Abstract
A disclosed processing method for a nickel iron low-carbon steel iron-nickel- cobalt alloy special pipe material comprises the concrete steps: performing forging on an alloy ingot for multiple times to prepare a rod; performing hot-working perforating on the rod to form a pipe blank; performing acid washing, cold rolling and annealing processing on the pipe blank, repeating for multiple times, and drawing the circular pipe into a rectangular pipe; performing drawing shaping on the rectangular pipe again; and correcting the linearity and the parallelism of the rectangular pipe finished product, and setting a determined dimension, so as to obtain the final product. According to the method, the employed alloy material is used to manufacture a proper square or rectangular pipe which is cut into a needed length for usage, the method helps to greatly facilitate manufacturing of electronic devices, save raw materials (the utilization rate reaches 90% or more), reduce the cost and improve the production efficiency, and can satisfy large-batch production.
Description
Technical field
The present invention relates to a kind of processing method of shape tube material, be specially a kind of processing method of ferronickel mild steel teleoseal shape tube material.
Background technology
Expansion alloy can carry out mating the metal material of sealed knot with glass or pottery.Its general types comprises:
1, iron-nickel-cobalt system, main chemical compositions: Ni(15%-40%), Co(5%-25%) and, surplus is Fe.
2, iron-nickel system, Ni(15%-50%), surplus is Fe.Also have other elements a small amount of, as: C, Mn, Si, P, S, Cr, Cu, concrete visual standard GB/T5231-2005.
3, mild steel system, as 10# steel.
The moulding materials such as chip carrier, optical transmitter module carrier and high power laser shell in electronic device mainly mainly developed by these materials.Be mainly used in Aeronautics and Astronautics, electronics, microwave, laser, communication, radar, the contour reliable electronic equipment of weapons and industrial circle; For metal glass envelope or porcelain sealing-in plug-in unit, electronics shell etc.The shape of described connector is mostly square or rectangular; Specification from 3 × 5mm ~ 100 × 200mm, numerous in variety.
---Linear cut outer rim---Linear cut interstitial hole---becomes frame body to traditional diamond-making technique: sheet material flat surface grinding take the altitude; Its stock utilization is less than 50%, and processing cost high efficiency is low, is not suitable for producing in enormous quantities; Linear cut efficiency low velocity is slow, and processing cost is high again, should not produce in a large number; In addition, by the waste of material in framework, cost is very high, because the expansion alloy of electronic connector contains the elements such as Ni, Co, is that country accounts for slightly stockpile.
Summary of the invention
The object of the present invention is to provide a kind of easy to process, save material, cost is low and the processing method of the ferronickel mild steel teleoseal shape tube material that production efficiency is high.
For achieving the above object, the invention provides following technical scheme:
A processing method for ferronickel mild steel teleoseal shape tube material, concrete steps are:
(1) raw metal is smelted in a vacuum furnace by necessary requirement composition, then cast alloy pig after electroslag furnace is purified;
(2) alloy pig is made bar after repeatedly forging, forging temperature is 1000-1200 DEG C, then by Surface of Rod Bar car light and can not defectiveness;
(3) pipe is bored a hole in bar hot-working;
(4) pickling is carried out to pipe, remove surface oxide layer;
(5) by cold rolling for pipe one-tenth pipe;
(6) carry out annealing in process to the pipe after cold rolling, remove machining stress, annealing temperature controls at 800-900 DEG C, and is incubated 0.5-1.5h;
(7) repeatedly step (4), step (5) and step (6);
(8) by orthogonal for pipe cold drawing pipe; Make foreign side's mould and Nei Fangmo during cold drawing rectangular tube, control chamfer dimesion, by foreign side's mould, pipe is drawn into rectangular tube;
(9) by shaping for rectangular tube drawing; Use foreign side's mould and Nei Fangmo to coordinate and rectangular tube is drawn into the rectangular tube finished product with design wall thickness and chamfering;
(10) correct linearity and the depth of parallelism of rectangular tube finished product, after sizing, namely obtain final finished.
As the further scheme of the present invention: in step (2), forging temperature is 1100 DEG C.
As the further scheme of the present invention: the acid adopted in step (4) is the mixed acid of nitric acid and hydrofluoric acid.
As the further scheme of the present invention: in step (6), annealing temperature controls at 850 DEG C, and is incubated 1h.
Compared with prior art, the invention has the beneficial effects as follows: alloy material used is manufactured suitable square or rectangle pipe material by the present invention, is cut into required length during use; Greatly facilitate the manufacture of electronic device, save material (utilization rate reaches more than 90%), reduces cost, improve production efficiency, can meet production in enormous quantities.
Detailed description of the invention
