Description

Stainless steel surface polishing device

Technical Field

The invention belongs to the technical field of stainless steel workpiece processing, and in particular relates to a stainless steel surface polishing device.

Background Art

Stainless steel is made of iron-chromium alloy mixed with some other trace elements. Stainless steel can be divided into three categories according to its metallographic structure: austenitic stainless steel, ferritic stainless steel and martensitic stainless steel. The main components of stainless steel are iron, chromium and nickel alloys. In addition, it also contains trace elements such as manganese, titanium, cobalt, molybdenum and cadmium, which makes stainless steel have stable performance, stainlessness and corrosion resistance. During production and processing, it is necessary to use a polishing machine to polish it and remove burrs.

During the polishing process, abrasive chips are easily attached to the polishing machine. As the polishing process progresses, the abrasive chips rub against the stainless steel surface, causing damage to the surface. This will not only increase the wear of the polishing machine and increase the cost of use, but will even affect the machining accuracy of parts with high precision requirements. Therefore, eliminating the influence of abrasive chips from the polishing device can effectively improve the polishing effect.

In this embodiment, a planetary gear assembly 16 is arranged between the electrostatic generator 1 and the mounting seat 4, and the planetary gear assembly 16 includes a sun gear 17, a planetary gear 18, and two ring gears 19. The sun gear 17 is fixed on the output shaft of the drive motor 3, and the planetary gears 18 surround the sun gear 17. The shaft of the planetary gear 18 is rotatably connected to the electrostatic generating box 1 through a bearing. The planetary gears 18 are respectively meshed with the sun gear 17 and the ring gear 19. A negative panel 20 and a positive panel 21 are arranged between the electrostatic generator 1 and the mounting seat 4. The two ring gears 19 are respectively fixedly sleeved on the negative panel 20 and the positive panel 21. The upper side of the negative panel 20 contacts the negative brush 14, and the lower side of the positive panel 21 contacts the positive point 15.

In this embodiment, the first conductive rod 22 and the second conductive rod 22 are alternately distributed below the positive panel 21, and through holes with a cross-sectional diameter larger than the diameter of the first conductive rod 22 are evenly distributed on the positive panel 21. The first conductive rod 22 passes through the positive panel 21, and insulating material is filled between the first conductive rod 22 and the through hole of the positive panel 21 for insulation treatment. The upper end of the first conductive rod 22 is fixedly connected to the lower side of the negative panel 20, and the upper end of the second conductive rod 23 is fixedly connected to the lower side of the positive panel 21. The lower ends of the first conductive rod 22 and the second conductive rod 23 are fixedly connected to the collecting panel 24, and the height of the lower edge of the collecting panel 24 is higher than the height of the lower edge of the polishing turntable 5.

In this embodiment, the electrostatic generator 1 is made of flame-retardant PP plastic.

In this embodiment, the first roller 9 is made of polytetrafluoroethylene material that easily attracts electrons.

In this embodiment, the second roller 10 is made of aluminum which is easy to lose electrons.

In this embodiment, the belt 11 is made of neutral cotton.

In this embodiment, the concave bracket 13 is made of copper material with good electrical conductivity.

In this embodiment, the arc-shaped outer wall of the gear ring 19 is covered with a rubber pad for insulation treatment.

In this embodiment, when the polishing device is polishing the stainless steel surface, the output shaft of the driving motor 3 rotates, driving the polishing turntable 5 to rotate, and the output shaft of the driving motor 3 drives the first roller 9 and the second roller 10 to rotate by the cooperation of the first gear 7 and the second gear 8. At the same time, through the driving effect of the planetary gear assembly 16, the negative electrode panel 20 and the positive electrode panel 21 rotate differentially relative to the polishing turntable 5;

Due to the triboelectric effect, when the first roller 9 drives the belt 11 to rotate, friction is generated between the first roller 9 and the belt 11, and electrons jump from the belt 11 to the first roller 9, so that the first roller 9 has a negative charge and the belt 11 has a positive charge. Since like charges repel each other, the electrons at the tip of the metal comb teeth 12 on the left are discharged and flow to the collecting panel 24 of the first conductive rod 22 through the concave bracket 13, the negative electrode brush 14, and the negative electrode panel 20 in sequence, forming an electric field between the first roller 9 and the left metal comb teeth 12, so that the electrons in the air between the first roller 9 and the left metal comb teeth 12 are separated from the molecules and move to the left metal comb teeth 12. The positively charged ions in the air cannot contact the first roller 9 due to the obstruction of the belt 11, so the positively charged ions in the air are coated on the belt 11. The outer surface of the belt 11 moves to the second roller 10 along with the belt 11. The positively charged belt 11 rubs against the second roller 10, and the electrons on the second roller 10 of the aluminum material are transferred to the belt 11, so that the second roller 10 is positively charged. The second roller 10 attracts the electrons on the right metal comb teeth 12 to the tip area of the comb teeth to form another electric field. The electrons in the air are separated from the molecules and move to the second roller 10. The positively charged ions in the air are attracted to the metal comb teeth 12 on the right, and flow to the collecting panel 24 of the second conductive rod 23 through the concave bracket 13, the positive electrode brush 15, and the positive electrode panel 21 in turn, and finally the electrons are gathered on the collecting panel 24 connected to the first conductive rod 22, and the positively charged ions are gathered on the collecting panel 24 connected to the second conductive rod 23, and an electric field is formed between adjacent collecting panels 24;

As the abrasive chips generated by the polishing turntable 5 during the polishing process are thrown out, the negatively charged abrasive chips are attracted to the collection panel 24 with positive ions, and the positively charged abrasive chips are attracted to the collection panel 24 with electrons. At the same time, the neutral abrasive chips close to the positively charged ion collection panel 24 lose electrons and are transformed into positively charged abrasive chips, and then move in the electric field and are collected by the collection panel 24. The neutral abrasive chips close to the collection panel 24 with concentrated ions obtain the electrons released on the collection panel 24 and are transformed into negatively charged abrasive chips, and then move in the electric field and are collected by the collection panel 24. Since the collection panel 24 rotates differentially relative to the polishing turntable 5, the neutral abrasive chips that are exactly located in the middle of the adjacent collection panels 24 are subsequently deviated from the rotation position of the collection panel 24, and are finally converted into charged abrasive chips and collected. As the charged abrasive chips are continuously collected on the collection panel 24, the charge on the collection panel is continuously neutralized, and the frictional electric effect replenishes the charge on the collection panel 24 in real time to maintain the electric field between the adjacent collection panels 24, thereby ensuring the continuity of abrasive chip collection.

Embodiment 2: As shown in FIG. 2-3, on the basis of Embodiment 1, a first collecting box 25 and a second collecting box 26 are alternately distributed between the installation panel 2 and the electrostatic generator 1 around the driving motor 3, wherein the first collecting box 25 corresponds to the first conductive rod 22 one by one, and the second collecting box 26 corresponds to the second conductive rod 23 one by one, and the first collecting box 25 and the second collecting box 26 are both connected to the collecting pipe 27, the lower end port of the collecting pipe 27 is an enlarged trumpet-shaped structure, and the lower end of the collecting pipe 27 is located on the outer side of the corresponding collecting panel 24, and an exhaust box 28 is fixed on the upper side of the installation panel 2, and the exhaust box 28 is fixed on the upper side of the installation panel 2, and a partition 2801 is arranged in the middle of the exhaust box 28, and the partition 2801 separates the exhaust box 28 is divided into an upper cavity 29 and a lower cavity 30, wherein both the upper cavity 29 and the lower cavity 30 are provided with a discharge port, the exhaust port is connected to the grinding chip collection device through a pipeline, or is away from the working area of stainless steel polishing, and an exhaust fan 31 is arranged in the discharge port, a first connecting pipe 32 is arranged between the first collecting box 25 and the upper cavity 29, the first connecting pipe 32 passes through the lower cavity 30, and one end of the first connecting pipe 32 is connected to the upper cavity 29, and the other end of the first connecting pipe 32 is connected to the first collecting box 25, a second connecting pipe 33 is arranged between the second collecting box 26 and the lower cavity 30, the upper end of the second connecting pipe 33 is connected to the lower cavity 30, and the lower end of the second connecting pipe 33 is connected to the second collecting box 26.

In this embodiment, electrons are gathered on the collection panel 24 connected to the first conductive rod 22 to collect positively charged abrasive chips that have lost electrons. Under the action of the exhaust fan 31, positively charged abrasive chips that escape from the lower side of the electron-collecting collection panel 24 due to large particles or less electron loss and lower charge are sucked into the first collection box 25 through the corresponding collection tube 27. The electrons on the first collection box 25 and the lower port of the collection tube 27 connected by the wire are transferred to the abrasive chips, showing positive charge. Under the action of electrostatic induction, the abrasive chips that carry excess electrons and show negative charge are attracted to enter the second collection box 26. Positively charged ions are gathered on the collection panel 24 connected to the second conductive rod 23 to collect negatively charged abrasive chips that carry excess electrons. Under the action of the exhaust fan 31, the positively charged ions are gathered on the collection panel 24 connected to the second conductive rod 23 to collect negatively charged abrasive chips. The abrasive chips that escape from the lower side of the positively charged ion collection panel 24 due to large particles or less electrons and lower charge are sucked into the second collection box 26 through the corresponding collection tube 27. The electrons on the abrasive chips are transferred to the second collection box 26 and gathered through the wire to the lower port of the corresponding collection tube 27 of the adjacent first collection box 25 to show negative charge. Under the action of electrostatic induction, the abrasive chips that have lost electrons and show positive charge are attracted to enter the first collection box 25. As the above process continues, positive feedback is achieved, and the electrostatic induction between the lower port of the collection tube 27 and the abrasive chips is continuously strengthened. The abrasive chips are further collected by cooperating with the airflow generated by the exhaust fan 31. By collecting the abrasive chips, the friction between the generated abrasive chips and the stainless steel surface is avoided, thereby improving the polishing efficiency.
