Description
Technical field
The present invention relates to mechanical bend pipe field, specifically is a kind of bending mechanism of double shaft bi-directional pipe bender.
Background technology
Present mechanical bend pipe industry adopts all that single head is unidirectional to carry out Bending Processing technology along bending die, can only adopt when needing a plurality of different overbending direction of bending on a tubing changes the material method and solves, and therefore general bending method and bending machine can only be confined to the bending of an aspect.Fail to solve always and can only adopt manual bending technique operation for two solid figure bendings of need bending, seriously restricted the technical development in bend pipe field with the superimposed layer aspect.
Summary of the invention
The bending mechanism that the purpose of this invention is to provide a kind of double shaft bi-directional pipe bender, complicated three-dimensional shape pipe fitting that can a plurality of lamination aspects of the multiple shape of bending, not only reduce labor intensity greatly, forming quality also is improved, and particularly the R circular arc in the bending knee of pipe fitting is smooth tall and straight full.
Technical scheme of the present invention is as follows:
The bending mechanism of double shaft bi-directional pipe bender, it is characterized in that: include bearing, the upper end of bearing is rotatablely equipped with swiveling gear, swiveling gear drives by the turning motor that has gear, the upper surface of swiveling gear is slidingly fitted with the swiveling head support, be slidingly fitted with in the swiveling head support to part on the left side and close slide block, part on the right side and close slide block, part on the left side and close slide block, part on the right side to close and be fixed with left centration axis, right centration axis in the slide block respectively, the upper end of left centration axis, right centration axis is equipped with bend pipe mould; Part on the left side and close slide block, the swiveling head chute is arranged in the other end of swiveling head support, be installed with the swiveling head driving lever that is inserted in the described swiveling head chute on the swiveling gear by being fixed in deciliter air cylinder driven in the swiveling head support; The below of bearing is installed with left bearing pin lift cylinder, right bearing pin lift cylinder, the piston rod front end of left side bearing pin lift cylinder, right bearing pin lift cylinder is fixedly connected with left bearing pin, right bearing pin, and left bearing pin, right bearing pin are driven to move up by cylinder and can be inserted into respectively in left centration axis or the right centration axis axis hole.
Described bearing upper end is set with bearing, and the outer fixed cover of bearing is equipped with swiveling gear.
Left centration axis of the present invention, right centration axis are installed on respectively to part on the left side and close slide block, part on the right side and close slide block, the swiveling head support can be free to slide or rotate on the swiveling gear upper surface, a left side centration axis, right centration axis are rotated left bearing pin, right bearing pin are inserted in the axis hole of left centration axis, right centration axis as pivot, and will have the swiveling head driving lever to drive could to rotate.The swiveling head driving lever is fixed on the swiveling gear, because the centre of gyration of swiveling gear is the center line of bearing, and the centre of gyration of swiveling head support is left centration axis or right centration axis, the two decentraction is so the swiveling head driving lever can slide in the swiveling head chute of swiveling head support and does Geneva mechanism motion when transmitting torque.
Bending course of action of the present invention is: under deciliter cylinder action, mould on a left side centration axis and the right centration axis closes up and clamps pipe fitting to be curved, left side bearing pin is promoted and is inserted in the axis hole of left centration axis by left bearing pin lift cylinder, makes left centration axis that pivot arranged; To drive the swiveling head support be the center rotation with left centration axis by being installed in swiveling head driving lever on the swiveling gear during around the bearing rotation under turning motor drives when swiveling gear, right centration axis with and the upper end bend pipe mould also with left centration axis with and the bend pipe mould of upper end be the center rotation, thereby finish the work of bending for the first time.
After the bending for the first time, a left side centration axis and bend pipe mould be homing and move forward and the next part for the treatment of bending enters in the middle of two bend pipe moulds by the feeding action part of bending immediately, right then bearing pin promotes in the axis hole that inserts right centration axis by right bearing pin lift cylinder and makes right centration axis that pivot arranged, left bearing pin withdraws from the axis hole of left locating shaft by left bearing pin lift cylinder pulling simultaneously, when swiveling gear drives the also reverse rotation of swiveling head support by the swiveling head driving lever during reverse rotation under motor-driven, be installed on the swiveling head support left centration axis with and the bend pipe mould of upper end also just do reverse rotation around right centration axis and its bend pipe mould, thereby finish the reciprocal bending work second time.
Pivot during bending for the first time is left centration axis, for the second time the pivot during inverse bending is right centration axis, and the pivot that the swiveling gear of bending power torque is provided is changeless, the transmission of power torque is to realize by the driving lever and being slidingly matched of swiveling head chute that are fixed on the swiveling gear, and the conversion of the pivot of forward and inverse bending spurs left bearing pin, right bearing pin (promptly plugging Xiao's action) realization respectively by left bearing pin lift cylinder, right bearing pin lift cylinder.
