The invention has the beneficial effects as follows: the present invention carries out Compact Design with the cylinder of bend pipe mould, clamping bend pipe mould, guiding clamping and drive workpiece; Simple in structure; The use floor space is little; And be designed to gas through clamping cylinder and push away oily apparatus structure, greatly reduce the bending machine energy consumption crucial power section.
Description of drawings
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is the plane structure chart of a kind of small-sized pipe fitting pneumatic type bending machine of the present invention;
Fig. 2 is the structural representation of cramping cylinder in a kind of small-sized pipe fitting pneumatic type bending machine of the present invention.
The specific embodiment
With reference to Fig. 1, on workbench, a kind of small-sized pipe fitting pneumatic type bending machine of the present invention comprises over against the bend pipe mould that is provided with 2 and the cylinder 1 of loosing core.During work, small-sized pipe fitting is enclosed within on the core_pulling pole 8, puts into then in the tube seat of bend pipe mould 2.Make the opposite side of flexure operation at bend pipe mould 2, perpendicular being relatively set with clamps bend pipe mould 6, under the drive that clamps cylinder 5, clamps bend pipe mould 6 and moves ahead to cooperate and clamp pipe fitting.Be provided with guiding clamping 4 with clamping bend pipe mould 6 homonymies.Clamp bend pipe mould 6 and clamp cylinder 5 after time-delay a period of time is accomplished in action, guiding clamping 4 is pushed down pipe fitting forward under guiding cylinder 3 drives, for the pipe fitting bend tension leads.After 3 actions of guiding cylinder were accomplished and put in place, time-delay a period of time, rotary cylinder 8 operated and drives the bend tension that bend pipe mould 2 carries out pipe fitting.And make the homonymy of flexure operation at bend pipe mould 2, according to bending pipes radian making needs, be provided with locating piece 9 in predetermined position., the pipe fitting bend tension stops automatically when rotating to locating piece 9 places.The cylinder 1 of loosing core begins backward movement, withdraws from 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 and 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 that links to each other with oil storage tank 10 and the pressurized cylinder 12 that acting cylinder 11 is pressurizeed; Air inlet pipeline 13 is told one road entrance pressure pipeline 14 and is linked to each other with oil storage tank 10; Air inlet pipeline 13 is told another road pressure pipeline 15 and is linked to each other with pressurized cylinder 12; Be connected with on the entrance pressure pipeline 14 and advance magnetic valve 16, pressure pipeline 15 is provided with and adds pressure electromagnetic valve 17.
When clamping cylinder 5 work, compressed air gets into entrance pressure pipeline 14 and pressure pipeline 15 through air inlet pipeline 13.Air inlet pipeline is provided with voltage regulation of voltage regulation valve 18, is used for compressed-air actuated air pressure is regulated.Propelling magnetic valve 16 energising earlier that is arranged on the entrance pressure pipeline 14 starts, and compressed air gets into oil storage tank 10 through entrance pressure pipeline 14.For the compressed air that gets into oil storage tank 10 is regulated, on entrance pressure pipeline 14 sections that advance between magnetic valve 16 and the oil storage tank 10, be connected with one-way throttle valve 19.After compressed air got into oil storage tank 10, the hydraulic oil in the oil storage tank 10 got into acting cylinder 11 fast under compressed-air actuated promotion, and the piston rod of acting cylinder 11 is then released fast and clamped bend pipe mould 6 clamping work pieces, realizes the F.F. action.Then, add pressure electromagnetic valve 17 and begin the energising startup, form superchargings thereby compressed air gets into pressurized cylinders 12 through pressure pipeline 15.For reaching the 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 supercharging, makes the clamping bend pipe mould 6 that links to each other 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 through 18 pairs of compressed air pressures that get into pressure pipeline 15 of the voltage regulation of voltage regulation valve on the air inlet pipeline 13 on the one hand; Can on pressure pipeline 15 sections that add between pressure electromagnetic valve 17 and the pressurized cylinder 12, pressure-reducing valve 20 be set on the other hand, the compressed air pressure that gets into pressurized cylinder 12 is regulated.Pressurized cylinder (12) outside can be provided with the air gauge (21) that is used for the detected pressures value, makes things convenient for pressure to regulate.After pipe fitting machines, advance magnetic valve 16 and add pressure electromagnetic valve 17 and cut off the power supply simultaneously, pressurized cylinder 12 resets to reset condition with acting cylinder 11, waits for advancing magnetic valve 16 and the arrival that adds pressure electromagnetic valve 17 energising work next time.
More than be that preferable enforcement of the present invention is specified; But the invention is not limited to said embodiment; Those of ordinary skill in the art make all equivalent variations or replacement under the prerequisite of spirit of the present invention, also can doing, and distortion that these are equal to or replacement all are included in the application's claim institute restricted portion.
