Part 19 is transported in the steel band range of work of knife 17, starts band driving device for cutter, steel band knife 17 can be to part to be processed 19
It is processed.
Steel is usually to be welded using a steel band two ends and polish smooth the loop configuration to be formed with knife, is added by the present invention
The band driving device for cutter of work apparatus system is tensed and driven, and is run by the linear velocity of setting.Because there is shape in steel band knife itself
Shape error, and its power driven effect, steel with the region part that knife is tightened up can produce up and down tremble, should up and down tremble
Amplitude is to show as band to chatter dynamic amplitude.Limit steel with knife the region up-down vibration space, it is possible to reduce it and shake
Dynamic amplitude, mainly including following several respects content：
The present invention uses rigid plane method for supporting, sets rigid support in parallel to put down running face bottom with knife
Face, reduces the space trembleed with knife, so as to reduce the Oscillation Amplitude with knife in supporting zone.On the one hand, due to the rigid support
Plane and with gapless between knife or only minimum gap, and the two has good location matches conformity relation, rigidity
Supporting plane will not produce upward thrust to steel with knife, so rigid plane only has minimum friction to hinder steel with knife
Power, even without frictional resistance；On the other hand, because rigid plane typically uses high-abrasive material or composite abrasion resistance material system
Make, and with higher surface quality and plane precision, can reduce and steel is with the frictional force between knife, also improve rigidity
Plane its own face quality and dimensional stability, can keep and with the location matches conformity relation between knife for a long time, so that
Reduce steel with knife planar support region Oscillation Amplitude.
The present invention uses piecewise combination method for supporting, is being tightened up the region for converted products with knife while setting multistage
Planar support, each section supports and with there is certain position requirement between knife installation site, can mutually combine to form complete band knife
Support, so as to limit the amplitude with knife in converted products domain oscillation.First, band driving device for cutter can make band knife be tightened up to be formed
The two ends of straightway are maintained in sustained height or same level, it is ensured that with knife two ends in the process of running in stabilization
Position, and provide position reference for middle rigid support；Secondly as steel is tightened up the processing district to form straightway with knife
Typically there is a longer distance in domain, and steel band knife is flake structure, and being tightened up, the area rigid to form straightway is relatively low,
Larger vibration deformation can occur during operation, so by setting multistage rigid support, each section of rigid support group in machining area
Close and form a bigger rigid supporting plane, each position of rigid supporting plane contacted with knife to be formed with being tightened up with knife
The two ends of straightway are in sustained height (same level).Collective effect of both more than, reduces steel band knife
In the vibration deformation space of machining area, while integral rigidity of the steel with knife converted products region is added, so as to improve steel
System band knife operation stability.
The present invention uses flexible floating dynamic pressure clamping method, and relocatable Compliant pressure dress is installed above rigid supporting plane
Put, steel is run with knife between the seal face and rigid supporting plane of flexible floating presure hold-down device, equivalent to steel band knife
It is clamped between two smooth flats, Oscillation Amplitude of the steel with knife in converted products region is further decreased.Compress dress
The plane contacted in putting with knife has higher surface quality, the accuracy of form and position and wearability, and steel can be kept for a long time
The stability run with knife.
The present invention utilizes precision vibration damping method of the steel annular with knife, steel annular band knife greatly improved stable
Property, its Oscillation Amplitude is significantly reduced, makes the cutting edge with knife its cutting edge front end and bipeltate hair during converted products
It is the Metal Cutting run at high speed a line that the position of base contact, which is just more nearly, so as to greatly reduce vibration of the steel with knife
Amplitude.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
