Description
Technical field
The present invention relates to bending machine, specifically push mode reversible deformation hydraulic cold bending forming machine.
Background technology
At oil, chemical industry, in the industry engineering constructions such as hot-water heating, cold bending making is one basic working procedure wherein, although this procedure seems simple, but the making quality of cold bending directly has influence on the quality of whole engineering, the cold bending production method that we commonly used in the past uses single head or double end hydraulic pipe bender to carry out bending making by canoe, this clod wash mode, pipe is difficult to accurate control bending horizontal concentricity in process, the stress distribution that pipe cross section receives is uneven, circular arc place distortion serious (ellipse), outside circular arc, tube wall thickness is excessive, wrinkling inside circular arc (waveform wrinkle) etc., product defect rate is high, cause the significant wastage of raw material and manpower.Equipment investment cost is high in addition, complicated operation.
Summary of the invention
The object of the present invention is to provide push mode reversible deformation hydraulic cold bending forming machine, simple to operate, efficiency is high, horizontal concentricity accurate positioning, effective controlling distortion, adapts to the making needs of small-bore cold bending in engineering construction.
In order to reach above-mentioned purpose, present invention employs following technical scheme, push mode reversible deformation hydraulic cold bending forming machine, comprise workbench, reversible deformation jacking head, positioning roller, the axis of described workbench is provided with the reversible deformation jacking head that can move forward and backward, and axis bilateral symmetry is provided with two positioning rollers, and the residing on the table position of positioning roller is positioned at the both sides, front of reversible deformation jacking head.
Described reversible deformation jacking back-end of machine head is hinged with hydraulic drive bar by connecting axle, and hydraulic drive bar is connecting fluid hydraulic driver again.
The top of described connecting axle is fixed with rule.
The dragging track that described reversible deformation jacking head is arranged by bottom moves forward and backward on the table.
Described positioning roller is fixing on the table by positioning roller fixed station.
Described positioning roller fixed station and positioning roller all offer corresponding spacing hole, is fixed through limit shaft in spacing hole.
The side that described positioning roller fixed station is being positioned at reversible deformation jacking heading is provided with horizontal location bracket, is then provided with reinforcement gusset at opposite side.
Described positioning roller groove center line and reversible deformation jacking head front end arc groove center line at same level line, and exceed horizontal location pallet top, and the distance exceeded is by the half of curved tube outer diameter.
Compared to prior art, the present invention has following beneficial effect:
Use positioning roller and horizontal location bracket, pipe is fixed on horizontal level to ensure the levelness of pipe, the anti-deformation arc-shaped groove of pushing tow head front end and pipe are coincide after being close to, jacking head makes tube bending.The positioning roller of this new-type push mode reversible deformation hydraulic cold bending forming machine and horizontal location bracket solve the problem that pipe horizontal concentricity in BENDING PROCESS is in the past difficult to accurately control.Because the radian size of positioning roller groove and head front end anti-deformation arc-shaped groove is consistent with the external diameter of pipe bending, ensure that the stress equilibrium distribution in the whole BENDING PROCESS of pipe suffered by cross-sectional direction, efficiently solve the circular arc place distortion serious (ellipse) in the past caused due to distribution of force inequality on pipe cross section, outside tube wall thickness is excessive, inner side is wrinkling problems such as (waveform wrinkles).In addition, supporting positioning roller and the head having different specification size of push mode reversible deformation hydraulic cold bending forming machine, can make the cold bending of different size, good construction adaptability.
The present invention is applicable to bend for oil under cold condition, chemical industry, small-diameter thick-walled (pipe thickness >=7mm) the fluid conveying welded pipe of the industries such as hot-water heating, electric welded steel pipe and general service steel pipe, specifically utilize the push mode reversible deformation hydraulic cold bending forming machine developed voluntarily, in the manufacturing process of cold bending, some resistance when pipe bends is offset by the pushing tow of head front end deep-slotted chip breaker and thruster, improve the stress distribution on pipe cross section, reduce tube wall thickness outside pipe, avoid being out of shape concentration of local, and the bend pipe of different size is made by adjustment equipment component, efficient and specification ground carries out the making of cold bending.
