Abstract
The utility model relates to an adjustable magnetic force near-critical resonance removes stress machine comprises work piece platform 1, suspending device 2, the source body and the controller 10 that shake. The current intensity is adjusted by adjusting the conduction angle of the controlled silicon half-wave rectification circuit through the potentiometer 8 of the controller 10 so as to adjust the amplitude and the frequency of the vibration source body, thereby enabling the workpiece to generate near-critical resonance and enabling the inner part of the workpiece to be rapidly and orderly arranged to eliminate the internal stress of the workpiece. The stress remover has the advantages of simple structure, convenient operation, strong capability of eliminating internal stress, high efficiency and 3-5 times of service life of a workpiece.
Description
The utility model relates to the mechanical product of a kind of elimination, the facility of complex structural member internal stress, be particularly related to a kind of utilize that magnetic force makes that product produces that nearly critical resonance eliminates internal stress remove the internal stress facility, also be applicable to and eliminate the fatigue stress that produces through the component inside after using
The product integral body or the part of powder metallurgy, forging, casting, machinofacture and complex construction all can produce internal stress, do not eliminate these internal stresss, will reduce the quality and the work-ing life of these products greatly.Usually all adopt heat treating method or aging process to eliminate internal stress and need consume a large amount of energy with heat treating method, the expense of Equipment for Heating Processing is also very high, and time spent efficacious prescriptions rule efficient is low; Particularly some product do not allow or be not suitable for adopting heat treating method also have a kind of adopt molecule that mechanical vibration method makes system member internal stress zone again ordered arrangement to eliminate its internal stress but this mechanical vibration de-stress machine just passes to the system member with the vibration source vibration, uncontrollable member and vibration source reach nearly critical resonance, therefore eliminate the poor effect of internal stress.
The purpose of this utility model provides the nearly critical resonance de-stress machine of a kind of FMAM magnetic force, by adjusting the vibrational frequency and the amplitude of vibration source body, make and wait to remove internal stress system member and the vibration source body reaches nearly critical resonance (85%-95%), eliminate internal stress to greatest extent to reach.
The utility model is design like this, it is by work stage 1, levitation device 2, controller 10, the vibration source body constitutes, its middle controller 10 is connected with the line bag 5 of the electro-magnet 4 of vibration source body, and the 220V civil power is carried out half-wave rectification provide the line bag 5 power supplys, electro-magnet produces the vibration hammer 7 of pulse-electromagnetic force driving vibration source body and makes double vibrations, thereby driving work stage 1 vibrates together, adjust the frequency and the amplitude of electro-magnet vibration by controller 10, make treating on work stage 1 and last the platform remove the internal stress workpiece and nearly critical resonance (85%-95%) takes place and reach and eliminate inner stress of work to greatest extent.Listen by directly perceived, feel, ear and can learn that both harmful resonance (i.e. resonance drift) takes place, slightly turn strength of current by controller this moment makes it neither away from resonance point, in near resonance point (85%-95%), work stage 1 is installed on the levitation device 2 only.
The utility model be in when, according to object resonance taking place its interior molecules can be rapidly the principle design of ordered arrangement again, eliminate the internal stress effect and can improve 3-5 doubly, man-made diamond producing apparatus cubic hydraulic press hard alloy top hammer for example, adopt the utility model to eliminate internal stress, can improve 3-5 times of work-ing life
Be described in further detail concrete structure of the present utility model below in conjunction with embodiment and accompanying drawing thereof
Accompanying drawing is the structural representation of the utility model embodiment, among the figure: 1, work stage 2, levitation device 3, support 4, " U " shape iron 5, line bag 6, armature 7, vibration hammer 8, vibration spring 9, spring strut 10, controller 11, multiturn potentiometer 12, keyswitch
As shown in the figure, present embodiment is made of work stage 1, levitation device 2, vibration source body, controller 10, and wherein work stage 1 is box body or platform; Levitation device 2 is a spring, and the one end is fixed, the other end carrying work stage 1; The vibration source body is made of electro-magnet and vibration hammer 7, and wherein electro-magnet is made up of line bag 5, " U " shape iron 4, " one " font armature 6." U " shape iron 4 and support 3, work stage 1 join together by bolt, and armature 6 joins together with vibration hammer 7 usefulness bolts; Spring strut 9 is fixed on the support 3, and vibration hammer 7 floats to be installed in and has on the spring strut 9 that vibrates spring 8; Controller 10 is made of silicon controlled rectifier half-wave rectification circuit, multiturn potentiometer 11, keyswitch 12; The line bag 5 of electro-magnet is connected with controller 10.
Can eliminate stress the as required weight classes of member of the utility model is not counted the nearly critical resonance de-stress machine of magnetic force of different size, makes the utility model seriation, to satisfy the needs of different user
