Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] In one embodiment, a die design method of a high-temperature alloy blade's upsetting cluster blank is provided, which is designed by using a three-dimensional software, which can be but is not limited to PRO / E and SolidWorks.

[0044] The die design method of the high-temperature alloy blade's upsetting cluster blank of the embodiment comprises the following steps:

[0045] S1, a target upsetting cluster model is constructed according to a target blade model, the target upsetting cluster model comprising a blade tip upsetting cluster part 100, a blade body upsetting cluster part 110 and a blade root upsetting cluster part 120.

[0046] The target upsetting cluster model is constructed according to the target blade model, comprising the following steps:

[0047] S11, a target blade forging model is constructed according to the target blade model.

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

[0049] S12, a plurality of different cross sections are selected axially on the target blade forging model and the areas of the cross sections are calculated.

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

[0051] S13, each cross section is converted into a circle with equal area and each circle is combined axially in sequence to form the target upsetting cluster model.

[0052] The blade tip upsetting cluster part 100, the blade body upsetting cluster part 110 and the blade root upsetting cluster part 120 are divided axially in equal length on the target upsetting cluster model according to the blade tip, the blade body and the blade root of the target blade.

[0053] S2, the size of a blank model is determined based on the target upsetting cluster model and the blank model is divided into a blade tip blank part, a blade body blank part and a blade root blank part.

[0054] The blank model is cylindrical, and the volumes of the blade tip blank part, the blade body blank part and the blade root blank part are equal to the volumes of the blade tip upsetting cluster part 100, the blade body upsetting cluster part 110 and the blade root upsetting cluster part 120, respectively.

[0055] Specifically, the size of the blanking piece model is set as the shaft diameter of the blade body lying forging aggregation part 110 of the target lying forging aggregation piece model as the diameter of the blanking piece, and the length of the target lying forging aggregation piece model and the shaft diameter of the blade body lying forging aggregation part 110 calculated by the cylinder volume formula as the length of the blanking piece.

[0056] S3, the blade tip blanking part of the blanking piece model is configured as a structure with the same shape and size as the blade tip lying forging aggregation part 100 to obtain a blade tip lying forging aggregation piece model, and the lying forging parameters are added to the blade tip lying forging aggregation piece model to obtain the shape of the blade tip lying forging aggregation piece rough forging hole 210.

[0057] The lying forging parameters are the increase of the thermal coefficient and the draft angle, and specifically, the size of the blade tip lying forging aggregation piece model is overall enlarged based on the thermal coefficient. The reason for increasing the thermal coefficient is that the material needs to be heated during the process of putting the blanking piece or the aggregation piece into the mold for forging, and the size of the aggregation piece will increase after heating.

[0058] S4, it is judged whether the blade root blanking part on the blade tip lying forging aggregation piece model satisfies the lying forging local upsetting first rule, if yes, the lying forging parameters are added to the target lying forging aggregation piece model to obtain the shape of the target lying forging aggregation piece rough forging hole 410; otherwise, the next step is entered.

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

[0060] S5, the part of the volume of the blade root blanking part on the blade tip lying forging aggregation piece model is adjusted to be unchanged, and the shaft diameter is increased by M times to obtain an intermediate lying forging aggregation piece model, the lying forging parameters are added to the intermediate lying forging aggregation piece model to obtain the shape of the intermediate lying forging aggregation piece rough forging hole 310, and the intermediate lying forging aggregation piece model is taken as a new blade tip lying forging aggregation piece model, and then the step S4 is returned until the blade root blanking part on the new blade tip lying forging aggregation piece model satisfies the lying forging local upsetting first rule and then the next step is entered.

[0061] When the ratio of the length and the diameter of the blade root blanking part is greater than 3, due to the limitation of the forging machine or the material, etc., the blade root lying forging aggregation shape cannot be formed by one-time forging, so multiple times of forging are needed.

[0062] Specifically, 1.10≤M≤1.25.

[0063] S6, one sub-mold is prepared based on each rough forging hole shape, and all the sub-molds constitute a mold group of the lying forging aggregation piece rough.

[0064] The die design method of the high-temperature alloy blade lying forging aggregate blank of the embodiment can design each sub-die at each step of blanking to lying forging aggregate blank, and the shape of the blank hole of each sub-die is the same as the shape and size finally generated at the step of forging, so that no waste is generated by using the above-mentioned sub-die at each step of forging, and the forging step is simplified.

[0065] The punch hole of the sub-die prepared based on the shape of the blade tip lying forging aggregate blank hole 210 is coaxially provided with the first punch containing hole 200 and the blade tip lying forging aggregate blank hole 210 in sequence, and the blade tip end of the blade tip lying forging aggregate blank hole 210 is in communication with the first punch containing hole 200; the punch hole of the sub-die prepared based on the shape of the intermediate lying forging aggregate blank hole 310 is coaxially provided with the first rear top position containing hole 300 and the intermediate lying forging aggregate blank hole 310 in sequence, and the blade tip end of the intermediate lying forging aggregate blank hole 310 is in communication with the first rear top position containing hole 300; the punch hole of the sub-die prepared based on the shape of the target lying forging aggregate model blank hole 410 is coaxially provided with the second rear top position containing hole 400, the target lying forging aggregate model blank hole 410 and the second punch containing hole 420 in sequence, the blade tip end of the intermediate lying forging aggregate blank hole 310 is in communication with the second rear top position containing hole 400, and the blade root end of the intermediate lying forging aggregate blank hole 310 is in communication with the second punch containing hole 420.

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

[0067] In addition, the die set prepared by the method of the embodiment is handed over to a contract manufacturing enterprise for preparation, and then the subsequent preparation is prepared by the enterprise, which can shorten the preparation period of the enterprise. In the process of shortening the preparation period, the final blade structure can be protected from being disclosed, and the protection of technical secrets is realized.

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

[0070] In a specific embodiment, the die set for the lying forging aggregate blank of the A blade as shown in FIG. 1 is designed with the raw material brand of Inconel 718, the standard of AMS 5662, and the finish of Ra 0.40 (μm).

[0071] The mold set design method of the high-temperature alloy blade's upsetting aggregate blank in the embodiment is carried out in SolidWorks, and includes the following steps:

[0072] (1) a three-dimensional model of the A blade is established as shown in the figure, Figure 1 and a A blade forging model is constructed according to the three-dimensional model of the A blade as shown in the figure. Figure 2

Figure 5

[0074] (3) the volume of the A blade upsetting aggregate model is calculated, a blanking piece model is constructed with the axial diameter of the blade body upsetting aggregate part 110 of the A blade upsetting aggregate model as the diameter and the ratio of the volume of the A blade upsetting aggregate model to the axial diameter of the blade body upsetting aggregate part 110 as the length as shown in the figure.
