Embodiment Construction
[0016] The present invention will be further described now in conjunction with accompanying drawing
[0017] A lubricating process before forging that avoids carbon deposits on metal parts, characterized in that the lubricating oil in forging is replaced by a saponification solution, the saponification solution is pure water with a conductivity of ≤15us / cm and a weight ratio of 6% to 8% It is formulated with water-based metalworking fluid; the saponified liquid evenly covers the metal surface involved in forging and is dried; and it is completed by the following steps:
[0018] ① Spray the saponification solution at a temperature of 50°C to 60°C on the inner and outer surfaces of the workpiece for 80 seconds to 130 seconds;
[0019] ② Under the action of 5bar compressed air, suck away the saponification liquid accumulated in the depression of the workpiece; realize the uniform coverage of the saponification liquid on the surface of the workpiece;
[0020] ③ Drying: The workpi...

The invention discloses a forging pre-lubrication process for preventing a metal part from gathering carbon and a production device, belongs to a metal surface treatment technology, and relates to a forging pre-lubrication technology. The key point is as follows: saponification liquid replaces lubrication oil involved in forging and is uniformly covered on a metal surface involved in forging and dried; and the forging pre-lubrication process is finished by specific steps. A lubrication device consists of a saponification liquid spraying device, a liquid removal device, a drying device and a rotary positioning device and is provided with a workpiece conveying mechanism, wherein the conveying mechanism clamps a workpiece and enables the workpiece to move and penetrate step by step to finish the whole process; and a saponification liquid heating device is arranged in the saponification liquid spraying device. According to the forging pre-lubrication process, during die-forging of the part, the lubrication oil is not used, so that the energy consumption is reduced, air pollution of lampblack production to a production workshop is avoided, and a phenomenon that carbon is gathered on the part is avoided effectively; and therefore, a phenomenon that oil dirt and the gathered carbon on the part are cleaned by a cleaning agent in the subsequent process is avoided.
Description
technical field [0001] The invention belongs to the field of metal surface treatment technology and forging technology; to be precise, it relates to the lubrication technology before die forging in the forging industry. Background technique [0002] When metal parts are molded forging, in order to reduce the probability of damage to the mold by the workpiece, lubricating oil must be applied to the workpiece. However, during the forging process, the friction between the workpiece and the die will generate high temperature, causing the lubricating oil to carbonize and remain on the surface of the workpiece to form carbon deposits. At present, carbon deposition is still a cleaning problem in the world. Moreover, lubricating oil will volatilize a large amount of soot during the carbonization process, which will pollute the environment of the workshop and affect the health of workers. [0003] Contents of the invention [0004] The present invention provides a pre-forging l...
