Method and equipment for cleaning workpiece and method and equipment for cleaning tire loose die

Abstract

The invention provides a method and equipment for cleaning a workpiece and a method and equipment for cleaning a tire loose die. The method for cleaning the workpiece comprises the steps that the workpiece is heated to a preset temperature; and a water-based solution is applied to the workpiece and is instantly vaporized, micro explosion is formed at all impact points, dirt is stripped off from the workpiece, and the workpiece is cleaned. The equipment for cleaning the workpiece comprises a heating device and a cleaning device. The heating device is used for heating the workpiece to a preset temperature range. The cleaning device is used for applying the water-based solution to the workpiece, enabling the water-based solution to be vaporized instantly to form micro explosion at all the impact points, stripping off of the dirt from the workpiece and cleaning of the workpiece. Dirt on the surface of the workpiece can be cleaned off, and great breakthroughs are obtained in cleaning of micron-order or nano-scale clearances of the workpiece; and the beneficial effects that the cost is low, cleaning is easy, and dirt is thoroughly removed are achieved.

Description

Technical field [0001] The present invention relates to a cleaning technology applied to the field of workpiece cleaning, in particular to a method and equipment for cleaning a workpiece, and a method and equipment for cleaning a non-porous tire movable mold. Background technique [0002] At present, the cleaning methods adopted by some industrial and mining enterprises in my country are mainly chemical cleaning, mechanical cleaning, high-pressure water cleaning, dry ice cleaning, laser cleaning, etc. [0003] Chemical cleaning includes organic solvent method, melting method, pickling method, alkaline washing method, etc. Long-term use of the above methods will cause corrosion of the workpiece, which directly affects the appearance and quality of the product, and also has certain pollution to the environment. [0004] Mechanical cleaning includes manual grinding, sand grinding, etc. The mechanical washing method avoids chemical corrosion, but after repeated grinding and cleaning, the...

AI Technical Summary

Problems solved by technology

[0003] Chemical cleaning includes organic solvent method, melting method, pickling method, alkali cleaning method, etc. Long-term use of the above methods will cause corrosion of the workpiece, which will directly affect the appearance and quality of the product, and also pollute the environment to a certain extent

[0004] Mechanical cleaning includes manual grinding, gravel grinding, etc. Mechanical cleaning avoids chemical corrosion, but after repeated grinding and cleaning, the precision of the workpiece will decrease, and it will cause dust pollution

[0005] High-pressure water cleaning is to use the power device to make the high-pressure plunger pump generate high-pressure water to wash the surface of the object, peel off and wash away the dirt, and the cleaning is not thorough if the pressure is small, and the high pressure will cause damage to the workpiece and increase the labor intensity and safety risks of the operator.

[0006] Dry ice blasting is the acceleration of dry ice particles in the high-pressure airflow, impacting the surface to be cleaned, so that the dry ice particles are gasified at the moment of impact. Due to the temperature difference between the dry ice particles and the cleaning surface, thermal shock occurs, and the temperature of the material decreases and the brittleness increases. , dry ice particles can impact and break the dirt layer, but as a solid carbon dioxide, dry ice has poor fluidity, and the cleaning effect on the corners of the workpiece is not ideal, especially the inner cavity of the workpiece is almost impossible to clean

[0007] Laser cleaning is to use the difference between the substrate material of the workpiece and the dirt attached to the surface on the laser energy absorption coefficient of a certain frequency, so that the laser energy is fully absorbed by the dirt attached to the surface, and then expands when heated until it is vaporized to achieve the purpose of cleaning. Efficient and environmentally friendly, but the tiny gaps and the inner cavity of the workpiece are almost impossible to clean due to energy attenuation or inaccessibility, but the cleaning cost is high and there is color difference on the surface of the workpiece after cleaning

[0008] The above cleaning methods have a certain effect on the cleaning of the surface of the workpiece, and each has its own advantages and disadvantages, but the cleaning effect on the tiny holes, grooves, and gaps on the workpiece is not good, especially the gaps below the millimeter such as micron and nanometers. , The cleaning of the hole groove has no obvious effect
