Abstract
The utility model provides a pipe bender with simple structure for operation conveniently which is particular suitable for bending PVC pipe water-proof bend. The pipe bender includes a base, a fixed wheel set on the base; an operation handle, one end is rotary connected with the fixed wheel shaft core for rotating in the plane parallel with the fixed wheel around the fixed wheel shaft core; a travelling block connected with the operation handle and in a same plane with the fixed wheel; an antiroll column set on the base and extruded to the fixed wheel located plane. A pipe need to be bend passes through between the fixed wheel and the travelling block which needs not the bent part contacting with the antiroll column for preventing the pipe rotation, then the operation handle is run, the travelling block orbital revolves around the fixed wheel shaft core, the travelling block forces the pipe bending to the bender pipe along the fixed wheel outer peripheral face.
Description
Technical field
The utility model relates to a kind of pipe bender, particularly a kind of pvc pipe pipe bender.
Background technology
Along with the construction in new rural area, rural economy is in fast development, and the life of farmers level is greatly improved, and the power consumption in rural area is rapidly increasing progressively, and the rural power grids construction is in continuous quickening.The curved making of pvc pipe waterproof does not have special-purpose bend pipe tools in the service conductor transformation, generally leans on the manual winding pipe of PVC waterproof made from spring, and there are a lot of defectives in this method, as: 1, bend pipe making qualification rate is low; 2, big or small disunity; 3, time-consuming, effort etc.In order to address these problems, so designed the curved pipe bender of pvc pipe waterproof.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate pipe bender, is particularly useful for curved the bending of pvc pipe waterproof.
This pipe bender comprises pedestal;
Fixed wheel is arranged on the pedestal;
Operating grip, an end is rotatably connected on the axle center of fixed wheel, can rotate in the fixed wheel axle center is being parallel to the plane of fixed wheel;
Movable pulley is connected on the operating grip, and with fixed wheel in same plane;
Pole pendulum prevented is arranged on the pedestal, reaches in the plane, fixed wheel place.
During use, the pipe (as the pvc pipe) that needs are bent passes between fixed wheel and movable pulley, and the part that need bend does not contact with pole pendulum prevented to prevent that pipe from rotating.Rotating operation handle then, movable pulley promptly revolves round the sun around the axle center of fixed wheel, and movable pulley is bent into bend pipe with regard to forcing pipe along the outer peripheral face of fixed wheel.
The utility model is simple in structure, easy to operate, is particularly useful for curved the bending of pvc pipe waterproof.
In order to adapt to the pipe of different-diameter, movable pulley is along on the diverse location that axially is detachably connected on operating grip of operating grip; Pole pendulum prevented is detachably connected on the diverse location of pedestal along the fixed wheel radial direction.
In order to make the radian that pipe is bent part control, it also comprises and is arranged on the pedestal and reaches radian control lever in the plane, fixed wheel place.When bending, can contact with the radian control lever in the process of bending by pipe one end that bent, the radian control lever has prevented that the pipe continuation is along the bending of fixed wheel outer peripheral face, to accomplish being controlled by the radian of pipe bending.Certainly, can be changed by the radian of pipe bending in order to make, the radian control lever is detachably connected on the diverse location of pedestal along the fixed wheel circumferential direction.
For the length that bends part is controlled (bending the oversize waste that causes pvc pipe of part extension elongation to avoid pvc pipe), it also comprises along following perpendicular bisector and is detachably connected on the pedestal and reaches pipe range control post in the plane, fixed wheel place, and described perpendicular bisector is pole pendulum prevented and the pole pendulum prevented perpendicular bisector to the line of fixed wheel outer surface closest approach.The pipe that needs are bent (as the pvc pipe) is when passing between fixed wheel and movable pulley, and an end that is bent contacts with pipe range control post, can control and bend length partly.

The specific embodiment
Pipe bender as Figure 1-3, pedestal 2 is fixed on the support 3, and fixed wheel 1 is arranged on the pedestal 2.Have arc groove 9 along the fixed wheel circumferential direction on pedestal, the radian control lever 10 that reaches in the plane, fixed wheel place removably is connected in the groove 9 by nut 21.Stretch out rotating shaft 4 from the axle center of fixed wheel.One end of operating grip 5 is rotationally connected in the rotating shaft 4, and it can rotate in the fixed wheel axle center is being parallel to the plane of fixed wheel.Axial direction along operating grip has groove 7.An end that is provided with the movable pulley axle 8 of movable pulley 6 removably is connected in the groove 7 by nut 20.Movable pulley and fixed wheel are in same plane.
Have groove 11 along the fixed wheel radial direction on pedestal, the pole pendulum prevented 12 that reaches in the plane, fixed wheel place removably is connected in the groove 11 by nut.
Pipe range control post 13 lower ends that reach in the plane, fixed wheel place are connected on the movable plate 14, have groove 15 on the movable plate 14, groove 15 is detachably connected on the support by nut, movable plate 14 can move along following perpendicular bisector, and described perpendicular bisector is pole pendulum prevented 12 and the perpendicular bisector of pole pendulum prevented to the line of fixed wheel 1 outer surface closest approach.
Operating procedure:
1) the pvc pipe caliber that bends is as required regulated the position of pole pendulum prevented 12 and movable pulley 6, and pvc pipe is placed between movable pulley 6 and the fixed wheel, makes pvc pipe contact with movable pulley 6, fixed wheel 1, pole pendulum prevented 12 simultaneously.
The length of the pvc pipe that 2) bends is as required regulated the position of movable plate 14, and an end that makes the needs of pvc pipe bend is controlled post 13 with pipe range and contacted.
3) be adjusted in the groove 9 radian control lever 10 to the appropriate location.
4) rotating operating handle contacts with radian control lever 10 up to pvc pipe.When operating grip rotated, movable pulley promptly revolved round the sun around the axle center of fixed wheel, simultaneously, the rotation of movable pulley moving pulley spindle, movable pulley forces pvc pipe to bend shaping along the outer peripheral face of fixed wheel.
