[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 6 The present invention provides an embodiment of a production device for stamping and forming steel plates for horizontal poles of scaffolding, comprising a workbench 2, bolts 19, and guide plates 21. A lower mold 3 is installed on the upper surface of the workbench 2, and four pillars 1 arranged in a rectangular array are fixed on the lower surface of the workbench 2. The four pillars 1 can support the workbench 2, making the device stable. A fixing plate 12 is fixed at the rear end of the workbench 2, and a bracket 8 is fixed on the upper surface of the fixing plate 12. A groove 9 is opened at the front end of the bracket 8. A guide rod 13 is fixed on the upper surface of the fixing plate 12, and the top end of the guide rod 13 is fixed to the top end of the inner wall of the groove 9.
[0018] A hydraulic cylinder 7 is installed on the upper surface of the support 8. The hydraulic cylinder 7 provides power for the extension and retraction of the hydraulic rod 6, so that the upper mold 5 can move downward as needed to place the stamping material in the lower mold 3. After the upper mold 5 moves downward to fit the lower mold 3, the material is stamped into a scaffold horizontal bar steel plate.
[0019] The hydraulic rod 6 is connected to the inside of the hydraulic cylinder 7 via a piston. The piston slides inside the cylinder, while the hydraulic rod 6 extends out of the cylinder through a seal.
[0020] The hydraulic cylinder 7 is a sealed container filled with hydraulic oil. It typically consists of components such as a cylinder barrel, cylinder head, piston, and piston rod. The piston divides the hydraulic cylinder 7 into two chambers, and the piston rod connects the piston to an external load. The hydraulic rod 6 usually refers to the piston rod, one end of which is connected to the piston, and the other end extends out of the hydraulic cylinder 7 and connects to an external mechanism.
[0021] When the hydraulic pump supplies oil to one chamber of the hydraulic cylinder 7, the pressure in that chamber increases, thereby pushing the piston to move to another chamber. During this process, the hydraulic rod 6 extends or retracts as the piston moves, driving the external load to perform linear motion.
[0022] A hydraulic rod 6 is mounted at the bottom of the hydraulic cylinder 7. A circular hole 14 is opened on the upper surface of the bracket 8. The bottom end of the hydraulic rod 6 mounted on the hydraulic cylinder 7 passes through the circular hole 14. The circular hole 14 facilitates the bottom end of the hydraulic rod 6 mounted on the hydraulic cylinder 7 to pass through the bracket 8. An upper mold 5 is mounted at the bottom end of the hydraulic rod 6. A threaded post 15 is fixed at the bottom end of the hydraulic rod 6. A threaded groove 16 is opened on the upper surface of the upper mold 5. The threaded post 15 extends into the threaded groove 16 and is threaded. The threaded post 15 extends into the threaded groove 16 and is threaded, which facilitates the installation and disassembly of the upper mold 5. A gear 4 is fixed on the outer wall of the upper mold 5. A guide hole 36 is opened on the upper surface of the guide plate 21. The bottom end of the guide rod 13 passes through the guide hole 36. A slot 20 is opened at the front end of the guide plate 21. The upper mold 5 is located at the rear end of the guide plate 21. A connecting plate 17 is fixed at one end, and an insert plate 22 is fixed at the rear end of the connecting plate 17. The insert plate 22 is inserted into the slot 20. Threaded holes 18 are opened on both sides of the guide plate 21, and threaded holes 24 are opened on one side of the insert plate 22. One side of the bolt 19 passes through threaded holes 18 and 24 and is threaded. One side of the bolt 19 passes through nut 23 and is threaded. The insertion of the insert plate 22 into the slot 20 facilitates the connection between the guide plate 21 and the connecting plate 17. At the same time, the guide rod 13 passes through the guide hole 36 and can limit the up and down movement of the upper mold 5. The bolt 19 passes through threaded holes 18 and 24 and is threaded, which facilitates the connection and disassembly of the connecting plate 17 and the guide plate 21, and makes it convenient to replace the upper mold 5.
[0023] A long plate 11 is fixed to one side of the workbench 2. A long groove 32 is opened on the upper surface of the long plate 11. A movable block 34 is inserted into the long groove 32. A motor 2 30 is fixed to one side of the long plate 11. A screw 33 is fixed to one side of the transmission shaft of the motor 2 30. One side of the screw 33 passes through the movable block 34 and is threaded. A threaded hole 35 is opened on one side of the movable block 34. A round hole 31 is opened on one side of the long plate 11. One side of the transmission shaft of the motor 2 30 extends into the round hole 31. A screw 33 is fixed to one side of the transmission shaft of the motor 2 30. One side of the screw 33 passes through the threaded hole 35 and is threaded. The screw 33 is fixed by the transmission shaft of the motor 2 30, which provides power for the rotation of the screw 33, so that the gear 2 10 can be moved as needed, which facilitates the rotation, installation and disassembly of the upper mold 5. A bracket 25 is fixed to the upper surface of the movable block 34. Motors 26 and 30 are servo motors. These servo motors should be able to rotate in both directions as needed. To achieve this, AC servo motors should be selected, equipped with high-precision encoders and bidirectional control drivers. The motor parameters must meet the load requirements and possess necessary protection functions. Motor 26's ability to rotate in both directions allows gears 10 and 4 to rotate in both directions as needed, facilitating the rotational installation and disassembly of the upper mold 5 without manual rotation, saving time and labor. The upper surface of bracket 25 is rotatably connected to rotating rod 27. The front end of bracket 25 has a groove 29, and the top of the inner wall of groove 29 has a round hole 28. Motor 1 26 is fixed to the top of the inner wall of groove 29. The top of the transmission shaft of motor 1 26 extends into the round hole 28. The top of the transmission shaft of motor 1 26 is fixed to rotating rod 27. The rotating rod 27 is fixed by the transmission shaft of motor 1 26, which provides power for the rotation of rotating rod 27 and gear 2 10, so that gear 1 4 and upper mold 5 can rotate as needed, which facilitates the installation and disassembly of upper mold 5. Gear 2 10 is fixed to the top of rotating rod 27, and gear 1 4 and gear 2 10 are meshed together.
[0024] When stamping the steel plates of the scaffold horizontal poles, it is necessary to change the appropriate upper die 5 according to the different steel plates. To change the upper die 5, rotate bolt 19 to move it out of threaded hole 18 and threaded hole 24, then move insert plate 22 out of slot 20. Start motor 20 to rotate screw 33, causing moving block 34 and gear 20 to move, engaging gear 20 with gear 14. Then start motor 26 to rotate rotating rod 27 and gear 20, simultaneously rotating gear 14 and upper die 5. Threaded column 15 moves out of threaded groove 16, allowing the upper die 5 to be disassembled and replaced. This achieves the effect of changing the upper die 5 according to the needs of the scaffold horizontal pole steel plates, reducing limitations on the upper die 5, facilitating its replacement, and eliminating the need for manual rotation of the upper die 5 for installation and disassembly.
