Troubleshooting of Cylinder in Pneumatic Punching Machine
When the cylinder on the pneumatic punching machine malfunctions, it can be coated or sprayed on the joint surface of the pneumatic punching machine cylinder. When there is a large area of steam leakage on the joint surface of the pneumatic punch cylinder, with a gap of about 0.50mm, in order to reduce the workload of grinding and scraping, the coating process can be used.
Using a pneumatic punch cylinder as the anode and a coating tool as the cathode, repeatedly apply electrolytic solution on the joint surface of the cylinder. The thickness of the coating should be determined according to the size of the gap between the joint surfaces of the cylinder, and the type of coating should be determined according to the material of the cylinder and the scraping process.
Spraying is a method of using a specialized high-temperature flame gun to heat metal powder to melt or reach a plastic state, and then spraying it onto the surface of a treated cylinder to form a coating with the required properties. Its characteristics are simple equipment, easy operation, and firm coating. After spraying, the cylinder temperature is only 70 ℃ -80 ℃, which will not cause deformation of the cylinder. Moreover, a heat-resistant, wear-resistant, and corrosion-resistant coating can be obtained.
It should be noted that the cylinder surface should be polished, degreased, and roughened before coating and spraying. After coating and spraying, the coating should be scraped to ensure the tightness of the joint surface of the pneumatic press.
