Technical Field
[0001] This utility model relates to the field of parts processing technology, specifically a precision roll forming equipment for high-efficiency heat insulation plates for aircraft wheel hubs. Background Technology
[0002] Aircraft wheel hubs are an important component of the aircraft landing gear system, used to support the tires and transfer loads. During aircraft landing, the friction between the brake discs and the tires can generate temperatures as high as 3000°C. Without effective heat insulation and cooling, the wheel hub material can deform or even melt, threatening flight safety. Heat insulation panels are an important protective component for aircraft wheel hubs, which can effectively reduce the temperature of the wheel hubs. Roll forming equipment is the main equipment for the production of heat insulation panels, which has advantages such as strengthening the strength of the panels, optimizing the stress of the panels, and high efficiency and low cost.
[0003] The aforementioned roll forming equipment still has some problems in use. Traditional roll forming equipment has a cutter at the exit position to cut the sheet material. Generally, the cutter directly contacts the formed sheet material to complete the cutting process. The sheet material is irregular in shape, and the pressure at the contact point between the sheet material and the cutter is high. As the cutter moves, the force on the cutting position of the sheet material becomes uneven. In severe cases, it may even lead to the deformation and scrapping of the sheet material. Therefore, in order to address the above problems, a precision roll forming equipment for high-efficiency heat insulation panels for aircraft wheel hubs is proposed. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, traditional roll forming equipment has a cutter at the exit position to cut the sheet material. Generally, the cutter directly contacts the formed sheet material to complete the cutting process. Since the sheet material is irregularly shaped, the pressure at the contact point between the sheet material and the cutter is high. As the cutter moves, the force at the cutting position of the sheet material becomes uneven. In severe cases, it may even lead to the deformation and scrapping of the sheet material. This utility model proposes a precision roll forming equipment for high-efficiency heat insulation panels for aircraft wheel hubs.
[0005] The technical solution adopted by this utility model to solve its technical problem is: the precision roll forming equipment for high-efficiency heat insulation plate of aircraft wheel hub of this utility model includes a base, a pair of support frames and guide plates are fixedly connected to the front end of the base, several pairs of shaping rollers are fixedly connected to the middle of the base, and a discharge frame is fixedly connected to the rear end of the base. A hydraulic cylinder is fixedly connected to the top of the discharge frame, and a discharge groove is provided through the inside of the discharge frame. The output end of the hydraulic cylinder is fixedly connected to a mounting plate, a lifting plate is provided below the mounting plate, and a positioning mechanism is provided at the upper end of the lifting plate.
[0006] Preferably, the positioning mechanism includes a knob, one end of which is fixedly connected to a bidirectional lead screw, and a pair of ball sliders are sleeved on the outer side of the bidirectional lead screw, with a positioning rod fixedly connected to the top surface of the ball sliders.
[0007] Preferably, a cutting groove is provided on the lower part of the mounting plate, the cutting groove is flush with one end of the discharge groove, and the top of the cutting groove is inclined.
[0008] Preferably, the knob and the bidirectional lead screw are both located at the upper end of the lifting plate, near the inside. The side of the knob passes through the lifting plate and is movably connected to the lifting plate. The positioning rod passes through the top surface of the lifting plate and is slidably connected to the lifting plate.
[0009] Preferably, the outer surface of the bidirectional lead screw is provided with rotating threads of the same length at both ends but opposite in direction, and the two rotating threads are respectively adapted to two ball sliders.
[0010] Preferably, a pair of connecting grooves are provided on one side of the mounting plate, and a positioning groove is provided inside the connecting groove, with the positioning rod being engaged with the positioning groove.
[0011] The advantages of this utility model are: 1. This utility model places the raw material roller between two support frames, so that one end of the raw material passes through the top surface of the guide plate and between several pairs of shaping rollers, and enters the discharge trough inside the discharge frame. The shaping roller is started to rotate, and the raw material is rolled and shaped. After shaping, the material passes through the discharge trough and the cutting trough. Since the cutting trough is flush with the discharge trough, when the material reaches the specified size, the cutting trough descends vertically, and the material is directly cut as a whole by the blade inside the cutting trough. This application sets a shaping and cutting component so that the size of the cutter is adapted to the heat insulation board, so that the material is subjected to uniform force and the effect of heat insulation board forming and cutting is improved. 2. This utility model, through the structural design of the positioning mechanism, moves the lifting plate horizontally to the inside of the discharge rack, whereupon the positioning rod enters the connecting groove. Rotating the knob drives the bidirectional lead screw to rotate, causing the two ball bearing sliders to move synchronously in opposite directions, which in turn drives the two positioning rods to move synchronously. The horizontal position of the positioning rod engages with the positioning groove, thus completing the installation of the lifting plate. Conversely, the positioning rod separates from the positioning groove, and then the lifting plate slides outward, causing the positioning rod to disengage from the connecting groove, completing the disassembly of the lifting plate. A pair of positioning components that can be adjusted synchronously in opposite directions are provided, facilitating the installation and disassembly of the cutting components, making it easier to replace the cutting components, and further facilitating the forming and cutting of the heat insulation board.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1 one Figure 6 As shown, a precision roll forming equipment for high-efficiency heat insulation plates for aircraft wheel hubs includes a base 1. A pair of support frames 2 and a guide plate 3 are fixedly connected to the front end of the base 1. Several pairs of shaping rollers 4 are fixedly connected to the middle of the base 1. A discharge frame 5 is fixedly connected to the rear end of the base 1. A hydraulic cylinder 6 is fixedly connected to the top of the discharge frame 5. A discharge groove 7 is provided through the interior of the discharge frame 5. The output end of the hydraulic cylinder 6 is fixedly connected to the mounting plate 8, and a lifting plate 9 is provided below the mounting plate 8. A positioning mechanism 11 is provided at the upper end of the lifting plate 9. During operation, traditional roll forming equipment has a cutter at the exit position to cut the sheet material. Generally, the cutter directly contacts the formed sheet material to complete the cutting process. Since the sheet material is irregularly shaped, the pressure on the upper part of the sheet material in contact with the cutter is high. As the cutter moves, the force on the cutting position of the sheet material becomes uneven. In severe cases, it may even lead to the deformation and scrapping of the sheet material. The hydraulic cylinder 6 is activated, which causes the mounting plate 8 to drive the lifting plate 9 to descend and cut the formed heat insulation sheet material.
[0017] Furthermore, the positioning mechanism 11 includes a knob 14, one end of which is fixedly connected to a bidirectional lead screw 15, and a pair of ball sliders 16 are sleeved on the outer side of the bidirectional lead screw 15. A positioning rod 17 is fixedly connected to the top surface of the ball sliders 16. During operation, the positioning mechanism 11 facilitates the installation and disassembly of the cutting parts, making it easier to replace the cutting parts later. Rotating the knob 14 drives the bidirectional lead screw 15 to rotate. The rotation of the bidirectional lead screw 15 causes the two ball sliders 16 to move synchronously in opposite directions, which in turn drives the two positioning rods 17 to move synchronously.
[0018] Furthermore, a cutting groove 10 is provided below the mounting plate 8. The cutting groove 10 is flush with one end of the discharge groove 7, and the top of the cutting groove 10 is inclined. During operation, the raw material roller is placed between two support frames 2, so that one end of the raw material passes through the top surface of the guide plate 3 and between several pairs of shaping rollers 4, and enters the discharge trough 7 inside the discharge frame 5. The shaping rollers 4 are started to rotate, and the raw material is rolled and shaped. After shaping, the material passes through the discharge trough 7 and the cutting groove 10. Since the cutting groove 10 is flush with the discharge trough 7, when the material reaches the specified size, the cutting groove 10 descends vertically, and the material is directly cut as a whole by the blade inside the cutting groove 10.
[0019] Furthermore, the knob 14 and the bidirectional lead screw 15 are both located at the upper end of the lifting plate 9, near the inside. The side of the knob 14 passes through the lifting plate 9, and the knob 14 is movably connected to the lifting plate 9. The positioning rod 17 passes through the top surface of the lifting plate 9, and the positioning rod 17 is slidably connected to the lifting plate 9. During operation, the lifting plate 9 is first moved horizontally to the inside of the discharge rack 5 so that the cutting groove 10 is aligned with the discharge groove 7. At the same time, the top of the lifting plate 9 is located below the mounting plate 8, and the positioning rod 17 enters the connecting groove 12. Then, when the positioning rod 17 moves, the horizontal position of the positioning rod 17 engages with the positioning groove 13, thereby completing the installation of the lifting plate 9.
[0020] Furthermore, the outer surface of the bidirectional lead screw 15 is provided with rotating threads of the same length at both ends but opposite in direction, and the two rotating threads are respectively adapted to the two ball sliders 16; During operation, the two ball sliders 16 move synchronously in opposite directions through two rotating threads, which in turn drives the positioning rod 17 to move, facilitating the installation and disassembly of the lifting plate 9.
[0021] Furthermore, a pair of connecting grooves 12 are provided on one side of the mounting plate 8, and a positioning groove 13 is provided inside the connecting groove 12. The positioning rod 17 is engaged with the positioning groove 13. During operation, the positioning rod 17 enters the mounting plate 8 through the connecting groove 12 to facilitate the movement of the lifting plate 9. Then, through the positioning groove 13, the positioning rod 17 is engaged with the mounting plate 8 during the movement, thus completing the installation of the lifting plate 9. Conversely, the positioning rod 17 separates from the positioning groove 13, and then the lifting plate 9 slides outward to disengage the positioning rod 17 from the connecting groove 12, thus completing the disassembly of the lifting plate 9.
[0022] Working principle: First, move the lifting plate 9 horizontally to the inside of the discharge rack 5 so that the cutting groove 10 is aligned with the discharge groove 7. At the same time, the top of the lifting plate 9 is below the mounting plate 8, and the positioning rod 17 enters the connecting groove 12. Rotate the knob 14 to drive the bidirectional lead screw 15 to rotate. The rotation of the bidirectional lead screw 15 causes the two ball sliders 16 to move synchronously in opposite directions, which in turn drives the two positioning rods 17 to move synchronously. Then the horizontal position of the positioning rod 17 engages with the positioning groove 13, thereby completing the installation of the lifting plate 9.
[0023] The raw material roller is placed between two support frames 2, so that one end of the raw material passes through the top surface of the guide plate 3 and between several pairs of shaping rollers 4, and enters the discharge trough 7 inside the discharge frame 5. The shaping rollers 4 are started to rotate, and the raw material is rolled and shaped. After shaping, the material passes through the discharge trough 7 and the cutting groove 10. Since the cutting groove 10 is flush with the discharge trough 7, when the material reaches the specified size, the cutting groove 10 descends vertically. The material is directly cut as a whole through the blade inside the cutting groove 10, so the material is subjected to uniform force and the effect of heat insulation board forming and cutting is improved.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
