[0001] The present invention relates to the technical field of automated bending equipment, in particular to a plate processing and automatic bending production equipment capable of turning over a plate. Background Art

[0002] With the development of numerical control technology and automation technology in the sheet metal bending production process, automatic bending production equipment realizes automated operation through numerical control technology (CNC), and can accurately and quickly bend metal sheets according to preset parameters. It is a high-efficiency production equipment for metal sheets.

[0003] However, in actual use of existing automatic bending production equipment, when the plate needs to be flipped for bending processing, the automatic feeding mechanism in the existing automatic bending production equipment can only perform horizontal rotation adjustment of the plate, feeding and precise feeding operations. When the bending position of the plate is long and the bending angle of the plate is large after bending, such bent plates need to be withdrawn from the mold and flipped in many steps, resulting in the automatic feeding mechanism in the existing automatic bending production equipment being inconvenient to complete the flipping and feeding of the plate by adding a single flipping device. The flipping processing of the bent plate still requires manual or multi-axis robotic arm equipment to cooperate to complete the flipping of the plate, resulting in high cost of automatic bending production equipment when using multi-axis robotic arm equipment for flipping, and low efficiency when manually flipping. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic bending production equipment for plate processing that can be flipped to solve the problems raised by the above-mentioned background technology.

[0006] Preferably, balls are distributed in an array on the top of the installation box, and the balls on the top of the installation box are used for sliding of the plate. The rotating plate and the tops of the convex surfaces on the left and right sides of the installation box are in the same horizontal plane as the tops of the balls.

[0007] Preferably, the flip assembly includes a limiting slide groove, which is opened on the upper part of the mounting frame, and a mounting block is slidably connected in the limiting slide groove, and the right side protrusion of the mounting block is connected to a gear disk 1 through a servo motor, and a rack 1 is engaged below the gear disk 1, and the rack 1 is fixed to the right side of the mounting frame, and the left side of the mounting block is rotatably connected to a rotating column through a bearing, and a gear disk 2 is fixed on the outside of the rotating column, and a rack 2 is slidably engaged above the gear disk 2, and the rack 2 is fixed in a groove on the left front side of the mounting frame, and a fixing bar is fixed to the left end of the rack 2.

[0008] Preferably, the initial position of the mounting block is located behind the limiting sliding groove, and the left side of the rotating column is installed on the rear side of the fixing bar.

[0009] Preferably, the rack 2 is used for the gear disc 2 to rotate 180 degrees, and is arranged above the sliding path of the gear disc 2.

[0010] Preferably, the clamping assembly includes a sliding groove three, which is opened on the left side of the fixing strip, and two clamping strips are slidably connected to the front and rear sides of the sliding groove three through a threaded groove rod three.

[0011] Preferably, the thread groove rod 1, the thread groove rod 2 and the thread groove rod 3 are all driven by a servo motor.

[0012] Preferably, the front and rear sections of the threaded groove on the threaded groove rod three are arranged oppositely, and the threaded groove rod three is used for relative movement of the two clamps.

[0014] The present invention drives the slide plate, the mounting frame and the mounting box to move rightward in the base frame to unload the plate, and cooperates with the clamping assembly to make the two clamping bars move relative to each other when the threaded groove rod rotates, thereby completing the centering positioning and clamping operation of the bent plate. Cooperating with the flipping assembly, when the mounting block moves in the limiting slide groove once, the gear disc 2 engages and rotates with the rack 2, driving the rotating column and the fixed bar to rotate synchronously, completing a 180-degree same-position flip of the plate in the two clamping bars, thereby adding the function of clamping and flipping the plate in the same position to the automatic feeding mechanism in the existing automatic bending production equipment.

[0015] The present invention is provided with a slide, a No. 1 electric push rod, a No. 2 electric push rod and a fixed column. When the mold in the bending mechanism is reset, the bending position of the plate is long, the bending angle of the plate is large, and it is inconvenient for the plate to be horizontally withdrawn and flipped, the No. 1 electric push rod, the No. 2 electric push rod and the fixed column are first used to adjust the corresponding positions of the mounting frame and the mounting box in the base frame through the bending parameters of the plate in the system in the controller to complete the withdrawal of the bent plate in the two clamps in the mold. At the same time, before the plate is flipped, the No. 1 electric push rod is moved down and the No. 2 electric push rod is moved up to adjust the mounting frame and the mounting box to the right tilt accordingly, and then the flip assembly and the clamping assembly are turned in conjunction to complete the flipping and feeding of the plate, so that the flipping mechanism in the automatic feeding mechanism can complete the flipping of plates with different bending parameters, further improving the controllability and adaptability when the bent plate is flipped.

[0035] When the plate needs to be flipped during the bending process, after the upper mold in the bending mechanism 1 is reset, the controller first turns on the motor connected to the threaded groove rod three 162 through the flipping program, driving the two clamping strips 163 to move relative to each other in the slide groove three 161, and clamping the plate accordingly according to the width of the plate, and then turns on the servo motor connected to the threaded groove rod one 4, so that the threaded groove rod one 4 rotates to drive the slide plate 5 to move to the right in the slide groove one 3 to the maximum position, and then the controller starts the servo motor connected to the gear plate one 143. When the gear plate one 143 rotates to engage the rack one 144, it drives the mounting block 142 to slide to the front side of the limiting slide groove 141 to the maximum position. In this process, the plates in the two clamping strips 163 are driven to move synchronously through the rotating column 145 and the fixed bar 15. During this movement, when the gear plate two When 146 moves to the meshing position of rack 2 147, rack 2 147 drives gear disc 2 146 and rotating column 145 to rotate, so that fixed bar 15 flips backward 180 degrees, completing the flipping operation of the plates in the same position of the two clamping bars 163, and then the servo motor connected to the thread groove rod 1 4 is turned on, so that the thread groove rod 1 4 rotates and drives the slide plate 5 to reset to the left in the slide groove 1 3, and then the motor connected to the thread groove rod 3 162 is turned on to drive the two clamping bars 163 to reset in the slide groove 3 161, completing the flipping and resetting feeding of the bent plate, and then through the bending parameters in the system in the controller mentioned above, the servo motor connected to the thread groove rod 2 11 and the rotating plate 13 is turned on, and the corresponding parameters of the slide 12 and the rotating plate 13 are adjusted to complete the automatic bending and feeding after the plate is flipped;
