The top of the high frequency heating machine 7 is provided with centralising device 14, and the centralising device 14 is light emitters, the light
The light directive workpiece of line transmitter；The light that the light emitters are sent is straight line, and the straight line is with bending in pressing mold 6
Heart line is in same perpendicular.
The length of the bending pressing mold 6 is matched with the angle of release length of workpiece 20 or conjunction angular length degree.
When needing to carry out angle of release to workpiece 20, the side of selection bottom is matched with domatic A, opposite side and horizontal plane
Angle be less than 45 degree of bending pressing mold 6, workpiece 20 is rule, the angle of release region and angle of release region of workpiece 20 is determined
Center line, domatic B18 is placed on towards in the region formed between the benchmark frame and fixed mount 16 of fixed mount 16 by workpiece 20, and
Ensure that workpiece 20 is fitted with the domatic A of fixed mount 16；Centralising device 14 is opened, that is, opens light emitters, the light transmitting
The light that device is sent projects the surface of workpiece 20, and rotary fixture substrate 15 and polymer product 20 make to project workpiece 20
Light is overlapped with drawn center line, and workpiece 20 is located at the underface for bending pressing mold 6；Two benchmark framves are adjusted again so that
The opposite face of benchmark frame is flushed with the angle of release regional edge edge of workpiece 20；Then high frequency heating machine 7 is started, leading screw 12 drives heating dish
Pipe A11 is then electrified to heating, heating coil A11 opening to workpiece 20 by way of heat radiation close to the bending side of workpiece 20
Angular zone is heated；After the temperature in the angle of release region of workpiece 20 reaches bending condition, leading screw 12 drives heating coil A11
Retract backward；Hydraulic stem 13, which drives, bends the angle of release region that pressing mold 6 is pressed downward workpiece 20, and workpiece 20 is located at the two ends in angle of release region
Part limited by benchmark frame and fixed mount 16, will not deform upon, the angle of release region of workpiece 20 due to not being supported, so
Outwards turned down in the presence of bending pressing mold 6, until the angle of release region of workpiece 20 is fitted with the opposite side of bending pressing mold 6 bottom；
Bending pressing mold 6 is retracted upwards in the presence of hydraulic stem 13, and the workpiece 20 after bending is taken out, and is prepared next workpiece 20 and is carried out
Angle of release.
When need to workpiece 20 carry out conjunction angle when, selection bottom side matched with domatic A, opposite side with it is domatic
The bending pressing mold 6 of C19 matchings, workpiece 20 is rule, and determines the center line for closing angular zone and conjunction angular zone of workpiece 20, will
Workpiece 20 is placed on domatic C19 towards in the region formed between the benchmark frame and fixed mount 16 of fixed mount 16, and ensures work
Part 20 is fitted with the domatic A of fixed mount 16；Centralising device 14 is opened, that is, opens light emitters, the light emitters are sent
Light project the surface of workpiece 20, rotary fixture substrate 15 and polymer product 20 make to project the light of workpiece 20 with
The center line drawn is overlapped, and workpiece 20 is located at the underface for bending pressing mold 6；Quantity and the position of benchmark frame are adjusted again, are made
Two outermost two sides of benchmark frame being fitted and connected successively are obtained to flush with the conjunction angular zone edge of workpiece 20；Then start
High frequency heating machine 7, leading screw 12 drives heating coil B11 ' close to the bending side of workpiece 20, is then electrified to heating, heating coil
B11 ' is heated by way of heat radiation to the conjunction angular zone of workpiece 20；When the temperature of the conjunction angular zone of workpiece 20 reach it is curved
After folding bar part, leading screw 12 drives heating coil B11 ' to retract backward；Hydraulic stem 13 drives bending pressing mold 6 to be pressed downward workpiece 20
Angular zone is closed, because workpiece 20 is angle steel, the side of angle steel two is mutually perpendicular to, and the domatic A of fixed mount 16 is with horizontal plane angle
45 degree, and workpiece 20 fits with the domatic A of fixed mount 16, thus be between workpiece 20 and the domatic C19 of benchmark frame it is hanging,
Also there is a certain distance junction between the bottom of workpiece 20 and benchmark frame and fixed mount 16；Angular region is closed because workpiece 20 is located at
The part in domain is limited by benchmark frame and fixed mount 16, is moved down and fold inward in the presence of bending pressing mold 6, until workpiece
20 conjunction angular zone is fitted with the opposite side of bending pressing mold 6 bottom；And the conjunction angular zone two side portions of workpiece 20 due to not by
To limitation, so will not also be deformed upon in the presence of bending pressing mold 6；Conjunction angular zone and bending pressing mold 6 bottom when workpiece 20
When the opposite side laminating in portion, bending pressing mold 6 is retracted upwards in the presence of hydraulic stem 13, and the workpiece 20 after bending is taken
Go out, prepare next workpiece 20 and carry out angle of release.
