1. Machine bed and workbench: The machine bed adopts a welded box structure, which is mainly used to support other parts. The inner cavity has a hydraulic pool and a cooling liquid pool. The workbench is a casting and is used for receiving materials, installing clamping devices and saw frames. .
2. Main transmission device: The main transmission adopts worm gear transmission mode, which is composed of motor, belt pulley, worm gear transmission, saw wheel box and saw wheel. It is mainly used to transmit torque and drive the band saw wheel to rotate in order to achieve cutting motion. By changing the belt position on the pulley, the speed can be changed.
3. Saw band tensioning mechanism: It is composed of a driven gear, a sliding seat, a sliding block, a screw rod, and a nut. The band saw blade can be tensioned by moving the driven wheel to ensure a certain formation between the band saw blade and the rim of the saw wheel. The pressure generated enough friction force to drive the saw blade to rotate and realize the cutting motion. The tension force can be determined by the force measuring wrench.
4. Working clamping mechanism: working clamping adopts a mixed method of hydraulic and manual clamping. Manual clamping is through the handwheel screw nut and rack gear, so that the clamp can move to achieve the purpose of clamping and loosening. Hydraulic clamping is controlled by hydraulic cylinders and manual valves to achieve clamping and loosening.
5. Saw band guide: It is composed of left and right guide arms and guide heads. The guide head is composed of guide rollers and guide blocks. It is mainly used to twist the band saw blade to a certain angle to make it perpendicular to the work surface to ensure the correct position of the saw blade. Improve cutting accuracy.
6. Cooling system: It is composed of a coolant tank, a cooling pump, a pipe, a valve, and a nozzle to ensure that sufficient coolant is supplied to the cutting area to improve the cutting effect and the service life of the saw band and the accuracy of the cutting section. For removing chips from the teeth.
7. Material bearing frame: It is composed of rollers, brackets and material holders to support longer workpieces and make them parallel to the workpiece table to ensure normal cutting.
