Below be the further explanation to technique scheme:
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 by the air inlet of air hose with the cylinder two ends respectively, the different airintake direction in cylinder two ends can be realized moving forward and backward of cylinder piston respectively.
Described air valve is provided with the control crank in order to the control cylinder airintake direction.
When described air hose is connected with cylinder air inlet, by the sealing ring socket.
Described air pressure bending machine includes a base, and described workbench and cylinder are arranged on the base.
Described base bottom is provided with and drags pulley.
Described cylinder both sides are provided with the shockproof support of triangular form.
Described workbench top is provided with the pull bar that drags for convertible angle.
The place ahead exercise end of described bend pipe indent and the relative position of slot rolling are determined angle and the bending radius of bend pipe.
The semi-circular notch of described bend pipe indent and slot rolling and the matching precision of pipe diameter are foundation with the curved compression of guaranteeing the knee less than 0.1 times of pipe diameter.
Advantage of the present invention is:
1, the present invention has improved the efficient of steel conduit bending, and the duct bend manufacturing speed is brought up to 4/minute, and has reduced the labour intensity of labourer's bent steel conduit.And the present invention does not need the professional to operate, and the good professional's operation of the essential handicraft of manual bend pipe can be saved labour cost.
2, the present invention guarantees that electrical construction steel conduit bending radius and curved compression reach code requirement, and the 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.
4, elbow lateral deviation of the present invention is little, and conduit is connected the back levelness with elbow and perpendicularity meets code requirement.
5, air pressure bending machine bend pipe of the present invention does not go out substandard products, and bending quality is good, elbow is consistent attractive in appearance; And pipe can appear suppressing in manual bend pipe, and is of poor quality, that effect is installed is not attractive in appearance.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present invention.
Wherein: 1 air inlet pipe; 2 control cranks; 3 air valves; 4 air hoses; 5 cylinders; 6 flexible axostylus axostyles; 7 bend pipe indents; 8 slot rollings; 9 bases; 10 drag pull bar; 11 drag pulley.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of air pressure bending machine, 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 ends connect air pump, and the other end connects air valve 3, and air valve 3 has two gas outlets, adopt air hose 4 to be connected with the two ends of cylinder 5.When air hose 4 is connected with cylinder 5 air inlets, adopt the sealing ring socket.
Place cylinder 5 and workbench on the base 9, cylinder 5 both sides arrange the shockproof support of triangular form.Bend pipe indent 7 and slot rolling 8 are positioned on the workbench, and flexible axostylus axostyle 6 adopts a silk mouthful screw thread to be connected with bend pipe indent 7.Workbench is provided with two slot rollings 8, is used for the location, two ends of steel conduit.The place ahead exercise end of bend pipe indent 7 and the relative position of slot rolling 8 are determined angle and the radius of bend pipe to make bending radius greater than 6 times of the electric conduit diameter.
