Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, and in particular to a generator set base bending processing device. Background Technology

[0002] As a core load-bearing component supporting the entire unit (such as a steam turbine or generator), the generator set base must possess high strength, high rigidity, and precise assembly dimensions. Its structure is mostly made of thick steel plates through multiple bending processes, directly affecting the operational stability of the generator set. With the upgrading of new energy (wind power and photovoltaic supporting facilities) and the power industry, generator sets are developing towards larger sizes and customization, which places stringent requirements on the diversity of base specifications, bending precision, and production efficiency.

[0003] Traditional bending equipment typically uses a fixed height and angle for its support platform, which cannot accommodate the bending requirements of steel plates of different thicknesses. When bending thick steel plates, the fixed support is prone to causing the material to be suspended due to the mismatch between the support height and the plate thickness, resulting in wrinkles or localized plastic deformation. During the bending process, the material undergoes dynamic deformation as the upper die presses down, and the fixed angle support cannot synchronously conform to the lower surface of the material, resulting in large fluctuations in the springback amount, requiring subsequent manual adjustment. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned generator set base bending processing device, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a generator set base bending processing device, which has dynamic support adjustment, automated feeding, parameterized adaptation and closed-loop control, thereby improving product accuracy, reducing labor costs and shortening changeover time.

[0034] Example 1

[0035] Reference Figure 1-3This is the first embodiment of the present invention, which provides a generator set base bending processing device, the device comprising,

[0036] The bending assembly 100 includes a bending machine host 101, a guide rail 102 fixedly connected to the working area of ​​the bending machine host 101, and a forming die 103 adapted to be installed on the side wall of the guide rail 102.

[0037] The bending assembly 100 is used to bend the base material, providing bending power and forming reference. The main bending machine 101 can dynamically adjust the pressure according to the base thickness (e.g., 300t pressure for a 50mm thick steel plate) to avoid material overload cracking or angle deviation caused by underpressure. The displacement sensor built into the main machine monitors the downward distance of the upper die (the bending cutter that cooperates with the forming die) in real time to ensure consistent pressure reduction for each bend. The guide rail 102 in the working area is a high-precision linear guide rail (parallelism error ≤0.02mm / m). The bottom of the forming die 103 is slidably connected to the guide rail via a slider, and the locking bolts on its side wall can be locked after position adjustment (to prevent displacement during bending). The working curved surface of the forming die is customized according to the base bending angle (90° / 135° / 150°, etc.), and the radius of curvature matches the steel plate thickness (e.g., R15mm curved surface for a 10mm steel plate to prevent cracks during bending). The surface is chrome-plated (hardness HRC50-55) to reduce wear and extend service life.

[0038] During use, the parameters of the base to be processed—thickness (e.g., 5mm), bending angle (e.g., 90°), and length (e.g., 3m)—are input into the control system. The system automatically matches the bending pressure (200t), forming mold number (90° curved surface), and support parameters. The forming mold 103 is slid along the guide rail 102 until its bending baseline is aligned with the centerline of the upper mold of the bending machine (calibrated using a laser alignment instrument; deviation ≤0.1mm). The locking bolts on the side wall of the forming mold are then tightened for fixation.

[0039] In summary, it is adaptable to different thicknesses and bending angles, and can be bent according to the actual length of the sheet material, which can meet the processing requirements of generator set bases with different power. When changing models, there is no need to replace the core components, the debugging time is short, and the equipment changeover cost is saved.

[0040] Example 2

[0041] Reference Figure 1-7 This is the second embodiment of the present invention, which differs from the first embodiment in that it provides a support assembly 200 for a generator set base bending processing device.

[0042] The support assembly 200 includes a support base 201 inserted into the side wall of the bending machine main body 101, a support column 202 fixedly connected to the side wall of the support base 201, a support rod 203 inserted into the end of the support column 202, a fixing plate 204 fixedly connected to the end of the support rod 203, and a support plate 205 hinged to the end of the fixing plate 204. The end of the fixing plate 204 extends to the lower side wall of the forming mold 103.

[0043] The support component 200 adapts to the material bending deformation process through real-time adjustment of height and angle and flexible support. The support base 201 is connected to the side wall of the bending machine main unit 101 via a plug-in connection (it can slide along the length of the main unit to adapt to bases of different lengths). The support column 202 on its side wall has a square hollow structure (with built-in guide groove). The support rod 203 (square solid rod) is inserted into the support column and its rotation is restricted by the guide groove to ensure no swaying during lifting. The fixed plate 204 and the support plate 205 are hinged by a high-strength pin (20mm in diameter, heat-treated). A self-lubricating bearing (friction coefficient ≤0.01) is installed at the hinge to ensure smooth rotation without jamming.

[0044] Specifically, the support assembly 200 also includes a housing 206 fixedly connected to the side wall of the support plate 205, a floating plate 207 movably inserted into the inner wall of the housing 206, and a conveyor belt 208 rotatably installed on the side wall of the floating plate 207. The upper end face of the housing 206 is flush with the upper end face of the support plate 205, and the upper end face of the conveyor belt 208 is higher than the upper end face of the floating plate 207. A support plate 209 is fixedly connected inside the housing 206, and a lifting cylinder 210 is fixedly connected in the middle of the support plate 209. The output shaft end of the lifting cylinder 210 is fixedly connected to the bottom of the floating plate 207. A guide post 210a is fixedly connected to the bottom of the floating plate 207, and the lower end of the guide post 210a is inserted into the side wall of the support plate 209.

[0045] The support plate has a housing 206 (500mm long, 300mm wide) at its end, which houses a floating plate 207 (with a gap of ≤0.5mm between the floating plate and the inner wall of the housing). A conveyor belt 208 (200mm wide, made of wear-resistant rubber, with a surface texture depth of 1mm to increase friction) is installed on the upper surface of the floating plate. The conveyor belt is driven by a built-in motor (speed adjustable from 0-500rpm). Four sets of lifting cylinders 210 (50mm diameter, 50mm stroke) are fixed on the support plate 209 (10mm thick steel plate) at the bottom of the housing. The cylinder piston rods are connected to the bottom of the floating plate through flanges, and the guide posts 210a (20mm diameter, chrome-plated) at the four corners of the floating plate are inserted into the guide holes of the support plate (fitting clearance 0.02mm). When the cylinders extend or retract, the floating plate drives the conveyor belt to rise and fall smoothly: when it rises, the conveyor belt is 5mm higher than the support block (for easy material transport); when it falls, the conveyor belt is level with the upper surface of the support block (to share the material when bending, avoiding localized deformation).

[0046] Preferably, the support assembly 200 further includes a lever 211 fixedly connected to the side wall of the end connecting shaft of the support plate 205, and a sensor mounting plate 212 fixedly connected to the side wall of the fixing plate 204. The end of the lever 211 extends to the side wall of the sensor mounting plate 212, and the side wall of the sensor mounting plate 212 is provided with an arc-shaped mounting groove that cooperates with the lever 211.

[0047] Among them, the connecting shaft (coaxial with the hinge pin) at the end of the support plate 205 has a fixed lever 211 (150mm long, made of aluminum alloy) on its side wall, and a magnet is installed at its end; three sets of Hall sensors (15° apart) are fixed on the sensor mounting plate 212 (arc groove radius 200mm) on the side wall of the fixed plate 204, which can detect the position of the lever in real time. When the support plate rotates, the lever 211 drives the magnet to trigger different sensors and feed back the angle signal to the control system (error ≤0.5°), forming a "detection-feedback-adjustment" closed loop to ensure that the angle adjustment is synchronized with the material deformation.

[0048] It should be noted that a fixed seat 213 is fixedly connected to the side wall of the fixed plate 204, and a connecting rod 214 is rotatably mounted on the side wall of the fixed seat 213. A support rod 215 is hinged to the end of the connecting rod 214, and the end of the support rod 215 is rotatably connected to the lower side wall of the support plate 205. A drive motor 216 is fixedly connected to the middle position of the fixed plate 204. A reducer 217 is connected to the end of the output shaft of the drive motor 216 through a coupling. The reducer 217 is fixedly connected to the inner wall of the fixed seat 213, and the output shaft of the reducer 217 is fixedly connected to the end of the connecting rod 214.

[0049] The fixing seat 213 inside the fixing plate is a box-type structure, which houses a drive motor 216 (stepper motor, step angle 1.8°) and a reducer 217 (reduction ratio 1:100). The output shaft of the reducer 217 is connected to a connecting rod 214 (300mm long, high-strength alloy steel) via a flat key. The other end of the connecting rod 214 is hinged to a support rod 215 (200mm long) via a fisheye bearing. The end of the support rod is connected to the ear plate at the lower end of the support plate via a bearing seat, forming a four-bar linkage of "motor-reduction-connecting rod-support rod". When the drive motor 216 rotates the connecting rod 214 clockwise by 30°, the support rod pushes the support plate to rotate upward by 20° around the hinge axis (transmission ratio 1:0.67). The adjustment range covers 0° (horizontal support) to 90° (vertical support), which can match the deformation angle of the material during bending in real time (e.g., when bending from 0° to 90°, the support plate rotates synchronously from 0° to 90°, always in contact with the lower surface of the material).

[0050] Specifically, the support assembly 200 also includes a lifting motor 218 fixedly connected to the side wall of the support base 201, a gear 219 adapted to be installed at the end of the output shaft of the lifting motor 218, and a rack plate 220 fixedly connected to the side wall of the support rod 203. The side wall of the gear 219 meshes with the rack plate 220, and the side wall of the rack plate 220 slides in contact with the side wall of the support column 202.

[0051] The lifting motor 218 (servo motor, 1500 rpm) at the top of the support base drives the gear 219 (3mm module, 20 teeth) through a reducer (reduction ratio 1:50). The gear meshes with the rack plate 220 (tooth pitch 9.42mm) on the side wall of the support rod, forming a "motor-reduction-gear rack" transmission chain. For every revolution of the motor, the support rod rises and falls by 0.188mm, achieving a height adjustment of 0.01mm. This ensures that the height difference between the upper surface of the fixed plate 204 and the upper surface of the forming mold is equal to the material thickness (e.g., a height difference of 20mm ± 0.02mm for a 20mm thick steel plate), preventing tilting when the material is placed.

[0052] Furthermore, a support block 205a is threadedly connected to the upper end of the support plate 205. A ball bearing 205b is rotatably installed inside the support block 205a. The side wall of the support block 205a has an arc-shaped edge structure that cooperates with the ball bearing 205b. The upper end of the ball bearing 205b protrudes from the upper surface of the support block 205a. The support blocks 205a are evenly distributed on the upper surface of the support plate 205.

[0053] Among them, 20-30 sets of support blocks 205a (100mm apart) are evenly distributed on the upper surface of the support plate 205. Each set of support blocks has 3 balls 205b (10mm in diameter, made of bearing steel) inside. The balls protrude 1mm from the upper surface of the support block, and the arc edge (15mm radius) of the side wall of the support block fits with the outer circle of the ball, ensuring that the ball can only roll in the material conveying direction (restricting lateral movement). This reduces the frictional resistance when the material slides (the coefficient of friction is reduced from 0.3 to 0.05) and avoids the material from deflecting to the side.

[0054] During use, the control system drives the lifting motor 218, which, through gear 219 and rack plate 220, raises the support rod 203 to the target height (the height difference between the upper surface of the fixed plate 204 and the upper surface of the forming mold = material thickness 20mm). The guide column 210a ensures no swaying during the lifting process, and the motor self-locks after height calibration. The drive motor 216 drives the support plate 205 to rotate to 0° (horizontal state) through connecting rod 214 and support rod 215. The lever 211 triggers the 0° position sensor on the sensor mounting plate 212, and the system records the initial angle. Under the balance of gravity and the friction of the pad rubber, the material slowly slides towards the support plate 205—during this process, the end of the frame is aligned with the front end of the support plate (gap ≤ 5mm) to avoid material jamming.

[0055] When the material tip contacts the support plate, the control system triggers the extension of the lifting cylinder 210, and the floating plate 207 drives the conveyor belt 208 to rise 5mm above the support block. At the same time, the conveyor belt starts (speed 100mm / s) to transport the material towards the forming mold. The ball bearings 205b of the support block 205a slide and rotate with the material, reducing frictional resistance. When the material bending line (300mm from the end) reaches above the forming mold, the conveyor belt stops, the lifting cylinder 210 shortens, and the floating plate descends until the conveyor belt is level with the support block—the material falls completely onto the support block and the conveyor belt, achieving horizontal support (positioning accuracy ±0.5mm).

[0056] The upper die of the bending machine descends to the material surface at a speed of 50 mm / s (pausing at a distance of 1 mm), and is slightly pre-pressed (pressure 5t) to fix the material and prevent it from slipping during bending.

[0057] The control system presets the angle change curve of the support plate 205 based on the bending angle (90°) (which rotates synchronously with the downward movement of the upper die). The drive motor 216 drives the support plate to rotate from 0° through the linkage-support mechanism. When the upper die moves down 10mm (the material begins to bend), the support plate rotates to 30°, fitting against the lower surface of the bent material. When the upper die moves down to the target position (bending angle 90°), the support plate rotates synchronously to 90°, always providing close support to the material (avoiding wrinkles caused by suspension). During the process, the lever 211 triggers the sensor in real time, feeding back the angle signal to the system. If the deviation is >1°, the system automatically fine-tunes the motor speed to correct it. After the upper die reaches the target position, it holds pressure for 3 seconds (to eliminate material springback). At this time, the forming die cooperates with the upper die to bend the material to 90°. The ball bearings 205b of the support block roll slightly with the material deformation, ensuring that there is no hard friction in the support.

[0058] After the pressure holding period, the upper mold moves upward to its initial position at a speed of 100 mm / s, detaching from the material. Support reset: The drive motor 216 reverses, causing the support plate 205 to rotate from 90° back to 0°. The lever 211 triggers the 0° sensor and stops. The lifting cylinder 210 extends again, and the conveyor belt starts (running in reverse), transporting the bent base to the discharge area (or manually hoisting it), completing the single-piece processing.

[0059] In summary, the synchronous angle adjustment (error ≤ 0.5°) and precise height control (± 0.02 mm) of the support plate, which adapts to material deformation, solves the problems of inconsistent bending springback and surface wrinkles caused by traditional fixed supports. This ensures that the bending angle tolerance of the base is controlled within ± 1° and the dimensional deviation is ≤ 0.5 mm, meeting the assembly accuracy requirements of the generator set base (fitting clearance ≤ 1 mm). The hydraulic drive of the feeding assembly, the automatic positioning of the conveyor belt, and the parameterized adjustment of the support assembly enable a reduced-manpower operation from "feeding-processing-discharging" (only one person is needed to monitor a batch of 30 pieces). The rubber material of the pad and the ball bearing design of the support block reduce the scratch rate during material transfer from the traditional 15% to less than 1%. The chrome-plated curved surface of the forming mold makes smooth contact with the material, avoiding indentations during bending and reducing subsequent grinding processes. With a thickness adaptability of 10-50mm, an angle adjustment of 0°-90°, and a length coverage of 2-5m, it can meet the processing needs of generator set bases with different power (100kW-10MW). There is no need to replace the core components when changing models, and the debugging time is ≤30 minutes, saving 60% of the changeover cost compared with traditional special equipment.

[0060] Example 3

[0061] Reference Figure 1-3 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides a feeding assembly 300 for a generator set base bending processing device.

[0062] The feeding assembly 300 includes a bracket 301 inserted into the side wall of the support base 201, a frame 302 hinged to the end side wall of the bracket 301, a pad 303 fixedly connected to the side wall of the frame 302, and a fixing post 304 fixedly connected to the side wall of the bracket 301. The end of the frame 302 is snapped into the end of the fixing post 304, and the end of the frame 302 extends to the side wall of the support plate 205.

[0063] Among them, the bracket 301 (square steel welded structure, load-bearing capacity ≥5t) on the side wall of the support base 201 is connected to the support base by a pin (which can be quickly disassembled). The frame 302 (rectangular frame, 3m long and 1.5m wide) at its end is connected to the bracket by a hinge. The ear plate welded to the side wall of the frame is hinged to the hydraulic rod 305 (cylinder diameter 80mm, stroke 300mm). When the hydraulic rod 305 extends or retracts, it can drive the frame 302 to rotate around the hinge (adjustment range 0°-45°): when horizontal (0°), it is used to support the stacked materials; when tilted (10°-30°), it uses gravity to slide the materials toward the support plate. Four sets of pads 303 (1m long, 0.2m wide, made of rubber, Shore hardness 60°) are symmetrically distributed on the upper surface of the frame 302 to avoid hard contact that could scratch the steel plate surface; four sets of casters (with braking function, load capacity 1.5t / each) are installed at the bottom of the support, which can push the feeding component to move flexibly in the workshop (turning radius ≤1.5m) to adapt to different stacking areas; the U-shaped groove at the end of the frame can be snapped into the fixed column 304 (50mm in diameter) on the side wall of the support, and locked with bolts after snapping to ensure that the frame does not shake during feeding (displacement ≤0.5mm).

[0064] Specifically, a hydraulic rod 305 is hinged to the side wall of the bracket 301, and the end of the hydraulic rod 305 is rotatably mounted on the end side wall of the frame 302. A caster wheel is adapted to be installed at the bottom of the bracket 301.

[0065] When the hydraulic rod 305 extends or retracts, it can drive the frame 302 to rotate around the hinge (adjustment range 0°-45°): when horizontal (0°), it is used to support the stacked materials, and when tilted (10°-30°), it uses gravity to slide the materials toward the support plate.

[0066] Furthermore, the pads 303 are symmetrically arranged on the side wall of the frame 302, and the surface of the pads 303 is fitted with rubber pads. The end of the frame 302 is fixedly connected with a baffle 306 that works in conjunction with the pads 303.

[0067] Among them, the baffle 306 (0.1m high, 10mm thick steel plate) at the end of the frame 302 is perpendicular to the surface of the frame and can position the bending line when it is attached to the end of the material (the distance between the baffle and the forming mold is equal to the extension length of the material before bending, with an error of ≤1mm).

[0068] In use, push the feeding assembly (with brake) to the material stacking area, adjust the frame 302 to 0° (horizontal), and manually or with a forklift place the steel plate to be processed on the pad 303, with the end of the material in contact with the baffle 306 (positioning the bending line). Material sliding: Unlock the frame and the fixed column 304, activate the hydraulic rod 305 to extend, and drive the frame to rotate to a 15° tilt angle. Under the balance of gravity and the friction of the pad rubber, the material slowly slides towards the support plate 205, with the end of the frame aligned with the front end of the support plate (gap ≤ 5mm) to avoid material jamming.

[0069] In summary, the hydraulically driven conveying of the feeding assembly replaces manual material handling, allowing the metal sheet to be bent to be directly moved onto the support assembly in front of the bending machine. This prevents the sheet from deforming due to uneven stress caused by manual handling, reduces the labor intensity of workers, and ensures safe bending.
