Further, the clamping cylinder that gas pushes away oily apparatus structure comprises air inlet pipeline, oil storage tank, the acting cylinder being connected with oil storage tank and the pressurized cylinder that acting cylinder is pressurizeed, air inlet pipeline separates a road entrance pressure pipeline and is connected with oil storage tank, air inlet pipeline separates another road pressure pipeline and is connected with pressurized cylinder, on entrance pressure pipeline, be connected with propelling magnetic valve, on pressure pipeline, be provided with and add pressure electromagnetic valve.
Further, the piston area of pressurized cylinder and acting cylinder is than being 10:1.
Further, on air inlet pipeline, be connected with pressure-stabilizing pressure regulation valve.
Further, entrance pressure pipeline is connected with one-way throttle valve between propelling magnetic valve and oil storage tank.
Further, pressure pipeline is connected with pressure-reducing valve adding between pressure electromagnetic valve and pressurized cylinder.
Further, pressurized cylinder outer setting is useful on the air gauge of detected pressures value.
The invention has the beneficial effects as follows: the present invention is by bend pipe mould, clamping bend pipe mould, guiding clamping and drive the cylinder of workpiece to carry out compact design, simple in structure, use floor space is little, and by the clamping cylinder of crucial power section is designed to gas, push away oily apparatus structure, greatly reduce bending machine energy consumption.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
Fig. 1 is the plane structure chart of a kind of Pneumatic type pipe bender for small pipe fittings of the present invention;
Fig. 2 clamps the structural representation of cylinder in a kind of Pneumatic type pipe bender for small pipe fittings of the present invention.
The specific embodiment
With reference to Fig. 1, on workbench, a kind of Pneumatic type pipe bender for small pipe fittings of the present invention comprises over against the bend pipe mould 2 arranging and the cylinder 1 of loosing core.During work, small-sized pipe fitting is enclosed within on core_pulling pole 8, then puts in the tube seat of bend pipe mould 2.At bend pipe mould 2, make the opposite side of flexure operation, perpendicular being relatively set with clamps bend pipe mould 6, and under the drive of clamping cylinder 5, clamping bend pipe mould 6 moves ahead to coordinate and clamps pipe fitting.Be provided with guiding clamping 4 with clamping bend pipe mould 6 homonymies.Clamp bend pipe mould 6 and clamping cylinder 5 and complete after time delay a period of time in action, guiding clamping 4 is pushed down forward pipe fitting under guide cylinder 3 drives, for pipe fitting bend tension leads.After guide cylinder 3 has moved and put in place, time delay a period of time, rotary cylinder 7 operates and drives bend pipe mould 2 to carry out the bend tension of pipe fitting.And at bend pipe mould 2, make the homonymy of flexure operation, and according to bending pipes radian, make needs, in predetermined position, be provided with locating piece 9.When rotating to locating piece 9 place, pipe fitting bend tension automatically stops.The cylinder 1 of loosing core starts backward movement, exits core_pulling pole 8, takes out pipe fitting.
With reference to Fig. 2, in the present invention, drive the clamping cylinder 5 that clamps bend pipe mould 6 to adopt gas to push away oily apparatus structure.Concrete structure is to comprise air inlet pipeline 13, oil storage tank 10, the acting cylinder 11 being connected with oil storage tank 10 and the pressurized cylinder 12 that acting cylinder 11 is pressurizeed, air inlet pipeline 13 separates a road entrance pressure pipeline 14 and is connected with oil storage tank 10, air inlet pipeline 13 separates another road pressure pipeline 15 and is connected with pressurized cylinder 12, on entrance pressure pipeline 14, be connected with and advance magnetic valve 16, on pressure pipeline 15, be provided with and add pressure electromagnetic valve 17.
During clamping cylinder 5 work, compressed air enters entrance pressure pipeline 14 and pressure pipeline 15 by air inlet pipeline 13.On air inlet pipeline, be provided with pressure-stabilizing pressure regulation valve 18, for compressed-air actuated air pressure is regulated.Be arranged on the startup of first switching on of propelling magnetic valve 16 on entrance pressure pipeline 14, compressed air enters oil storage tank 10 by entrance pressure pipeline 14.In order to regulate entering the compressed air of oil storage tank 10, on entrance pressure pipeline 14 sections that advance between magnetic valve 16 and oil storage tank 10, be connected with one-way throttle valve 19.Compressed air enters after oil storage tank 10, and the hydraulic oil in oil storage tank 10 enters fast acting cylinder 11 under compressed-air actuated promotion, and the piston rod of acting cylinder 11 is released and clamped bend pipe mould 6 clamping work pieces fast, realizes fast forward action.Then, add pressure electromagnetic valve 17 and start energising startup, thereby compressed air enters pressurized cylinder 12 by pressure pipeline 15, form superchargings.For reaching pressurization effect, the piston area of pressurized cylinder 12 is greater than acting cylinder 11 piston areas.Preferably, the piston area ratio of pressurized cylinder 12 and acting cylinder 11 is designed to 10:1.During pressurized cylinder 12 work, vat drives little cylinder, and acting cylinder 11 is formed to supercharging, makes the clamping bend pipe mould 6 being connected with the piston thick stick of acting cylinder 11 clamp pipe fitting, reaches pipe fitting and adds needed chucking power in man-hour.For controlled to chucking power, adapt to different pipe fittings to adding the needs of the power of holding, can regulate by 18 pairs of compressed air pressures that enter pressure pipeline 15 of the pressure-stabilizing pressure regulation valve on air inlet pipeline 13 on the one hand, can on pressure pipeline 15 sections that add between pressure electromagnetic valve 17 and pressurized cylinder 12, pressure-reducing valve 20 be set on the other hand, to entering the compressed air pressure of pressurized cylinder 12, regulate.Pressurized cylinder 12 outsides can be provided with the air gauge 21 for detection of force value, facilitate pressure to regulate.After pipe fitting machines, advance magnetic valve 16 and add pressure electromagnetic valve 17 power-off simultaneously, pressurized cylinder 12 and acting cylinder 11 reset to reset condition, wait for the arrival that advances magnetic valve 16 next time and add pressure electromagnetic valve 17 energising work.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
