Problems solved by technology

Due to the large size of the tank, ordinary polishing equipment cannot fully polish the tank, especially the all-round polishing of the inside and outside of the tank
The polishing accuracy of mechanical polishing is limited, and chemical polishing or electrolytic polishing alone cannot deeply polish the surface of large tanks, resulting in unsatisfactory polishing results

Embodiment 1

[0068] (1) mechanical polishing, the inner and outer walls of the head 52 and the barrel 53 of the tank body 3 are respectively polished synchronously by the polishing device 1;

[0069] (2) degreasing and degreasing, cleaning the tank body 3 after mechanical polishing;

[0070] (3) Electrolytic polishing, add electrolytic polishing solution in the electrolytic cell, heat to 65°C with a titanium heating rod, stop heating after reaching the required temperature, hoist the tank body 3 into the electrolytic cell, and connect the tank body 3 as the anode, the insoluble metal as the cathode, and the second stage is set in the electrolytic cell at the same time, turn on the power rectifier switch, adjust the voltage to 12V, control the working current at 2500A, and the polishing time is 35 minutes;

[0071] (4) Soaking and washing, soaking the electropolished tank body 3 in the clear water tank for 15 minutes, washing it with clear water, and then drying or air-drying.

Embodiment 2

[0073] (1) mechanical polishing, the inner and outer walls of the head 52 and the barrel 53 of the tank body 3 are respectively polished synchronously by the polishing device 1;

[0074] (2) degreasing and degreasing, cleaning the tank body 3 after mechanical polishing;

[0075] (3) Electrolytic polishing, add electrolytic polishing solution in the electrolytic cell, heat to 30°C with a titanium heating rod, stop heating after reaching the required temperature, hoist the tank body 3 into the electrolytic cell, and connect the tank body 3 as the anode, the insoluble metal as the cathode, and the second stage is set in the electrolytic cell at the same time, turn on the power rectifier switch, adjust the voltage to 12V, control the working current at 2500A, and the polishing time is 35 minutes;

[0076] (4) Soaking and washing, soaking the electropolished tank body 3 in the clear water tank for 15 minutes, washing it with clear water, and then drying or air-drying.

Embodiment 3 to Embodiment 8

[0078] The polishing methods of Examples 3 to 8 are the same as in Example 1, except that the temperatures in the electrolytic polishing are different, which are 40°C, 50°C, 55°C, 60°C, 70°C, and 80°C respectively, and the roughness of the inner and outer surfaces The performance test is shown in Table 1.

[0079] The roughness property test of table 1 embodiment 1~8

Abstract

The invention provides a surface polishing system and a polishing method thereof. The system comprise polishing equipment, wherein the polishing equipment comprises a transmission mechanism, a side polishing mechanism and an inner polishing mechanism, wherein the side polishing mechanism is movably arranged between the transmission mechanism and the inner polishing mechanism, the transmission mechanism comprises a positioning screw rod, a positioning frame and a transmission disc, the positioning frame is connected with the positioning screw rod and the transmission disc, the positioning framemoves up and down along with the rotation of the positioning screw rod, the outer edge of the transmission disc is connected with supporting legs of a tank body, so that the tank body rotates along with the rotation of the transmission disc, the side polishing mechanism is provided with two pairs of side polishing wheels, the side polishing wheels are adjustably attached to the outer wall of thetank body so as to polish the outer side of the tank body, the inner polishing mechanism is provided with an inner polishing wheel, the inner polishing wheel extends to the inner wall of the tank bodyin an extendable adjusting mode, so that comprehensive polishing of the inner part and the outer part of the large tank body is realized, the cost is saved, and the benefits are improved.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a surface polishing system suitable for tank bodies and a polishing method thereof. Background technique [0002] After the tank body is processed and formed in various processes, it is necessary to polish the girth weld, straight weld seam and the surface of the tank body. The commonly used polishing methods include mechanical polishing, chemical polishing and electrolytic polishing. The processing technology of abrasive particles and soft tools on the surface of parts. During the polishing process, the interaction between abrasive particles and the surface of the workpiece has three states: sliding, plowing and cutting. In these three states, the grinding temperature and grinding force are increasing. Yes, since the abrasive grains are attached to the soft matrix, the abrasive grains will shrink back into the soft matrix to varying degrees under the action of the grinding for...
