Description

Technical Field

[0001] This invention relates to the technical field of bending machines, and in particular to a large bending machine. Background Technology

[0002] A bending machine is a machine that can bend sheet metal. It is widely used in sheet metal processing, metal manufacturing and other industries. Existing bending machines, such as the large sheet metal bending machine disclosed in the invention patent with announcement number CN113477758B and the large sheet metal double linkage bending machine disclosed in the invention patent with announcement number CN106862325B, can all bend sheet metal.

[0003] However, during use, it was found that the existing bending machine has a relatively simple structure. When bending thicker steel plates at right angles, the stress concentration is too large, which can easily reduce the strength of the bending position or even cause cracking. In addition, because the steel plate is thick, the bending position is prone to springback after bending, which affects the bending accuracy and results in poor practicality. Therefore, it is urgent to improve the existing equipment to solve the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a large bending machine that places a sheet metal on a bending mechanism, uses a grooving mechanism to groove the area to be bent to reduce the thickness of the area to be bent, then uses the bending mechanism to bend the grooved area, and finally uses a filling mechanism to fill the gap at the bending area with the waste material generated from grooving, thereby improving the practicality of the equipment.

[0005] The present invention provides a large bending machine, including a bending mechanism; it also includes a grooving mechanism and a filling mechanism, both of which are mounted on the bending mechanism;

[0006] The grooving mechanism grooves the sheet material, the bending mechanism bends the sheet material, and the filling mechanism fills the grooved area of ​​the sheet material.

[0007] The sheet material is placed on the bending mechanism, and the grooving mechanism grooves the area to be bent, reducing the thickness of the area. Then, the bending mechanism bends the grooved area, and the filling mechanism uses the waste material generated from grooving to fill the gap at the bending area, thereby improving the practicality of the equipment.

The sheet metal is placed on the multiple sets of casters, and the third hydraulic cylinder extends to press the lower pressure seat down onto the top of the sheet metal. Then, the second motor is turned on, and the lower pressure seat rotates the sheet metal on the multiple sets of casters through the meshing of the first gear and the gear ring, adjusting the angle of the sheet metal. Afterward, the operator transports the sheet metal with the adjusted angle to the right side of the workbench, and then the multiple sets of fourth hydraulic cylinders retract to place the sheet metal on the third bending die, thereby improving the practicality of the equipment.

[0010] Preferably, the grooving mechanism includes a second slide rail, a first electric slider, a third slide rail, a second electric slider, a grooving machine, a grooving cutter, and a cleaning mechanism.

The cleaning mechanism is installed at the top of the top plate. The height of the grooving cutter is adjusted by sliding the first electric slider on the second slide rail. Then, the second electric slider slides on the third slide rail while the grooving machine is turned on, causing the grooving cutter to rotate. The rotating grooving cutter grooves the area of ​​the plate that needs to be bent. At the same time, the cleaning mechanism collects the debris generated during grooving, thereby improving the practicality of the equipment.

The mixed gas is then ejected through the bottom of the jet pipe to cool the grooving cutter and to spit the debris generated during the grooving process perpendicular to the rear side of the grooving cutter. Then, the third slide rail is opened to discharge the air from the filter box, creating a negative pressure environment inside the filter box.

The molten steel remains in the conveying pipe and is discharged through multiple sets of discharge pipes at the bottom of the conveying pipe.

[0043] The sheet material is placed on multiple sets of casters 21. The third hydraulic cylinder 14 extends, causing the lower pressure seat 15 to press down on the top of the sheet material. Then, the second motor 17 is activated, and through the meshing of the first gear 18 and the gear ring 16, the lower pressure seat 15 drives the sheet material to rotate on the casters 21, adjusting the angle of the sheet material. Afterwards, the worker transports the angled sheet material to the right side of the workbench 1. The first motor 6 is activated, and through the lead screw 7, the first slider 5 slides on the first slide rail 4, moving the support frame 9 laterally. Then, through the extension of multiple sets of first hydraulic cylinders 8, the first bending die 10, in conjunction with the third bending die 13, clamps the sheet material.

Together with the first bending die 10 and the third bending die 13, the plate is bent to 80°-85°.

[0048] The sheet material is placed on multiple sets of casters 21. The third hydraulic cylinder 14 extends, causing the lower pressure seat 15 to press down on the top of the sheet material. Then, the second motor 17 is activated, and through the meshing of the first gear 18 and gear ring 16, the lower pressure seat 15 drives the sheet material to rotate on the casters 21, adjusting the angle of the sheet material. Afterwards, the worker transports the angled sheet material to the right side of the workbench 1. The first motor 6 is activated, and through the lead screw 7, the first slider 5 slides on the first slide rail 4, moving the support frame 9 laterally. Then, through the extension of multiple sets of first hydraulic cylinders 8, the first bending die 10, in conjunction with the third bending die 13, clamps the sheet material.

Then, the second electric slider 25 slides on the third slide rail 24, and the grooving machine 26 is opened simultaneously, causing the grooving cutter 27 to rotate. The rotating grooving cutter 27 grooves the area of ​​the board that needs to be bent. At the same time, the air inlet of the first exhaust pump 30 is connected to a compressed air source and a low-temperature air source, so that the first exhaust pump 30 discharges compressed gas and low-temperature gas into the jet pipe 28, mixing the two gases. The mixed gas is then sprayed out through the bottom of the jet pipe 28 to cool the grooving cutter 27 and to scatter the debris generated during the grooving process perpendicular to the rear side of the grooving cutter 27. Then, the third slide rail 24 is opened to discharge the air in the filter box 31, creating a negative pressure environment inside the filter box 31. The debris is then sucked into the filter box 31 through the recovery pipe 29. In step 1, multiple sets of filter screens 32 are used to filter debris. After prolonged use, the vibration motor 35 is turned on to vibrate the filter box 31, shaking off the debris from the multiple sets of filter screens 32. Then, the discharge door 33 is opened to discharge the debris from the filter box 31. The debris is collected and then, after slotting, the second hydraulic cylinder 11 extends to move the second bending die 12 upward, cooperating with the first bending die 10 and the third bending die 13 to bend the plate to 80°-85°. Then, the front and rear ends of the plate bending position are blocked by the baffles at the front and rear ends of the second bending die 12, melting the collected debris to form molten steel. The third motor 41 is turned on and driven by the second gear 42 meshing with the rack 40, causing the guide rail 36 to slide on the support frame 9, thus conveying the steel. The height of pipe 37 is adjusted, and multiple sets of thermal induction heaters 38 heat the conveying pipe 37 and the feeding cylinder 39. Multiple sets of flame guns 48 spray flames to heat the bending area of ​​the plate. Then, the molten steel is poured into the feeding cylinder 39 and flows into the conveying pipe 37. The molten steel is discharged through multiple sets of discharge pipes at the bottom of the conveying pipe 37, allowing the molten steel to flow through the perforations of the support frame 9 and the first bending die 10 to the bending area of ​​the plate. After the molten steel cools and solidifies, the gaps in the plate are repaired. Then, the conveying pipe 37 is raised, and then the fifth hydraulic cylinder 46 extends, causing multiple sets of unblocking columns 45 to pass through the multiple perforations of the support frame 9 and the first bending die 10 to clean the residual steel slag in the perforations of the support frame 9 and the first bending die 10.The second hydraulic cylinder 11 then extends further, causing the second bending die 12 to bend the sheet metal to 90°, thereby improving the equipment's usability.
