Problems solved by technology
Burrs on the parting surface of castings, ingates and riser neck residues are unavoidable structures in castings, especially in special-shaped castings. These structures are not needed by customers and must be cleaned and ground. In the past, castings were cleaned completely. Relying on manual grinding, the work efficiency is extremely low, the working environment is harsh, the labor cost is high and the labor force is strong
In the process of manual cleaning and grinding of castings, there are many parts of diesel engine cylinder head castings that need to be cleaned. The structure is thick and large, so it is very difficult to clean and grind. The daily quota of workers is very low; there is no strict standard for cleaning and grinding. The scale has a lot to do with it, and customer complaints due to the quality of the castings often occur; the consumption of the grinder, polishing disc, and grinding head required for grinding is quite serious; the structure of the cylinder head casting of the diesel engine is complex, and there are many parts that need to be cleaned. Workers need to keep moving castings and changing angles to clean them up; the fine dust generated by cleaning and grinding spreads throughout the workshop, seriously affecting the health of workers; more importantly, the safety of workers cannot be guaranteed

Embodiment
[0038] A production process for cleaning and transporting cylinder head castings of an environment-friendly vehicle diesel engine, comprising the following steps:
[0039] Grinding: The ground and vibrated cylinder head blank is automatically conveyed to the cleaning conveying roller table by the roller table through the turntable;
[0040] Unloading: conveyed by the roller table to the unloading station of the single-girder crane for grinding castings at the corner of the front span, and temporarily unloading when there is a problem with the quality of the grinding castings;
[0041] Cleaning: transported by the roller table to 10 stations on each of the two roller tables outside the cleaning compartment, and manually clean the cylinder head on the roller table;
[0042] Welding repair: After the cylinder head blank is cleaned online, it is transferred by the conveyor roller table to the single-beam crane loading and unloading station for welding repair parts; the cylinder he...

Abstract
The invention discloses an environment-friendly automobile diesel engine cover casting cleaning and conveying production process. The process comprises the following steps of grinding, blanking, cleaning, repair welding, shot blasting, shot pouring, soot blowing and inspection. According to the process, engine cover casting blanks with ground planes are conveyed to a manual cleaning separation chamber, a manipulator shot blasting machine, a casting blowing chamber, casting inspection, casting coating and the other working procedures in sequence. Safe and reliable operation of a casting cleaning and conveying system can be ensured.
Description
technical field [0001] The invention belongs to the field of cleaning and conveying of castings, and in particular relates to a production process for cleaning and conveying cylinder head castings of environment-friendly vehicle diesel engines. Background technique [0002] After the casting is poured, it enters the cleaning process of the casting after unpacking, sand shakeout and shot blasting. Burrs on the parting surface of castings, ingates and riser neck residues are unavoidable structures in castings, especially in special-shaped castings. These structures are not needed by customers and must be cleaned and ground. In the past, castings were cleaned completely. Relying on manual grinding, the work efficiency is extremely low, the working environment is harsh, the labor cost is high and the labor force is strong. In the process of manual cleaning and grinding of castings, there are many parts of diesel engine cylinder head castings that need to be cleaned. The structu...
