Embodiment 1

[0030] Step 1: Forging drawing design

[0031] The part is a ring, with an extra allowance of 5mm for the outer diameter and 5mm for the inner diameter. The forging slope of the outer wall is designed to be 5° according to the height of the ring, and the slope of the outer wall is from one end to the other end of the height of the ring; The height dimension of the ring is designed to be 10°, the slope of the inner wall is from both ends of the height of the ring to the middle position, and the thickness of the middle skin is 10mm; 5mm is added to one side in the height direction. figure 1 It is the forging drawing obtained after adding allowance to the part drawing.

[0032] Step 2: tire mold design

[0033] The tire mold mold includes a jacket, an upper punch and a lower punch. Jacket: The height of the jacket is the same as that of the forging, the inner wall of the jacket is the same size as the outer wall of the forging, and the slope is the same; the diameter of the tai...

Abstract

The invention discloses a tire mold forging method for GH4163 annular forgings. In the method, the forging logarithmic strain is determined as ε=0.4-0.7, the length of the blank is L=1.5H-2H, and the diameter D of the blank satisfies the relational formula: L=4V / ((3.14D 2 )*1.05), and satisfy L / D<2. Using the method of the present invention to forge GH4163 alloy ring-shaped forgings improves the surface quality of the forgings, and the deformation of the forgings is uniform, avoiding problems such as cracks, uneven structure and performance, and coarse grains in free forging, and the grain size of the forgings can reach An average grade of 7‑8 ensures the properties of the resulting ring forgings.

Description

technical field [0001] The invention belongs to the technical field of forging, and in particular relates to a method for forging a GH4163 annular forging tire mold and a tire mold mold. Background technique [0002] GH4163 is a high-temperature alloy strengthened by elements such as aluminum, titanium, molybdenum, and cobalt. It has a high degree of alloying and is a hard-to-deform high-temperature alloy. As a typical hard-to-deform superalloy, GH4163 has a high degree of alloying, high deformation resistance, and a narrow deformation temperature range, so it is very difficult to form by hot processing. In particular, the microstructure of forgings is sensitive to deformation process parameters, and abnormal structures formed due to improper control of process parameters often cannot be completely eliminated by subsequent heat treatment. The microstructure has a significant impact on the plasticity, impact toughness, fatigue performance and a series of physical performance...
