Abstract
The utility model relates to a novel hydraulic hoop-bending machine. The novel hydraulic hoop-bending machine comprises an oil box body, a valve body and a switch swing rod. The valve body is fixedly installed on the upper surface of the oil box body, and one side of the valve body is connected with a frame and the switch swing rod is fixedly connected on the frame. A reversing swing hammer is installed on the upper side of the frame. A reversing stirring fork is installed in the front of the valve body. A tension spring is arranged at the lower end of the switch swing rod. A switch valve core, a hydraulic valve core and a reversing valve core are respectively installed in the valve body from bottom to top. The novel hydraulic hoop-bending machine has the advantages that a user can step on a small-angle pedal or a large-angle pedal to achieve different bending angles; when a small angle is bent, the user steps on the small-angle pedal, an angle-changing sliding block stirs the reversing swing hammer to strike a reversing pressing sleeve, and accordingly the reversing valve core moves backwards to achieve reversing; and when a large angle is bent, a sliding block guide rail support supports a sliding block guide rail to ensure that the angle-changing sliding block rises, a large-angle striking block stirs the reversing swing hammer to strike the reversing pressing sleeve, and accordingly the reversing valve core moves backwards to achieve reversing. The novel hydraulic hoop-bending machine facilitates learning of a green hand and making experienced people to improve production efficiency.

The utility model content
At above defective, the utility model provides a kind of feet controllable conversion bending hoop angular dimension, is convenient to new hand study, reduces workload, helps enhancing productivity, novel hydraulic hoop bender conveniently, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of novel hydraulic hoop bender comprises oil box, valve body, switch rocking bar, described oil box upper surface fixed installation valve body, and described valve body one side connects fixedly connected switch rocking bar on frame and this frame; Be positioned at the frame upside commutation pendulum is installed, the commutation shift fork is installed before the described valve body.Described switch rocking bar lower end is provided with tension spring, is positioned at valve body switch spool, hydraulic valve core, reversing valve core are installed respectively from the bottom to top; Described commutation shift fork is connected with the switch shift fork by extension spring, and the switch shift fork is by brake bar drive work.Be positioned at the frame upside slide block guide rail and slide block guide rail bearing are installed; Described angle pull bar and angle push rod and slide block guide rail bearing are hinged; Described wide-angle is foot-operated to be hinged with the angle pull bar; Described low-angle is foot-operated to be hinged with the angle push rod.Described oil cylinder is installed on the frame, and described angle slide block and wide-angle collision block are installed on the oil cylinder.
Compared with prior art, the beneficial effect of novel hydraulic hoop bender described in the utility model is: integral body, and curved different angles can be ridden and realize by stepping on the foot-operated or wide-angle of low-angle, are convenient to new hand's study and help enhancing productivity; Specifically:
(1) directly is fixed on the frame by the pendulum that will commutate, switch rocking bar, valve body, can reduces the accuracy rate that machine vibration influences the bending hoop angle;
(2) ride and realize curved different angles by stepping on the foot-operated or wide-angle of low-angle, step on during curved low-angle that low-angle is foot-operated to be stirred commutation pendulum bump commutation gland by the angle slide block and make to move behind the reversing valve core and realize commutation; Step on during curved wide-angle that wide-angle is foot-operated to be propped up slide block guide rail by the slide block guide rail bearing angle slide block is risen, stir commutation pendulum bump commutation gland by the wide-angle collision block and make to move behind the reversing valve core and realize commutation, be convenient to new hand's study and skilled worker and enhance productivity;
(3) make the reversing valve core reach realize commutation by tension spring pulling commutation shift fork, after making reversing valve core, commutation pendulum bump commutation gland moves the realization commutation, when bending hoop, foot-operated when living the not loose pin of pedal since the power of tension spring less than the tension spring of pulling commutation pendulum, thereby the excessive and motor overload work of bending hoop angle can not occur and damage situation such as motor.
