[0012] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0013] This application discloses an ultra-high temperature infrared heating furnace for the production of automotive sealing components.

[0014] Reference Figures 1 to 7An ultra-high temperature infrared heating furnace for automotive sealing parts production includes a frame 1, which includes a lifting platform 11 and an electrical control box 12. The lifting platform 11 is equipped with a heating furnace 2. The heating furnace 2 has inlet and outlet traction systems 3 at both ends. The heating furnace 2 includes an outer shell 21 and heating tubes 22 located within the outer shell 21. The heating tubes 22 include an inner tube 221 and an outer tube 222, with electric heating tubes 223 evenly installed between them. The ends of the electric heating tubes 223 and the outer tube 222 are mounted on positioning plates 23. The inner tube 221 extends through the positioning plates 23 to both ends of the outer shell 21. The outer shell 21 includes an upper shell 211 and a lower shell 212 hinged together. The two ends of the outer shell 21 are equipped with guide pipes 24. The upper shell 211 has a drive mechanism on its side that opens to the lower shell 212. The combined drive assembly 25; the inlet and outlet traction system 3, which is symmetrically arranged at both ends of the heating furnace 2, includes a seat 31 and a traction mechanism 32 mounted on the seat 31, wherein the seat 31 is flexibly mounted on the lifting platform 11, and the traction mechanism 32 includes several sets of traction wheels 321 and a servo motor 322 that drives the traction wheels 321 to rotate synchronously; the lifting platform 11 includes a mounting plate 111 and a support frame 112 symmetrically distributed at the bottom of the mounting plate 111, wherein a hydraulic cylinder 113 that drives the mounting plate 111 to lift is mounted on the support frame 112, and a connecting frame 114 that is slidably connected to the seat 31 for lifting is fixedly mounted on both sides of the mounting plate 111, wherein an adjustment mechanism 115 that drives the seat 31 to lift on the connecting frame 114 is mounted on the mounting plate 111. Before starting the equipment, the height of the mounting plate 111 is adjusted by the hydraulic cylinder 113 of the lifting platform 11, and then the adjusting turntable 1154 of the adjusting mechanism 115 is rotated to drive the seat 31 to rise and fall along the connecting frame 114, so that the heating furnace 2 and the inlet and outlet traction system 3 are adapted to the specifications of the aluminum strip and steel strip to be processed; the driving component 25 drives the upper shell 211 to open around the hinge with the lower shell 212, and installs and removes the heating tube 22 inside the outer shell 21. The product is placed into the inner tube 221 of the heating furnace 2 through the guide pipe 24. After closing the upper shell 211, the equipment is started through the electrical control box 12; the electric heating tube 223 heats the product evenly between the inner and outer tubes 222. At the same time, the servo motor 322 drives the drive wheel 3211 of the traction mechanism 32 to rotate, and drives the driven wheel 3212 to rotate synchronously through the transmission belt 3213. The traction wheel 321 smoothly transports the heated product, and the entire process of automated heating and conveying is completed.

[0015] Reference Figures 1 to 7The drive assembly 25 includes a bracket 251 fixed to the bottom of the mounting plate 111, wherein the bracket 251 extends to the rear side of the outer shell 21. A rotating frame 252 is fixedly connected to the rear side of the upper shell 211, and a drive cylinder 253 is mounted on the bracket 251 to drive the upper shell 211 to rotate at the rear hinge point of the lower shell 212. The cylinder body of the drive cylinder 253 is hinged to the bracket 251, and the piston rod is hinged to the rotating frame 252. When it is necessary to install and remove the heating tube 22 inside the outer shell 21, the piston rod of the drive cylinder 253 extends or retracts. Because its cylinder body is hinged to the bracket 251 at the bottom of the mounting plate 111 and the piston rod is hinged to the rotating frame 252 at the rear side of the upper shell 211, it will drive the upper shell 211 to rotate around the rear hinge point with the lower shell 212, thereby realizing the opening and closing of the furnace body and facilitating internal maintenance of the equipment.

[0016] Reference Figures 1 to 7 The feed inlet 24 includes an upper tube 241 and a lower tube 242, which are respectively fixedly connected to one end of the upper shell 211 and the lower shell 212. The opposing surfaces of the upper tube 241 and the lower tube 242 are both grooves with semi-circular cross-sections, and the top of the upper tube 241 is also provided with a heat dissipation vent 243. When the furnace is closed, the upper tube 241 of the upper shell 211 and the lower tube 242 of the lower shell 212 fit together, and the semi-circular grooves on their opposing surfaces form a complete channel, providing feeding and discharging guidance for aluminum strips and steel strips. During the heating process, the heat dissipation vent 243 at the top of the upper tube 241 discharges excess heat from the furnace in real time, avoiding excessive local temperature and ensuring uniform heating of the product.

[0017] Reference Figures 1 to 7The base 31 adopts an L-shaped main board 311. Several sets of traction wheels 321 are mounted on the top of the main board 311. The two ends of the traction wheels 321 are rotatably mounted on the mounting bases 323, and the bottoms of the mounting bases 323 at both ends are connected by a base plate 324. The traction wheel 321 includes a driving wheel 3211 and several sets of driven wheels 3212. One end of the driving wheel 3211 is driven by a servo motor 322 at the bottom. The end of the driving wheel 3211 away from the servo motor 322 is connected to the driven wheel 3212 by a transmission belt 3213. The driven wheels 3212 are also synchronously connected to each other by a transmission belt 3213. A U-shaped protective cover 325 is mounted on the top of the traction wheel 321, and a connecting plate 326 is mounted on the bottom. A slide rail 3261 that is slidably connected to the connecting frame 114 is mounted on the connecting plate 326, and the top of the connecting plate 326 is fixedly connected to the mounting base 323 on the side of the traction wheel 321 away from the servo motor 322. The connecting frame 114 includes plates 1141 fixedly installed at both ends of the bottom of the mounting plate 111. Triangular reinforcing plates 1142 are installed on the inner side of the plates 1141 and the bottom of the mounting plate 111. Limiting blocks 1143 are installed on the outer side of the plates 1141, and limiting grooves 1144 adapted to the slide rails 3261 of the connecting plate 326 are provided on the limiting blocks 1143. The adjustment mechanism 115 includes a first L-shaped plate 1151 fixed to the outside of the main board 311 and a second L-shaped plate 1152 fixed to the top surface of the mounting plate 111. An adjustment rod 1153 passes through the first L-shaped plate 1151 and the second L-shaped plate 1152. One end of the adjustment rod 1153 is rotatably connected to the second L-shaped plate 1152 through a bearing. The other end of the adjustment rod 1153 passes through the first L-shaped plate 1151 and the external thread on the adjustment rod 1153 is adapted to the internal thread on the inner side of the first L-shaped plate 1151. An adjustment turntable 1154 is also installed on the adjustment rod 1153 located at the extended end of the first L-shaped plate 1151.After the servo motor 322 starts, it drives the drive wheel 3211 to rotate, and transmits the power to each driven wheel 3212 through the transmission belt 3213. The inner side of the transmission belt 3213 is provided with a tooth surface that matches the gear at the end of the traction wheel 321, so that all traction wheels 321 rotate synchronously to stably transport products. The U-shaped protective cover 325 protects the traction wheel 321. The slide rail 3261 on the connecting plate 326 cooperates with the limiting slide groove 1144 of the limiting block 1143 of the connecting frame 114 to provide guidance for the lifting and lowering of the seat 31. Rotating the adjusting turntable 1154 drives the adjusting rod 1153 to rotate. By using the threaded cooperation between the adjusting rod 1153 and the first L-shaped plate 1151, the seat 31 is driven to slide up and down along the connecting frame 114 to accurately adjust the height of the traction system. The triangular reinforcing plate 1142 of the connecting frame 114 improves the structural stability.

[0018] Reference Figures 1 to 7 A set of connecting seats 116 is installed at each end of the bottom of the mounting plate 111. The two sets of connecting seats 116 are perpendicularly distributed along the length and width directions of the mounting plate 111. The connecting seats 116 distributed along the length direction include two symmetrically distributed T-shaped frames 1161 and a rotating shaft 1162 rotatably connected between the T-shaped frames 1161. A slider 1163 is fitted on the rotating shaft 1162 of the connecting seats 116 distributed along the length direction of the mounting plate 111. The bottom of the slider 1163 is hinged to the output shaft of the hydraulic cylinder 113. A base plate 1164 is fixed to the bottom of the T-shaped block of the connecting seats 116 distributed along the width direction of the mounting plate 111. The bottom center of the base plate 1164 is hinged to the output shaft of the hydraulic cylinder 113. Guide rods 1165 are also connected to both ends of the bottom of the base plate 1164. The guide rods 1165 penetrate the support frame 112 longitudinally. When the hydraulic cylinder 113 is started, its output shaft pushes or pulls the connecting seat 116 at the bottom of the mounting plate 111. The connecting seats 116 distributed along the length direction cooperate with the rotating shaft 1162 through the slider 1163, and the connecting seats 116 distributed along the width direction cooperate with the guide rod 1165 through the base plate 1164, together driving the mounting plate 111 to rise and fall smoothly. The guide rod 1165 penetrates the support frame 112 longitudinally, further ensuring the verticality and stability of the mounting plate 111 during the lifting process, and realizing the precise adjustment of the overall height of the heating furnace 2.

[0019] Working principle: During operation, the hydraulic cylinder 113 at the bottom of the lifting platform 11 drives the mounting plate 111 to rise and fall. Combined with the adjustment turntable 1154 of the adjustment mechanism 115 rotating the adjustment rod 1153, the seat 31 slides up and down along the limiting slide groove 1144 of the connecting frame 114, so that the heating furnace 2 and the inlet and outlet traction system 3 are adjusted to the height suitable for the product. Then, the aluminum strip, steel strip and other products waiting to be heated are placed into the inner tube 221 of the heating furnace 2 through the channel formed by the combination of the upper tube 241 and the lower tube 242 of the guide pipe 24 at one end. Then, the heating is carried out through the electrical control box. 12. Start the equipment; After the electric heating tube 223 is powered on, it heats up evenly between the inner tube 221 and the outer tube 222 of the heating tube body 22, and heats the product inside the tube quickly. At the same time, the servo motor 322 drives the drive wheel 3211 of the traction mechanism 32 to rotate, and drives each driven wheel 3212 to rotate synchronously through the transmission belt 3213. The traction wheel 321 smoothly conveys the heated product out of the heating furnace 2 through the other end guide pipe port 24. The heat dissipation port 243 at the top of the upper tube body 241 can balance the temperature inside the furnace in real time, realizing the automatic heating and precise conveying of the product throughout the process.

[0020] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
