Description

Technical Field

[0001] This utility model relates to the field of steam turbine processing, and in particular to a metal bending device for steam turbine processing. Background Technology

[0002] A search of Chinese patents revealed publication number CN221715353U, which discloses a metal bending device for steam turbine processing. This device improves bending efficiency and reduces operational steps. It includes a mounting base, an operating table, a bending die, a cylinder, a bending die, a storage box, a feeding mechanism, and a clamping mechanism. The operating table is mounted on top of the mounting base. The bending die is mounted on the operating table, which has a material discharge groove. The cylinder is mounted on the operating table, and the bending die is mounted at the cylinder's output end. The bending die and the bending die are installed correspondingly. The storage box is mounted on the operating table, with a discharge port on one side. The clamping mechanism is mounted on the mounting base, and the feeding mechanism is mounted on the operating table and correspondingly installed with the storage box.

[0003] Existing bending equipment is inconvenient for mold replacement. Generally, the molds on bending equipment are fixed with multiple bolts, requiring tools for disassembly and reassembly during replacement. This process is cumbersome, increases workload, reduces replacement efficiency, and is inconvenient to use. Furthermore, it lacks positioning functionality. Typically, when bending metal workpieces, a marker is used to mark the bending position on the workpiece surface before placing it on the bottom mold of the bending equipment, ensuring the top mold is flush with the mark, and then bending. This operation is cumbersome and makes it difficult to guarantee the accuracy of the bending position, further increasing workload, reducing bending efficiency, and making it inconvenient to use. To address these problems, we propose a metal parts bending device for steam turbine processing. Utility Model Content

[0015] The present invention is further configured such that: both ends of the slide rod are bolted with sliders, the surface of the sliders is slidably connected with a groove, and the groove is formed on the inner wall of the operating table.

[0016] By adopting the above technical solution, the slider and groove are set to prevent the slider from deviating and improve stability.

[0017] The present invention is further configured such that the surface of the operating table is printed with scale lines.

A lifting mechanism 3 is installed inside the fixed frame 2. Fixed seats 4 are bolted to the bottom of the lifting mechanism 3 and the top of the operating table 1, respectively. A top mold 5 and a bottom mold 6 are slidably connected to the inner wall of the fixed seat 4. A fixing clip 7 is provided through the inner wall of the top mold 5 and the bottom mold 6, and the fixing clip 7 is also provided through the inner wall of the fixed seat 4. A locking rod 8 is slidably connected to the inner wall of the fixed seat 4. A spring 9 is provided between one end of the locking rod 8. A locking hole 10 is opened on the surface of the fixing clip 7, and the locking hole 10 is locked with the locking rod 8. A toggle block 11 is bolted to the surface of the locking rod 8. By moving the toggle block 11, the locking rod 8 moves, causing the locking rod 8 to disengage from the locking hole 10, allowing the fixing clip 7 to be removed and the mold to be removed for replacement. This method facilitates mold replacement, reduces workload, and improves replacement efficiency.

[0032] refer to Figure 2 The lifting mechanism 3 includes a hydraulic rod 19, which is bolted to the top of the fixed frame 2. The output end of the hydraulic rod 19 is bolted to a lifting plate 20, which is slidably connected to the inner wall of the fixed frame 2. The bottom of the lifting plate 20 is bolted to the top fixed seat 4. By setting the lifting mechanism 3, it is convenient to bend the workpiece.

[0033] refer to Figure 4 One end of the locking rod 8 is wedge-shaped, which facilitates the fixing of the locking clip 7.

[0034] refer to Figure 4 The surface of the toggle block 11 is provided with anti-slip texture 21. By setting the anti-slip texture 21, the hand slips and the operation is facilitated.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 and Figure 3A bidirectional lead screw 12 is rotatably sleeved between the inner walls of the operating table 1. A motor 13 is bolted to the surface of the operating table 1, and the output end of the motor 13 is connected to one end of the bidirectional lead screw 12 via a coupling. A sliding block 14 is threaded onto the surface of the bidirectional lead screw 12. A support rod 15 is hinged to the surface of the sliding block 14. A slide rod 16 is hinged to the other end of the support rod 15. A fixing rod 17 is bolted to the top of the slide rod 16, and a positioning plate 18 is bolted to the top of the fixing rod 17. By setting the positioning plate 18, the metal workpiece is positioned, ensuring the bending accuracy, reducing the workload, and improving work efficiency. The rotation of the motor 13 drives the bidirectional lead screw 12 to move the sliding block 14. The movement of the sliding block 14 causes the support rod 15 to move the slide rod 16. The movement of the slide plate causes the positioning plate 18 to move, which can adjust the position of the positioning plate 18, thereby facilitating the adjustment of the bending position and improving practicality.

[0037] refer to Figure 3 Both ends of the slide rod 16 are bolted with sliders 22. The surface of the sliders 22 is slidably connected with grooves 23, and the grooves 23 are opened on the inner wall of the operating table 1. By setting sliders 22 and grooves 23, the slide rod 16 is prevented from deviating and the stability is improved.

[0039] refer to Figure 1 and Figure 2 A pad 25 is bolted to the bottom of the operating table 1. The stability of the device is improved by setting the pad 25.

[0040] Brief description of the operation: The rotation of motor 13 drives the rotation of the double-acting lead screw 12, which in turn drives the sliding block 14 to move. The movement of the sliding block 14 drives the support rod 15 to move, which in turn drives the sliding rod 16 to move. The movement of the sliding rod 16 drives the fixed rod 17 to move, which in turn drives the positioning plate 18 to move. The positioning plate 18 is moved to the required position. Then, the metal workpiece is placed on the bottom mold 6 and pressed against the positioning plate 18. Then, the hydraulic rod 19 is opened, and its movement drives the lifting plate 20 to move. The lifting plate 20 moves, causing the top mold 5 to move. The moving top mold 5 bends the metal workpiece, thus achieving the purpose of positioning. The moving toggle block 11 moves, causing the locking rod 8 to move. The moving locking rod 8 disengages from the locking hole 10, removing the fixing clip 7. The bottom mold 6 or the top mold 5 is then removed, and the new top mold 5 or bottom mold 6 is installed in the fixing seat 4. The fixing pin is inserted, and the locking rod 8 engages with the locking hole 10 under the action of the spring 9, fixing the fixing clip 7 and completing the fixing, thereby facilitating mold replacement.
