Multi-hole multi-channel auto part washing system

Abstract

The invention discloses a multi-hole multi-channel auto part washing system, and belongs to the technical field of part washing. According to the machining process, the multi-hole multi-channel auto part washing system sequentially comprises high pressure washing equipment, spraying wind shearing equipment, hot air preheating equipment and vacuum drying equipment. According to the vacuum drying equipment, vacuum low-pressure sudden boiling is used for achieving quick drying of the parts, and a vacuum drying groove is formed inside the vacuum drying equipment and communicates with a high-pressure thorough blowing device; and by means of the high-pressure thorough blowing device, a hydrocarbon washing agent and high pressure air can be blown out, the sprayed out high-pressure hydrocarbon washing agent is used for washing the multi-hole multi-channel auto part surfaces and internal multi-holes and multi-channels, and then the high pressure air is used for thoroughtly blowing internal impurities and multi-hole multi-channel remaining agents.

Description

technical field [0001] The invention relates to the technical field of parts cleaning, in particular to a porous and multi-channel auto parts cleaning system. Background technique [0002] At present, the cleaning of parts is mostly carried out with hydrocarbon cleaning fluid. On the one hand, it has good solubility, and on the other hand, it is environmentally friendly and recyclable. The combination of ultrasonic and vacuum cleaning can greatly improve the cleaning efficiency, but carbon The hydrogen cleaning fluid has a low ignition point and the surrounding environment of the production workshop is complex, so the requirements for the sealing of the cleaning environment are relatively strict. [0003] Due to the porous and multi-channel structure of most auto parts, it is difficult to remove internal impurities and burrs by ultrasonic cleaning. Most auto parts must be cleaned by high pressure cleaning, especially the transmission case or Valve plates and other parts. M...

Problems solved by technology

Moreover, the transmission casing or valve plate cleaning system generally includes several steps such as high-pressure cleaning, spray wind cutting, hot air preheating, vacuum drying, and cooling and cooling. Due to the porous and multi-channel structure, only vacuum drying is used to remove the internal water. The efficiency is very low, so hot air preheating must be used, and hot air preheating is easy to contact with open flames to ignite and detonate hydrocarbon cleaning fluid, so the previous process cannot use hydrocarbon cleaning fluid to effectively remove surface oil, and often the workshop will save The use process of hydrocarbon cleaning fluid

[0004] Moreover, there is still a drawback in the traditional system at present, that is, there are still some water stains in the porous or multi-channel after vacuum drying. In order to solve the above problems, on the one hand, the hot air preheating time is prolonged, and on the other hand, the vacuum drying time is increased. According to statistics, if the product is qualified, it generally takes at least 10 minutes; with continuous improvement, a hydrocarbon cleaning liquid high-pressure cleaning and blowing device is added between the hot air preheating and vacuum drying devices, but despite the hot air preheating time and vacuum drying Due to the addition of the time for high-pressure cleaning and blowing of hydrocarbon cleaning fluid, the overall production efficiency has not improved, only the surface quality of the product has been improved, and because the newly added high-pressure cleaning and blowing of hydrocarbon cleaning fluid The safety requirements of the device are relatively high, and the cost of the equipment itself is relatively high, so the actual application effect is not good.
