Abstract
The invention relates to a manufacturing process method for high-temperature alloy biscuits. The process method includes the steps that a blank is heated to the required temperature of 1000-1140 DEG C, high-temperature cotton and a binder are adopted for coating after the blank is discharged from a furnace, and the blank is melted and subjected to heat preservation for 30 min; and a biscuit blank is upset to deform by 30%-70% of the deformation firstly, and the blank is overturned within 15 seconds, placed at the center of a forming die and continues to be upset to the height required by the process method. The biscuits manufactured according to the process requirements are small and uniform in grain size, and the process method is suitable for final die forging of engine disc type workpieces.
Description
Technical field：
The invention belongs to high temperature alloy technical field of hot working, is related to a kind of high temperature alloy biscuit forging
Make method.
Background technology：
High temperature alloy belongs to difficult deformation special alloy, and resistance of deformation is big, and malleable temperature range is narrow,
High temperature alloy major applications are in aero-engine diskware.The general manufacturing process of diskware is for first
Biscuit processed, then carries out die forging, and biscuit is most important for the forging part tissue effect of output.
At present, traditional upsetting cake method, belongs to flat-die forging, and profile has bulge, there is local and becomes
Shape is little, and blank belongs to exposed, and forging process temperature reduces phenomenon faster；Biscuit is caused to occur
Small deformation area is larger with the grain size extreme difference in large deformation area, or even mixed crystal, while local still retains
The situation of the original structure of bar.Affected by original biscuit tissue, manufactured by follow-up die forging,
The general structural homogenity of diskware of output is also poor, there is big crystal grain situation, has had a strong impact on boat
The service life of empty electromotor diskware.The problem has become the master of aero-engine diskware presence
Problem is wanted, as biscuit organizes most important for final diskware tissue effect, in certain type machine disk
In part manufacture specific technique tackling key problem, it is specifically designed for biscuit manufacture and expands series of studies, it was found that
This optimization biscuit method processed.
The present invention adopts the details controls such as loose tool, process upset to improve by heating jacket, upsetting cake
The base effect of high temperature alloy, improves the structural homogenity and its service life of diskware.
The content of the invention：
The technical problem to be solved is：The present invention is adopted by heating jacket, upsetting cake
The details controls such as loose tool, process upset improve the base effect of high temperature alloy, improve diskware
Structural homogenity and its service life.
The technical scheme is that：
A kind of forging method of high temperature alloy biscuit, comprises the following steps,
Step 1：By blank heating to technological requirement temperature, preheating before high-temperature heating area, is provided with
Step, high-temperature holding time are come out of the stove with high temperature cotton jacket to after, and are melted down；
Step 2：Blank melts down post-heating to technological requirement temperature 30-50 minutes, comes out of the stove and turns
Move to forging equipment；
Step 3：Upsetting cake first is to the 30% to 70% of deflection；
Step 4：Blank turn-over is completed in 15 seconds and loose tool center is positioned over, continues upsetting to technique
Require height.
Detailed technology scheme is as follows
A kind of high temperature alloy biscuit method of manufacturing technology, i.e., first by blank heating (1000～
1140 DEG C) it is incubated according to the heat insulating coefficient of the alloy, come out of the stove to temperature and jacket melt down, Ran Houjin
Stove heat is come out of the stove after insulation 30min, is transferred to forging equipment and starts to former technological requirement temperature
The half of jumping-up, first jumping-up to technological requirement biscuit height, then by blank turn-over and places
In loose tool center, continue forging and stamping, until technological requirement height.
It is stressed that：Loose tool is designed according to the final external diameter and height dimension of biscuit,
Aided in draft angle so that final biscuit is easy to loose tool；
The invention has the beneficial effects as follows：The present invention adopts loose tool, mistake by heating jacket, upsetting cake
The details control such as journey upset improves the base effect of high temperature alloy, and the tissue that improve diskware is equal
Even property and its service life.
Specific embodiment：
GH4169 alloy bars are chosen below, and the process step of the invention is carried out specifically
It is bright.
Existing bar specificationOne, raw material reviews 6 grades of grain size, is used for
Manufacture diskware biscuit be highlyFollowing steps are formulated according to this method.
The first step is first by GH4169 alloy barsIt is heated to technological requirement temperature
1010 DEG C of degree, is incubated 132min, comes out of the stove with high temperature cotton jacket；
The bar of jacket is melted down and continues to be heated to 1010 DEG C of technological requirement temperature by second step, is protected
Warm 30min, comes out of the stove and is transferred to forging equipment；
It is 150 that 3rd step calculates the half of upsetting cake height of drop, and upsetting cake first is to 350
(500-150)。
4th step is positioned over loose tool center rapidly by blank turn-over, and continuing upsetting cake will to technique
Seek height.
Control through above forging process, the biscuit for obtaining is taken not in level and two direction of diameter
It is, between 7～8 grades, to increase relative to bar original grain degree with the grain size of position, and
It is satisfied with die forging requirement.
