The implementation principle of the hot pushing forming machine provided by the embodiment of the application is as follows: when an elbow is required to be machined by a hot-pushing forming machine, the cut pipe is sleeved on the core rod 12, then the push rod 24 is moved towards the direction close to the fixed plate 11, the push rod 24 drives the push block 21 to move towards the direction close to the fixed plate 11, the fixed rod 2 is moved into the through hole 16, then the rocking handle 76 is rotated, the rocking handle 76 drives the three screw rods 75 to rotate, the three screw rods 75 drive the moving frame 6 to move towards the direction close to the central axis of the core rod 12, the moving frame 6 drives the elbow forming part 3 to move, two clamping blocks 32 on the second semi-cylinder 31 are inserted into two clamping grooves 14 of the first semi-cylinder 13, then the push rod 24 is loosened, the push block 21 is moved towards the direction close to the clamping blocks 32 under the action of the elastic force of the spring 22, and the fixed rod 2 is inserted into the fixed hole 33, so that the elbow forming part 3 is fixedly connected with the core rod 12. Then the high-frequency induction heating equipment 4 is started, the high-frequency induction coil of the high-frequency induction heating equipment 4 carries out high-frequency heating on the elbow forming part 3, then the two air cylinders 52 are started simultaneously, the piston rods of the two air cylinders 52 push the push plate 53 to move towards the direction close to the moving frame 6, the push plate 53 pushes the pipe on the core rod 12 to move, and the pipe passes through the elbow forming part 3 to form an elbow. When the high-frequency induction coil of the high-frequency induction heating device 4 heats the elbow forming part 3 at high frequency, the temperature sensor 41 detects the temperature of the high-frequency induction coil of the high-frequency induction heating device 4, the temperature sensor 41 transmits the detected temperature signal to the controller 42, the controller 42 compares the received temperature signal with the set temperature signal, and when the detected temperature signal is larger than the maximum value of the set temperature signal, the controller 42 controls the high-frequency induction heating device 4 to be closed, so that the temperature on the high-frequency induction coil of the high-frequency induction heating device 4 is reduced, and the possibility that the whole hot-push forming machine is stopped when the hot-push forming machine is in operation due to overhigh temperature is reduced.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
