DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technical staff in the art without creative work fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a bending machine with a continuous bending function, including an operating table 1, columns 2 are welded at both ends of the surface of the operating table 1, a left fixed seat 3 and a right fixed seat 4 are respectively provided below the columns 2, the left fixed seat 3 is connected to the surface of the operating table 1 by bolts, a translation lead screw 5 is rotatably connected inside the column 2, one end of the translation lead screw 5 is connected to a hydraulic cylinder 6 by a nut provided on its surface through a bolt, the other end of the hydraulic cylinder 6 is connected to a pressing block 7 by a bolt, the pressing block 7 is located above the left fixed seat 3 and the right fixed seat 4, a moving upright frame 8 is slidably connected to one end of the operating table 1, the moving upright frame 8 is on the same side as the left fixed seat 3, and the moving upright frame 8 is connected to a displacement sensor 10 through an electric telescopic rod 9 provided on its surface.
[0024] A driving bevel gear 301 is rotatably connected inside the left fixed seat 3, the driving bevel gears 301 are connected to each other by a shaft rod penetrating through their axles, the driving bevel gears 301 are respectively meshed with driven bevel gears 302, lifting lead screws 303 are respectively installed at the axles of the driven bevel gears 302, and both ends of a limiting plate 304 are welded to the lifting lead screws 303 through nuts provided on their surfaces.
[0025] The right fixed seat 4 is slidably connected to the surface of the operating table 1 through a right fixed seat driving block 401 provided at its bottom, a driving rod 402 penetrates through the inside of the right fixed seat driving block 401, and the driving rod 402 is rotatably connected to the inside of the operating table 1.
[0026] In this embodiment, as Figure 1 and Figure 2 shown, the bottom of the pressing block 7 is arc-shaped, and the pressing block 7 forms a lifting structure through the hydraulic cylinder 6, and the pressing block 7 forms a horizontal transmission structure between the left fixed seat 3 and the right fixed seat 4 through the translation lead screw 5; the shape of the pressing block 7 can apply pressure to the material below through the push of the hydraulic cylinder 6 to complete the purpose of material bending. Compared with the current static single-point detection method on the material surface, by using the translation lead screw 5, the pressing block 7 can be tested at different points in the same plane of the material through the transmission structure. Through this continuous pressing, the change of the bending degree in this plane can be comprehensively understood, and the bending characteristics of the material at different positions can be understood, so as to better simulate the complex stress conditions that the material may encounter in actual use and improve the true reliability of the detection data.
[0027] In this embodiment, as Figure 3As shown in the figure, the lifting lead screw 303 forms a transmission structure through the driving bevel gear 301 and the driven bevel gear 302. The limiting plate 304 is slidably connected to the concave surface area inside the left fixing seat 3 through the nut on the surface of the lifting lead screw 303. And an elastic element 305 made of rubber is glued to the bottom of the limiting plate 304. At present, most bending devices do not have the function of clamping materials and need to install fixtures separately to fix the materials. Due to the problem of inconvenient adjustment caused by incompatibility with the equipment, the left fixing seat 3 and the right fixing seat 4 adjust the height of the limiting plate 304 through the internal structure. Therefore, when detecting materials, it is not limited by the thickness of the materials. And the elastic element 305 on the surface of the limiting plate 304 is made of rubber and has a certain anti-slip performance and elastic telescopic characteristics, which can adapt to the shape of the material surface and fit with it, and has good clamping performance for circular or flat materials.
[0028] In this embodiment, as Figure 4 shown, the internal structure of the right fixing seat 4 is the same as that of the left fixing seat 3. One end of the driving rod 402 passes through the surface of the operating table 1, and the other end of the driving rod 402 is threadedly connected to the inner wall of the operating table 1 through the threaded column opened on the surface of the shaft head. The right fixing seat 4 can change its working position on the surface of the operating table 1 through the right fixing seat driving block 401 at the bottom and adjust the distance between it and the left fixing seat 3. For some materials with smaller specifications during detection, the flexibility of the adjustment method improves the accuracy of the equipment during the detection process. And a strip-shaped notch is opened on the inner wall of the operating table 1, and through holes corresponding to the driving rod 402 are distributed on the inner wall of the notch to ensure that the right fixing seat 4 is fixed in the most convenient way after the position adjustment is completed.
[0029] In this embodiment, as Figure 5 shown, the displacement sensor 10 is slidably connected to the surface of the moving stand 8 through the electric telescopic rod 9, and a docking head 11 is rotatably connected to the surface of the displacement sensor 10. When the displacement sensor 10 (GC05 - 30W) is at the same horizontal position as a certain point on the material surface, when the material is pressed and bent by the pressing block 7, the point will displace, and the displacement sensor 10 will reflect the change in the bending degree through the displacement change of the point relative to its initial position. Compared with directly using a bending degree sensor, it can also monitor the displacement information of relevant position parts at the same time, providing additional data parameters. And the displacement sensor 10 can adjust the working height through the electric telescopic rod 9 to adapt to different specifications of materials and keep a horizontal position with the material surface in this adjustment method. And the docking head 11 at its front end increases the connection method for quickly docking with the surface of the object.
[0030] In this embodiment, as Figure 1As shown in the figure, a PLC controller 12 is provided on one side of the operating table 1, and the PLC controller 12 is electrically connected to the displacement sensor 10; the PLC controller 12 (model HY6A-6MR-4.3) is electrically connected to the displacement sensor 10, the electric telescopic rod 9 and the servo motor on the surface of the equipment. Through precise control, the detection process is realized with less manual intervention, improving the convenience of the detection process.
[0031] The usage method and advantages of the present utility model: For the bending machine with continuous bending function, during use, the working process is as follows:
[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, first, the tester places the bottom of the material to be tested in the concave surface area of the left fixing seat 3 and the right fixing seat 4. If the material specification is too small, the driving rod 402 can be rotated, and then the right fixing seat 4 is slid to the left fixing seat 3 side by sliding. After that, the driving rod 402 is reversed again to be threadedly fixed on the inner wall of the operating table 1, so that the right fixing seat 4 is fixed on the surface of the operating table 1. According to the thickness of the material, the servo motor drives the driving bevel gear 301 inside the left fixing seat 3 and the right fixing seat 4 to rotate, and then the driven bevel gear 302 rotates, so that the lifting lead screw 303 adjusts the limiting plate 304 through the nut on the surface during rotation. The limiting plate 304 fits on the surface of the material. The electric telescopic rod 9 is pushed or contracted to make the detection port of the displacement sensor 10 at the same horizontal position as the surface of the material. The docking head 11 at the front end serves the purpose of quickly docking with the surface of the object. After the material is fixed, the hydraulic cylinder 6 pushes the pressing block 7 to squeeze the surface of the material. The displacement sensor 10 will convert this displacement amount into an electrical signal and transmit it to the PLC controller 12 through the displacement change of this point relative to its initial position. After receiving the signal, the PLC controller 12, which is a mature device in the prior art, will process and analyze the signal according to the preset algorithm accordingly, so as to calculate the value of the bending degree. And the PLC controller 12 will send a command signal to the servo motor that drives the translation lead screw 5. The translation lead screw 5 makes the pressing block 7 perform extrusion at another point on the surface of the material under the transmission structure. The parameter acquisition of this point can be achieved by sliding the moving vertical frame 8 to make the displacement sensor 10 obtain the displacement parameter again. This structure can detect at different points on the surface of the material, effectively avoiding the one-sidedness caused by a single position, thereby improving the comprehensiveness of the detection structure.
[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments.
