Combined reinforced shot blasting device and method

Abstract

The invention belongs to the field of gear manufacturing, and discloses a combined reinforced shot blasting device and method. The combined reinforced shot blasting device comprises a working rotary table, a plurality of shot generation systems, a plurality of spray gun systems and a control system, wherein the shot generation systems and the spray gun systems are connected in a one-to-one correspondence mode; the working rotary table is used for supporting and driving a part to be subjected to shot blasting to rotate; the plurality of spray gun systems are arranged above the working rotary table and used for shot blasting of the part to be subjected to shot blasting; and the control system is connected to the working rotary table, the plurality of shot generation systems and the plurality of spray gun systems and used for controlling rotation of the working rotary table, the shot pressure and the shot flow of each shot generation system and the distance between each spray gun system and the part to be subjected to shot blasting. Strengthened shot blasting of different composite process parameters is achieved on the same equipment, so that the residual stress and depth of a surface and a sub-surface are increased, the surface roughness is reduced, meanwhile, independent control over different combined processes is achieved, the equipment failure rate is reduced, and consumption of quick-wear parts is reduced.

Description

technical field [0001] The invention belongs to the field of gear manufacturing and relates to a combined strengthening shot peening device and method. Background technique [0002] Strengthening shot peening is a very effective way to improve the fatigue life of gears, and it is widely used at home and abroad. At present, domestic and foreign intensified shot peening devices generally use a flip-type turntable or a step-by-step turntable plus a small planetary turntable, equipped with a set of shot generation system, several shot valves and several spray guns. Through the control system, multiple shot valves are simultaneously controlled. Under the same shot peening pressure, a certain size of shot is sprayed onto the surface of the part to achieve surface strengthening of the part, and even the flow and pressure are adjusted to strengthen on one device multiple times or on multiple devices Shot peening, to achieve a certain coverage, residual stress and roughness on the s...
