Embodiment 1

[0023] This embodiment provides a K465 alloy isothermal forging die processing method, which is characterized in that: the K465 alloy isothermal forging die processing method adopts an electrical machining method;

[0024] The first is billet casting to control the machining allowance; then the riser is cut off by wire cutting, the six sides are ground by vertical mill, and all the profiles are processed by the profile electrodes and the electrodes of each hole; finally, the profile is detected by three coordinates.

[0025] In order to ensure mold precision and processing efficiency, profile electrodes are divided into 2 pieces: rough punching and precision punching, and the discharge gap is cut to 0.6mm and 0.2mm on each side respectively. The main process is as follows:

[0026] 1) Cutting material: 2 pieces of K403 castings;

[0027] 2) Vertical mill: Guarantee the requirements of the drawing on all sides, and the upper and lower sides can be flat to "∥⊥"≯0.02;

Abstract

An isothermal forging die processing method for K465 alloy adopts the electro-processing method. Firstly, blanks are cast to control the processing allowance; secondly, dead heads are cut through linear cutting, six surfaces are formed through grinding with a vertical mill, and all the profiles are processed through profile electrodes and perforated electrodes; lastly, the profiles are detected through a coordinate measuring machine. To guarantee the die precision and the processing efficiency, the profile electrodes include a rough finish electrode and a final finish electrode, and the discharging gaps are 0.6mm per edge and 0.2mm per edge respectively. Compared with the conventional forging method, the isothermal forging die processing method has the following advantages: forge pieces with complicated shapes and high precision can be manufactured through forging, so that raw materials are saved, machining is greatly reduced, and the cost is lowered; the forging load is smaller, so that the equipment tonnage is greatly reduced; the single-pass large deformation technique can be realized, so as to achieve more precise organizational structures; a die cavity is easily filled with the blanks, so that the die wear degree is reduced, and the isothermal forge pieces are normally free from residual stress.

Description

technical field [0001] The invention relates to the field of forging die processing methods, in particular to a K465 alloy isothermal forging die processing method. Background technique [0002] Titanium and titanium alloys are widely used because of their excellent comprehensive properties such as high specific strength, especially in the aviation industry. Because titanium alloy has high deformation resistance and low plasticity at room temperature, it is difficult to deform and process. Isothermal forging can produce titanium alloy fine forgings with uniform microstructure under lower forging load. Isothermal forging is to heat the die to the same temperature as the workpiece during the forging process. Isothermal forging has many advantages that conventional forging cannot match, and ordinary machining cannot be completed. Contents of the invention [0003] The purpose of the present invention is to overcome the problem that ordinary mechanical processing cannot be c...
