Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a bottom plate 1, wherein a vertical support frame 2 is arranged on the bottom plate 1, a pressure rod 3 capable of swinging left and right is hinged on the support frame 2, and a rotatable cutting disc 4 is arranged on the pressure rod 3; an inner shell and an outer shell are sleeved outside the cutting disc 4, the inner shell 5 is fixed with the pressure rod 3, the outer shell 6 can rotate along the inner shell 5, and a torsion spring is arranged between the inner shell and the outer shell; two clamping devices are symmetrically arranged on the base plate 1 in front and back directions relative to the cutting disc 4, each clamping device comprises a fixed plate 7 fixed on the base plate 1 and a movable plate 8 positioned on the left side of the fixed plate 7, a movable guide rod 9 penetrates between the movable plate 8 and the fixed plate 7, and a pressure spring is arranged between the left end of the guide rod 9 and the left side face of the movable plate 8; a rope 10 is connected between the right end of each guide rod 9 and the right end of the pressure rod 3.
In order to realize the rotation of the cutting disc 4, the right end of the pressure rod 3 is fixedly provided with a motor, and the motor and the cutting disc 4 realize the co-rotation through a chain and a chain wheel.
In order to limit the rotation angle of the outer shell 6, a positioning rod 11 for limiting the rotation of the outer shell 6 is arranged on the inner shell 5.
In order to facilitate the reversing of the rope 10, a fixed pulley 12 is arranged on the bottom plate 1, and the middle part of the rope 10 is reversed by the fixed pulley 12.
In order to facilitate cutting, the bottom plate 1 is provided with a cutting groove 13 corresponding to the cutting disc 4.
When the utility model is used, firstly, the steel bar passes through the front clamping device and the rear clamping device, so that the steel bar is positioned between the movable plate 8 and the fixed plate 7 of the clamping devices, and the steel bar is positioned below the guide rod 9; then the motor can be started, the motor drives the cutting disc 4 to rotate at a high speed through the chain wheel and the chain, and the left side of the pressure rod 3, namely the position of the cutting disc 4, is in a high position, namely the state shown in the attached figure 2, because the motor is arranged at the right end of the pressure rod 3 and the weight of the motor is heavier.
Before cutting, the right end of the pressure lever 3 is at a low position, so the pressure lever 3 cannot strain the rope 10, the left end of the guide rod 9 can be positioned at the left side of the stroke of the guide rod 9 under the action of a pressure spring, and meanwhile, the two ends of the pressure spring are respectively fixedly connected with the left end of the guide rod 9 and the left side surface of the movable plate 8, so when the guide rod 9 is positioned at the left side of the stroke of the guide rod, the movable plate 8 is also positioned at the left side of the stroke of the movable plate 8; at this moment, the movable plate 8 can not extrude the tight reinforcing steel bar, the reinforcing steel bar can move freely, and the position of the reinforcing steel bar can be adjusted at the moment.
When cutting, the left end of the pressure lever 3 is pressed by hand, at the moment, the pressure lever 3 is hinged with the support frame 2, so that the cutting disk 4 on the pressure lever 3 can move downwards, the cutting disk 4 moves downwards, and after the shell 6 of the cutting disk 4 is contacted with the bottom plate 1, the shell 6 can rotate, so that the shell 6 can rotate clockwise; at the moment, the cutting disc 4 can contact the reinforcing steel bars to cut the reinforcing steel bars; because the outer shell 6 is in contact with the bottom plate 1, most of sparks can be guaranteed to be positioned inside the two shells under the double action of the outer shell 6 and the inner shell 5, and the sparks are prevented from splashing.
Simultaneously at the in-process that depression bar 3 pressed down, the right-hand member of depression bar 3 rises, then stimulates rope 10, and guide arm 9 moves right, can drive fly leaf 8 through the pressure spring and move right, makes fly leaf 8 extrusion tight reinforcing bar, makes the reinforcing bar unable removal, and along with the lifting of the right-hand member of depression bar 3, the reinforcing bar can be pressed more and more tightly simultaneously, especially when the cutting, can make the reinforcing bar firmly compressed tightly, has guaranteed the stability of cutting.
After cutting, the pressing rod 3 is not pressed, and at the moment, the pressing rod 3 can be reset to the state shown in the attached drawing 1 because the motor at the right end of the pressing rod 3 is heavy; at the moment, the clamping device does not clamp the reinforcing steel bar any more; the housing 6 is also restored to the original position; when the next cutting is performed, the pressing rod 3 is pressed only after the position of the steel bar is adjusted.
This device is through setting up two-layer casing inside and outside, through fixed with inner shell 5, and shell 6 rotates, can make cutting disc 4 when the cutting, and shell 6 can effectual parcel cutting disc 4, the effectual splashing that blocks the spark.
This device is through setting up two clamping device around, through utilizing when cutting, presses the action of depression bar 3, through the linkage of rope 10, has realized when depression bar 3 presses, and clamping device can press from both sides tight reinforcing bar in step, does not need extra operation, and convenient and fast is accomplishing the back at the cutting simultaneously, and the reinforcing bar can be by automatic release, the position adjustment when the reinforcing bar cutting of next time of being convenient for.
The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, has improved the portability and the security of reinforcing bar cutting greatly, has guaranteed operating personnel's safety.
