Embodiment 1

[0016] This embodiment provides a new process for processing finned radiator profiles, which includes the following steps: (1), put the raw aluminum block into the furnace and heat it to 670-700°C to liquefy the raw aluminum block, and then rely on the quality of the raw aluminum block Add 0.35%~0.4% slag remover to remove slag, then add corresponding proportion of other alloys to mix, finally filter and remove slag and pour liquefied aluminum into casting mold, after cooling treatment, aluminum alloy profile is obtained, aluminum alloy profile includes substrate and integrated (2) sawing the aluminum alloy profile to a specified length, preheating the extrusion die and the aluminum rod to between 320°C and 380°C, and then cutting the aluminum alloy profile And place the heated aluminum rod in the extrusion die, and use the extruder to carry out preliminary extrusion molding, the temperature is between 420°C and 460°C, and the extrusion speed is controlled at 8.5m per minute; (...

Embodiment 2

[0019] This implementation is further optimized on the basis of Embodiment 1, specifically:

[0020] Other alloys with corresponding ratios in step (1) include aluminum-silicon alloys, aluminum-copper alloys, aluminum-manganese alloys, aluminum-chromium alloys, aluminum-titanium alloys, aluminum-zirconium alloys, aluminum-strontium alloys and aluminum-scandium alloys.

Embodiment 3

[0022] This embodiment is further optimized on the basis of embodiment 1, specifically:

[0023] Step (1) Control the temperature of liquefied aluminum at 700-710°C before pouring into the mold, then add refining agent and purging and refining with inert gas, remove the scum on the surface of liquefied aluminum alloy during the refining process, and put The liquefied aluminum alloy is left to stand, and finally filtered to remove slag.

Abstract

The invention discloses a novel process for processing sections of a finned radiator, and relates to the technical field of radiator section processing, which aims to solve the technical problems of poor physical properties, poor mechanical properties and short service life of existing sections of the finned radiator. The novel process comprises the following steps of (1) treating aluminum blocksas raw materials so as to obtain aluminum alloy sections; (2) performing preliminary extrusion forming on a cooling plate on the aluminum alloy sections; (3) straightening and aging a workpiece whichis extruded in the previous step; (4) performing secondary extrusion forming on the cooling plate on the aluminum alloy sections; (5) straightening and aging the workpiece which is extruded in the previous step; (6) preparing before assembly; and (7) assembling, performing surface treatment, spraying, inspecting, packaging and warehousing. The novel process has the advantages of good mechanical properties, high production efficiency, low cost and long service life.

Description

technical field [0001] The invention relates to the technical field of radiator profile processing, and more specifically relates to a new finned radiator profile processing process. Background technique [0002] At present, metal profiles, especially aluminum profiles, are more and more widely used in industrial production and daily life. For example, door and window profiles, radiator profiles and frame profiles are mostly made of aluminum alloy profiles. With the gradual increase in the use of profiles, people put forward higher requirements for the structure and quality of profiles. In order to produce profiles with different structures and different qualities, it is necessary to use targeted production processes to produce corresponding profiles. A radiator is a device mainly used for heat dissipation of heat-generating parts in mechanical equipment or high-power electrical appliances. It is mostly made of aluminum alloy, brass or bronze. Aluminum alloy materials have ...
