Abstract

The invention relates to a copper ferronickel cable strong in flexural endurance. The copper ferronickel cable comprises a copper core. The copper core is composed of, by weight percent, 0.1%-0.8% of silicon, 0.02%-0.08% of phosphorus, 0.1%-0.8% of iron, 0.02%-0.05% of nickel, 0.03%-0.09% of zinc, 0.02%-0.06% of arsenic, 0.04%-0.09% of lead and the balance of copper and inevitable impurities. The copper ferronickel cable has the advantages of being good in electricity conducting effect and strong in flexural endurance. The copper ferronickel cable is especially suitable for being used under complicated and harsh working environments of a robot, a working mechanical hand and the like and can achieve the special effect under high-speed, continuous and long-time rotation.

Description

The copper iron-nickel alloy cable that anti-bending is strong

Technical field

The present invention relates to a kind of alloy field, especially a kind of be suitable for that various mechanical arms use have a strong and higher strong copper iron-nickel alloy cable of anti-bending of current on time of anti-bending.

Background technology

Cable is to be made by conductor outsourcing insulation and the protective layer of one or more mutually insulated, with electric power or information from a wire that is transferred to another place.The core of cable generally is to adopt copper or aluminum to form, because copper core has excellent conductance, so, the cable of the overwhelming majority is made take copper as material, but, simple copper cable is no problem as power cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable etc.But, when being used for control cables or compensating cable, when especially using in robot, because this cable needs frequent bending, so cable need to have fabulous anti-bending, simultaneously, also need to have excellent conductive performance, this just need cable have anti-bending strong with good electric conductivity, although traditional copper cable has good electric conductivity, it can not make the strong cable of anti-bending.

Summary of the invention

In order to overcome the problems referred to above, the invention provides the strong copper iron-nickel alloy cable of a kind of anti-bending, this cable not only conductive effect is good, but also has very strong anti-bending performance.

Technical scheme of the present invention is: provide a kind of anti-bending strong copper iron-nickel alloy cable, comprise the copper core, described copper core comprises that the component of following weight percentage forms:

Silicon 0.1-0.8%; Phosphorus 0.02-0.08%; Iron 0.1-0.8%; Nickel 0.02-0.05%; Zinc 0.03-0.09%; Arsenic 0.02-0.06%; Plumbous 0.04-0.09%; Copper and inevitable impurity surplus.

More preferably, described copper core comprises that the component of following weight percentage forms:

Silicon 0.3-0.5%; Phosphorus 0.03-0.05%; Iron 0.3-0.5%; Nickel 0.02-0.05%; Zinc 0.05-0.07%; Arsenic 0.02-0.06%; Plumbous 0.06-0.08%; Copper and inevitable impurity surplus.

The present invention not only conductive effect is good, but also has the strong advantage of anti-bending.The present invention is particularly suitable for using under the harsh operational environment in the complexity such as robot and work robot, and can at a high speed, continuously, its special-effect of performance under the long-time state that rotates.

Embodiment

Embodiment 1

The copper iron-nickel alloy cable that anti-bending is strong comprises the copper core, and described copper core comprises that the component of following weight percentage forms:

Silicon 0.1%; Phosphorus 0.02%; Iron 0.1%; Nickel 0.02%; Zinc 0.03%; Arsenic 0.02%; Plumbous 0.04%; Surplus is copper and inevitable impurity.

Embodiment 2

The copper iron-nickel alloy cable that anti-bending is strong comprises the copper core, and described copper core comprises that the component of following weight percentage forms:

Silicon 0.3%; Phosphorus 0.03%; Iron 0.3%; Nickel 0.02%; Zinc 0.05%; Arsenic 0.02%; Plumbous 0.06%; Surplus is copper and inevitable impurity.

Embodiment 3

The copper iron-nickel alloy cable that anti-bending is strong comprises the copper core, and described copper core comprises that the component of following weight percentage forms:

Silicon 0.5%; Phosphorus 0.05%; Iron 0.5%; Nickel 0.05%; Zinc 0.07%; Arsenic 0.06%; Plumbous 0.08%; Surplus is copper and inevitable impurity.

Embodiment 4

The copper iron-nickel alloy cable that anti-bending is strong comprises the copper core, and described copper core comprises that the component of following weight percentage forms:

Silicon 0.8%; Phosphorus 0.08%; Iron 0.8%; Nickel 0.05%; Zinc 0.09%; Arsenic 0.06%; Plumbous 0.09%; Surplus is copper and inevitable impurity.

The copper iron-nickel alloy cable that the anti-bending of the present invention is strong compares with existing traditional copper cable, and its result is as follows:

Test method among the present invention: about 90 the degree bend tests (R=10mm, W=1kg); Cable dimension: 0.2SQ * 4P; About respectively be calculated as 1 index.

As can be seen from the above table, the fully flexural number of insulation of the present invention is comparative sample 1 or comparative sample 2 about 4.5 times to 22.2 times, the conductance of supposing comparative sample is 1, conductance of the present invention is 0.83-0.90 times of comparative sample, although, conductance descends to some extent, still, also is in the scope of closing the symbol requirement.
