the stability of the copper braided wire flexible connection when in use are improved; solder is preset on the copper pipe, and when the product is installed on equipment, the solder can be used for welding the copper pipe and the copper pipe, so that the practicability of the copper braided wire flexible connection is enhanced.
The present invention will be described in further detail with reference to examples.
