The current pattern of China's auto market is that international capital takes 40% of the capital, occupying 50% of the market share, and grabbing 70% of the profit. As the price war of the entire car is passed on to the parts, almost every auto parts company has Facing a problem of enhancing core competitiveness, mastering and using advanced manufacturing technology is the most important part of enhancing core competitiveness. In order to comply with the more demanding requirements for cars to be more stable and safer, more energy-saving, reduce noise, and pollutant emissions, aluminum alloy wheels are developing towards the goal of lightweight, wide wheel transmission, high strength, and more beautiful appearance. Therefore, deburring and surface treatment of the wheel hub before leaving the factory is very necessary to meet the requirements of beauty and durability.
At present, the surface processing of domestic aluminum alloy wheels basically adopts manual polishing, mechanical shot peening and shot blasting, and then chemical pretreatment including degreasing, pickling and phosphating methods to achieve final cleanliness and certainty. Smooth surface. The common problems of these traditional processing methods are: (1) The technical requirements for workers are high and the labor intensity is relatively high, and the working environment is very harsh; (2) The process stability and product consistency are poor; (3) The environmental pollution is serious; (4) ) Low production efficiency.
The abrasive flow polishing process is one of the solutions to this type of problem.
This process has been widely used in the finishing of auto parts: intake and exhaust pipes, intake valves, booster chambers, fuel injectors, fuel injectors, cylinder heads, turbine housings and blades, splines, gears, brakes, etc. .
Abrasive flow polishing technology is an economical and effective new precision finishing process. Abrasive flow polishing technology has many processing advantages, such as high polishing efficiency, automatic production, good controllable performance, and high polished surface quality. Compared with traditional machining methods, abrasive flow polishing technology can use the fluidity of abrasive media to polish complex structure holes and cavity deep holes. It can also select different abrasive media to perform parts according to the application requirements of the parts. Polishing to obtain different polishing effects to meet the requirements of parts
Manufacturing processes
The equipment structure includes a frame 13. The top of the frame 13 is symmetrically provided with a left propulsion cylinder I and a right propulsion cylinder 3, and an upper power cylinder 2 is provided between the left propulsion cylinder 1 and the right propulsion cylinder 3. The cylinder 2 is connected to the upper abrasive cylinder 4, and the upper abrasive cylinder 4 is installed above the workpiece cover 7 and supported by the guide rod 5. The workpiece cover 7 is provided with a transmission component 9 connected to the motor workpiece rotation control system 10 in the middle, and under the workpiece cover 7 A lower abrasive cylinder 11 is provided, which is fixed on the lower power cylinder 12, and also includes an overall PLC automation control system panel 14. The overall PLC automation control system panel is fixed on the side of the lower bracket in the frame 13, and the motor workpiece The control circuit system of the rotation control system 10 is connected with the overall PLC automation control system, and the hydraulic control device circuit system on the frame 13 is also connected with the overall PLC automation control system. The workpiece cover 7 is fixed by a slewing bearing 6.
During processing, the prepared fluid abrasive particles are discharged into the lower abrasive cylinder 11 through a special pipe, and the whole lower abrasive cylinder 11 is filled with it, and then let stand for 0.5 min to ensure that the fluid abrasive particles evenly fill the cavity of the abrasive cylinder, and then clean the hub 8 On the surface, the left propulsion cylinder 1, the right propulsion cylinder 3 and the upper power cylinder 2 are controlled through the PLC control panel, and the upper abrasive cylinder 4 is pushed down along the guide rod 5 to compress the workpiece cover 7, and the workpiece cover 7 is fixed and made to be with the motor workpiece The rotary control system 10 is connected, the processing time is set to 4 min, the processing pressure is set to 10 MPa, and the processing speed is 0.05 m/min. When working, put the hub 8 between the upper and lower pressure plates of the workpiece cover 7, and press it with a hydraulic device, and then use the proportional valve controlled by the PLC automation control system panel 14 to limit the abrasive flow drive device, and at the same time follow It is required to drive the reciprocating and spiral flow of abrasive particles to achieve the purpose of deburring the surface of the wheel hub.
Advantages of using abrasive flow to deburr
