Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, and in particular to an angle steel tower opening and closing device. Background Technology

[0002] Angle steel tower is a tower structure made of angle steel, widely used in communications, broadcasting, power and other fields. Angle steel tower is a type of tower assembled by welding, bolting or other methods of angle steel. Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other and forming an angle. It belongs to the category of structural steel. When processing angle steel towers, an opening and closing angle device is required.

[0003] Existing angle opening and closing devices tend to have metal shavings and powders that adhere to the mold surface during processing, causing the angle steel to not fit completely with the mold during opening and closing. This results in dimensional deviations and irregular shapes in the processed angle steel, affecting its appearance quality and assembly accuracy, and thus has certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide an angle steel tower opening and closing device to solve the problems mentioned in the background art.

[0012] As a preferred embodiment of this utility model, the multiple telescopic sleeves are all the same size, and the multiple nozzles are all the same size.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 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. Example

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] An angle steel tower opening and closing device includes a processing table 1. A lower mold 9 is provided at the top of the processing table 1. An installation frame 2 is fixedly installed on the back of the top of the processing table 1. A fixing plate 10 is fixedly installed at the bottom of the front of the installation frame 2. Multiple telescopic sleeves 11 are fixedly connected to the fixing plate 10. A nozzle 12 is fixedly inserted through the bottom of each telescopic sleeve 11. The positions of the multiple nozzles 12 correspond to the positions of the lower mold 9. A pressure plate 15 is provided at the top of the multiple telescopic sleeves 11. The output end of the hydraulic cylinder 3 drives the upper mold 5 to descend. At the same time, the pressure plate 15 is driven to press down the telescopic sleeves 11 through the fixing ring 13 and the connecting rod 14. The air in the telescopic sleeves 11 is sprayed out through the nozzles 12 under the action of extrusion pressure, which acts on the angle steel, the lower mold 9 and the descending upper mold 5 to remove impurities from the mold surface and ensure the mold is clean.

[0023] In this embodiment, a hydraulic cylinder 3 is fixedly installed at the middle of the top of the mounting frame 2. The output end of the hydraulic cylinder 3 passes through the mounting frame 2 and is fixedly connected to a threaded column 4. An upper mold 5 is provided at the top of the lower mold 9. A threaded groove 6 is provided at the middle of the top of the upper mold 5. The outer wall of the threaded column 4 is threadedly connected to the inner wall of the threaded groove 6. The upper mold 5 is threadedly connected to the output end of the hydraulic cylinder 3, which has the characteristics of being detachable and fastened, making it easy to replace the upper mold 5.

[0024] In this embodiment, a slot 7 is provided on one side of the top of the processing table 1. A locking block 8 is engaged with the inner wall of the slot 7. One side of the top of the locking block 8 is fixedly installed with the bottom of the lower mold 9. The slot 7 and the locking block 8 are provided to assist in the installation and disassembly of the lower mold 9.

[0025] In this embodiment, a fixing ring 13 is fixedly installed at the bottom of the output end of the hydraulic cylinder 3. Multiple connecting rods 14 are symmetrically installed on the outer wall of the fixing ring 13. One end of each connecting rod 14 is fixedly installed on the outer wall of the pressure plate 15. The fixing ring 13 and the connecting rods 14 connect the output end of the hydraulic cylinder 3 and the pressure plate 15, so that when the hydraulic cylinder 3 drives the upper mold 5 to rise and fall, it synchronously drives the pressure plate 15 to rise and fall.

[0026] In this embodiment, two symmetrical sliding grooves 16 are provided on the top of the front side of the mounting bracket 2. The inner walls of the two sliding grooves 16 are slidably connected to sliders 17. One end of each slider 17 is fixedly connected to the outer wall of the fixing plate 10. The dimensions of the multiple telescopic sleeves 11 are the same, and the dimensions of the multiple nozzles 12 are the same. The cooperation between the sliding grooves 16 and the sliders 17 plays a role in assisting the pressure plate 15 to rise and fall stably.

[0027] Working principle: During use, the hydraulic cylinder 3 drives the upper mold 5 to descend. The upper mold 5 and the lower mold 9 are used to press the angle steel to process it. When the output end of the hydraulic cylinder 3 descends, it drives the fixing ring 13 and the connecting rod 14 to descend synchronously. This causes the pressure plate 15 to descend and press the telescopic sleeve 11. The air inside the telescopic sleeve 11 is ejected through the nozzle 12 under the action of the extrusion force. This acts on the surface of the lower mold 9 and the angle steel to be processed, cleaning the surface impurities. The output end of the hydraulic cylinder 3 continues to drive the upper mold 5 to descend until the angle steel is pressed by the lower mold 9 and the upper mold 5 to complete the opening and closing angle.
