[0026] Example

[0027] like Figures 1 to 4 As shown, a bolt production pickling device comprises a pickling tank 1, a track 2, a cleaning mechanism 3 and a conveying mechanism 4. A partition 11 is provided in the middle of the pickling tank 1 to separate it into a pickling area 12 and a water washing area 13. The conveying mechanism 4 is located on one side of the water washing area 13. The upper end of the partition 11 and the upper end of the water washing area 13 close to the conveying mechanism 4 are both provided with a slot 111 for the cleaning mechanism 3 to pass through. The track 2 is erected above the pickling tank 1 and the conveying mechanism 4, and the cleaning mechanism 3 is slidably arranged on the track 2. The utility model utilizes the cleaning mechanism 3 to pickle and flush the bolts inside in the pickling area 12 and the water washing area 13 in turn, avoiding the need for manual intervention in salvage that may endanger personal safety. The utility model is fully automated and uses the conveying mechanism 4 to transport the bolts that have been pickled and flushed with water to the next process, thereby improving work efficiency.

[0028] In this embodiment, refer to Figure 1-Figure 3The cleaning mechanism 3 includes a cleaning basket 31, a driving trolley 32 and a hydraulic cylinder 33. The driving trolley 32 is slidably connected to the track 2. A hydraulic cylinder 33 is provided at the lower end of the driving trolley 32. The telescopic end of the hydraulic cylinder 33 is hinged to the cleaning basket 31. The cleaning basket 31 can be driven by the driving trolley 32 to move back and forth in the pickling area 12 and the water washing area 13, thereby driving the bolts in the cleaning basket 31 to flush back and forth to remove the oxide scale and rust on the surface thereof, thereby improving its pickling efficiency and cleaning efficiency. At the same time, the hydraulic cylinder 33 is used to drive the cleaning basket 31 to move up and down, so that the cleaning basket 31 can pass through the slot 111, and the operation of the cleaning basket 31 between the pickling area 12, the water washing area 13 and the conveying mechanism 4 is convenient.

[0029] Specifically, the driving trolley 32 includes a U-shaped frame 321 and two sets of sliding wheel groups 322 correspondingly slidably connected to the track 2. The U-shaped frame 321 is buckled upward on the track 2, and the two sets of sliding wheel groups 322 are respectively connected to the inner walls on both sides of the U-shaped frame 321. A hydraulic cylinder 33 is provided at the lower end of the U-shaped frame 321; the two sliding wheels can be specifically set as a set of sliding wheel groups 322, and the number of sliding wheels can be set according to actual conditions.

[0030] In this embodiment, two rails 2 are provided, and four driving trolleys 32 are provided, and a driving trolley 32 is provided at the front and rear of each rail 2. Specifically, a driving trolley 32 located at the front end is provided with a driving motor 323 connected to one set of sliding wheel sets 322; the driving motor 323 can be used as a power source for the driving trolley 32.

[0031] In this embodiment, refer to Figure 2 and Figure 4 The bottom of the cleaning basket 31 is rotatably connected with two bottom nets 311, and the bottom net 311 and the inner wall of the cleaning basket 31 on one side adjacent to it are hinged with an electric telescopic rod 5. When the electric telescopic rod 5 is driven to extend or retract, the bottom net 311 is opened or closed; during the pickling and water washing process, the bottom net 311 is in a closed state to prevent the bolts in the cleaning basket 31 from falling. After the pickling and water washing are completed, the cleaning basket 31 slides onto the conveying mechanism 4, and the electric telescopic rod 5 can be used to open the bottom net 311 to complete the transportation of the bolts.

[0032] In this embodiment, a limiting plate 6 is provided in the middle of the lower end, and the end of the bottom net 311 away from the rotational connection with the washing basket 31 abuts against the limiting plate 6; the limiting plate 6 serves to close the two bottom nets 311 and limit their upward flipping.

[0033] The device is applicable to bolts but not limited thereto, and can also be applied to fasteners such as screws that require pickling operations.

[0034] The working principle of this utility model:

[0035] The utility model provides a bolt production pickling device. When in use, a cleaning basket 31 is placed in the bolts to be pickled, and the cleaning basket 31 is lowered into the pickling liquid in the pickling area 12 by a hydraulic cylinder 33. The cleaning basket 31 is driven by a driving trolley 32 to move back and forth in the pickling area 12 to remove the oxide scale and rust on the surface thereof.

[0036] After the pickling is completed, the hydraulic cylinder 33 contracts and drives the cleaning basket 31 to move upward and move the trolley 32 to the water washing area 13 to move back and forth for flushing; then the cleaning basket 31 is moved upward, and after the bolts are naturally dried, the cleaning basket 31 is moved to the conveying mechanism 4 by the driving trolley 32 to open the bottom net 311 to complete the unloading. The utility model has the technical characteristics of using the cleaning mechanism 3 to perform pickling and water flushing operations on the bolts inside in the pickling area 12 and the water washing area 13 in turn, avoiding the need for manual intervention in salvage that may endanger personal safety, and the whole process is automatically operated and the bolts that have been pickled and flushed with water are transported to the next process with the help of the conveying mechanism 4, thereby improving work efficiency.
