[0043] In some embodiments, the pipe bending device further comprises a control circuit board 400, which is arranged in the accommodating cavity to control the heating temperature of the shaping component 200 and the cooling temperature of the cooling component 300; that is, the control circuit board 400 communicates with the cooling thermostat 304, the heating thermostat 204 and the cooling solenoid valve 303 respectively, and the pipe bending device is equipped with a switching power supply 600, which outputs 24V DC power to the control circuit board 400.

[0044] In some embodiments, the pipe bending device also includes a touch configuration screen 500, the touch configuration screen 500 is exposed on the pipe bending box 100, and the touch configuration screen 500 is connected to the control circuit board 400, for example, the touch configuration screen 500 communicates with the control circuit board 400 via RS485.

[0045] In some embodiments, the pipe bending box 100 includes a box cover 101 and a box body 102, wherein the box cover 101 is connected to the box body 102 to enclose the accommodating cavity, and the box body 102 is provided with a heat dissipation port. Exemplarily, the heat dissipation port includes a heat dissipation window 106 and a hot air outlet 107, wherein the heat dissipation window 106 and the hot air outlet 107 are arranged on the same side of the pipe bending box 100, and the hot air outlet 107 is used to correspond to the vortex tube 301; it should be noted that, in order to facilitate the control of the pipe bending device, a main power supply 108 is also provided on the box body 102, and the main power supply 108 is configured to provide electrical energy to the pipe bending device.

[0046] like Figure 1 as well as Figure 3As shown, the elbow box 100 further includes a safety structure, which is connected to the control circuit board 400 to lock the box cover 101 to the box body 102 . Exemplarily, the safety structure includes a manual fixing buckle 103, a safety lock 104 and a safety solenoid valve 105, the safety solenoid valve 105 communicates with the control circuit board 400, one side of the box cover 101 is rotatably connected to the box body 102, and the other side is provided with the manual fixing buckle 103 and the safety lock 104, wherein two manual fixing buckles 103 are provided, and the safety lock 104 is arranged between the two manual fixing buckles 103, when the start shaping button on the touch configuration screen 500 is clicked, the safety solenoid valve 105 is opened, the safety lock 104 is pressurized, and the cylinder is lifted to lock the box cover 101, when the temperature drops to the set safety temperature, the safety solenoid valve 105 is powered off, and its safety pin retraction protection is released, and the box cover 101 can be opened to check the shaping condition of the qualitative part.

A temperature sensor is installed on the shaping mold 201. After the heater 202 is heated to 220°C, the power supply and heating are stopped. At this time, the touch configuration screen 500 starts timing until the set insulation time of 5 minutes. Then the control circuit board 400 controls the refrigeration solenoid valve 303 to open, and the vortex tube 301 generates cold air to cool the shaping mold 201. When the temperature in the bending box 100 drops to the safe temperature of 30°C, the box cover 101 is opened to check the shaping condition of the shaped part.

[0048] In the above implementation process, the box cover 101 can be locked to the box body 102 through the safety structure. When the heating temperature does not drop to the safe temperature, the safety structure is always in a locked state to protect the safety of the operator.
