An upper die base and a lower die base are respectively installed on the support plates. The upper die base is fixedly connected to an upper die, and the lower die base is fixedly connected to a lower die;
[0006] A heat preservation shell is sleeved outside the lower die, and a heat preservation box is arranged inside the heat preservation shell. The heat preservation box is fixedly connected to the lower die base. A fixing seat is further arranged inside the heat preservation box, a push plate seat is arranged in the middle of the fixing seat, and a cushion plate is arranged on the push plate seat.
[0007] In a further embodiment, the bottom of the heat preservation box is of a hollow structure and is fixedly connected to the lower die base.
[0008] In a further embodiment, a plurality of through holes are arranged in the middle of the push plate seat.

[0010] In a further embodiment, the forming assembly includes a forming die head, the forming die head is fixedly connected to the upper die base through a push rod, and a shock-absorbing spring is sleeved outside the push rod at the end of the forming die head close to the upper support plate.
[0011] In a further embodiment, a plurality of air-dispersing strips are arranged on the surface of the heat preservation box.
[0012] In a further embodiment, a number of fine holes are formed on the surface of the push plate seat, and the fine holes are communicated with the through holes.
[0013] In a further embodiment, a plurality of the forming dies are provided and fixed by a limiting frame. Beneficial effects
[0014] Put the forging raw material into the lower die, and the upper die base pushes the upper die to combine with the lower die for forging, and the forging raw material is forged and formed.
