Description

Technical Field

[0001] The utility model relates to the technical field of bucket tooth welding, in particular to a bucket tooth welding preheating device. Background Art

[0002] Bucket tooth welding preheating device is usually used for excavator bucket teeth pre-welding treatment to improve welding quality. Preheating before welding can reduce the cooling rate of the weld, drive off moisture, and help prevent the possibility of hydrogen accumulation and cracking. The traditional process uses flame heating for preheating, but this method has problems of uneven heating and time-consuming and labor-intensive. Modern technology tends to use induction heating, which heats evenly, quickly and efficiently, and does not require human intervention, thereby improving production efficiency and heating effect.

[0003] However, most of the devices in modern processes are fixed and immovable, and the connection operations need to be performed at different locations. The immovable preheating device may require the operator to move the bucket teeth to the preheating area, which increases labor intensity and time cost. Utility Model Content

[0007] As a further improvement of the present invention, the inductor coil is wound on the outer side wall of the iron core, and two wire ends of the inductor coil extend and are connected to the control box.

[0008] As a further improvement of the utility model, the fixing mechanism includes a fixing plate fixedly connected to the outer wall of the core, the fixing plate is connected to the base via bolts, and one end of the bolt passes through the fixing plate and is threadedly connected to the base.

[0009] As a further improvement of the present invention, the supporting mechanism includes a fixing frame fixedly connected to the base, a crank is provided above the fixing frame, a threaded rod is fixedly connected to the bottom of the crank, an end of the threaded rod away from the crank passes through the fixing frame and the base and is rotatably connected to a rotating shaft, and an end of the rotating shaft away from the threaded rod is fixedly connected to a supporting block.

[0010] As a further improvement of the utility model, thread grooves are provided on both sides of the upper end of the base, and the threaded rod is threadably connected to the thread grooves.

[0011] As a further improvement of the present invention, the support block is a rectangular block, and both ends of the bottom of the support block have arc surfaces.

[0012] Beneficial effects of the utility model:

[0013] By setting up an iron core, an inductor coil, a control box and a display screen, and connecting the inductor coil through the control box, eddy currents are generated in the bucket teeth inside the iron core, and rapid and uniform heating of the bucket teeth is achieved through the principle of electromagnetic induction. At the same time, the display screen can display the current temperature in real time, achieving precise temperature control and real-time monitoring, ensuring a safe and effective heating process.
