Description
技术领域technical field
本实用新型涉及高频感应加热技术领域，具体而言，涉及一种感应加热器。The utility model relates to the technical field of high-frequency induction heating, in particular to an induction heater.
背景技术Background technique
高频感应加热技术的理论基础是法拉第电磁感应定律、焦耳定律、集肤效应和热传导理论。感应加热时，加热电源将常用的工频电源转换成100HZ或者更高频率的高频电源。高频电流通过线圈产生交变磁场，当磁场内磁力线圈通过待加热金属工件时，交变的磁力线穿透金属工件形成回路，在其横截面内产生感应电流，此电流称为涡流。在焦耳定律原理的作用下，工件迅速发热，进而达到加热实现焊接的目的。The theoretical basis of high-frequency induction heating technology is Faraday's law of electromagnetic induction, Joule's law, skin effect and heat conduction theory. During induction heating, the heating power supply converts the commonly used industrial frequency power supply into a high-frequency power supply with a frequency of 100HZ or higher. High-frequency current passes through the coil to generate an alternating magnetic field. When the magnetic coil in the magnetic field passes through the metal workpiece to be heated, the alternating magnetic force lines penetrate the metal workpiece to form a loop, and an induced current is generated in its cross section. This current is called eddy current. Under the action of the principle of Joule's law, the workpiece heats up rapidly, and then achieves the purpose of heating and welding.
感应加热器是利用上述原理对工件实现加热的一种设备。目前，对于形状简单的工件，如圆柱形工件，可以采用常规的线圈式的感应加热器加热即可。但是，对复杂工件只能采用“U”型感应加热器进行加热，该种感应加热器只适用于尺寸规格为12mm及小于12mm的工件。而对于规格大于12mm的复杂工件，“U”型感应加热器会存在加热不均匀和加热效率低等问题。The induction heater is a device that uses the above principles to heat the workpiece. At present, for workpieces with simple shapes, such as cylindrical workpieces, conventional coil-type induction heaters can be used for heating. However, only "U" type induction heaters can be used for heating complex workpieces, and this induction heater is only suitable for workpieces with a size of 12mm and less than 12mm. For complex workpieces with specifications greater than 12mm, the "U"-shaped induction heater will have problems such as uneven heating and low heating efficiency.

The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
为了使本技术领域的人员更好地理解本实用新型方案，下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分的实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本实用新型保护的范围。In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the utility model. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
如图1和图2所示，本实施例的感应加热器包括第一感应器10和第二感应器20。其中，第一感应器10相对于第二感应器20可活动的设置。感应加热器包括第一感应器10和第二感应器20相对闭合并形成加热空间的第一状态，以及第一感应器10和第二感应器20相对分离的第二状态。As shown in FIGS. 1 and 2 , the induction heater of this embodiment includes a first inductor 10 and a second inductor 20 . Wherein, the first sensor 10 is movable relative to the second sensor 20 . The induction heater includes a first state in which the first inductor 10 and the second inductor 20 are relatively closed to form a heating space, and a second state in which the first inductor 10 and the second inductor 20 are relatively separated.
应用本实施例的技术方案，在对形状复杂的工件50进行加热时，先将第一感应器10和第二感应器20中的一个置于工件50中需要进行加热部位，再闭合第一感应器10和第二感应器20，使待加热工件50位于闭合的加热空间中。这样，通过打开和闭合感应加热器，就可以对形状复杂的工件50在需要加热的部位进行加热。由于待加热的部位处于闭合的加热空间中，待加热的部位处就会产生分布比较均匀的感生电流，这样待加热的部位的发热就会比较均匀。同时，整个待加热的部位都处于加热空间中，增大了可以产生感生电流的导体体积，提高了加热效率。Applying the technical solution of this embodiment, when heating a workpiece 50 with a complex shape, first place one of the first inductor 10 and the second inductor 20 in the workpiece 50 to be heated, and then close the first inductor The device 10 and the second inductor 20 make the workpiece 50 to be heated located in a closed heating space. In this way, by turning on and off the induction heater, the workpiece 50 with complex shape can be heated at the position to be heated. Since the part to be heated is in a closed heating space, an induced current with relatively uniform distribution will be generated at the part to be heated, so that the heating of the part to be heated will be relatively uniform. At the same time, the entire part to be heated is in the heating space, which increases the volume of the conductor that can generate the induced current and improves the heating efficiency.
如图1所示，在本实施例中，第一感应器10包括呈半环形的第一加热部件11。半环形的第一加热部件11可以更贴近于圆形的待加热工件50，利于待加热的工件50中产生感生电流。优选地，第二感应器20包括呈半环形的第二加热部件。使得整个感应加热器都更贴近与圆形的待加热工件50，更有利于待加热的工件50中产生感生电流。As shown in FIG. 1 , in this embodiment, the first inductor 10 includes a semi-circular first heating component 11 . The semi-circular first heating component 11 can be closer to the circular workpiece 50 to be heated, which is beneficial to generate an induced current in the workpiece 50 to be heated. Preferably, the second inductor 20 includes a semi-circular second heating component. The entire induction heater is closer to the circular workpiece 50 to be heated, which is more conducive to the generation of induced current in the workpiece 50 to be heated.
如图2所示，在本实施例中，感应加热器位于第一状态时，第一加热部件11和第二加热部件21组合成一个闭合圆环。这样，完整圆形的感应加热器对于圆形的待加热工件50的加热效果会更好。As shown in FIG. 2 , in this embodiment, when the induction heater is in the first state, the first heating component 11 and the second heating component 21 are combined to form a closed circle. In this way, the completely circular induction heater has a better heating effect on the circular workpiece 50 to be heated.

如图1和图2所示，第一感应器10还包括与第一加热部件11两端连接的第一连接管12和第二连接管13，第二感应器20还包括与第二加热部件21两端连接的第三连接管22和第四连接管23，第一连接块14设置在第一连接管12上，第二连接块24设置在第三连接管22上。这样，使得本实施例的感应加热器结构简单，使用方便。As shown in Figures 1 and 2, the first inductor 10 also includes a first connecting pipe 12 and a second connecting pipe 13 connected to both ends of the first heating part 11, and the second inductor 20 also includes a connecting pipe connected to the second heating part 11. 21 A third connecting pipe 22 and a fourth connecting pipe 23 connected at both ends, the first connecting block 14 is arranged on the first connecting pipe 12 , and the second connecting block 24 is arranged on the third connecting pipe 22 . In this way, the structure of the induction heater of this embodiment is simple and easy to use.
如图2和图3所示，在本实施例中，感应加热器还包括连接件30，感应加热器位于第一状态时，连接件30连接第一感应器10和第二感应器20。在加热时，感应加热器就可以稳定地处于第一状态，保障形成闭合的加热空间以便于对工件50进行均匀的加热。As shown in FIG. 2 and FIG. 3 , in this embodiment, the induction heater further includes a connecting piece 30 , and when the induction heater is in the first state, the connecting piece 30 connects the first inductor 10 and the second inductor 20 . During heating, the induction heater can be stably in the first state, ensuring the formation of a closed heating space so as to uniformly heat the workpiece 50 .
具体地，在本实施例中，如图2和图3所示，连接件30包括第三连接块31、第四连接块32以及连接第三连接块31和第四连接块32的紧固销33，第三连接块31设置在第一感应器10上，第四连接块32设置在第二感应器20上与第三连接块31对应的位置处。通过紧固销33与感应加热器的配合就可以简单而方便地实现感应加热器的闭合。Specifically, in this embodiment, as shown in FIGS. 2 and 3 , the connector 30 includes a third connecting block 31 , a fourth connecting block 32 and fastening pins connecting the third connecting block 31 and the fourth connecting block 32 33 , the third connection block 31 is disposed on the first inductor 10 , and the fourth connection block 32 is disposed on the second inductor 20 at a position corresponding to the third connection block 31 .
