Abstract
The utility model relates to a saw band fracture safety guard for a band sawing machine, comprising a backstand arranged on a saw log, wherein, the backstand is provided with a tension slide block which can slide left and right; the right end of a tension screw mandrel is movably connected with the tension slide block, while the left end of the tension screw mandrel slides to extend out of the backstand and is sleeved with a pressure spring and connected with a handwheel; the tension slide block is provided with a moving plate, the left side of which is correspondingly provided with a microswitch. When a saw band is in normal condition, the moving plate and the microswitch keep a certain distance from each other; if the saw band is broken, the tension slide block drives the moving plate to move to the left to contact the microswitch under the action of the pressure spring, the microswitch sends a signal to cut off the power source of a main motor, thereby protecting the safety of devices and personnel. The utility model has a simple structure and good protective value.
Description
Technical field
The utility model relates to a kind of band saw machine, specifically is a kind of band sawing machine saw band fracture safety guard.
Background technology
In band saw machine, saw band is to be stretched on the tensioning saw wheel and active saw wheel of saw frame the right and left by strainer.Described strainer is by backstand, tensioning slide block, tensioning screw mandrel, compression spring and handwheel are formed, backstand is installed on the back side, the saw frame left side, the tensioning slide block is arranged in two slide rails up and down of backstand and can horizontally slips, the right-hand member of tensioning screw mandrel flexibly connects the tensioning slide block, left end slides and stretches out backstand, and socket is compressed spring and is connected handwheel; The tensioning saw wheel is in the saw frame front, and its wheel shaft passes saw frame and is fixedly connected in the axis hole of tensioning slide block, but and with tensioning slide block move left and right.Rotation hand wheel and tensioning screw mandrel can make the tensioning saw wheel be moved to the left and the tensioning saw band.
Because band sawing machine is in the sawing operation process, as the saw band fracture takes place, power supply can not in time disconnect, and main motor will drive saw wheel and remain in operation, and therefore can cause equipment and personal safety accident to take place.
The utility model content
The technical problems to be solved in the utility model provides a kind of band sawing machine saw band fracture safety guard; make it when the saw band fracture takes place, can send signal and give electrical system; make main motor deenergization, no longer drive saw wheel and remain in operation, with protection equipment and personal safety.
A kind of band sawing machine saw band fracture safety guard described in the utility model; comprise the backstand that is installed on the saw frame; this backstand is provided with the tensioning slide block that can horizontally slip; tensioning screw mandrel right-hand member flexibly connects the tensioning slide block; left end slides and to stretch out backstand, and socket compression spring and be connected handwheel, and particularly described tensioning slide block is provided with movable plate; the corresponding microswitch that is provided with of movable plate left, movable plate are moved to the left with the tensioning slide block can contact microswitch.
During concrete enforcement, microswitch can be fixed on the saw frame or backstand of movable plate left.Described movable plate upper end can be provided with adjustment screw.
The utility model keeps a determining deviation with movable plate and microswitch under the normal condition of saw band tensioning.As the saw band fracture takes place, and the tensioning slide block just slides left under the compression spring action, and movable plate also is moved to the left and contacts microswitch with the tensioning slide block; microswitch sends signal and gives electrical system; make main motor outage, stop to drive the saw wheel running, thus protection equipment and personal safety.It is simple in structure, protective value good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1-saw frame, 2-handwheel, 3-compression spring, 4-backstand, 5-microswitch, 6-adjustment screw, 7-movable plate, 8-tensioning screw mandrel, 9-tensioning saw wheel axis hole, 10-tensioning slide block, 11-backstand hold-down nut.
The specific embodiment
As shown in Figure 1; a kind of band sawing machine saw band fracture safety guard; comprise the backstand 4 that is installed on the saw frame 1; this backstand 4 is provided with the tensioning slide block 10 that can horizontally slip, and tensioning screw mandrel 8 right-hand members flexibly connect tensioning slide block 10, and left end slides and stretches out backstand 4; and socket is compressed spring 3 and is connected handwheel 2; tensioning slide block 10 is provided with movable plate 7, the corresponding microswitch 5 that is provided with of movable plate 7 lefts, and movable plate 7 is moved to the left with tensioning slide block 10 can contact microswitch 5.Above-mentioned backstand 4 is fixed on the saw frame 1 by three nuts 11 respectively.
Microswitch 5 is fixed on the saw frame 1 of movable plate 7 lefts.Certainly, also can be fixed on the backstand 7 of movable plate 7 lefts.Described two fixed forms all have advantage easy for installation.
Described movable plate upper end is provided with adjustment screw 6, is moved to the left the shift motion that touches microswitch 5 by adjustment screw 6 conveniently adjusted movable plates 7.
Under the normal condition of saw band tensioning, movable plate 7 and microswitch 5 are kept a determining deviation, at this moment, compression spring 3 is compressed.As saw band fracture takes place; under 3 effects of compression spring; driving tensioning slide block 10 by tensioning screw mandrel 8 just slides left; movable plate 7 also is moved to the left and contacts microswitch 5 with tensioning slide block 10; microswitch 5 sends signal and gives electrical system; make main motor outage, stop to drive saw wheel and rotate, thus protection equipment and personal safety.
