This device is mainly by element body control module group up and down, guiding mechanism, and load maintainer and frame are formed, and element body control module group is made up of a plurality of element body control modules that can independently adjust up and down.
Independent guiding mechanism is by adjusting application of motor 12 (can adopt common minitype speed reducing motor), simple and easy rotation angle detecting apparatus 13, control circuit 14 (can adopt CPU to handle integrated circuit) is formed, realize FEEDBACK CONTROL by corresponding software, accurately control the stroke of element body, simple and easy rotation angle detecting apparatus 13 is contained on the motor rear end output shaft 15 of adjusting application of motor 12, simple and easy rotation angle detecting apparatus 13 is combined by grooved light lotus root 16 and trilobed wheel 17, control circuit is divided into a plurality of feature boards, constitute compact control module with three-dimensional combined method again, and be installed in and adjust on the application of motor 12, form integral structure.Simple and easy angle detection device 13 is in order to control displacement and speed, control the revolution of motor and rotating speed to be provided with.Its structure is consulted Fig. 3.
For realizing the power supply of control signal, detection signal and detecting position displacement sensor generally being arranged to the adjustment displacement of element body and the control of speed.The sensor that detects displacement will be connected with fixed part with moving component; For mold-free multi-point forming device, use hundreds and thousands of regularly arranged, adjustable for height element body (drift 11), each element body all has the power supply of control signal, detection signal and detecting position displacement sensor.For realizing non-mould multi-point forming, element body shown in Figure 2 unit is made up of element body, simple and easy angle detection device 13 and polylith integrated circuit, and structure is very compact.
Consult Fig. 5: utilize the eccentric structure of motor output shaft 20,, can arrange that between motor single reinforcement 19 consults Fig. 4, also can arrange two reinforcements 21 in order to improve the stress of the fixing big plate 18 of element body
Independent guiding mechanism adopts the master slave control mode, adjust in the time of by a plurality of element body of computer realization, said master slave control mode is to arrange a plurality of repeaters under the computer, and with each repeater control multiple electric motors, repeater adopts dual-cpu structure again.
All element body control modules constitute the master-slave mode computer-controlled network with master computer, and its structure is consulted shown in Figure 6: the The whole control net adopts RS485 or other industry spot network.Because the criteria limit of network, a computer interface can only link to each other with the control module of some, for example in the RS4SS standard, can only connect 32 control modules at most.In order to control a large amount of element bodies simultaneously, adopt repeater that network is expanded, when needs expansion communication distance, all repeaters should be connected in series, do not have in the mould multi-point quick forming device at sheet material, because of expanding the communication number of connections, all repeaters adopt parallel connection to connect shown in frame of broken lines among Fig. 6.In control network shown in Figure 6, computer and each control module logically have equity, and promptly the information that computer and each control module sent is with all unit on the traverses network.In order to realize the communication between master computer and each the control list, every frame data should comprise following information at least: (1) is initial and synchronous, (2) order or response, and (3) communication unit is encoded, (4) data, finish and verification (5).
Consult Fig. 6: in order to realize the automatic switchover of direction of communication, repeater adopts two CPU symmetrical structures, and communication process be " serial---walk abreast---serial " mode, and is symmetrical in two ends of repeater.Be to improve the repeater interference free performance, two mutual house dogs of CPU (WatChDog) of repeater, when a CPU crashes because of accidental cause, another CPU meeting " perceive " to and send the CPU that reset command makes deadlock and reset and normally move.
The major function of control module is order and the data that receive host computer, and finishes the control corresponding function by order.Its structure is consulted shown in the figure 7.The The whole control unit, is received order and returns running status to host computer by the RS485 communication interface as the control core by a slice single-chip microcomputer (CPU).CPU is according to the difference of the control command of receiving, send control command by photoelectric isolating circuit to program control torque motor driver, make motor moment of torsion and rotational speed on demand, and return corner information to CPU by rotation angle detecting apparatus, realize closed-loop control, and then reach the purpose of accurate adjustment element body.Rotation angle detecting apparatus is made of grooved optocoupler, impeller and interlock circuit.When only doing the corner detection, the angle that turns over can only be detected, direction of rotation can not be discerned with a grooved optocoupler and impeller.In the element body control module, owing to motor steering is controlled by CPU, so only discern adjustment direction and the height that the angle that turns over just can calculate element body.
By program control torque motor driver, CPU can control motor when curved surface transfers shape to adjust with initial bit with different peak torques and speed, reach best control effect.Watchdog circuit can automatically reset when CPU crashes and reset computer.On software, adopt special treatment method, make operating point and then breakpoint succession operation before CPU resets back " remembeing " deadlock.
For independent control element body control module has nearly ten lines such as power line, displacement detecting holding wire and feedback line routinely, total nearly 400 element bodies (thousands of element bodies sometimes), Duo line can't connect like this, and fault rate is also high.Therefore, the independent guiding mechanism that present technique adopts adopts the multilayer arrangement, and all centralized arrangement makes overall structure compact more at the rear portion of element body.
Because after the various errors operations repeatedly such as the mechanical clearance of element body, detection error, the error of calculation, the element body moulding produces error, in order to eliminate error, need be after the operation repeatedly to element body group leveling (zeroing).The utility model uses the control mode of restriction Motor torque, to element body group's leveling or zeroing.For the sake of simplicity, utilize a surface plate to be placed on the workbench, vertical with the element body group (perpendicularity is decided on request) as far as possible, this is to adjust element body to contact with surface plate, when Motor torque (electric current of the motor of flowing through) when being increased to certain value, feed back a signal and give computer, make the motor stall and certain revolution that reverses, other element body also so moves one time.
For the shape that adapts to different plate material parts and the needs of forming mode, element body control module group number can change up and down, and flanging cylinder number also can change.
