Description

Technical Field

[0001] This application belongs to the field of medium-frequency heating furnace technology, and particularly relates to a medium-frequency heating furnace. Background Technology

[0002] Before forging, the round steel bars need to be heated in an induction heating furnace. The high-temperature bars output from the induction heating furnace are transported by a chain conveyor, and a discharge device for receiving the material is provided at the end of the chain conveyor.

[0003] Patent CN219368391 U discloses a discharge device for a medium-frequency heating furnace. The receiving mechanism includes an electric rotating indexing plate, which comprises a receiving turntable and a power unit mounted on a lifting plate. The receiving turntable has multiple inclined slots distributed circumferentially, and round steel bars sliding down the V-shaped receiving groove are obliquely inserted into the inclined slots. An adjusting plate is provided below the lifting plate, and the lifting plate and the adjusting plate are connected by a height adjustment mechanism. The adjusting plate is connected to the base by a position adjustment mechanism.

[0004] The aforementioned patent uses a height adjustment mechanism, which mainly relies on the rotation of the adjusting nut for adjustment. Although it can achieve the height adjustment effect, it requires manual adjustment, which leads to low adjustment efficiency and low adjustment accuracy, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a medium-frequency heating furnace that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a medium-frequency induction heating furnace, including a furnace body, a conveyor table for conveying bar stock, a receiving device for receiving the stock, and a moving device for adjusting the horizontal position of the receiving device, and further including:

[0007] A lifting device is installed at the bottom of the receiving device and is used to adjust the height of the receiving device.

[0008] The conveyor platform is equipped with a V-shaped receiving groove that extends above the receiving device, through which the bar stock slides onto the receiving device.

[0009] The aforementioned medium-frequency induction heating furnace heats the bar stock, while a conveyor platform transports the bar stock. A V-shaped receiving trough extending above a receiving device is provided on the conveyor platform, allowing the bar stock to slide smoothly onto the receiving device. The receiving device then receives the bar stock sliding off the conveyor platform. A movable device adjusts the horizontal position of the receiving device to meet different production needs. A lifting device located at the bottom of the receiving device automatically adjusts its height, replacing the traditional manual adjustment nut method and significantly improving adjustment efficiency and accuracy.

[0010] By employing the aforementioned lifting device, the medium-frequency heating furnace of this application achieves automatic adjustment of the material receiving device height, which not only simplifies the operation process and reduces labor intensity, but also significantly improves adjustment efficiency and accuracy. Simultaneously, the introduction of the lifting device enhances the overall automation level of the medium-frequency heating furnace, contributing to a more efficient and stable production process.

[0011] Furthermore, the lifting device includes:

[0012] The lifting plate and the material receiving device are located on the top of the lifting plate;

[0013] The base plate is located below the lifting plate, and the moving device is located at the bottom of the base plate;

[0014] The drive mechanism, mounted on the base plate and connected to the lifting plate, is used to drive the lifting plate to move up and down;

[0015] There is a gap between the base plate and the moving device, and the bottom of the drive mechanism is located within the gap.

[0016] The lifting device, connected to the lifting plate via a drive mechanism, enables automatic adjustment of the receiving device's height, eliminating the need for traditional manual adjustment and significantly improving efficiency. This allows operators to adjust the receiving device's height more quickly and accurately to meet varying production needs. The gap between the base plate and the moving device provides sufficient space for the bottom of the drive mechanism, preventing interference during movement and ensuring smooth operation, further enhancing equipment stability and reliability. Furthermore, the introduction of the lifting device significantly improves the automation level of the medium-frequency induction heating furnace. By automatically adjusting the receiving device's height, it enables coordinated operation with other equipment such as the conveyor platform and the furnace body, further improving production efficiency and quality.

[0017] Furthermore: the drive mechanism includes:

[0018] The connecting assembly consists of a first link and a second link that are hinged to each other. One end of the first link is hinged to the base plate, and the other end is movably mounted on the lifting plate. One end of the second link is hinged to the lifting plate, and the other end is movably mounted on the base plate.

[0019] The drive assembly includes a driver disposed within the gap, a lifting rod connected to the output shaft of the driver, both ends of the lifting rod being hinged to the first link, and the driver being able to slide on the base plate;

[0020] The connecting components are provided in two sets, and a support rod is provided between the two sets of connecting components. The support rod is located at the hinge of the first connecting rod and the second connecting rod.

[0021] The connecting assembly in the drive mechanism consists of a first link and a second link hinged together, making the height adjustment of the lifting plate more stable and controllable. One end of the first link is hinged to the base plate, and the other end is movably mounted on the lifting plate; similarly, one end of the second link is hinged to the lifting plate, and the other end is movably mounted on the base plate. By changing the included angle between the links, the lifting plate can be moved up and down smoothly. The actuator, as the core component of the drive assembly, is located in the gap between the base plate and the moving device, avoiding interference with other components. Simultaneously, the actuator can slide on the base plate, allowing it to adaptively adjust its position when driving the lifting rod up and down, further ensuring the smoothness and precision of the lifting process.

[0022] The driver is connected to the lifting rod via its output shaft, with both ends of the lifting rod hinged to the first connecting rod. When the driver operates, it drives the lifting rod to move up and down, which, through the hinged relationship between the first and second connecting rods, allows the lifting plate to move smoothly up and down. This not only improves lifting efficiency but also ensures the stability and reliability of the lifting process. A support rod, located at the hinge point between the first and second connecting rods, is positioned between the two sets of connecting components. This not only enhances the stability of the linkage mechanism but also further improves the lifting plate's resistance to overturning during its vertical movement.

[0023] Furthermore, the drive assembly also includes a slider, the edge of which is provided with a first roller, and the base plate is provided with a guide groove adapted to the first roller. The output shaft of the driver passes through the base plate and the slider in sequence and is connected to the first connecting rod.

[0024] The first roller, positioned at the edge of the slider, mates with the guide groove on the base plate, providing precise guidance and positioning for the actuator. This ensures that the actuator moves smoothly and accurately along a predetermined trajectory when driving the lifting plate up and down, avoiding interference and damage caused by deviation or wobbling. The small contact area and low rolling friction coefficient between the first roller and the guide groove effectively reduce friction and wear during the actuator's movement, extending the service life of the actuator and the entire drive assembly, while also reducing noise and energy consumption during equipment operation. The combined use of the slider and the first roller provides additional support and stability to the actuator, ensuring the consistent stability of the lifting plate's height adjustment function.

[0025] Furthermore, two limiting frames are symmetrically arranged on the slider, and each limiting frame is equipped with a limiting slide rail adapted to the lifting rod. After the lifting rod passes through the limiting slide rail, it is connected to the first connecting rod.

[0026] The limiting slide rail on the limiting frame is compatible with the lifting mechanism, providing precise limiting for the lifting rod. This ensures that the highest position of the lifting plate is limited to a preset height during vertical movement, preventing equipment damage or safety hazards caused by excessive lifting or lowering. After passing through the limiting slide rail, the lifting rod connects to the first connecting rod, providing additional support and enhancing its stability during movement, ensuring smooth lifting.

[0027] Furthermore, a second roller is provided on the end of the first connecting rod that contacts the lifting plate, and the second roller contacts the bottom of the lifting plate;

[0028] A third roller is provided on the end of the second connecting rod that contacts the base plate, and the third roller contacts the base plate.

[0029] The second and third rollers contact the bottom of the lifting plate and the base plate, respectively. Rolling friction replaces the original sliding friction, significantly reducing friction and wear on the contact surfaces. This not only extends the service life of the first and second connecting rods, as well as the lifting plate and base plate, but also reduces noise levels during operation. Simultaneously, the roller design allows for smoother movement of the first and second connecting rods during operation. Because the rollers can roll, they can more effectively adapt to minor unevenness in the lifting plate and base plate, reducing swaying and vibration caused by friction and resistance, thus improving the stability and reliability of the equipment. It also significantly reduces the power and energy consumption required by the actuator to move the lifting plate up and down, and allows for faster response to actuator commands, thereby shortening lifting and lowering times.

[0030] The beneficial effects of this application are:

[0031] 1. The introduction of the lifting device replaces the traditional manual adjustment of the nut, significantly improving adjustment efficiency and accuracy, thereby enhancing the automation level of the entire medium-frequency heating furnace and helping to achieve a more efficient and stable production process;

[0032] 2. The limit rails on the limit frame are matched with the lifting mechanism, providing a precise limit function for the lifting rod. This ensures that the highest position of the lifting plate is limited to the preset height during the up and down movement, avoiding equipment damage or safety hazards caused by excessive lifting or lowering.

[0033] 3. The first roller set on the edge of the slider is adapted to the guide groove configured on the base plate, providing precise guidance and positioning for the driver. This ensures that the driver can move smoothly and accurately along the predetermined trajectory when driving the lifting plate to move up and down, avoiding interference and damage caused by offset or shaking.

[0040] Example 1:

[0041] like Figure 1 and Figure 2 As shown, this application embodiment provides a medium-frequency heating furnace, including a furnace body 100, a conveying table 110 for conveying bar stock, a receiving device 120 for receiving the stock, and a moving device 130 for adjusting the horizontal position of the receiving device 120, and further including:

[0042] A lifting device 200 is installed at the bottom of the receiving device 120 and is used to adjust the height of the receiving device 120.

[0043] The conveyor table 110 is provided with a V-shaped receiving groove 140 extending above the receiving device 120, through which the bar stock slides down onto the receiving device 120.

[0044] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned medium-frequency heating furnace uses a furnace body 100 for heating bar stock, a conveyor table 110 for conveying the bar stock, and a V-shaped receiving groove 140 extending above a receiving device 120 on the conveyor table 110. The bar stock can smoothly slide down through the V-shaped receiving groove 140 onto the receiving device 120, which then receives the bar stock sliding down from the conveyor table 110. A moving device 130 is used to adjust the horizontal position of the receiving device 120 to meet different production needs. A lifting device 200 is located at the bottom of the receiving device 120 and is used to automatically adjust the height of the receiving device 120, replacing the traditional manual adjustment nut method and significantly improving adjustment efficiency and accuracy.

[0045] By employing the aforementioned lifting device 200, the medium-frequency heating furnace of this application achieves automatic adjustment of the height of the receiving device 120, which not only simplifies the operation process and reduces labor intensity, but also significantly improves adjustment efficiency and accuracy. Simultaneously, the introduction of the lifting device 200 enhances the overall automation level of the medium-frequency heating furnace, contributing to a more efficient and stable production process.

[0046] Example 2:

[0047] This application provides a medium-frequency heating furnace, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0048] like Figure 2 As shown, the lifting device 200 includes:

[0049] Lifting plate 210, receiving device 120 is provided on top of lifting plate 210;

[0050] The base plate 220 is located below the lifting plate 210, and the moving device 130 is located at the bottom of the base plate 220;

[0051] A drive mechanism is mounted on the base plate 220 and connected to the lifting plate 210, used to drive the lifting plate 210 to move up and down.

[0052] A gap 230 is provided between the base plate 220 and the moving device 130, and the bottom of the drive mechanism is located within the gap 230.

[0053] In this embodiment, the lifting device 200, connected to the lifting plate 210 via a drive mechanism, enables automatic adjustment of the height of the receiving device 120, eliminating the need for traditional manual adjustment and significantly improving adjustment efficiency. This allows operators to adjust the height of the receiving device 120 more quickly and accurately to adapt to different production needs. The gap 230 between the base plate 220 and the moving device 130 provides sufficient space for the bottom of the drive mechanism, preventing interference between the drive mechanism and the base plate 220 or the moving device 130 during movement and ensuring smooth operation of the drive mechanism, further enhancing the stability and reliability of the equipment. Furthermore, the introduction of the lifting device 200 significantly improves the automation level of the medium-frequency heating furnace. By automatically adjusting the height of the receiving device 120, it enables coordinated operation with other equipment such as the conveyor table 110 and the heating furnace body 100, further improving production efficiency and quality.

[0054] Example 3:

[0055] This application provides a medium-frequency heating furnace, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0056] like Figure 2 As shown, the drive mechanism includes:

[0057] The connecting assembly 300 has a first connecting rod 310 and a second connecting rod 320 that are hinged to each other. One end of the first connecting rod 310 is hinged to the base plate 220, and the other end is movably mounted on the lifting plate 210. One end of the second connecting rod 320 is hinged to the lifting plate 210, and the other end is movably mounted on the base plate 220.

[0058] The drive assembly 400 includes a driver 410 disposed in the gap 230, a lifting rod 420 connected to the output shaft of the driver 410, both ends of the lifting rod 420 being hinged to the first connecting rod 310, and the driver 410 being able to slide on the base plate 220.

[0059] The connecting component 300 is provided in two sets, and a support rod 330 is provided between the two sets of connecting components 300. The support rod 330 is located at the hinge of the first connecting rod 310 and the second connecting rod 320.

[0060] In this embodiment, the connecting component 300 in the drive mechanism consists of a first connecting rod 310 and a second connecting rod 320 hinged together, making the height adjustment of the lifting plate 210 more stable and controllable. One end of the first connecting rod 310 is hinged to the base plate 220, and the other end is movably mounted on the lifting plate 210; while one end of the second connecting rod 320 is hinged to the lifting plate 210, and the other end is movably mounted on the base plate 220. By changing the included angle between the connecting rods, the lifting plate 210 can be moved up and down smoothly. The driver 410, as the core component of the drive assembly 400, is located in the gap 230 between the base plate 220 and the moving device 130, avoiding interference with other components. At the same time, the driver 410 can slide on the base plate 220, so that when the driver 410 drives the lifting rod 420 to move up and down, it can adaptively adjust its position, further ensuring the smoothness and precision of the lifting process.

[0061] The driver 410 is connected to the lifting rod 420 via its output shaft. Both ends of the lifting rod 420 are hinged to the first connecting rod 310. When the driver 410 operates, it drives the lifting rod 420 to move up and down. Through the hinged relationship between the first connecting rod 310 and the second connecting rod 320, the lifting plate 210 moves smoothly up and down, improving lifting efficiency and ensuring the stability and reliability of the lifting process. The support rod 330, located between the two sets of connecting components 300 at the hinge point between the first connecting rod 310 and the second connecting rod 320, enhances the stability of the linkage mechanism and further improves the anti-overturning ability of the lifting plate 210 during its up-and-down movement.

[0062] Furthermore, a second roller 340 is provided on the end of the first connecting rod 310 that contacts the lifting plate 210, and the second roller 340 contacts the bottom of the lifting plate 210;

[0063] A third roller 350 is provided on the end of the second connecting rod 320 that contacts the base plate 220, and the third roller 350 contacts the base plate 220.

[0064] The second roller 340 and the third roller 350 contact the bottom of the lifting plate 210 and the base plate 220, respectively. Rolling friction replaces the original sliding friction, significantly reducing friction and wear on the contact surfaces. This not only extends the service life of the first link 310, the second link 320, and the lifting plate 210 and base plate 220, but also reduces the noise level during equipment operation. Simultaneously, the roller design allows the first link 310 and the second link 320 to move more smoothly during operation. Because the rollers can roll, they can more effectively adapt to minor unevenness in the lifting plate 210 and base plate 220, thereby reducing swaying and vibration caused by friction and resistance, and improving the stability and reliability of the equipment. It also significantly reduces the power and energy consumption required by the driver 410 when driving the lifting plate 210 up and down, and allows for faster response to the driver 410's commands, thus shortening the lifting and lowering time.

[0065] Example 4:

[0066] This application provides a medium-frequency heating furnace, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0067] like Figure 2 As shown, the drive assembly 400 also includes a slider 430, the edge of which is provided with a first roller 440, and the base plate 220 is provided with a guide groove 450 adapted to the first roller 440. The output shaft of the driver 410 passes through the base plate 220 and the slider 430 in sequence and is connected to the first connecting rod 310.

[0068] In this embodiment, the first roller 440, located at the edge of the slider 430, is adapted to the guide groove 450 on the base plate 220, providing precise guidance and positioning for the driver 410. This ensures that the driver 410 can move smoothly and accurately along a predetermined trajectory when driving the lifting plate 210 up and down, avoiding interference and damage caused by offset or shaking. The small contact area and low rolling friction coefficient between the first roller 440 and the guide groove 450 effectively reduce the friction and wear of the driver 410 during movement, extending the service life of the driver 410 and the entire drive assembly 400, and reducing noise and energy consumption during equipment operation. The combined use of the slider 430 and the first roller 440 provides additional support and stability for the driver 410, ensuring that the height adjustment function of the lifting plate 210 remains stable.

[0069] Furthermore, two limit frames 460 are symmetrically arranged on the slider 430. Each limit frame 460 is equipped with a limit slide rail 470 that is compatible with the lifting rod 420. After the lifting rod 420 passes through the limit slide rail 470, it is connected to the first connecting rod 310.

[0070] In some embodiments of this application, the limiting slide rail 470 on the limiting frame 460 is adapted to the lifting mechanism, providing a precise limiting function for the lifting rod 420. This ensures that the highest position of the lifting plate 210 is limited to a preset height during vertical movement, avoiding equipment damage or safety hazards caused by excessive lifting or lowering. After passing through the limiting slide rail 470, the lifting rod 420 connects to the first connecting rod 310, providing additional support for the lifting rod 420 and enhancing its stability during movement, ensuring the smooth progress of the lifting process.
