Description

Technical Field

[0002] At present, when processing the door panels of excavators, it is necessary to bend the door panels of the excavators. Door panel bending is an important part of sheet metal processing. Excavator door panels often need to have specific shapes according to design requirements, such as V-shape, U-shape, etc. Through bending, the cross-sectional shape and area of ​​the door panels will change, which helps to improve its strength and rigidity. For heavy equipment such as excavators, the structural strength of the door panels is crucial. It must be able to withstand various external forces and impacts to ensure the stability and safety of the equipment.

[0003] Existing door panel bending processing equipment is not convenient for adjusting the bending angle and bending position according to specific door panel processing requirements, which means that the equipment may not be able to adapt to excavator door panels of different sizes, shapes or material properties, thereby limiting its scope of application and flexibility. Due to the problem of adjustment adaptability, the equipment may not be able to efficiently complete the bending processing tasks of various door panels, resulting in low production efficiency or unstable processing quality.

[0014] A door panel bending process, comprising the steps of:

[0015] A: When the staff is bending the excavator door panel, the staff will place the excavator door panel to be processed on the top of the placing table. Before bending the excavator door panel on the placing table, the staff will first turn on the second motor according to the length of the excavator door panel. The output shaft of the second motor drives the first vacuum suction cups on both sides to move in opposite directions to move the first vacuum suction cups to a suitable position. Then the staff will turn on the first motor so that the mounting table drives the first vacuum suction cup below to slide left and right. According to the different bending positions this time, the position of the mounting table is adjusted. Then the staff will turn on the third motor so that the lifting frame pushes the electric slide to descend. The second vacuum suction cup contacts the excavator door panel below and adsorbs the excavator door panel through the second vacuum suction cup. Then the third motor moves the excavator door panel up through the second vacuum suction cup, and the electric slide is also opened so that the moving part below the electric slide drives the excavator door panel to move forward, so that the excavator door panel moves to the top of the bending pallet.

[0016] B: When the excavator door panel moves to the top of the bending pallet, the staff opens the hydraulic cylinders on both sides, so that the first vacuum suction cup descends and is fixed to the surface of the excavator door panel. At this time, the staff releases the adsorption of the second vacuum suction cup on the excavator door panel, and then the moving part under the electric slide controls the second vacuum suction cup to move back to its original position. The staff opens the cylinders on the front and rear sides, and the output shaft of the cylinder drives the connecting shaft to move up and down. The connecting plate pulls the bending pallets on both sides to move. According to the bending angle this time, the position of the bending pallets on both sides is adjusted. After the adjustment is completed, the staff rotates the knobs on the front and rear sides to make the positioning plate move on the surface of the bending pallet. According to the width of the excavator door panel, the position of the positioning plate is adjusted;

[0017] C: After the staff adjusts the position of the positioning plate, they can open the hydraulic cylinders on both sides. The output shaft of the hydraulic cylinder drives the lifting plate to descend, and the first vacuum suction cup under the mounting platform drives the excavator door panel to descend. When the excavator door panel descends, it will first contact the support plate. As the mounting platform continues to fall, the excavator door panel bends, and the mounting seat also tilts to a certain extent until the excavator door panel is bent. When the excavator door panel is bent, the positioning plates on the front and rear sides limit the excavator door panel to complete the bending operation of the excavator door panel. After the excavator door panel is bent, the staff can control the electric slide again and remove the excavator door panel from the top of the bending pallet through the second vacuum suction cup, and then the staff can continue with subsequent processing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can be precisely adjusted according to the bending angle, bending position and length of the door panel, so as to adapt to the processing needs of excavator door panels of different specifications and types. This high degree of adjustability and adaptability greatly improves the versatility and flexibility of the equipment, enabling it to handle more types of door panel processing tasks. Through precise adjustment and positioning functions, the equipment can ensure that the door panel remains stable and motionless during the bending process, thereby improving the accuracy and quality of the bending, which helps to reduce the scrap rate and rework rate, and improve production efficiency and economic benefits. In addition, the equipment is also convenient for loading and unloading operations, so that the operator can easily place the door panel on the equipment and process it, further improving the practicality of the equipment.

[0038] A door panel bending process, comprising the steps of:

[0039] A: When the staff is bending the excavator door panel, the staff will place the excavator door panel to be processed on the placing table 16. Before bending the excavator door panel on the placing table 16, the staff will first turn on the second motor 121 according to the length of the excavator door panel. The output shaft of the second motor 121 drives the first vacuum suction cups 15 on both sides to move in opposite directions to move the first vacuum suction cups 15 to a suitable position. Then the staff will turn on the first motor 101, so that the mounting table 9 drives the first vacuum suction cup 15 below to move to a suitable position. Slide left and right, and adjust the position of the mounting platform 9 according to the different bending positions. Then the staff turns on the third motor 182, so that the lifting frame 181 pushes the electric slide 19 down, and the second vacuum suction cup 20 contacts the excavator door panel below, and adsorbs the excavator door panel through the second vacuum suction cup 20.

[0040] B: When the excavator door panel moves to above the bending support plate 3, the staff opens the hydraulic cylinders 7 on both sides, so that the first vacuum suction cup 15 descends and is adsorbed and fixed to the surface of the excavator door panel. At this time, the staff releases the adsorption of the excavator door panel by the second vacuum suction cup 20, and then the moving part under the electric slide 19 controls the second vacuum suction cup 20 to move back to its original position. The staff opens the cylinders 42 on the front and rear sides, and the output shaft of the cylinder 42 drives the connecting shaft 44 to move up and down, and the connecting plate 45 pulls the bending support plates 3 on both sides to move. According to the bending angle of this time, the positions of the bending support plates 3 on both sides are adjusted. After the adjustment is completed, the staff rotates the knobs 54 on the front and rear sides to make the positioning plate 55 move on the surface of the bending support plate 3, and adjusts the position of the positioning plate 55 according to the width of the excavator door panel;

[0041] C: After the staff has adjusted the position of the positioning plate 55, they can open the hydraulic cylinders 7 on both sides. The output shaft of the hydraulic cylinder 7 drives the lifting plate 8 to descend, and the first vacuum suction cup 15 under the mounting platform 9 drives the excavator door panel to descend. When the excavator door panel descends, it will first contact the support plate 6. As the mounting platform 9 continues to fall, the excavator door panel is bent, and the mounting seat 14 is also tilted to a certain extent until the excavator door panel is bent. When the excavator door panel is bent, the positioning plates 55 on the front and rear sides limit the excavator door panel to complete the bending operation of the excavator door panel. After the excavator door panel is bent, the staff can operate the electric slide 19 again, and remove the excavator door panel from the top of the bending support plate 3 through the second vacuum suction cup 20, and then the staff can continue with subsequent processing.

10. A door panel bending process, applied to the door panel bending equipment according to claim 9, characterized in that: Includes steps: A: When the staff is bending the door panel of the excavator, the staff places the door panel to be processed on the placing table (16). Before the bending process of the door panel on the placing table (16), the staff first turns on the second motor (121) according to the length of the door panel of the excavator, and the output shaft of the second motor (121) drives the first vacuum suction cups (15) on both sides to move in opposite directions to move the first vacuum suction cups (15) to a suitable position. Then, the staff turns on the first motor (101), so that the mounting table (9) drives the first vacuum suction cup (15) below to move to a suitable position. Slide left and right, and adjust the position of the mounting platform (9) according to the different bending positions. Then the staff turns on the third motor (182), so that the lifting frame (181) pushes the electric slide (19) down, and the second vacuum suction cup (20) contacts the excavator door panel below, and the excavator door panel is adsorbed by the second vacuum suction cup (20). Then the third motor (182) moves the excavator door panel up through the second vacuum suction cup (20), and the electric slide (19) is also turned on, so that the moving part below the electric slide (19) drives the excavator door panel to move forward, so that the excavator door panel moves to the top of the bending support plate (3). B: When the door panel of the excavator moves to the top of the bending support plate (3), the staff opens the hydraulic cylinders (7) on both sides, thereby causing the first vacuum suction cup (15) to descend and be adsorbed and fixed to the surface of the door panel of the excavator. At this time, the staff releases the adsorption of the second vacuum suction cup (20) on the door panel of the excavator, and then the moving part under the electric slide (19) controls the second vacuum suction cup (20) to move back to its original position. The staff opens the cylinders (42) on the front and rear sides, and the output shaft of the cylinder (42) drives the connecting shaft (44) to move up and down. The connecting plate (45) pulls the bending support plates (3) on both sides to move. According to the bending angle of this time, the positions of the bending support plates (3) on both sides are adjusted. After the adjustment is completed, the staff rotates the knobs (54) on the front and rear sides to cause the positioning plate (55) to move on the surface of the bending support plate (3). According to the width of the door panel of the excavator, the position of the positioning plate (55) is adjusted; C: After the staff has adjusted the position of the positioning plate (55), they can open the hydraulic cylinders (7) on both sides. The output shaft of the hydraulic cylinder (7) drives the lifting plate (8) to descend, and the first vacuum suction cup (15) under the mounting platform (9) drives the excavator door panel to descend. When the excavator door panel descends, it will first contact the support plate (6). As the mounting platform (9) continues to fall, the excavator door panel is bent, and the mounting seat (14) also tilts to a certain extent until the excavator door panel is bent. When the excavator door panel is bent, the positioning plates (55) on the front and rear sides limit the excavator door panel to complete the bending operation of the excavator door panel. After the excavator door panel is bent, the staff can control the electric slide (19) again to remove the excavator door panel from the top of the bending support plate (3) through the second vacuum suction cup (20), and then the staff can continue with subsequent processing.
