Description

Technical Field

[0001] This utility model relates to the field of induction heating technology, and in particular to a segmented induction heating belt that can be used in combination. Background Technology

[0002] Induction heating belts are electric heating belts used in conjunction with induction heating equipment. They have an internal induction coil structure and their heating principle is based on the induced current (eddy current loss) generated by the conductor under the action of a high-frequency magnetic field and the effect of the magnetic field inside the conductor (hysteresis loss) to cause the conductor to heat up. They are commonly used for preheating before welding and post-weld heat treatment of products such as steel structures, steel plates, metal pipes, and metal tanks.

[0003] Existing induction heating strips are generally monolithic structures, typically consisting of wires, a conductive plastic layer, an insulation layer, a shielding layer, and a sheath layer. Depending on the heating requirements of different products, the heating strip is manufactured in different lengths or widths and then applied to the product surface. However, this product-specific customization approach is inconvenient in practical use, has high manufacturing costs, and often cannot be reused, resulting in resource waste. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-2 As shown, the modular induction heating belt in this embodiment includes a fixing plate 1, a heating belt body 2, a crossbar 3, a longitudinal bar 4, a male connector 5, and a female connector 6. The heating belt body 2 is fixedly mounted on the front side of the fixing plate 1. Two longitudinal bars 4 are spaced apart on the rear side of the fixing plate 1. The crossbar 3 is connected to the two longitudinal bars 4 on both sides and extends to the outside of the fixing plate 1 at both ends. The fixing plate 1 is a straight plate, the crossbar 3 is a straight bar, and the heating belt body 2 is a planar rectangular structure, which can adapt to the heating needs of planar products such as steel structures and steel plates.

[0025] The male connector 5 is connected to one end of the heating element body 2 via a power cord, and the female connector 6 is connected to the other end of the heating element body 2 via a power cord.

[0026] The two ends of the longitudinal bar 4 are detachably connected to the fixing plate 1 by screws 7, and the two sides of the cross bar 3 are detachably connected to the middle position of the longitudinal bar 4 by hex bolts 8.

[0027] A magnet 9 is installed at each end of the crossbar 3, located outside the fixing plate 1. The outer end face of the magnet 9 does not extend beyond the outer end face of the heating belt body 2; that is, the outer end face of the magnet 9 is flush with or slightly lower than the outer end face of the heating belt body 2. Since the heating belt body 2 has a certain degree of flexibility and deformability, this arrangement ensures that when the magnet 9 is attracted to the metal (mainly steel) product to be heated, it exerts a certain amount of pressure on the heating belt body 2, causing it to adhere urgently to the product surface.

[0028] like Figure 3 As shown, in another embodiment, the fixing plate 1 is an arc-shaped plate, the crossbar 3 is an arc-shaped bar, and the heating belt body 2 adopts a corresponding arc-shaped rectangular structure, which can adapt to the heating needs of products with arc-shaped structures such as steel pipes and metal tanks.

[0029] like Figure 4 As shown, the male connector 5 includes a first connecting seat 51, a positioning post 52, and a three-phase copper rod 53. The rear end of the first connecting seat 51 is connected to the power cord. The positioning post 52 is located at the middle position of the front end of the first connecting seat 51. The three-phase copper rod 53 is located at the front end of the first connecting seat 51 and is symmetrically arranged around the positioning post 52.

[0030] The female connector 6 includes a second connector 61, a positioning groove 62, and a three-phase slot 63. The rear end of the second connector 61 is connected to the power cord. The positioning groove 62 is located at the middle position of the front end of the second connector 61. The three-phase slot 63 is located at the front end of the second connector 61 and is symmetrically arranged around the positioning groove 62.

[0031] like Figure 5 As shown, when the male connector 5 and the female connector 6 are plugged in, the positioning pin 52 is plugged into the positioning groove 62, and the three-phase copper rod 53 is plugged into the three-phase slot 63, thereby realizing the series connection of multiple induction heating belts, which can meet the heating needs of longer and larger products. One end of the male connector 5 or female connector 6 can be connected to the induction heating equipment to realize the power supply of the induction heating belt.

[0032] In summary, the induction heating belt of this utility model can be used individually or multiple induction heating belts can be combined by interlocking the male connector 5 and the female connector 6. The length and angle of the combined belt can be freely adjusted, making it highly flexible in use. It is also inexpensive to manufacture and can be reused, thus meeting the heating needs of various types of products.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
