Production technology for aluminum alloy wire harness installing support for trailer

Abstract

The invention belongs to the technical field of aluminum alloy machining, and relates to a production technology for an aluminum alloy wire harness installing support for a trailer. A 6061 aluminum alloy cast ingot comprises, by mass percent, 0.4%-0.8% of Si, smaller than or equal to 0.7% of Fe, 0.15%-0.4% of Cu, smaller than or equal to 0.15% of Mn, 0.08%-0.12% of Mg, 0.04%-0.35% of Cr, smaller than or equal to 0.25% of Zn, smaller than or equal to 0.15% of Ti, smaller than or equal to 0.05% of single impurities, smaller than or equal to 0.15% of all impurities, and the balance Al. The aluminum alloy cast ingot with the formula is cast, homogenizing treatment is conducted, a 1250 T extruder is used for extrusion, the extrusion temperature ranges from 500 DEG C to 520 DEG C, the extrusionspeed ranges from 7 m / min to 9 m / min, the temperature of an aluminum alloy sectional material before quenching is larger than or equal to 510 DEG C, and the quenching manner is water cooling; the temperature of the aluminum alloy sectional material after quenching is smaller than or equal to 50 DEG C, the stretch rate is controlled to range from 0.5% to 1.0%, the extruded sectional material is cutto the required size, aging is conducted within 12H, the aging system is 175 DEG C x (7-9) H, stretch bending forming is conducted after aging, the produced wire harness installing support is high instrength, the structure is simplified, space is saved, stability is good, and safety performance is high; and the wire harness installing support does not need to be welded, the integral structure ismore light and attractive, and rapid mounting and dismounting of the installing support are achieved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and relates to a production process of an aluminum alloy wiring harness mounting bracket for a trailer. Background technique [0002] The trailer head and the car body transmit signals through the wire harness to realize the control of the car head to the car body. The wire harness connector is installed on the wire harness board to achieve a stable connection and a regular and orderly connection. The existing wiring harness boards vary from manufacturer to manufacturer. Most of them are welded on the car body with steel, which is bulky, difficult to assemble and disassemble, and easy to corrode, which affects the stability and service life of the wiring harness. [0003] The U-shaped aluminum alloy wiring harness installation bracket produced by extrusion and bending technology is used to fix the wiring harness plate on the bracket to realize the function of fixing the wiring h...
