Abstract
The invention discloses an air-pressure pipe bender. The air-pressure pipe bender comprises a workbench, an air cylinder, an air cylinder component, a pipe-bending pressure groove and rolling grooves. An air cylinder piston of the air cylinder is connected with the pipe-bending pressure groove through a telescopic shaft rod. A semi-circular groove opening with diameter matched with that of a pipe is formed in the pipe-bending pressure groove. The two rolling grooves which are used for positioning the two ends of the pipe and matching with the pipe-bending pressure groove to bend the pipe are formed in the workbench. Semi-circular groove openings with the diameter matched with that of the pipe are formed in the rolling grooves. Forward moving and backward moving of the air cylinder piston drive the telescopic shaft rod and the pipe-bending pressure groove to move forward or backward in the direction of the workbench. The air-pressure pipe bender has the advantages that short pipe bending is convenient, and manual short pipe bending is inconvenient to operate, so that the air-pressure pipe bender can improve the using rate of the short pipe in the construction site and lower material wastage.
Description
Technical field
The present invention relates to a kind of air pressure pipe bender.
Background technology
At present at architectural electricity construction field, based on hand, pipe bender bend pipe is pulled to the bend pipe of steel conduit, bend pipe of low quality, easily cause curved flat phenomenon, cause managing interior electric wire insulation layer and wear when drawing damaged.Manual bend pipe labour intensity is comparatively large, and efficiency of construction is low.And to the short tube that scene is blocked, cannot use again, cause steel conduit to waste.
Summary of the invention
The object of the invention is: provide a kind of air pressure pipe bender, its structure is simple, and bending quality is good, and operating efficiency is high.
Technical scheme of the present invention is: a kind of air pressure pipe bender, it comprises workbench, cylinder and cylinder assembly, bend pipe indent, slot rolling, the cylinder piston of described cylinder is by flexible axostylus axostyle bridge piece indent, bend pipe indent is provided with the semi-circular notch matched with pipe diameter, workbench is provided with and locates for tubing two ends and to coordinate bend pipe indent to carry out two slot rollings of bend pipe, slot rolling is provided with the semi-circular notch matched with pipe diameter; The flexible axostylus axostyle of the promotion that moves forward and backward of cylinder piston and bend pipe indent advance to workbench direction or return.
Described cylinder assembly comprises air inlet pipe, air valve, air hose, described air inlet pipe one end connects air pump, the other end connects air valve, air valve has two gas outlets, be connected respectively by the air inlet of air hose with cylinder two ends, the different airintake direction in cylinder two ends can realize moving forward and backward of cylinder piston respectively.
Described air valve is provided with the control crank in order to control cylinder airintake direction.
When described air hose is connected with cylinder air inlet, be socketed by sealing ring.
Described air pressure pipe bender includes a base, and described workbench and cylinder are arranged on base.
Described base bottom is provided with dragging pulley.
Advantage of the present invention is:
1, invention increases the efficiency that steel conduit is bending, duct bend manufacturing speed brings up to 4/minute, and reduces the labour intensity of labourer's bent steel conduit.And the present invention does not need professional to operate, and professional's operation that the required handicraft of manual bend pipe is good, can labour cost be saved.
2, the present invention guarantees that electrical construction steel conduit bending radius and curved compression reach code requirement, and steel conduit bending radius is greater than 6 times of conduit diameter.The curved compression in steel conduit knee is less than 0.1 times of conduit diameter.
3, curved spool is convenient in the present invention, and manual curved spool is inconvenient to operate.Therefore the present invention can improve the utilization rate of job site short tube, reduces spillage of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Fig. 1, a kind of air pressure pipe bender, it comprises air inlet pipe 1, control crank 2, air valve 3, air hose 4, cylinder 5, flexible axostylus axostyle 6, bend pipe indent 7, slot rolling 8, base 9, drags pull bar 10, drags pulley 11.Air inlet pipe 1 one end connects air pump, and the other end connects air valve 3, and air valve 3 has two gas outlets, adopts air hose 4 to be connected with the two ends of cylinder 5.When air hose 4 is connected with cylinder 5 air inlet, adopt sealing ring socket.Air valve 3 is provided with control crank 2, the airintake direction of control cylinder 5.Output pressure when air pump runs usually is 8Kg, and when control crank 2 is allocated to workbench direction, air pressure-loading is on cylinder 5 piston, and piston both sides produce draught head, and the flexible axostylus axostyle 6 of promotion and bend pipe indent 7 advance to workbench direction.When control crank 2 is allocated in the other direction, airintake direction changes front end airflow into, oppositely gives cylinder 5 piston pressurization, and the flexible axostylus axostyle 6 of promotion and bend pipe indent 7 return initial position.
