-The metal pipe of the various bores of 50mm.
The utility model content
The purpose of this utility model is: provide a kind of manual tube bender without power and energy, with the needs of the bending metal pipe that satisfies pincers worker, pipeliner or mechanic.
The technical scheme of the utility model technical solution problem is: manual tube bender comprises support, swan neck system and guide-localization mechanism, described support is formed with trip bolt is fastening by top board, left side plate and base plate, described swan neck system comprises compacting screw rod, capstan, secondary driving wheel, driving shaft and ring-shaped handle, and described guide-localization mechanism comprises U-shaped seat, backstay and chute.Described compacting screw rod passes the top board of support vertically downward and the U-shaped seat under top board constitutes rotatable flexible connection.The side plate upper lateral of described U-shaped seat has been fixed a backstay, and the two ends of backstay are passed in the chute of the left side plate central authorities that stretch into support behind the side plate of U-shaped seat respectively, so backstay can move up and down along chute synchronously with the U-shaped seat.Between two side plates of the bottom of U-shaped seat capstan is set, the wheel shaft and the driving shaft of capstan are fixed with pin, and driving shaft becomes to flexibly connect with the side plate of U-shaped seat, and the outer end of driving shaft is provided with a ring-shaped handle.
Two secondary driving wheels are set in the bottom of support side plate, the axle center of described secondary driving wheel is installed with wheel shaft, wheel shaft and secondary driving wheel are fixed with pin key, and the wheel shaft two ends are inserted in the axis hole of support left side plate, and the end that wheel shaft stretches out behind the axis hole flexibly connects with R shape pin insertion back formation.
Be provided with and suppress the screwed hole that screw rod cooperates in the top board central authorities of described support, be provided with chute with baseplate vertical direction in support left side plate central authorities, the chute left and right sides is provided with reinforcement.On the base plate of support, be provided with two screw is installed, the top board of support, it is fixedly connected all to be provided with trip bolt between left side plate and base plate are mutual.
Major and minor guide wheel of the present utility model can freely be changed, therefore can bend the metal pipe of the following various bores of diameter 50mm, can be rated as practical and convenient, the quality of the metal pipe that it bends is much better more than the manual quality that bends, and the radian of pipe bending is elegant in appearance, can reach designing requirement.It is that pincers worker, pipeliner, mechanician and some love are done one of standing instrument of repair family.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Each title and mark among the figure: 1. the compacting screw rod, 2. top board, 3.U shape seat, 4. backstay, 5. capstan, 6. chute, 7. reinforcement, 8. wheel shaft, 9. side plate, 10. base plate, 11. secondary driving wheels, 12. are installed screws, 13.R shape pin, 14. driving shafts, 15. ring-shaped handles, 16. trip bolts.
The specific embodiment
As shown in Figure 1, the utility model is one of standing instrument of pincers worker or mechanician.It comprises support, swan neck system and guide-localization mechanism, constitute support by top board 2, left side plate 9 and base plate 10, the swan neck system that comprises compacting screw rod 1, capstan 5, secondary driving wheel 11, driving shaft 14 and ring-shaped handle 15 is set, guide locating device provided U-shaped seat 3, backstay 4 and the chute of using during bend pipe 6 of comprising on support.Screwed hole and U-shaped seat 3 that described compacting screw rod 1 passes seat top plate 2 and top board 2 central authorities constitute rotatable flexible connection, the side plate upper lateral of described U-shaped seat 3 has been fixed a backstay 4, the two ends of backstay 4 are passed in the chute 6 in the middle of the left side plate 9 that stretches into support behind the side plate of U-shaped seat 3 respectively, so backstay 4 can move up and down along chute 6 under compacting screw rod 1 drives.In the bottom of U-shaped seat 3 capstan 5 is set, the wheel shaft of capstan 5 is that driving shaft 14 usefulness pins are fixed, and driving shaft 14 constitutes flexible connection with the side plate of U-shaped seat 3, and the outer end of driving shaft 14 is provided with a ring-shaped handle 15.Bending machine support bottom is provided with two secondary driving wheels 11, its axle center is installed with wheel shaft 8, wheel shaft 8 and two secondary driving wheel 11 usefulness pin keies are fixed, wheel shaft 8 two ends hold in the axis hole of support left side plate 9, and wheel shaft 8 stretches out on the left side plate 9 promptly to form after insert with R shape pin 13 end behind the axis hole that is provided with and flexibly connects.
