Aluminum profile extrusion machines are divided into forward extrusion machines and reverse extrusion machines. Currently, most of them use forward extrusion machines. The scientific principle is the principle of hydraulic press. The structure of the extruder needs to be analyzed: the extruder is generally divided into three parts: the main cylinder, the middle plate (extrusion barrel), and the extrusion rod.
How to Improve the Precision of Aluminum Profile Extruder
The master cylinder is a hydraulic device. The gear oil transmits pressure to the small piston according to the big piston, pushes the extrusion rod, pushes the heated aluminum ingot to the extrusion barrel, and after reaching the exhaust pressure, the extrusion barrel reverses to exhaust, and then moves forward to connect with the inner cavity of the mold. After reaching the discharge pressure, the extrusion rod moves forward at the same time to send the aluminum in the extrusion barrel to the mold separation hole, and the aluminum alloy slowly flows out to form according to the mold.
The longitudinal and transverse flatness of the base slide rail shall not exceed 0.05/1000; After installation or maintenance of the aluminum profile extrusion machine, attention should be paid to the flatness of the two slide rails: the total length of the slide rails should not be detected or adjusted to achieve relevant accuracy of 0 or above. 1mm specifications or design requirements.
How to improve the speed of aluminum profile extrusion machines? Adjusting the tonnage of the extruder, the complexity of the mold cross-section shape, and the heating temperature of the aluminum ingot appropriately can improve the speed to a certain extent.
