Description

Technical Field

[0001] The utility model relates to the technical field of final forging dies, in particular to a final forging die structure for high-hardness shaft forgings. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. Forging can apply pressure to the metal blank to cause it to deform plastically and change its mechanical properties. Forging can eliminate the looseness and holes in the metal and improve the mechanical properties of the forging. Final forging is one of the important steps in the production of high-hardness shaft forgings.

[0003] For example, the patent document with the announcement number CN 201889385 U discloses a die structure for die forgings. A final forging die structure for stainless steel die forgings includes a final forging die and a trimming die. The final forging has an upper and lower inclined draft angle and a joint surface formed by the upper and lower draft angles. The flash grooves of the upper and lower die parting surfaces of the final forging die are offset upward or downward toward the joint surface of the draft angle of the final forging. After the offset, the contour line length of the cavity on the side where the cavity depth becomes shallower is shorter than that on the other side. The contour line length refers to the length of the cavity in two orthogonal directions and the total contour line perimeter length. The contour line shape and size of the lower die of the trimming die are the contour line shape and size of the cavity on the side where the cavity depth becomes deeper after the offset of the final forging die. Without adding any processes or materials, and only adopting the technical requirements of the present invention in the die design, the fine processing of the forging process is achieved and energy is saved.

[0004] However, when this structure is used in the final forging die of high-hardness shaft forgings, it is impossible to perform rapid positioning and docking operations with the die, the punching pressure on the top of the forging cannot be synchronously adapted to the damping protection operation, and the final forging effect of the die on the high-hardness shaft forgings cannot be better controlled. At the same time, the equipment often adopts a fixed structure design, which cannot perform uniform final forging cooling and demolding operations of high-hardness shaft forgings, and cannot meet daily use needs. Therefore, it is urgent to design a final forging die structure for high-hardness shaft forgings to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a final forging die structure for high-hardness shaft forgings, so as to solve the problem proposed in the above background technology that when the existing structure is used in the final forging die of high-hardness shaft forgings, it is impossible to perform a rapid positioning and docking operation with the die, the punching pressure on the top of the forging cannot be synchronously adapted to the damping protection operation, and the final forging effect of the die on the high-hardness shaft forgings cannot be better controlled.

[0009] Preferably, a shrinkage groove is provided on the inner wall of the limiting ring seat, and a damping ring airbag is provided inside the shrinkage groove.

[0010] Preferably, a thread groove is provided on the inner wall of the lifting seat, and a sealing gasket is provided on the inner bottom wall of the thread groove.

[0011] Preferably, the bottom end of the lifting seat is fixedly connected to a limiting slide, and limiting balls are provided on the four sides of the limiting slide.

[0012] Preferably, ventilation ring grooves are evenly opened on the inner wall of the cooling sleeve, and filter cores are arranged on both sides of the inner wall of the ventilation ring groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The final forging die structure of the high-hardness shaft forgings can achieve more stable final forging die forging production operation of the high-hardness shaft forgings by means of the provided cooling sleeve, lifting seat, limiting ring seat, lifting sleeve, lifting airbag, top bracket, shrinkage groove, damping ring airbag, thread groove, sealing gasket, limiting slide and limiting ball. In actual use, the staff can screw the bottom of the final forging die of the high-hardness shaft forgings to the thread groove of the lifting seat and seal and fix it with the sealing gasket. At this time, the final forging equipment can be controlled to perform the forging operation on the top of the final forging die. , punch the forging into the interior of the die to complete the final forging operation. At this time, the bottom of the lifting seat inside the cooling sleeve can be limited and contracted downward by the lifting airbag and the top bracket inside the lifting sleeve, and the damping ring airbag at the shrinkage groove on the inner wall of the limiting ring seat can limit the lifting seat and the side of the final forging die. The limiting slide at the bottom of the lifting seat performs a damping sliding operation through the limiting balls on the four sides of the side, thereby ensuring that the lifting seat as a whole obtains a more stable buffer docking operation, thereby improving the forging effect of the final forging die, and reflecting the practicality of the equipment design.

[0015] The final forging die structure of the high-hardness shaft forgings further improves the overall use effect of the equipment by setting a cooling sleeve, a first air inlet unit, a second air inlet unit, a lifting seat, an air outlet base, an air outlet mesh groove, a ventilation ring groove and a filter element. In daily use, after the final forging die on the surface of the lifting seat completes the final forging operation, the lifting airbag and the top bracket are controlled to completely retract them into the interior of the cooling sleeve. At this time, the first air inlet unit and the second air inlet unit on both sides of the cooling sleeve are started, and then the ventilation ring groove and the filter element on the inner wall of the cooling sleeve are coordinated to perform a rapid cooling treatment operation on the side of the final forging die. Finally, the hot air flow is discharged centrally from the air outlet mesh groove of the air outlet base at the bottom of the lifting sleeve, thereby ensuring that the forgings inside the final forging die are efficiently cooled and demolded, meeting the needs of continuous production, and reflecting the comprehensiveness of the equipment design.
