Description
Technical field
The utility model belongs to bending machine technical field, refers in particular to a kind of bending machine.
Background technology
Bending machine is one of steel bar processing machinery, and its main operational principle is: placed between central shaft and bend pipe axle by reinforcing bar end, utilize the rotation of rolling disc, bend pipe axle is produced around central shaft and rotates, and then had a certain degree by bar bending.At present, bending machine of the prior art is all adopt the structure of worm and gear to carry out transmission rolling disc, and this structure exists following defect: one is that the transmission efficiency of worm and gear is lower; Two is that Worm Wheel System must have lubricating oil to lubricate, and easily produces the phenomenon of oil dripping leakage of oil; Three is that worm gear transmission ratio is easier to wearing and tearing; Four is that Worm Wheel System noise ratio is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of bending machine, it have employed involute gear and carries out transmission, transmission efficiency is higher, structure is more durable, under equal behaviour in service, the moment of torsion provided is larger, longer service life, and this structure does not define weight bending direction, any direction is bending makes operation more random and convenient.
The purpose of this utility model is achieved in that
Bending machine, the workbench of body is provided with rolling disc, and the both sides that rolling disc is relative are provided with longitudinal baffle, and described rolling disc is in transmission connection the gear drive be located in body, drive motors by belt, the work of belt pulley driven gear transmission mechanism, and then makes rolling disc rotary work.
The be in transmission connection concrete structure of gear drive of above-mentioned rolling disc is: comprise driving shaft, reducing gear wheel shaft and rolling disc main shaft, the lower end of driving shaft is arranged on by the belt pulley of belt connection drive motors, the upside of driving shaft is provided with output gear, output gear is connected with a joggle the reduction gearing be arranged on the upside of reducing gear wheel shaft, the gear wheel engaged transmission tooth on the pinion on the downside of reducing gear wheel shaft and rolling disc main shaft.
Above-mentioned output gear is one-body molded on driving shaft.
Above-mentioned output gear, reduction gearing, pinion and gear wheel are all involute gears.
Above-mentioned rolling disc is arranged on rolling disc main shaft, is fixed with round overcoat between rolling disc and rolling disc main shaft, and the baffle plate that longitudinal baffle is installed is provided with roller, and baffle plate is across the upside at rolling disc and longitudinal baffle.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model adopts gear drive, and than the structure of existing Worm Wheel System, the efficiency of transmission is higher, and moment of torsion is larger, and bending power is larger.
2, structure of the present utility model adopts butter lubrication, and maintenance cost is low, can not produce oil leakage phenomenon, and the bearing capacity of involute gear is strong simultaneously, and under equal behaviour in service, the utility model can improve 2-3 years service life compared to existing technology.
3, the utility model is owing to have employed gear drive, and therefore the bending direction of machine does not define, and any direction can be adopted to operate moment reinforcement etc.
