Description

Technical Field

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

[0002] Under the pressure of the upper or lower die of the bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. At the beginning of plastic bending, the sheet is free to bend. As the upper or lower die applies pressure to the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other. At the same time, the curvature radius and the bending force arm also gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points. At this time, a V-shaped bend is completed, which is commonly known as bending.

[0036] like Figure 7 and Figure 8As shown, the extrusion positioning mechanism includes a second motor 27 installed on the top of the U-shaped block 2, and the relative inner walls of the U-shaped block 2 are provided with lifting grooves. The relative inner walls of the two lifting grooves are rotatably installed with threaded rods 28, one end of one threaded rod 28 is installed on the output shaft of the second motor 27, and the two threaded rods 28 are threadedly sleeved with threaded blocks 29. The sides of the two threaded blocks 29 are installed with lifting blocks 30. The tops of the two lifting blocks 30 are provided with lifting holes, and moving rods 31 are slidably installed on the two lifting holes. The bottom and top ends of the two moving rods 31 are respectively provided with positioning plates 32 and moving blocks 33.

The top of the U-shaped bottom plate 1 is provided with an extrusion hole adapted to the extrusion plate 37, and the two threaded rods 28 are installed in conjunction with the transmission assembly.

[0037] like Figure 7 As shown, the transmission assembly includes two transmission cavities provided 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, and the two ends of the movable rod 39 extend into the two transmission cavities respectively and are installed with second bevel gears 40, and the two first bevel gears 38 are respectively engaged with the two second bevel gears 40.

[0038] like Figure 1As shown, the pushing mechanism includes fixed plates 42 installed on the sides of both ends of the U-shaped block 2, and the sides of the two fixed plates 42 are installed with electric liquid pushing rods 43. The output ends of the two electric liquid pushing rods 43 are jointly installed with a movable plate 44, and the top of the movable plate 44 is installed with an L-shaped pushing plate 45 that is compatible with the pushing hole.

Two fixed threaded holes are provided on the top of the upper mold 5 and the bottom of the lower mold 7, and the ends of the four fixing bolts 8 are respectively threadedly installed in the two fixed threaded holes. The advantage of this arrangement is that through the arrangement of the fixing bolts 8, the upper mold 5 and the lower mold 7 are conveniently replaced, and the steel plate is conveniently bent to different degrees or to different degrees.

[0040] like Figure 1 As shown, an inclined block is installed on the top of the U-shaped base plate 1, and four supporting legs are installed on the bottom of the U-shaped base plate 1. The bottom of the four supporting legs is installed with a buffer pad. The advantage of this arrangement is that the setting of the supporting legs makes it easy to support the U-shaped base plate 1, and the setting of the buffer pad plays a certain buffering role, reducing the impact caused by vibration.

[0041] The working principle of the present invention is as follows: first, the steel plates are stacked in the placement box 41, and then placed on the U-shaped bottom plate 1 through an external sling. When they are placed, the two electric hydraulic push rods 43 are started by the PLC controller. The output of the two electric hydraulic 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 bottom steel plate to move, and then push the steel plate to the top of the movable block 13 and the placement plate 47. When the steel plate contacts the stopper 16, the steel plate is separated from the placement box 41. Then, the L-shaped push plate 45 is reset through the PLC controller. The reset of the L-shaped push plate 45 will cause the upper steel plate to fall under the action of gravity. Then, the first motor 9 is started by the PLC controller. The output of the first motor 9 will cause the steel plate therein to fall. A screw rod 10 rotates, and the rotation of one of the screw rods 10 will cause the other screw rod 10 to rotate through the sprocket 11 and the chain 12. The rotation of the two screw rods 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 with the placement plate 47. When the movable block 13 corresponds to the upper mold 5 and the lower mold 7, the first motor 9 is stopped and the second motor 27 is started through the PLC controller. 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 movable rod 39 to rotate through another first bevel gear 38 and another second bevel gear 40. When the other threaded rod 28 rotates, the rotation of the two threaded rods 28 will cause the threaded block 29 to descend, and the descending of the threaded block 29 will cause the lifting block 30 to descend, and the descending of the lifting block 30 will cause the moving rod 31 and the L-shaped moving plate 34 to descend, and the descending of the moving rod 31 and the L-shaped moving plate 34 will cause the positioning plate 32 and the extrusion plate 37 to descend. When the positioning plate 32 contacts the steel plate, the positioning plate 32 will be blocked by the moving rod 31 to cause the moving block 33 to rise, and the rising of the moving block 33 will give the L-shaped moving plate 34 a force toward the placement plate 47 through the inclined plate 35. The L-shaped moving plate 34 will slide under the action of the through rod, and the movement of the L-shaped moving plate 34 will cause the extrusion plate 37 to move, thereby fixing the steel plate from the top and the side. The PLC controller starts the cylinder 3, and 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 mold 5 to move downward, and the downward movement of the upper mold 5 will bend the steel plate through the lower mold 7. When the bending is completed, the second motor 27 will be reversed by the PLC controller first. The reverse output of the second motor 27 will cause the lifting block 30 to rise. The rising of the lifting block 30 will cause the positioning plate 32 to not contact the steel plate. At this time, the L-shaped movable plate 34 will be reset under the action of the return spring 36 when it is not subjected to force. The reset of the L-shaped movable plate 34 will cause the positioning plate 32 and the extrusion plate 37 to reset. When the positioning plate 32 and the extrusion plate 37 do not fix the steel plate, the first motor 9 will be output through the PLC controller, and 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, causing 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, thereby preventing the stopper 16 from blocking the steel plate. Then, the movable block 13 will continue to move. The movable block 13 continues to move, causing 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 rotates, which in turn moves the steel plate, causing it to fall into the external transfer device. When unloading is completed, the PLC controller controls the first motor 9 to output in the reverse direction. The reverse output of the first motor 9 resets the movable block 13. The reset of the movable block 13 resets 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 resets the stopper 16 and the paddle 22. The above operation is then repeated. As a result, the placement box 41 only needs to be loaded regularly, eliminating the need for workers to constantly perform loading and bending operations. This reduces the number of times workers carry out tasks, reduces their workload, and facilitates use.

[0042] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
