Description

Technical Field

[0001] This utility model relates to the field of forging furnace technology, specifically to a furnace cavity structure for uniformly heating hot forging materials. Background Technology

[0002] Forging is a processing method that uses hammering or pressurizing to give metal objects a certain shape and size and change their physical properties. Forging furnaces are used to heat the metal during forging.

[0003] When metal is fed into the furnace from the furnace opening for heating, there is a large temperature difference between the bottom and the surface of the metal due to uneven heating. Excessive temperature difference will cause the physical properties of the metal to be different at different temperature locations during forging. Furthermore, excessive temperature will cause the oxide scale thickness in the high-temperature zone to be up to twice that in the low-temperature zone, resulting in a rough metal surface.

[0017] Please see Figure 1-2 As shown, this utility model is a furnace cavity structure for uniformly heating hot forging materials, comprising: The furnace wall is 100 mm thick, and an inlet 110 is provided in the furnace wall 100 mm thick. The tilting mechanism includes a cantilever plate 210, a first motor 220, a lead screw 230, a threaded column 240, a second motor 250, and a circular plate 260. The cantilever plate 210 is fixedly connected to the bottom of the inlet 110. The first motor 220 is fixedly connected to the bottom of the cantilever plate 210. The lead screw 230 is fixedly connected to the power output end of the first motor 220. The threaded column 240 is threadedly connected to the lead screw 230 and slides inside the cantilever plate 210. The second motor 250 is fixedly connected above the threaded column 240. The circular plate 260 is fixedly connected to the power output end of the second motor 250. A clamp is fixedly connected to the surface of the circular plate 260. After one end of the metal is fixed by the clamp, the first motor 220 is started to drive the lead screw 230 to rotate. The lead screw 230 drives the threaded column 240 to slide into the furnace. Then the second motor 250 is started to drive the circular plate 260 to rotate. The circular plate 260 drives the clamp to make the metal rotate in the furnace, so that the metal is heated evenly on both sides in the furnace. A square plate 241 is fixedly installed on the top of the threaded column 240, and a vertical plate 242 is fixedly installed on the top of the square plate 241. The second motor 250 is fixedly connected to the side wall of the vertical plate 242. The threaded column 240 drives the square plate 241 to slide, and the square plate 241 drives the vertical plate 242 to slide, thereby causing the second motor 250, the circular plate 260 and the clamp on the surface of the circular plate 260 to slide. The bottom ends of the cantilever plate 210 are respectively fixedly connected to the lower hanging plates 211. The first motor 220 is fixedly connected to the surface of one of the lower hanging plates 211. The lead screw 230 is rotatably connected between the two lower hanging plates 211. The first motor 220 drives the lead screw 230 to rotate between the lower hanging plates 211. The cantilever plate 210 has a rectangular hole 212 on its surface. The threaded column 240 slides in the rectangular hole 212. The bottom sides of the cantilever plate 210 are fixedly connected to the diagonal braces 213. The end of the cantilever plate 210 near the inlet 110 is fixedly connected to the bracket 270. The screw 230 rotates and drives the threaded column 240 to slide in the rectangular hole 212. The diagonal braces 213 make the cantilever plate 210 more stable. The other end of the metal is placed on the bracket 270. Working principle: After one end of the metal is fixed by the clamp, the other end of the metal is placed on the bracket 270. The first motor 220 is started to drive the lead screw 230 to rotate between the lower hanging plates 211. The rotation of the lead screw 230 drives the threaded column 240 to slide in the rectangular hole 212. The threaded column 240 drives the square plate 241 to slide. The square plate 241 drives the vertical plate 242 to slide. The vertical plate 242 drives the second motor 250, the round plate 260 and the clamp on the surface of the round plate 260 to slide into the furnace, so that the metal slides into the furnace. Then the second motor 250 is started to drive the round plate 260 to rotate. The round plate 260 drives the clamp on the surface of the round plate 260 to rotate, which in turn drives the metal to rotate. This makes the upper and lower surfaces of the metal heat evenly in the furnace, avoiding temperature differences on the metal surface that would cause different physical properties after forging. It also avoids large differences in oxide scale thickness, thereby improving the smoothness of the surface. Please see Figure 1-2 As shown, this embodiment, based on the above embodiment, further includes: The closing mechanism includes a sliding door 310, a sliding column 320, and a connecting rod 330. There are two sliding doors 310, which are slidably connected inside the inlet 110. There are two sliding columns 320, which are fixedly connected to the bottom of the surfaces of the two sliding doors 310 respectively. The sliding columns 320 slide on the surface of the furnace wall 100. There are two connecting rods 330, with the two ends of two square plates 241 rotatably connected to the ends of the sliding columns 320 and the side walls of the threaded columns 240 respectively. The square plates 241 slide towards the inlet 110, causing one end of the connecting rod 330 to move, causing the other end of the connecting rod 330 to drive the sliding column 320 to slide, and the sliding column 320 causes the sliding door 310 to slide open. The sliding column 320 has a rotating groove 321 at its end, and the square plate 241 has a side groove 243 fixedly provided on its side. The two ends of the connecting rod 330 are rotatably connected in the rotating groove 321 and the side groove 243, respectively. The square plate 241 slides and drives one end of the connecting rod 330 to rotate in the side groove 243 and move accordingly, so that the other end of the connecting rod 330 rotates in the rotating groove 321 and drives the sliding column 320 to slide. A sliding groove 101 is provided on the furnace wall 100 near the bottom opening of the inlet 110. The sliding column 320 slides in the sliding groove 101, and the sliding column 320 drives the sliding door 310 to slide. Working principle: When the square plate 241 slides into the furnace, it drives one end of the connecting rod 330 to rotate in the side groove 243 and move accordingly. This causes the other end of the connecting rod 330 to rotate in the rotating groove 321 and drive the sliding column 320 to slide in the sliding groove 101. The sliding column 320 drives the sliding door 310 to slide and close. After the metal heating is completed, the first motor 220 drives the lead screw 230 to rotate, causing the threaded column 240 to drive the square plate 241 to slide towards the inlet 110. The square plate 241 drives one end of the 3303 to move towards the inlet 110, causing the other end of the connecting rod 330 to drive the sliding column 320 to slide to both sides. The sliding column 320 drives the sliding door 310 to slide to both sides and open, improving the furnace sealing, preventing heat leakage from the inlet 110, and reducing energy consumption.
