Description

Technical Field

[0001] The present invention relates to the technical field of steel plate bending equipment, and particularly relates to a steel plate bending auxiliary equipment. Background Art

[0002] Under the pressure of the upper die or the lower die of a bending machine, a metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is freely bent. As the upper die or the lower die presses on the sheet, the sheet gradually presses against the inner surface of the V-shaped groove of the lower die. At the same time, the radius of curvature and the bending moment arm also gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points. At this time, a V-shaped bend is completed, which is commonly known as bending.

[0036] like Figure 7 As shown, the transmission assembly includes two transmission cavities opened on the U-shaped plate 6, the bottom ends of the two threaded rods 28 extend into the two transmission cavities respectively and are installed with first bevel gears 38, and the side inner walls of the two transmission cavities are jointly provided with a transmission hole, and a movable rod 39 is rotatably installed on the transmission hole.

[0039] As Figure 1 shown, an inclined block is installed on the top of the U-shaped bottom plate 1, and four support legs are installed on the bottom of the U-shaped bottom plate 1. Buffer pads are installed on the bottoms of the four support legs. The advantage of this setting is that through the setting of the support legs, it is convenient to support the U-shaped bottom plate 1, and through the setting of the buffer pads, it plays a certain buffering role and reduces the influence caused by vibration.

[0040] Working principle of the present invention: First, stack the steel plates in the placement box 41, and then place them on the U-shaped bottom plate 1 through an external lifting tool. When they are placed, start two electric push rods 43 through the PLC controller. The outputs of the two electric push rods 43 will cause the movable plate 44 to move. The movement of the movable plate 44 will cause the L-shaped push plate 45 to move. The movement of the L-shaped push plate 45 will cause the bottommost steel plate to move, thereby pushing the steel plate to the tops of the movable block 13 and the placement plate 47. When the steel plate contacts the stopper 16, at this time the steel plate disengages from the placement box 41. Then, through the PLC controller, make the L-shaped push plate 45 reset. The reset of the L-shaped push plate 45 will cause the upper steel plate to fall under the action of gravity. Then, start the first motor 9 through the PLC controller. The output of the first motor 9 will cause one of the lead screws 10 to rotate. The rotation of one of the lead screws 10 will cause the other lead screw 10 to rotate through the sprocket 11 and the chain 12. The rotation of the two lead screws 10 will cause the movable block 13 to move through the guide rod. The movement of the movable block 13 will cause the steel plate to move together in cooperation with the placement plate 47. When the movable block 13 corresponds to the upper die 5 and the lower die 7, at this time, through the PLC controller, first make the first motor 9 stop output, and then start the second motor 27. The output of the second motor 27 will cause one of the threaded rods 28 to rotate. The rotation of one of the threaded rods 28 will cause the movable rod 39 to rotate through one of the first bevel gears 38 and one of the second bevel gears 40. The rotation of the movable rod 39 will cause the other threaded rod 28 to rotate through the other first bevel gear 38 and the other second bevel gear 40. The rotation of the two threaded rods 28 will cause the threaded block 29 to descend. The descent of the threaded block 29 will cause the lifting block 30 to descend. The descent of the lifting block 30 will cause the moving rod 31 and the L-shaped moving plate 34 to descend. The descent of the moving rod 31 and the L-shaped moving plate 34 will cause the positioning plate 32 and the pressing plate 37 to descend. When the positioning plate 32 contacts the steel plate, at this time the positioning plate 32 will be blocked and cause the moving block 33 to rise through the moving rod 31. The rise of the moving block 33 will give the L-shaped moving plate 34 a force towards the placement plate 47 through the inclined plate 35. The L-shaped moving plate 34 will slide under the action of the through rod when it is stressed. The movement of the L-shaped moving plate 34 will cause the pressing plate 37 to move, thereby fixing the steel plate from the top and side. When it is fixed, start the cylinder 3 through the PLC controller. The output of the cylinder 3 will move downward through the mounting plate 4. The downward movement of the mounting plate 4 will cause the upper die 5 to move downward. The downward movement of the upper die 5 will bend the steel plate through the lower die 7. When the bending is completed, first make the second motor 27 output in the reverse direction through the PLC controller. The reverse output of the second motor 27 will cause the lifting block 30 to rise. The rise of the lifting block 30 will cause the positioning plate 32 not to contact the steel plate. At this time, the L-shaped moving plate 34 will be reset under the action of the return spring 36 when it is not stressed. The reset of the L-shaped moving plate 34 will cause the positioning plate 32 and the pressing plate 37 to reset. When the positioning plate 32 and the pressing plate 37 do not fix the steel plate, then make the first motor 9 output through the PLC controller. The output of the first motor 9 will cause the movable block 13 to continue to move.The movement of the movable block 13 will cause the stopper 16 and the first trapezoidal block 17 to move through the slider 14. When the first trapezoidal block 17 contacts the second trapezoidal block 19, the movable block 13 continues to move to cause the first trapezoidal block 17 to move downward. The downward movement of the first trapezoidal block 17 will cause the stopper 16 to move downward through the slider 14, so that the stopper 16 does not block the steel plate, and then the movable block 13 continues to move. The movable block 13 continues to move to cause the L-shaped baffle 26 to move through the push block 46. The movement of the L-shaped baffle 26 will cause the rack 24 to move. The movement of the rack 24 will cause the rotating rod 20 to rotate through the circular gear 23. The rotation of the rotating rod 20 will cause the L-shaped rotating plate 21 to rotate. The rotation of the L-shaped rotating plate 21 will The paddle 22 is rotated, and the rotation of the paddle 22 will paddle the steel plate, thereby causing the steel plate to fall into the external transfer device. When the unloading is completed, the first motor 9 is reversely output through the PLC controller, and the reverse output of the first motor 9 will reset the movable block 13. The reset of the movable block 13 will reset the slider 14 and the rack 24 under the action of the reset spring 15 and the extrusion spring 25. The reset of the slider 14 and the rack 24 will reset the block 16 and the paddle 22, and then repeat the above operation, so that it is only necessary to load the placement box 41 regularly, and the staff does not need to perform the loading and bending operation all the time, and the number of times the staff carry the materials is reduced, so that the work intensity is reduced, and it is easy to use.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
