Abstract
A superharmonic resonance type vibration aging device for workpieces with high natural frequency comprises a vibration exciter, a vibration exciting block, an adjustable damper and an adjustable nonlinear spring, wherein the vibration exciter is connected with the vibration exciting block, and the adjustable damper, the adjustable nonlinear spring and the vibration exciting block form a nonlinear vibration system. The vibration exciting block generates superharmonic resonance with the vibration exciting frequency far higher than the original vibration exciting frequency of the vibration exciter by utilizing the vibration exciter acting on the nonlinear vibration system, and then acts on the workpieces through the superharmonic resonance frequency approaching to the natural frequency of the high-rigidity workpieces, so that main resonance and corresponding dynamic stress can be generated to reduce the residual stress of the workpieces. The superharmonic resonance type vibration aging device can solve the difficult problem that the vibration aging treatment can not be conducted on the high-rigidity workpieces.
Description
Technical field
The utility model relates to field of machining, particularly a kind of high natural frequency workpiece ultraharmonic resonance formula vibration ageing device.
Background technology
Workpiece may produce unrelieved stress in the cold and hot working process, eliminating unrelieved stress is very important work.The method of subduing unrelieved stress commonly used has natural aging, thermal life, oscillating aging.Natural aging is long because of its production cycle, and occupied ground is big, and manageability can not in time not found the defective in the workpiece, is eliminated gradually.The thermal life method is still generally adopted by factory at present, but thermal life labour intensity is big, and is seriously polluted.With respect to thermal life, oscillating aging can be saved the energy and expense, particularly can save the investment of building large-scale anneal kiln.
At present, vibration aging technology is adopted by many enterprises.And existing vibrator is subjected to the restriction of motor speed and eccentric mechanism maximum speed of revolution, and its excited frequency is all less than 200Hz, so vibration ageing device just can not use during in the face of the workpiece of high natural frequencies such as engineering topping roll, machine pillar, lathe crossbeam.The resonance problem that how to solve the high natural frequency workpiece is the unsolved in decades thorny problem of vibration aging technology development, has seriously restricted the application of vibration aging technology.
Summary of the invention
The purpose of this utility model provides a kind of high natural frequency workpiece with ultraharmonic resonance formula vibration ageing device, solves existing vibrator because its excited frequency is low and can't carry out high rigidity workpiece the difficult problem of oscillating aging.
The utility model achieves the above object by the following technical programs: the high natural frequency workpiece comprises vibrator, exciting piece, adjustable damping and adjustable non-linear spring with ultraharmonic resonance formula vibration ageing device.
Vibrator is connected with the exciting piece, and adjustable damping, adjustable non-linear spring and exciting piece are formed non-linear system, and vibrator acts on non-linear vibrating system can make the ultraharmonic resonance of exciting piece generation far above the former excited frequency of vibrator.
Make the ultraharmonic resonance of exciting piece generation by the parameter of adjusting vibrator frequency, adjustable damping and adjustable non-linear spring far above the former excited frequency of vibrator, the exciting piece again with near the ultraharmonic resonance frequency effect of high rigidity workpiece natural frequency in workpiece, make it produce primary resonance and corresponding dynamic stress to subdue the unrelieved stress of workpiece.
Outstanding advantage of the present utility model is:
1, adopt ultraharmonic resonance formula oscillating aging mode, the exciting piece can produce the vibrational frequency far above the former excited frequency of vibrator, and the vibrational frequency that can be used for the oscillating aging of high natural frequency workpiece and exciting piece is adjustable within the specific limits, and it is applied widely.
2, this apparatus structure is simply compact.
Description of drawings
Fig. 1 is a high natural frequency workpiece described in the utility model ultraharmonic resonance formula vibration ageing device structural representation.
Fig. 2 is the work synoptic diagram of high natural frequency workpiece described in the utility model with ultraharmonic resonance formula vibration ageing device.
Embodiment
Below by drawings and Examples the technical solution of the utility model is described further.
High natural frequency workpiece described in the utility model comprises adjustable damping 1, adjustable non-linear spring 2, exciting piece 3 and vibrator 4 with ultraharmonic resonance formula vibration ageing device.
Contrast Fig. 1, exciting piece 3 is connected with vibrator 4, and adjustable damping 1, adjustable non-linear spring 2 and exciting piece 3 are formed non-linear vibrating system.
Contrast Fig. 2, the incentive action that the workpiece 5 that supports on 6 is subjected to exciting piece 3 that is set forth in.Described vibrator 4 acts on exciting piece 3 and makes the ultraharmonic resonance of its generation far above the former excited frequency of vibrator, exciting piece 3 again with near the ultraharmonic resonance frequency effect of high rigidity workpiece natural frequency in workpiece 5, make it produce primary resonance and corresponding dynamic stress to subdue the unrelieved stress of workpiece 5.
The parameter of excited frequency, adjustable damping 1 and adjustable non-linear spring 2 by changing vibrator 4 makes exciting piece 3 have different excited frequencies, thereby can satisfy the oscillating aging requirement of different-stiffness workpiece.
