Description
Technical field
The present invention relates to a kind of bending apparatus of metal tube.
Background technology
The bending apparatus of existing metal tube comprises driving mechanism, bending die and metal tube supporting plate, and metal tube is placed on the metal tube supporting plate and is clamped by bending die, and the drive mechanism bending die rotates and the bending metals pipe fitting.Because the metal tube supporting plate is fixed, metal tube can move on the metal tube supporting plate in BENDING PROCESS and produce friction between the two, and metal tube can wear and tear even the wear down tube wall because of friction, influences the product quality after the bending; Also increase simultaneously the energy consumption of device because of friction.
Summary of the invention
The present invention will solve the above-mentioned deficiency of prior art and bending apparatus that a kind of metal tube is provided, makes its crooked pipe fitting quality good.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
The bending apparatus of metal tube; It is characterized in that: it comprises driving mechanism, bending die, servo-actuated supporting plate, pinion and rack and base plate; Said crooked mold shaft is connected on the support that is installed on the base plate and supports; Between bending die shaft end and the servo-actuated supporting plate pinion and rack is set and connects, be connected through slide mechanism between said servo-actuated supporting plate and base plate, drive mechanism bending die rotation or move the servo-actuated supporting plate and the rotoflector mould; Metal tube support bar one end is fixed by being fixed on the support on the base plate, and other end frame is on the servo-actuated supporting plate.
The gear of said gear rackwork is installed in the bending die axle head, and tooth bar is installed on the servo-actuated supporting plate.
The said gear rackwork has two, is separately positioned on two ends of crooked mold shaft.
Above-mentioned slide mechanism is slide and slide rail, and slide and slide rail are separately positioned on servo-actuated supporting plate and the base plate, and the servo-actuated supporting plate is mobile more convenient, steady like this.
When metal tube is crooked; Metal tube is set on the mandrel, and the one of which end is clamped by bending die, and the drive mechanism bending die rotates and drives the metal tube bending; Drive the servo-actuated supporting plate through rack and pinion drive mechanism simultaneously and press the track follow-up that the gear compound graduation circle limits; Said servo-actuated supporting plate moves on the slide rail that is fixedly arranged on the base plate through slide, and accomplishes the bending of whole metal tube, and metal tube does not relatively move in whole BENDING PROCESS and between the servo-actuated supporting plate.
Compared with prior art; The invention has the advantages that: during owing to the metal tube bending; The servo-actuated supporting plate of support metal pipe fitting can be followed the metal tube bending and servo-actuated, has therefore avoided relatively moving of servo-actuated supporting plate and metal tube, reduces the friction between servo-actuated supporting plate and metal tube thus; Thereby reduce the wearing and tearing of metal tube lateral wall, improve the quality of crooked back metal tube effectively.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, a kind of bending apparatus of metal tube comprises bending die 1, servo-actuated supporting plate 2, gear 3, tooth bar 4 and base plate 5.
1 of above-mentioned bending die is connected on left and right support 6 and 7 and by left and right support 6 and 7 and supports, and left and right support 6 and 7 is installed on the base plate 5, and bending die 1 can rotate according to its axle like this.
Two ends that above-mentioned bending die is 1 are installed gear 3, and gear is installed the tooth bar 4 that is mated 3 times, and tooth bar 4 is installed on the servo-actuated supporting plate 2, just links through gear 3, tooth bar 4 between bending die 1 and the servo-actuated supporting plate 2 like this.
Above-mentioned mandrel 12 1 ends are fixing by the fixed mount 16 that is fixed on the base plate, and the other end is attached on the backing plate 10, and backing plate 10 is fixed on by on the servo-actuated supporting plate 2.
Preferably be provided with and metal tube 9 corresponding to circular arcs on the above-mentioned backing plate 10, be convenient to place better metal tube 9.
Metal tube 9 is set on the mandrel 12; One end is clamped by bending die 1 and clamping 11; Bending die is connected clamping with clamping through screw, and the other end is spacing by the prominence 121 of mandrel 12, in the present embodiment bending die is divided into bending die 1 and clamping 11 2 parts; The both convenient metal tube 9 that clamps, convenient again the installation.
Driving mechanism in the present embodiment is a motor 14, and motor 14 is connected with connector 15 through axle, and connector 15 is connected with clamping 11 again, and motor 14 can pass through connector 15 and rotoflector mould 1 like this.
Above-mentioned connector 15 can be as a whole with clamping 11.
Also can move through drive mechanism servo-actuated supporting plate 2, servo-actuated supporting plate 2 drives bending die 1 rotation through rack and pinion mechanism again, thereby makes the metal tube that is fixed on the bending die 19 crooked and accomplish the bending work of metal tube 9.
During bending metals pipe fitting 9; Driving mechanism such as motor 14 drive bending die 1 and rotate, and bending die 1 drives metal tube 9 bendings, drive 2 follow-ups of servo-actuated supporting plate through rack and pinion drive mechanism simultaneously; Servo-actuated supporting plate 2 moves on the slide rail 13 that is fixedly arranged on the base plate 5 through slide 8; The friction of having avoided servo-actuated supporting plate 2 and metal tube 9 to relatively move like this, thereby the wearing and tearing of minimizing metal tube 9 lateral walls, the quality of the metal tube after the assurance bending.
Said gear 3 and the tooth bar 4 that cooperates thereof according to actual needs can conversion, and the serpentine track of metal tube changes with the variation of gear compound graduation circular diameter.
