Problems solved by technology

[0002] At present, in the field of forging, the inner hole of the forging is basically changed from drilling to hot punching, but for the inner hole of the double oil groove forging, it is difficult to realize the hot punching process. The main reason is that the oil groove is deformed after hot punching, resulting in The width is eight-shaped and the bottom of the oil tank is uneven, and the outside is low and the inside is high. Therefore, in the domestic forging field, the inner hole of the double oil tank forging still adopts the drilling process. This process is time-consuming and labor-intensive, and the cost increases. Low

Embodiment 1

[0018] The double oil tank forging hot stamping process is characterized in that it includes the following process steps:

[0019] ①. Blanking: Set the weight of raw materials on the shearing machine to 3.0kg, and the tolerance is controlled within ±10g. The shearing machine is used to unload the material, and then the shearing machine is used to cut and divide the material.

[0020] ②. Heating: The intermediate frequency furnace is heated to 1000 ° C. The temperature should not be too high or too low. If the temperature is too high, the product will be overheated, and if the temperature is too low, the product will be insufficient;

[0021] ③Blank making: use 400T friction press to make the billet, and the diameter of the billet is smaller than the diameter of the mold cavity by 2mm;

[0022] ④ Forming: Forming with a 400T friction press, preheating the forging mold for 10-15 minutes before forming, and then putting the heated billet into the mold cavity for forging. The fina...

Embodiment 2

[0029] The double oil tank forging hot stamping process is characterized in that it includes the following process steps:

[0030] ①. Blanking: Set the weight of raw materials on the shearing machine to 5kg, and the tolerance is controlled within ±10g. The shearing machine is used to unload the material, and then the material is cut and divided by the shearing machine.

[0031] ②. Heating: The intermediate frequency furnace is heated to 1100°C. The temperature should not be too high or too low. If the temperature is too high, the product will be overheated, and if the temperature is too low, the product will be insufficient;

[0032] ③Blank making: use 400T friction press to make the billet, and the diameter of the billet is 2.5mm smaller than the diameter of the mold cavity;

[0033] ④ Forming: Forming with a 400T friction press, preheating the forging mold for 10-15 minutes before forming, and then putting the heated billet into the mold cavity for forging. The final forging...

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a hot stamping process for forgings with double oil grooves. Background technique [0002] At present, in the field of forging, the inner hole of the forging is basically changed from drilling to hot punching, but for the inner hole of the double oil groove forging, it is difficult to realize the hot punching process. The main reason is that the oil groove is deformed after hot punching, resulting in The width is eight-shaped and the bottom of the oil tank is uneven, and the outside is low and the inside is high. Therefore, in the domestic forging field, the inner hole of the double oil tank forging still adopts the drilling process. This process is time-consuming and labor-intensive, and the cost increases. Low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double oil tank forging hot stamping process with simpl...
