[0002] During the welding process of various circular materials such as tanks, steel pipes, and reactors, the welding materials need to be heated both before and after welding. The purpose of pre-weld heating is to reduce the temperature difference between the weld metal and the base material, reduce stress concentration, prevent cracks, and improve welding quality and performance; while the purpose of post-weld heating is to relax welding residual stress, stabilize the shape and size of the structure, improve the performance of the base material and weld joint, enhance the ability to resist stress corrosion, and further release harmful gases in the weld metal, especially hydrogen, to prevent the occurrence of delayed cracks.

[0003] The existing heating method mainly uses a wrapped heating belt and heats it through an induction heating device. However, since the shapes of the above-mentioned materials are generally circular or curved and the sizes are different, the traditional method of wrapping the heating belt mainly relies on manual work. The disassembly and assembly process is very time-consuming and labor-intensive, and various sizes of heating belts need to be prepared for different materials, resulting in unnecessary consumption of the heating belts, and poor flexibility and practicality in actual operation.

[0004] To this end, the present application proposes a device that can adapt to heating various circular or arc-shaped materials to solve the above problems. Utility Model Content

[0005] The cam is mounted on a support frame, and the support frame is connected to the support frame by a screw thread, and the support frame is connected to the support frame by a screw thread.

[0006] Furthermore, the adjusting screw passes through the front and rear sides of the fixing plate, the front end of the adjusting screw is rotatably connected to the adjusting rod, the front end of the adjusting rod is rotatably connected to the adjusting plate through a rotating support, and the rear end of the adjusting screw is provided with a handle.

[0007] Furthermore, the head and tail of each two adjustment plates are rotatably connected via a hinge.

[0008] Furthermore, casters are provided at each corner of the bottom of the base.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model can drive the heating component up and down by driving the motor, screw and slide seat, and then adjust its height to meet the heating needs of products of different heights. The curvature of the C-shaped heating belt can be adjusted by adjusting the screw to meet the heating needs of circular or arc-shaped products of different diameters. It is simple and convenient to use and has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0020] like Figure 1 As shown, the adjustable C-shaped welding heating device in this embodiment includes a base 1, a column 2, a drive motor 3, a screw 4, a slide 5 and a heating component 6. The column 2 is vertically arranged above the base 1, the drive motor 3 is arranged on the base 1 and is located on one side of the column 2, a slide groove 21 is provided in the column 2, the screw 4 is vertically arranged in the slide groove 21, the slide 5 can be slid up and down in the slide groove 21 and is connected to the screw 4 in a threaded manner, an opening 22 is provided on the front end face of the column 2 for the slide 5 to slide up and down, the heating component 6 is arranged on the outside of the column 2 and is connected to the slide 5, and casters 7 are provided at each corner of the bottom of the base 1. The casters 7 can adopt self-locking universal wheels to facilitate the movement and locking of the heating device.

[0021] The heating assembly 6 includes a fixed plate 61, multiple adjustment plates 62 and a heating belt 63. The fixed plate 61 is vertically arranged on the front side of the column 2 and is fixedly connected to the slide 5 through multiple connecting rods 64. Multiple adjustment plates 62 are arranged in a C shape on the front side of the fixed plate 61. Each adjustment plate 62 is movably connected to the fixed plate 61 through an adjusting screw 65. The adjusting screw 65 passes through the front and rear sides of the fixed plate 61. A heating belt 63 is provided on the front end face of each adjustment plate 62. The heating belt 63 is connected to the induction heating device through a power cord, and the heating temperature and heating time of the heating belt 63 are controlled by the induction heating device.

[0022] like Figure 2 As shown, the front end of the adjusting screw 65 is rotatably connected to the adjusting rod 66 , the front end of the adjusting rod 66 is rotatably connected to the adjusting plate 62 through a rotating support 67 , and the rear end of the adjusting screw 65 is provided with a handle 68 .
