Embodiment 1

[0067] An air rudder torsion bar processing process, the production process of the torsion bar is: mechanical processing->heat treatment->heating and loading->magnetic particle inspection->wire cutting->mechanical processing->surface treatment->angle inspection->endurance test -> Angle inspection -> Delivery and storage; the working environment temperature of the processing is not lower than 25°C. In the heating and loading step, the torsion bar is twisted 90 degrees on the tooling and then fixed. The temperature of the workpiece entering the furnace must not exceed 30°C. Heating up; keep it at 110-120°C for 2-3 hours and then do not release it immediately. After the furnace drops to 25-30°C, unload the workpiece after the furnace is released to restore the torsion bar to its original shape, and then re-twist the torsion bar by 90 degrees to install and fix it. , enter the furnace and heat up to 110-120 ℃ for 1.5-2 hours, the product is not released immediately, after the tempe...

Abstract

The invention relates to an air vane torsion lever processing technology. The torsion lever manufacture flow comprises mechanical processing, thermal processing, heating and loading, magnetic powder inspection, wire-electrode cutting, mechanical processing, surface processing, angle test, duration running, angle test and delivery and warehousing. The invention is characterized in that the processing work environment temperature is not lower than 25 degrees centigrade, as for the heating and loading procedure, a torsion lever is twisted for 90 degrees on a frock and then is fixed, the entry temperature of a workpiece is not more than 30 degrees centigrade and is increased along with the temperature of a furnace, after being kept for 2 to 3 hours at 110 to 120 degrees centigrade, the temperature of the workpiece is reduced to 25 to 30 degrees centigrade along with the furnace temperature, the workpiece is discharged and is unloaded so that the torsion lever is restored, the torsion lever is twisted for 90 degrees again, installed and fixed, the temperature of the torsion lever rises to 110 to 120 degrees centigrade along with the furnace temperature, kept for 1.5 to 2 hours and is reduced to 25 to 30 degrees centigrade along with the furnace temperature before being discharged and unloaded to restore the torsion lever.

Description

technical field [0001] The invention relates to mechanical processing science, and in particular provides an air rudder torsion bar processing technology. Background technique [0002] The air rudder is the key device to control the flight according to the guidance instruction. Among them, the air rudder torsion bar is an extremely important part to ensure that the air rudder is unfolded and locked after it is released from the cylinder. Its performance will directly affect whether the air rudder can work normally. Air rudder torsion bar in the development stage and the initial stage of mass production, the qualified rate has been relatively low, about 40%, which seriously affected the production progress and delivery nodes of the product, not only increased the production cost of the manufacturer, but also failed to meet the reliability of the product quality sexual pursuit. In this regard, in order to ensure product quality in the acceptance of the air rudder torsion ba...
