A telescopic rod is fixedly connected to the output end of the cylinder. This utility model has the following advantages and effects: driving the telescopic rod to retract causes the buffer frame to descend. During descent, one side of the buffer frame generates friction with the pusher bar for buffering. The machine descends to a suitable height according to the thickness of the sheet metal.

Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a high-efficiency hydraulic bending machine. Background Technology

[0002] Metal sheets have a wide range of uses in daily life. When metal sheets are used in different occasions, they need to be processed into specific shapes. Bending is a common processing method. When bending metal sheets, metal sheet bending machines are often used for bending processing.

[0003] In the prior art, Chinese Patent Publication No. CN219211163U discloses a metal sheet bending machine with a feeding structure, which includes a sheet bending machine body and a distance adjustment component. The distance adjustment component includes a bracket, with two fixed blocks fixedly connected to the upper end of the bracket. A bidirectional lead screw is movably connected to the inner side of the two fixed blocks and towards the rear. A crossbar is fixedly connected between the two fixed blocks. Two threaded sleeves are threadedly connected to the wall of the bidirectional lead screw. A fixed plate is fixedly connected to the outer side of the threaded sleeves. First rotating shafts are movably connected to both sides of the fixed plate. Circular sleeves are fixedly connected to the adjacent sides of the two first rotating shafts. Vertical rods are movably connected to the upper and lower ends of the circular sleeves. This application relates to a metal sheet bending machine with a feeding structure, which can adjust and fix the distance for metal sheets of different sizes. During feeding, the metal sheet is fixed to prevent tilting or deflection, which could cause the bending point of the metal sheet to shift and affect the processing accuracy.

[0004] However, in actual use, this utility model requires operations such as rotating the threaded rod to fix the plate, which involves many manual steps. This makes it time-consuming to place the plate and affects processing efficiency, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency hydraulic bending machine that allows for the simple placement of sheet metal in a fixed position without additional operation, thereby saving operation time and improving processing efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency hydraulic bending machine, including a bending machine body, a feeding platform fixedly connected to the inner wall of the bending machine body, a pusher bar fixedly connected to the top of the feeding platform, an installation groove opened on the top of the pusher bar, a cylinder fixedly connected to the inner wall of the installation groove, a telescopic rod fixedly connected to the output end of the cylinder, an installation plate fixedly connected to the top of the telescopic rod, a buffer frame movably installed on the top of the installation plate, a fixed frame fixedly connected to the bottom of the buffer frame, and a pressure roller provided on the inner wall of the fixed frame.

[0007] By adopting the above technical solution, the staff can install the buffer frame and the mounting plate accordingly. When feeding, the board is placed directly on the top of the feeding table, with one end of the board abutting the side of the pusher bar. At the same time, the top of the board corresponds to the bottom of the pressure roller. Then, the cylinder is activated, driving the telescopic rod to retract and causing the buffer frame to descend. During descent, one side of the buffer frame generates friction with the pusher bar to buffer the board. The board descends to a suitable height according to its thickness. After the pressure roller descends, a small gap is left between it and the board, which does not lock or fix the board and restrict its displacement. The movement of the pusher bar pushes the board to feed it. When placing the board, it is only necessary to place it in the fixed position without any additional operation, thereby saving operation time and improving processing efficiency.

[0008] A further feature of this invention is that an anti-slip sleeve is fixedly connected to the outer surface of the pressure roller, and the anti-slip sleeve is made of rubber.

[0009] By adopting the above technical solution, the anti-slip sleeve can avoid damaging the surface of the board.

[0010] A further feature of this invention is that the top of the mounting plate has a threaded hole, and the top of the buffer frame is threaded with a bolt.

[0011] By adopting the above technical solution, the mounting plate and buffer frame are positioned and installed, and the bolts are aligned with the threaded holes.

[0012] A further feature of this invention is that the bottom of the bolt is threaded with a nut, and the number of bolts is four.

[0013] By adopting the above technical solution, the bottom of the bolt is fixed by the nut, and the pressure roller can be disassembled.

[0014] A further feature of this invention is that an extension platform is fixedly connected to one end of the feeding platform, and a second cylinder is fixedly connected to the top of the extension platform.

[0015] By adopting the above technical solution, the extension table facilitates the fixing of the second cylinder, and the second cylinder is activated when feeding.

[0016] A further feature of this invention is that a second telescopic rod is fixedly connected to the output end of the second cylinder, and a drive plate is fixedly connected to one end of the second telescopic rod.

[0017] By adopting the above technical solution, after the second cylinder is started, it drives the extension of the second telescopic rod, which in turn pushes the drive plate to move.

[0018] A further feature of this invention is that one side of the drive plate is fixedly connected to the pusher bar, and the number of drive plates is two.

[0019] By adopting the above technical solution, the two ends of the push bar are pushed by the drive plate, thereby feeding the plate.

[0020] A further feature of this invention is that a guide groove is provided on the top of the feeding platform, and a guide block is fixedly connected to the bottom of the pusher bar.

[0021] By adopting the above technical solution, the guide groove facilitates the directional movement of the pusher bar, and the movement is smooth.

[0022] A further feature of this invention is that a spacer strip is fixedly connected to the inner wall of the bending machine body, and a hydraulic cylinder is fixedly connected to the top of the bending machine body.

[0023] By adopting the above technical solution, a gap is left between the spacer strip and the feeding table, which facilitates the bending of the sheet metal.

[0024] A further feature of this invention is that a hydraulic telescopic rod is fixedly connected to the output end of the hydraulic cylinder, and a bending knife is fixedly connected to the bottom of the hydraulic telescopic rod.

[0025] By adopting the above technical solution, the bending blade presses down to compress and bend the sheet metal.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the coordinated arrangement of the bending machine body, feeding table, pusher bar, mounting groove, cylinder, telescopic rod, mounting plate, buffer frame, fixed frame, and pressure roller, enables the device to directly place the sheet metal on the top of the feeding table during feeding, with one end of the sheet metal abutting the side of the pusher bar, and the top corresponding to the bottom of the pressure roller. Then, the cylinder is activated, driving the telescopic rod to retract, causing the buffer frame to descend. During descent, one side of the buffer frame generates friction with the pusher bar for cushioning. The sheet metal descends to a suitable height according to its thickness. After the pressure roller descends, a small gap remains between it and the sheet metal, preventing the sheet metal from being locked or fixed and restricting its displacement. The movement of the pusher bar propels the sheet metal for feeding. When placing the sheet metal, simply place it in the fixed position; no additional operation is required, thus saving operation time and improving processing efficiency.

[0036] A high-efficiency hydraulic bending machine includes the following embodiments:

[0037] Example 1:

[0038] Reference Figure 1-4 A feeding platform 2 is fixedly connected to the inner wall of the bending machine body 1. A pusher bar 3 is fixedly connected to the top of the feeding platform 2. An installation groove 4 is opened on the top of the pusher bar 3. A cylinder 5 is fixedly connected to the inner wall of the installation groove 4. A telescopic rod 6 is fixedly connected to the output end of the cylinder 5. An installation plate 7 is fixedly connected to the top of the telescopic rod 6. A buffer frame 8 is movably installed on the top of the installation plate 7. A fixed frame 9 is fixedly connected to the bottom of the buffer frame 8. A pressure roller 10 is provided on the inner wall of the fixed frame 9.

[0039] Specifically, when using the equipment, the staff installs the buffer frame 8 and the mounting plate 7 accordingly. When feeding, the plate is placed directly on the top of the feeding table 2, with one end of the plate abutting the side of the pusher bar 3. At the same time, the top corresponds to the bottom of the pressure roller 10. Then, the cylinder 5 is activated, driving the telescopic rod 6 to retract, which drives the buffer frame 8 to descend. When descending, one side of the buffer frame 8 generates friction buffer with the pusher bar 3. The plate descends to a suitable height according to the thickness of the plate. After the pressure roller 10 descends, there is a small gap between it and the plate, which does not lock the plate and restrict the displacement of the plate. The movement of the pusher bar 3 pushes the plate to feed. When placing the plate, it is only necessary to place the plate in a fixed position without any additional operation, thereby saving operation time and improving processing efficiency.

[0040] Example 2:

[0041] Reference Figure 1-4 The outer surface of the pressure roller 10 is fixedly connected with an anti-slip sleeve 11, which is made of rubber. The top of the mounting plate 7 is provided with a threaded hole 12. The top of the buffer frame 8 is threadedly connected with a bolt 13, and the bottom of the bolt 13 is threadedly connected with a nut 14. There are four bolts 13. One end of the feeding table 2 is fixedly connected with an extension table 15. The top of the extension table 15 is fixedly connected with a second cylinder 16. The output end of the second cylinder 16 is fixedly connected with a second telescopic rod 17. One end of the second telescopic rod 17 is fixedly connected with a drive plate 18. One side of the drive plate 18 is fixedly connected with a pusher bar 3. There are two drive plates 18. The top of the feeding table 2 is provided with a guide groove 19. The bottom of the pusher bar 3 is fixedly connected with a guide block. The inner wall of the bending machine body 1 is fixedly connected with a spacer bar 20. The top of the bending machine body 1 is fixedly connected with a hydraulic cylinder 21. The output end of the hydraulic cylinder 21 is fixedly connected with a hydraulic telescopic rod 22. The bottom of the hydraulic telescopic rod 22 is fixedly connected with a bending knife 23.

[0042] Specifically, the anti-slip sleeve 11 can prevent damage to the surface of the board. The mounting plate 7 and the buffer frame 8 are positioned and installed. The bolt 13 is aligned with the threaded hole 12. The bottom of the bolt 13 is fixed by the nut 14. The pressure roller 10 can be disassembled. The extension table 15 facilitates the fixing of the second cylinder 16. When feeding, the second cylinder 16 is started. After the second cylinder 16 is started, it drives the extension of the second telescopic rod 17, which pushes the drive plate 18 to move. The two ends of the pusher bar 3 are pushed by the drive plate 18, thereby feeding the board. The guide groove 19 facilitates the directional movement of the pusher bar 3 and the movement is smooth. There is a gap between the spacer bar 20 and the feeding table 2 to facilitate the bending of the board. The bending knife 23 presses down to compress and bend the board.

[0043] In this invention, the sheet material is placed directly on the top of the feeding table 2 during feeding, with one end of the sheet material abutting the side of the pusher bar 3 and the top corresponding to the bottom of the pressure roller 10. Then, the cylinder 5 is activated, driving the telescopic rod 6 to retract, which in turn drives the buffer frame 8 to descend. During descent, one side of the buffer frame 8 generates friction with the pusher bar 3 for buffering. The material descends to a suitable height according to its thickness. After the pressure roller 10 descends, a small gap remains between it and the sheet material, preventing the material from being locked and fixed, thus limiting the displacement of the material. The movement of the pusher bar 3 pushes the sheet material for feeding. When placing the sheet material, it is only necessary to place it in a fixed position without any additional operation, thereby saving operation time and improving processing efficiency. The anti-slip sleeve 11 can prevent damage to the surface of the sheet material. The mounting plate 7 and the buffer frame 8 are positioned and installed, with the bolt 13 corresponding to the threaded hole 12. The bottom of the bolt 13 is fixed by the nut 14. The pressure roller 10 can be disassembled. After the second cylinder 16 is activated, it drives the extension of the second telescopic rod 17, pushing the drive plate 18 to move. The guide groove 19 facilitates the directional movement of the pusher bar 3, ensuring smooth movement.
