Extrusion rod of aluminum profile extrusion press machine plant line

Aluminum extrusion rod extrusion machine, maintenance knowledge more often we mentioned is not mentioned as extrusion rod, actually this is a important components of the extruding machine, the main function is used to transfer pressure, actually not easy also would fail, so fewer mentioned, but we still have to time to learn the knowledge, convenient to use in the future.

First, why is the rod of the aluminum profile extrusion press machine plant line always broken?

The extrusion rod of aluminum profile extrusion press machine plant line, its main function is used to transfer pressure, if the central pressure rod is often broken, both cause economic losses, while affecting production, delayed delivery, extrusion machine central rod fracture caused by equipment operation rate can only reach about 85%, the industry is so. At present, we are trying to solve this problem in many ways, and strive for the equipment operation rate of more than 98%. Therefore, in the extrusion tool of the aluminum profile extrusion press machine plant line, the extrusion rod is also a very important part. The main reason for the broken rod of the aluminum profile extrusion press machine plant line is that the center is not connected well when the installation and debugging is done. Then how to install and debug is correct?

Two, how to install the extrusion rod of the aluminum profile extrusion press machine plant line is appropriate?

The outer diameter of the extrusion rod is determined according to the inner diameter of the extrusion cylinder. Horizontal extruder extrusion rod diameter general ratio. The inner diameter of the cylinder is 4 ~ 10mm smaller. The end of extrusion rod may be upset due to plastic deformation when working at high temperature. Therefore, the diameter of the end of the solid extrusion rod should be smaller, and the inner diameter of the end of the hollow extrusion rod should be larger, so as not to put in when the large perforation needle is changed after deformation. To avoid stress concentration, the transition part of the root of the extrusion rod should be tapered and have a large rounded corner, with a radius R≥100mm. If the arc is too small or the root is not well matched with the diameter of the rod body, the extrusion rod will break.
