Description

Technical Field

[0001] This utility model relates to the field of bearing processing, and in particular to an automatic pickling and phosphating line device for bearing forging production line. Background Technology

[0002] Phosphating is a process involving chemical and electrochemical reactions to form a phosphate conversion film, which is called a phosphate coating. Phosphating is a commonly used pretreatment technique, and in principle, it belongs to the category of chemical conversion film treatment. It is mainly used for phosphate coating of steel surfaces, but non-ferrous metal parts (such as aluminum and zinc) can also be phosphated. Before phosphate coating, the metal needs to be pickled, which refers to the method of removing oxide scale and rust from the surface of steel using an acid solution.

[0003] A search revealed Chinese Patent Publication No. CN209508421U, which discloses an acid pickling and phosphating device for metal and steel processing. The device includes a phosphating tank, a base fixedly connected to the bottom of the tank, and a control box fixedly connected to its side wall. A partition is fixedly connected to the inner wall of the phosphating tank, and the outer ring of a waterproof bearing is fixedly connected to the partition. A motor is fixedly connected to the bottom wall of the phosphating tank, and the motor's output shaft is fixedly connected to a rotating shaft via a coupling. The rotating shaft, after interference fitting with a waterproof bearing, is fixedly connected to a propeller-type stirring blade. A heating rod is provided on the upper surface of the partition. Limiting blocks are fixedly connected to the left and right inner walls of the phosphating tank, and guide rods are fixedly connected to the limiting blocks. The guide rods pass through and slide against a filter frame, and a filter screen is fixedly connected to the inner wall of the filter frame. The filter screen blocks large particles of phosphating waste.

[0004] Because the acidification or phosphating tanks are relatively large, the waste residue from acidification or phosphating is difficult to clean and collect after being filtered onto the filter screen. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4As shown, an automatic pickling and phosphating line device for a bearing forging production line includes a processing box 1. Support legs 101 are fixedly connected to the four corners of the bottom of the processing box 1. Drain pipes 102 are fixedly connected to both sides of the processing box 1. A control valve is installed inside the drain pipe 102. A partition 201 is fixedly connected between the inner walls of the processing box 1. The partition 201 divides the interior of the processing box 1 into a pickling tank 202 and a phosphating tank 203. A receiving tank is opened in the wall of the pickling tank 202 and the phosphating tank 203. An electric heating tube 3 is installed in the receiving tank. The solution is heated by the electric heating tube 3 to improve the efficiency of pickling or phosphating.

[0026] A filter plate 4 is detachably connected between the inner walls of the pickling tank 202 and the phosphating tank 203. A stirring assembly is provided below the filter plate 4. The stirring assembly includes a rotary motor 501 bolted to the bottom of the treatment box 1. A rotary shaft 502 is connected to the output shaft of the rotary motor 501 via a coupling. Several circumferentially arranged stirring blades 503 are fixedly connected to the outer wall of the rotary shaft 502.

[0027] The filter plate 4 is funnel-shaped, and a collection box 401 is detachably connected to the bottom of the filter plate 4. The collection box 401 is threaded to the bottom of the filter plate 4 and is grid-shaped. Several flushing holes 601 are opened around the top of the filter plate 4. The flushing holes 601 are inclined towards the filter plate 4. The walls around the pickling tank 202 and the phosphating tank 203 are provided with a liquid supply chamber 602 that communicates with the flushing holes 601. One end of the liquid supply chamber 602 is connected to the pickling tank 202 or the phosphating tank 203.

[0028] A squeezing mechanism is also provided below the filter plate 4. The squeezing mechanism is used to squeeze the solution in the pickling tank 202 or phosphating tank 203 into the supply chamber 602. The squeezing mechanism includes a squeezing plate 603 fixedly connected to the outer wall of the rotating shaft 502. The squeezing plate 603 is located below the stirring blade 503. The squeezing plate 603 is elastic and has an arc shape with the opening facing downward, which is conducive to increasing the flow rate of the solution generated by the downward squeezing of the squeezing plate 603.

[0029] The extrusion mechanism also includes a power assembly, which is used to drive the end of the extrusion plate 603 away from the rotating shaft 502 to move upward. The power assembly includes a connecting rod 604 fixedly connected to the end of the extrusion plate 603 away from the rotating shaft 502. The inner walls of the pickling tank 202 and the phosphating tank 203 are both fixedly connected to wedge blocks 605. During the rotation of the connecting rod 604, it abuts against the wedge blocks 605.

[0030] Working principle: During use, the bearing is placed inside the mesh cylinder, which is then lowered into the pickling tank 202 or phosphating tank 203 via a hook on the production line. The bearing is pickled in the pickling tank 202 to remove surface oxide scale and rust. Then, it undergoes phosphating in the phosphating tank 203 to form a phosphating film on the bearing surface. Simultaneously with pickling or phosphating, the rotary motor 501 is started. The rotary motor 501 drives the rotary shaft 502, which in turn rotates the stirring blades 503, turbulently flowing the solutions in the pickling tank 202 and phosphating tank 203 to ensure thorough contact between the solution and the bearing. The rotation of the rotary shaft 502 also drives the extrusion plate 603 to rotate. As the extrusion plate 603 rotates, it drives the connecting rod 604 to rotate as well. During the rotation of the connecting rod 604, it abuts against the wedge block 605. Under the guidance of the inclined surface of the wedge block 605, the connecting rod 604 drives one end of the extrusion plate 603 to tilt upward. When the connecting rod 604 separates from the wedge block 605, the end of the extrusion plate 603 moves downward under the action of elasticity, squeezing the solution in the pickling tank 202 or phosphating tank 203 through the liquid supply chamber 602 into the flushing hole 601. Finally, the solution sprayed out through the flushing hole 601 flushes the impurities filtered on the filter plate 4 into the collection box 401, which facilitates the collection of impurities.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
