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.

Abstract

The invention provides a die machining a gas turbine special-shaped balancing weight with a radian of R430 and a method for machining the special-shaped balancing weight with the die, and relates to the die machining the gas turbine special-shaped balancing weight with the radian of R430 and the method for machining the special-shaped balancing weight with the die. The die and the method solve the problems that a method for machining an arc of an existing gas turbine special-shaped balancing weight is unreasonable in tool design, so the size of the obtained special-shaped balancing weight has errors and waste products are caused. The die comprises a female die and a male die, wherein the radian of the female die is R431, the radian of the male die is R429, the female die and the male die are respectively provided with a groove, and the radius of one groove is equal to and matched with the radius of the other groove. According to the method, supplied materials are firstly heated through oxyacetylene flames and then are placed in the die to be pressed, the waste products caused by machining errors are avoided, shape righting with manual pliers is needless, time and labor are saved, the pass rate of products after machining in bulk is high and can reach 100% at most, and the method is suitable for being used in industrial production and is applied to the mechanical machining field.

Description

technical field [0001] The invention relates to a mold for processing a special-shaped counterweight block whose radian is R430 for a gas turbine and a method for processing the special-shaped counterweight block by using the mold. Background technique [0002] The existing processing method for the arc of the special-shaped counterweight block with a gas turbine arc of R430 (R is 430mm) uses a vise with a die tooling. The processing process is a single cold process, and the mold used is a concave die with an arc of R430.25 ( R is 430.25mm), and the radian of the punch is R429.75 (R is 429.75mm). Put the cylindrical rod into the middle of the laminated film, then put the laminated film into the vise, and pinch it with the vise The die is pressurized until there is no gap between the die and the punch, and the counterweight is obtained. The tooling design of this method is not ideal, and the arc radian of the processed special-shaped counterweight does not meet the requiremen...
