The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The specific embodiment of the utility model such as Fig. 1-shown in Figure 6; Material carrying mechanism before a kind of trailing type of plate bending machine comprises housing 1, is located at drive unit, transmission mechanism and follow-up material-supporting plate 2 on the housing 1, and transmission mechanism links to each other with drive unit; This transmission mechanism comprises a wildhaber-novikov gear 3 as main actuator; Wildhaber-novikov gear 3 is fixed on the follow-up material-supporting plate 2, and the plane, reference circle place of wildhaber-novikov gear 3 is vertical with follow-up material-supporting plate 2.Because workpiece all is to make bending motion around a centre point in whole bending process, therefore, adopt the main actuator of wildhaber-novikov gear 3, and the pivot in the workpiece bending process on the center of circle of wildhaber-novikov gear 3 and the follow-up material-supporting plate 2 overlaps as follow-up material-supporting plate 2.
In the present embodiment; Also be provided with guiding mechanism on the housing 1; This guiding mechanism comprises and being used for wildhaber-novikov gear 3 along two pairs of V-arrangement guide rollers 4 that its movement locus leads that be specially: each lays respectively at the inside and outside both sides of wildhaber-novikov gear 3 to two V-arrangement guide rollers in the V-arrangement guide roller 4.If the pivot in the workpiece bending process on the follow-up material-supporting plate 2 is the bending centre point, each to the installation circle center line connecting of V-arrangement guide roller 4 all through the bending centre point.Housing 1 comprises stationary housing of being located on the workbench 16 11 and the movable housing 12 that is used to install follow-up material-supporting plate 2; Follow-up material-supporting plate 2 is fixed in the top of movable housing 12; With the top end sealing of movable housing 12, wildhaber-novikov gear 3 is located in the movable housing 12, and follow-up material-supporting plate 2 bottoms are fixed in these wildhaber-novikov gear 3 upper ends; And the two side faces that parallels with wildhaber-novikov gear 3 reference circles on the movable housing 12 is fan-shaped; Drive unit and guiding mechanism all are installed in the stationary housing 11.
In the present embodiment; Drive unit is a servomotor 5; Transmission mechanism also comprises decelerator 6, belt wheel synchronous drive mechanism and driving gear 7, and the input of belt wheel synchronous drive mechanism and output are respectively equipped with the first arc toothed belt wheel 9 and second arc toothed belt wheel 10, the first arc toothed belt wheels 9 link to each other with decelerator 6 and driving gear 7 respectively with the second arc toothed belt wheel 10; Driving gear 7 is suitable with wildhaber-novikov gear 3, promptly is meshed; Servomotor 5, decelerator 6, belt wheel synchronous drive mechanism and driving gear 7 all are located in the stationary housing 11.
Because carrying out the action of journey, the worker of bender slide block 13 whether stablizes; Be to feed back to the laggard line number a tree name of digital control system through the pulse signal that is installed in the pulse signal generator 8 on the bender slide block 13 to analyze and revise and realize; And the work speed of the speed of service of wildhaber-novikov gear 3 must be with slide block 13 descending bendings the time conforms to fully; Follow-up material-supporting truly could be realized, otherwise effect will be do not had with bending workpieces action retainer.Therefore; In the present embodiment; Pulse signal when being used to control the descending bending of the pulse signal generator 8 transmission slide blocks 13 of bender top shoe 13 work speeds is given servomotor 5; Be that the pin as the pulsed signal end links to each other on pulse signal transmitting terminal and the motor servo driver of pulse signal generator 8; Pulse signal during with bender slide block 13 work speeds is controlled servomotor 5 operation, and then drives wildhaber-novikov gear 3 and rise, so that the work speed of the rate of climb of wildhaber-novikov gear 3 during with slide block 13 descending bendings conforms to fully.In the present embodiment; Pulse signal generator 8 adopts the grating chi; The model of motor servo driver is MCDDT3520, referring to Fig. 6, on the pulse signal transmitting terminal of grating chi and the motor servo driver as the pulsed signal end the 3rd, 4,5,6 pins link to each other.
Operation principle is following: when retainer is effective before the retainer selector switch is in servo-actuated before the servo-actuated, digital control system be in semi-automatic or automatic mode under, when stepping on the downward floor push of bender slide block 13; And during bender slide block 13 descending arrival clamping point (worker advances) positions, the pulse signal of grating chi gets into servomotor 5, and servomotor 5 is started working; Be that servomotor 5 is just changeing, the brake of the servomotor of retainer is unclamped before the servo-actuated, servomotor 5 beginning connection signals; Material carrying mechanism is started working before the servo-actuated, and the pulsed quantity that the setting of root a tree name needs drives servomotor 5 and rotates, at this moment; Along with bender slide block 13 descending (worker advances) workpiece bending; Follow-up material-supporting plate 2 is upset synchronously upwards also, and when arriving the angle position that digital control system edits, follow-up material-supporting plate 2 stops upwards upset.The bending angle of workpiece can root a tree name client actual needs change at any time, in the present embodiment, the flip angle of follow-up material-supporting plate 2 is adjustable 0 °-60 °.Can change the reversal rate of follow-up material-supporting through the gear speed ratio of change servomotor 5 intrinsic parameters setting, make the upward stroke of wildhaber-novikov gear 3 controllable.
When bender advances to finish, bender slide block 13 quick returns, and can not rely on slide block grating chi pulse to drive servomotor 5 during follow-up material-supporting plate 2 returns towards signal; Because be about 0.5 second the return interval of bender slide block 13; If follow-up material-supporting mechanism is backhaul in 0.5 second also, must cause great impact and danger, therefore; In the present embodiment, material carrying mechanism also comprises and is used to control the at the uniform velocity switch loop of backhaul of follow-up material-supporting plate 2 before the trailing type.
Referring to Fig. 6; Above-mentioned switch loop mainly comprises auxiliary reclay KA6 and internal speed K switch A0; The 32nd pin that is used for the implementation pattern conversion on auxiliary reclay KA6 and the motor servo driver links to each other, and the position control mode when promptly being used for the servomotor original state converts the internal speed control model into.Internal speed K switch A0 is used to change the internal speed of servomotor 5, and auxiliary reclay KA6 and internal speed K switch A0 constitute the loop, and internal speed K switch A0 links to each other with the 33rd pin on the motor servo driver.
Its operation principle is following: after follow-up material-supporting plate 2 stops to rise, this moment bender slide block 13 quick returns, digital control system can be sent a bending END instruction; Auxiliary reclay KA6 adhesive work; The servomotor 5 of material carrying mechanism transfers the internal speed control model to by position control mode before the control trailing type, and through timing closing internal speed K switch A0, servomotor 5 is started working by the speed of inner setting; Be servomotor 5 counter-rotatings; 2 speed according to servomotor 5 inner settings of follow-up material-supporting plate are overturn at the uniform velocity downwards, and when arriving the angle position that digital control system edits, servomotor 5 quits work; Follow-up material-supporting plate 2 resets, and gets into operation cycle for the second time.
The above embodiments are merely the preferred embodiment of the utility model, can not limit the interest field of the utility model with this, and therefore, the equivalent variations according to the utility model claim is done still belongs to the scope that the utility model is contained.
