Problems solved by technology

[0002] It is well known that the maximum exit speed that metals can achieve in extrusion deformation has always been the main goal pursued by the extrusion process. The established goals are stipulated. Due to the various cross-sections, complex shapes, and large extrusion ratio ranges of the 6063 series alloy extrusion profiles, it is difficult to control the maximum exit speed and optimize the parameters of the extrusion process, thus affecting the efficiency and surface finish of the profiles. brightness

Embodiment Construction

[0011] In order to further understand the characteristics and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are given below with reference to the accompanying drawings.

[0012] During the extrusion production process, the online parameters should be controlled at:

[0013] Heating temperature To of round aluminum ingot before extrusion = 375°C-520°C, extrusion outlet temperature Te = 490°C-540°C, moving speed of extruder plunger Vs = 3-10mm / s, depending on profile extrusion ratio and extrusion The pressure defines the rp value, rp=Pmax-P / Pmax×100%;

[0014] The control method is as follows: use a two-color infrared thermometer and connect it to the industrial microcomputer control system, and implement non-contact infrared temperature measurement on the instantaneous temperature of the profile outlet. The display shows that the extrusion outlet temperature Te=490°C-540°C, because the profile outlet temperature sh...
