Description
Technical field
The present invention relates to electric power tunnel construction machinery technical field, more particularly to a kind of angle-bender.
Background technology
In electric power tunnel construction, commonly using the different reinforcing bar of length difference, bending radius, reinforcing bar generally use reinforcing bar is curved
Bent machine is bent.It is a kind of conventional angle-bender shown in Fig. 1, includes the lathe 1 of cuboid shape, 1 top of lathe is set
It is equipped with scratch diskette 2, lathe 1 is internally provided with motor, and motor connect with 2 central axis of scratch diskette and drives scratch diskette 2 in level
Rotation in surface.Central pin shaft 21 is provided at the end face center of scratch diskette 2, top surface eccentric part, which is provided with, bends axis pin 22, work
1 top surface of lathe of 2 side of disk is fixed with support axis pin 23, and central pin shaft 21 bends axis pin 22 and 23 three of axis pin is supported to be formed
Force position at the three of moment reinforcement.
When using above-mentioned angle-bender, by reinforcing bar be placed on support axis pin 23, central pin shaft 21 and bend axis pin 22 it
Between, support 23 axis of axis pin and press-bending axis pin 22 are in the same side of reinforcing bar, and motor drives scratch diskette 2 to turn round, to support 23 He of axis pin
Central pin shaft 21 is force position, bends axis pin 22 and oppresses reinforcing bar to the curving close to central pin shaft 21 so that reinforcing bar around
The outer wall of central pin shaft 21 is bent, and processes bending radius.
But the bending radius that reinforcing bar is commonly used in electric power tunnel construction is larger, and what above-mentioned angle-bender was processed
The limitation of 21 outer diameter of bar bending radius acceptor center axis pin, bending radius is smaller, cannot be satisfied electric power tunnel construction to steel
The needs of muscle bending radius.For this purpose, can only be bent to reinforcing bar by manual operation, particularly with reinforcing bar length is shorter or steel
The case where muscle is relatively large in diameter needs more people to coordinate, also time-consuming and laborious to increase bending moment by tools such as reinforced bar sleeves.
Invention content
In view of the shortcomings of the prior art, the present invention provides a kind of angle-bender, its advantage is that, it is easy to process go out big bending
Radius, and it is not shorter or be relatively large in diameter and limited by reinforcing bar length, it is time saving and energy saving.
The present invention above-mentioned technical purpose technical scheme is that：
