Description

Technical Field

[0001] This invention relates to the field of induction heating technology for metal materials, and in particular to an adjustable magnetic flux density high-efficiency transverse magnetic inductor for heating irregular edges of metal plates. Background Technology

[0002] In the field of sheet metal processing, heat treatment is an important means to improve the performance of sheet metal, and electromagnetic induction heating technology is widely used. However, localized heating, especially for irregularly shaped materials, has always been a difficult problem to solve in the metal material induction heating industry. Typical inductor winding methods involve single or multiple turns of copper tube wound into circular or rectangular coils, which cannot achieve precise localized heating for the irregular edges of sheet metal.

[0003] Therefore, developing a device that can flexibly adjust the magnetic flux density according to the irregular edge shape of a metal sheet to achieve precise local heating has important practical significance and urgent market demand. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable magnetic flux density high-efficiency transverse magnetic inductor for heating irregularly shaped edges of metal sheets, which can accurately heat irregularly shaped edges, reduce energy consumption, increase yield, and improve product quality.

[0005] To achieve the above objectives, the present invention provides an adjustable magnetic flux density high-efficiency transverse magnetic inductor for heating irregular edges of metal plates, comprising an inductor body one and an inductor body two symmetrically arranged vertically; the inductor body one includes a straight copper tube one and an adjustable magnetic flux density focusing structure one, the adjustable magnetic flux density focusing structure one being disposed on the straight copper tube one; the inductor body two includes a straight copper tube two and an adjustable magnetic flux density focusing structure two, the adjustable magnetic flux density focusing structure two being disposed on the straight copper tube two, and the inductor body one and the inductor body two are connected in series through a water-cooled copper plate.

[0006] Preferably, a straight copper tube is symmetrically provided with a bent copper tube on both sides, and a straight copper tube is symmetrically provided with a bent copper tube on both sides.

[0007] Preferably, the straight copper tube one and the bent copper tube one are integrated into one structure, and the straight copper tube two and the bent copper tube two are integrated into one structure.

[0008] Preferably, straight copper tube one, bent copper tube one, straight copper tube two, and bent copper tube two are oxygen-free copper tubes.

[0009] Preferably, an irregularly shaped edge metal plate is provided between the first straight copper tube and the second straight copper tube.

[0010] Preferably, cooling water inlets are provided on both the first and second bent copper pipes.

[0011] Preferably, the first bent copper tube and the second bent copper tube are connected to the water-cooled coaxial cable of the IGBT induction heating power supply.

[0012] Preferably, the adjustable magnetic flux density magnetic focusing structure one is connected to the sensor frame one via connecting bolts, and the adjustable magnetic flux density magnetic focusing structure two is connected to the sensor frame two via connecting bolts.

[0013] Preferably, sensor frame one and sensor frame two are configured as I-shaped, and sensor frame one and sensor frame two are made of insulating material.

[0014] Preferably, the end face shape of the adjustable magnetic flux density magnetic focusing structure one and the adjustable magnetic flux density magnetic focusing structure two is set as a curved surface that adapts to the irregular edge shape of the irregular edge metal plate.

[0015] Therefore, the present invention employs an adjustable magnetic flux density high-efficiency transverse magnetic inductor for heating irregularly shaped edges of metal plates with the above-described structure, achieving the following technical advantages compared to the prior art: 1. The sensor consists of two sensor units: Sensor Body 1 and Sensor Body 2. Each sensor body unit is a long straight copper tube with an adjustable magnetic flux density magnetizing structure with an irregularly shaped end face. Compared with traditional sensors made of single or multiple turns of copper tube, no winding is required.

[0016] 2. The end face shape of the adjustable magnetic flux density magnetic concentrating structure is set to a curved surface that matches the irregular edge shape of the metal plate to be heated, thereby improving heating efficiency.

[0017] 3. Two sensor units are connected in series via a water-cooled copper plate, and the distance between the sensor units is precisely adjustable to fit the workpiece being heated. The sensor and the IGBT induction heating power supply are connected by a water-cooled coaxial cable. The above connection method has low distributed inductance, low loss, and high efficiency.

[0018] 4. Based on the specific heating requirements, the total amount, installation distribution, and density of the adjustable magnetic flux density magnetic structure (magnetic conductor) can be adjusted to precisely control the distribution of heating energy and adapt to the process requirements.

[0027] Example like Figure 1-3 As shown, this embodiment provides an adjustable magnetic flux density high-efficiency transverse magnetic inductor for heating irregularly shaped edges of metal sheets. It includes an inductor body one and an inductor body two symmetrically arranged vertically, connected in series via a water-cooled copper plate 13. Inductor body one includes a straight copper tube 1 and an adjustable magnetic flux density focusing structure 3, which is mounted on the straight copper tube 1. Inductor body two includes a straight copper tube 2 and an adjustable magnetic flux density focusing structure 4, which is mounted on the straight copper tube 2.

[0028] A straight copper tube 1 has symmetrically arranged bent copper tubes 5 on both sides, and a straight copper tube 2 has symmetrically arranged bent copper tubes 2 on both sides. Straight copper tube 1 and bent copper tube 5 are integral structures, as are straight copper tube 2 and bent copper tube 2. All four tubes (straight copper tube 1, bent copper tube 5, straight copper tube 2, and bent copper tube 2) are made of oxygen-free copper. A shaped edge metal plate 12 is provided between straight copper tube 1 and straight copper tube 2. Cooling water inlets 10 are respectively provided on bent copper tubes 5 and 2. Bent copper tubes 5 and 2 are connected to the IGBT induction heating power supply 11 via a water-cooled coaxial cable.

[0029] The end face shapes of the adjustable magnetic flux density focusing structure 1 (3) and the adjustable magnetic flux density focusing structure 2 (4) are set to be curved surfaces adapted to the irregular edge shape of the irregular edge metal plate 12.

[0030] In this invention, the inductor comprises two inductor units: Inductor Body 1 and Inductor Body 2. Each inductor unit is a long, straight copper tube with an irregularly shaped magnetic conductor attached, eliminating the need for winding. The inductor is connected to the IGBT induction heating power supply 11 via a water-cooled coaxial cable. The two inductor units are connected in series via a water-cooled copper plate 13, and the distance between the two inductor units is precisely adjustable to ensure close contact with the heated workpiece. This connection method results in low distributed inductance, low loss, and high efficiency. The end face shape of the magnetic conductor is designed to conform to the irregular edge shape of the metal plate 12, improving heating efficiency. Based on specific heating requirements, the total number of magnetic conductors, their installation distribution, and their density within the inductor units are adjusted to precisely control the distribution of heating energy and adapt to process requirements.
