Abstract
The utility model relates to a preventer for a woodworking circular-saw, belonging to a safety device which is especially designed for a wood saw. A back saw guard and a front saw guard are installed inside a reaming hole on the upper part of a guiding knife and can rotate around the reaming hole. The inner part of a reaming hole on the lower part of the front saw guard is provided with a shifting handle which is used for shifting the tail end of a piece of sawn wood and preventing fingers from getting close to a saw blade. The guiding knife is installed on the back part of the saw blade in the same plane with the saw blade. The utility model has the advantages of simple structure, small size, convenient operation, low cost and complete protective property; the preventer for a woodworking circular-saw can be used on various types of circular-saw machines.
Description
The utility model belongs to and is the custom-designed safety device of wood saw.
Manually-operated woodworking circular sawing machine is the indispensable equipment of capital construction building site and woodenware processing factory, but because manually feeding is often hindered the hand accident, or because of the timber humidity, is with knot and saw blade to grind and pure etc. timber is flown out hurt sb.'s feelings.In recent years for preventing the generation of above-mentioned accident; designed multiple safety device both at home and abroad; wherein the International Labor Office that is translated with labour protection in 86 years compiles the saw blade rear portion that " labour protection encyclopedia " introduce chopper is housed; the form of the whole bow saw cover of buck upper support is more; though this device can prevent that timber from flying out and hurt sb.'s feelings; but hand still might be run into saw blade during feeding, the hand accident occurs hindering.
The purpose of this utility model is to provide a kind of barrier propterty complete, avoids hindering the hand casualty accident, and is simple in structure, easy to operate, cheap woodworking circular sawing machine safety device.
The technical solution of the utility model is as follows, it by guiding cutter, back saw cover, preceding saw cover, pull out hand four parts and form, the preceding saw cover that pulls out hand is housed on the back saw cover of arc guide groove and the riser is loaded in the fraising on guiding cutter top having on the riser, having lead on the guiding cutter cooperates with the arc guide groove of back saw cover, back, preceding saw cover can relatively rotate certain angle around pin joint, it pulls out hand is satisfied with in the bottom fraising of preceding saw cover, and rotates relative to the preceding cover of sawing.Thereafter saw cover and preceding saw cover are respectively to be formed with the connection of arc gusset piece by the riser of pair of parallel in the guiding cutter.
In the utility model, hinged place and the preceding saw cover that also can saw cover, preceding saw cover in guiding cutter and back are equipped with locking device with the hinged place of pulling out hand.
When using this device, the guiding cutter is fixed by bolts to saw blade rear portion on the buck, and with saw blade at grade, when feeding, lift and pull out hand and preceding saw cover, make timber send into and push ahead, saw cover after the jack-up is because the circular arc anti-back tooth of the deadweight of back saw cover and saw cover bottom, back can not retreat timber; After timber entered the guiding cutter, guiding cutter supporting saw kerf made it not binding, and prevented that sawn timber from running line and appearance " wood later " phenomenon, and when timber afterbody during near saw blade, the hand that pulls out of saw cover pushes timber in the saw blade before putting down.
Advantage of the present utility model is simple in structure, and barrier propterty is complete, and volume is little, and is in light weight, easy to operate, practical, avoids hand and saw blade approaching, prevents to hinder the hand casualty accident, is convenient to use on various circular sawing machine.
Accompanying drawing 1 is a woodworking circular sawing machine safety device schematic diagram.
Most preferred embodiment of the present utility model as shown in Figure 1, arc length is greater than (π)/2, internal diameter is that the guiding cutter 1 of 310mm has lead, dress back saw cover 2 and preceding saw cover 3 in the fraising of top, thereafter saw cover 2 and preceding saw cover 3 are respectively to be formed with the connection of arc gusset piece by the riser of pair of parallel in guiding cutter 1, have the arc guide groove that matches with lead on the cutter 1 that leads on back saw cover 2 risers, the riser lower limb has circular arc anti-back tooth, before the lower hinge of saw cover 3 pull out hand 4 in order to what stir timber, at guiding cutter 1 and back saw cover 2, the hinged place of preceding saw cover 3 and preceding saw cover 3 are equipped with clamping screw 5 with the hinged place of pulling out hand 4.
Among the above embodiment, the physical dimension of its guiding cutter 1, back saw cover 2, preceding saw cover 3 can be determined according to the diameter of circular sawing machine saw blade 6.
Claims (2)
1, a kind of woodworking circular sawing machine safety device, form by guiding cutter 1, back saw cover 2, preceding saw cover 3, group hand 4, it is characterized in that in the guiding cutter 1 top fraising that has lead, installing and to saw cover 2 and preceding saw cover 3 in the back in relative rotation around it, thereafter saw cover 2 and preceding saw cover 3 are respectively to be formed with the connection of arc gusset piece by the riser of pair of parallel in guiding cutter 1, have the arc guide groove that cooperates with lead on the cutter 1 that leads on back saw cover 2 risers, and in the fraising of the lower end of preceding saw cover 3, group hand 4 is housed.
2, safety device according to claim 1 is characterized in that hinged place and the preceding saw cover 3 of sawing cover 2, preceding saw cover 3 in guiding cutter 1 and back are equipped with locking device 5 with the hinged place of pulling out hand 4.
