DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] In one embodiment, a die design method for a horizontal forging assembly blank of a high-temperature alloy blade is provided, and the die design is performed using three-dimensional software, which may be, but is not limited to, PRO / E and SolidWorks.

[0044] The die design method for the horizontal forging aggregate blank of the high-temperature alloy blade of this embodiment includes the following steps:

[0045] S1. Construct a target horizontal forging aggregate model according to a target blade model. The target horizontal forging aggregate model includes a blade tip horizontal forging aggregate portion 100 , a blade body horizontal forging aggregate portion 110 and a blade root horizontal forging aggregate portion 120 .

[0046] Wherein, constructing a target horizontal forging aggregate model according to the target blade model comprises the following steps:

[0047] S11. constructing a target blade forging model according to the target blade model.

[0048] Specifically, the target blade forging model is constructed from the target blade model according to different die forging requirements, for example, the target blade forging model is obtained after the blade forging blank is converted by keeping the precision forging part unchanged and increasing the remaining part by 2 mm on one side. The conversion process is well known to those skilled in the art and will not be described in detail here.

[0049] S12. Select several different cross sections axially on the target blade forging model and calculate the area of ​​each cross section.

[0050] It should be noted that the number of sections is equal to the ratio of the axial length of the target blade forging model to ΔL, 3 mm ≤ ΔL ≤ 5 mm.

[0051] S13, converting each cross section into a circle with equal area and sequentially combining the circles axially to form a target horizontal forging aggregate model.

[0052] According to the segments of the blade tip, blade body and blade root of the target blade, the blade tip horizontal forging gathering part 100, the blade body horizontal forging gathering part 110 and the blade root horizontal forging gathering part 120 are divided into equal axial lengths on the target horizontal forging gathering part model.

[0053] S2. Determine the size of the blanking part model based on the target horizontal forging aggregate part model and divide the blanking part model into a blade tip blanking part, a blade body blanking part and a blade root blanking part.

[0054] Among them, the blanking part model is cylindrical, and the volumes of the blade tip blanking part, the blade body blanking part and the blade root blanking part are respectively equal to the volumes of the blade tip horizontal forging gathering part 100, the blade body horizontal forging gathering part 110 and the blade root horizontal forging gathering part 120.

[0055] Specifically, the size of the blank model is based on the axial diameter of the blade body horizontal forging gathering part 110 of the target horizontal forging gathering part model as the blank diameter, and the length of the blank is based on the volume of the target horizontal forging gathering part model and the axial diameter of the blade body horizontal forging gathering part 110 using the cylindrical volume formula.

[0056] S3. After constructing the blade tip blanking part of the blanking part model into a structure with the same shape and size as the blade tip horizontal forging gathering part 100, a blade tip horizontal forging gathering part model is obtained, and horizontal forging parameters are added to the blade tip horizontal forging gathering part model to obtain the shape of the forging hole 210 of the blade tip horizontal forging gathering part blank.

[0057] The horizontal forging parameters are increased to increase the thermal coefficient and draft angle, specifically, the size of the blade tip horizontal forging aggregate model is expanded based on the thermal coefficient. The reason for increasing the thermal coefficient is that the material needs to be heated during the process of placing the blank or aggregate into the die forging, and the size of the aggregate will increase after heating.

[0058] S4. Determine whether the blade root blanking part on the blade tip horizontal forging aggregate model meets the first rule of horizontal forging local upsetting. If so, add horizontal forging parameters to the target horizontal forging aggregate model to obtain the shape of the target horizontal forging aggregate blank forging hole 410; otherwise, proceed to the next step.

[0059] Whether the first rule of horizontal forging local upsetting is satisfied refers to whether the ratio of the length and diameter of the blade root blanking part is less than 3. If so, the first rule of horizontal forging local upsetting is satisfied.

[0060] S5. Adjust the partial volume of the blade root blanking part on the blade tip horizontal forging aggregate model to remain unchanged, increase the shaft diameter by M times, obtain the intermediate horizontal forging aggregate model, add horizontal forging parameters to the intermediate horizontal forging aggregate model to obtain the shape of the forging hole 310 of the intermediate horizontal forging aggregate blank, and use the intermediate horizontal forging aggregate model as the new blade tip horizontal forging aggregate model and then return to step S4 until the blade root blanking part on the new blade tip horizontal forging aggregate model meets the first rule of horizontal forging local upsetting and then enter the next step.

[0061] When the ratio of the length and diameter of the blade root blanking part is greater than 3, due to the limitations of the forging machine or materials, the blade root horizontal forging aggregate shape cannot be formed in one forging, so multiple forgings are required.

[0062] Specifically, 1.10≤M≤1.25.

[0063] S6. Prepare a sub-die based on the shape of the forging hole of each blank, and all the sub-dies constitute a die set for horizontal forging of the aggregated blank.

[0064] The die design method for the horizontal forging assembly blank of the high-temperature alloy blade of the present embodiment can design sub-dies for each forging step from the blank to the horizontal forging assembly blank. The shape of the forging hole of each sub-die blank is the same as the shape and size finally generated by the forging step. Therefore, the use of the above-mentioned sub-dies for each forging step will not generate waste, thereby simplifying the forging steps.

[0065] Among them, the punching hole of the sub-die prepared based on the shape of the forged hole 210 of the blade tip horizontal forging aggregation piece blank is coaxially arranged with the first punch accommodating hole 200 and the forged hole 210 of the blade tip horizontal forging aggregation piece blank in sequence, and the blade tip end of the forged hole 210 of the blade tip horizontal forging aggregation piece blank is connected to the first punch accommodating hole 200; the punching hole of the sub-die prepared based on the shape of the forged hole 310 of the intermediate horizontal forging aggregation piece blank is coaxially arranged with the first rear top accommodating hole 300 and the forged hole 310 of the intermediate horizontal forging aggregation piece blank in sequence, and the intermediate horizontal forging aggregation piece blank One end of the blade tip of the forging hole 310 is connected to the first rear top position accommodating hole 300; the stamping hole of the sub-mold prepared based on the shape of the target horizontal forging aggregate model blank forging hole 410 is coaxially arranged with the second rear top position accommodating hole 400, the target horizontal forging aggregate model blank forging hole 410 and the second punch accommodating hole 420 in sequence, the blade tip end of the intermediate horizontal forging aggregate model blank forging hole 310 is connected to the second rear top position accommodating hole 400, and the blade root end of the intermediate horizontal forging aggregate model blank forging hole 310 is connected to the second punch accommodating hole 420.

[0066] The lengths of the punch receiving hole and the rear ejection receiving hole can be specifically set according to different materials.

[0067] In addition, the mold set prepared by the method of this embodiment is handed over to a foundry for preparation, and then the subsequent preparation is prepared by the company, which can shorten the preparation cycle of the company. In the process of shortening the preparation cycle, the final blade structure can be protected from being disclosed, thereby protecting the technical secrets.

[0069] Specifically, the upper mold and the lower mold of each sub-mold are provided with fastening components that can be matched and installed.

[0070] In a specific embodiment, the design raw material grade is Inconel 718, the standard is AMS 5662, and the finish is Ra 0.40 (μm).

Figure 5 The A blade horizontal forging assembly model is shown.

[0074] (3) Calculate the volume of the A blade horizontal forging aggregation model, take the axial diameter of the blade horizontal forging aggregation part 110 of the A blade horizontal forging aggregation model as the diameter, and take the ratio of the volume of the A blade horizontal forging aggregation model to the axial diameter of the blade horizontal forging aggregation part 110 as the length to construct the following: Figure 6 The blanking model shown in the figure has chamfers of C1.0 to C1.5 at both ends.

[0075] (4) The tip blanking part of the blanking part model is constructed into a structure with the same shape and size as the tip horizontal forging gathering part 100 to obtain the following Figure 7 The blade tip horizontal forging aggregate model shown is adjusted to increase the overall size of the blade tip horizontal forging aggregate model by 1.012 times and add a draft angle to obtain the shape of the forging hole 210 of the blade tip horizontal forging aggregate blank.
