Description

Technical Field

[0001] The invention relates to the technical field of turbine blade processing, and in particular to a turbine blade wax mold forming device and method. Background Art

[0002] Turbine blades are core components of aircraft engines and gas turbines, and their manufacturing process requires extremely high precision and complex shapes. Traditional turbine blade manufacturing processes mostly use lost wax casting, in which the precision of the wax mold, structural strength and control of the molding process are key factors affecting the quality and cost of the casting.

[0003] The existing equipment has the following disadvantages: the existing wax mold structure often has problems such as ceramic core breakage, incomplete wax mold pouring, and insufficient wax mold strength in the casting of small and complex structures, resulting in molding failure or casting defects. In addition, the traditional positioning device generally supports the ceramic core through a fixed push rod. When the core position is offset, the top of the fixed push rod needs to be ground down until the height of the fixed push rod meets the requirements. However, when the fixed push rod is worn down a lot, a new fixed push rod needs to be replaced and then adjusted, resulting in low core positioning efficiency, thereby affecting the molding efficiency of the turbine blade wax mold.

[0019] Wherein, a storage groove for placing the wax core is opened on the lower mold core.

[0020] A turbine blade wax mold forming method, used for operating the above-mentioned turbine blade wax mold forming device, comprises the following steps:

[0022] S2. Detect the cross section of the core by ultrasonic wall thickness detection, detect the wall thickness, place the core on the positioning device, and measure the distance between the core and the inner wall of the lower mold core with a go / no-go gauge. If the distance is not in accordance with the size, adjust the distance between the core and the inner wall of the lower mold core by the adjustment device corresponding to the positioning device to ensure that the wall thickness is uniform. After the adjustment is qualified, fix the installation position of the positioning device by the adjustment device;

The high efficiency ensures the high quality of the turbine blade casting process. During the rotation of the rotating shaft, the gear meshes with the rack. The rack is fixed to the lower end of the moving rod and moves with the movement of the rack. When the rack rotates, the moving rod moves in the moving groove, so that the moving rod pushes the first positioning rod to extend or retract from the lower die core, completing the adjustment of the positioning rod in the lower die core. Accurate positioning not only improves product quality, but also reduces the time wasted due to mold adjustment. This design enables the molding mold to maintain consistent performance in continuous production, reduces downtime and maintenance costs, and thus improves overall production efficiency.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-12 The present invention provides a technical solution: a turbine blade wax mold forming device, comprising a lower mold 1 for placing a core 31, an upper mold 2 adjustably arranged at the upper end of the lower mold 1, and an ejection mechanism 4 arranged on the lower mold 1 for ejecting the pressed molding mold 3, and also comprising:

[0042] A positioning device 5 is provided in the lower mold core 11 at the upper end of the lower mold 1 and is used to support and position the core 31;

[0043] An adjusting device 6, which is arranged on the lower mold 1 and connected to the positioning device 5, and is used to adjust the installation position of the positioning device 5;

[0044] The regulating device 6 comprises:

[0045] An adjusting member, which is arranged at a position corresponding to the positioning device 5 on the lower mold core 11 and is connected to the positioning device 5, and is used to adjust the installation position of the corresponding positioning device 5;

[0046] The fixing member 64 is disposed on the adjusting member and abuts against the lower die core 11 , and is used to fix the installation position of the adjusting member.

[0047] It should be noted that, during operation, the core 31 is placed on the positioning device 5 in the lower mold core 11. The positioning device 5 adopts six-point positioning to control the position of the ceramic core 31 in the lower mold core 11, and uses a go / no-go gauge to detect the thickness gap of the core 31 in the lower mold core 11. When it is detected that the thickness size does not meet the standard, the adjusting member is rotated to drive the positioning device 5 to move up and down inside the lower mold core 11, so that the distance between the core 31 and the lower mold core 11 meets the design requirements, and then the position of the positioning device 5 is fixed by the fixing member 64, which can realize the rapid and precise adjustment of the installation position of the positioning device 5, thereby conveniently adjusting the distance between the core 31 and the inner wall of the lower mold core 11 to ensure the wall thickness size. The size is uniform, the response speed and adjustment efficiency of the production process are improved, and it is ensured that the wall thickness of the molding die 3 meets the requirements after the pressing is completed. For the excessive shrinkage of the molding die 3 during the pressing process, it is necessary to adopt the method of pre-embedded cold wax core 7. According to the size of the ceramic core 31 and the molding die 3, the thickness cross-sectional shrinkage area of ​​the wax in the cavity is analyzed, and cold wax core 7 is set in these areas to reduce the shrinkage of the wax mold in the subsequent wax pressing process. After the film pressing is completed, the molding die 3 is ejected from the lower mold core 11 by the ejection mechanism 4, which can reduce the shrinkage of the blade and finally achieve the precision requirement of controlling the dimensional tolerance of the casting, improve the strength, precision and molding efficiency of the traditional wax mold, and ensure the high quality of the turbine blade casting process.

[0048] In one embodiment, the positioning device 5 includes a third positioning rod 53 and a fifth positioning rod 55 which are passed through the bottom of the lower mold core 11 to support the bottom of the core 31, a second positioning rod 52 and a fourth positioning rod 54 which are passed through the lower part of the lower mold core 11 to support one side of the core 31, a first positioning rod 51 which is passed through one side of the lower mold core 11 to support the other side of the core 31, and a sixth positioning rod 56 which is passed through the lower mold core 11 on the injection port side to support the head of the core 31.

[0049] This design, see Figure 2 ,as well as Figure 7-12, the bottom of the core 31 is supported by the third positioning rod 53 and the fifth positioning rod 55, ensuring the stability of the core 31 in the vertical direction. At the same time, the second positioning rod 52 and the fourth positioning rod 54 support the core 31 from one side, while the first positioning rod 51 supports it from the other side. The sixth positioning rod 56 is set on the side of the injection port for additional support of the head of the core 31. This multi-point positioning method significantly improves the position accuracy of the core 31 in the mold and reduces production problems caused by position deviation. Accurate positioning not only improves product quality, but also reduces the time wasted due to mold adjustment. This design enables the molding mold 3 to maintain consistent performance in continuous production, reduces downtime and maintenance costs, and thus improves overall production efficiency.

[0050] In one embodiment, the ejection mechanism 4 includes a rotating rod 41 passing through the lower mold core 11, a top plate 42 fixed on the rotating rod 41 and eccentrically arranged, a lifting plate 44 passing through the lower mold 1 and a ejector rod 45 fixed at the upper end of the lifting plate 44 and passing through the lower mold core 11, the lifting plate 44 is located above the top plate 42, an adjusting handle 43 is provided on one side of the rotating rod 41 located outside the lower mold 1, and a through hole 1101 for the ejector rod 45 to move is opened at the position corresponding to the ejector rod 45 on the lower mold core 11.

[0051] This design, see Figure 5 ,as well as Figure 6 The setting of the adjustment handle 43 allows the operator to easily adjust the position of the rotating rod 41, thereby controlling the rotation of the rotating rod 41. The top plate 42 rotates along the rotating rod 41, and then the lifting plate 44 moves up, so that the ejector rod 45 ejects the forming mold 3 in the lower mold core 11. The perforation 1101 can accurately guide the ejector rod 45 to ensure the accuracy and consistency of the ejection action. This design reduces the position deviation during the ejection process and improves the product quality.

[0052] In one embodiment, the adjusting member includes a moving rod 62 passed through the lower mold 1, a transmission member 63 arranged on the lower mold core 11 and connected to the moving rod 62, and a rotating shaft 633 passed through the lower mold core 11. A moving groove 102 for the moving rod 62 to move is opened on the lower mold 1, and the moving rod 62 is in contact with the inner wall of the moving groove 102.

[0053] This design, see Figure 8-12Through the precise movement of the moving rod 62 in the moving groove 102, and the coordinated action of the transmission member 63 and the rotating shaft 633, the adjusting member can control the position of the first positioning rod 51, and each positioning rod is provided with an adjusting device 6 on its side for adjusting the distance of the first positioning rod 51, the second positioning rod 52, the third positioning rod 53, the fourth positioning rod 54 and the fifth positioning rod 55 extending out of the lower mold core 11, ensuring the accuracy of the positioning rod for positioning the core 31, so that the molding mold 3 can adapt to production requirements of different sizes and precisions. The moving groove 102 provides a clear moving path for the moving rod 62, so that the operator can easily make adjustments. The moving rod 62 fits with the inner wall of the moving groove 102, ensuring the stability of the adjusting member during movement, reducing shaking and deviation during adjustment, and improving the overall stability of the mold.

[0054] In one embodiment, the transmission member 63 includes a rack 631 fixed to the lower end of the moving rod 62 and a gear 632 sleeved on the rotating shaft 633 and meshingly connected to the rack 631. The lower mold 1 is provided with a mounting groove 103 for the rack 631 to move and connected to the moving groove 102.

[0055] This design, see Figure 8-12 The gear 632 is fixed on the rotating shaft 633. During the rotation of the rotating shaft 633, the gear 632 is meshed with the rack 631. The rack 631 is fixed to the lower end of the moving rod 62 and moves with the movement of the rack 631. When the rack 631 rotates, the moving rod 62 moves in the moving groove 102, so that the moving rod 62 pushes the first positioning rod 51 to extend or retract from the lower mold core 11. The meshing connection between the rack 631 and the gear 632 has high reliability. Due to the design of the tooth shape, the contact area between them is large, so they can withstand large loads and are not prone to slippage or tooth disengagement.

[0056] In one embodiment, the fixing member 64 includes a rotating plate 641 fixed on the rotating shaft 633, a screw 642 threadedly connected to the rotating plate 641, an abutment plate 643 fixed on the side of the screw 642 close to the gear 632, and a handle 644 fixed on the other side of the screw 642. A rotating groove 101 for the rotating plate 641 to rotate is opened on the lower mold 1, and the abutment plate 643 abuts against the inner wall of the rotating groove 101.

[0057] This design, see Fig.12By rotating the handle 644, the screw 642 can be driven to move on the rotating plate 641. When the abutment plate 643 is tightly abutted against the inner wall of the rotating groove 101, the rotating shaft 633 is firmly locked to prevent it from accidentally rotating during operation, thereby ensuring the stability and safety of the fixation of the first positioning rod 51. When the position of the first positioning rod 51 needs to be adjusted, the handle 644 is rotated to separate the abutment plate 643 from the inner wall of the rotating groove 101, thereby releasing the fixation of the position of the first positioning rod 51. Then, the handle 644 is rotated to make the rotating shaft 633 drive the gear 632 to rotate, thereby making the rack 631 push the moving rod 62 to move inside the moving groove 102.

[0058] In one embodiment, a placement frame 61 for placing a fixed block 511 on the first positioning rod 51 is provided on the movable rod 62 near the first positioning rod 51, and the fixed block 511 abuts against the inner wall of the placement groove 6101 on the placement frame 61, and an adjustment groove 104 is opened on the lower mold 1 for the first positioning rod 51 to move.

[0059] This design, see Fig. 9 The design of the placement frame 61 provides a precise placement position for the fixed block 511 on the first positioning rod 51. When the fixed block 511 is placed in the placement groove 6101 and abuts against the inner wall, the accurate positioning of the first positioning rod 51 is ensured, thereby improving the positioning accuracy and processing accuracy of the mold. The close abutment between the fixed block 511 and the inner wall of the placement groove 6101 increases the stability of the first positioning rod 51 during movement. This design reduces the shaking and deviation of the positioning rod during processing, which helps to maintain the stability and processing quality of the mold. The operator only needs to place the fixed block 511 into the placement groove 6101, and then adjust the position of the positioning rod by moving the moving rod 62 in the moving groove 102, which simplifies the operating steps and improves work efficiency.

[0060] In one embodiment, a limiting plate 611 for limiting the first positioning rod 51 is fixed to one side of the upper end of the placement frame 61 , and a through slot 6102 for placing the first positioning rod 51 is formed on the limiting plate 611 .

[0061] This design, see Fig.11 A limiting plate 611 for limiting the first positioning rod 51 is fixed to one side of the upper end of the placement frame 61. A through slot 6102 for placing the first positioning rod 51 is provided on the limiting plate 611 to prevent the first positioning rod 51 from shifting or shaking during operation. The through slot 6102 also ensures the stability of the positioning rod during movement.

[0062] In one embodiment, a storage groove 105 for placing the wax core 7 is formed on the lower mold core 11 .

[0063] This design, see Figure 4 The storage slot 105 provides accurate positioning for the wax core 7, ensuring the accurate position of the wax core 7 in the mold, thereby improving the accuracy and quality of subsequent processes.

[0064] A turbine blade wax mold forming method, used for operating the above-mentioned turbine blade wax mold forming device, comprises the following steps:

[0065] S1. According to the shape of the turbine blade wax model, the cavity shapes of the upper mold core 21 and the lower mold core 11 are designed to complete the design and manufacture of the wax mold;

[0066] S2, detect the cross section of the core 31 by ultrasonic wall thickness detection, detect the wall thickness, place the core 31 on the positioning device 5, and use a go / no-go gauge to measure the distance between the core 31 and the inner wall of the lower mold core 11. If the distance is not in the right size, adjust the distance between the core 31 and the inner wall of the lower mold core 11 by the adjusting device 6 corresponding to the positioning device 5 to ensure that the wall thickness is uniform. After the adjustment is qualified, fix the installation position of the positioning device 5 by the adjusting device 6;

[0067] S3, according to the ceramic core 31 and the molding mold 3, analyze the thickness and cross-sectional shrinkage areas of the wax in the cavity, set wax cores 7 in these areas to reduce the shrinkage of the wax mold in the subsequent wax pressing process, close the mold to check whether there is any damage to the ceramic core, close the mold after completion, and press the wax mold;

[0068] S4. After the casting process is completed, the blade shape and wall thickness are tested. According to the previous test results, it is tested whether the molded casting meets the accuracy requirements of the casting size tolerance. If it does not meet the accuracy requirements, steps S2 to S3 are repeated until the final design mold 3 and the position of the ceramic core 31 meet the wall thickness and shape size tolerance requirements.
