Specific embodiment
It will describe in detail in conjunction with specific embodiments with reference to the accompanying drawings below.
A kind of device in diminution bend pipe aperture as shown in Figure 1, 2, including driving device (50), bend pipe 1 and fixing seat 2,
It is provided with heating element 8 in fixing seat 2, heat insulation pressure-resistant component 4 is enclosed on the outside of heating element 8, driving device is connected with automatically
Heating device and automatic extrusion device 9, automatic extrusion device 9 are arranged in around heat insulation pressure-resistant component 4;
Automatic heating device includes that the heater 5 to form closed loop configuration, high temperature detector 6, relay 7 and heating are connected with conducting wire
Element 8;
Through-hole is equipped in fixing seat 2,6 or 6 or more are equipped in through-hole to be fan-shaped heating unit to the mobile cross section of axis
Part 8, it is 6 that cross section, which is fan-shaped heating element 8, in this implementation;
Heating element 8 in through-hole divides for former and later two parts, first half total one diameter of synthesis of heating element 8 and pipe fitting
The through-hole that 1 outer diameter matches, the total heating element 8 of latter half synthesize the through-hole that a diameter is less than 1 outer diameter of pipe fitting.
The working principle of this programme is: fixing seat 2 fix be arranged on heating element 8 and heating element 8 it is heat-insulated anti-
Splenium part 4, driving device 50 drive heater 5 to heat heating element 8, and high temperature detector 6 persistently examines heating element 8
It surveys, when the temperature change for detecting heating element 8 reaches preset numerical value, relay 7 controls heater 5 to heating element 8
It carries out heating or power down process, 1 nozzle of bend pipe for needing to reduce is placed in the open circles of heating element 8, driving device 50
Driving automatic extrusion device 3 carries out fastening extruding to heating element 8, to squeeze excessive 1 nozzle of bend pipe in aperture, bend pipe at this time
1 nozzle generates phase transformation under the action of 8 heat transmitting of heating element, and principle easy to process when using metal phase change reduces bend pipe 1
Nozzle.
