However, the device only places the hot plate mechanism on the support frame, and the milling mechanism still needs to be carried by people. In the document of full-automatic hot-melt welding machine performance index analysis and technical improvement of geotao, sudan and zuelan, 2016(6): 3238), a temperature sensor of a heating plate is generally arranged at a certain position in the heating plate, the temperature of a certain point of the heating plate is detected, and the working temperature displayed by a display is also the temperature of the point detected by the temperature sensor. The temperature of the point reaches the heating plate temperature range specified by the welding process, and the error range of the temperature of the point and the preset temperature of the heating plate is +/-5 ℃, which cannot represent that the temperature of any point on the heating plate meets the requirement. Therefore, the existing heating plate has the problem of uneven heating temperature.

Preferably, the bi-metallic strip is a composite material composed of two or more metals or other materials having suitable properties. The bimetallic strip is also called as a thermal bimetallic strip, and because the thermal expansion coefficients of all component layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip can bend towards one side of the passive layer, and the curvature of the composite material changes to generate deformation.
Preferably, the constant-temperature pumping device is filled with high-temperature-resistant heat-conducting liquid, has heating and pumping functions, maintains the temperature of the high-temperature-resistant heat-conducting liquid within a proper range through the heating function, and realizes the flow of the high-temperature-resistant heat-conducting liquid through the pumping function. Preferably, the high-temperature-resistant heat-conducting liquid is high-temperature-resistant oil liquid.
The working principle and the working process of the invention are as follows:
the device is used for pipeline welding. Firstly, respectively clamping two pipelines in two clamping mechanisms; because high-temperature-resistant heat-conducting liquid is not introduced, the cutter head 702 is in a milling state (namely an initial state) at the moment, the telescopic table 7021 is tightly attached to the bottom surface of the main body groove 7027-7 through the pulling force of the first return spring 7023, the milling cutter 7022 is in an extending state, the limiting block 7026 is extruded to the position under the milling cutter 7022 by the telescopic table 7021, meanwhile, the small boss 7026-4 supports and clamps the milling cutter 7022 to limit the movement of the milling cutter 7022, the milling cutter 7022 is prevented from retracting when the end surface of the pipeline is milled, and meanwhile, the second return spring 70210 is in a compressed state;
then, the motor 707 is electrified to rotate to drive the two-side cutter head 702 to rotate, and after the fixed rotating speed is reached, the two pipelines are tightly attached to the two end surfaces of the cutter head 702; the milling cutter 7022 continuously mills the end face of the pipeline under the action of rotation, and a part of space reserved by the sinking of the telescopic table 7021 serves as a chip cutting groove, so that chips are smoothly discharged; when there are continuous uniform chips, the cutter head 702 is separated from the pipe.
The motor 707 stops rotating after power is cut off, and after an operator checks that the milling of the two end surfaces is qualified, the cutter head 702 returns to the working position again, and the heating process starts; an external constant-temperature pumping device continuously provides power for high-temperature-resistant heat-conducting liquid through an internal pump, then the high-temperature-resistant heat-conducting liquid is introduced, flows into a liquid guide groove 7028 from a liquid inlet in a liquid conveying port 7029 through an external pipeline, a pipeline connector 701, an internal pipeline 705, an annular groove 708, a communication hole 706, a liquid conveying hole 714 and a pipeline butt joint 715, flows through a liquid return port in a liquid conveying port three 7027-9 to uniformly heat the cutter head main body, flows out from a liquid return port in a liquid conveying port three 7027-9 to a liquid inlet in a liquid conveying port two 7021-5 through a connecting hose 70212 to further flow into a liquid conveying groove of an expansion table 7021 to uniformly heat the expansion table 7021, and accordingly uniform heating of the surface of the whole cutter head is completed; and the liquid flows back to the constant-temperature pumping device through a liquid return port in the second infusion port 7021-5, a connecting hose 70212, a liquid inlet in the third infusion port 7027-9, a liquid guide groove 7028, a liquid return port in the first infusion port 7029, a pipeline butt joint 715, an infusion hole 714, a communication hole 706, an annular groove 708, an internal pipeline 705, a pipeline interface 701 and an external pipeline to form circulation.
After the cutter head 702 is heated, the small bimetallic strip 7024 and the large bimetallic strip 7025 are arched due to thermal deformation, the large bimetallic strip 7025 jacks up the telescopic table 7021, and the telescopic table 7021 can only move upwards along the side face of the main body groove 7027-7 under the action of a moving pair consisting of the second groove 7027-1 and the first rail 7021-2; while the telescopic table 7021 moves upwards, the first return spring 7023 is stretched; because the limit block 7026 can only move along the bottom surface of the main body groove 7027-7, when the telescopic table 7021 moves upwards, the first groove 7021-1 is matched with the second rail 7026-1, so that the contact surface between the telescopic table 7021 and the limit block 7026 is tightly moved, the limit block 7026 is pulled to move, and the compressed second return spring 70210 provides power for the limit block 7026 to ensure the movement; along with the movement of the limit block 7026, the second return spring 70210 is in a natural state and restores to the original length, the milling cutter 7022 is separated from the limit of a small boss 7026-4 on the limit block 7026, a small bimetallic strip 7024 arches, so that the milling cutter 7022 moves away from the boss 7027-5, and the third return spring 70211 is compressed; when the temperature reaches the set temperature, the extension table 7021 extends flush with the surface of the main body 7027 of the cutter head, and the milling cutter 7022 is retracted into the main body slot 7027-7.
Then, the two pipelines are tightly attached to the two end surfaces of the cutter head 702 again and keep a certain pressure, and the end surfaces of the pipelines begin to absorb heat and melt to become soft; when the heat absorption time is up, separating the cutter head 702 from the pipe fitting, taking the cutter head 702 away, rapidly butting the two pipelines, keeping a certain pressure, and waiting for the pipelines to be cooled; the constant-temperature pumping device stops conveying the high-temperature-resistant heat-conducting liquid, switches to conveying air, and recovers the high-temperature-resistant heat-conducting liquid in the cutter head 702 and the pipeline to the constant-temperature pumping device; after the cutter head 702 is gradually cooled, the small bimetallic strip 7024 and the large bimetallic strip 7025 recover to the original shapes, the first return spring 7023 provides a pulling force to retract the telescopic table 7021, the limiting block 7026 is extruded to move the limiting block 7026 in the opposite direction, and the second return spring 70210 is continuously compressed by the extrusion action of the limiting block 7026; the third return spring 70211 is in a natural state and restores the original length, the milling cutter 7022 is jacked up, the milling cutter 7022 extends out, and the cutter head 702 is restored to the initial state.
And after the pipeline is cooled, the pipeline is disassembled, and the welding is finished.
Nothing in this specification is said to apply to the prior art.
