Example Embodiment
[0017] Embodiment 1: A mold for processing a special-shaped counterweight block with a gas turbine radian of R430 in this embodiment is composed of a concave mold 1 and a punch 2, and the concave mold 1 has an radian of R 1 For R431, punch 2 radians R 2 It is R429; the female die 1 has a groove 3 on the arc surface along the length direction, and the punch 2 has a groove 4 on the arc surface corresponding to the groove 3 along the length direction, so The radius R of the groove 3 described 3 and the radius R of groove 4 4 equal, and groove 3 and groove 4 cooperate with each other.
[0018] In this embodiment, a mold for processing a special-shaped counterweight block with a gas turbine radian of R430 sets the radian of the concave mold to R431 and the radian of the punch to R429, so that the combination of the concave mold and the punch increases compared with the existing method. 1.5 of the anti-machining springback allowance, after the springback, just make the special-sh...
Example Embodiment
[0019] Specific embodiment 2: A method of processing R430 special-shaped counterweight blocks with a mold for processing gas turbine radians with special-shaped counterweight blocks of R430 according to the present embodiment is characterized in that the method is carried out according to the following steps:
[0020] 1. The material will be turned into a cylindrical bar, and the radius of the cylindrical bar is R 5 , and then heated to a temperature of 290-350 °C with an oxyacetylene flame;
[0021] 2. Put the heated bar in step 1 into the groove 4 of the mold, the concave mold 1 goes down to match the groove 3 and the groove (4), and then press the concave mold 1 and the punch 2 with a vise There is no gap, and the pressure is maintained for 5min to 10min to obtain a special-shaped counterweight with an arc of R430. The radius of the groove 3 is R. 3 and the radius R of groove 4 4 equal to the radius R of the cylindrical bar in which the 5 and the radius R of groove 3 3 ...
Example Embodiment
[0023] Embodiment 3: The difference between this embodiment and Embodiment 2 is that in step 1, oxyacetylene flame is used to heat to a temperature of 310-330°C, and other steps and parameters are the same as those of Embodiment 2.
