Abstract
The utility model relates to a new hydraulic tube bender, comprising a movable car body. A hydraulic oil tank and a hydraulic pump are arranged on the car body, the drive rod of the hydraulic oil tank is connected with the top bending module, a connecting plate is fixed on the hydraulic oil tank, the connecting plate is connected with a bracing plate, the top ends of two corners of the bracing plate are provided with support rollers. The utility model is characterized in that: a multistage circular arc is arranged on the support roller. The utility model uses the multistage arc support roller structure, not only the steel tubes of different diameters can be bent-made, but also the sliding friction can be changed to rolling friction, so that the power consumption is reduced greatly, and the hydraulic system with the same power can bend bigger and thicker pipelines. The utility model has the advantages of compact structure, simple arrangement of oil tube, less failure and reliable operation.
Description
Technical field
The utility model relates to a kind of metal pipe material process equipment, specifically a kind of novel hydraulic bending machine.
Background technology
Bending machine is a kind of broad-spectrum metal tube processing unit, in the installation process of electric power, boiler, chemical industry and civil buildings, often needs a kind of can the use at the construction field (site), movably bending machine.Particularly the employed pipe diameter specifications of industry such as electric power, boiler, chemical industry are a lot, tube wall is thicker, and processing is got up and bothered very much.At present the bending machine kind on the domestic market is many, generally adopts hydraulic pump and hydraulic pressure to prop up the top portion split and is provided with oil pipe and links to each other, and the hydraulic pump that has is loaded on the top of fuselage, connects bottom the hydraulic cylinder with oil pipe again.This of bending machine kind of structure makes the oil circuit of voltage supply longer, causes fluid to leak easily, and to hydraulic cylinder, its pressure has certain loss to pressure oil through oil circuit, influences the hydraulic cylinder effect.And its hydraulic system is discrete topology, and it has, and volume is big, oil pipe is complicated, carrying and use inconvenient shortcoming.The bogie wheel of existing bending machine is square in addition, has only one section circular arc on it, and it has the shortcoming that frictional resistance is big, can not bend the different-diameter pipe fitting.Therefore inventing a kind of novel bending machine is highly profitable.
Summary of the invention
Goal of the invention of the present utility model is exactly in order to solve the defective that existing product exists, a kind of novel hydraulic bending machine to be provided, and it has overcome the existing product complex structure, has used inconvenient shortcoming.
The technical solution of the utility model is achieved in that it comprises a movably car body, hydraulic oil container and hydraulic pump are housed on the car body, the drive link of hydraulic oil container is connected with the bending mould, be fixed with connecting plate on the hydraulic oil container, connecting plate is connected with fagging, bogie wheel is equipped with on the top at two angles of fagging, it is characterized in that: bogie wheel which is provided with multi-section circular arc for circular roller.Have locating hole on the described fagging, bogie wheel is fixed on the locating hole; The power unit module is housed on the described hydraulic oil container, the inside of power unit module has oil-feed tank and oil-recovery tank, oil-feed tank communicates with the oil-out of oil pump, overflow valve and Pressure gauge are housed on the oil-feed tank, the switch of solenoid control oil-feed tank and oil-recovery tank is housed on the power unit module, and oil-feed tank is connected with oil pipe respectively with oil-recovery tank.Described bogie wheel is fixed on the locating hole of fagging by latch; Described bending mould is fixed on the drive link by latch; Described connecting plate is connected with the double end pull bar.
The utility model adopts multistage arc bogie wheel structure, both can bend the steel pipe of different-diameter, becomes sliding friction again and is rolling friction, greatly reduces power consumption, and making can crooked bigger thicker pipeline with the power hydraulic system.The utility model adopts the integrated hydraulic system, and it has compact conformation, oil pipe is arranged simple, few, the reliable advantage of fault.

The specific embodiment
As shown in Figure 1, the utility model comprises a movably car body 10, hydraulic oil container 9 and hydraulic pump 12 are housed on the car body 10, the drive link 7 of hydraulic jack 21 is connected with bending mould 4, be fixed with connecting plate 8 on the hydraulic jack 21, connecting plate 8 is connected with fagging 1, and bogie wheel 2 is equipped with on the top at two angles of fagging 1, bogie wheel 2 is a round roller, which is provided with multi-section circular arc 6.Have locating hole 13 on the described fagging 1, bogie wheel 2 is fixed on the locating hole 13; As shown in Figure 3, Figure 4, on the described hydraulic oil container 9 power unit module 14 is housed, the inside of power unit module 14 has oil-feed tank 15 and oil-recovery tank 16, oil-feed tank 15 communicates with the oil-out of oil pump 17, overflow valve 18 and Pressure gauge 19 are housed on the oil-feed tank 15, the Kai Heguan of magnetic valve 20 control oil-feed tanks and oil-recovery tank is housed on the power unit module 14, and oil-feed tank is connected with oil pipe respectively with oil-recovery tank.Described bogie wheel 2 is fixed on the locating hole of fagging 1 by latch 3; Described bending mould 4 is fixed on the drive link 7 by latch 5; Described connecting plate 8 is connected with double end pull bar 11.
As shown in Figure 2, during work with the required Metal pipe strap that bends in the groove of bending mould 4, primer fluid pressing system then, drive link 7 will promote bending mould 4 and move forward, thereby metal tube is pushed up on the bogie wheel 2 that the top at two angles of fagging 1 is equipped with, and make pipe bending by extruding, because bogie wheel 2 is circular roller, therefore frictional resistance is very little, and power consumption is very little, can bend the pipeline of heavy wall.Owing on the bogie wheel 2 multi-section circular arc 6 is arranged, therefore can bend the metal tube of different big or small calibers easily.The utility model adopts integrated power unit module 14, and it has compact conformation, oil pipe is arranged simple, few, the reliable advantage of fault.
