20140260873 | SAW BLADE TENSION ADJUSTING APPARATUS FOR BAND SAW MACHINE - A saw blade tension adjusting apparatus of a band saw machine includes a retaining base, a movable base movably connected with the retaining base through two opposite sliding shafts, and a control unit having a handle and a cam connected with the handle so as to be driven to rotate between a tightening position and a loosening position. When the cam is located at the tightening position, the movable base is lifted by a large diameter portion of the cam to tighten the tension of a saw blade, and when the cam is located at the loosening position, the movable base is moved downwards to lean on a small diameter portion of the cam for loosening the tension of the saw blade. | 09-18-2014 |
20140260870 | VIEWING WINDOW FOR BAND SAW MACHINE - A viewing window for a band saw machine includes a cover plate and a transparent plate mounted between two locating portions of the cover plate and facing a window opening penetrating through external and internal sides of the cover plate, such that the transparent plate is located between the locating portions of the cover plate. Thus, the transparent plate can be quickly and conveniently assembled on the internal side of the cover plate. | 09-18-2014 |
20120138709 | DISK SPRAY DEVICE - A disk spray device includes a shell having a bottom air inlet and a lateral air outlet, a fan rotatably mounted in the shell for streaming air through the bottom air inlet into the shell and then out of the lateral air outlet, and a spray tube mounted around an outer periphery of the shell and having a plurality of nozzles near the lateral air outlet of the shell. The spray tube is adapted to be connected with a water supply device such that water running in the spray tube can be sprayed into water mist through the nozzles of the spray tube. The water mist can be further delivered far way by the wind that is exhausted out of the lateral air outlet of the shell by the fan. | 06-07-2012 |
20110167974 | Emergency stop device for band saw - 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. | 07-14-2011 |
20110005364 | Band saw having worktable whose horizontal rotary angle is adjustable - 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. | 01-13-2011 |
20100282039 | SPREADER ASSEMBLY FOR TABLE SAW - A spreader assembly includes a spreader having a notch and two opposite indentations at a periphery of the notch, a holder, on which an anti-kickback pawl device is mounted, having a groove for insertion of the spreader, and a controller rotatably mounted to the holder and rotatable relative to the holder between a first position where two block portions of the controller are engaged with the indentations of the spreader for mounting the holder to the spreader, and a second position where the block portions of the controller are disengaged from the indentations of the spreader for allowing detachment of the holder from the spreader. | 11-11-2010 |
