Description

Technical Field

[0001] The utility model relates to the field of roller induction heating devices, in particular to an induction heating execution device for rollers. Background Art

[0002] When processing plates, strips, foils and other materials through roller pressing, a large amount of heat will be released during the extrusion and deformation process of the materials, causing the rollers to heat up. Moreover, the heat received in the middle of the roller is much greater than that at both ends of the roller, which will cause the middle of the roller to expand and deform due to heat, affecting the rolling effect. Therefore, it is necessary to heat both ends of the roller to ensure that the temperature of the roller as a whole is uniform. Usually, an induction heating device is used, which drives two induction heating moving positions through the cooperation of transverse and longitudinal slide rails and approaches the two ends of the roller respectively. The existing heating actuator adopts the method of electric control + hydraulic cylinder drive. Since the use of hydraulic drive requires the configuration of a hydraulic station, additional investment is required, and the system is relatively complex. The transmission accuracy of the hydraulic drive is insufficient, and it is difficult to control the movement speed. It is difficult to achieve the precise positioning function required by the process. The structure is complex, the volume is large, the cost is high, the installation is difficult, the maintenance is inconvenient, the reliability is poor, and the operating efficiency is low. Utility Model Content

[0005] A screw rod is installed inside the transverse driving mechanism, and the length direction of the screw rod of the transverse driving mechanism is parallel to the length direction of the transverse slide rail. A numerical control electric drive motor for driving the screw rod to rotate is installed at one end of the transverse driving mechanism. A transverse slider is provided on the upper surface of the transverse driving mechanism. The bottom ends of the two transverse sliders are respectively connected to the screw rods of the two transverse driving mechanisms, and the top ends of the two transverse sliders are respectively connected to the bottom ends of the two longitudinal driving mechanisms.

[0006] A screw rod is installed inside the longitudinal drive mechanism, and the length direction of the screw rod of the longitudinal drive mechanism is perpendicular to the length direction of the transverse slide rail. A CNC electric drive motor for driving the screw rod to rotate is installed at the end of the longitudinal drive mechanism away from the roller. An induction heating module is provided on the upper surface of the longitudinal drive mechanism, and the bottom ends of the two induction heating modules are respectively connected to the screw rods of the two longitudinal drive mechanisms.

A longitudinal drive mechanism is slidably arranged above two transverse slide rails of the same group, and another longitudinal drive mechanism is slidably arranged above two transverse slide rails of another group.

[0008] According to the above technical solution, the beneficial effects of the utility model are:

[0009] The transverse drive mechanism and the longitudinal drive mechanism of the utility model both adopt the CNC electric drive motor + screw transmission mode, which can realize synchronous control through the CNC electric drive motor controller, and realize the precise transverse and longitudinal movement of the heating terminal of the variable frequency induction heating actuator. When the induction heating terminal approaches the magnetic conductive working surface, the heating effect can be generated by induction variable frequency electromagnetic eddy current, thereby meeting the process requirements. Compared with the prior art that adopts the electric control + hydraulic cylinder drive mode, the utility model does not need to configure a hydraulic station, does not require additional investment, and has a simple system. The CNC electric drive motor and screw can greatly improve the transmission accuracy, meet the precise positioning function required by the process, and accurately control the movement speed. It has a simple structure, a small size, and a low cost. It can realize modular installation, convenient maintenance, and high reliability, and effectively improves the adaptability to the binding operation environment and the operating efficiency.

[0013] With reference to the accompanying drawings, the specific implementation is as follows:

[0014] like Figure 1-2 As shown, an induction heating actuator for a rolling mill roll comprises a frame 2 arranged on one side of a group of rolling mill rolls 1 along a radial direction, a transverse slide rail 3 is arranged on the upper surface of the frame 2, the length directions of the frame 2 and the transverse slide rail 3 are parallel to the axial direction of the rolling mill roll 1, transverse drive mechanisms 4 are respectively arranged on both sides of the frame 2 along the width direction, and two longitudinal drive mechanisms 5 are slidably arranged in parallel with each other on the slide rail.

[0015] like Figure 2As shown, a screw rod is installed inside the transverse driving mechanism 4, and the length direction of the screw rod of the transverse driving mechanism 4 is parallel to the length direction of the transverse slide rail 3. A CNC electric drive motor 6 for driving the screw rod to rotate is installed at one end of the transverse driving mechanism 4. A transverse slider 7 is provided on the upper surface of the transverse driving mechanism 4. The bottom ends of the two transverse sliders 7 are respectively connected to the screw rods of the two transverse driving mechanisms 4, and the top ends of the two transverse sliders 7 are respectively connected to the bottom ends of the two longitudinal driving mechanisms 5.

[0016] like Figure 2 As shown, a screw rod is installed inside the longitudinal driving mechanism 5, and the length direction of the screw rod of the longitudinal driving mechanism 5 is perpendicular to the length direction of the transverse slide rail 3. A CNC electric drive motor 6 for driving the screw rod to rotate is installed at one end of the longitudinal driving mechanism 5 away from the roller 1. An induction heating module 8 is provided on the upper surface of the longitudinal driving mechanism 5, and the bottom ends of the two induction heating modules 8 are respectively connected to the two screw rods of the longitudinal driving mechanism 5.

[0017] like Figure 2 As shown, the frame 2 used in this embodiment is a metal structure made of aluminum alloy or square steel, and four transverse rails 3 are provided on the upper surface of the frame 2. One longitudinal drive mechanism 5 is slidably arranged above two transverse rails 3 of the same group, and another longitudinal drive mechanism 5 is slidably arranged above two transverse rails 3 of another group. By dividing the transverse rails 3 into two groups, the total length of the transverse rails 3 is reduced, saving costs; and each longitudinal drive mechanism 5 is arranged on two transverse rails 3 of the same group, which improves the movement accuracy of the longitudinal drive mechanism 5 along the transverse rails 3.

[0018] In this embodiment, both the transverse drive mechanism and the longitudinal drive mechanism adopt a CNC electric drive motor + screw transmission method, and synchronous control can be achieved through a CNC electric drive motor controller to achieve precise transverse and longitudinal movement of the heating terminal of the variable frequency induction heating actuator. When the induction heating terminal approaches the magnetic working surface, a heating effect can be generated by inducing variable frequency electromagnetic eddy currents, thereby meeting the process requirements. There is no need to configure a hydraulic station. The CNC electric drive motor and screw can greatly improve the transmission accuracy, meet the precise positioning function required by the process, and accurately control the movement speed. It has a simple structure, a small size, and a cost advantage. It can be modularly installed, easy to maintain, and has high reliability.
