Description
Technical field
The utility model relates to the reinforcing bar processing production equipment, particularly a kind of rotary reinforced bar shear.
Background technology
Cold rolled reinforcing steel bar with ribs is processed by wire rod, in the cold rolled reinforcing steel bar with ribs machining production line, have the equipment such as pay off rack, reason wire frame, descaling mill, straightener, tilting trestle and steel bar cut-off device, steel bar cut-off device is that the bar cutting with straightening is the device of isometric reinforcing rod between straightener and tilting trestle.At present, the steel bar cut-off device in the cold rolled reinforcing steel bar with ribs machining production line adopts vertical punching mechanism, namely by cutting off reinforcing bar perpendicular to the quick downward impulse force of the punching tool utilization of reinforcing bar.Because the cutter of vertical punching mechanism has a process that is returned to original position after moving downward and cutting off reinforcing bar, the reinforcing bar that cutter can hinder steel bar cut-off device the place ahead on the production line in this process is mobile backward, the time that a pause namely must be arranged in cutting-off process, cause the production efficiency of reinforcing bar machining production line lower.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary reinforced bar shear, and when on the reinforcing bar machining production line reinforcing bar being sheared, reinforcing bar can not pause on the reinforcing bar machining production line.
Rotary reinforced bar shear described in the utility model, comprise gear housing, servomotor, driving gear, driven gear, active tool rest, driven tool rest, reduction box and belt pulley transmission mechanism, at gear housing driving shaft and driven shaft are installed, driving shaft and driven shaft can be with respect to gear housing around separately axis rotations, driving gear and driven gear are positioned at gear housing, it is installed in respectively driving shaft and is connected with driven shaft with driving shaft and is connected with driven shaft key, and driving gear and driven gear are meshed.
Initiatively tool rest and driven tool rest are cylindrical, initiatively tool rest is fixed on the driving shaft and the driving shaft coaxial line, driven tool rest is fixed on the driven shaft and the driven shaft coaxial line, initiatively tool rest and driven tool rest are positioned at the outer the same side of gear housing, have the shear reinforcement of plan therebetween and pass through the space, on the face of cylinder of active tool rest and driven tool rest, be fixed with respectively initiatively cutting knife and driven cutting knife, when the active cutting knife goes to the extreme higher position, driven cutting knife then goes to extreme lower position, this moment, two cutting knife cutting edges were just relative up and down, and had the bar cutting gap.
The output shaft of servomotor is connected with reduction box input shaft by the belt pulley transmission mechanism, and reduction gearbox output shaft is connected with described driving shaft.
During work, reinforcing bar passes through between active tool rest and driven tool rest, monitor and follow the tracks of by the speed that electric control system is advanced to reinforcing bar, when reinforcing bar advances a preseting length, electric control system makes its startup to the servomotor transmitted signal, power passes to reduction box input shaft by the belt pulley transmission mechanism, through behind the reduction box, power drives driving shaft by reduction gearbox output shaft output and rotates, driving shaft drives driving gear and the initiatively tool rest rotation on it again, simultaneously the driven gear that drives with its engagement of driving gear rotates, and then drive driven tool rest by driven shaft and rotate synchronously, has namely realized the initiatively synchronous rotation of tool rest and driven tool rest.When the active cutting knife on the active tool rest went to the extreme higher position, the driven cutting knife on the driven tool rest went to extreme lower position, and two cutting knifes are just in time just relative up and down, will just cut off from the reinforcing bar that passes through between active tool rest and the driven tool rest.After reinforcing bar was cut off and cut off, initiatively tool rest and driven tool rest were rotated further to original position, and at this moment, electric control system makes it out of service to the servomotor transmitted signal.
Rotary reinforced bar shear described in the utility model, because initiatively cutting knife and driven cutting knife are installed in respectively on tubular active tool rest and the driven tool rest, add man-hour at bar cutting, the direction of motion of cutting knife is always the tangential of tool rest, when cutting knife is sheared reinforcing bar, can not cause obstruction to advancing of reinforcing bar, therefore reinforcing bar can not pause, improved reinforcing bar processing efficient on machining production line.Simultaneously the utility model employing servomotor can be realized monitoring and the tracking to the reinforcing bar pace, so that the pace of the linear velocity of active tool rest and the motion of driven tool rest and reinforcing bar is consistent, guarantees that the bar cutting position is accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of tool rest and driven tool rest initiatively in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, this rotary reinforced bar shear comprises gear housing 15, servomotor 9, driving gear 8, driven gear 7, active tool rest 4, driven tool rest 3, reduction box 12 and belt pulley transmission mechanism 16, on gear housing 15, by bearing driving shaft 6 and driven shaft 5 are installed, driving shaft 6 and driven shaft 5 can be with respect to gear housing 15 around separately axis rotations, driving gear 8 and driven gear 7 are positioned at gear housing 15, are connected key with driven shaft with driving shaft 6 on it is installed in respectively driving shaft 6 and driven shaft is connected and are connected, and driving gear 8 and driven gear 7 are meshed.
Such as Fig. 1, shown in Figure 2, initiatively tool rest 4 and driven tool rest 3 are cylindrical, initiatively tool rest 4 is fixed on the driving shaft 6 and driving shaft 6 coaxial lines, driven tool rest 3 is fixed on the driven shaft 5 and driven shaft 5 coaxial lines, initiatively tool rest 4 and driven tool rest 3 are positioned at gear housing 15 outer the same sides, initiatively tool rest 4 and 3 of driven tool rests have the space that the plan shear reinforcement passes through, on the face of cylinder of active tool rest 4 and driven tool rest 3, be fixed with respectively initiatively cutting knife 2 and driven cutting knife 1, when active cutting knife 2 goes to the extreme higher position, initiatively 2 of cutting knifes go to extreme lower position, this moment, two cutting knife cutting edges were just relative up and down, and has the bar cutting gap, active cutting knife 2 cutting edges that namely reinforced shear can be cut off and the gap between driven cutting knife 1 cutting edge.
