1. method that is used to control optical glass non-spherical surface element hot press shaping machine, this method comprises a covering device, comprising:

  • Operating terminal (1) is used for feeding device through manual ringing parameter value or executable operations is set;

    Display terminal (2) is used for duty and shows and alarm indication;

    Alignment sensor (3) is installed on the drive apparatus, is used for the position of induction heat pressing machine operation;

    Scrambler (4) is used for the ruuning situation of feedback servo motor;

    Servoamplifier (5);

    Be used to receive the position signalling of the heat pressing forming machines operation that alignment sensor (3) responded to and servomotor run signal that scrambler (4) transmits and be transferred to controller (6);

    Simultaneously;

    Servoamplifier (5) carries out computing and produces Control current with other control signal according to the high-speed pulse that controller (6) transmits, through the action of scrambler (4) control servomotor;

    Controller (6);

    Be used to receive the operational order that operating terminal (1) transmits or the parameter of setting;

    And the position signalling of servomotor run signal that transmits from servoamplifier (5) and heat pressing forming machines operation;

    Carry out the integrated logic computing, produce high speed command pulse and the control signal of being correlated with and be transferred to servoamplifier (5), the while is in the duty of display terminal (2) display system;

    It is characterized in that the method comprising the steps of;

    Step 1, after said device electrifying startup and the self check success, controller (6) is judged that according to the RD signal of servoamplifier (5) and ALM signal condition system is whether ready and can be run well, in this way, changes step 2 over to;

    Step 2 is set the heat pressing forming machines running parameter through operating terminal (1), comprising;

    RP setting value 50-100mm;

    Position of conversion point 100-180mm at a slow speed soon;

    Maximum position of conversion point 130-200mm, low speed returns buffer distance 0-30mm, fast speed 180-333mm/s;

    Jogging speed 10-50mm/s, the die mould time 0-100s of 1-4 section and the setting value of pressure 0-3.3T;

    Step 3 is carried out original point return and the operation that resets through the button on the operating terminal (1), and at this moment, the heat pressing forming machines initialization is accomplished, and system is in ready state;

    Step 4, when the outside provided working signal, said device was received operating instruction, pressed down at a high speed, when pressing down stroke when arriving set speed rate conversion point position, continuation presses down at a slow speed, reaches one section die mould pressure up to system pressure, changes step 5 over to;

    Step 5, timing begins, and after first die mould period arrives, the control output quantity of torque will be updated to second section pressure size, and begin second section die mould timing;

    After second die mould period arrives, the control output quantity of torque will be updated to the 3rd section pressure size, and begin the 3rd section die mould timing;

    After the 3rd die mould period arrives, the control output quantity of torque will be updated to the 4th section pressure size, and begin the 4th section die mould timing;

    When the 4th section die mould timing then, change step 6 over to;

    Step 6, system switches to position control mode, returns and returns at a high speed through low speed successively, gets back to the reference position.
