Abstract:
A workpiece feeding device used in a saw machine is disclosed to include a carrier having a base frame movably mounted on the machine base of the saw machine and an angle scale fastened to the base frame, a fence unit having a rip fence pivotally mounted on the base frame of the carrier and biasable relative to the angle scale, a magnetic plate assembly mounted on the base frame of the carrier and carrying a magnetic strip, and a magnetic sensor mounted in the fence unit and movable with the fence unit to measure the biasing angle of the fence unit relative to the angle scale subject to change of magnetic induction between the magnetic sensor and the magnetic strip.
Abstract:
An emergency stop device for a band saw includes a brake member moveable between a standby position and an active position where the brake member firmly urges and stops a running wheel of the band saw, around which a band saw blade is looped. The brake member is held by a retainer at the standby position when the emergency stop device is inactive. When the emergency stop device is started, the retainer is separated apart from the brake member for enabling the brake member to move by an actuation of a spring member from the standby position to the active position so as to stop the cutting motion of the band saw blade.
Abstract:
A band saw includes a machine base having a shaft hole for a saw blade to pass through, and a worktable having a shaft tube for the saw blade to pass through. By means of the insertion of the shaft tube of the worktable into the shaft hole of the machine base, the worktable is rotatable relative to the saw blade for adjustment of the horizontal rotary angle thereof.
Abstract:
Installed in a band saw formed of a frequency converter, a motor, a driving wheel set and a band saw blade, a cutting speed display device is disclosed to include a modulator electrically connected to the frequency converter to output a linear modulation signal to the frequency converter for modulating the frequency of the output electrical power of the frequency converter so as to regulate the speed of the motor, and a display device that has a circuit device electrically connected to the modulator for receiving the linear modulation signal outputted by the modulator and converting the received linear modulation signal into a band saw blade cutting speed subject to one of a number of calculation modules set therein for enabling the band saw blade cutting speed to be displayed on the display panel. Thus, the cutting speed display device indicates the cutting speed of the band saw blade of the band saw in real time, and eliminates the problem of floating of the displayed data.
