Description
Technical field
The present invention relates to a kind of sleeve rotor end turn bending technique, particularly relate to a kind of large-size machine sleeve rotor end turn bending technique.
Background technology
The method that current large-size machine sleeve rotor end turn bending adopts is: hollow core conductor first carries out annealing in process, recycles bending shape device and carry out bending after making hollow core conductor deliquescing.Although the method bending is easy, the annealing softening before bending can cause coil rigidity to reduce, and makes sleeve rotor coil yielding, there is the hidden danger that the blocking of rotor coil air channel or short trouble occur.The method need be equipped with annealing device and need annealing process procedure in addition, and production cost is higher.
Summary of the invention
Object of the present invention is exactly that provide a kind of large-size machine sleeve rotor end turn bending technique, it has without the need to annealing softening, advantage easy and simple to handle in order to solve the problem.
To achieve these goals, the present invention adopts following technical scheme:
A kind of large-size machine sleeve rotor end turn bending technique, concrete steps are:
Step one: according to large-size machine sleeve rotor coil drawing data, set up the database needed for bending shape device;
Step 2: recall the database needing bending coil;
Step 3: select the coil needing bending, and the bender controlling full-automatic numerical control pipeline former moves to the position corresponding with wanting bending loop length along guide rail;
Step 4: the coil of selection is put into bracing frame, in the middle part of hold-down mechanism fixed coil, by the two ends of the clamping device fixed coil at two ends;
Step 5: full-automatic numerical control pipeline former is to coil step-by-step movement bending;
Step 6: no longer move when the pressure head of bender stops at coil bending end, bending terminates, and the pressure head controlling bender is kept in the center;
Step 7: after coil bending terminates, is put into the coil situation after mould checking bending, adjusts basic volume under pressure and error value according to coil situation.
In described step one, bending shape device desired data is: the loop length that full-automatic numerical control pipeline former inputs, bending radius, bending angle and the radius bend set on full-automatic numerical control pipeline former, bending angle, stepping angle, volume under pressure, pressure head drift angle, pressure head null value.
The concrete steps of described step 4 are: the coil of selection is put into bracing frame, hub of a spool borehole jack is on bracing frame alignment pin, rotate the handle of the hold-down mechanism be contained on bracing frame, the briquetting position of hold-down mechanism is just in time parked in directly over coil, briquetting stud is rotated with spanner, the descending coil pressing of briquetting, in the middle part of this hold-down mechanism fixed coil; The knob rotating the clamping device at two ends is to coil lateral pressurization, and the stud utilizing spanner to rotate the clamping device at two ends pressurizes to above coil, by the two ends of the clamping device fixed coil at these two ends.
The concrete steps of described step 5 are: according to the stepping angle of setting in step one, bender rotates to press-bending direction, when the anglec of rotation reaches the stepping angle of setting, pressure head presses down and carries out first time bending to coil, when reaching the volume under pressure of setting, pressure head rises, and bender rotates the stepping angle of a setting again to press-bending direction, pressure head presses down and carries out second time bending to coil; The springback capacity of the laser range sensor measuring coil on pressure head, pressure head is repaired according to the springback capacity after previous pressing down volume under pressure once after coil, through pressure head pressing down repeatedly to coil, progressively complete the bending and forming of coil, bender no longer rotates when press-bending direction rotates to maximum bending angle, presses down bending for the last time and stops at coil bending end no longer move when the position deviation of the coil that the laser sensor on pressure head is measured is less than setting value.
Beneficial effect of the present invention: before large-size machine sleeve rotor end turn bending of the present invention, hollow core conductor is without the need to annealing softening, ensure that rigidity and the precision of coil, eliminate annealing device and annealing process procedure, shorten technological process, reduce labour intensity, reduce production cost, easy and simple to handle, automaticity improves greatly.
