Description

Technical Field

[0001] This utility model relates to the field of bogie hearth furnaces, specifically to a bogie hearth furnace structure that facilitates feeding. Background Technology

[0002] The bogie hearth furnace is a standard energy-saving periodic furnace, mainly used for quenching, annealing, aging of workpieces, and heat treatment of various mechanical parts.

[0003] The main structure of the bogie hearth furnace is that the furnace bottom is a movable bogie. The bogie is loaded with materials outside the furnace, and the heating elements are placed on special pads. Then, the traction mechanism pulls the bogie into the furnace for heating. After heating, the traction mechanism pulls the bogie out of the furnace to unload the materials. Afterward, or a crane is used to lift the heated workpieces onto forging equipment for processing.

[0004] When annealing certain metal parts, annealing materials need to be added. For example, adding alum during the annealing process of copper wire can help the copper wire anneal better and prevent it from turning black and having a grainy texture. However, the existing bogie furnace structure cannot open the furnace door during the annealing process. Opening the furnace door will change the rate of temperature change inside the furnace, which will reduce the annealing effect. Furthermore, opening the furnace door when the furnace temperature is too high will also pose a safety hazard to the workers. Therefore, a bogie furnace structure is needed that allows materials to be added into the furnace while the furnace door is open. Utility Model Content

The trolley track is installed at the bottom of the furnace body. The trolley is mounted on the trolley track and can slide back and forth along the track. The furnace door is installed on one side of the trolley. A heat insulation layer is provided on the side of the furnace door near the trolley track. The size of the heat insulation layer corresponds to the size of the furnace chamber. A feeding notch is provided on the heat insulation layer. A tilting door is rotatably connected to the feeding notch. A telescopic rod is connected to one side of the tilting door. A cavity is provided inside the furnace door. Through holes are provided on the left and right sides of the cavity. A rotating block is provided inside the cavity. A threaded hole is provided on the side of the rotating block near the heat insulation layer. One end of the telescopic rod passes through the through hole and is threadedly connected to the threaded hole. A rotating handle is connected to the other end of the rotating block.

[0025] Example 1

[0026] Reference Figure 1-2 A trolley furnace structure for easy feeding includes a furnace body 1, a trolley 2, a trolley track 3, and a furnace door 4. The furnace body 1 contains a furnace chamber 1-1. The trolley track 3 is installed at the bottom of the furnace body 1. The trolley 2 is installed on the trolley track 3 and can slide back and forth along the track 3. The furnace door 4 is installed on one side of the trolley 2. A heat insulation layer 5 is provided on the side of the furnace door 4 closest to the trolley track 3. The size of the heat insulation layer 5 corresponds to the size of the furnace chamber 1-1. A feeding notch 6 is provided on the heat insulation layer 5. A tilting door 7 is rotatably connected to the feeding notch 6. One side of the tilting door 7 is connected to... The telescopic rod 8 is provided. A cavity 4-3 is set inside the furnace door 4. Through holes 4-4 are set on the left and right sides of the cavity 4-3. A rotating block 9 is set inside the cavity 4-3. A threaded hole 9-1 is set on the side of the rotating block 9 near the heat insulation layer 5. One end of the telescopic rod 8 passes through the through hole 4-4 and is threadedly connected to the threaded hole 9-1. The other end of the rotating block 9 is connected to a rotating handle 10. The rotating handle 10 is located on one side of the furnace door 4. A feeding port 4-1 is set on one side of the furnace door 4. A feeding channel 4-2 is also set inside the furnace door 4. The feeding channel 4-2 is connected to the unloading notch 6.

[0027] Preferably, a hopper 11 is provided around the outer periphery of the feeding port 4-1.

[0028] Preferably, a heat insulation cover plate 11-1 is provided on the hopper 11, and the heat insulation cover plate and the hopper 11 are connected by a hinge structure.

[0029] Preferably, the bottom of the notch 6 on the insulation layer 5 has a beveled structure.

[0030] Preferably, the cross-section of the flip door 7 is trapezoidal.

[0031] In actual operation, when it is necessary to add annealing auxiliary materials to the furnace during the annealing process, the material can be put into the feeding port 4-1 from the hopper 11. The material will slide from the feeding port 4-1 into the bottom of the discharge notch 6. Then, rotate the rotating handle 10. The rotating handle 10 drives the rotating block 9 to rotate. When the rotating block 9 rotates, the telescopic rod 8 threaded to the rotating block 9 will move laterally. The flip door 7 is lifted by the telescopic rod 9, so that a gap appears between the flip door 7 and the discharge notch 6. At this time, the material will slide down the inclined side of the discharge notch 6 onto the annealed metal on the trolley.

[0032] Example 2

By fitting the bearing 12 around the outer periphery of the rotating block 9, the position of the rotating block 9 can be fixed, preventing one end of the rotating block 9 from tilting when the rotating handle 10 is rotated, which could cause the telescopic rod 8 to break when it moves laterally with the rotating handle.
