Device for enhancing on-line quenching stability of extruded aluminum profile

Abstract

The invention relates to a device for enhancing on-line quenching stability of an extruded aluminum profile. The device comprises an automatic thermal-insulation unit arranged between a mold outlet and a quenching unit on an extruding machine. The automatic thermal-insulation unit is characterized by comprising a shell, a heater, a heat dissipation copper plate, a temperature measuring unit, a graphite cushion block and a thermal-insulation material, wherein the shell is in the shape of a rectangular solid; one side of the shell adjacent to the mold outlet is provided with a high-temperature-resistant felt curtain; a layer of the thermal-insulation material is uniformly distributed on the internal surface of the shell; the heater is uniformly distributed on the inner side of the thermal-insulation material; the inner side of the heater is provided with a layer of the heat dissipation copper plate; the side surface of the shell is provided with the temperature measuring unit; and the graphite cushion block is arranged on the bottom surface of the heat dissipation copper plate. By arranging the outlet thermal-insulation unit, the isothermal extrusion can be implemented only by one extruding machine, so that every profile produced by extrusion can be quenched at a constant temperature, thereby ensuring the properties of the profile and enhancing the yield of the profile.

Description

technical field [0001] The invention relates to a device for extruding aluminum profiles, in particular to a device for improving the quenching stability of extruded aluminum profiles, belonging to the field of aluminum profile extrusion production. Background technique [0002] At present, the extrusion production of industrial aluminum profiles mostly adopts the isothermal extrusion process. The isothermal extrusion is to realize the constant temperature of the aluminum profile at the mold outlet by adjusting the temperature of the aluminum rod, the no-load time of the extruder and the extrusion speed of the extruder to ensure quenching. The performance indicators of the finished aluminum profile are stable. Since the extruded aluminum profile equipment is not produced by one manufacturer, but by at least three manufacturers, and has high requirements for equipment performance and configuration, it is difficult for small and medium-sized enterprises to bear the investment ...
