Description
Technical field
The present invention relates to a kind of bending press of pipeline, especially a kind of bending press for square tube.
Background technology
Square tube is a kind of cast of square body, is mainly used in the projects such as building, machine-building and iron and steel construction.Square tube is in the process of using as run into turning, needs an external angled square tube of tool, and this arc square pipe complex manufacturing technology, cost of manufacture is high, has improved the production cost of enterprise; In addition, between arc square tube and square tube, be connected the annexation that adopts welding, this annexation easily produces the service life of gap restriction square tube in the process of using, and has brought bad impact to the use of square tube.
Summary of the invention
The object of the invention is provides a kind of easy to use in order to solve the deficiency of above-mentioned technology, and cost of manufacture is low, the square tube bending press that can directly straight type square tube be bent.
In order to achieve the above object, a kind of square tube bending press that the present invention is designed, it comprises base, motor, rotating shaft, connecting rod and hold-down mechanism; Described base is provided with discharging opening, and described rotating shaft is arranged on base by the support of both sides, and one end of rotating shaft is connected with motor by chain, and rotating shaft is provided with rotating disk, and rotating disk is provided with eccentric shaft; Connecting rod is arranged on base by bracing frame, and one end of connecting rod is connected with eccentric shaft, and the other end is connected with hold-down mechanism; Described hold-down mechanism comprises movable disk, connecting axle, motion bar and pressing mold, described motion bar comprises quarter butt, stock and movable axis, being connected by movable axis with stock of quarter butt, described movable disk is arranged on the side of base, the bottom of movable disk is provided with pressing mold, pressing mold is corresponding with the top of the discharging opening of base, and the both sides of movable disk are connected with the quarter butt of motion bar by connecting axle, and the other end of stock is arranged on base by connecting axle; Two described stocks are provided with pressing mold in a side of discharging opening.
In such scheme, on the sidewall of described base, be also provided with bore reduction means, it comprises fixed mount, mould, fixture and displacement disc, described mould is arranged on fixed mount, and the bilateral symmetry of mould is provided with track, and track is provided with fixture, described rotating shaft is provided with displacement disc, displacement disc is provided with two fixed axis, and two fixed axis are on same straight line, and fixture is connected with fixed axis respectively.
As preferably, between two described movable axis, be provided with spring, can help the active homing of movable axis.
The resulting a kind of square tube bending press of the present invention, square tube is exported from discharging opening, under the effect of motor, connecting rod drives movable disk up and down, when connecting rod drives movable disk to move upward, the motion bar being connected with movable disk is outwards opened, and 3 pressing molds are all expanded outwardly; When connecting rod drives movable disk to move downward, the motion bar being connected with movable disk inwardly tightens, and 3 pressing molds are all compressed to discharging opening; Therefore, in the discharging process of square tube, along with one rise and one drop of movable disk, make three faces of square tube in the process of discharging compacted, thereby force square tube crooked towards not compacted face.By the good square tube mouthpiece cover of bending, on mould, under the effect of motor, displacement disc drives fixture to the motion of mould direction, thereby the mouth of pipe of square tube is compressed, and has facilitated being connected between square tube after being bent and other square tubes.
This structure has reasonable in design, easy to use, and square tube bending effect is good, the crooked efficiency advantages of higher of square tube.
