Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of induction heating, in particular to an induction heating device based on temperature control. BACKGROUND
[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, an induced current (eddy current) is generated inside the material. As the induced current flows inside the material, it generates Joule heat (i.e. electric heat) due to the electrical resistance of the material, thereby heating the material. An induction heating system usually includes an induction coil powered by a high-frequency alternating current source (usually between several kilohertz and several megahertz). The alternating magnetic field generated by the induction coil penetrates the metal workpiece, generating an induced current.
[0003] The existing metal rod induction heating needs to be manually clamped and transported by personnel, and cannot realize fully automatic transportation and heating. The worker needs to wait beside the induction heating device after one of the metal rods is heated, take out the metal rod that has been heated, and then manually clamp and transport the next metal rod into the induction heating device for heating. This not only wastes manpower, but also generates a strong electromagnetic field in the induction heating device. Long-term or frequent exposure to such an environment can cause adverse effects on the human body, such as arrhythmia, dizziness, and fatigue, posing a threat to the health of the operator.
[0004] In addition, the heat capacity and resistivity of metal rods of different diameters are different. Different diameters and different materials of metal rods require different heating temperatures. The existing induction heating device cannot adjust the appropriate heating temperature in real time according to the diameter and material of the metal rod, so that the heating speed of the subsequent metal rod of different diameters and materials will be too slow, and the heating temperature will be too high or too low. Temperature changes can affect the thermal expansion of the metal rod. For some high-precision cylindrical parts, the dimensional accuracy requirement is very high. During the heating process, excessive temperature can cause the metal rod to expand excessively, which may cause the size to exceed the tolerance range after cooling. Too low temperature may not be able to reach the required thermal deformation temperature.
[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 transport and heat. SUMMARY

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0034] Embodiment one, please refer to Figures 1-7 The present application 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, the upper side of the workbench 3 is provided with a conveying mechanism 2 for conveying the bar material to the heating area for heating, the upper side of the conveying mechanism 2 is provided with a feeding mechanism 1 for storing the bar material and feeding the bar material into the conveying mechanism 2 in sequence, one side of the conveying mechanism 2 is provided with a heating mechanism 4 for induction heating of the bar material, one side of the heating mechanism 4 is provided with a material taking mechanism 5 for taking out the bar material after heating, and one side of the material taking mechanism 5 is provided with a storage box 6 for storing the bar material after heating.
[0035] Please refer to Figure 3The feeding mechanism 1 comprises four supporting columns 11 arranged on the upper side of the workbench 3, the upper side of the supporting column 11 is fixedly connected with a storage box 12, the inside of the storage box 12 is fixedly connected with a partition block 15, the partition block 15 divides the inside of the storage box 12 into a storage cavity and a discharging cavity, a plurality of avoiding grooves are uniformly arranged in the inside of the discharging cavity, the inside of the storage cavity is fixedly connected with an inclined plate 17, the upper side of the partition block 15 is fixedly connected with a first air cylinder 14, the inside of the partition block 15 is slidingly connected with a blocking plate 18, the output end of the first air cylinder 14 penetrates through the partition block 15 and is fixedly connected with the blocking plate 18, and the lower side of the camera 13 is provided with a horizontal adjusting assembly 19.
[0036] The storage cavity is used for storing bars, the bars stored in the storage cavity are of the same length, the inclined plate 17 is used for enabling the bars to freely slide, the output end of the first air cylinder 14 is used for driving the blocking plate 18 to move up and down, so that the bars slide into the discharging cavity or are blocked from sliding.
[0037] When discharging is needed, the output end of the first air cylinder 14 continuously retracts until one of the bars slides into the discharging cavity, and then the output end of the first air cylinder 14 starts to extend until the bottom end of the blocking plate 18 is attached to the inclined plate 17.
[0038] Please refer to Figure 4 The horizontal adjusting assembly 19 comprises two sliding blocks 192 slidingly connected in the inside of the storage box 12, the inside of each avoiding groove is provided with a first spring 191, one end of the first spring 191 is fixedly connected with the avoiding groove and the other end is fixedly connected with the sliding block 192, the inside of each sliding block 192 is slidingly connected with a supporting plate 193, one side of the supporting plate 193 is fixedly connected with a second spring 194 and the other end of the second spring 194 is fixedly connected with the sliding block 192, the upper side of the supporting plate 193 is fixedly connected with a rubber pad 195, and one side of the supporting plate 193 and the rubber pad 195 is provided with an inclined surface, and the two inclined surfaces form a V shape.
[0039] Based on the supplementary explanation of the above structure, in the initial state, because the elastic force of the first spring 191 is greater than the total gravity of the sliding block 192, the supporting plate 193, the second spring 194 and the rubber pad 195, the first spring 191 is not stretched and is in the original length, the second spring 194 pushes the supporting plate 193 out through the elastic force, the two supporting plates 193 are attached to each other, and the rubber pad 195 is used for preventing the bars from impacting the horizontal adjusting assembly 19 when falling, so that the edges of the bars are not damaged.
[0040] Please refer to Figure 5 and Figure 6The conveying mechanism 2 comprises a first electric sliding rail 21 fixedly connected to the upper side of the workbench 3, a first clamping assembly 22 is arranged at the sliding end of the first electric sliding rail 21, the first clamping assembly 22 comprises a positioning frame 221 fixedly connected to the sliding end of the first electric sliding rail 21, an electric push rod 222 is arranged in the positioning frame 221, the two sides of the positioning frame 221 are respectively hingedly connected with a first rotating plate 223 and a second rotating plate 224, one end of the electric push rod 222 is hingedly connected with the first rotating plate 223 and the output end is hingedly connected with the second rotating plate 224, a supporting block 226 is fixedly connected to the upper side of the positioning frame 221, a trapezoidal block 225 is fixedly connected to one side of the supporting block 226, a clamping plate 229 is fixedly connected to the lower side of the trapezoidal block 225, the first rotating plate 223 and the second rotating plate 224 are both fixedly connected with a clamping plate 227 on one side, and two clamping blocks 228 are respectively fixedly connected to one side of the clamping plate 227.
[0041] The first electric sliding rail 21 is used for conveying the bar material clamped by the first clamping assembly 22 into the induction coil 42, so that the induction coil 42 is used for inductively heating the bar material, the output end of the electric push rod 222 is used for controlling the first rotating plate 223 and the second rotating plate 224 to move close to or away from each other, so as to control the clamping blocks 228 to clamp or release the bar material, the clamping blocks 228 are made of high-temperature-resistant metal material, the two sides of the trapezoidal block 225 are matched with the inclined surfaces of the supporting plate 193 and the rubber pad 195, and the supporting block 226 is used for supporting the bar material.
[0042] When one of the bar materials slides to the upper side of the rubber pad 195, the first spring 191 is stretched due to the weight of the bar material being greater than the elastic force of the first spring 191, the sliding block 192 slides horizontally downward until the supporting plate 193 slides to the upper side of the clamping plate 229 and is attached to the upper side of the clamping plate 229, at this time, the sliding block 192 no longer slides downward, the two sides of the trapezoidal block 225 are matched with the inclined surfaces of the supporting plate 193 and the rubber pad 195, the upper plane of the trapezoidal block 225 and the upper plane of the rubber pad 195 and the lowest point of the upper supporting surface of the supporting block 226 are in the same horizontal plane, at this time, the output end of the electric push rod 222 starts to extend, and the two clamping plates 227 are moved close to each other, so that the clamping blocks 228 clamp the bar material, since the sliding block 192 slides horizontally downward and is horizontally placed, the bar material is clamped horizontally, which effectively prevents the two ends of the bar material from being placed unevenly after sliding down, so that the subsequent clamping blocks 228 are clamped skewed, and then the position of the bar material in the induction coil 42 is unstable during the conveying and heating process, which leads to uneven heating, different parts of the bar material are heated to different degrees, and finally the heating quality and performance are affected.
[0043] When the bar is completely clamped, the sliding end of the first electric sliding rail 21 drives the bar to extend into the inside of the induction coil 42 for heating. In the process of extending, the two sides of the trapezoidal block 225 push the two support plates 193 respectively, so that the support plates 193 and the rubber pad 195 slide into the inside of the sliding block 192, and then the second spring 194 is compressed. In the process of sliding of the trapezoidal block 225, until the two sides of the trapezoidal block 225 no longer fit with the inclined surfaces of the support plates 193 and the rubber pad 195, at this time the support plates 193 completely slide into the inside of the sliding block 192, the rubber pad 195 is no longer pressed by the bar, and the distance between the two support plates 193 away from each other is greater than the diameter of the bar. The elastic force of the first spring 191 is greater than the total weight of the sliding block 192, the support plates 193, the second spring 194 and the rubber pad 195, the first spring 191 starts to contract and restores the original length, and the sliding block 192 is indirectly driven to move upward for resetting, so as to prepare for the horizontal adjustment of the next bar.
[0044] The first spring 191 and the second spring 194 need to be replaced in time after long-term use, so as to prevent the elastic force of the first spring 191 and the second spring 194 from decreasing and the sliding block 192 from being difficult to be completely reset by the first spring 191.
[0045] Please refer to Figure 7 , the taking mechanism 5 comprises a first support frame 51 arranged on one side of the workbench 3, the upper side of the first support frame 51 is fixedly connected with a second electric sliding rail 52, the sliding end of the second electric sliding rail 52 is fixedly connected with a second support frame 55, the inside of the second support frame 55 is fixedly connected with a guide sliding column 53, the outer side of the guide sliding column 53 is slidably connected with a sliding frame 56, the upper side of the second support frame 55 is fixedly connected with a third air cylinder 57, the output end of the third air cylinder 57 penetrates through the second support frame 55 and is fixedly connected with the sliding frame 56, the inside of the sliding frame 56 is fixedly connected with a second air cylinder 54, the output end of the second air cylinder 54 is fixedly connected with a U-shaped plate 58, and the lower side of the U-shaped plate 58 is fixedly connected with a second clamping assembly 59.
[0046] The second clamping assembly 59 is used for clamping one end of the bar, the structure of the second clamping assembly 59 is the same as that of the first clamping assembly 22, the sliding of the sliding end of the second electric sliding rail 52 is used for controlling the second clamping assembly 59 to move, so as to make it close to the upper side of the end of the bar after heating or drive the bar to move above the storage box 6, the extension of the output end of the third air cylinder 57 is used for driving the second clamping assembly 59 to move downward, so as to clamp the bar after heating or send the bar after heating into the inside of the storage box 6, and the extension and contraction of the output end of the second air cylinder 54 is used for placing the bar after heating at different positions in the inside of the storage box 6.
[0047] The induction coil 42 continues to heat the clamped bar until the bar is completely heated, the second electric sliding rail 52 drives the second support frame 55 to slide, thereby driving the second clamping assembly 59 to slide above one end of the bar that has finished heating, the third cylinder 57 outputs to control the sliding frame 56 to move horizontally downward along the guide sliding column 53 until one end of the bar that has finished heating enters the second clamping assembly 59, and the second clamping assembly 59 clamps one end of the bar, and the second electric sliding rail 52 controls the second clamping assembly 59 to return, and the third cylinder 57 outputs again, thereby driving the bar to enter the inside of the storage box 6, and then the bar that has finished heating is automatically fed into the inside of the storage box 6.
[0048] By setting the feeding mechanism 1, the conveying mechanism 2 and the taking mechanism 5, the feeding and discharging of the bar can be automatically completed, and the process does not need to be operated by personnel, thereby saving manpower, and in the process of clamping feeding, the height of the bar that slides down is prevented from being too high, the edge of the bar that slides down is prevented from being impacted to cause damage, the bar is prevented from being placed unevenly at both ends, thereby preventing the subsequent clamping block 228 from being clamped obliquely, and the position of the bar in the induction coil 42 is prevented from being unstable in the process of conveying and heating, thereby preventing the phenomenon of uneven heating from occurring, and in the process of sliding the first clamping assembly 22 driven by the first electric sliding rail 21, the bar can be automatically fed into the inside of the induction coil 42 for heating, and the support plate 193 can be automatically returned by being driven to move, thereby preventing the subsequent first clamping assembly 22 from interfering with the support plate 193, and in the process of horizontal placement and return of the support plate 193, no additional driving is used, thereby achieving the effect of energy saving.
[0049] In the embodiment two, the diameters of the metal bars are different, the heat capacity and resistivity are different, the metal bars with different diameters and different materials need 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 bar, thereby causing the heating speed of the metal bar with different diameters and different materials to be too slow, and the temperature may be too high or too low, the temperature change affects the thermal expansion of the metal bar, for some high-precision cylindrical parts, the size precision requirement is high, and in the heating process, the temperature is too high, which may cause the metal bar to excessively expand, and after cooling, the size may exceed the tolerance range, and the temperature is too low, which may not reach the required thermal deformation temperature, and therefore, the following structure is designed to solve the above technical problems.
[0050] Please refer to Figure 2The heating mechanism 4 comprises an induction heating cabinet 41 fixedly connected to the upper side of the workbench 3, one side of the induction heating cabinet 41 is provided with an induction coil 42, one end of the induction coil 42 is fixedly connected with the output end of the induction heating cabinet 41, the other end of the induction coil 42 is fixedly connected with the input end of the induction heating cabinet 41, and the lower side of the induction coil 42 is provided with an infrared temperature detector 43 with the detection end of the infrared temperature detector 43 upward.
[0051] The induction heating cabinet 41 is used to provide alternating current, the core of which is to convert the mains into high-frequency, medium-frequency or low-frequency current suitable for induction heating and deliver 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 induction current will be generated in the metal, this current is called eddy current, in induction heating, the eddy current will flow in the metal after being generated, due to the resistance characteristics of the metal, the eddy current interacts with the resistance to generate heat, thereby increasing the temperature of the metal.
[0052] The infrared temperature detector 43 is used to detect the temperature of the heated bar in real time, the infrared temperature detector 43 is composed of an optical system, a photoelectric detector, a signal amplifier, a signal processing and display output, etc., when measuring the temperature, the infrared energy emitted by the measured object is converged on the infrared detector through the optical system, the detector converts the incident radiation energy into corresponding electrical signals, the signals are converted, amplified, processed, etc., and finally the temperature value of the measured target is converted and displayed.
[0053] Please refer to Figure 3 The lower inclined surface of the material blocking plate 18 is fixedly connected with the touch button 16, and the upper side of the inner wall of the discharging cavity is fixedly connected with the camera 13.
[0054] Based on the above structure, the output end of the first air cylinder 14 is retracted to drive the material blocking plate 18 to move upward until the rolling down bar presses the touch button 16, at this time the touch button 16 emits a signal to the control box, the control box records the length of the retraction of the first air cylinder 14, thereby obtaining the diameter of the sliding bar, the judgment module obtains the heating frequency matched with the diameter of the bar, the control box is internally provided with a database and a judgment module, the database is internally provided with identification photos of metal bars of different colors and textures, when the bar slides into the discharging cavity, the camera 13 takes an image of the bar, after the camera 13 takes an image of the surface of the bar, the image is converted into an electrical signal and sent to the judgment module, the judgment module compares it with the identification photos of bars of different colors and textures in the internal database, the material of the bar is identified in advance, and according to the obtained material of the bar, the heating degree of the bar is divided into deep heating, normal heating and shallow heating.
[0055] When the color of the bar material photographed by the camera 13 is silver-white, the texture is wire drawing texture, and the diameter of the bar material is less than or equal to 30 mm, the judgment module judges that the bar material is a small-sized alloy steel bar material, and thus high-frequency current needs to be selected for the small-sized alloy steel bar material, so that the heating is concentrated on the surface, rapid heating is achieved, the thermal conductivity of the alloy steel is general, the heat propagation speed is moderate, the temperature will steadily rise during heating, and thus the normal power is adjusted for normal heating.
[0056] When the color of the bar material photographed by the camera 13 is red-brown and has no fixed texture, and the diameter of the bar material is less than or equal to 30 mm, the judgment module judges that the bar material is a small-sized copper bar material, since the conductivity of copper is very good and the resistivity is low, high-frequency current is usually selected during induction heating, so that strong eddy current can be generated on the surface of the copper to achieve rapid heating, and the copper has high thermal conductivity and high electrical conductivity, a large amount of eddy current is rapidly generated on the surface during heating, heat is concentrated on the surface, the temperature rapidly rises, and since the melting point is high, too high power will cause the surface to overheat or oxidize, and thus low power is adjusted for shallow heating.
[0057] When the color of the bar material photographed by the camera 13 is gray, the texture is frosted, and the diameter of the bar material is greater than 30 mm, the judgment module judges that the bar material is a large-sized titanium bar material, since the thermal conductivity of titanium is low and the heat propagates slowly inside the titanium, low-frequency heating is required, the depth of penetration of eddy current is large during low-frequency heating, and heat can be more deeply distributed to the inside of the titanium, so that the titanium is uniformly heated as a whole, and since the thermal conductivity of titanium is low, heat is difficult to rapidly propagate during heating, which causes the overall temperature to rise slowly, and thus high power is adjusted for deep heating.
[0058] The infrared temperature detector 43 detects the temperature of the heated bar material in real time, when the temperature of the metal bar material reaches the heating temperature matched with the material, the heating power is reduced to an appropriate level on the basis of the heating power to maintain the stability of the temperature.
[0059] Through the shooting of the camera 13 and the sensing of the touch button 16, the material and diameter of the bar material to be heated are known in advance, so that the judgment module judges the heating degree of the bar material, and then automatically adjusts the heating frequency and heating power of the bar material, which improves the heating speed of each different material bar, achieves the effect of automatically adjusting the heating frequency and power, and the infrared temperature detector 43 detects the temperature of the heated bar material in real time, when the temperature of the metal bar material reaches the heating temperature matched with the material, the heating power is automatically reduced to maintain the stability of the temperature, which effectively prevents the different diameters and different materials of the metal bar from being unable to automatically adjust the heating frequency and power matched with them during heating, so that the heating temperature of the metal bar is too high or too low.
