Abstract
The utility model provided a profiled copper strip which is characterized in that a concave strip-shaped structure is arranged on the surface on one side of the profiled copper strip along the longitudinal direction of the strip. The copper strip is applied to the pins of processing circuits with high efficiency, low consumption, quickness and low cutting amount.
Description
Technical field
The utility model relates to a kind of banded copper material with special cross-section shape, and it has the high-precision section section, as integrated circuit, plastic packaging transistor blaster fuse frame material, can be widely used in industries such as electronics, electrical equipment.
Background technology
At present, electronics and information industry is as the rising industry in the economic development, become new growth engines, various copper circuit pins are as the element on basis, and its demand is very surprising, still, present ordinary flat copper strips is when producing copper pin, complex manufacturing, processing waste material are many, and the utmost point is unfavorable for raising the efficiency, and also is unfavorable for reducing cost.
And, the metal current resource is as non-renewable resource, along with demand is increasing with consumption, corresponding deposit will be fewer and feweri, therefore, in the world, metal is non-ferrous metal such as copper etc. particularly, and its price is surging continuously for a long time, and then cause the cost of copper pin to increase continuously, therefore how to improve the efficient of pin processing and reduce material consumption, not only can effectively reduce cost, and can save suitable resource, for giving birth to processing enterprise, has remarkable economic efficiency and value, for society, also have energy-saving and cost-reducingly, meet building a conservation-minded society that country advocates, walk the target and the direction of sustainable development.
The utility model content
The purpose of this utility model provides a kind of new copper band with special cross-section shape one, and copper strip of the present utility model can adapt to the little cutting of modern circuit pin or even not have cut.
The technical solution of the utility model is as follows:
A kind of section copper strip material is characterized in that: the surperficial upper edge band of described section copper strip material one side is vertically arranged with the spill banded structure.
The spill banded structure of described section copper strip material is positioned at a side of strip surface.
The width of the described spill banded structure of described section copper strip material is 5～80mm, and surplus width is 25～40mm.
The spill banded structure of described section copper strip material is positioned at the middle part of strip surface.
Surplus its height of the described band that is arranged in spill banded structure both sides or width have at least one inequality.
Surplus of the described band that is positioned at spill banded structure both sides is symmetrical arranged along recess longitudinal center vertical plane.
The spill banded structure of described section copper strip material is positioned at the both sides of strip surface.
Being provided with wedge shape between described spill banded structure and the surplus portion of the band of its side is connected.
Described copper strip adopts Cu alloy material, and wherein the Cu weight ratio is 99.75～99.82%, and the Fe weight ratio is 0.05～0.15%, and impurity total weight ratio is not more than 0.1%.
The utility model is according to the structure and the processing characteristic of circuit pin in the hyundai electronics industry, particularly process copper pin at present widespread usage Sheet Metal Forming Technology, existing ordinary flat copper strips cuts in the course of processing, the blanking amount is bigger, both caused the high defective of processing cost, cause a large amount of metals resources wastes again, be unfavorable for very much lasting, the long-run development of industry.
Copper strip has different-thickness in the utility model, can adapt to the different needs of copper pin different parts thickness in the Sheet Metal Forming Technology, avoid or reduced Cutting Process, promptly be convenient to processing in enormous quantities fast, the working (machining) efficiency of simultaneously having avoided big cutting output to bring again is low, spillage of material is big, the shortcoming that cost is high.
At the difference of different pin configuration, copper strip of the present utility model both can have " L " shape structure, also can have " recessed " shape structure, can also have " protruding " shape structure.The copper strip of " L " shape structure (being the side that the spill band structure is positioned at strip surface) wherein, its cross section has the thin characteristics of the thick side of a side, be fit to very much the sort of pin of processing two ends and have the structure of different-thickness, and for the copper strip (being the middle part that the spill band structure is positioned at strip surface) of " recessed " shape structure and the copper strip (being the both sides that the spill band structure is positioned at strip surface) of " protruding " shape structure, structure of the thin thick middle in its thick on both sides and thin in the middle or both sides is very suitable for processing two ends and has pin than thick structure.
The copper strip of " recessed " particularly of the present utility model shape structure, because its both sides can have different gauges than thickness portion, therefore, have adaptability more widely, it can design the copper strip of producing different size according to the concrete structure size of pin, therefore, can be perfectly and the production of pin be complementary, raise the efficiency to greatest extent and stock utilization, reduce cost.
Be provided with the syndeton of wedge shape between the surplus portion of the band of concave structure of the present utility model and its side, on the one hand, if there is not wedge structure to be connected, make the shoulder of avoiding existing the right angle between the adjacent two-part structure, both be convenient to the processing of band self, also helped pin processing thereafter.
