Embodiment 1
[0027] This embodiment provides a heat treatment method for a high air pressure drilling tool down-the-hole drill bit. The method includes the following steps:
[0028] S1. Heat the original DTH bit to 750°C to 850°C in a heating furnace, forge the heated DTH original, and put it into the forging die for forming die forging after the original DTH is basically formed. ;
[0029] S2, put the forged down-the-hole drill bit into the heating equipment, heat it under the condition of 900°C-950°C for 4h-5h, then put it in the air to cool the down-the-hole drill bit, and then heat it under the condition of 650°C-700°C Heating at low temperature for 4h~5h, stop the heating and cool down the down-the-hole drilling furnace to below 200℃;
[0030] S3, perform numerical control processing on the out-of-the-hole down-the-hole drill bit according to the size requirements;
[0031] S4, put the DTH drill bit after CNC machining into the carburizing furnace for heating, and carry out carburiz...
Embodiment 2
[0041] This embodiment provides a heat treatment method for a high air pressure drilling tool down-the-hole drill bit. The method includes the following steps:
[0042] S1, the original DTH bit is heated to 780°C in a heating furnace, and the heated DTH original is forged. After the original DTH is basically formed, it is put into the forging die for forming die forging. Among them, the forging of the heated original down-the-hole drill can be forged with a forging machine of 0.75T-3T (ton) according to the size of the down-the-hole drill.
[0043] S2, put the forged down-the-hole drill bit into the heating equipment, heat it at 930°C for 4 hours, then place it in the air to cool the down-the-hole drill bit, and then heat it at 680°C for 4 hours, then stop heating Finally, cool the down-the-hole drill furnace to below 200°C. Among them, the equipment used in the two heating processes is "Aichelin multi-purpose furnace", and the time of the two heatings can be slightly extende...
Embodiment 3
[0049] This embodiment provides a high air pressure drilling tool down-the-hole drill bit, which is manufactured using the heat treatment method described in Embodiment 1 or Embodiment 2.
