After the whole machine of the offset printing machine is disassembled, it can be disassembled into four parts, namely the paper feeder, the ink distribution part, the printing part and the delivery part. The offset printing machine should pay attention to the following aspects during the disassembly and disassembly process:
Get familiar with the machine
At present, there are many types and models of offset printing machines. Before disassembling, it is necessary to fully understand the knots and working principles of various parts of the machine, otherwise the parts will be damaged. For some structures that are difficult to understand at a time, you should first consult the instruction manual of the relevant data and device.
2. Disassemble as needed
For offset presses that need to be repaired, the parts that need to be disassembled should be correctly judged. Some institutions do not need to disassemble when they are in good condition. This is because the fittings tend to reduce the matching precision after one disassembly and assembly. When the machine is running, it must: When the wrench is turned, the wear of the parts is accelerated.
3. Tool selection
The tools used to disassemble the offset press should be compatible with the parts being disassembled. For example, to remove the threaded connector, you should use a suitable wrench, avoid hammering, shoveling, and knocking, causing damage to parts, and you can't use the hammer, pliers, hand, etc. instead of the hammer.
4. Mark well
Before disassembling the offset press, except for the parts with positioning screws, pins and key positioning, the positions of the parts that are not positioned are marked before disassembly for easy installation. For example, the circumferential position relative to the circumferential position of the drum gear and the hub is marked, and the mutual engagement positions of the drum gears are also marked before disassembly, so that the matching relationship between the E and the E is ensured during installation. The position of the mutual edge is the same as before the disassembly, avoiding rework.
5. Classified custody
Disassembled parts should be kept in separate categories to avoid confusion. Generally, the number of parts of small parts is about 50:, and these parts should be cleaned and stored separately after disassembly. The fastening, transmission parts, operating parts and other parts that are connected with the wallboard should be placed on both sides of the offset printing machine, and the transmission side and the operating side should be separately stacked.
6. Disassemble in order
The correct offsetting machine order should be: first up and down, first outside and then inside, first remove the above parts, 'removing the following parts; first remove the exposed parts, then remove the parts inside. Parts should also be placed in the order of disassembly.
