Description
Technical field
The utility model relates to a kind of mechanical device, relates in particular to a kind of mechanical device that can eliminate welding residual stress.
Background technology
Hardware generally adopts the method for molten solder when welding, in the filling process of metal, leave reinforcement, pit and various weld defect at joint area, causes serious stress concentration, also produces certain welding residual stress simultaneously.The size of residual stress is the important indicator that influences the Welding Structure performance, and in most cases, residual tension is disadvantageous to welded fatigue strength.The general normal crack initiation of its fatigue crack is in welding toe; Very easily cause fatigue crack occurring like the welding position of large welded structures spares such as offshore oil upper brace, bridge, carriage frame, boats and ships; Some taking place lose great accident, brings some to seriously influence for people's personal safety, work, life, economic dispatch aspect.Therefore, how effectively to eliminate the difficult problem that welding residual stress becomes people's tackling key problem.Usually people adopt heat aging, oscillating aging, hammering method, TIG remelting, shot-peening method, explosion method to wait and eliminate welding residual stress, but all have such or such shortcoming.Recently people adopt magnetostriction type ultrasonic impact device to come the butt welded seam residual stress to handle, to eliminate welding residual stress.But because the electromechanical conversion efficiency of magnetostriction type ultrasonic impact device only reaches about 30%, loss is bigger; Ultrasonic impact gun is easy to heating and needs water, wet goods liquid to cool off etc. in the work engineering, and cost is very high; Simultaneously, the impact gun volume and weight is all bigger, is unfavorable for operation and use, thereby in a few thing occasion, is unfavorable for promoting and using.
Summary of the invention
The purpose of the utility model is that the impact gun noise is big, efficient is low in order to solve, unstable properties, problem that energy consumption is high, and a kind of ultrasonic impact gun of eliminating welding residual stress is provided.
The technical scheme that the utility model solves its technical problem can be:
A kind of ultrasonic impact gun of eliminating welding residual stress mainly is made up of handle frame, fan, wafer energy transducer, screw mandrel, horn, nylon spacer, impact needle guard, striker pin, nut, shell and digital power control cabinet, and its shell is a bullet shaped; Top, outside is provided with screw thread, and the bottom is provided with circular hole, and inside is cavity; Cavity top is provided with boss; Shell upper connects impacts needle guard, and striker pin puts circular hole is set, and impacts needle guard lower case outer setting nut; Outer casing underpart connects handle frame; Enclosure sets gradually fan, wafer energy transducer, horn and striker pin, and striker pin leans out through the circular hole that striker pin puts setting, and screw mandrel is arranged in the screwed hole of wafer energy transducer top and the setting of horn lower central; Nylon spacer is arranged on below the boss that enclosure is provided with, and wafer energy transducer, fan and digital power control cabinet are electrically connected.
The technical scheme that the utility model solves its technical problem also can be:
Described a kind of ultrasonic impact gun of eliminating welding residual stress, its described impact needle guard is a bottle cap shape, and the bottle cap top is provided with circular hole, and described horn is bullet-headed, and the sub warhead middle part is provided with step, and bottom centre is provided with screwed hole.
The beneficial effect of the utility model is:
1, the utility model impact gun has the conversion efficiency height, long service life, and treatment process is simple, and effect stability is reliable, and one-time continuous work maximum duration can reach 24 hours.
2, the utility model impact gun has easy to use flexible; Do not receive the restriction in workpiece material, shape, structure, steel plate thickness, weight, place; Be applicable to the ultralow weld seam of building site weld seam, superelevation of large-sized structural parts, the processing that eliminates stress of REPAIR WELDING weld seam; Can eliminate the residual stress effective thickness is 3-5mm, and eliminating residual stress is 100%.
3, the utlity model has reasonable in design, simple in structure, be easy to process, easy to use, energy-conserving and environment-protective, noise are minimum, the characteristics of high efficiency.
