Description

Technical Field

[0001] The invention belongs to the technical field of hot forging dies, and in particular relates to an automatic lubricating and cleaning hot forging die device. Background Art

[0002] The hot forging process can improve the strength, hardness, toughness, precision and surface finish of forgings by changing the grain structure of the metal. Before forging, lubricating the die can not only promote the flow of metal, fill the die cavity with material, facilitate demolding of forgings, reduce the phenomenon of sticking to the die, but also effectively reduce wear and extend the service life of the die. Die lubrication can also clean the waste on the surface of the die and impurities such as scale produced by the forgings. However, if the lubricant is applied too much or unevenly, it will hinder the flow of metal and cause defects such as folding, eddy currents or mixed crystals in the forgings. Therefore, the spraying of the lubricant needs to be precisely controlled to achieve the right amount and uniformity.

[0003] After analyzing and studying a variety of hot forging dies, it was found that it is difficult to fully clean the residual waste on the die surface during the die lubrication process, which affects the quality of the forgings and the life of the die. For example, the Chinese patent document with publication number CN103752632B discloses a press die lubrication device, which realizes the cooling and lubrication of the die through a jet device (with an air pump and a jet pipe) and an inkjet device (stirring device, ink pump and inkjet pipe). Although the scheme proposes a method for die lubrication, it is mainly suitable for press dies with simple structures. For dies with complex structures, especially dies with variable surface shapes, it is difficult to fully clean the residual waste on the die surface by relying solely on the cooperation of the jet device and the inkjet device, resulting in surface isolation during the lubrication process. It is difficult to achieve sufficient and uniform lubrication if the lubrication is not in place, which affects the quality of the forgings and shortens the service life of the die. Another example is the Chinese patent document with publication number CN107350188B, which discloses an improved automatic cleaning device for lubricant of wheel hub forging dies. The device utilizes the combined action of a servo motor and a hydraulic cylinder to realize die rotation and automatic cleaning of lubricant. The die is cleaned by designing a steel ball brush and a lubricant scraper. The scraper is customized through a wire cutting process and can only cope with specific dies. For complex dies with depressions, protrusions or non-standard curves on the surface, the scraper cannot fully fit with the die surface, resulting in incomplete cleaning and poor cleaning effect, which affects the quality of the forgings.

The second rotary driver 505 changes the driving direction of the second gear 504 to achieve horizontal adjustment of the nozzle 509 to the left and right, so as to adapt to the width of the mold body 301. When in use, the lubricating liquid can be sprayed more fully on each surface of the mold body 301 through the alternating conversion of the rotation direction of the second driver, so that the sticky impurities on the mold surface can be fully carried away by the lubricating liquid.

[0027] See also Figure 6 and Figure 7As shown, further, in order to realize the flexible adjustment of the lubricating liquid spraying path, ensure that the lubricating liquid can be fully and evenly sprayed and distributed on each surface of the mold body 301, so that the mold surface can be cleaned more thoroughly.

When the lubricating fluid needs to be discharged, the control valve 210 on the discharge mechanism is opened, the lubricating fluid is discharged and takes away the waste material in the die and the oxide scale of the forging, thereby achieving effective cleaning of the die. If cleaning is not required, the control valve 210 of the discharge mechanism is closed, which will not affect the normal forging process of the forging.

[0034] In summary, with the cooperation of various components, the device uses the conveying module to continuously transfer the lubricating liquid in the oil tank to the nozzle 509 to achieve spray lubrication of the mold body 301.

Then, through the coordinated cooperation of the lifting unit and the moving unit, the spraying angle and height of the spray gun are adjusted in real time, and the waste and forging oxide scale remaining on the surface of the mold after forging are efficiently cleaned, which effectively reduces the friction and adhesion of the mold surface, reduces the wear rate of the mold, and significantly extends the service life of the mold.

[0035] Through the lifting unit, the moving unit and the rotating position of the spray gun baffle 510, the device can easily adjust the angle and height of the nozzle 509 to achieve flexible adjustment of the lubricant spray path; combined with the precise adjustment of the lubricant delivery pressure control, the distribution of the lubricant flow is further improved, and the problem that traditional lubrication methods are difficult to fully cover all parts of the mold is effectively solved. This design ensures that the lubricant can be evenly distributed on the mold surface, effectively avoiding local over-lubrication or insufficient lubrication. Uniform and reasonable lubrication not only significantly reduces oxidation, cracks and other defects on the forging surface, but also improves the surface quality and overall mechanical properties of the forging.

[0036] This device can also quickly meet the lubrication needs of different forgings through flexible adjustment of the spray gun and precise control of the spray flow rate, greatly shorten the lubrication parameter adjustment time, and provide strong support for efficient forging operations.

[0037] The device also effectively optimizes the usage of lubricating fluid through the partition design of the oil tank, the application of the filter and the adjustable function of the nozzle 509, thereby avoiding waste caused by excessive spraying. In addition, the lubricating fluid recovery and filtration system can realize the recycling of lubricating fluid and reduce resource waste.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
