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 drives linkage to carry out bend pipe by hydraulic jack, oil cylinder ejection bending type and oil cylinder is divided into drive chain-type two kinds, 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 that phenomenon not up to standard processed by the excessive less pipe fitting that causes of the impaired or thrust of pipe fitting that causes of thrust when Hydraulic Cylinder; And mechanical pipe bender carries out bend pipe by mechanical gear and lever principle, be divided into electric pipe bender and hand lever pipe bender two kinds, 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 comparatively slow, 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, ensure 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 the bracket, boss is arranged on the side of bend pipe post, hydraulic cylinder is arranged on boss, the output of described hydraulic cylinder is provided with connecting rod, the end of connecting rod is connected with pushing plate, on the bracket guide rail is installed, pushing plate is slidably arranged on guide rail, described pushing plate is provided with U-lag, described bend pipe post is just provided with square-section to the side of hydraulic cylinder, the middle and upper part of square-section is provided with fixed block, limiting plate is respectively arranged with in the both sides up and down of fixed block, limiting plate is placed in outside the end of U-lag, the end of described limiting plate has through hole, the gag lever post of band nut is installed in through hole, between two limiting plates, bent tube holder is installed, bent tube holder has deep-slotted chip breaker.When the present invention works, pipe fitting is fitted with U-lag through behind the gap two limiting plates, hydraulic cylinder drivening rod makes pushing plate move on guide rail, because bend pipe post maintains static, the two ends Impact direction of pipe fitting is contrary, therefore there is deformation in pipe fitting on U-lag, namely completes bend pipe operation; The gag lever post of the band nut that limiting plate is arranged, pipe fitting can be fixed, avoid the stressed rear generation skew of the pipe fitting when carrying out bend pipe and then cause pipe fitting flexibility not up to standard, in process, U-lag can be fitted completely with pipe fitting, ensure that each several part uniform force of the pipe fitting when hydraulic cylinder advances, reduce the processing loss of pipe fitting; Structure of the present invention is simple, pushing plate is slidably arranged on guide rail, can ensure the stable movement of pushing plate, and how with bolts the overall structure of device is or slide the movable connection method arranged, conveniently fast disassembling is installed, and significantly reduces the maintenance cost of device.

The bottom of described limiting plate is provided with projection, and the both sides up and down of fixed block are provided with dovetail groove, and projection engages with dovetail groove, and described limiting plate is bolted on dovetail groove.Limiting plate engages with fixed block, avoids pipe fitting to affect the stability of pipe fitting clamping fastener at the interaction force adding man-hour and produce between 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 tube 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.The degree of crook processed due to different pipe fitting is inconsistent, and size and the radian of the deep-slotted chip breaker offered 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, increases 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, structure of the present invention is simple, pushing plate is slidably arranged on guide rail, the stable movement of pushing plate can be ensured, how with bolts the overall structure of device is or slide the movable connection method arranged, conveniently fast disassembling is installed, and significantly reduces the maintenance cost of device;
2, a kind of hydraulic pipe bending device of the present invention, when hydraulic cylinder output drivening rod moves, effectively can avoid occurring that connecting rod promotes too quickly, reduce pushing plate and pipe fitting curved transitions is caused larger loss;
3, a kind of hydraulic pipe bending device of the present invention, the degree of crook processed due to different pipe fitting is inconsistent, and size and the radian of the deep-slotted chip breaker offered on bent tube holder are also not quite similar, and bent tube holder is connected with limiting plate bolt, the quick-replaceable of bent tube holder can be realized, increase the practicality of device.
