Abstract
The invention discloses a processing method of a ferronickel low-carbon fernico special-shaped pipe material. The processing method of the ferronickel low-carbon fernico special-shaped pipe material particularly comprises the following steps: forging an alloy ingot for multiple times to prepare a bar material; carrying out hot processing and punching on the bar material to produce a pipe blank; pickling, carrying out cold rolling on and annealing the pipe blank, carrying out cold drawing on a circular pipe after repeating for multiple times to form a rectangular pipe; drawing and molding the rectangular pipe; correcting the linearity and the parallelism depth of a rectangular pipe finished product, and carrying out scaling-off to form a finished product. The alloy material is used for manufacturing an appropriate square or rectangular pipe, and the pipe is cut into the required length in use; electronic devices can be manufactured conveniently, and raw materials are saved (the utilization ratio reaches 90% above); the cost is reduced; the production efficiency is improved; the volume production can be met.
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 is the metal material that can mate with glass or pottery sealed knot.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 a small amount of other elements, as: C, Mn, Si, P, S, Cr, Cu, concrete visible standard GB/T5231-2005.
3, mild steel system, as 10# steel.
These materials are mainly chip carrier, optical transmitter module carrier and the moulding materials such as shell for high power laser in development electronic device.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 is from 3 × 5mm～100 × 200mm, numerous in variety.
---line cutting outer rim---line cutting 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; Line cutting 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 that electronic connector is used contains the element 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, the processing method of cost is low and production efficiency is high ferronickel mild steel teleoseal shape tube material.
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 vacuum drying oven by necessary requirement composition, then cast alloy pig after electroslag furnace is purified;
(2) alloy pig is made to bar after repeatedly forging, forging temperature is 1000-1200 DEG C, then by Surface of Rod Bar car light and can not defectiveness;
(3) bar hot-working is bored a hole into pipe;
(4) pipe is carried out to pickling, remove surface oxide layer;
(5) by cold rolling pipe one-tenth pipe;
(6) pipe after cold rolling is carried out to annealing in process, remove machining stress, annealing temperature is controlled at 800-900 DEG C, and is incubated 0.5-1.5h;
(7) repeatedly step (4), step (5) and step (6);
(8) by orthogonal pipe cold drawing pipe; When cold drawing rectangular tube, make foreign side's mould and Nei Fangmo, control chamfer dimesion, by foreign side's mould, pipe is drawn into rectangular tube;
(9) by rectangular tube drawing moulding; Use foreign side's mould and Nei Fangmo to coordinate rectangular tube is drawn into the rectangular tube finished product with design wall thickness and chamfering;
(10) linearity and the depth of parallelism of correction rectangular tube finished product, obtain final finished after sizing.
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 adopting 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 is controlled 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 needed length when use; Greatly facilitate the manufacture of electronic device, save material (utilization rate reaches more than 90%), has reduced cost, has improved production efficiency, can meet production in enormous quantities.
Detailed description of the invention
