the method for determining the expansion amount of the tool comprises the following steps:
before the tool enters the furnace along with a casting, the inner conical ring needs to move downwards by screwing the bolt, so that the outer conical ring is expanded to be close to the inner side of the cylinder, and the purpose of correcting the shape of the cylinder is achieved. The size of the inner diameter of the casting after the shape correction is directly influenced by the outer diameter of the expanded tool.
In order to calibrate the inner diameter of the casting cylinder to the theoretical size D0, the calibration tool needs to be expanded to D work at normal temperature, and assuming that the tool is completely close to the casting inner cavity at the time, namely the casting inner diameter D piece is D work, after the casting inner diameter D piece is heated to T height (730 ℃) along with a furnace and cooled to room temperature T room (20 ℃), the D0 and the D work meet the following conditions:
d work + delta D work-delta D piece as D0 formula (1)
Wherein the delta D is the diameter increase value of the tool when the tool is heated and expanded, and the delta D is the diameter increase value of the casting when the casting is heated and expanded. According to a calculation formula of the thermal expansion amount:
delta D I ═ D I alpha steel (Tgao-T chamber) formula (2)
Δ D piece ═ D piece α Ti (Tgao-Tchamber) formula (3)
Wherein alpha Ti is the thermal expansion coefficient of the titanium alloy and is 10.1 multiplied by 10 < -6 >/DEG C; the thermal expansion coefficient of the alpha steel is 45# steel and is 15.0 multiplied by 10 < -6 >/DEG C.
Substituting the numerical values of the formulas (2) to (3) and the numerical values of the alpha Ti and the alpha steel into the formula (1) to obtain the following formula:
aiming at a cylindrical structure of an inner cavity of the cylinder, the diameter of the theoretical inner cavity is 429.6mm, the single side of the theoretical machining allowance is 3mm, according to the delivery requirement, the inner and outer machining allowances of the casting cylinder are at least 1mm on the single side, namely the inner diameter of the casting cylinder is 425.6-433.6mm, and the diameter of the tool before entering and leaving the furnace is 424.1-432.1 mm according to a formula (4);
and 4, after the shape correcting device is installed, putting the shape correcting device and the workpiece 11 to be corrected into a heating furnace, heating to 730 +/-10 ℃, preserving heat for 1.5-2.5 hours, cooling to below 250 ℃ along with the furnace, and discharging to finish the shape correction of the workpiece 11 to be corrected.
After the shape correction of the three-dimensional laser scanner, most of the machining allowance of the outer side of the detection cylinder body is 2mm, and the lowest point is 1.5mm, so that the subsequent machining requirement is met.
And (3) correcting the shape of the casting by applying force to the tool outside the furnace when the shape correcting workpiece is at normal temperature, and only ensuring that the casting is subjected to creep deformation when heating, fixing the shape and eliminating stress, so that the shape correcting of the casting adopts a conventional annealing system, namely heating to 730 +/-10 ℃, preserving heat for 1.5-2.5h, and discharging the casting after cooling to below 250 ℃ along with the furnace. At the moment, the casting is subjected to creep deformation through stress annealing, the shape is fixed, the roundness and the profile degree of a deformation area of the casting are effectively controlled through tool shape correction and heating treatment, and the designed shape is recovered by adopting a mechanical correction and heating treatment method.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
