The specific embodiment
CNC tube bending machine of the present invention, as shown in Figures 1 to 4, includes lathe 100, pay-off 200, left contra-angle handpiece 300, right contra-angle handpiece 400, servomotor and numerical control device 500.
Left contra-angle handpiece 300 is arranged on a side of lathe 100 leading sections, comprising: fixed axis 301, circle mould 302, pattern 303, pattern travelling mechanism, clamping 304, clamping travelling mechanism and bending arm; Fixed axis 301 is fixedly installed on left contra-angle handpiece 300, and bending arm is rotatable to be arranged on head, and for bending pipe fitting, preferably, bending arm is around fixed axis 301 rotary setting.
Preferably, circle mould 302 is arranged on fixed axis 301, and circle mould 302 is determined pipe fitting and the crooked radius that bends different-diameter according to the shape of self; Pattern 303 misplaces and is arranged on left contra-angle handpiece 300 with circle mould 302 left and right, pattern 303 is connected with pattern travelling mechanism, by numerical control device 500, control pattern travelling mechanisms and adjust it and justify the distance between mould 302, coordinate with the round mould 302 being fixedly installed, play the effect that clamps and unclamp pipe fitting; Preferably, on bending arm, be also provided with clamping 304, clamping 304 is connected with clamping travelling mechanism, by numerical control device 500, controlling clamping travelling mechanisms adjusts it and justifies the distance between mould 302, play the effect that clamps and unclamp pipe fitting, meanwhile, clamping 304 can rotatablely move with bending arm, for bending of pipe fitting provides bending power;
In the upper plane of lathe 100, be provided with the first slide rail 101 extending longitudinally, the second slide rail 102 of horizontally set and the lead-screw drive mechanism 103 of horizontally set.
Pay-off 200 is arranged on the first slide rail 101, by servomotor, is driven and can be moved forward and backward along the first slide rail 101.Pay-off 200 is also connected with lead-screw drive mechanism 103, can be driven along the second slide rail 102 transverse shiftings by lead screw transmission structure.Pay-off 200 also comprises feed spool 201, and feed spool can be around its central axis rotation, and feed spool leading section is provided with clamp mechanism 202, and clamp mechanism is preferably triangle clamp manipulator, and pay-off 200 is for being transported to pipe fitting suitable bending position.
The architectural feature of right contra-angle handpiece 400 and left contra-angle handpiece 300 symmetries, itself and left contra-angle handpiece 300 are arranged on the opposite side of lathe 100 leading sections symmetrically.
When needs bend pipe fitting, first straight tube needs being bent is contained in clamp mechanism, clamp mechanism clamps pipe fitting, start the machine, pay-off 200 moves along the first slide rail 101, the first bending point of pipe fitting is delivered to round mould 302 places, pattern travelling mechanism drives pattern 303 close to circle mould 302, coordinate with circle mould 302, to pipe fitting the right and left, carrying out spacing, play the effect of helping tensioning pipe fitting, then by clamping travelling mechanism, drive clamping 304 close to circle mould 302, coordinate and clamp pipe fitting with circle mould 302, the radian that left contra-angle handpiece 300 is set around fixed axis 301 rotations by driven by motor, the bending that is pipe fitting by clamping 304 provides bending power, bend pipe fitting, after the first bending place completes, unclamp clamping 304 and pattern 303, pay-off 200 continues by seesawing, and the second bending point of pipe fitting is delivered to round mould 302 places, continues above-mentioned steps, completes the second bending part bending, the like, complete the bending operation of pipe fitting.
In above step, in order to meet the needs that bend pipe fitting, can also by the rotation of feed spool 201, make pipe fitting rotate a certain angle.
When left contra-angle handpiece 300 cannot complete bending of pipe fitting, numerical control device 500 is controlled lead-screw drive mechanism 103 and is driven pay-off 200 along the second slide rail 102, to move laterally to the another side of lathe 100, coordinates right contra-angle handpiece 400 to complete bending of pipe fitting.
According to bending machine of the present invention, especially applicable air-conditioner exhaust pipe assembly bends.Following table is for being used CNC tube bending machine of the present invention to bend the movement decomposition of blast pipe, in the present embodiment, all to stand in the visual angle that CNC tube bending machine head section partly sees to tail, the rotation direction of each parts described:
Wherein, completed after step 8, need to carry out to pipe fitting next step 90 degree bendings, now, the 4th below of curved position in left contra-angle handpiece 300 due to blast pipe, if continue to carry out next step 90 degree bending operations at left contra-angle handpiece 300, the 4th curved position of blast pipe can interfere with the fuselage sections of lathe 100, cannot bending.For avoiding above problem, blast pipe need to be changed to a direction bends, therefore by lead-screw drive mechanism 103, drive pay-off 200 along the second slide rail 102, to move laterally to a side of right contra-angle handpiece 400, pipe fitting is placed on right contra-angle handpiece 400, by right contra-angle handpiece 400, complete and bend.
Be illustrated in figure 5 the pipe fitting of welding fabrication, be illustrated in figure 6 the pipe fitting that adopts CNC tube bending machine of the present invention to bend moulding, two pipe fittings size, angle are all consistent, all meet the related request of air-conditioning system through dependence test.Compare with the tube manufacture mode of welding fabrication, use CNC tube bending machine of the present invention to save 1 blanking, 1 moulding, 1 bend pipe and 1 welding sequence, when having improved operating efficiency, improved the stability of pipe fitting, guaranteed the crudy of pipe fitting.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
