Nearly 7000 yuan of the manufacturing cost of corresponding knife machining mechanism, is 100 calculating by an annual production, can save nearly 70 for enterprise every year
Ten thousand yuan of cost.
（2）Fundamentally solve the Leakage of conventional hydraulic knife striking cylinder.Knife machining mechanism of the present invention uses pneumatic and gas
Cylinder is placed on outside ram, will not cause the failure of other functional parts after installation during use because of leakage.
（3）Complete to forge a knife action by the cooperation of external cylinder and lever, using the fixed cylinder roller on lever
The mode of bearing, is realized using lever construction and forged a knife, it is only necessary to which the less power of forging a knife can complete action of forging a knife.With in BT50 types T
Exemplified by being applied on type ram main shaft, action of forging a knife can be achieved in the power of forging a knife that knife machining mechanism of the present invention provides 0.7MPa, and traditional
Hydraulic pressure knife striking cylinder needs to realize that main shaft is forged a knife by 4.0MPa or so hydraulic oil, therefore knife machining mechanism of the present invention can be significantly
Save the energy.
（4）It is simple in construction, install and easy to maintenance.Because cylinder is external, it can be watched in real time during main shaft is forged a knife
The running status of cylinder, understands whether whole process of forging a knife is normally carried out.
（5）Using compressed air as power source, compressed air is clean energy resource, thus knife machining mechanism of the present invention compared to
Traditional knife machining mechanism using hydraulic oil as power source, has the advantages that environmentally safe.
（6）Using the outer shroud of cylinder roller bearing as fulcrum of forging a knife, the fulcrum of forging a knife of this form, its contact surface is cylinder
The outer ring surface of roller bearing, the outer ring surface is cylindrical surface, can be prevented effectively from the deflection load caused by bias when forging a knife, make
Action of forging a knife can be smoothly completed, and reliability is high.
