End is respectively equipped with fixed platform, and fixed platform is equipped with clamping hook.
Using above-mentioned steel pipe bar folder, the bending of steel pipe is mainly formed by the punching press of hydraulic device, it is this at
Type mode, inflection point are usually located at one, when being bent in an arc shape to whole steel pipe, are bent by above-mentioned bending machine
It is difficult to compare, and has much room for improvement.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of steel tube bending machine, it is integral curved curved with steel pipe
Roll over more convenient advantage.
To achieve the above object, the present invention provides the following technical scheme that
A kind of steel tube bending machine, including rack, there are two delivery wheel, the rotation axis of two delivery wheels for rotation connection in the rack
Line is arranged in parallel, and each delivery wheel is circumferentially equipped with annular groove, and two annular grooves are correspondingly arranged, are additionally provided in the rack
The actuator rotate in same direction for two delivery wheels of corresponding driving；Connect in the rack along perpendicular to two delivery wheels
The direction sliding of line is connected with slip base, and the hydraulic cylinder for adjusting the slip base position is additionally provided in the rack；Institute
It states and is also rotatably connected to abutting wheel on slip base, the pivot center for pushing against wheel is parallel with the pivot center of the delivery wheel,
The abutting wheel is additionally provided on the slip base for pushing against steel pipe in the annular groove of delivery wheel for driving the abutting
Wheel and the counter-rotational driving motor of the delivery wheel.
Through the above technical solutions, when continuously being bent using above-mentioned bending machine to steel pipe, when the bending of low-angle,
Control hydraulic cylinder drives slip base mobile first, so that the lower end surface for pushing against wheel is lower than the upper surface of annular groove, then starting driving
Part and driving cylinder, so that delivery wheel and abutting wheel rotation, then by steel pipe to be bent along charging one end of delivery wheel
Be put into above delivery wheel so that steel pipe is located in annular groove, the rotation of the delivery wheel first contacted steel pipe can be carried through to
Bearing up pulley lower section and the annular groove for contacting at the latter delivery wheel, the rotation of the delivery wheel contacted afterwards can be by steel pipe along its rotation side
To passing through from the upper side, rotated while pushing against wheel and delivery wheel, so that bending machine is more stable to the transport and bending of steel pipe.
When needing to carry out the bending of wide-angle to steel pipe, steel pipe is placed in above two delivery wheels first, steel pipe is located at two simultaneously
In the annular groove of a delivery wheel, then hydraulic cylinder drives slip base mobile, takes turns towards movement between two delivery wheels simultaneously so that contradicting
Steel pipe is bent, then starts actuator and driving motor simultaneously again, steel is driven by delivery wheel and the rotation for pushing against wheel
The movement of pipe, so that steel pipe is bent along bending angle instantly.By pushing against the cooperation of wheel and delivery wheel to steel
Pipe is bent, and whole bending can be carried out to steel pipe, so that the entirety bending of steel pipe is more convenient.
Further, the delivery wheel includes main shaft, the chassis being fixedly connected on main shaft, coaxial sleeve on main shaft
Telophragma and coaxial sleeve are set to the block plate that telophragma deviates from chassis side, and the diameter of the telophragma is less than block plate, chassis is set
It sets, is also threaded on the main shaft for compressing block plate in the locking nut on telophragma.
Through the above technical solutions, multiple and different spare telophragmas can be set, when needing to bend round tube,
The telophragma for being equipped with the half slot being bonded for round tube lateral wall can be used, the two sides that chassis and block plate can contact at round tube carry out
Positioning；When needing to bend various sizes of square tube, the corresponding telophragma of size selection that can correspond to square tube is bent, and is made
The use for obtaining steel tube bending machine is more flexible.
Further, the abutting wheel has been uniformly distributed circumferentially several anti-skid chequers.
Through the above technical solutions, anti-skid chequer is parallel to the axis setting for pushing against wheel, anti-skid chequer can be convex ribs, can also be with
It is groove, reinforces pushing against the frictional force of wheel with steel pipe by anti-skid chequer, so that it is more stable to the transport of steel pipe to push against wheel.In addition
It pushes against and takes turns setting cylindrical, when the more actual steel pipe of delivery wheel is adjusted, pushing against wheel can not adjust and always
Steel pipe side is pushed against, so that steel tube bending machine is more convenient to use.
Further, the rack offers cavity along two delivery wheel line directions, in the cavity there are two slidings
Mounting base, the glide direction of two mounting bases are parallel to the line direction setting of two delivery wheels；Two delivery wheels are uniform
One correspondence is rotationally connected in the mounting base, and the adjusting group for adjusting the mounting base position is additionally provided in the rack
Part.

Between distance be adjusted, allow delivery wheel it is more actual using carry out position adjusting so that bending machine makes
With more flexible.
Further, the adjusting component includes the reverse-flighted screw being rotationally connected in rack, is set to the two-way spiral shell
The adjustment portion of bar axial direction one end, the reverse-flighted screw include forward screw thread section and reverse thread section, two mounting base difference
Correspondence is threadedly connected in forward screw thread section and reverse thread section.
Through the above technical solutions, can be rotated by adjustment portion when needing to adjust the distance between two delivery wheels
Reverse-flighted screw, so that two delivery wheels are close or separate simultaneously simultaneously, and forward screw thread section is identical with the screw pitch of reverse thread section,
So that two delivery wheels keep identical movement speed, pushed against always so that pushing against wheel in the position of two delivery wheel middles
It sets, so that steel pipe two sides in bending are more uniformly stressed, so that whole bending more uniform stabilization.
Further, the cavity is provided with sliding rail along mounting base glide direction, and correspondence offers confession in the mounting base
The sliding slot of the sliding rail sliding.
Through the above technical solutions, setting sliding rail and sliding slot, by the guiding of sliding rail and sliding slot, so that the adjusting of mounting base
Movement is more stable.
Further, one end of the reverse-flighted screw axial direction is provided with positioning gear, and sliding connection is useful in the rack
The latch that positioning gear side wall is locked described in clamping, one end of the remotely located gear of latch is provided with for pushing against
The latch is in the limit assembly on the positioning gear.
Through the above technical solutions, by the abutting limit of positioning gear and latch, when steel tube bending machine operation, latch
It can push against and be positioned on positioning gear, to reduce since the vibration that equipment is transported causes reverse-flighted screw to deflect
Situation, so that the position fixation of delivery wheel is more stable in mounting base, so that the bending effect of steel tube bending machine is more steady
It is fixed.
