The working principle of pneumatic pressure riveting machine and hydraulic pressure riveting machine is basically the same, it is through the air pump or oil pump pressure gas (or oil) forced into the pipeline, forcing the executive element action. The difference is that the medium used is different: one is air, the other is hydraulic oil. But it is because of the different medium, caused by the two work performance is different, there are mainly the following points: 1, pneumatic environmental protection, clean, and hydraulic oil more. 2, work, pneumatic action fast, fast response, but also large vibration; Hydraulic action is slow but smooth. 3, hydraulic can produce large tonnage of equipment, and pneumatic is limited at this point. 4. In terms of construction and maintenance, hydraulic pressure is more complicated than pneumatic pressure, and of course the manufacturing cost is higher. 5, in speed regulation, hydraulic is easier to do than pneumatic.

Matching problem of intake air pressure and set riveting force of pneumatic riveting machine

Pneumatic riveting machine is driven by compressed air, pressure riveting machine air pressure is proportional to its output pressure. So the user in the use of pneumatic riveting machine to have stable output pressure should pay attention to the intake pressure and output pressure matching. When the riveting machine returns automatically after finishing the riveting work, the intelligent pressure controller will display the current output pressure. When this value is greater than the intelligent pressure controller set value 15, please lower the intake pressure. When this number is less than the pressure value set by the intelligent pressure controller, the machine cannot automatically return, please increase the pressure. Repeat it a few times to get a matching output force.

Hydraulic riveting machine performance

High efficiency and energy saving: because only in the short time of the rivets into the workpiece to send "great strength", and usually only to pneumatic pressure to promote, so the energy consumption is extremely economic, compared with the full hydraulic or full cylinder, the energy saving effect can reach more than 90%. The operation is simple: because of the intelligent control, there is no need to adjust the mold in the process of riveting, and the digital control mode makes you only need to press a few buttons to achieve the control of the output force. Surface level off: because it is to use pressure and not stroke for riveting control, so the workpiece surface of riveting is quite level off, the product with high surface requirements can be exempted from grinding, scraping ash of labor, also won't leave the indentation of the mold on the softer base material such as aluminum plate. Soft in place: in the empty stroke, the upper die is driven by compressed air and quickly touches the workpiece. In this process, the running force of the upper die is very small, so there is no impact and no noise on the lower die, and it is easy to achieve "soft in place".

Smart power works: with the aid of digital control system for final strength after simple setting to achieve automatic control, so the thickness of a sheet metal workpiece, rivet head whether rules, hard and soft mould distance is adjustable up and down reasonable all need not too much to consider, you only need to set the output force of tonnage in a certain range, and then rivet is automatic and accurate pressure flush with the workpiece.

Taicang rivetless connection aircraft daily maintenance

1, do not process more than the nominal capacity of the workpiece.

2. Don't work under high pressure for a long time.

3, the length of the riveting head should not exceed the specified value.

4. Stop for maintenance immediately in case of any abnormality, and direct fault elimination.

5. The guide rail of the equipment should be coated with butter once a month to make it lubricated and rust-proof.

6, the assembly and disassembly of the riveting head should be light, especially in the disassembly of the riveting head do not use brute force to pull out, should rotate the riveting head and pull out slowly downward force. If the rivet seat is pulled out of the normal position, the position of the rivet head will appear obvious deviation after the installation of the rivet head. At this time, the red safety cover should be removed and the rivet seat can be used only after it is installed in place, otherwise the machine is easily damaged.

7, the use of riveting head in the processing of some materials will appear slight bonding phenomenon, in order to ensure the quality of riveting, should be scheduled to clean the riveting head, prevent metal bonding thicker. The riveting head is fixed to the chuck of the lathe for cleaning, and then polished with sandpaper.

8. The equipment shall be maintained daily every two weeks. The main maintenance items are as follows.
