Description

Technical Field

[0001] This utility model relates to the field of metal workpiece processing technology, and in particular to a rust removal device for metal workpieces. Background Technology

[0002] Common industrial methods for removing rust include pickling and high-pressure water jetting. Pickling involves immersing the workpiece in a pickling solution to remove oxides from its surface. After pickling, the workpiece becomes easier to process. Typically, metal workpieces are directly immersed in the pickling tank. Since the workpiece is stationary relative to the pickling solution, this method requires a longer reaction time between the pickling solution and the oxides, resulting in a slow pickling speed and low efficiency. Therefore, we propose a rust removal device for metal workpieces. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a rust removal device for metal workpieces, thereby resolving the issues raised in the background section.

[0004] This utility model discloses a rust removal device for metal workpieces, including a base on which a rust removal pool is placed. Supports are installed on both sides of the base. An electric push rod is provided at the top of the support, and a basket is provided at the output end of the electric push rod. A motor is provided at the bottom of the base, and a driving bevel gear is provided at the output end of the motor. The driving bevel gear is laterally meshed with a driven bevel gear, which is fixedly sleeved on a rotating rod. A stirring blade is provided at the upper end of the rotating rod, and the stirring blade is rotatably disposed in the rust removal pool.

[0005] In the above scheme, positioning holes are provided on the sides of the base and the bracket.

[0006] In the above scheme, the positioning hole has a fixing bolt on its internal thread, and the fixing bolt has a nut on its external thread.

[0007] In the above scheme, a bearing is fixedly sleeved on the outside of the bottom of the rotating rod, and the bottom of the rotating rod is movably mounted on the base through the bearing.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-4As shown, this utility model is a rust removal device for metal workpieces, including a base 1, on which a rust removal pool 11 is placed. Supports 12 are installed on both sides of the base 1. An electric push rod 14 is provided at the top of each support 12. A placement basket 15 is provided at the output end of the electric push rod 14. The workpiece to be rusted is placed in the placement basket 15. A pickling solution is injected into the rust removal pool 11. By turning on the electric push rod 14, the lower placement basket 15 is pushed and immersed into the rust removal pool 11. Filter holes 17 are provided on the placement basket 15. A protrusion 16 is fixed at the upper end of the placement basket 15. The pickling solution in the rust removal pool 11 is circulated through... The filter hole 17 enters the workpiece surface and reacts with the oxides on the workpiece surface to remove rust. The protrusion 16 can be used to lift the workpiece, increasing the contact area between the bottom of the metal workpiece and the pickling solution, making the rust removal surface larger and enhancing the pickling effect. After the rust removal is completed, the metal workpiece can be easily removed from the rust removal tank 11 by turning on the electric push rod 14 switch. The filter hole 17 is designed to facilitate the pickling solution to enter the placement basket 15 for rust removal reaction, and to filter the waste residue generated during rust removal into the placement basket 15 for centralized treatment, preventing the waste residue from settling at the bottom of the rust removal tank 11 and affecting the stirring blade 25 at the bottom.

[0020] A motor 2 is installed at the bottom of the base 1. A driving bevel gear 21 is installed at the output end of the motor 2. The driving bevel gear 21 is laterally meshed with a driven bevel gear 22. The driven bevel gear 22 is fixedly mounted on a rotating rod 23. A stirring blade 25 is installed at the upper end of the rotating rod 23. The stirring blade 25 is rotatably positioned within the rust removal tank 11. When rust removal of the metal workpiece begins, the motor 2 is switched on, and the driving bevel gear 21 at the output end of the motor 2 begins to rotate. The rotation of the driving bevel gear 21 drives the laterally meshed driven bevel gear 22. 2. The driven bevel gear 22 rotates, which drives the rotating rod 23. The bottom of the rotating rod 23 is fixedly sleeved with a bearing. The bottom of the rotating rod 23 is movably mounted on the base 1 through the bearing. The rotating rod 23 can be driven to rotate by the driven bevel gear 22. The rotation of the rotating rod 23 can drive the stirring blade 25 fixed at the top to start rotating. The stirring blade 25 causes the pickling solution to flow rapidly. When the pickling solution starts to flow, it will wash the metal workpiece, thereby accelerating the separation speed of rust and metal workpiece, and thus improving the rust removal efficiency.

[0021] In the above scheme, positioning holes 13 are opened on the sides of the base 1 and the bracket 12. The positioning holes 13 are threaded with fixing bolts 3, and the outer surface of the fixing bolts 3 is threaded with nuts 31. When it is necessary to inspect the electric push rod 14 and the placement basket 15 on the bracket 12, the fixing bolts 3 and nuts 31 can be unscrewed from the inside of the positioning holes 13 to release the fixing of the bracket 12, which facilitates the inspection and maintenance of the equipment on the bracket 12.

[0022] In the above scheme, a waterproof sealing bearing 24 is embedded in the bottom cavity of the rust removal pool 11, and the rotating rod 23 is movably set in the rust removal pool 11 through the waterproof sealing bearing 24. The waterproof sealing bearing 24 can ensure that the rust removal liquid in the rust removal pool 11 does not leak from the rotating end of the rotating rod 23 while the rotating rod 23 rotates.

[0023] In the above scheme, the lower end of the rust removal tank 11 is connected to the sewage pipe 32. The sewage pipe 32 is equipped with a valve 33. When it is necessary to replace the pickling solution in the rust removal tank 11, the pickling solution can be discharged from the sewage pipe 32 by opening the valve 33.

[0024] Working principle:

[0025] In operation, this metal workpiece rust removal equipment involves placing the workpiece to be rusted in the placement basket 15, injecting the required pickling solution into the rust removal tank 11, and then turning on the electric push rod 14. The electric push rod 14 pushes the placement basket 15 at the lower end to immerse it in the rust removal tank 11 for rust removal. When the rust removal work begins, turning on the motor 2 causes the drive bevel gear 21 at the output end of the motor 2 to start rotating. The rotation of the drive bevel gear 21 drives the driven bevel gear 22, which is meshed on the side, to rotate. The rotation of the rotating rod 23 drives the stirring blade 25, which is fixed at the top, to start rotating. The stirring blade 25 causes the pickling solution to flow rapidly, and the flow of the pickling solution washes over the metal workpiece, thereby accelerating the separation of rust and metal and improving the efficiency of rust removal. After the rust removal work is completed, turning on the electric push rod 14 allows the metal workpiece to be easily removed from the rust removal tank 11.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
