Description

Technical Field

[0001] The present invention belongs to the technical field of backward extrusion dies, and specifically refers to a warm forging backward extrusion die device. Background Art

[0002] In the field of metal pressure processing technology, the backward extrusion die is an important type of die, specifically referring to an extrusion die in which the flow direction of the metal is opposite to the movement direction of the punch during extrusion forming. This die structure has been widely used in warm forging processes, especially in the manufacturing process of forgings that require complex shapes and high precision.

[0003] However, in the current warm forging process, especially when upsetting stock is placed into the backward extrusion die cavity for processing, the problem of material shoveling often occurs. The material shoveling phenomenon refers to the local metal accumulation or tearing of the blank during extrusion in the die due to uneven material flow, improper die clearance setting, etc. during the die closing process, resulting in irregular metal protrusions or burrs. This not only seriously affects the surface quality and dimensional accuracy of the forgings, but also may cause damage to the die and a reduction in processing efficiency. Summary of the Invention

[0016] (2) As an inert carrier gas, nitrogen can inhibit the oxidation and decomposition of the lubricant, enhance the dispersion uniformity of the atomized droplets at the same time, and reduce the risk of local lubrication failure.

[0017] (3) With the setting of the forging mechanism, the atomized lubricant can form a continuous lubricating film on the inner wall of the mold cavity, reducing the direct contact between the blank and the mold, reducing the shear stress during the extrusion process, thereby inhibiting the shoveling phenomenon caused by material adhesion. Nitrogen-assisted spraying can avoid the accumulation of lubricant generated by the traditional coating method and prevent local sticking of the mold caused by uneven distribution of the lubricant.

[0018] (4) With the setting of the pretreatment component, the heated blank is protected by argon, reducing the risk of high-temperature oxidation and decarburization.

[0019] (5) With the setting of the oxide scale cleaning component, the high-temperature oxide scale can be removed, preventing defects from forming on the surface of the forged part being pressed in, and extending the service life of the mold at the same time.

[0020] (6) With the setting of the cleaning component, the exfoliated oxide scale is cleaned and pushed to the leakage hole and then falls into the collection bucket, preventing the oxide scale from entering the mold cavity and affecting the forging effect.

[0021] (7) With the setting of the air outlet component, the excess gas in the compression cavity can flow out by pushing open the sealing ball. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] During specific use, start the booster pump 23, and convey the lubricant in the lubricant storage tank 22 to the atomizing nozzle 25 through the first output pipe 24. After being atomized by the atomizing nozzle 25, it enters the mold cavity 13. Open the first electronic valve 28 and the first pressure reducing valve 29. The nitrogen gas compressed in the nitrogen storage tank 26 enters the compression cavity 20 through the second output pipe 27, then enters the ventilation pipe 16 through the round hole 19, and finally sprays out through the first air outlet hole 17 and the pupil on the side wall of 15. The atomized lubricant in the mold cavity 13 is sprayed on the inner wall of the mold cavity 13 to form a lubricating film covering the inner wall surface of the mold cavity 13, reducing the friction coefficient. As an inert carrier gas, nitrogen can inhibit the oxidation and decomposition of the lubricant, enhance the dispersion uniformity of the atomized droplets at the same time, and reduce the risk of local lubrication failure. The atomized lubricant can form a continuous lubricating film on the inner wall of the mold cavity 13, reducing the direct contact between the blank and the mold, and reducing the shear stress during the extrusion process, thereby inhibiting the shoveling phenomenon caused by material adhesion. Nitrogen-assisted spraying can avoid the accumulation of lubricant generated by traditional coating methods and prevent local sticking of the mold caused by uneven distribution of the lubricant. Place the heated cylindrical blank on the turntable 48. The output end of the motor 43 rotates to drive the first bevel gear 44 to rotate. The first bevel gear 44 rotates to drive the second bevel gear 45 to rotate. The second bevel gear 45 rotates to drive the gas transmission pipe 46 to rotate. The gas transmission pipe 46 rotates to drive the turntable 48 to rotate. The turntable 48 rotates to drive the cylindrical blank to rotate. At the same time, open the second electronic valve 52 and the second pressure reducing valve 53. The argon gas compressed in the argon storage tank 50 enters the gas transmission pipe 46 through the third output pipe 51, then enters the turntable 48, and finally sprays out through the second air outlet hole 49. Under the protection of argon gas, the risks of high-temperature oxidation and decarburization are reduced. The output end of the first cylinder 39 moves downward to drive the U-shaped frame 59 to move downward. The U-shaped frame 59 moves downward to clean the surface of the heated cylindrical blank with the wire brush 40 to remove the surface oxide scale. After the cleaning is completed, while the output end of the first cylinder 39 resets, the output end of the third cylinder 54 moves, thereby driving the second push plate 55 to move. The second push plate 55 moves to drive the cleaning brush 56 to move, cleaning and pushing the peeled oxide scale to the leakage hole 57 and then falling into the collection bucket 58. After the output end of the third cylinder 54 resets, the output end of the second cylinder 41 moves to drive the second push plate 55 to move, thereby pushing the cylindrical blank to move to the top plate 15. After the output end of the second cylinder 41 resets, the output end of the hydraulic cylinder 8 moves downward to drive the reverse extrusion punch 9 to move downward, extruding the cylindrical blank into the mold cavity 13. At this time, the top plate 15 moves to the upper end of the limit plate 14. At this time, the atomized lubricant enters the channel 65 through the through hole on the side wall of the top plate 15. The first spring 21 is compressed, and the excess gas in the compression cavity 20 flows out by pushing open the sealing ball 30. After the output section of the hydraulic cylinder 8 resets, the top plate 15 resets under the action of the first spring 21, and the atomized lubricant and nitrogen gas are sprayed on the inner wall of the mold cavity 13 again. The above is the overall working process of the present invention, and this step can be repeated during the next use.
