Examples
The invention discloses a heat treatment device for a bimetal composite pipe, which is used for carrying out heat treatment on the bimetal composite pipe and overcomes the defect that the traditional bimetal composite pipe cannot carry out heat treatment on an inner pipe or an outer pipe independently. The heat treatment device for the bimetal composite pipe comprises a device main body for electromagnetic induction heating and a heat treatment packaging cylinder matched with the bimetal composite pipe for use. The device main body of the non-contact heating mode is skillfully combined with the heat treatment packaging cylinder which can cool down the single side of the bimetal composite pipe, so that the function of independently carrying out heat treatment on the outer pipe and the inner pipe of the bimetal composite pipe is realized.
Specifically, the device main body is provided with a machine table 1. The machine table 1 is provided with a heating channel. The heating channel is of a straight structure, and the corresponding positions at the two ends of the heating channel are respectively provided with a feed hole 2 and a discharge hole. The bimetal composite pipe to be heat-treated enters the machine table 1 from the feeding hole 2, moves along the heating channel, and is moved out from the discharging hole after heat treatment. An electromagnetic induction heating mechanism is installed on the heating channel, and the bimetallic composite tube is heated by matching the induction heating coil 7 with high-frequency changing current by adopting the electromagnetic induction principle. Preferably, the electromagnetic induction heating mechanism includes an induction heating coil 7 fitted outside the heating passage, and a high-frequency heater 8 for driving and controlling the induction heating coil 7. The induction current in the induction heating coil 7 is controlled by the high-frequency heater 8, thereby adjusting the heating power. For example, the electromagnetic induction heating mechanism comprises an induction heating coil 7 which is sleeved outside the heating channel, and a high-frequency heater 8 which drives and controls the induction heating coil 7. The electromagnetic induction heating mechanism belongs to the existing equipment and structure, is completely similar to the principle of an induction cooker, and is not repeated. In order to drive the bimetal composite pipe to move along the heating channel, a driving mechanism is arranged on the machine table 1. The specific structure of the driving mechanism is not limited as long as the driving mechanism can realize linear motion driving, such as a conventional linear motion pair, a linear cylinder or a linear motion motor. The driving mechanism preferably used in the present application comprises a driving roller 5 installed on the heating channel and a driving motor 3 for driving the driving roller 5 to rotate. The driving roller 5 is driven to rotate by the driving motor 3, so that linear driving is realized. The driving roller 5 can be made of ceramic material or other insulating high-temperature resistant material. Specifically, as shown in fig. 1, the driving mechanism includes a driving motor 3, a driving shaft 4, a driving roller 5, a driven shaft, and a driven roller 6. The driving motor 3 is connected with the driving shaft 4 through a belt to drive the driving shaft 4 to rotate. The driving shaft 4 is arranged on the machine table 1 perpendicular to the length direction of the heating channel. The driving roller 5 which rotates synchronously with the driving shaft 4 is arranged on the driving shaft 4. The driving roller 5 is in contact with the heat treatment packaging barrel and drives the heat treatment packaging barrel to move along the heating channel through rotation. A driven shaft parallel to the driving shaft 4 is also arranged on the machine table 1. A driven roller 6 is mounted on the driven shaft. The driven roller 6 cooperates with the driving roller 5 to limit the heat treatment packaging cylinder from moving along the heating channel, for example, the driving roller 5 and the driven roller 6 are arranged at intervals. 1 initiative gyro wheel 5 and 1 driven roller 6 are 1 group, can adjust the arrangement according to actual conditions, can be 1 or multiunit. The middle of the driving roller 5 and the driven roller 6 can be of a concave structure, so that the stability of the heat treatment packaging cylinder during movement can be better ensured.
Referring to fig. 2, the heat treatment packaging cylinder includes a sealing cylinder 9 coaxially disposed with the bimetal composite tube and sleeved outside the bimetal composite tube, and sealing end caps 10 installed at two ends of the sealing cylinder 9. The sealing end cover 10 is in sealing contact with the bimetal composite pipe, so that the inner side and the outer side of the pipe wall of the bimetal composite pipe are isolated from each other, and an outer cooling water channel enclosed by the sealing cylinder 9, the sealing end cover 10 and the bimetal composite pipe and an inner cooling water channel enclosed by the bimetal composite pipe and the sealing end cover 10 are formed. The sealing cylinder 9 is made of insulating heat-resistant material, preferably high-temperature-resistant ceramic material. The heat resistance here is only required to be satisfied so that the sealing cylinder 9 can maintain a good durability regardless of the heat treatment of the inner tube or the outer tube.

In order to further optimize the heat treatment process, expand the application range of the heat treatment process and improve the adjustability and the flexibility, the invention controls the heat treatment process parameters by the heating power of the electromagnetic induction heating mechanism and the speed of the driving mechanism driving the heat treatment packaging cylinder to move along the heating channel, namely the electromagnetic induction heating mechanism adjusts the heat treatment temperature, and the driving mechanism controls the heat treatment time. And water is respectively supplied to the outer cooling water channel and the inner cooling water channel through a water pump, and the flow rate of cooling water is controlled through the water pump.
