Description
Technical field
The present invention relates to a kind of sleeve rotor end winding bending technology, relate in particular to a kind of large-size machine sleeve rotor end winding bending technology.
Background technology
At present the method that adopts of large-size machine sleeve rotor end winding bending is: hollow conductor carries out annealing in process earlier, make the hollow conductor deliquescing after recycling bending equipment carry out bending.Though the method bending is easy, the annealing softening before the bending can cause the coil rigidity to reduce, and makes the sleeve rotor coil yielding, has the hidden danger that the obstruction of rotor coil air channel or short trouble take place.The method need be equipped with annealing device and need annealing process procedure in addition, and production cost is higher.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and a kind of large-size machine sleeve rotor end winding bending technology is provided, and it has the annealing softening of need not, advantages of simple operation.
To achieve these goals, the present invention adopts following technical scheme:
A kind of large-size machine sleeve rotor end winding bending technology, concrete steps are:
Step 1: according to large-size machine sleeve rotor coil drawing data, set up the required database of bending equipment;
Step 2: access the database that needs the bending coil;
Step 3: need to select the coil of bending, and the bender of control full-automatic numerical control pipeline former moves to the position corresponding with wanting the bending loop length along guide rail;
Step 4: the coil of selecting is put into bracing frame, by hold-down mechanism fixed coil middle part, the two ends of the clamping device fixed coil by two ends;
Step 5: full-automatic numerical control pipeline former is to coil stepping bending;
Step 6: to stop at coil bending end no longer mobile when the pressure head of bender, and bending finishes, and the pressure head of control bender is kept in the center;
Step 7: after the coil bending finishes, be put into the coil situation behind the check bending on the mould, according to the basic volume under pressure of coil situation adjustment and error numerical value.
Bending equipment desired data is in the described step 1: the loop length of importing on the full-automatic numerical control pipeline former, bending radius, bending angle and the radius bend of setting at full-automatic numerical control pipeline former, bending angle, step angle, volume under pressure, pressure head drift angle, pressure head null value.
The concrete steps of described step 4 are: the coil of selecting is put into bracing frame, the hub of a spool borehole jack is on the bracing frame alignment pin, rotation is contained in the handle of the hold-down mechanism on the bracing frame, make the briquetting position of hold-down mechanism just in time be parked in directly over the coil, with spanner rotation briquetting double-screw bolt, the descending coil that compresses of briquetting is by this hold-down mechanism fixed coil middle part; The knob of the clamping device at rotation two ends is to coil side pressurization, utilizes the double-screw bolt of clamping device at spanner rotation two ends to pressurizeing above the coil, the two ends of the clamping device fixed coil by these two ends.
The concrete steps of described step 5 are: according to the step angle of setting in the step 1, bender rotates to the press-bending direction, when the anglec of rotation reaches the step angle of setting, pressure head presses down coil is carried out the bending first time, when reaching the volume under pressure of setting, pressure head rises, and bender rotates the step angle of a setting again to the press-bending direction, and pressure head presses down coil is carried out the bending second time; Laser range sensor on the pressure head is measured the springback capacity of coil, pressure head to coil after once volume under pressure repair according to the springback capacity after last time pressing down, the process pressure head is pressing down coil repeatedly, progressively finish the bending and forming of coil, bender no longer rotates when the press-bending direction rotates to maximum bending angle, and the position deviation of the coil of measuring when the laser sensor on the pressure head presses down bending and stop at coil bending end during less than set point no longer mobile for the last time.
Beneficial effect of the present invention: hollow conductor need not annealing softening before the large-size machine sleeve rotor end winding bending of the present invention, rigidity and the precision of coil have been guaranteed, annealing device and annealing process procedure have been removed, shortened technological process, reduced labour intensity, reduced production cost, easy and simple to handle, automaticity improves greatly.
