Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is the temperature control method of the radial precision forging titanium or titanium alloy bar of a specific embodiment of the invention
Flow diagram.
In a specific embodiment, the temperature control method of radial precision forging titanium or titanium alloy bar provided by the invention, can
Suitable for diameter 100mm~300mm range bar forging, comprising the following steps:
S1: blank heating.
Before radial precision forging, first by blank heating, bar temp is homogenized, refine crystal grain, improves the property of finish forge bar
Energy.Specifically, blank shove charge starts timing heat preservation when furnace temperature reaches 860~900 DEG C after then furnace temperature rises to 860~900 DEG C,
And soaking time is calculated with sotck thinkness, every 1mm thickness increases by 0.8~1.5min soaking time.It should be noted that above-mentioned each
Numberical range is that preferred parameter range can be used corresponding in last each parameter area for a certain determining process
Parameter value is controlled.
S2: by the blank after heating using radial precision forging machine carry out unilateral side forge, forge frequency range be 90~180 times/
Min, the feed speed range of blank is 1.5~3m/min, and the starting forging temperature of radial precision forging machine is not more than 850 DEG C, monitoring forging
Forging forges the temperature of end during beating, and when temperature is greater than preset temperature, carries out air-cooled until temperature is reduced to default temperature
Continue to forge after degree, the range of preset temperature is 820~850 DEG C.It should be noted that herein and the unilateral forging that is mentioned below
It beats, refers to and only unidirectionally forged in a direction by axial one end of bar to another extreme direction, such as by the axial ends of bar point
It is not denoted as the side A and the side B, then it can be to be forged by the side A to the side B that unilateral side, which forges,.It is forged by unilateral side, avoids part and generate height
Temperature makes forging equalizing temperature, refines crystal grain, improves performance.The raising of transverse direction and longitudinal direction temperature uniformity when forging forges is protected
The uniformity of forging transverse direction and longitudinal direction performance is demonstrate,proved.
During forging, it is 90~180 times/min that control, which forges frequency range, keeps forging for a upper frequency.
The starting forging temperature of radial precision forging machine is not more than 850 DEG C, and during forging, and forging forges the temperature of end during monitoring forges
Degree, when temperature is greater than preset temperature, progress is air-cooled to be continued to forge after temperature is reduced to preset temperature, the model of preset temperature
Enclose is 820~850 DEG C.It should be noted that forging end as temperature monitoring region using forging, end herein refers to forging reality
When forge the end of position, the i.e. corresponding a certain range of region of precise forging machine tup, such as the corresponding 500mm model of precise forging machine tup
It encloses.By the temperature monitoring in forging process, only technique is allowed to refer between 750~850 DEG C forging temperature control always
Determine temperature spot to forge, to improve the uniformity of temperature when forging forges.Preset temperature can specifically appoint in 820~850 DEG C
Meaning numerical value, in order to guarantee to forge temperature no more than 850 DEG C, preset temperature can be set to 820 DEG C, 830 DEG C or 840 DEG C etc..
Since the pyroconductivity of titanium or titanium alloy is lower, it is uneven that water cooling will cause bar internal and external temperature, influences performance matter
Amount, therefore in the application by the way of air-cooled, further increase the temperature uniformity of bar transverse direction and longitudinal direction.
The feed speed range of blank is 1.5~3m/min, advantageously ensures that the forging surface temperature of titanium or titanium alloy not
It obtains and is higher than 850 DEG C, further ensure that and control forging process temperature between 750~850 DEG C always, to guarantee titanium or titanium alloy
Crystal grain refinement guarantees the high intensity and high-ductility of forging material.
S3: after the completion of forging per pass, airway time returns to starting point, and return step S2 carries out unilateral side and forges, until forging
Knotting beam.Namely when being forged to one passage of the side B completion after forging by the side A as described above, airway time returns to starting point,
The side A is returned to, then carries out forging for lower a time according to the control parameter in S2 in step, until forging end.
Using the temperature control method of radial precision forging titanium or titanium alloy bar provided by the invention, blank heating is first carried out, then
Blank after heating is carried out unilateral side to forge, and it is 90~180 times/min, the feed speed model of blank that control, which forges frequency range,
It encloses for 1.5~3m/min, and the starting forging temperature of radial precision forging machine is not more than 850 DEG C, forging forges end during monitoring forges
Temperature, when temperature be greater than preset temperature when, carry out it is air-cooled until temperature be reduced to preset temperature after continues to forge, preset temperature
Range be 820~850 DEG C.By Forging Equipment Speed, the forging and stamping frequency, the state modulator for forging direction, the type of cooling, so that bar
Temperature is in 750~850 DEG C of temperature range section always, ensure that the temperature of bar precision forging process transverse direction and longitudinal direction is uniform
Property, and then ensure that the uniformity of bar transverse direction and longitudinal direction performance.And the temperature control method is used, by controlling technological parameter, energy
Effective controlled forge process pressure, makes forging force be less than the maximum pressure of precise forging machine.It can be effectively controlled pieces of bar stock temperature, make bar temperature
Degree homogenization, refines crystal grain, improves the performance of finish forge bar, improves mirco structure.This method is suitable for production diameter of rod
The titanium or titanium alloy bar of 100mm~300mm, bar length about 2~18m improve lumber recovery.
Further, step S3 is specifically included:
After the completion of every a time forges, airway time returns to starting point and air-cooled 90~300s, and then return step S2 is carried out
Unilateral side forges, until forging end.After the forging of every a time, return to initial point and simultaneously control air cooling time, time control 90~
300s, specific air cooling time can be adjusted according to forging temperature, and general control drops at a temperature of may make in above-mentioned time range
To 850 DEG C hereinafter, guaranteeing the temperature uniformity of bar transverse direction and longitudinal direction.
Specifically, forging forges the temperature of end during monitoring forges in above-mentioned steps S2, specifically include:
The temperature of end is forged during forging every preset time detection forging.By detecting forging every preset time
The temperature of end is forged, can both monitor and forge temperature, the ease of operation can also be taken into account.It as needed, can also be real
When monitoring forging forge the temperature of end.Preset time is specifically as follows 10s, specifically, detection forging forges the temperature of end,
