The upper main body cavity 11 and the lower main body cavity 21 are mirror images of each other, and the upper flange cavity 12 and the lower flange cavity 22 are rotationally symmetrical.

[0033] Inserts 3 are detachably installed in the upper flange cavity 12 and the lower flange cavity 22. The two inserts 3 are arranged in opposite positions. One end of each insert 3 is provided with a sloping pressure surface 311. There are multiple inserts 3, and the sloping pressure surface 311 on different inserts 3 is set with different inclination angles.

[0034] By setting inserts 3 with different tilt angles, when the valve body flange angle needs to be adjusted and processed under different working conditions, different combinations of inserts 3 on the upper and lower molds 2 can be replaced to quickly and conveniently process the flange, change the flange angle, save time and effort, and improve efficiency and product applicability.

[0035] Preferred, refer to Figure 6 The insert 3 includes a post 32, a pressure block 31, and a limiting block 33.

[0036] The valve body blank is squeezed by the inclined pressing surface 311 of the high-strength insert 3 to shape the flange. The clearance groove 312 is used to fix the flange to avoid the blank being damaged or sliding during the processing, thus ensuring the processing accuracy. The limit block 33 is used to fix the insert 3 to prevent the insert 3 from falling off.

[0037] Preferred, refer to Figure 7 The upper flange cavity 12 includes a first inclined groove 121 and a first countersunk hole 122 arranged side by side. The first countersunk hole 122 is located on the right side inside the upper flange cavity 12.

[0042] Preferred, refer to Figure 3 and Figure 4 The upper main body cavity 11 and the lower main body cavity 21 have the same shape, both being T-shaped. Both the upper main body cavity 11 and the lower main body cavity 21 have punch cavities 4 on both sides, and punches 5 are installed in the punch cavities 4. The punches 5 are used to stamp and process the valve body blank, so that the valve body blank is shaped.
