What are the requirements for printing machinery assembly?

In normal work, problems of disassembly and equipment of printing machinery due to plant renovation, site relocation, equipment replacement or maintenance are often encountered. If these are not handled well, it will seriously affect normal production and cause economic losses.

For parts that are often in need of repair and replacement, the quality inspection should be carried out carefully before assembly, and the important part should be tested.

In order for the assembly work to be carried out in an orderly manner, some of the assemblies should be assembled in advance for smooth assembly. Parts must be cleaned before assembly to prevent oily dirt from getting into the mechanical parts.

Assembly accuracy is a guarantee for improving assembly quality and mechanical repair quality. If only high-precision machining is performed but there is no high-precision assembly, there will be no high-quality mechanical repair, so attention should be paid to assembly accuracy. Assembly accuracy includes fit accuracy and dimensional accuracy. The precision of the fit is the internal wear of the machine that destroys the normal coordination work. The purpose of the repair is to restore the normal fit relationship of the parts. In order to ensure the accuracy of the fit, we can use the matching method, the repair method and the adjustment method.

In printing machinery, some fittings require high precision, such as a lithographic printing press. When the machining accuracy of the fittings cannot meet the requirements, it must be matched. The most important thing is the matching of the gap. The repairing method is a common measure in mechanical assembly. It is a small amount of simple processing of the parts before assembly or assembly. For example, the machining method of the vehicle is to improve the precision of the parts. It is also a method often used in assembly, which effectively improves the assembly precision of the printing machine by using the method of increasing or decreasing the gasket and adjusting the screw.
