Technical Field

[0001] The utility model relates to the technical field of wire material processing, in particular to a phosphating device for expansion bolt wire materials. Background Art

[0002] The wire used in expansion bolt production requires phosphating. Phosphating involves a chemical and electrochemical reaction that forms a phosphate conversion coating, known as a phosphate film.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] See also Figures 1 to 4 The embodiment of the present application provides a phosphating device for expansion bolt wire, including a phosphating tank 1 and a sling 2, the sling 2 including a fixed frame 21, a movable frame 22, and a vibration mechanism 23, the phosphating tank 1 can support the fixed frame 21, the movable frame 22 includes a movable crossbeam 221, a movable vertical arm 222, and a supporting arm 223, the lower end of the movable crossbeam 221 is fixed with a movable vertical arm 222, the lower end of the movable vertical arm 222 is fixed with a supporting arm 223, and the supporting arm 223 is used to mount the wire; the vibration mechanism 23 includes a rotating power source 231, a rotating shaft 232, an eccentric wheel 233, a roller assembly 234, and a guide rod 2 35. Guide sleeves 236. Two guide rods 235 and two guide sleeves 236 are provided. The rotary power source 231 and guide sleeve 236 are both fixedly connected to the fixed frame 21. The rotating shaft 232 is rotatably connected to the fixed frame 21. Roller assemblies 234 are mounted on both sides of the lower end of the movable crossbeam 221. Eccentric wheels 233 are fixedly mounted on the rotating shaft 232. The eccentric wheels 233 correspond to the roller assemblies 234 one-to-one and are in rolling connection with the wheel bodies of the roller assemblies 234. The guide rods 235 are fixedly mounted on the movable crossbeam 221 and are slidably connected to the guide sleeves 236. The rotary power source 231 drives the rotating shaft 232 to rotate, thereby driving the eccentric wheels 233 to rotate. Under the guidance of the guide rods 235 and guide sleeves 236, the eccentric wheels 233 drive the roller assemblies 234, the movable frame 22, and the wire rods to move up and down, ensuring that the wire rods are fully exposed to the acid solution and improving the phosphating treatment effect.

[0022] The fixed frame 21 includes a fixed beam 211, a fixed arm 212, and a fixed base 213. The fixed beam 211 is located directly above the movable beam 221. The fixed arms 212 are fixed at both ends of the fixed beam 211, and the fixed base 213 is fixed at the lower end of the fixed arms 212. The guide sleeve 236 is fixed to the fixed beam 211.

[0023] To rotatably mount the rotating shaft 232 on the fixed frame 21, a first bearing 214 is embedded in the fixed vertical arm 212, and the rotating shaft 232 is rotatably connected to the first bearing 214. The first bearing 214 is embedded in both fixed vertical arms 212. The first bearing 214 can be a deep groove ball bearing to stably support the rotation of the rotating shaft 232.

[0024] To further enhance the support stability of the rotating shaft 232, a bearing seat 215 is fixed to the fixed base 213. A second bearing 216 is mounted within the bearing seat 215. The rotating shaft 232 is rotatably connected to the second bearing 216. The bearing seats 215 are fixed to the two fixed bases 213. The second bearing 216 uses a deep groove ball bearing to stably support the rotation of the rotating shaft 232. The first bearing 214 and the second bearing 216 are located on either side of the eccentric 233, providing stable support for the rotating shaft 232, allowing the eccentric 233 to stably drive the roller assembly 234 up and down.

[0025] To facilitate positioning of the sling 2 during phosphating, limit its significant movement, and prevent it from tipping over, a retaining hole 217 is provided on the fixed base 213. A retaining seat 11 corresponding to the fixed base 213 is fixed to the phosphating tank 1. A retaining post 12 is fixed to the retaining seat 11 and engages with the retaining hole 217. The retaining post 12 is slightly smaller than the retaining hole 217, facilitating its insertion. The retaining post 12 and retaining hole 217 restrict movement of the fixed base 213.

[0026] For the convenience of moving the sling 2, a lifting lug 218 is fixed on the upper end of the fixed crossbeam 211, and the lifting lug 218 is set to two. The lifting lug 218 is connected by the hook of the lifting equipment to drive the sling 2 to move.

[0027] To facilitate the installation of the rotary power source 231, a mounting base is provided on the fixed crossbeam 211. The rotary power source 231 is fixedly mounted on the mounting base. The rotary power source 231 uses a reduction motor, or alternatively, a reduction pneumatic motor or a low-speed hydraulic motor. A driving sprocket 237 is mounted on the output end of the rotary power source 231, and a driven sprocket 238 is mounted on the rotating shaft 232. The driving sprocket 237 and the driven sprocket 238 are connected by a chain 239. The rotary power source 231 drives the driving sprocket 237 to rotate. The driving sprocket 237 drives the driven sprocket 238 and the rotating shaft 232 to rotate via the chain 239. The rotation of the driving sprocket 237 drives the eccentric wheel 233 to rotate. As the eccentric wheel 233 rotates, it continuously lifts the roller assembly 234, causing the roller assembly 234 to vibrate up and down. This in turn drives the movable frame 22 and the wire rod to move up and down, ensuring that the wire rod is fully exposed to the acid solution and improving the phosphating treatment effect.

[0028] To prevent the movable arm 222 from interfering with the shaft 232 when the movable frame 22 moves up and down, an opening 224 is provided on the movable arm 222 for the shaft 232 to move. When the movable arm 222 moves up and down, the shaft 232 is always located in the opening 224 and does not contact or interfere with the movable arm 222.

[0029] In order to prevent the wire from escaping from the support arm 223 in the phosphating tank 1, a fixed limit block 225 is provided at one end of the support arm 223 away from the movable arm 222. The limit block 225 can block the wire on the support arm 223 and prevent the wire from sliding out of the support arm 223.

[0030] The working principle of this embodiment is as follows:

[0031] The wire to be phosphated is mounted on the support arm 223, connected to the lifting lug 218 through external lifting equipment, and the sling 2 is hoisted to the phosphating tank 1. The fixed base 213 is moved to the clamping seat 11, and the clamping column 12 is clamped into the clamping hole 217 to achieve the positioning of the fixed frame 21. At this time, the wire is immersed in the acid solution of the phosphating tank 1;

[0032] Subsequently, the rotary power source 231 is started, and the rotary power source 231 drives the rotating shaft 232 and the eccentric wheel 233 to rotate. The eccentric wheel 233 drives the roller assembly 234 to vibrate up and down, thereby driving the movable frame 22 and the wire to move up and down, so that the wire is fully in contact with the acid solution, thereby improving the phosphating treatment effect.
