Wuxi IDEAL Machinery Manufacturing Co., Ltd. is discussing with you about the manufacturer of shot blasting machine:how to manage the shot blasting machine.

As the manufacturer of shot blasting machine: the shot blasting machine needs to deal with various metal casting surface adhesion cleaning, surface rust removal of ferrous metal parts, surface burr and burr rounding of stamping parts, surface treatment of forgings and heat treated parts, as well as surface oxide scale removal and surface grain refinement, all of which can be achieved through the shot blasting strengthening process of this series of equipment. It has a wide range of applications, including foundries, heat treatment plants, motor plants, machine tool parts plants, bicycle parts plants, power machine plants, automobile parts plants, motorcycle parts plants, non-ferrous metal die-casting plants, etc.

After shot blasting, the workpiece can obtain good material color, and also become the previous process of blackening, bluing, passivation and other processes on the surface of metal parts. At the same time, it can provide a good base surface for electroplating, painting and other finishing. After shot blasting by the shot blasting machine, the tensile stress of the workpiece can be reduced, and the surface grain can be refined, so as to strengthen the surface of the workpiece and increase its service life.

(1) Control of current (shot flow) of shot blaster. The greater the flow of pellets, the faster the cleaning speed. Since the shot flow cannot be displayed, it is displayed by the current of the shot blaster motor. The greater the shot flow, the greater the current. The process management controls the current. The current is one of the important parameters of shot blasting, which is regulated by the number of shot particles and the control valve of shot conveying pipeline. From the perspective of equipment use, the current should not be too high, and should reach 80% - 90% of the rated current, that is, the reading should be controlled at 23.8-31.5A (18.5kW motor). First adjust the control valve of the shot conveying pipeline so that the current of the eight shot blasters is basically the same, which is controlled at about 30A, and mark the control valve. Adjustment is not allowed without the consent of the process personnel. The best current parameters are selected by throwing different workpieces and adjusting the current for multiple groups of tests. The conclusion is that the effect of shot peening is better when the current is 20-25A, the effect is worse when the current is lower than 15A, and the workpieces are obviously unqualified when the current is lower than 10A, so the current process is set at 15-30A, and the daily control is 20-25A. The control of daily current depends on the amount of pellets. With the progress of production, the shot particles are worn and broken into dust, and the total amount of shot particles is decreasing, and the current is decreasing. It is necessary to add shot particles in time to ensure that the current is controlled within the process range. The supplementary amount of each shift shall be added according to the product of quota and output. In special cases, the supplementary amount shall be added according to the instructions of the technologist.
