Abstract
A kind of copper mold forges manufacturing process, including terne metal raw material melting, while being prepared to mould and pre- heat sealing die；Copper water is poured into a mould；Pressure；The steps such as die sinking pickup are poly-.Liquid easily flows into the characteristics of describing easy when the present invention is using metal casting, with reference to hot forging technology, make molten metal flowing forming in mold cavity, and under larger static pressure effect crystallization and freezing, and produce plastic deformation, the shrinkage cavity because metal liquid is shunk, solidification shrinkage is formed and shrinkage porosite are forcibly eliminated, to obtain the various Melted Metal Squeezing Workpieces without any casting flaw.Beneficial effect：The defect that casting technique generation can be eliminated improves product mechanical strength, and can produce the product of the complex geometric shapes that contour forging technique cannot be processed, therefore not only increases the performance of product, and it is larger reduce energy consumption, saved the energy.
Description
Technical field
It is more particularly to a kind of to forge manufacturing process for the copper mold that copper is just processed the present invention relates to a kind of copper mold forging manufacturing process, belong to the technical field of machining.
Background technology
At present, electrified high-speed railway elements of contacting net product is generally manufactured using casting technique or metal contour forging technique, and the product produced using casting technique easily produces shrinkage cavity and porosity, microstructure coarsening, and defect is more, it is unfavorable for the raising of mechanical strength, it is impossible to ensure the traffic safety requirement of bullet train；And the product of some more complicated geometries cannot be completed using contour forging technique production, and energy resource consumption is larger.
The content of the invention
The technical problem to be solved in the present invention is：In order to overcome above-mentioned technical problem, there is provided a kind of copper mold for electrified high-speed railway elements of contacting net forges manufacturing process, the defect that can eliminate casting technique generation improves product mechanical strength, and can produce the product of complex geometric shapes.
A kind of copper mold forges manufacturing process, and specific contour forging technique step is as follows：
A) melting of terne metal raw material, while be prepared to mould and preheated；
B) matched moulds；
C) copper water cast；
D) press；
E) pickup is molded.
Described melting is comprised the following steps：
A) preparation before melting；
B) feed；
C) heating fusing；
D) copper water refining；
E) detection, adjusting component；
F) furnace temperature is adjusted；
G) heat preservation for standby use.
The cast includes slow shot and fast shot, and slow shot pressure is 12 MPas, and slow shot speed is 0.2-0.4 metre per second (m/s)s；Fast shot speed is 0.8-1 metre per second (m/s)s；Whole shot time is 6-8 seconds；The time for keeping pressure is 12-14 seconds.Copper water pouring temperature：660℃ ；Mold preheating temperature：180℃ ；The continuous operating temperature of mould：200-220℃.
The copper water refining temperature is 750 DEG C, copper water refining time：15 minutes.
Beneficial effect：The defect that casting technique generation can be eliminated improves product mechanical strength, and can produce the product of the complex geometric shapes that contour forging technique cannot be processed, therefore not only increases the performance of product, and it is larger reduce energy consumption, saved the energy.

Copper mold forging manufacturing process is the compound of foundry engieering and hot forging technology.Liquid easily flows into the characteristics of describing easy when the present invention is using metal casting, with reference to hot forging technology, make molten metal flowing forming in mold cavity, and under larger static pressure effect crystallization and freezing, and produce plastic deformation, the shrinkage cavity because metal liquid is shunk, solidification shrinkage is formed and shrinkage porosite are forcibly eliminated, to obtain the various Melted Metal Squeezing Workpieces without any casting flaw.Therefore Melted Metal Squeezing Workpieces are compared with casting, it is easy to eliminate casting flaw；Compared with hot mould-forging piece, shaping is easy, and required plastic force is small, i.e. the strong point of process makes full use casting technique and hot-die forging process is made in copper mold forging, while also compensate for the deficiency of both techniques.The elements of contacting net product manufactured using terne metal liquid forging process has casing seat, sleeve ears, sleeve pipe monaural, rotation ears, positioning pipe ears, positioning support, Messenger Wire base etc..
Liquid forging equipment has vertical and horizontal type structure form.The material trademark for using the elements of contacting net product of terne metal liquid forging process manufacture is AlSi7Mg0.3 and AlSi7Mg0.6；Copper water refining temperature：750℃ ；Copper water refining time：15min ；Copper water pouring temperature：660℃ ；Mold preheating temperature：180℃ ；The continuous operating temperature of mould：200~220 DEG C；Slow shot pressure
：12Mpa ；Slow shot speed：0.2~0.4m/s；Fast shot speed：0.8~1.0m/s；Shot time：6~
8s ；Dwell time：12~14s.
