Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
[0028] The embodiment relates to a stamping shell material heat shaping device, referring to Figures 1-4, including: an upper die assembly 100, a heating assembly 200, a lower die assembly 300 and a feeding assembly 400. Wherein the bottom surface of the upper die assembly 100 is provided with a first arc surface 141; the heating assembly 200 is arranged in the upper die assembly 100 and close to one side of the first arc surface 141, and the heating assembly 200 is used for heat shaping the shell material 800 to be shaped. By using the heating assembly 200 to heat shape the shell material 800 to be shaped, the shell material 800 to be shaped will be plastically deformed at high temperature, which can greatly reduce the internal stress of the shell material 800 to be shaped during processing, especially for the high-hardness metal shell material 800, thereby reducing the risk of deformation and plastic fracture and helping to improve the shaping effect of the shell material 800 to be shaped. The lower die assembly 300 is assembled on the lower side of the upper die assembly 100; the feeding assembly 400 is assembled on the lower side of the lower die assembly 300, and the feeding assembly 400 is used to drive the lower die assembly 300 to reciprocate relative to the upper die assembly 100; the top surface of the lower die assembly 300 is provided with a second arc surface 321; the first arc surface 141 and the second arc surface 321 protrude in the same direction. In this embodiment, the bottom surface of the upper die assembly 100 is provided with the first arc surface 141, the top surface of the lower die assembly 300 is provided with the second arc surface 321, and the first arc surface 141 and the second arc surface 321 protrude in the same direction to make the shell material 800 to be shaped arch upward or downward first, and after shaping, due to the internal stress of the shell material 800 itself, the shell material 800 around and the middle part of the shell material 800 can restore to a flat state, which ensures the flatness of the surface of the shell material 800, avoids the deformed shell material 800 to rebound to the reverse arch deformation state, ensures the good shaping effect and the high shaping efficiency. At the same time, the feeding assembly 400 is assembled on the lower side of the lower die assembly 300, and the feeding assembly 400 is used to drive the lower die assembly 300 to reciprocate relative to the upper die assembly 100, so the operator only needs to place the shell material 800 to be shaped on the second arc surface 321, and then drives the feeding assembly 400 to drive the lower die assembly 300 to move towards the direction directly below the upper die assembly 100, so that the operator can avoid the high-temperature operation area, i.e. the area directly below the upper die assembly 100, during the process of placing the shell material 800 to be shaped and taking out the shaped shell material 800, so as to avoid being scalded, which ensures the operation safety of the operator and the high overall safety factor.
[0029] With reference to Figures 2-4When the shell material 800 to be shaped is placed on the second arc surface 321, the feeding assembly 400 drives the lower die assembly 300 to move the shell material 800 to be shaped to the position directly below the upper die assembly 100, and the upper die assembly 100 is pressed downward to close the lower die assembly 300 to perform stamping shaping on the shell material 800 to be shaped. Specifically, when the shell material 800 to be shaped needs to be hot shaped, the shell material 800 to be shaped is placed on the second arc surface 321, the feeding assembly 400 drives the lower die assembly 300 to move toward the position directly below the upper die assembly 100, until the lower die assembly 300 is in the position directly below the upper die assembly 100, at this time, the upper die assembly 100 is pressed downward, the upper die assembly 100 is closed with the lower die assembly 300 to perform stamping shaping on the shell material 800 to be shaped. When the stamping shaping of the shell material 800 is completed, the feeding assembly 400 drives the lower die assembly 300 to move away from the position directly below the upper die assembly 100, so that the lower die assembly 300 is away from the high-temperature working area, and then the next shell material 800 to be shaped is placed. The overall shaping efficiency is high, convenient and fast.

The first arc surface 141 and the second arc surface 321 are both arranged to be upwardly convex, after the upper die assembly 100, the heating assembly 200 and the lower die assembly 300 shape the shell material 800 to be shaped, the middle part of the shell material 800 is upwardly arched, the periphery thereof is downwardly arched, and then the shell material 800 as a whole will return to the flat state due to the internal stress of the shell material 800 itself, and the shell material 800 to be shaped is pre-shaped to be in the reverse arch state, which can also avoid rebounding of the shaped shell material 800. In some embodiments, the first arc surface 141 and the second arc surface 321 can also both be downwardly convex.

The guide rail 440 plays a guiding and limiting role and ensures that the movable plate 430 moves towards or away from the position directly below the upper die assembly 100. Under the pushing or pulling action of the pusher 420, the movable plate 430 drives the lower die assembly 300 to reciprocate along the guide rail 440 relative to the upper die assembly 100. Referring to Figure 1 and Figure 2 When the operator needs to place the shell material 800 to be shaped, the pusher 420 is started, and the pusher 420 is reset to the initial state, that is, the telescopic end of the pusher 420 is retracted. At this time, under the pulling action of the pusher 420, the movable plate 430 drives the lower die assembly 300 to move along the guide rail 440 away from the position directly below the upper die assembly 100, so that the lower die assembly 300 moves away from the high-temperature operation area, avoiding the operator from being scalded in the process of taking down the shaped shell material 800, and ensuring the safety of the operator. When the next shell material 800 to be shaped needs to be shaped, the pusher 420 is started, and the telescopic end of the pusher 420 is expanded. Under the pushing action of the pusher 420, the movable plate 430 drives the lower die assembly 300 to move along the guide rail 440 towards the position directly below the upper die assembly 100, and the pusher 420 is turned off when the lower die assembly 300 moves to the position directly below the upper die assembly 100. In the process of taking down the shaped shell material 800 and placing the next shell material 800 to be shaped, the operator does not need to directly contact the high-temperature operation area, greatly protecting the safety of the operator and improving the safety factor of the stamping shell hot shaping device.
