Abstract

The invention relates to the field of workpiece cleaning, in particular to an aluminum alloy product cleaning method, which comprises the following steps of clamping a product, enabling the product to be opposite to a fixed nozzle capable of spraying hot water, feeding high-pressure hot water into the fixed nozzle, enabling the product to transversely move relative to the fixed nozzle and enabling the front end and the rear end of the product to pass through the fixed nozzle, stopping feeding high-pressure hot water into the fixed nozzle, feeding high-pressure gas into the fixed nozzle, transversely moving the product until the water drop removal rate of the surface of the product is greater than or equal to 60%, feeding high-pressure gas into a through hole communicated with an internal flow channel of the product until chips in the flow channel are discharged, and repeating the step 5 until the water drop removal rate of the surface of the product is greater than or equal to 90%, so that cleaning is completed.

Description

Aluminum alloy product cleaning method Technical Field The invention relates to the field of workpiece cleaning, in particular to a cleaning method for an aluminum alloy product. Background After the aluminum alloy product is processed, the aluminum alloy product needs to be cleaned in order to remove the scraps, greasy dirt and other dirt remained on the surface of the aluminum alloy product. At present, although automatic cleaning equipment exists, hot water can be adopted to flush an aluminum alloy product, but the contact area of the hot water and the aluminum alloy product is limited, so that the cleaning effect is often poor. After that, although the cleaning device for the aluminum alloy products assembled and disassembled by the automobile is shown as disclosed in the patent number CN206104442U, a plurality of aluminum alloy products are concentrated in the cleaning cage, and then the cleaning cage is rotated, so that hot water can be contacted with different parts of the aluminum alloy products, and the cleaning effect is improved. However, in actual production, after the cleaning is completed, the aluminum alloy product is moved to the next process to remove the water drops on the surface of the aluminum alloy product, and the disassembly, assembly and movement of the aluminum alloy product can definitely reduce the production efficiency, and the water drops on the surface of the aluminum alloy product can be dropped on the ground in the process of moving the aluminum alloy product, so that the production place is always in an excessively humid state, and thus the aluminum alloy product is easy to slip, and particularly when oil stains exist on the ground, the danger is greatly improved. Secondly, for the aluminum alloy product with the runner and the oil hole inside, the cleaning mode is difficult to discharge scraps inside the workpiece, so that the cleaning effect is poor. Disclosure of Invention The invention aims to provide a cleaning method for an aluminum alloy product, so as to solve the problem of poor cleaning effect. In order to achieve the purpose, the invention adopts the following technical scheme that the method for cleaning the aluminum alloy product is characterized by comprising the following steps: step 1, clamping a product, and then enabling the product to be opposite to a fixed nozzle capable of spraying hot water; step 2, high-pressure hot water is introduced into the fixed nozzle, and meanwhile, the product is transversely moved relative to the fixed nozzle, and the front end and the rear end of the product pass through the fixed nozzle; Step 3, stopping introducing high-pressure hot water, introducing high-pressure gas into the fixed nozzle, and transversely moving the product until the water drop removal rate of the surface of the product is more than or equal to 60%; Step 4, introducing high-pressure gas into the through hole communicated with the product internal flow channel until the scraps in the flow channel are discharged; And 5, repeating the step 3 until the water drop removal rate of the surface of the product is more than or equal to 90%, and finishing cleaning. Further, step 5 allows both the front and rear ends of the product to pass through the fixed nozzle at least once while repeating the operation of step 3. Furthermore, the water outlet tank is communicated with the fixed nozzle in the step 1, the water pump and the air pump are communicated with the water outlet tank, hot water is firstly introduced into the water outlet tank through the water pump in the step 2, and high-pressure gas is firstly introduced into the water outlet tank through the air pump after the water pump is firstly closed in the step3. In step 2, the temperature of the hot water is 45-100 ℃. Further, after the step 5 is completed, gas is firstly introduced into the periphery of the product until the water vapor around the product is discharged, and then the product is taken out. Further, step 1 firstly determines the position of a through hole communicated with the internal flow channel on the product, then moves the position of the air blowing nozzle to the moving path of the through hole, step 4 transversely moves the product to the position opposite to the air blowing nozzle, and then introduces high-pressure air into the product through the air blowing nozzle. And step 6, after finishing the step 5 for n times, introducing high-pressure gas under an arc plate of the flow guide assembly, and then closing the high-pressure gas, wherein n is an integer greater than or equal to 2. The beneficial effect of this scheme is: 1. This scheme is washing the back to the product, can get rid of drop on product surface and aluminium bits fast through high-pressure gas for can accomplish the washing and the weather of product in a process, also prevent that the water droplet on the product from falling subaerial when improving efficiency. Meanwhile, the product slides relative to the fixed nozz
