Abstract
The invention discloses a kind of novel flange forging stock production technology, the production technology of the flange forging stock includes the following steps：A, after the blanking of raw material pole, into being heated in electric furnace, using four stage heating means, first stage heating temperature is 800 825 DEG C, and the time is 12 15s；Second stage heating temperature is 930 960 DEG C, and the time is 25 28s；Phase III heating temperature is 840 860 DEG C, and the time is 15 17s；Fourth stage heating temperature is 720 740 DEG C, and the time is 28 31s.The present invention first carries out heating for multiple times cooling processing so that raw material pole surface and internal performance are uniform in the flange forging stock stage to raw material pole so that postorder extrusion forming is more stablized；By multiple solution heat treatment, the grain structure of forging stock is uniform, hardness is low, good toughness, surrender degree is high, tension is strong, elongation percentage reaches requirement, and flange forging stock efficiency improves 300%, and material can accomplish zero loss.
Description
Technical field
The present invention relates to flange technical field, specially a kind of novel flange forging stock production technology.
Background technology
Flange is important conduit coupling, is widely used.Currently, flange is in the fabrication process, typically pole blanking
Afterwards, it directly machines（Lathe process, milling machine processing etc.）It forms, but such processing method is with turning, milling time are long, labor
Dynamic cost is big and spillage of material is very serious, accounts for 40%-50%.Due to prolonged deep processing, the residual stress of product is more, material
The hardness of material is high, directly affects the mechanical property and performance of material.
The step of needing to carry out flange raw material forging stock in flange production process, and adding during present flange forging stock
It needs the heating for carrying out different temperatures to it to carry out quenching treatment in thermal process, and needs needs pair during flange forging stock
Temperature and flange forging stock time are effectively controlled, for this purpose, it is proposed that a kind of novel flange forging stock production technology.
Invention content
The purpose of the present invention is to provide a kind of novel flange forging stock production technologies, are asked with solve to propose in background technology
Topic.
To achieve the above object, the present invention provides the following technical solutions：A kind of novel flange forging stock production technology, the method
The production technology of blue forging stock includes the following steps：
A, after the blanking of raw material pole, into being heated in electric furnace, using four stage heating means, first stage heating temperature
It is 800-825 DEG C, time 12-15s；Second stage heating temperature is 930-960 DEG C, time 25-28s；Phase III adds
Hot temperature is 840-860 DEG C, time 15-17s；Fourth stage heating temperature is 720-740 DEG C, time 28-31s；
B, the raw material pole after heating is put into forging of punching machine into required flange shape after being cooled to room temperature；
C, it and then places into friction press, it is cold extrusion shaped to flange basic size on mold；Again through solution heat treatment,
Form flange blank.
The present invention first carries out heating for multiple times cooling processing so that raw material pole table in the flange forging stock stage to raw material pole
Face and internal performance are uniform so that postorder extrusion forming is more stablized；Pass through multiple solution heat treatment, the grain structure of forging stock
Uniformly, hardness is low, good toughness, surrender degree is high, tension is strong, elongation percentage reaches requirement, and flange forging stock efficiency improves 300%, material energy
Accomplish zero loss.
