Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic induction heating, and in particular to a matrix type electromagnetic induction heating device. Background Art

[0002] An electromagnetic induction heating device is a device that uses the principle of electromagnetic induction to achieve heating. It generates eddy currents inside a conductor through high-frequency current, thereby heating the conductor. Since the eddy currents are mainly concentrated near the surface of the conductor, a fast and uniform heating effect can be achieved. Compared with traditional heating methods, induction heaters can save energy and improve production efficiency. Induction heaters are widely used in the industrial field. However, when a matrix electromagnetic induction heating device is used, the number and position of the conductors arranged in a matrix are usually relatively fixed, and it is difficult to quickly adjust the position and number of the conductors according to the iron workpieces of different shapes and sizes. As a result, the matrix electromagnetic induction heating device cannot quickly heat the iron workpieces of different shapes and sizes as needed, which in turn affects the scope of use of the matrix electromagnetic induction heating device to a certain extent. At the same time, it also reduces the heating effect of the matrix electromagnetic induction heating device on iron workpieces of different specifications, resulting in certain deficiencies in the use of the matrix electromagnetic induction heating device.

The matrix splicing unit 21 is used to splice and fix the position of the fixed frame 12. The matrix splicing unit 21 includes a fixed plate 2101. The bottom surface of the fixed plate 2101 is fixedly connected to the upper surface of the base 11.

The distribution of 2104 is that one splicing seat 2104 is fixed on each of the two splicing plates 2102, two splicing seats 2104 are fixed on the fixed plate 2101, and four splicing seats 2104 are fixed on the folding plate 2103, each splicing seat 2104 is slidably connected to the inside of a connecting rod 2105, and the outer surface of each connecting rod 2105 is slidably connected to two clamping blocks 2106, the upper surface of each clamping block 2106 is an inclined surface, and one side of each clamping block 2106 is fixedly connected to two return springs 2107, and the other end of each return spring 2107 is fixedly connected to the inner wall of the splicing seat 2104, and the interior of each clamping block 2106 is slidably connected to a limiting ring 2108, and the limiting ring 2108 is fixedly sleeved on the connecting rod. On the connecting rod 2105, the bottom surface of each fixing frame 12 is fixedly connected with a conductive seat 2109, each conductive seat 2109 is electrically connected to the electric heating conductor 13 through a wire, each conductive seat 2109 is clamped in the corresponding splicing seat 2104, the bottom surface of each conductive seat 2109 is fixedly connected with a clamping seat 2110, each clamping seat 2110 is clamped in the corresponding splicing seat 2104, and the side of each clamping seat 2110 is provided with a clamping groove 2118, wherein four clamping blocks 2106 are clamped in the corresponding clamping groove 2118, and the interior of each splicing seat 2104 is slidably connected with a push plate 2111, and the bottom surface of each push plate 2111 is fixedly connected with two compression springs 2112, each compression spring The bottom ends of 2112 are all fixedly connected to the inner bottom of the splicing seat 2104, wherein the upper surfaces of the four push plates 2111 are in contact with the bottom surface of the clamping seat 2110. By setting the matrix splicing unit 21, the electric heating conductor 13 and the fixing frame 12 can be quickly spliced ​​or disassembled as needed, and the matrix splicing area of ​​the electric heating conductor 13 and the fixing frame 12 can be quickly increased, so that the matrix electromagnetic induction heating device can quickly adjust the position and number of the electric heating conductor 13 according to iron workpieces of different shapes and sizes, which greatly increases the heating adaptability of the matrix electromagnetic induction heating device to iron workpieces, improves the use range of the matrix electromagnetic induction heating device, and increases the heating effect of the matrix electromagnetic induction heating device on iron workpieces of different specifications; The side surfaces of the two splicing plates 2102 that are away from each other and the two ends of the folding plate 2103 in the length direction are fixedly connected with insulating plates 2113. The insulating plates 2113 can seal the edge positions of the splicing plates 2102 and the folding plates 2103 to prevent the splicing seat 2104 at the edge from being accidentally touched and causing injury by electric current, thereby increasing the safety of the splicing plates 2102 and the folding plates 2103. One end of each connecting rod 2105 is fixedly connected to a baffle 2114, and one side of each baffle 2114 close to the clamping block 2106 is fixedly connected to two return springs 2115, and the other end of each return spring 2115 is fixedly connected to the splicing seat 2104. The baffle 2114 can limit the position of the connecting rod 2105 inside the splicing seat 2104, and at the same time, it is convenient for the user to manually pull the connecting rod 2105. The return spring 2115 can increase the elastic force of the connecting rod 2105 when returning, so that the connecting rod 2105 can return more accurately and quickly; Several positioning holes 2116 are provided on the upper surface of the fixed plate 2101, the upper surfaces of the two splicing plates 2102 and the upper surface of the folding plate 2103. Four positioning columns 2117 are fixedly connected to the bottom surface of each fixing frame 12. Each positioning column 2117 is snapped into the inside of the positioning hole 2116. By using the positioning holes 2116 in conjunction with the positioning columns 2117, the accuracy of splicing the fixing frame 12 and the splicing seat 2104 can be increased, making the splicing of the fixing frame 12 more accurate and reliable.

[0020] The specific implementation method of this embodiment is as follows: the user starts the electric heating conductor 13 through an external control switch and power supply, and then places the iron workpiece to be heated on the carrier 14, and uses the electromagnetic eddy current generated by the electric heating conductor 13 to increase the atomic movement in the iron workpiece, thereby realizing the heating of the iron workpiece. When it is necessary to increase the matrix area of ​​the electromagnetic induction heating device to heat iron workpieces of different specifications, it is only necessary to insert the clamping seat 2110 into the interior of the splicing seat 2104 with the assistance of the positioning column 2117 and the positioning hole 2116 of the fixing frame 12. When the clamping seat 2110 enters the interior of the splicing seat 2104, the downward pressure of the clamping seat 2110 cooperates with the inclined surface of the clamping block 2106, which will push the clamping block 2106 on the connecting rod 2105. The clamping seat 2110 is pressed against the push plate 2111 to push the spring 2112 upwards and the spring 2113 is pressed against the push plate 2111 to push the spring 2112 upwards. The clamping of 2106 forms a vertical torque, which further increases the stability of the clamping seat 2110 after it is clamped into the splicing seat 2104. When heating a smaller iron workpiece, in order to reduce power consumption, it is necessary to remove the redundant fixing frame 12 and the electric heating conductor 13. At this time, it is only necessary to manually pull the baffle plate 2114, so that the connecting rod 2105 can pull the clamping block 2106 to one side with the cooperation of the limit ring 2108, so that the clamping block 2106 is disengaged from the clamping groove 2118. At this time, under the push of the compression spring 2112 and the push plate 2111, the clamping seat 2110 and the fixing frame 12 will be pushed upward, and the fixing frame 12 and the electric heating conductor 13 can be quickly removed. In addition, since the splicing plate 2102 and the folding plate 2103 are connected to the fixing plate 2101 They are all movable hinges, and can be further folded to reduce the volume of the matrix electromagnetic induction heating device when heating small iron workpieces, so that it will not occupy too much working space when heating smaller iron workpieces, so that the electric heating conductor 13 and the fixing frame 12 can be quickly spliced ​​or disassembled according to needs, and the matrix splicing area of ​​the electric heating conductor 13 and the fixing frame 12 can be quickly increased, so that the matrix electromagnetic induction heating device can quickly adjust the position and number of the electric heating conductors 13 according to iron workpieces of different shapes and sizes, which greatly increases the heating adaptability of the matrix electromagnetic induction heating device to iron workpieces, improves the application range of the matrix electromagnetic induction heating device, and increases the heating effect of the matrix electromagnetic induction heating device on iron workpieces of different specifications.

[0021] Example 2: Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 The present invention provides a technical solution: a matrix electromagnetic induction heating device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The assembly mechanism 2 also includes a splicing power connection unit 22, which is arranged on one side of the matrix splicing unit 21. The splicing power connection unit 22 is used to ensure that the electric heating conductor 13 is smoothly connected to the power.

[0022] As a further limitation of the assembly mechanism 2 of the present invention, the splicing electrical unit 22 includes two conductive frames 2201, the two conductive frames 2201 are fixedly connected to the fixed plate 2101, the interior of the two conductive frames 2201 is clamped with two first conductive blocks 2202, the side of each group of first conductive blocks 2202 is electrically connected to the plug 2203 through a wire, the number of each group of first conductive blocks 2202 is two, the outer surface of each conductive seat 2109 is fixedly connected to four connecting frames 2204, each connecting frame 2204 is clamped to the inside of the corresponding splicing seat 2104, the upper surface of each connecting frame 2204 is fixedly connected to the bottom surface of the fixed frame 12, the interior of each connecting frame 2204 is slidably connected to a sliding frame 2205, and the side of each sliding frame 2205 close to the conductive seat 2109 is fixedly connected A fastening spring 2206, the other end of each fastening spring 2206 is fixedly connected to the inner side wall of the connecting frame 2204, two second conductive blocks 2207 are clamped inside each sliding frame 2205, the other end of each second conductive block 2207 penetrates the sliding frame 2205 and is fixedly connected to a connecting wire 2208, each connecting wire 2208 is electrically connected to the conductive seat 2109 through a wire, and by providing a splicing power connection unit 22, it is possible to ensure that the electric heating conductor 13 and the fixing frame 12 can be quickly spliced, while there is no need to add power cords separately for multiple electric heating conductors 13, so that the electric heating conductor 13 and the fixing frame 12 can be quickly put into use after splicing, further increasing the convenience of use of the matrix electromagnetic induction heating device after splicing, making the matrix splicing of the matrix electromagnetic induction heating device simpler and more convenient; Two telescopic rods 2209 are fixedly connected to the inner wall of each connecting frame 2204, and the telescopic end of each telescopic rod 2209 is fixedly connected to a side of the sliding frame 2205 close to the conductive seat 2109. The telescopic rods 2209 can limit the sliding distance of the sliding frame 2205 inside the connecting frame 2204 without affecting the smooth sliding of the sliding frame 2205 inside the connecting frame 2204, thereby preventing the sliding frame 2205 from loosening from the connecting frame 2204.

[0023] The specific implementation method of this embodiment is as follows: first, the required electric heating conductor 13 is inserted into the splicing seat 2104 through the card seat 2110, and then connected to the plug 2203 through the external control switch and power supply. When the card seat 2110 is inserted into the splicing seat 2104, the conductive seat 2109 will also be inserted into the splicing seat 2104, and then the connecting frame 2204 will also be inserted into the splicing seat 2104. In the process of the connecting frame 2204 being inserted into the splicing seat 2104, the sliding frame 2205 will first connect with the conductive frame 2201. At this time, the downward pressure will force the sliding frame 2205 to retract into the connecting frame 2204, and at the same time force the fastening spring 2206 to contract, until the connecting frame 2204 is completely inserted into the splicing seat 2104, the sliding frame 2205 will be parallel to the conductive frame 2201, and the second conductive block 2207 will contact the first conductive block 2202, and then after turning on the external control switch, the current can be transmitted to the second conductive block 2207 through the plug 2203 and the first conductive block 2202. The wiring 2208 is electrically connected to the conductive seat 2109, and the conductive seat 2109 is electrically connected to the electric heating conductor 13, so that the electric heating conductor 13 can be smoothly connected to the power supply. At the same time, because the splicing seats 2104 are arranged adjacent to each other, and the connecting frames 2204 are also distributed in the four directions of the conductive seat 2109, when the plurality of fixing frames 12 are inserted into the splicing seats 2104 through the clamping seats 2110, whether they are arranged vertically or horizontally, the second conductive blocks 2204 in the adjacent connecting frames 2204 will be connected to each other. 207 are in contact with each other, so that the fixed frame 12 and the electric heating conductor 13 arranged in a matrix-like splicing arrangement can be connected in series. The multiple electric heating conductors 13 after splicing can be powered at the same time through only two conductive frames 2201, and there is no need to add power lines separately for the multiple electric heating conductors 13, so that the electric heating conductors 13 and the fixed frame 12 can be quickly put into use after splicing, further increasing the convenience of use of the matrix electromagnetic induction heating device after splicing, making the use of the matrix electromagnetic induction heating device during matrix splicing simpler and more convenient.

[0024] Example 3: Please refer to Figure 8 , Fig. 9 and Fig.10 The present invention provides a technical solution: a matrix electromagnetic induction heating device.

The auxiliary block 313 slides inside the auxiliary groove 312, which can increase the coordination stability between the support frame 309 and the base 11, and ensure the supporting effect of the support frame 309 on the folding plate 2103.

[0026] The specific implementation of this embodiment is as follows: When the splicing plate 2102 is unfolded upward, the movable seat 308 cooperates with the guide rod 307 to pull the moving frame 303 to slide inside the guide rail 301. During the sliding process of the moving frame 303, the card plate 304 will be driven to slide upward. Since the back side of the card plate 304 is set as an arc surface, the card plate 304 will not be engaged with the tooth plate 302 when sliding upward. When the splicing plate 2102 is fully unfolded, the thrust provided by the push spring 305 cooperates with the moving frame 303, which will force the bottom surface of the card plate 304 to be engaged with the tooth plate 302, so that the moving frame 303 cannot move downward, thereby completing the fixation of the unfolded splicing plate 2102.

[0027] When the splicing plate 2102 needs to be folded and stored, it is only necessary to use the clamping frame 311 to manually pull the pull rod 306 to force the push spring 305 to contract, thereby driving the clamping plate 304 to disengage from the tooth plate 302, thereby releasing the limit on the splicing plate 2102 and allowing it to be folded smoothly. When the folding plate 2103 is unfolded to be parallel to the fixed plate 2101, it is only necessary to manually pull out the support frame 309 to the right, and the support frame 309 can slide to the right with the assistance of the auxiliary block 313 and the auxiliary groove 312, and the upper surface of the support frame 309 contacts the bottom surface of the folding plate 2103, and then the telescopic frame 310 is pulled out from the inside of the support frame 309, which can increase the support frame 309 to The supporting area of ​​the folding plate 2103 can limit and support the position of the folding plate 2103 at this time, and then through the supporting mechanism 3, the unfolded splicing plate 2102 and folding plate 2103 can be supported, so that the unfolded splicing plate 2102 and folding plate 2103 are not easy to loosen, and the stability of the splicing plate 2102 and folding plate 2103 when used after being unfolded is improved, and at the same time, the carrying capacity of the splicing plate 2102 and folding plate 2103 is increased, so that after heavier iron workpieces are placed on the splicing plate 2102 and folding plate 2103, it is not easy to cause the splicing plate 2102 and folding plate 2103 to deviate and affect the heating effect and the normal power supply of the electric heating conductor 13.
