Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, and in particular to an annealing device for high-speed steel production. Background Technology

[0002] High-speed steel is a tool steel with high hardness, high wear resistance, and high hot hardness, and is widely used in the manufacture of cutting tools, molds, etc. Annealing is an essential heat treatment process in the production of high-speed steel, the purpose of which is to eliminate internal stress, reduce hardness, and improve machinability.

[0003] When using the above technology, the following technical problems were found in the existing technology: the traditional annealing process generally adopts air cooling or wind cooling, which has a slow cooling rate (usually lower than water pump two (10)℃ / min), resulting in a long production cycle and low production efficiency. More importantly, air cooling and wind cooling are significantly affected by factors such as ambient temperature and airflow distribution, making it difficult to ensure cooling uniformity. This can easily cause cooling differences between the workpiece surface and core, and between different parts, leading to uneven structure and uneven hardness distribution, which seriously affects the consistency of product performance. Therefore, we designed an annealing device for high-speed steel production to provide another technical solution to the above technical problems. Utility Model Content

[0024] Please refer to Figures 1-4 An annealing device for high-speed steel production includes a frame 1, a cooling box 2 fixed to the top of the frame 1, a water inlet pipe 3 fixed to the top of the cooling box 2, a water outlet pipe 4 fixed to one end of the cooling box 2, a feeding cylinder 5 fixed to the bottom of the frame 1, a guide bucket 11 fixed to the bottom of the feeding cylinder 5, a filter box 6 fixed to the bottom of the guide bucket 11, a discharge pipe 15 fixed to one end inside the filter box 6, a guide plate 8 fixed to the top of the inner side of the feeding cylinder 5, a plurality of nozzles 9 fixed to the bottom of the guide plate 8, a second water pump 10 fixed to the bottom of the cooling box 2, the output end of the second water pump 10 being connected to the plurality of nozzles 9 via a hose, and the input end of the second water pump 10 being fixed to the cooling box 2.

[0025] When the high-speed steel is placed inside the feed cylinder 5 for annealing, coolant is injected into the cooling tank 2. The cooling tank 2 is then started to control the temperature of the coolant inside the cooling tank 2. The water pump 10 is then started to transport the controlled coolant inside the cooling tank 2 to the inside of the guide plate 8. The coolant is then sprayed onto the surface of the high-speed steel through the nozzle 9 for annealing. At this time, the annealed coolant flows from the surface of the high-speed steel into the guide bucket 11 and the filter box 6 for processing.

[0026] Several arc-shaped support rods are rotatably fixed at the bottom of the inner side of the feed cylinder 5, and a rotating shaft 7 is rotatably connected to the outer side of the arc-shaped support rods;

[0027] The high-speed steel is supported by an arc-shaped support rod, while the rotating shaft 7 effectively improves the movement of the high-speed steel.

[0028] The filter box 6 has a second fine filter screen 13 and a first coarse filter screen 14 slidably connected inside. The filter holes of the second fine filter screen 13 are smaller than those of the first coarse filter screen 14.

[0029] A water pump 12 is fixed to one side of the filter box 6. The input end of the water pump 12 is fixed to the bottom end of the filter box 6, and the output end of the water pump 12 is connected to the cooling box 2 through a hose.

[0030] The annealed coolant is filtered by the second fine filter screen 13 and the first coarse filter screen 14, and then the filtered coolant flows into the bottom of the filter box 6. At this time, the water pump 12 is started to transport the filtered coolant into the interior of the cooling tank 2 for recycling, while some of the precipitated coolant is discharged through the discharge pipe 15.

[0031] Manual valves are installed on the outside of the discharge pipe 15 and the water outlet pipe 4. Support columns 16 are fixed at the bottom of both sides of the bottom of the frame 1. The manual valves facilitate the discharge of coolant from the cooling box 2 and the filter box 6.

The controller is also electrically connected to water pump 2 10, water pump 1 12, and cooling tank 2 via wires. When the controller is plugged into the external power source, it starts the cooling tank 2, thereby cooling the coolant inside the cooling tank 2. Then, water pump 2 10 is started to spray the cooled coolant inside the cooling tank 2 onto the surface of the high-speed steel. The annealed coolant is filtered through the second fine filter screen 13 and the first coarse filter screen 14. Finally, water pump 1 12 is started to transport the filtered coolant back into the cooling tank 2. This cycle is repeated, effectively improving the annealing effect of the device on the high-speed steel and effectively saving water resources.
