Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of induction heating, and in particular to an induction heating device based on temperature control. Background Art
[0002] Induction heating is based on Faraday's law of electromagnetic induction. When a conductive material (usually metal) is placed in a changing magnetic field, induced currents (eddy currents) are generated within the material. When these induced currents flow within the material, Joule heat (i.e., electric heating) is generated due to the material's resistance, causing the material to heat up. Induction heating systems typically include an induction coil powered by a high-frequency AC power supply (usually between a few kilohertz and several megahertz). The alternating magnetic field generated by the induction coil penetrates the metal workpiece, generating an induced current.
[0003] The existing induction heating of metal rods requires manual clamping and transportation by personnel, and cannot achieve fully automated transportation and heating. The staff must wait next to the induction heating equipment for one metal rod to finish heating, take out the heated metal rod, and then manually clamp and transport the next metal rod to the induction heating equipment for heating. This not only wastes manpower, but the induction heating equipment also generates a strong electromagnetic field. Long-term or frequent exposure to such an environment may have adverse effects on the human body, such as causing arrhythmia, dizziness, fatigue and other symptoms, posing a threat to the health of the operator.
[0004] Moreover, the diameters of metal rods are different, and their heat capacity and resistivity are different. Metal rods of different diameters and different materials require different heating temperatures. Existing induction heating equipment cannot adjust the appropriate heating temperature in real time according to the diameter and material of the metal rod. As a result, when metal rods of different diameters and materials are heated subsequently, the heating speed of the metal rod will be too slow, and the heating temperature may be too high or too low. Temperature changes will affect the thermal expansion of the metal rod. For some high-precision cylindrical parts, the dimensional accuracy requirements are very high. During the heating process, excessively high temperature will cause the metal rod to over-expand, and the size may exceed the tolerance range after cooling. If the temperature is too low, the thermal deformation temperature required for processing may not be reached.
[0005] Therefore, it is necessary to design an induction heating device that can control the heating temperature in real time according to the diameter and material and automatically convey the heating. Summary of the Invention

In the process of the first electric slide rail driving the first clamping assembly to slide, not only can the bar automatically enter the induction coil for heating, but also the support plate can be pushed to automatically return during the sliding process, effectively preventing the subsequent first clamping assembly from interfering with the support plate when sliding, and no additional drive is used during the horizontal placement and support plate return movements, thereby achieving energy-saving effects.
[0017] 2.

The infrared thermometer detects the temperature of the heated bar in real time. When the temperature of the metal bar reaches the heating temperature that matches its material, the heating power is automatically reduced to maintain temperature stability.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] For example 1, please refer to Figure 1-7 The present invention provides a technical solution: an induction heating device based on temperature control, comprising a workbench 3 and a control box arranged inside the workbench 3, a conveying mechanism 2 for conveying rods to the heating zone for heating is provided on the upper side of the workbench 3, a feeding mechanism 1 for storing rods and feeding the rods horizontally into the conveying mechanism 2 in sequence is provided on the upper side of the conveying mechanism 2, a heating mechanism 4 for induction heating the rods is provided on one side of the conveying mechanism 2, a picking mechanism 5 for taking out the heated rods is provided on one side of the picking mechanism 5, and a storage box 6 for storing the heated rods is provided on one side of the picking mechanism 5.
[0021] See also Figure 3 The feeding mechanism 1 includes four support columns 11 provided on the upper side of the workbench 3, and a storage box 12 is fixedly connected to the upper side of the support column 11, and a partition block 15 is fixedly connected to the interior of the storage box 12. The partition block 15 divides the interior of the storage box 12 into a storage chamber and a discharge chamber, and a number of avoidance grooves are evenly arranged inside the discharge chamber. An inclined plate 17 is fixedly connected to the interior of the storage chamber, and a first cylinder 14 is fixedly connected to the upper side of the partition block 15. A baffle plate 18 is slidably connected to the interior of the partition block 15. The output end of the first cylinder 14 passes through the partition block 15 and is fixedly connected to the baffle plate 18. A horizontal adjustment component 19 is provided on the lower side of the camera 13.
[0022] Supplementary explanations based on the above structure are as follows: the storage chamber is used to store rods, wherein the stored rods are of the same length, the inclined plate 17 is used to allow the rods to slide freely, and the extension and retraction of the output end of the first cylinder 14 is used to drive the baffle plate 18 to move up and down, thereby allowing the rods to slide into the inside of the discharge chamber or preventing the rods from sliding.
[0023] When unloading is required, the output end of the first cylinder 14 continues to retract until one of the bars slides into the inside of the discharge cavity, and the output end of the first cylinder 14 begins to extend until the bottom end of the baffle plate 18 is in contact with the inclined plate 17.
[0024] See also Figure 4 The horizontal adjustment assembly 19 includes two sliders 192 slidably connected to the inside of the storage box 12, and a first spring 191 is provided inside each avoidance groove, one end of the first spring 191 is fixedly connected to the avoidance groove and the other end is fixedly connected to the slider 192, and a support plate 193 is slidably connected to the inside of each slider 192, and a second spring 194 is fixedly connected to one side of the support plate 193 and the other end of the second spring 194 is fixedly connected to the slider 192, and a rubber pad 195 is fixedly connected to the upper side of the support plate 193, and one side of the support plate 193 and the rubber pad 195 are both inverted with an inclined surface, and the two inclined surfaces form a V shape.
[0025] Supplementary explanations based on the above structure are as follows: in the initial state, since the elastic force of the first spring 191 is greater than the sum of the gravity of the slider 192, the support plate 193, the second spring 194 and the rubber pad 195, the first spring 191 is not stretched to its original length, and the second spring 194 pushes the support plate 193 out through the elastic force, and the two support plates 193 fit together. The rubber pad 195 is used to prevent the rod from hitting the horizontal adjustment assembly 19 when it falls, causing the edge of the rod to be damaged.
[0026] See also Figure 5 and Figure 6 The conveying mechanism 2 includes a first electric slide rail 21 fixedly connected to the upper side of the workbench 3, and the sliding end of the first electric slide rail 21 is provided with a first clamping assembly 22. The first clamping assembly 22 includes a positioning frame 221 fixedly connected to the sliding end of the first electric slide rail 21, and an electric push rod 222 is provided inside the positioning frame 221. The two sides of the positioning frame 221 are respectively hinged with a first rotating plate 223 and a second rotating plate 224, one end of the electric push rod 222 is hinged to the first rotating plate 223 and the output end is hinged to the second rotating plate 224, the upper side of the positioning frame 221 is fixedly connected to a support block 226, one side of the support block 226 is fixedly connected to a trapezoidal block 225, and the lower side of the trapezoidal block 225 is fixedly connected to a clamping plate 227, and one side of the first rotating plate 223 and the second rotating plate 224 are respectively fixedly connected to two clamping blocks 228.
[0027] Supplementary explanation based on the above structure is as follows: the sliding of the sliding end of the first electric slide rail 21 is used to transport the rod material clamped by the first clamping assembly 22 to the inside of the induction coil 42, so that the induction coil 42 performs induction heating on the rod material, and the extension and retraction of the output end of the electric push rod 222 is used to control the first rotating plate 223 and the second rotating plate 224 to move closer to or farther away from each other, thereby controlling the clamping block 228 to clamp or release the rod material. The clamping block 228 is made of high-temperature resistant metal material, and the two sides of the trapezoidal block 225 fit together with the inclined surfaces of the support plate 193 and the rubber pad 195, and the support block 226 is used to support the rod material.
[0028] When one of the rods slides to the top of the rubber pad 195, since the weight of the rod is greater than the elastic force of the first spring 191, the first spring 191 is stretched, and the slider 192 slides down horizontally until the support plate 193 slides to the top of the card plate 229 and fits with the top of the card plate 229. At this time, the slider 192 no longer slides down, and the two sides of the trapezoidal block 225 fit with the inclined surfaces of the support plate 193 and the rubber pad 195. The upper plane of the trapezoidal block 225 is at the same level as the upper plane of the rubber pad 195 and the lowest point of the supporting surface above the support block 226. At this time, the output end of the electric push rod 222 begins to extend, driving the two clamping plates 227 to approach each other, so that the clamping block 228 clamps the bar. Since the slider 192 slides downward horizontally and is placed horizontally, the bar is clamped horizontally, which effectively prevents the two ends of the sliding bar from being unevenly placed, thereby causing the subsequent clamping block 228 to clamp crookedly, and then making the position of the bar in the induction coil 42 unstable during the transportation and heating process, resulting in uneven heating. Different parts of the bar will be heated to different degrees, thus affecting the final heating quality and performance.
[0029] When the bar is fully clamped, the sliding end of the first electric slide rail 21 drives the bar to extend into the interior of the induction coil 42 for heating. During the extension process, the two sides of the trapezoidal block 225 push the two support plates 193 respectively, so that the support plates 193 and the rubber pads 195 slide into the interior of the slider 192, thereby compressing the second spring 194. During the sliding process of the trapezoidal block 225, until the two sides of the trapezoidal block 225 no longer fit the inclined surfaces of the support plates 193 and the rubber pads 195, the support plates 193 completely slide into the interior of the slider 192, and the rubber pads 195 are no longer pressed by the bar. The distance between the two support plates 193 is greater than the diameter of the bar, and the elastic force of the first spring 191 is greater than the sum of the gravity of the slider 192, the support plate 193, the second spring 194 and the rubber pad 195. The first spring 191 begins to contract and restore its original length, and the slider 192 is indirectly driven to move upward to return, thereby preparing for the horizontal adjustment of the next bar.
[0030] The first spring 191 and the second spring 194 need to be replaced in time after long-term use to prevent the elastic force of the first spring 191 and the second spring 194 from decreasing and the slider 192 from being difficult to be fully driven back to its original position by the first spring 191.
[0031] See also Figure 7 The material-taking mechanism 5 includes a first support frame 51 provided on one side of the workbench 3, and a second electric slide rail 52 is fixedly connected to the upper side of the first support frame 51, and the sliding end of the second electric slide rail 52 is fixedly connected to the second support frame 55, and the interior of the second support frame 55 is fixedly connected to a guide slide column 53, and the outer side of the guide slide column 53 is slidably connected to a sliding frame 56, and the upper side of the second support frame 55 is fixedly connected to a third cylinder 57, and the output end of the third cylinder 57 passes through the second support frame 55 and is fixedly connected to the sliding frame 56, and the interior of the sliding frame 56 is fixedly connected to a second cylinder 54, and the output end of the second cylinder 54 is fixedly connected to a U-shaped plate 58, and the lower side of the U-shaped plate 58 is fixedly connected to a second clamping assembly 59.
[0032] Supplementary explanations based on the above structure are as follows: the second clamping assembly 59 is used to clamp one end of the bar material. The second clamping assembly 59 has the same structure as the first clamping assembly 22. The sliding of the sliding end of the second electric slide rail 52 is used to control the movement of the second clamping assembly 59, so that it is close to the upper end of the bar material that has been heated or drives the bar material to move above the storage box 6. The extension of the output end of the third cylinder 57 is used to drive the second clamping assembly 59 to move downward, thereby clamping the bar material that has been heated or sending the bar material that has been heated into the interior of the storage box 6. The extension of the output end of the second cylinder 54 is used to place the bar material that has been heated at different positions inside the storage box 6.
[0033] The induction coil 42 continues to heat the clamped rod until the rod is completely heated. The sliding end of the second electric slide 52 drives the second support frame 55 to slide, thereby driving the second clamping assembly 59 to slide above one end of the rod after heating. The output end of the third cylinder 57 extends to control the slide frame 56 to move horizontally downward along the guide column 53 until one end of the rod after heating enters the interior of the second clamping assembly 59. The second clamping assembly 59 clamps one end of the rod. The second electric slide 52 controls the second clamping assembly 59 to return to its position. The output end of the third cylinder 57 extends again, thereby driving the rod into the interior of the storage box 6, and then automatically sending the heated rod into the interior of the storage box 6.
[0034] By providing a feeding mechanism 1, a conveying mechanism 2 and a picking mechanism 5, the loading and unloading of the bar material can be automatically completed. This process does not require human operation, saving manpower. In the process of loading and clamping, it not only prevents the sliding height from being too high, causing the edge of the sliding bar to collide and cause damage, but the bar material is also driven by the slider 192 to slide downward and be placed horizontally, effectively preventing the two ends of the sliding bar from being placed unevenly, thereby causing the subsequent clamping block 228 to clamp crookedly, and then causing the position of the bar material in the induction coil 42 to be unstable during the conveying and heating process, resulting in uneven heating. In the process of the first electric slide rail 21 driving the first clamping assembly 22 to slide, not only can the bar material automatically enter the induction coil 42 for heating, but it can also push the support plate 193 to move and automatically return during the sliding process, effectively preventing the subsequent first clamping assembly 22 from interfering with the support plate 193 when sliding. No additional drive is used during the horizontal placement and support plate 193 return movement, achieving energy-saving effects.
[0035] In the second embodiment, the diameters of metal rods are different, and their heat capacity and resistivity are different. Metal rods of different diameters and different materials require different heating temperatures. The existing induction heating equipment cannot adjust the appropriate heating temperature in real time according to the diameter and material of the metal rod. As a result, when metal rods of different diameters and materials are subsequently heated, the heating speed of the metal rod is too slow, and the temperature may be too high or too low. The temperature change will affect the thermal expansion of the metal rod. For some high-precision cylindrical parts, the dimensional accuracy requirements are very high. During the heating process, excessively high temperature will cause the metal rod to over-expand, and the size may exceed the tolerance range after cooling. If the temperature is too low, the thermal deformation temperature required for processing may not be reached. Therefore, the following structure is designed to solve the above technical problems.
[0036] See also Figure 2 The heating mechanism 4 includes an induction heating cabinet 41 fixedly connected to the upper side of the workbench 3. An induction coil 42 is provided on one side of the induction heating cabinet 41. One end of the induction coil 42 is fixedly connected to the output end of the induction heating cabinet 41, and the other end of the induction coil 42 is fixedly connected to the input end of the induction heating cabinet 41. An infrared thermometer 43 is provided on the lower side of the induction coil 42, and the detection end of the infrared thermometer 43 faces upward.
[0037] Supplementary explanation based on the above structure is as follows: the induction heating cabinet 41 is used to provide alternating current. Its core is to convert the mains electricity into high-frequency, medium-frequency or low-frequency current suitable for induction heating and transmit it to the induction coil 42, and the heating time and heating power can be freely adjusted. When the metal workpiece is placed in the changing magnetic field generated by the induction coil 42, a closed induced current will be generated inside the metal. This current is called eddy current. In induction heating, the eddy current will flow inside the metal after it is generated. Due to the resistance characteristics of the metal, the eddy current interacts with the resistance to generate heat, thereby increasing the metal temperature.
[0038] The infrared thermometer 43 is used to detect the temperature of the heated bar in real time. The infrared thermometer 43 consists of an optical system, a photoelectric detector, a signal amplifier, signal processing, display output and other parts. When measuring temperature, the infrared energy emitted by the object to be measured is converged onto the infrared detector through the optical system. The detector converts the incident radiation energy into a corresponding electrical signal. The signal is then converted, amplified, processed and other processes, and finally converted into the temperature value of the measured target and displayed.
[0039] See also Figure 3 The lower inclined surface of the baffle plate 18 is fixedly connected with a touch button 16, and the upper inner wall of the discharge cavity is fixedly connected with a camera 13.
[0040] The supplementary explanation based on the above structure is as follows: the output end of the first cylinder 14 contracts and drives the baffle plate 18 to move upward until the rolling rod presses the touch button 16. At this time, the touch button 16 sends a signal to the control box, and the control box records the retraction length of the first cylinder 14, thereby obtaining the diameter of the sliding rod. The judgment module obtains a heating frequency that matches the diameter of the rod. A database and a judgment module are provided inside the control box. The database is provided with identification photos of metal rods of different colors and textures. When the rod slides into the discharge chamber, the camera 13 captures and images the rod. After the camera 13 takes an image of the surface of the rod, it converts the image into an electrical signal and sends it to the judgment module. The judgment module compares it with the identification photos of rods of different colors and textures in the internal database, pre-identifies the material of the rod, and divides the heating degree of the rod into deep heating, normal heating and shallow heating according to the obtained rod material.
[0041] When the color of the bar material photographed by camera 13 is silvery white, the texture is brushed, and the diameter of the bar material is less than or equal to 30 mm, the judgment module determines that the bar material is a small alloy steel bar material. Therefore, for small alloy steel bars, high-frequency current should be selected, so that the heating can be concentrated on the surface to achieve rapid temperature rise. The thermal conductivity of alloy steel is general, and the heat transfer speed is moderate. When heated, the temperature will rise steadily, so normal power is adjusted for normal heating.
[0042] When the color of the rod photographed by camera 13 is reddish-brown and has no fixed texture, and the diameter of the rod is less than or equal to 30 mm, the judgment module determines that the rod is a small copper rod. Since copper has good conductivity and low resistivity, high-frequency current is usually selected during induction heating, which can generate strong eddy currents on the surface of the copper and achieve rapid heating. Copper has high thermal conductivity and high electrical conductivity. When heated, a large number of eddy currents are quickly generated on the surface, heat is concentrated on the surface, and the temperature rises rapidly. Due to the high melting point, excessive power will cause overheating or oxidation of the surface, so low power is adjusted for shallow heating.
[0043] When the color of the rod photographed by camera 13 is raw gray, the texture is frosted, and the diameter of the rod is greater than 30 mm, the judgment module determines that this rod is a large titanium rod. Since the thermal conductivity of titanium is low, the heat propagates slowly inside the titanium, so low-frequency heating is required. During low-frequency heating, the eddy current penetration depth is greater, and the heat can be distributed more deeply into the interior of the titanium, so that the titanium is heated evenly as a whole. In addition, the thermal conductivity of titanium is low, and heat is difficult to propagate quickly during heating, resulting in a slow overall heating rate. Therefore, high power needs to be adjusted for deep heating.
[0044] The infrared thermometer 43 detects the temperature of the heated bar in real time. When the temperature of the metal bar reaches the heating temperature that matches the material, the heating power is reduced to an appropriate level based on this heating power to keep the temperature stable.
[0045] Through the shooting of the camera 13 and the sensing of the touch button 16, the material and diameter of the bar to be heated can be known in advance, so that the heating degree of the bar can be judged through the judgment module, and the heating frequency and heating power of the bar can be automatically adjusted, thereby improving the heating speed of each bar of different materials, achieving the effect of automatically regulating the heating frequency and power, and the infrared thermometer 43 detects the temperature of the heated bar in real time. When the temperature of the metal bar reaches the heating temperature matching its material, the heating power is automatically reduced to maintain temperature stability, effectively preventing the phenomenon that when metal rods of different diameters and different materials are heated, the heating frequency and power that match them cannot be automatically adjusted, resulting in the heating temperature of the metal rod being too high or too low.
