[0005] Chinese patent, polishing wheel cleaning process (application number: 201210196235.3), its innovation lies in the use of high-pressure cleaning, the cleaning process of cleaning agent solution is added, and the cleaning process is divided into two steps of pre-cleaning and cleaning, in different steps Using different concentrations, pressures, and times of cleaning solutions, this technical solution has higher requirements for the cleaning effect of the cleaning solution, and does not solve the problem of wheel anti-corrosion performance
[0006] Thesis, Aircraft Parts Cleaning Process Research and Equipment Development (2013, Dalian University of Technology, Tian Shaoyang, Master of Machinery Manufacturing and Automation), proposed a spray cleaning method in the paper, that is, using the water jet principle for cleaning, considering The cost of cleaning agents and corresponding equipment listed in the paper is relatively high, which does not meet the cleaning needs of large quantities of aluminum alloy wheels

Embodiment 1
[0032] To clean aluminum alloy wheels, use the following steps:
[0033] Step 1, automatic loading, and use a magnetic device to scan the surface of the wheel for 1-2 times;
[0034] Step 2, hot water washing, use distilled water at 60°C to wash the wheels, and the washing time is 1.5 minutes;
[0035] Step 3, pre-degreasing treatment, choose the configured degreasing solution for washing, the degreasing solution requires a degreasing agent concentration of 1.0%, a temperature of 70 ° C, a pH value of 9, a pressure of 0.15 MPa, and a washing time of 2.75 min;
[0036] Step 4, degreasing treatment, choose the prepared degreasing solution for rinsing, the degreasing solution requires a degreasing agent concentration of 2.2%, a temperature of 70 ° C, a pH value of 9, a pressure of 0.15 MPa, and a rinsing time of 5 minutes;
[0037] Step 5, clean water treatment, place the wheel in a normal temperature clean waterpool to soak for 5 minutes, and then rinse it with normal temperat...
Embodiment 2
[0045] To clean aluminum alloy wheels, use the following steps:
[0046] Step 1, automatic feeding;
[0047] Step 2, hot water washing, before step 2, use 70°C distilled water to soak the wheels for 45s, and then use 75°C distilled water to wash the wheels for 45s;
[0048] Step 3, pre-degreasing treatment, choose the configured degreasing solution for washing, the degreasing solution requires a degreasing agent concentration of 0.8%, a temperature of 80 ° C, a pH value of 8, a pressure of 0.1 MPa, and a washing time of 2.5 minutes;
[0049] Step 4, degreasing treatment, choose the prepared degreasing solution for rinsing, the degreasing solution requires a degreasing agent concentration of 2.4%, a temperature of 80 ° C, a pH value of 10, a pressure of 0.2 MPa, and a rinsing time of 5 minutes;

Abstract
A cleaning method of an aluminum alloy wheel comprises automatic feeding, hot water cleaning, pre-degreasing, degreasing, clean water treatment, micro acid treatment, first-time distilled water treatment, passivation treatment, second-time distilled water treatment, baking and automatic blanking. By means of the cleaning method, pointed treatment means are performed on metal waste, dust, greasy dirt and the like which may be generated and are attached to the surface of the wheel in the wheel machining process; and meanwhile, waste generated in the cleaning process of the wheel is substantially reused, environmental friendliness and low consumption are achieved, and cost is reduced.
Description
technical field [0001] The invention relates to the field of wheel processing, in particular to a cleaning method for aluminum alloy wheels. Background technique [0002] Wheel manufacturing is an indispensable part in the manufacture of automobiles, motorcycles and other vehicles. In actual production, when the wheels are just produced, there may be metal chips and oil stains on the surface. In order to ensure the clean and beautiful appearance of the wheels, at the same time, improve the To enhance the adhesion between the paint and the aluminum surface and enhance the anti-corrosion performance of the wheels, the wheels need to be cleaned. [0003] The wheel cleaning process of existing traditional technology is as follows: degreasing, passivation, finally rinses with clear water. [0004] Chinese patent, a production process of aluminum alloy wheels (application number: 201310686130.0), has a cleaning step, and its technical scheme is as follows: degrease, surface adjus...
