Technical Field

[0001] The invention relates to the technical field of bending mechanisms, in particular to a titanium alloy plate bending mechanism. Background Art

[0003] Traditional titanium alloy plate bending equipment usually includes basic components such as the bending machine body and bending knife. A moving seat is set in the bending machine body to carry the bending knife. The bending knife bends the titanium alloy plate under the drive of the moving seat.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the specification 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.

[0036] See also Figure 1-Figure 13The embodiment of the present invention provides a titanium alloy plate bending mechanism, including a base 1, and a bending machine body 2 is arranged on one side of the top of the base 1, and the bending machine body 2 is the prior art. A moving seat 201 is arranged inside the bending machine body 2, and the moving seat 201 serves as a bearing component of a bending knife 202, and can move along a specific track in the bending machine body 2. A bending knife 202 is arranged at the bottom of the moving seat 201, and the bending knife 202 is a key component that directly acts on the titanium alloy plate to achieve bending. It is installed at the bottom of the moving seat 201, and can move accurately with the moving seat 201, accurately apply pressure to the titanium alloy plate placed below, and complete the bending action. An adjustment mechanism 3 is arranged on one side of the top of the base 1, and the correction mechanism 4 is adjusted to a suitable height to ensure that the titanium alloy plate can be in the best position when passing through the correction mechanism 4. A correction mechanism 4 is arranged on the top of the adjustment mechanism 3, and after the height of the adjustment mechanism 3 is adjusted, the correction mechanism 4 can correct the position of the titanium alloy plate passing thereon. An adjustment mechanism 5 is provided on the outside of the bending machine body 2 to adjust the bending curvature. Automatic adjustment is achieved by changing the support position and height, which effectively reduces the large amount of debugging time consumed by adjusting the bending curvature under the traditional production method and optimizes the production process. The top of the adjustment mechanism 5 is located below the bending knife 202. A heating mechanism 6 is provided on the outer side of the base 1. Heating the titanium alloy plate can reduce its strength and make the bending operation easier.

[0037] The adjusting mechanism 5 includes an adjusting seat 501, the bottom of which is fixedly connected to the outside of the bending machine body 2, providing a stable installation foundation for the entire adjusting mechanism 5. The adjusting mechanism 5 is connected to the bending machine body 2 to ensure that the relative position between the two is fixed. The adjusting seat 501 is fixedly connected to a support seat 502 on the side away from the adjustment mechanism 3, and the support seat 502 provides a stable support platform for the micro motor 503. A micro motor 503 is installed on the top of the support seat 502. The micro motor 503 is a prior art. As a power source, the micro motor 503 can accurately control the power output. Provide a stable and adjustable rotational power for the bidirectional threaded rod 504, so that the entire adjustment process can be automatically controlled. The output end of the micro motor 503 is fixedly connected to a bidirectional threaded rod 504, which is connected to the micro motor 503, converts the rotational motion of the motor into linear motion, and enables the two moving plates 505 to move toward or away from each other. The outer side of the bidirectional threaded rod 504 is threadedly connected with two moving plates 505, which move under the drive of the bidirectional threaded rod 504, converting the rotational motion of the threaded rod into its own linear motion, thereby driving the adjustment plate 506 to move. The top of the moving plate 505 is rotatably connected with the adjustment plate 506, and the rotational connection between the adjustment plate 506 and the moving plate 505 enables the adjustment plate 506 to change its angle accordingly when the moving plate 505 moves. The top of the adjustment plate 506 is fixedly connected with a connecting rod 507, which serves to connect the adjustment plate 506 and the adjustment seat 501. By cooperating with the adjustment seat 501 (the end slides in the adjustment groove 508), the connecting rod 507 further limits the range and mode of movement of the adjustment plate 506. Two adjustment grooves 508 are provided on both sides of the outside of the adjustment seat 501. The ends of the connecting rods 507 are slidably connected to the inner walls of the adjustment grooves 508. The adjustment grooves 508 provide precise guidance and restriction for the movement of the connecting rods 507, and define the movement path of the connecting rods 507, so that the ends of the adjustment plate 506 can only slide in the adjustment grooves 508 during the rotation process, thereby avoiding the random swing or offset that may occur during the adjustment process, and ensuring the accuracy and stability of the adjustment. The bottoms of the two connecting rods 507 are provided with guide components, which are used to guide the moving plate 505 when it moves.

[0038] See also Figure 4-Figure 7The guide assembly includes a limit plate 5010, and the outer sides of the two limit plates 5010 are fixedly connected to the outer sides of the connecting rod 507 respectively. The limit plates 5010 provide a support structure for the electric telescopic rod 5011. The electric telescopic rod 5011 is installed at the bottom of the limit plate 5010, which can automatically adjust the length according to the movement of the moving plate 505, and provide appropriate power and displacement compensation for the sliding of the slide plate 5012 in the slide groove 5013. During the adjustment process, different adjustment requirements will cause the moving plate 505 and the connecting rod 507 to have different movement trajectories. The electric telescopic rod 5011 can adapt to these changes in real time to ensure the accuracy of the guidance. The telescopic end of the electric telescopic rod 5011 is fixedly connected to a slide plate 5012, and the inner bottom wall of the adjustment seat 501 is provided with two slide grooves 5013. The outer side of the slide plate 5012 is slidably connected to the inner wall of the slide groove 5013. The cooperation between the slide plate 5012 and the slide groove 5013 provides a stable guiding path for the connecting rod 507, ensuring that the connecting rod 507 will not deviate from the predetermined trajectory during movement.

[0039] See also Figure 4-Figure 5 The inner side of the adjustment seat 501 is fixedly connected to a limit rod 509, and the outer side of the limit rod 509 is slidably connected to the internal through hole of the movable plate 505, providing precise guidance for the movement of the movable plate 505. When the movable plate 505 moves driven by the bidirectional threaded rod 504, the limit rod 509 limits the moving direction of the movable plate 505 so that it can only move linearly along the axial direction of the limit rod 509.

[0040] See also Figure 1 , Figure 8 , Fig. 9 and Fig.10The adjustment mechanism 3 includes an adjustment plate 1 301 and an adjustment plate 2 309. The bottom of the adjustment plate 1 301 is fixedly connected to the top side of the base 1. The adjustment plate 1 301 provides a stable support base for the entire adjustment mechanism 3. Through the connection with the base 1, the adjustment mechanism 3 is firmly fixed to the top of the base 1. The inner side of the adjustment plate 1 301 is fixedly connected with a fixed plate 302, and the fixed plate 302 provides a stable installation platform for the micro cylinder 303. The top of the fixed plate 302 is installed with a micro cylinder 303. The micro cylinder 303 is a prior art. The micro cylinder 303 serves as the power source of the mobile frame 304. The output end of the micro cylinder 303 is fixedly connected with the mobile frame 304. The mobile frame 304 plays a connecting role in the adjustment mechanism 3. It receives power from the micro cylinder 303, and through the connection with the slider 1 305, the connecting rod 1 306 and other components, the power is further transmitted and converted to achieve the position adjustment of the adjustment plate 2 309, which provides a basis for the subsequent height adjustment of the correction mechanism 4. Both ends of the outer side of the moving frame 304 are rotatably connected with a slider 1 305, and the outer side of the slider 1 305 is slidably connected to the inner wall of the adjustment plate 1 301. When the moving frame 304 moves under the drive of the micro cylinder 303, the slider 1 305 can slide on the inner wall of the adjustment plate 1 301, thereby driving the connecting rod 1 306 to rotate. The outer side of the moving frame 304 is rotatably connected with two connecting rods 1 306, and the inner wall end of the adjustment plate 1 301 is rotatably connected with two connecting rods 2 307. The connecting rod 1 306 and the connecting rod 2 307 are connected by a rotating shaft. The connecting rod mechanism composed of the connecting rod 1 306 and the connecting rod 2 307 plays a key role in the transmission of force and motion conversion in the adjustment mechanism 3. They are connected by a rotating shaft to convert the linear motion of the moving frame 304 into a form suitable for the motion of the adjustment plate 2 309. One end of the connecting rod 1 306 is rotatably connected to the inner end of the adjusting plate 2 309, and one end of the connecting rod 2 307 is rotatably connected to the slider 2 308. The outer side of the slider 2 308 is slidably connected to the inner wall of the adjusting plate 2 309. The adjusting plate 2 309 is the final output part of the adjusting mechanism 3, and the adjustment of its position directly affects the height of the correction mechanism 4. Through the connection of the connecting rod 1 306 and the slider 2 308, and the sliding of the slider 2 308 on the inner wall of the adjusting plate 2 309, the power from the micro cylinder 303 is converted into the lifting motion of the adjusting plate 2 309. This motion conversion method can accurately control the height position of the adjusting plate 2 309 and adjust the correction mechanism 4 to a suitable height.

[0041] See also Figure 1 , Fig.10 ,and Fig.11The correction mechanism 4 includes a mounting plate 401, the bottom of which is fixedly connected to the top of the second adjustment plate 309, providing a stable installation base for the correction mechanism 4, ensuring that the correction mechanism 4 will not shake or shift due to external forces during operation. Through the connection with the second adjustment plate 309, the correction mechanism 4 can adapt to titanium alloy plates of different thicknesses as the height of the second adjustment plate 309 is adjusted, thereby improving the versatility and flexibility of the equipment. Connecting blocks 402 are fixedly connected to both sides of the top of the mounting plate 401, and the connecting blocks 402 provide mounting and support points for the guide rod 403, ensuring the stability and linear motion accuracy of the guide rod 403 during operation. The guide rod 403 is slidably connected to the internal through hole of the connecting block 402, and the guide rod 403 provides precise guidance for the correction plate 406, ensuring that the correction plate 406 always maintains linear motion during movement without displacement or rotation. The adjacent ends of the two guide rods 403 are fixedly connected with a correction plate 406. Through the connection with the guide rods 403, the correction force can be evenly transmitted to the titanium alloy plate to achieve the correction of the position of the titanium alloy plate. The outer side of the guide rod 403 is sleeved with a correction spring 405, one end of the correction spring 405 is fixedly connected to the outer side of the correction plate 406, and the other end of the correction spring 405 is fixedly connected to the outer side of the connection block 402. The correction spring 405 provides elastic force for the correction plate 406, so that the correction plate 406 can adapt to titanium alloy plates of different thicknesses. When the titanium alloy plate is placed between the correction plates 406, the correction spring 405 will be compressed, and the elastic force generated will make the correction plate 406 fit the titanium alloy plate tightly, ensuring the correction effect and accuracy.

[0042] See also Figure 10-11 The end of the guide rod 403 away from the correction plate 406 is fixedly connected to the limit block 404, and the limit block 404 is arranged on the edge of the connection block 402 close to the mounting plate 401. The guide rod 403 is fixedly connected to the limit block 404, so that the guide rod 403 has a clear limit end point during the movement, preventing the guide rod 403 from escaping from the connection block 402. During the correction process, when the titanium alloy plate applies a large pressure to the correction plate 406, causing the guide rod 403 to move away from the correction plate 406, the limit block 404 will be blocked by the connection block 402. In this way, the guide rod 403 is effectively prevented from detaching from the connection block 402 due to excessive movement, ensuring that the correction mechanism 4 can work continuously and stably.

[0043] See also Figure 1 , Fig.12 and Fig.13The heating mechanism 6 includes a support plate 601, a gas storage box 6011 and a valve 6012. The support plate 601 is arranged on the outer side of the base 1. The support plate 601 provides a stable installation platform for other components of the heating mechanism 6. The support plate 601 is arranged on the outer side of the base 1, which can not only utilize the overall layout space of the equipment, but also keep a certain distance from other parts of the bending mechanism to avoid unnecessary thermal effects on other components during the heating process. The gas storage box 6011 is arranged on the top side of the support plate 601, providing a stable gas storage space. The gas storage box 6011 can store a certain amount of combustible gas (such as fuel gas, etc.) to provide a continuous fuel supply for the flame burning head 609. The outer side of the gas storage box 6011 is connected to an air inlet pipe 1 606, one end of which is fixedly connected to the input end of the valve 6012, and the output end of the valve 6012 is fixedly connected to an air inlet pipe 2 607, and the air inlet pipe 1 606 and the air inlet pipe 2 607 form a gas delivery channel. They transport the combustible gas in the gas storage box 6011 to the flame burning head 609 to provide fuel for heating. The setting of valve 6012 realizes accurate control of gas flow. By adjusting the opening of valve 6012, the gas flow can be adjusted according to different heating requirements, thereby controlling the size and intensity of the flame. This is very important for the heating operation of titanium alloy plates of different thicknesses and materials, and can achieve accurate temperature control and improve the effect and quality of heating. One end of the air inlet pipe 2 607 is connected to a gas distribution pipe 608, and the top of the gas distribution pipe 608 is fixedly connected to a flame burning head 609, and the gas distribution pipe 608 evenly distributes the gas to each flame burning head 609. Through the diversion effect of the gas distribution pipe 608, multiple flame burning heads 609 can work simultaneously, improving the efficiency and uniformity of heating. At the same time, the design of the gas distribution pipe 608 can also adjust the number and layout of the flame burning heads 609 according to actual needs to meet the heating requirements of titanium alloy plates of different sizes and shapes.

[0044] See also Figure 1 and Fig.12 The top of the support plate 601 is fixedly connected with a support rod 602, and the outer side of the support rod 602 is slidably connected with a moving sleeve 603. The moving sleeve 603 is connected to the support rod 602 through a fastening bolt 605. The support rod 602 provides stable support and guidance for the moving sleeve 603. The setting of the moving sleeve 603 realizes the position adjustment function of the flame burning head 609. By sliding the moving sleeve 603 on the support rod 602, the height and horizontal position of the flame burning head 609 can be quickly and conveniently changed, so that it can be accurately aligned with the part of the titanium alloy plate that needs to be heated. The fastening bolt 605 is used to fix the position of the moving sleeve 603. When the flame burning head 609 is adjusted to a suitable position, the fastening bolt 605 cooperates with the threaded hole on the outer side of the support rod 602 to firmly fix the moving sleeve 603 on the support rod 602 to prevent the moving sleeve 603 from sliding or shifting during the heating process.

[0045] See also Figure 1 and Figure 2 The outside of the movable sleeve 603 is fixedly connected with a connecting plate 604, and the outer side of the connecting plate 604 is fixedly connected to the outer side of the gas distribution pipe 608. The connecting plate 604 connects the movable sleeve 603 and the gas distribution pipe 608. Through the fixed connection of the connecting plate 604, the position adjustment of the movable sleeve 603 can be directly transmitted to the gas distribution pipe 608 and the flame burning head 609, thereby realizing precise control of the heating position.

[0046] See also Figure 1 and Fig.13 The outer side of the flame burning head 609 is fixedly connected with a connecting plate 6010, which provides additional fixation and support for the flame burning head 609. By being fixedly connected to the flame burning head 609, the connecting plate 6010 can enhance the structural stability of the flame burning head 609 and prevent the flame burning head 609 from being deformed or damaged due to the impact force of the flame or external force during the heating process.

[0047] Working principle: The micro motor 503 is started to drive the bidirectional threaded rod 504 to rotate. The bidirectional threaded rod 504 causes the two moving plates 505 to move toward each other (the opposite is true). The movement of the moving plate 505 causes the top adjustment plate 506 to rotate. When the adjustment plate 506 moves, it drives the end of the connecting rod 507 to slide in the adjustment slot 508 of the adjustment seat 501, limiting the rotation mode of the adjustment plate 506 so that it can only rotate around a specific point. As the adjustment plate 506 rotates, the height position of its top will change. The synchronous rotation of the two adjustment plates 506 will change the shape and height of the support plane they jointly constitute. For the bending knife 202, the change of the lower support position and height will affect the stress and deformation path of the titanium alloy plate during the bending process, thereby realizing the adjustment of the bending arc. The change of the support position and height realizes automatic adjustment, effectively reducing the large amount of debugging time consumed by adjusting the bending arc under the traditional production method, optimizing the production process, avoiding frequent mold changes, and making the production process more continuous and efficient. During the entire movement of the moving plate 505, the electric telescopic rod 5011 is extended and retracted and the slide plate 5012 slides in the slide groove 5013, providing precise guidance for the connecting rod 507. As the connecting rod 507 rotates with the adjusting plate 506, its bottom can move along a predetermined track, ensuring that the rotation angle and position of the adjusting plate 506 meet the requirements, thereby ensuring the accuracy of the bending angle adjustment.

[0048] When the curvature of the bend is adjusted, the micro cylinder 303 is started, and its output end pushes the moving frame 304 to move. When the moving frame 304 is pushed by the micro cylinder 303, the sliders 1 305 at both ends of the outside slide on the inner wall of the adjustment plate 1 301. At the same time, the two connecting rods 1 306 on the outside of the moving frame 304 will rotate with the movement of the moving frame 304. The connecting rod 1 306 is connected to the connecting rod 2 307 through a rotating shaft. When the connecting rod 1 306 rotates, it will drive the connecting rod 2 307 to rotate, so that the slider 2 308 slides on the inner wall of the adjustment plate 2 309. Through such a connecting rod transmission mechanism, the linear motion of the moving frame 304 is converted into the lifting motion of the adjustment plate 2 309. The lifting motion of the adjustment plate 2 309 can change the height position of the top correction mechanism 4. In this way, the correction mechanism 4 can be adjusted to a suitable height according to the actual conditions such as the thickness of the titanium alloy plate.

[0049] When the position of the correction mechanism 4 is adjusted, the position of the movable sleeve 603 on the support rod 602 is loosened to drive the gas distribution pipe 608 to move, and then the movable sleeve 603 is fixed by tightening the tightening bolt 605, and then the position of the flame burning head 609 is adjusted. The flame can be accurately aimed at the part of the titanium alloy plate that needs to be heated. After the position of the flame burning head 609 is adjusted, the valve 6012 is opened, and the gas (such as fuel gas, etc.) in the gas storage box 6011 enters the gas distribution pipe 608 through the inlet pipe 1 606, the valve 6012, and the inlet pipe 2 607, and finally the flame is ejected from the flame burning head 609. The bent part of the titanium alloy plate that needs to be bent is heated by spraying flames from the flame burning head 609, and the opening of the valve 6012 can be controlled to adjust the gas flow rate, thereby controlling the size and intensity of the flame, and heating the titanium alloy plate to reduce its strength. The titanium alloy plate with reduced strength can better fit the shape of the bending mold during the bending process, greatly improving the bending accuracy and forming quality.

[0050] After heating, the titanium alloy plate passes through the two correction plates 406 and is placed on the two adjustment plates 506. The titanium alloy plate will exert pressure on the correction plate 406. After the correction plate 406 is subjected to pressure, it will move outward. At this time, the guide rod 403 slides at the internal through hole of the connecting block 402, and the correction spring 405 is compressed. The elastic force of the correction spring 405 will exert a reverse force on the correction plate 406, so that the correction plate 406 tightly clamps the titanium alloy plate. Correcting the position of the titanium alloy plate ensures that the titanium alloy plate is in the correct position before bending, and can control the relative position of the titanium alloy plate and the bending mold, effectively avoiding problems such as bending angle deviation and side length error caused by position deviation, thereby stably producing high-quality and high-precision products. The limit block 404 at one end of the guide rod 403 can prevent the guide rod 403 from escaping from the connecting block 402. When the titanium alloy plate is placed firmly, the moving seat 201 inside the bending machine body 2 drives the bending knife 202 to move downward, and the titanium alloy plate is bent.
