In this case, the stopper 70 is formed by a guide bar 71a through which a guide pin 73 protrudes from the stop pin 74 on one side of the frame 71 on which the air cylinder 72 is fixed. While maintaining a balance, it is connected to the rod 72a of the cylinder 72 to operate a predetermined width, and at the same time, the smooth pinch of the power supply ground pin 74 and the ground pin 74 inside the holder 73. Air pins 75 for operating the ground pin for each is provided.

The stopper block 80 corresponding to the stopper 70 includes a stop pin guide quench groove 81 and a power supply ground groove 82, respectively, which constitute a stop pin 74 formed on the stopper 70; The power supply ground pins 74 are inserted and installed, respectively, to prevent shaking of the thermocompression plate sets A, B, C, and D installed between the fixing bars 320 of the rotary rotating body 310, and at the same time, the necessary power is supplied internally. To be supplied together.

The rotary hot press of the steel door panel of the present invention configured as described above has a predetermined angle (120 ° to 90 ° intervals) at two rotary rotors 310 on both sides of the rotary shaft 300 that is provided in the form of a rotary between the side frames 201 and 202. The first, second and third thermocompression plates 10 between the holders 340 of the three to four thermocompression plate fixing bars 320 each of which are formed long, and the opposite side holders 340 'corresponding to the holders 340. The thermocompression plate sets (A, B, C, D), which are configured in multiple stages at a predetermined interval, are rotated 360 ° by the rotational drive of the rotary shaft 300 and the rotary drive 310 interlocked with the rotary drive 300. To make it rotate,

At this time, the holder 340 equipped with the first, second and third thermal compression plates 10, 20, and 30 is freely moved to the fixing protrusion 331 of the fixing rod 330 fixed to the rotary fixing bar 320. Since the pin is fitted so that the rotary rotor 310 is rotated / moved by driving, even if the angle and position change, the horizontal bar is maintained on the basis of the fixing rod 330.

The stop pin 74 of the stopper 70 provided on the side frames 201 and 202 is stopped at the selected position while the rotary rotor 310 is rotated to drive the quench of the quench block 80 provided at the rear end of the holder 340. The conveyor belt 25 is provided on the second and third thermocompression plates 20 and 30, respectively, so as to maintain a balance so as not to be shaken by being inserted into the groove 81. The door panel P to be supplied may be loaded into and seated on the second and third thermocompression plates 20 and 30, respectively.

As described above, when the door panel P is seated on the upper surfaces of the second and third thermal compression plates 20 and 30, the air cylinder mounted to the lower holder 340 of the third thermal compression plate 30.
