Description

A kind of vibration calendering device

Technical field

The utility model relates to a kind of machining equipment, specifically is a kind of novel vibrating calendering device.

Background technology

Traditional rolling and processing is that high rigidity and smooth roller are contacted with the metal surface roll extrusion, plastic working method a kind of who makes its superficial layer that surface roughness take place to improve after the plastic deformation of local trace, it mainly relies on the plasticity and the ductility of material and processes, the material that is fit to is limited, tonnage is big, often weigh surface of the work wounded, and the rigidity of equipment is had relatively high expectations, can't generally promote the use of.The ultrasonic wave roll extrusion that occurs is radially to apply the technology that rolling and processing is carried out in ultrasonic vibration at workpiece at present, because the application of ultrasonic vibration can improve metal surface material plasticity, improved the rolling and processing condition, but hyperacoustic output is stressed and the influence of workpiece size and contact area is bigger, can not resonate in use, output amplitude is very little, make the processing effect instability, and working (machining) efficiency is lower.

The utility model content

Technical problem to be solved in the utility model has provided a kind of novel vibrating calendering device, it is to adopt giant magnetostrictive rod as vibrating elements, with high-accuracy and constant width of cloth control circuit control Oscillation Amplitude, utilize the plasticity of metal, apply certain precompression in the metal surface, increase the plasticity of metal surface material with the vibration of high frequency trace, and make the process equipment of its surface peening polishing.

Vibration calendering device described in the utility model, comprise handle of a knife, roller shaft, bearing, press polish roller, wherein roller shaft is installed in the handle of a knife leading section by bearing, the press polish roller is supported on the roller shaft, in addition, it also has controller, giant magnetostrictive rod, coil, vibration output shaft and forward and backward magnetic bias piece, and described magnetostrictive rod is located in the inner chamber at handle of a knife rear portion, and the two ends that forward and backward magnetic bias piece is installed in magnetostrictive rod respectively provide bias field for magnetostrictive rod; Coil in the magnetostrictive rod outside along the handle of a knife lumen shaft to installation, and by control cable be connected with controller outside; One end of vibration output shaft contact with preceding magnetic bias device, and the other end and press polish roller keep necessarily vibrating the gap, and the butterfly spring is arranged between the boss face of vibrating output shaft and the inner chamber front face precompression is provided.

Can also be provided with vibrating sensor on above-mentioned vibrating shaft output shaft, vibrating sensor is connected with controller by data wire.This vibrating sensor feeds back to controller to the vibration signal on the vibrating shaft output shaft, and controller is adjusted output signal according to the amplitude of setting in good time, makes the vibration output amplitude keep stable.

The utlity model has the high efficiency of traditional roll extrusion and the advantage that the ultrasonic wave roll extrusion improves material plasticity, and simple in structure, volume is little, and coupling is convenient, so both can process the high hardness material surface, also can carry out polishing processing on the surface of arbitrary shape.Owing to adopted giant magnetostrictive rod and permanent width of cloth control circuit, make the amplitude output of device when roll extrusion keep constant simultaneously, guaranteed the surface effect of rolling and processing, the metal surface after the processing is level and smooth as mirror; Hardness to surface of the work when improving surface roughness has the first mate to improve.45 for example modified steel vibrate press polish through after the common turning, and surface roughness can reach Ra0.01 μ m, case hardness can reach HB440, the surface-brightening unanimity; Use through long-term processing, apparent mass is reliable and stable.Because in rolling and processing, applied the vibration of high frequency, effectively lowered the surface of the work stress relaxation number, improved the fatigue strength and the life-span 30% of workpiece.
