Description

[0001] The invention relates to the technical field of metal blade processing and forming, and in particular to a hot processing device and a processing method for a titanium alloy blade. Background Art

[0002] Metal blades, especially titanium alloy blades, have high specific strength, high temperature resistance and excellent corrosion resistance, and are widely used in high-tech fields such as aerospace, energy and power, such as turbine engines and gas turbines. However, in actual production and processing, the high strength and toughness of titanium alloys also bring challenges to processing and forming, especially in the hot working process, the demoulding problem of titanium alloy blades is a key issue that technicians in the field need to pay attention to.

[0003] Traditional heat processing equipment usually includes a fixed mold (female mold) and a movable mold (male mold). The movable mold is driven by a hydraulic or pneumatic system to complete the processing and forming of the workpiece, and cooperates with the demolding structure to efficiently remove the processed workpiece from the fixed mold. However, for titanium alloy blades, on the one hand, there is an adhesion effect after heating, and on the other hand, the titanium alloy blades are thin sheets as a whole. If the demolding structure is used for demolding, it is easy to cause scratches or micro cracks on the surface of the titanium alloy blades due to local stress concentration, resulting in low quality stability of the titanium alloy blades; if the titanium alloy blades are taken out after cooling, the production efficiency of the titanium alloy blades will be reduced.

[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0049] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0050] Embodiment 1:

[0051] The hot processing device for titanium alloy blades provided in this embodiment is suitable for hot processing scenarios of thin-walled workpieces, especially titanium alloy blades. In this embodiment, the structure of the hot processing device for titanium alloy blades is improved to solve the quality problems in the prior art such as difficulty in demolding during hot processing of titanium alloy blades and easy generation of stress concentration, surface scratches or micro cracks, thereby ensuring both the production quality stability and the production efficiency of titanium alloy blades.

[0052] like Figures 1 to 5 As shown, the hot processing device for titanium alloy blades in this embodiment includes a female mold part 100 and a male mold part 200; the female mold part 100 includes two female modules 110 that can move toward or away from each other, and when the two female modules 110 are against each other, they are spliced ​​to form a female mold cavity 101; the male mold part 200 includes a male module 210 that matches the contour of the female mold cavity 101; it should be noted that after the male module 210 is pressed down, a cavity will be formed in the female mold cavity 101, and the cavity is used to hot form the titanium alloy blade.

[0053] Among them, the mother module 110 is rotatably connected to the end of the other mother module 110 with a overlap block 300, and the overlap block 300 can rotate between a first position and a second position; when the two mother modules 110 are arranged at an interval, the overlap block 300 is located at the first position, the first position is located between the two mother modules 110, and the overlap block 300 is used to support the titanium alloy blade; when the two mother modules 110 are spliced ​​to form the mother mold cavity 101, the overlap block 300 is located at the second position, and the second position is located below the mother mold cavity 101. Among them, the edges of the mother module 110, especially the positions where two mother modules 110 are connected and spliced, need to ensure their shape accuracy so that the spliced ​​mother mold cavity 101 appears concave to ensure the heat processing quality of the titanium alloy blade; on this basis, the design of the overlap block 300 enables the titanium alloy blade to be stably supported during the demolding process, avoiding direct contact between the positions where the mother modules 110 are connected and spliced ​​and the titanium alloy blade, preventing stress concentration caused by the separation of the mother modules 110, and avoiding surface scratches or micro cracks caused by direct contact between the titanium alloy blade and the corners of the mother module 110.

[0054] Specifically, the titanium alloy blade in this embodiment uses a hot working device such as Figure 5 As shown, during the heat treatment of the titanium alloy blade, the male mold part 200 is pressed downward into the female mold cavity 101 to perform heat treatment on the heated titanium alloy blade; Figure 3 and Figure 4 As shown, after hot processing, the male mold part 200 is reset, and the two female modules 110 move back to back to form two female modules 110 arranged at intervals. At the same time, the overlap block 300 is flipped to the first position to carry the titanium alloy blade. This arrangement reduces the stress concentration caused by the direct contact between the edge and the titanium alloy blade when the mold is separated, prevents scratches or micro cracks, and improves the surface quality and overall mechanical properties of the titanium alloy blade; further, direct demolding of the titanium alloy blade at high temperature is achieved, which not only ensures quality stability but also improves production efficiency. Therefore, the hot processing device for titanium alloy blades has the advantages of high production stability and high production efficiency.

[0055] Furthermore, if Figure 1 , Figure 6 and Figure 7 As shown, a first trigger assembly 220 is provided on one side of the male module 210, which is synchronously lifted and lowered with the male module 210; the female mold part 100 also includes a female mold bottom plate 120, and the female module 110 is slidably connected to the female mold bottom plate 120; a moving assembly 400 is also installed on the female module 110, and the moving assembly 400 is used to be triggered by the first trigger assembly 220 to drive the two female modules 110 to move toward each other. A second trigger assembly 130 and a rotating assembly 140 are also installed on the female module 110, and the rotating assembly 140 is used to be triggered by the second trigger assembly 130 to drive the lap block 300 to rotate to the second position.

[0056] It is understandable that the male module 210 can be pressed down in the direction close to the female mold base plate 120 by a hydraulic device or a pneumatic device (not shown). The first trigger component 220 is arranged on one side of the male module 210 and is arranged to be raised and lowered synchronously with the male module 210, so that when the male module 210 is pressed down, the first trigger component 220 is synchronously driven to descend, and during the descent of the first trigger component 220, the two female modules 110 will be driven to move toward each other through the moving component 400, so that the two female modules 110 are spliced ​​to form a female mold cavity 101, so that the male module 210 and the female mold cavity 101 cooperate to complete the heat treatment of the titanium alloy blade; at the same time, when the two female modules 110 are spliced ​​with each other, the second trigger component 130 can drive the overlap block 300 to rotate to the second position to avoid the two overlap blocks 300 affecting the splicing between the female modules 110, thereby improving the splicing accuracy between the two female modules 110.

[0057] It should be noted that the first trigger component 220 can be a horizontal cylinder or a motor with a ball screw module arranged outside the mother module 110, which can drive the mother module 110 to slide on the mother mold base plate 120; similarly, the second trigger component 130 can be a rotating motor or a rotating cylinder arranged inside the mother module 110, which can drive the overlap block 300 to rotate between the first position and the second position.

[0058] As other optional implementations, Figure 6 and Figure 7 As shown, the first trigger component 220 includes a plurality of trigger columns 221 arranged around the outside of the male module 210, and the trigger columns 221 are extended along the downward pressing direction; the female module 110 is provided with an inner cavity 111, and the inner cavity 111 is provided with a strip groove 112 at a position corresponding to the trigger column 221. The moving component 400 includes a guide block 410 arranged in the inner cavity 111 and corresponding to the trigger column 221 one by one. The end of the guide block 410 facing the trigger column 221 is formed with a guide slope 411, and the guide slope 411 is arranged to descend in the direction away from the other female module 110.

[0059] Specifically, the first trigger assembly 220 effectively controls the relative movement of the female module 110 through the trigger column 221 that rises and falls synchronously with the male module 210. When the male module 210 is pressed down, the trigger column 221 guides the movement of the female module 110 to ensure that the female module 110 is accurately spliced ​​to form the female mold cavity 101, effectively avoiding the processing error caused by the loose mold docking; making the female module 110 have high stability during the movement. That is, through the cooperation of the guide block 410 and the trigger column 221, the guide block 410 slides along the guide slope 411, reducing the friction and uneven movement that may be generated when the female module 110 slides, thereby ensuring the smooth movement of the female module 110 and reducing the stress concentration caused by the uneven movement of the female module 110.

[0060] Furthermore, if Figures 7 to 10 As shown, the rotating assembly 140 includes a rotating shaft member rotatably connected to the inner cavity 111, and the lap block 300 includes a rotating end 310 and a bearing end 320, and the rotating end 310 is sleeved outside the rotating shaft member and fixedly connected to the rotating shaft member; the second trigger assembly 130 includes a sliding block 131 that is slidably connected to the inner cavity 111 and located below the strip groove 112, and the sliding block 131 has a trigger hole 132 at a position corresponding to the trigger column 221; a fixed line block 133 is provided on the sliding block 131; a wire unit is passed through the fixed line block 133, and the end of the wire unit is surrounded and fixed outside the rotating shaft member. The structure of the wire unit can be made of steel wire or high-strength synthetic fiber, and its tension and flexibility are used to ensure that the lap block 300 can stably and smoothly rotate from the first position to the second position.

[0061] It can be understood that, after the trigger column 221 passes through the strip groove 112 and before it contacts the guide slope 411, the trigger column 221 passes through the trigger hole 132, which means that the sliding block 131 is sleeved outside the trigger column 221 through the trigger hole 132, that is, the sliding block 131 is locked at this time; then, the trigger column 221 continues to press down, pushing the guide block 410 to move through the guide slope 411, so that the two mother modules 110 move toward each other, and at this time the strip groove 112 slides relative to the trigger column 221, and The sliding block 131 is sleeved outside the trigger column 221 through the trigger hole 132, which means that the strip groove 112 also moves relative to the sliding block 131, and the lap block 300 is connected to the mother module 110 through the rotating shaft in the inner cavity 111, which means that when the two mother modules 110 move toward each other, the lap block 300 moves inward, while the position of the sliding block 131 remains unchanged. At this time, the fixed line block 133 pulls the lap block 300 through the line unit, so that the lap block 300 rotates to the second position. The above scheme, especially the setting of the line unit, is less affected by temperature, especially in a high temperature environment, the performance of its steel wire or high-strength synthetic fiber remains stable, reducing the wear of mechanical parts and the occurrence of system failures, thereby improving the long-term stability of the hot processing device for titanium alloy blades. In addition, the traction design of the wire unit makes the rotation of the overlap block 300 softer and smoother, without causing sudden mechanical shock or uneven stress distribution, and can effectively prevent the occurrence of defects such as scratches and micro cracks on the surface of the titanium alloy blade, thereby improving the surface quality and mechanical properties of the titanium alloy blade.

[0062] More specifically, Figure 9 and Figure 10As shown, two guide blocks 410 are arranged in the inner cavity 111, and the sliding block 131 includes a sliding plate 1311 attached to the cavity wall of the inner cavity 111; a vertical plate 1312 is convexly arranged on the sliding plate 1311, and the vertical plate 1312 extends between the two guide blocks 410; a second guide rail 152 is also installed between the two guide blocks 410, and the vertical plate 1312 is slidably connected to the second guide rail 152 through a slider. Among them, the vertical plate 1312 extends between the two guide blocks 410 and is slidably connected to the second guide rail 152 through a slider, which can effectively prevent the sliding block 131 from lateral displacement, and fully utilize the space between the two guide blocks 410, so that the overall structure is more compact, and at the same time, the error caused by the instability or misalignment of the sliding block 131 is avoided, and the stability and accuracy of the mother module 110 when splicing is improved. In addition, the sliding block 131 is attached to the cavity wall of the inner cavity 111, and through the sliding connection with the second guide rail 152, the friction between the sliding block 131 and other components can be effectively reduced, reducing the wear problem caused by friction during long-term use, thereby improving the durability and stability of the equipment; and the sliding cooperation between the sliding plate 1311 and the second guide rail 152 also makes the operation smoother, reducing the risk of failure caused by poor sliding or jamming. On this basis, the smooth movement of the sliding plate 1311 can ensure that the lap block 300 maintains a stable and precise trajectory during the rotation process, avoids the deviation of the lap block 300 during rotation, ensures the smooth transition of the rotation action of the lap block 300 between the first position and the second position, and reduces the difficulty of demolding or damage to the blade surface caused by inaccurate position.

[0063] On the basis of the above-mentioned embodiment, a positioning hole 412 is further provided on the guide block 410, and the positioning hole 412 is arranged on the side of the guide slope 411 away from the lap block 300; when the two female modules 110 are spliced ​​to form the female mold cavity 101, the triggering posts 221 are inserted into the positioning holes 412 one by one. It should be understood that when the triggering posts 221 are inserted into the positioning holes 412, the relative positions of the female modules 110 are locked, avoiding the misalignment problem caused by inertia or slight displacement of the female modules 110 during the process of moving toward each other, ensuring the splicing accuracy of the female mold cavity 101, enabling the male module 210 to accurately cooperate with the female mold cavity 101, avoiding the processing error caused by the loose docking of the female modules 110, thereby improving the molding quality of the titanium alloy blade. Next, the positioning hole 412 provides additional support and restraint, so that the female module 110 will not slip laterally during the splicing process, reducing the device offset caused by mechanical vibration or the impact force generated during the pressing process of the male module 210, thereby ensuring the long-term reliable operation of the entire processing device. Furthermore, since the trigger column 221 and the positioning hole 412 can achieve self-locking, the alignment process of the female module 110 becomes automated, without the need for additional manual intervention or auxiliary alignment mechanism, thereby reducing processing time, improving production efficiency, and meeting the needs of mass production.

[0064] On the basis of the above embodiment, the mother mold base plate 120 is provided with a sliding groove 121, in which at least two first guide rails 151 arranged at intervals are installed, and the mother mold block 110 is slidably connected to the corresponding first guide rails 151 through a slider. The setting of the first guide rails 151 makes the sliding of the mother mold block 110 smoother, so as to improve the processing accuracy of the titanium alloy blade.

[0065] At the same time, a torsion spring (not shown) is installed between the rotating shaft and the inner cavity 111, and a tension spring (not shown) is installed in the sliding groove 121, so that after the male module 210 is reset, the spring can push the two female modules 110 to move in opposite directions, and the tension spring can drive the rotating shaft to reset, so that the overlapping block 300 is reset to the first position, and the spring can push the two female modules 110 apart; illustratively, the tension spring is installed on the groove side wall of the sliding groove 121, one end of which is fixedly connected to the groove side wall of the sliding groove 121, and the other end is fixedly connected to the bottom wall of the female module 110. When the two female modules 110 are acted upon by the trigger column 221 to move toward each other, When moving, the tension spring is stretched; correspondingly, when the trigger column 221 is reset, the tension spring pulls the mother module 110 to reset, so that the two mother modules 110 move in opposite directions; similarly, when the trigger column 221 is pressed down, the rotating shaft overcomes the torsion force of the torsion spring and drives the lap block 300 to rotate from the first position to the second position. When the trigger column 221 is reset, the torsion spring drives the rotating shaft to rotate to drive the lap block 300 to reset to the first position; at the same time, the setting of the torsion spring makes the lap block 300 have a certain elasticity, avoiding the rigid contact between the lap block 300 and the titanium alloy blade, thereby improving the production quality of the titanium alloy blade.

[0066] Based on the above implementation, Figure 7 and Figure 8 As shown, the inner cavity 111 of the mother module 110 is provided with an avoidance opening 113 toward the cavity wall of the other mother module 110, and the avoidance opening 113 is located between the first position and the second position, and is used to avoid the overlap block 300; the opening edge of the avoidance opening 113 is formed with a first abutment slope 114, and the load-bearing end 320 is provided with a second abutment slope 321 at a position corresponding to the first abutment slope 114; when the two mother modules 110 are arranged at intervals, the second abutment slope 321 abuts against the first abutment slope 114.

[0067] The design of the first abutting bevel 114 and the second abutting bevel 321 enables the mother module 110 to be accurately butted when spliced. When the two mother modules 110 are spaced apart, the second abutting bevel 321 abuts against the first abutting bevel 114, thereby ensuring that the butting position of the mother module 110 does not shift. This design improves the stability of the device, ensures the accuracy of the mother mold cavity 101 during the formation process, and avoids the situation where the heat treatment effect is affected due to mold misalignment.

[0068] Embodiment 2:

[0069] This embodiment provides a titanium alloy blade processing method, which uses the titanium alloy blade heat processing device in the first embodiment, including:

[0070] Step S1, placing an initial blade on two spaced-apart mother modules 110, and heating the initial blade, one end of the initial blade being supported on one mother module 110 and a corresponding overlap block 300, and the other end of the initial blade being supported on another mother module 110 and a corresponding overlap block 300;
