Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a blackening device for metal product processing. Background Art

[0002] Blackening usually involves immersing a workpiece in a strongly oxidizing chemical solution. For example, in an aqueous solution of sodium hydroxide (600 g / cm3) and sodium nitrite (100 g / cm3) with a boiling temperature of 147 - 152 °C, a beautiful, relatively dense and rust-proof black iron oxide film is formed on the surface after a certain period of time. This process is sometimes also called "bluing" in a mixed way. It is widely used in watches, clock hands, hairsprings, screws, instrument casings and some parts of certain machinery. In machining, bolts are required. To avoid rusting of bolts, bolts need to be put into a blackening solution to form a layer of black iron oxide film.

[0003] Currently, most bolts are blackened manually. First, the bolts are placed in a container filled with blackening solution and soaked for a period of time to form a black iron oxide film, and then the bolts are fished out by hand and put into a collection container. Such operation is rather troublesome and has low work efficiency. Content of the Utility Model

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1 to 5, in the embodiment of the present utility model, a blackening device for metal product processing includes a base 1, a liquid tank 2, a rotating frame 6, a rotating hanging basket 9, a flange ring 12, a cleaning component, a feeding component, and a limiting component; the liquid tank 2 is fixedly connected to the base 1, a liquid groove 3 is arranged in the liquid tank 2, a first support frame 4 is fixedly connected to the base 1, a rotating shaft 5 is rotatably connected in the first support frame 4, the rotating frame 6 is fixedly connected to the rotating shaft 5, multiple groups of mounting frames 7 distributed in a circular pattern are fixedly connected to the rotating frame 6, a fixed shaft 8 is fixedly connected in the mounting frame 7, the rotating hanging basket 9 is rotatably connected to the fixed shaft 8, the flange ring 12 is fixedly connected to the first support frame 4, a motor 10 is fixedly connected to the first support frame 4, and the output shaft of the motor 10 is fixedly connected to the rotating shaft 5; the cleaning component is installed on one side of the base 1 and is used to clean the workpiece after processing; the feeding component is installed on the other side of the base 1 and is used to export and import the workpiece; the limiting component is installed between the rotating hanging basket 9 and the mounting frame 7, and the limiting component cooperates with the flange ring 12 to limit the relative position between the rotating hanging basket 9 and the mounting frame 7. In the present utility model, the blackening liquid is contained in the liquid groove 3, and the workpiece to be processed is transmitted into the rotating hanging basket 9 through the feeding component. Then, the motor 10 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the rotating frame 6 to rotate, the rotating frame 6 drives the rotating hanging basket 9 to rotate through the mounting frame 7. And during the rotation of the rotating frame 6, due to the rotational connection between the rotating hanging basket 9 and the fixed shaft 8, the rotating hanging basket 9 always remains in a vertical state under the action of gravity. When the rotating hanging basket 9 drives the workpiece to rotate and descend into the liquid tank 2, the workpiece is blackened by the blackening liquid in the liquid groove 3. After the blackening processing is completed, the rotating frame 6 drives the rotating hanging basket 9 to rotate to the lower part of the cleaning component, so as to clean the blackening liquid attached to the surface of the workpiece. Then, when the rotating hanging basket 9 rotates to the top, the limiting component limits the position between the fixed cylinder 13 and the positioning cylinder 15 under the action of the flange ring 12, and the rotating hanging basket 9 and the mounting frame 7 cannot rotate relative to each other anymore. Then, as the rotating hanging basket 9 rotates, the rotating hanging basket 9 rotates with the rotating frame 6, from vertical to inclined. Until it rotates above the feeding component, the rotating hanging basket 9 is inclined obliquely downward. At this time, the workpiece in the rotating hanging basket 9 slides down to the discharge end of the feeding component under the action of gravity. Then the rotating hanging basket 9 continues to rotate. When the limiting component loses cooperation with the flange ring 12, the rotating hanging basket 9 rotates to a vertical state under the action of gravity and rotates to the lower part of the discharge end of the feeding component. The feeding component then transmits the unprocessed workpiece into the rotating hanging basket 9.

[0026] In one case of this embodiment, please refer to Figures 1 to 5The cleaning component includes a second support frame 19 fixedly connected to the base 1, a cleaning nozzle 20 is fixedly connected to the second support frame 19, and a drainage groove 21 is fixedly connected to one side of the liquid tank 2. The cleaning component sprays water into the processed rotating hanging basket 9 through the cleaning nozzle 20, thereby flushing the blackening liquid attached to the surface of the workpiece through the water flow, and at the same time, the waste water under flushing is received and discharged through the drainage groove 21.

[0027] In one embodiment of the present invention, see Figures 1 to 5 The material guiding assembly includes a discharging belt 22 and a loading belt 23; the discharging belt 22 and the loading belt 23 are installed on the base 1, and the loading belt 23 is arranged below the discharging belt 22. The material guiding assembly receives and transports the workpieces dumped out from the rotating hanging basket 9 through the discharging belt 22, and then transports the unprocessed workpieces into the rotating hanging basket 9 through the loading belt 23 to realize automatic loading.

[0028] In one embodiment of this invention, see Figures 1 to 5, the limiting component includes a positioning cylinder 15 fixedly connected to the bottom of the rotating hanging basket 9. A fixed cylinder 13 is fixedly connected inside the mounting frame 7. A telescopic insertion rod 14 is slidably connected inside the fixed cylinder 13. The telescopic insertion rod 14 cooperates with the positioning cylinder 15. A connecting plate 16 is fixedly connected to the telescopic insertion rod 14. A spring 17 is arranged between the connecting plate 16 and the mounting frame 7. A guide groove 24 is arranged inside the flange ring 12. A ball 18 is arranged between the connecting plate 16 and the guide groove 24. The limiting component first elastically pushes the connecting plate 16 through the arrangement of the spring 17, so that elastic contact is made between the connecting plate 16 and the flange ring 12. When the ball 18 moves to the concave point of the flange ring 12, the spring 17 pushes the connecting plate 16 to move towards the side away from the mounting frame 7. The connecting plate 16 drives the telescopic insertion rod 14 to be pulled out of the fixed cylinder 13. At this time, the telescopic insertion rod 14 and the positioning cylinder 15 lose their limit. Then, when the rotating hanging basket 9 rotates to the top, the positioning cylinder 15 coincides with the moving cylinder, and the ball 18 moves to the convex point of the flange ring 12. At this time, the connecting plate 16 drives the telescopic insertion rod 14 to insert into the fixed cylinder 13. Finally, the telescopic insertion rod 14 inserts into the positioning cylinder 15. At this time, the fixed cylinder 13 and the positioning cylinder 15 are relatively limited by the telescopic insertion rod 14, and the rotating hanging basket 9 and the mounting frame 7 cannot rotate relative to each other anymore. Then, as the rotating hanging basket 9 rotates, the rotating hanging basket 9 rotates with the rotating frame 6, from vertical to inclined. Until it rotates above the discharge belt 22, the rotating hanging basket 9 is inclined obliquely downward. At this time, the workpiece in the rotating hanging basket 9 slides down to the feeding end of the discharge belt 22 under the action of gravity, so that the processed workpiece is automatically discharged through the discharge belt 22. When the ball 18 moves from the convex point of the flange ring 12 to the concave point of the flange ring 12, the telescopic insertion rod 14 is pushed out of the positioning cylinder 15 again under the elastic push of the spring 17. At this time, the rotating hanging basket 9 and the mounting frame 7 lose their limit again. At this time, the rotating hanging basket 9 rotates to the vertical state under the action of gravity and rotates and moves to below the discharge end of the feeding belt 23.
