The utility model adopts servomotor to coordinate centre of gyration device to control saw frame mechanism and rotates adjustment saw cutting angle, makes it can carry out angle sawing between+70o ~-45o, thus beats tooth when preventing 200X150 square steel tube 70 degree of corner saws from cutting; Stock-removing efficiency is high, saw kerf is narrow, energy-conservation material-saving.
Preferably, described swinging mounting comprises rotating beam and two rotation columns, be rotationally connected with central rotating shaft in the middle part of described rotating beam, described saw frame mechanism is fixed on the bottom of two rotation columns, and every root rotates column top and is equipped with the hoist cylinder controlling the lifting of saw frame mechanism.
This kind of structure adopts swinging mounting to carry out the angle of auxiliary adjustment saw frame mechanism sawing, makes the adjustment of its saw cutting angle more reliable and more stable, adopts hoist cylinder to control the lifting of saw frame mechanism simultaneously, makes its sawing efficient stable more.
Preferably, support frame as described above comprises fixed cross beam and two vertical columns, and described centre of gyration device is fixed in the middle part of fixed cross beam.
This kind of structure makes sawing machine overall structure more solid and reliable, and ensures the reliably easier for installation of centre of gyration device.
Preferably, the described centre of gyration device slewing limit block that comprises rotary support, be arranged on the main spring of rotary support inside, central rotating shaft and be set in outside central rotating shaft.
This kind of structure makes the control of centre of gyration device to swinging mounting more reliable and more stable.
Designed by the utility model is mainly cut for 200X150 square steel tube 70 degree of corner saws, it adopts servomotor to coordinate centre of gyration device to control saw frame mechanism and rotates adjustment saw cutting angle, make it can carry out angle sawing between+70o ~-45o, thus beat tooth when preventing 200X150 square steel tube 70 degree of corner saws from cutting; Stock-removing efficiency is high, saw kerf is narrow, energy-conservation material-saving.
