[0002] Metal products are structural metal products. The most well-known metal product processing method is sand mold casting. This method has low cost and small batch size, and can process complex shapes, but may require a large number of post-processing procedures. Metal products are prone to rusting on the surface, so it is often necessary to remove rust and clean the surface of rusty metal products; However, for the existing rust removal and cleaning devices for the surface of metal products, most of them use single methods such as grinding or sandblasting to remove rust and clean the surface of metal products, which reduces the rust removal and cleaning effect on the surface of metal products, and it is difficult to firmly clamp metal products. The movement of metal products during the rust removal and cleaning process may cause some parts not to be rust-removed and cleaned. At the same time, it is also difficult to intelligently adjust the rust removal and cleaning process on the surface of metal products to improve the rust removal and cleaning effect on the surface of metal products; Therefore, it is very necessary to design a rust removal and cleaning device for surface treatment of metal products.

The pickling duration factor of the rust removal acid solution represents the duration data collected by the timer for the pickling of metal products in the acid solution storage tank, and the sandblasting volume factor represents the sandblasting volume data obtained by multiplying the sandblasting flow rate of a single sandblasting nozzle collected by the flow detector by the number of sandblasting nozzles and the sandblasting time of the sandblasting nozzle; The data analysis module then performs the metal product rust removal and cleaning control analysis operation based on the received rust removal working condition information on the surface of metal products during the rust removal and cleaning process.

The horizontally moving circular block can drive the moving cylinder to move longitudinally through the sliding connection with the ring body, and then drive the mounting frame to move upward, increasing the distance between the sandblasting nozzle and the metal product to be rust removed, and increasing the impact force of the sand falling on the surface of the metal product to be rust removed. At the same time, the high-pressure water spray head is started to pressurize the water in the water storage tank and spray it onto the surface of the metal product to be rust removed for secondary rust removal treatment of the surface of the metal product to be rust removed.

By combining the above pickling, sand spraying and high-pressure water spraying methods to derust and clean the surface of the metal product, the derusting and cleaning effect on the surface of the metal product is improved; The present invention collects the derusting working condition information on the surface of the metal product during the derusting and cleaning process through the data collection module in the control panel, and transmits the collected information to the data analysis module. Through the data analysis module, excellent process signals, general process signals and poor process signals are obtained, and the obtained signals are transmitted to the execution module through the processor.

The pickling duration factor of the rust removal acid solution represents the duration data collected by the timer (25) for the pickling of the metal product in the acid solution storage tank (2), and the sand spraying amount factor represents the sand spraying amount data obtained by multiplying the sand spraying flow rate of a single sandblasting nozzle (28) collected by the flow detector (29) by the number of sandblasting nozzles (28) and the sandblasting time of the sandblasting nozzle (28); The data analysis module then performs metal product rust removal and cleaning control analysis operations based on the received rust removal working condition information on the surface of the metal product during the rust removal and cleaning process. The specific steps are as follows: A: Obtain the rust removal working condition information on the surface of the metal product during the rust removal and cleaning process, and respectively calibrate the pickling duration factor of the rust removal acid solution and the sand spraying amount factor therein as D and E; B: According to the formula: R = (D*a + E*b) / 2, obtain the rust removal level R on the surface of the metal product during the rust removal and cleaning process. Both a and b are process correction factors, E = s*n*t, s is the sand spraying flow rate of a single sandblasting nozzle (28), n is the number of sandblasting nozzles (28), t is the sandblasting time of the sandblasting nozzle (28), and a > b > 0; C: When the rust removal level R on the surface of the metal product during the rust removal and cleaning process is greater than the maximum value of the preset range r, within the preset range r, or less than the minimum value of the preset range r, a process excellent signal, a process normal signal, and a process poor signal are generated respectively; And the process excellent signal, the process normal signal, and the process poor signal are transmitted to the execution module through the processor.
8. The rust removal and cleaning equipment for surface treatment of metal products according to claim 7, characterized in that, The specific operation process of the execution module is as follows: After receiving the process excellent signal, the execution module does not perform any processing; After receiving the process normal signal, the execution module starts the electric push rod (37) to work, driving the circular block (35) to move horizontally. The horizontally moving circular block (35) can drive the moving cylinder (33) to move longitudinally through the sliding connection with the ring body (36), and then drive the mounting bracket (10) to move upward, increasing the distance between the sandblasting port (28) and the metal product to be rust removed (3), and increasing the impact force of the sand falling on the surface of the metal product to be rust removed (3); After receiving the process poor signal, the execution module starts the electric push rod (37) to work, driving the circular block (35) to move horizontally. The horizontally moving circular block (35) can drive the moving cylinder (33) to move longitudinally through the sliding connection with the ring body (36), and then drive the mounting bracket (10) to move upward, increasing the distance between the sandblasting port (28) and the metal product to be rust removed (3), and increasing the impact force of the sand falling on the surface of the metal product to be rust removed (3). At the same time, the high-pressure water nozzle (27) is started to pressurize the water in the water storage tank (11) and spray it onto the surface of the metal product to be rust removed (3) for secondary rust removal treatment of the surface of the metal product to be rust removed (3).
