Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, provide one electric clamping device to drive contact roller pressure action, have structure simple, guarantee the safety of job site, noise is little, the electronic dipper crowding gear of the stirrup bender of cleaning ambient.
The technical scheme solved the problems of the technologies described above is: a kind of electronic dipper crowding gear of stirrup bender, described electronic dipper crowding gear comprises: be arranged on a pair traction drive axle that cabinet is parallel to each other and the compression wheel shaft that axle sleeve is housed for a pair, is connected traction wheel and contact roller in one end of described traction drive axle respectively with one end of described compression wheel shaft; Pressure post and spring is respectively arranged with at described axle sleeve end face and bottom surface, described pressure column top contacts electronic right depression bar one end and electronic left depression bar one end respectively, an electric clamping device is provided with between the electronic right depression bar other end and the electronic left depression bar other end, described electric clamping device comprises: electric expansion bar, at the other end of the right depression bar of one end hinged electric of electric expansion bar; The other end of electric expansion bar is articulated and connected one end of bar, and the screw rod of the connecting rod other end is through the ladder hole of the electronic left depression bar other end; Be equipped with locknut in the screw rod end of connecting rod, the screw rod in locknut and described ladder hole between circular bead surface is set with multiple spring leaf.
Preferred version is: the other end of described traction drive axle connects rotating power source; Reinforcing bar is between traction wheel and contact roller.
Preferred version is: the side of described electronic right depression bar one end and the side of electronic left depression bar one end are hinged on cabinet respectively by connecting pin, the opposite side of electronic right depression bar one end and the opposite side of electronic left depression bar one end are pressed in pressure column top, and described pressure post protrudes the upper end face being arranged on cabinet.
The invention has the beneficial effects as follows: the present invention overcomes the defect of prior art, tool of the present invention has the following advantages:
First, electric clamping device eliminate the complicated incidental whole annex of pneumatic system, only need power supply, structure is simple, operation is simple and reliable, keeps away pneumatic system and there is hidden danger, guarantees the safety of job site, noise is little, cleaning ambient, reduces operation and maintenance cost;
Secondly, the drafts of the control contact roller that electric clamping device energy is precise and stable, the stroke of the electric expansion bar of electric clamping device is by built-in motor driving device transmission mechanism control, can by controlling the start-stop of built-in motor and then controlling the stroke of expansion link, because electric expansion bar is mechanically operated telescoping mechanism, being different from cylinder is the telescoping mechanism utilizing gas push to complete, gas has compressibility and can not accurately locate, and electric expansion bar can arrive the telescopic location wanted accurately, can allocation position sensor, sensor is coordinated to complete accurate position control, can realize for different bar diameters, be pressed to corresponding position accurately, make crush suitable, be convenient to automatic control.
Again, electric clamping device forms elastic buffering mechanism by electric expansion bar, connecting rod, spring leaf and locknut, this elastic buffering mechanism can suppress when light circle raw material or Ribbed Bar raw material profile irregular, in distraction procedure, cause contact roller and the squeezed broken existing picture of traction wheel, reinforcing bar to be extruded distortion or skid (namely occurring not pressing tightly skidding when bar diameter is less) existing picture to contact roller and traction wheel rebounce, impacting rebound equally also can be avoided to cause the damage of electric expansion bar to electric expansion bar portion.
