Description
Technical field
The present invention relates to a kind of swan neck system, specifically refer to a kind of hydraulic pipe bending device.
Background technology
Hydraulic pipe bender is to drive linkage to carry out bend pipe by hydraulic jack, be divided into oil cylinder ejection bending type and oil cylinder and drive two kinds of chain-types, this type of bending machine advantage is that process velocity is very fast, be applicable to batch production, shortcoming is less stable, maintenance cost is higher, and often occurs the phenomenon of hydraulic jack leakage of oil, easily occurs the excessive less pipe fitting processing phenomenon not up to standard that causes of the impaired or thrust of pipe fitting that causes of thrust when Hydraulic Cylinder; And mechanical pipe bender is to carry out bend pipe by mechanical gear and lever principle, be divided into two kinds of electric pipe bender and hand lever pipe bendeies, this type of angle pipe equipment advantage is simple to operate, maintaining is convenient and expense is low, service life of a machine is long, and machining accuracy is high, and equipment is small and exquisite removable, shortcoming is that process velocity is slower, and efficiency is on the low side.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic pipe bending device, guarantee the stability of hydraulic cylinder when propelling or rollback, reduce the maintenance cost of device.
Object of the present invention is achieved through the following technical solutions:
A kind of hydraulic pipe bending device, comprise support, bend pipe post and boss are installed on described support, boss is arranged on a side of bend pipe post, hydraulic cylinder is arranged on boss, on the output of described hydraulic cylinder, connecting rod is installed, the end of connecting rod is connected with pushing plate, on described support, guide rail is installed, pushing plate is slidably arranged on guide rail, on described pushing plate, be provided with U-lag, described bend pipe post is provided with square-section over against a side of hydraulic cylinder, middle and upper part in square-section is provided with fixed block, both sides up and down at fixed block are respectively arranged with limiting plate, limiting plate is placed in the outside, end of U-lag, the end of described limiting plate has through hole, gag lever post with nut is installed in through hole, between two limiting plates, bent tube holder is installed, on bent tube holder, have deep-slotted chip breaker.When the present invention works, pipe fitting is fitted with U-lag after passing the gap between two limiting plates, hydraulic cylinder drivening rod moves pushing plate on guide rail, because bend pipe post maintains static, the stressed opposite direction in two ends of pipe fitting, therefore there is deformation in pipe fitting on U-lag, completes bend pipe operation; The gag lever post with nut arranging on limiting plate, pipe fitting can be fixed, avoid the stressed rear generation of pipe fitting when carrying out bend pipe be offset and then cause pipe fitting flexibility not up to standard, in process, U-lag can be fitted completely with pipe fitting, the each several part that has guaranteed pipe fitting when hydraulic cylinder advances is stressed evenly, reduces the processing loss of pipe fitting; The present invention is simple in structure, pushing plate is slidably arranged on guide rail, can guarantee the stable movement of pushing plate, the how with bolts or movable connection method that slides and arrange of the overall structure of device, conveniently fast disassembling is installed, and has effectively reduced the maintenance cost of device.
Also comprise locating piece, described locating piece is fixedly mounted on support, on locating piece, be provided with locating hole, described connecting rod reduces gradually along axis direction diameter from left to right, connecting rod is connected with pushing plate through locating hole, interconnective pressure sensor and controller are installed on the inwall of locating hole, and controller is connected with hydraulic cylinder.When hydraulic cylinder output drivening rod moves, often occur that connecting rod promotes too quickly, and then cause pushing plate by pipe fitting curved transitions, cause larger loss; The locating piece arranging coordinates with connecting rod, when the distance moving when pushing plate is just worked into required flexibility by pipe fitting, connecting rod knock is to locating hole, and the pressure sensor direct signal in locating hole is transferred to controller, controller is adjusted hydraulic cylinder, makes it out of service; Controller is regulator solution cylinder pressure again, makes pushing plate rollback, machines.
The bottom of described limiting plate is provided with projection, in the both sides up and down of fixed block, is provided with dovetail groove, projection and dovetail groove engagement, and described limiting plate is bolted on dovetail groove.The engagement of limiting plate and fixed block, avoids pipe fitting to affect pipe fitting and clamp fastening stability adding the interaction force producing between man-hour and limiting plate, gag lever post and bent tube holder.
In described U-lag, rubber blanket is installed.During bend pipe, mutually stressed between U-lag and pipe fitting, for avoiding pipe fitting surface impaired, the effect that rubber blanket can play cushioning effect power is installed in U-lag.
Described bent tube holder is connected with limiting plate bolt.Because the degree of crook that different pipe fittings are processed is inconsistent, size and the radian of the deep-slotted chip breaker of offering on bent tube holder are also not quite similar, and bent tube holder is connected with limiting plate bolt, can realize the quick-replaceable of bent tube holder, increase the practicality of device.
The present invention compared with prior art, has following advantage and beneficial effect:
1, a kind of hydraulic pipe bending device of the present invention, the present invention is simple in structure, pushing plate is slidably arranged on guide rail, can guarantee the stable movement of pushing plate, the how with bolts or movable connection method of the setting of sliding of the overall structure of device, conveniently fast disassembling is installed, and has effectively reduced the maintenance cost of device;
2, a kind of hydraulic pipe bending device of the present invention, when hydraulic cylinder output drivening rod moves, can effectively avoid occurring that connecting rod promotes too quickly, reduces pushing plate pipe fitting curved transitions is caused to larger loss;
3, a kind of hydraulic pipe bending device of the present invention, because the degree of crook that different pipe fittings are processed is inconsistent, size and the radian of the deep-slotted chip breaker of offering on bent tube holder are also not quite similar, and bent tube holder is connected with limiting plate bolt, can realize the quick-replaceable of bent tube holder, increase the practicality of device.
