Description

Technical Field

[0001] The utility model belongs to the field of electrolytic polishing, in particular to a stainless steel pipe polishing device. Background Art

[0002] Electrolytic polishing of stainless steel uses the workpiece being polished as the anode and an insoluble metal as the cathode. Both electrodes are immersed in an electrolytic bath and a direct current is applied to each. This dissolves the workpiece (the anode) and gradually smoothes the surface, achieving the desired polishing effect. The main advantages of electrolytic polishing of stainless steel are: 1. Consistent color and long-lasting gloss inside and out; 2. High production efficiency and low processing costs; 3. Optimized corrosion resistance of the workpiece surface, suitable for complex structures.

[0003] Static electrolyte in the electrolytic tank is less efficient than flowing electrolyte. To keep the electrolyte flowing, existing solutions typically incorporate stirring and electrolyte circulation mechanisms within the tank. However, existing stirring mechanisms take up considerable space within the tank and pose a risk of impacting the workpiece being polished, leaving much room for improvement. Utility Model Content

[0018] Reference Figure 1 and Figure 2 The utility model discloses a stainless steel pipe polishing device, comprising an electrolytic cell 11, the inner cavity of the electrolytic cell 11 is oblong, the electrolytic cell 11 is provided with a diverter plate 12, the diverter plate 12 extends along the length direction of the oblong, the head and tail ends of the diverter plate 12 do not contact the inner wall of the electrolytic cell 11, the left and right sides of the electrolytic cell 11 are divided into chambers of different widths by the diverter plate 12, the chamber with a larger width is used to place the stainless steel pipe, the axial centerline direction of the stainless steel pipe is parallel to the length direction of the electrolytic cell 11, and the chamber with a smaller width is used for electrolyte reflux. The device also includes two stirring mechanisms, each comprising a first crossbar 21 located above, a fan bracket 22 located below, a motor 23 mounted on the first crossbar 21, a spiral blade 24 mounted on the fan bracket 22, and its transmission member. The motor 23 drives the spiral blade 24 to rotate via the transmission member. The two stirring mechanisms are installed in the wider chamber of the electrolytic cell 11, one at the head and the other at the tail. The two spiral blades 24 rotate to drive the electrolyte flow. The device also includes two pipe racks, each comprising a second crossbar 31 located above and several support rods 32 located below. Stainless steel pipes are placed on the support rods 32.

[0019] This solution uses spiral blades 24 at both ends to push the electrolyte, so that it forms a circulating flow state. In this process, the position where the stainless steel pipe is placed is cleverly avoided, and the two do not affect each other and operate independently. At the same time, this flowing electrolyte can significantly improve the polishing efficiency. When the electrolyte needs to be replenished, it can be poured into the narrower side of the electrolytic cell 11. Under the action of gravity and other factors, the electrolyte can naturally be integrated into the circulation system. In addition, the inner wall of the electrolytic cell 11 adopts an oblong structure design. This unique design greatly reduces the flow dead angle, creates favorable conditions for the smooth flow of the electrolyte, and further optimizes the operation effect of the entire system.

[0022] As an improvement to the above solution, a horizontal skirt is provided at the upper edge of the electrolytic cell 11, and both the first and second crossbars 31 are secured to the skirt at both ends via bolts. This solution increases the contact area between the electrolytic cell 11 and the first and second crossbars 21 and 31, thereby improving the stability of the first and second crossbars 21 and 31.

[0023] As an improvement of the above scheme, the transmission member includes a vertical first transmission rod and a horizontal second transmission rod, the first transmission rod and the second transmission rod are connected by a bevel gear, one end of the first transmission rod is connected to the motor 23, and one end of the second transmission rod is connected to the spiral blade 24.

[0024] As an improvement to the above solution, the narrow chamber of the electrolytic cell 11 is provided with spoilers at different heights. The spoilers are tilted to adjust the up and down flow direction of the electrolyte. When the supplementary liquid is added to this side of the electrolytic cell 11, it is conducive to the thorough mixing of the electrolyte.
