Description

Technical Field

[0001] The utility model relates to the technical field of annealing equipment, in particular to annealing equipment for spheroidizing structure of cold working die steel. Background Art

[0002] Cold working die steel refers to the die steel used to deform or form metal in a cold state. It is mainly used to manufacture dies for pressing and forming workpieces in a cold state. Cold working die steel should have high hardness and wear resistance, high strength and fatigue strength, sufficient toughness, and good process performance. Annealing equipment is an important tool for annealing metals or other materials. Annealing is a material heating treatment process. By heating the material at high temperature, it is rearranged in a crystalline state, thereby eliminating stress and grain boundaries in the material and improving the plasticity and toughness of the material.

[0003] After searching, a Chinese patent with publication number CN216808920U discloses a highly safe and wear-resistant die steel annealing device. In the process of using the annealing furnace, when the furnace door is opened to take out the annealed die steel, the staff is prone to accidentally touch the furnace door. However, since the temperature of the furnace door is high at this time, the staff may be scalded, which poses a certain safety hazard. Therefore, a protective device is provided to block the surface of the protective plate when the furnace door is opened to take out the annealed die steel, thereby preventing the staff from accidentally touching the high-temperature furnace door during operation and scalding the staff, thereby improving the safety of the annealing furnace.

[0004] There are still some shortcomings in the use of the above-mentioned annealing equipment. After the mold steel is heated at high temperature, it needs to be cooled. The usual cooling method is to manually take out the heated mold steel and place it in an open place for natural cooling, which makes the cooling efficiency low, resulting in a slow processing process of the mold steel and low work efficiency. If the mold steel that has just been heated is taken out manually, there is a risk of burns, which creates a safety hazard. Utility Model Content

[0033] As attached Figure 6 As shown, the top of the cooling box 2 is fixedly connected with an air outlet pipe 14, the bottom end of the air outlet pipe 14 is fixedly connected with a fixing plate 15, the top of the fixing plate 15 is fixedly connected with a threaded sleeve 16, the inner side of the threaded sleeve 16 is threadedly connected with a mounting rod 17, the middle part of the mounting rod 17 is fixedly connected with a small-pore filter plate 18, the middle part of the mounting rod 17 is fixedly connected with a large-pore filter plate 19, the top of the large-pore filter plate 19 is arranged at the bottom end of the small-pore filter plate 18, the large-pore filter plate 19 and the rear side of the small-pore filter plate 18 are fixedly connected with a cleaning brush 20, and the other end of the mounting rod 17 is fixedly connected with a knob 21, which is conducive to double-layer filtration of the discharged exhaust gas, reducing the pollution caused by the exhaust gas to the environment, and is convenient for maintenance and cleaning after the filter plate is disassembled, and is convenient for cleaning the inner wall of the air outlet pipe 14 to reduce the adhesion of dirt particles.

[0034] As attached Figure 4 As shown, a mounting groove 22 is provided on the right side of the top of the cooling box 2 to facilitate the installation of the insulation board 23.

[0035] As attached Figure 1 As shown, the rear end of the water pump 12 is fixedly installed on the front end of the cooling box 2, and the inner side of the installation groove 22 is slidably connected with a thermal insulation plate 23. The front right side of the cooling box 2 is rotatably connected with a material taking door 25. The thermal insulation plate 23 is helpful to block the temperature of the heating box 1 and the cooling box 2.

[0036] As attached Figure 2 As shown, a feeding door 24 is rotatably connected to the right side of the heating box 1 to facilitate placing materials on the tray 5.

[0037] Working principle: When in use, first place the material on the surface of the tray 5 through the feeding door 24, then turn on the heating box 1 for heating. After heating, pull the insulation plate 23 out of the inner side of the installation groove 22, and then turn on the motor 3. The output end of the motor 3 drives the screw rod 4 to rotate, so that the screw rod 4 drives the tray 5 and the heated material to move from the inner side of the heating box 1 to the inner side of the cooling box 2, and then fill the water tank 10 with condensed water, start the water pump 12, and then the condensed water inside the water tank 10 is transported through one end of the cooling pipe 11, and the water flow is transported back to the inside of the water tank 10 by the other end of the cooling pipe 11, so as to form a water circulation for water cooling. In the process of water flow transportation, because the cooling pipe 11 is in close contact with the cooling box 2, it is convenient to cool the inside of the cooling box 2 attached to the shell of the cooling box 2. The heat on the body is cooled down, and then the air cooler 9 is turned on, so that the air cooler 9 absorbs wind through the air suction slot 8. After the wind passes through the ventilation plate 13, it blows to the inside of the cooling box 2, thereby reducing the accumulation of heat, which is beneficial to air cooling and cooling, thereby improving the cooling efficiency. When the exhaust gas generated in the cooling process is discharged through the air outlet pipe 14, it first passes through the large-pore filter plate 19 and is then blocked by the large-pore filter plate 19, and then passes through the small-pore filter plate 18 and is blocked by the small-pore filter plate 18, which is convenient for double-layer filtration of the exhaust gas. When the filter plate is disassembled, the knob 21 is turned to make the knob 21 drive the mounting rod 17 to rotate, and the mounting rod 17 drives the small-pore filter plate 18 and the large-pore filter plate 19 to rotate. During the rotation process, the large-pore filter plate 19 and the small-pore filter plate 18 drive the cleaning brush 20 to rotate, thereby facilitating the cleaning of the inner wall of the air outlet pipe 14.
