How to improve the precision of aluminum extrusion press

Aluminum profile extrusion presses are divided into two types: forward extrusion and reverse extrusion. Now most of them are forward extrusion presses. The scientific principle is the hydraulic press principle. It is necessary to analyze the structure of the extruder: we usually The extruder is divided into three parts: the main cylinder, the middle plate (extrusion barrel), and the extrusion rod. The main cylinder is a hydraulic device. The hydraulic oil passes through the large piston to the small piston, pushing the kneading rod, and pushing the heated aluminum.com/aluminium-curtain-rod.html' target='_blank'>aluminum rod into the extrusion barrel. After reaching the exhaust pressure, the extrusion barrel retreats and exhausts, and then travels with the mold After the cavities are joined and the output pressure is reached, the extrusion rod moves simultaneously to send the aluminum in the extrusion barrel into the mold shunt hole, and the aluminum alloy gradually flows out through the mold to form. The vertical and horizontal horizontality of the guide rail of the machine base should not exceed 0.05/1000; after the aluminum extrusion press is installed or large or medium repaired, the parallelism of the two guide rails must be paid attention to: the device accuracy inspection and adjustment should not be carried out on the full length of the guide rail , To make it reach the relevant accuracy beyond the 0.1mm degree specification or planning requirements.  How to increase the speed of the aluminum extrusion press when there is accuracy? Depending on the tonnage of the extruder, the degree of messiness of the cross-sectional shape of the die, the heating temperature of the aluminum rod and other factors, make appropriate adjustments, so that the speed can be increased. ————The article comes from the Internet.
