Embodiment Construction

[0019] Specific embodiments of the present invention will be described below.

[0020] At first introduce the manufacturing method of the copper-iron alloy that conductive spring plate of the present invention adopts, manufacturing process is as follows:

[0021] Step a, dissolving high-quality copper in an electric furnace. Generally, copper with a purity greater than 99.9% is called high-quality copper. Put the broken copper pieces into the electrical furnace for stirring, raise the temperature above the melting point of copper (810.24k), and deoxidize after melting.

[0022] (1) For dehydrogenation, the partial pressure of oxygen is kept at a high level, and the range of partial pressure of oxygen is 1.5atm~3atm. At the same time, keep the temperature adjusted to 50°C to 100°C above the melting point, so that the oxygen element on the molten copper will increase, and the hydrogen will be separated regularly, so as to carry out the dehydrogenation process. The phase law h...

Abstract

The invention provides a manufacturing method of an electroconductive spring plate, which comprises the following steps that Step one, pretreatment is performed, and a clumpy copper-iron alloy is subjected to calendering treatment to be strip-shaped; Step two, the strip-shaped copper-iron alloy obtained in Step one is heated to a solid-solution temperature, and then cooled rapidly, and plastic deformation is performed on the copper-iron alloy when the copper-iron alloy is cooled to a temperature stage when no iron is precipitated; Step three, a cold chamber calendering process is performed: in an age hardening temperature stage when iron is dissolved out, a copper alloy after the plastic deformation is added in a room temperature calendering process; Step four, an age hardening process is performed: the alloy is kept at the age hardening temperature for the scheduled time; and Step five, Step three and Step four are performed repeatedly till 0.2% endurance of the electroconductive spring plate is greater than 850MPa. The electroconductive spring plate manufactured by the manufacturing method has high-performance strength and high-performance electric conductivity.

Description

technical field [0001] The invention relates to a conductive spring plate, and also relates to a method for manufacturing the conductive spring, which belongs to the field of metallurgy. Background technique [0002] Copper alloys containing 0.5% to 3% of beryllium have been mainly used as materials sharing electrical conductivity and mechanical strength. This beryllium compound contains toxicity. Although not toxic after being made into the final product. However, once the dust containing beryllium is inhaled during machining or welding, it will have a serious impact on the lungs and is dangerous. In addition, according to IARC (International Clinical Anesthesiology) survey, beryllium compounds can cause cancer. Contents of the invention [0003] The object of the present invention is to provide a conductive spring plate and its manufacturing method, so as to solve the above problems. [0004] The present invention provides a kind of preparation method of conductive s...
