Description

Technical Field

[0001] This invention relates to the field of sheet metal equipment technology, specifically to a sheet metal equipment and processing method for metal sheets with adjustable bending curvature. Background Technology

[0002] In the field of sheet metal processing, the bending process has a crucial impact on product quality and precision. However, existing bending equipment still faces many unresolved issues in practical applications. Specifically, the contact area between the bending components and the sheet metal in traditional equipment is relatively small. Under the same pressure, the concentrated force easily leads to indentations on the sheet metal surface, severely affecting the product's appearance and subsequent performance.

[0003] More importantly, the bending process and curvature detection of existing equipment are often disconnected. Post-bending curvature detection relies heavily on manual or offline methods, failing to provide real-time feedback on bending accuracy. If a deviation from the preset curvature is detected, the machine must be stopped to adjust parameters or even reprocessed, resulting in low production efficiency and high rework rates. Furthermore, if the sheet metal is not securely fixed during bending, displacement can easily occur, further exacerbating curvature deviations, increasing scrap rates, and severely restricting the quality and efficiency of sheet metal processing.

[0004] Therefore, the development of sheet metal bending equipment that can flexibly adjust the bending radius, reduce sheet metal indentations, and achieve real-time detection and dynamic adjustment linkage has become an urgent need in the industry. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet metal processing equipment and method with adjustable bending curvature to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Sheet metal equipment includes a support frame, a clamping device, a feeding device, a testing device, and a bending device. The support frame is connected to the clamping device, the feeding device, the testing device, and the bending device. The clamping device and the feeding device are located on the same straight line, and the testing device is connected to the bending device.

[0008] The support frame serves as the main mounting base for the installation and support of other components. The sheet metal is placed on the pushing device, which then feeds it into the clamping device. After the clamping device clamps the sheet metal, the bending device bends it. The bending angle is then detected by a detection device. When the bending angle deviates from the predetermined value, the detection device controls the bending device to adjust the bending force, thereby adjusting the bending angle.

[0009] Furthermore, the bending device includes a support plate, bending hydraulic cylinders, and bending fasteners. The support plate is connected to the detection device. There are two bending hydraulic cylinders, which are slidably connected to the support plate. The output ends of the two bending hydraulic cylinders are fastened to the bending fasteners.

[0010] The support plate serves as the main mounting base for the installation and support of other components. The bending hydraulic cylinder provides downward pressure to the bending fastener, ensuring sufficient pressure for the sheet metal to bend. Simultaneously, the displacement output by the bending hydraulic cylinder causes the bending fastener to slide on the support plate, thereby allowing the bending fastener to adjust the curvature of the sheet metal.

[0011] Furthermore, the bending fastener includes a bending block, a support block, a movable plate, a first threaded rod, a fixed sleeve, a bending pressure plate, and a first return spring. The output end of the bending hydraulic cylinder is fastened to the bending block, and the bending block is fastened to the support block. The bending block has several movable plates that are slidably connected to the bending block. The movable plates have a first threaded rod that is threadedly connected to the first threaded rod. The fixed sleeve has a through hole, and the first threaded rod is placed inside the through hole and rotatably connected to the through hole. The bending pressure plate has a second threaded rod that is rotatably connected to the bending pressure plate. The second threaded rod is placed inside the fixed sleeve and rotatably connected to the fixed sleeve. The second threaded rod is threadedly connected to the first threaded rod. A first return spring is provided outside the first threaded rod and is fastened to the fixed sleeve. The end of the first return spring away from the fixed sleeve is fastened to the movable plate. A second return spring is provided on the bending pressure plate and is fastened to the bending pressure plate. The end of the second return spring away from the bending pressure plate is fastened to the fixed sleeve.

[0012] The bending block serves as the primary mounting base for supporting and installing other components. When sheet metal bending is required, two bending hydraulic cylinders output force to move the bending block. This movement of the bending block drives the support block and bending pressure plate to move until the bending pressure plate exerts force on the sheet metal. The sheet metal then exerts force on the bending pressure plate, causing the bending pressure plate to exert force on the second return spring, compressing the spring. Simultaneously, the bending pressure plate exerts force on the second threaded rod, causing it to rotate. This rotation of the second threaded rod drives the first threaded rod to rotate, which in turn moves the moving plate. As the moving plate moves, it exerts pressure on the first return spring, causing the first return spring to compress. Depending on the magnitude of the force exerted by the bending pressure plate on the sheet metal, the moving distance of the moving plate gradually increases. The movement of the moving plate weakens the middle support structure of the bending pressure plate, causing the bending pressure plate to produce an arc, thereby increasing the contact area between the bending pressure plate and the sheet metal. This disperses the force on the sheet metal, reducing the possibility of indentations caused by insufficient force area during bending. When bending is no longer required, the first and second return springs release elastic potential energy to reset the bending pressure plate and the moving plate.

[0013] Furthermore, the bending block is provided with an inclined surface, the support block is fastened to the inclined surface, the moving plate is slidably connected to the inclined surface, and the second return spring is fastened to the inclined surface.

[0014] By setting an inclined plane, the bending pressure plate makes a certain angle when it comes into contact with the sheet metal, which increases the contact area between the bending pressure plate and the sheet metal, thereby reducing the formation of creases under the same pressure.

[0015] Furthermore, the detection device includes a detection cylinder, a fixed rod, a rotating motor, a fixed cylinder, and a detection rod. There are two detection cylinders, which are slidably connected to a support plate. The output end of the detection cylinder is fixedly connected to the rotating motor, the output end of the rotating motor is fixedly connected to the fixed rod, the fixed rod is fixedly connected to the fixed cylinder, and the output end of the fixed cylinder is fixedly connected to the detection rod. The detection rod has a mounting cavity, which contains a detection coil, a detection spring, a detection magnet, and a roller. The detection coil is fixedly connected to the mounting cavity, the detection spring is fixedly connected to the mounting cavity, the detection magnet is placed inside the detection coil, the detection magnet is fixedly connected to the detection spring, and the end of the detection magnet away from the detection spring is fixedly connected to the roller.

[0016] The detection cylinder, as the main driving device, drives the rotary motor to move. The displacement output of the detection cylinder drives the rotary motor, which in turn moves the fixed rod. The fixed rod then moves the fixing cylinder, which in turn moves the detection rod until it reaches the designated position on the sheet metal, compressing the detection spring and causing the roller to contact the sheet metal. The mounting cavity in the detection rod serves as the main mounting base for positioning other components. When the bending radius detection begins, the rotary motor outputs torque to rotate the fixed rod, which in turn drives the fixing cylinder. The rotation of the fixed cylinder drives the detection rod to rotate, which in turn causes the roller to rotate. When the roller rotates and encounters a change in curvature, the pressure exerted by the sheet metal on the roller changes, causing the roller to move. The movement of the roller causes the detection magnet to move, which in turn causes a change in the magnetic flux within the detection coil, generating an induced current. The electrical signal generated by this induced current is then used to adjust the bending curvature of the sheet metal via a bending pressure plate. Simultaneously, the movement of the detection magnet causes a change in the elastic potential energy of the detection spring. When it is necessary to reset the roller, the elastic potential energy of the detection spring is released to reset the roller.

[0017] Furthermore, the propulsion device includes a propulsion plate and a propulsion cylinder, the output ends of the propulsion plate and the propulsion cylinder are fastened together, the propulsion plate and the support frame are slidably connected, and the propulsion cylinder and the support frame are fastened together.

[0018] The push plate serves as the main mounting base for positioning other components. When the sheet metal needs to be pushed forward, the push plate is moved within the support frame by the output of the push cylinder. The movement of the push plate causes the sheet metal on it to move until it enters the clamping device. The clamping device then presses the sheet metal to prevent it from moving during bending and causing changes in curvature.

[0019] Furthermore, the clamping device includes a clamping motor, a rotating plate, a clamping plate, and a fixed plate. The clamping motor and the support frame are fastened together. The output end of the clamping motor and the rotating plate are fastened together. The rotating plate and the clamping plate are fastened together. The fixed plate and the support frame are fastened together.

[0020] The fixed plate serves as the main support base for supporting the sheet metal. When the sheet metal needs to be pressed, the torque output by the pressing motor drives the rotating plate to move. The movement of the rotating plate drives the pressing plate to move, thereby pressing the sheet metal on the fixed plate and preventing the sheet metal from moving.

[0021] Furthermore, a processing method for a sheet metal equipment with adjustable bending radius includes the following steps:

[0022] S1. Place the sheet metal into the working position of the pushing device and the clamping device, then push it a set distance through the pushing device, and at the same time fix the sheet metal through the clamping device;

[0023] S2. After the pressing is completed, the sheet metal is bent by a bending device. After the sheet metal is bent once, the curvature of the sheet metal is detected by a detection device.

[0024] S3. When the sheet metal curvature does not reach the predetermined value, the bending force of the bending device is adjusted according to the detection result of the detection device, thereby adjusting the sheet metal curvature.

[0025] S4. After bending, remove the bent sheet metal and place the unprocessed sheet metal inside. Repeat the above steps.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. Reduce sheet metal indentations and protect surface quality. In bending fasteners, the bending pressure plate and the moving plate are linked by a threaded rod and a return spring. When the bending pressure plate contacts the sheet metal, the reaction force of the sheet metal pushes the bending pressure plate to compress the second return spring, simultaneously driving the second threaded rod to rotate, which in turn drives the first threaded rod to rotate, causing the moving plate to slide along the inclined surface of the bending block and compress the first return spring. During this process, the movement of the moving plate weakens the middle support structure of the bending pressure plate, causing the bending pressure plate to adapt to the curvature of the sheet metal, increasing the contact area with the sheet metal, dispersing the bending force, significantly reducing indentations caused by force concentration, and protecting the integrity of the sheet metal surface.

[0028] 2. Flexible adjustment of bending arc to adapt to diverse needs: The bending device adopts two sliding bending hydraulic cylinders. By adjusting the position of the hydraulic cylinders on the support plate, the action point of the bending fastener can be directly changed to achieve initial adjustment of the bending arc. At the same time, the adaptive deformation capability of the bending pressure plate further refines the arc adjustment accuracy. It can adapt to bending requirements of different arcs without changing the mold, thus improving the versatility and adjustment efficiency of the equipment.

[0029] 3. Real-time detection and closed-loop adjustment improve bending accuracy. The detection device achieves curvature detection through the rolling contact between the detection rod and the sheet metal: the roller moves the detection magnet within the detection coil as the sheet metal curvature changes, changing the coil's magnetic flux and generating an induced current. The current signal provides real-time feedback of the bending curvature data. If the detected curvature deviates from the preset value, the system can immediately adjust the output force or position of the bending hydraulic cylinder, achieving "detection-adjustment" closed-loop control, significantly improving bending accuracy and reducing rework rate.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example: Figures 1-7 As shown, this invention provides a sheet metal processing equipment and method with adjustable bending radius. The sheet metal equipment includes a support frame 1, a pressing device 2, a pushing device 3, a detection device 4, and a bending device 5. The support frame 1 is connected to the pressing device 2, the pushing device 3, the detection device 4, and the bending device 5. The pressing device 2 and the pushing device 3 are located on the same straight line, and the detection device 4 is connected to the bending device 5.

[0040] The support frame 1 serves as the main mounting base for the installation and support of other components. The sheet metal is placed on the pushing device 3, and then the pushing device 3 sends the sheet metal into the clamping device 2. After the clamping device 2 clamps the sheet metal, the bending device 5 bends the sheet metal. Then, the detection device 4 detects the bending angle of the sheet metal. When the bending arc of the sheet metal is detected to deviate from the predetermined value, the detection device 4 controls the bending device 5 to adjust the bending force, thereby adjusting the bending arc.

[0041] like Figure 1 , Figure 3 and Figure 4As shown, the bending device 5 includes a support plate 51, a bending hydraulic cylinder 52, and a bending fastener 53. The support plate 51 is connected to the detection device 4. There are two bending hydraulic cylinders 52, which are slidably connected to the support plate 51. The output ends of the two bending hydraulic cylinders 52 are fastened to the bending fastener 53.

[0042] The support plate 51 serves as the main mounting base for the installation and support of other components. The bending hydraulic cylinder 52 provides downward pressure to the bending fastener 53, so that the bending fastener 53 has sufficient pressure to bend the sheet metal. At the same time, the bending hydraulic cylinder 52 outputs displacement to drive the bending fastener 53 to slide on the support plate 51, thereby allowing the bending fastener 53 to adjust the curvature of the sheet metal.

[0043] like Figures 4-6 As shown, the bending fastener 53 is provided with a bending block 531, a support block 532, a moving plate 533, a first threaded rod 534, a fixed sleeve 535, a bending pressure plate 536, and a first return spring 537. The output end of the bending hydraulic cylinder 52 is fastened to the bending block 531, and the bending block 531 is fastened to the support block 532. The bending block 531 is provided with several moving plates 533, which are slidably connected to the bending block 531. The moving plates 533 are provided with the first threaded rod 534, which is threadedly connected to the moving plates 533. The fixed sleeve 535 is provided with a through hole 5351, in which the first threaded rod 534 is placed and rotatably connected to the through hole 5351. The bending pressure plate 536... A second threaded rod 538 is provided on the upper part of the bending pressure plate 536. The second threaded rod 538 is rotatably connected to the bending pressure plate 536. The second threaded rod 538 is placed inside the fixed sleeve 535. The second threaded rod 538 and the fixed sleeve 535 are rotatably connected. The second threaded rod 538 and the first threaded rod 534 are threadedly connected. A first return spring 537 is provided outside the first threaded rod 534. The first return spring 537 is fastened to the fixed sleeve 535. The end of the first return spring 537 away from the fixed sleeve 535 is fastened to the moving plate 533. A second return spring 539 is provided on the bending pressure plate 536. The second return spring 539 is fastened to the bending pressure plate 536. The end of the second return spring 539 away from the bending pressure plate 536 is fastened to the fixed sleeve 535.

[0044] The bending block 531 serves as the main mounting base for supporting and installing other components. When sheet metal bending is required, the two bending hydraulic cylinders 52 output force to move the bending block 531. The movement of the bending block 531 drives the support block 532 and the bending pressure plate 536 to move until the bending pressure plate 536 exerts a force on the sheet metal. Then, the sheet metal exerts a force on the bending pressure plate 536, causing the bending pressure plate 536 to exert a force on the second return spring 539, compressing the second return spring 539. Simultaneously, the bending pressure plate 536 exerts a force on the second threaded rod 538, causing the second threaded rod 538 to rotate. The rotation of the second threaded rod 538 drives the first threaded rod 534 to rotate, which in turn drives... The movable plate 533 moves, and while moving, it exerts pressure on the first return spring 537, causing the first return spring 537 to compress. Depending on the magnitude of the force exerted by the bending pressure plate 536 on the sheet metal, the moving distance of the movable plate 533 gradually increases. The movement of the movable plate 533 weakens the middle support structure of the bending pressure plate 536, causing the bending pressure plate 536 to have an arc, thereby increasing the contact area between the bending pressure plate 536 and the sheet metal. This disperses the force on the sheet metal, reducing the possibility of indentations caused by insufficient force area during bending. When bending is no longer required, the elastic potential energy is released by the first return spring 537 and the second return spring 539 to reset the bending pressure plate 536 and the movable plate 533.

[0045] like Figure 5 and Figure 6 As shown, the bending block 531 is provided with an inclined surface 5311, the support block 532 is fastened to the inclined surface 5311, the moving plate 533 is slidably connected to the inclined surface 5311, and the second reset spring 539 is fastened to the inclined surface 5311.

[0046] By setting the inclined surface 5311, the bending pressure plate 536 has a certain angle when it contacts the sheet metal, which increases the contact area between the bending pressure plate 536 and the sheet metal, thereby reducing the formation of creases under the same pressure.

[0047] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the detection device 4 includes a detection cylinder 41, a fixed rod 42, a rotating motor 43, a fixed cylinder 44, and a detection rod 45. There are two detection cylinders 41, which are slidably connected to the support plate 51. The output end of the detection cylinder 41 is fastened to the rotating motor 43, the output end of the rotating motor 43 is fastened to the fixed rod 42, the fixed rod 42 is fastened to the fixed cylinder 44, and the output end of the fixed cylinder 44 is fastened to the detection rod 45. The detection rod 45 has a mounting cavity 451, which contains a detection coil 452, a detection spring 453, a detection magnet 454, and a roller 455. The detection coil 452 is fastened to the mounting cavity 451, the detection spring 453 is fastened to the mounting cavity 451, the detection magnet 454 is placed inside the detection coil 452, the detection magnet 454 is fastened to the detection spring 453, and the end of the detection magnet 454 away from the detection spring 453 is fastened to the roller 455.

[0048] The detection cylinder 41, as the main driving device, drives the rotary motor 43 to move. The displacement output of the detection cylinder 41 drives the rotary motor 43 to move, which in turn drives the fixed rod 42 to move. The fixed rod 42 then drives the fixed cylinder 44 to move, which in turn drives the detection rod 45 to move until the detection rod 45 reaches the designated position on the sheet metal, compressing the detection spring 453 and causing the roller 455 to contact the sheet metal. The mounting cavity 451 in the detection rod 45 serves as the main mounting base for positioning other components. When the bending radius detection begins, the rotary motor 43 outputs torque to rotate the fixed rod 42, which in turn drives the fixed cylinder 44 to rotate, thus fixing the spring 45. The rotation of cylinder 44 drives the rotation of detection rod 45, which in turn causes roller 455 to rotate. When roller 455 rotates and its curvature changes, the pressure exerted by the sheet metal on roller 455 changes, causing roller 455 to move. The movement of roller 455 drives detection magnet 454 to move, which in turn causes a change in the magnetic flux in detection coil 452, generating an induced current in detection coil 452. The electrical signal generated by this induced current is used to adjust the bending curvature of the sheet metal through bending pressure plate 536. At the same time, the movement of detection magnet 454 causes a change in the elastic potential energy of detection spring 453. When it is necessary to reset roller 455, the elastic potential energy of detection spring 453 is released to reset roller 455.

[0049] like Figure 1 and Figure 2 As shown, the propulsion device 3 includes a propulsion plate 31 and a propulsion cylinder 32. The output ends of the propulsion plate 31 and the propulsion cylinder 32 are fastened together. The propulsion plate 31 and the support frame 1 are slidably connected. The propulsion cylinder 32 and the support frame 1 are fastened together.

[0050] The push plate 31 serves as the main mounting base for positioning other components. When the sheet metal needs to be pushed, the push cylinder 32 drives the push plate 31 to move within the support frame 1. The movement of the push plate 31 causes the sheet metal on it to move until it moves into the clamping device 2. The clamping device 2 then clamps the sheet metal to prevent it from moving during bending and causing changes in curvature.

[0051] like Figure 1 and Figure 2 As shown, the clamping device 2 includes a clamping motor 21, a rotating plate 22, a clamping plate 23, and a fixed plate 24. The clamping motor 21 is fastened to the support frame 1. The output end of the clamping motor 21 is fastened to the rotating plate 22. The rotating plate 22 is fastened to the clamping plate 23. The fixed plate 24 is fastened to the support frame 1.

[0052] The fixed plate 24 serves as the main support base for supporting the sheet metal. When the sheet metal needs to be pressed, the pressing motor 21 outputs torque to drive the rotating plate 22 to move. The movement of the rotating plate 22 drives the pressing plate 23 to move, thereby pressing the sheet metal on the fixed plate 24 with the pressing plate 23 to prevent the sheet metal from moving.

[0053] like Figures 1-7 As shown, a processing method for a sheet metal equipment with adjustable bending radius includes the following steps:

[0054] S1. Place the sheet metal into the working position of the pushing device and the clamping device 2, then push it a set distance by the pushing device 3, and at the same time fix the sheet metal by the clamping device 2;

[0055] S2. After the pressing is completed, the sheet metal is bent by the bending device 5. After the sheet metal is bent once, the curvature of the sheet metal is detected by the detection device 4.

[0056] S3. When the sheet metal curvature does not reach the predetermined value, the bending force of the bending device 5 is adjusted according to the detection result of the detection device 4, thereby adjusting the sheet metal curvature.

[0057] S4. After bending, remove the bent sheet metal and place the unprocessed sheet metal inside. Repeat the above steps.

[0058] The working principle of this invention: The support frame 1 serves as the main mounting base for the installation and support of other components. Sheet metal is placed on the pushing device 3, which then feeds it into the clamping device 2. The clamping device 2 clamps the sheet metal, and two bending hydraulic cylinders 52 output force to move the bending block 531. The movement of the bending block 531 drives the support block 532 and the bending pressure plate 536 to move until the bending pressure plate 536 exerts force on the sheet metal, causing the bending pressure plate 536 to bend. When the curvature of the bending pressure plate 536 needs to be detected, the rotating motor 43 outputs torque to rotate the fixing rod 42. The rotation of the fixing rod 42... The rotating fixed cylinder 44 drives the detection rod 45 to rotate, which in turn causes the roller 455 to rotate. When the roller 455 rotates and encounters a change in curvature, the pressure exerted by the sheet metal on the roller 455 changes, causing the roller 455 to move. The movement of the roller 455 drives the detection magnet 454 to move, which in turn causes a change in the magnetic flux in the detection coil 452, resulting in an induced current in the detection coil 452. The curvature of the sheet metal is detected by the signal value of the induced current. When the sheet metal bending curvature deviates from the predetermined value, the detection device 4 controls the bending device 5 to adjust the bending force, thereby adjusting the bending curvature.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
