Description
Technical field
The utility model provides a kind of pipe processing equipment, particularly relates to a kind of steel pipe channelling machine.
Background technology
In the pipeline installation process, the adjunction of pipeline enclosure generally adopts two semicircle fasteners to block in the groove of two pipe ends, makes the pipe adjunction, like this need be at the end of pipe roll extrusion groove.Chinese patent CN2404609Y discloses a kind of steel pipe channelling machine, is made of framework, worm screw combination, screw mandrel combination, roll extrusion combination, spindle combinations, universal joint, connecting rod guide rail, and dial is all arranged on worm screw and the screw mandrel, is used to control the degree of depth of roll extrusion groove.Because the pinch roller of this channelling machine can not accurately be aimed at the groove of knurled wheel, therefore can't change, so can only roll the groove of a kind of specification, shape, the scope of application is little; And Chinese patent CN2348964 discloses a kind of steel pipe channelling machine, form by frame, motor, decelerator, driving shaft, manual pump, hydraulic cylinder, pinch roller and hydraulic cylinder leg, on hydraulic cylinder leg, control the degree of depth of roll extrusion groove by the cushion block of thickness in selecting not, inconvenient operation and cushion block are easily lost, its main shaft can not arbitrarily be changed, can only process a kind of groove of specification, the scope of application is little, and manual pump separates with hydraulic cylinder, connect with pressure piping between them, volume is big, and reliability reduces.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of oil pump and hydraulic cylinder to be integrated, and pinch roller can make things convenient for aims at the knurled wheel groove exactly, and volume is little, and the reliability height is suitable for the steel pipe channelling machine of processing plurality of specifications, shape, depth groove.
The utility model steel pipe channelling machine comprises by foot rest, the platform that cooperates with foot rest is arranged on the frame mechanism that the framework on the platform is formed, the actuating unit of being made up of motor, reduction box, the main shaft that is connected with reduction box and outer cover, hydraulic mechanism, pressing wheel mechanism and positioning disk mechanism.Wherein, main shaft is used for supporting pipes and rotates pipe; Hydraulic mechanism is the hydraulic cylinder combination that oil pump and oil cylinder are integrated, be installed in frame roof with screw, it comprises pump seat, is arranged on fuel tank and oil cylinder on the pump seat, the piston that cooperates with oil cylinder, be positioned at the back-moving spring that oil cylinder cooperates with piston, be arranged on the installing ring and the ring washer of piston lower end, with the oil pump that the piston upper end is connected, the handle that is connected with oil pump, valve seat with fuel tank and oil cylinder upper end cooperate is installed in pressure-relief valve and safety valve on the valve seat; Pressing wheel mechanism comprises the slide that is fixed on the framework, be fixed on the slide pinch roller frame, be installed in the wheel pressing shaft on the pinch roller frame, be installed in the pinch roller on the wheel pressing shaft, be installed on the main shaft and have the knurled wheel of groove, and pinch roller is to the centering guiding mechanism of knurled wheel groove, slide is provided with two rectangular channels, be used for mounting guide rail, and be fixed on the framework by the guide rail screw, slide is connected with piston with ring washer by installing ring.The centering guiding mechanism is fixed on the slide and the centering that is connected with pinch roller frame adjustment bolt composition by by being bolted to the ring flange on the slide by ring flange.When needs are processed the groove of all size and shape, can change pinch roller and knurled wheel, and adjust the groove of pinch roller centering knurled wheel, the method of adjusting is, at first unscrew two bolts, rotate the adjustment bolt then and make pinch roller frame move fastening bolt after finishing to the left or to the right; Positioning disk mechanism comprises a piece that is installed on the slide, is installed in the positioning disk on the piece.Positioning disk is marked with the steel pipe specification limit, and be carved be arranged on slide on the detent that matches of locking ball, be used for the lock in place dish.Steel pipe specification limit correspondence on the positioning disk different axial lengths, after slide touches the boss of framework downwards during work, slide just no longer moves down, thereby realizes the purpose of control gash depth, can select to process the pipe of different size and the degree of depth of selecting to process groove by positioning disk.
The operation principle of the utility model steel pipe channelling machine is, before the slot rolling, diameter according to pipe, wall thickness is adjusted positioning disk, processed pipe is contained on the main shaft, shut pressure-relief valve, shake the oil pump handle and make piston promote slide downwards, related pinch roller frame, pinch roller moves down together, opening power when pinch roller just touches tube surface, motor rotates, processed pipe rotates thereupon, continues to shake oil pump then and just can extrude groove, has just reached the degree of depth of groove when positioning disk touches the framework boss, open pressure-relief valve, because the effect of back-moving spring makes the related slide of piston, pinch roller moves up, and shuts power supply, takes off pipe.
The advantage of the utility model steel pipe channelling machine is that oil pump and hydraulic cylinder are integrated, and has reduced pressure piping and joint, the reliability height.Owing to be provided with centering guiding mechanism and the positioning disk of pinch roller, can the pipe processing all size of all size, the groove of shape have been solved simultaneously and adjust the problem that cushion block is lost easily in the prior art to the knurled wheel groove.
