Abstract
The invention relates to an ultraharmonic-resonance vibratory stress relief device for a high-natural-frequency workpiece, which comprises a vibration exciter, a vibration excitation block, an adjustable damping and an adjustable nonlinear spring, wherein the vibration exciter is connected with the vibration excitation block, and the adjustable damping, adjustable nonlinear spring and vibration excitation block constitute a nonlinear vibration system. The vibration exciter acts on the nonlinear vibration system, so that the nonlinear vibration system generates ultraharmonic resonance at a frequency which is far higher than the original exciting frequency of the vibration exciter; and the vibration excitation block acts on the workpiece at an ultraharmonic resonance frequency approximate to the natural frequency of the high-rigidity workpiece, so that the workpiece generates main resonance and corresponding dynamic stress to reduce the residual stress of the workpiece. The invention can solve the problem that the high-rigidity workpiece can not be subjected to vibratory stress relief treatment.
Description
Technical field
The present invention relates to field of machining, particularly a kind of high natural frequency workpiece is with 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 seasoning, thermal life, oscillating aging.Seasoning 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 receives 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 invention is to provide a kind of high natural frequency workpiece with ultraharmonic resonance formula vibration ageing device, solve existing vibrator and can't carry out the difficult problem of oscillating aging to high rigidity workpiece because its excited frequency is low.
The present invention achieves the above object through following technical scheme: 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 exciting piece produce the ultraharmonic resonance far above the former excited frequency of vibrator.
Parameter through adjustment vibrator frequency, adjustable damping and adjustable non-linear spring makes the exciting piece produce the ultraharmonic resonance 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 dynamicstress to subdue the unrelieved stress of workpiece.
Outstanding advantage of the present invention 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 of oscillating aging and exciting piece that can be used for the high natural frequency workpiece is adjustable within the specific limits, and it is applied widely.
2, this apparatus structure compact.

Fig. 1 is that high natural frequency workpiece according to the invention is with ultraharmonic resonance formula vibration ageing device structural representation.
Fig. 2 is the work synoptic diagram of high natural frequency workpiece according to the invention with ultraharmonic resonance formula vibration ageing device.
Embodiment
Below through accompanying drawing and embodiment technical scheme of the present invention is described further.
High natural frequency workpiece according to the invention is with ultraharmonic resonance formula vibration ageing device, comprises adjustable damping 1, adjustable non-linear spring 2, exciting piece 3 and vibrator 4.
Map 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 systems.
The parameter of excited frequency, adjustable damping 1 and adjustable non-linear spring 2 through changing vibrator 4 makes exciting piece 3 have different excited frequencies, thereby can satisfy the oscillating aging requirement of different-stiffness workpiece.
