Embodiment Construction
[0031] Below in conjunction with embodiment the present invention is described in further detail:
[0032] Such as figure 1 , 2 As shown, the workpiece has a curved shape, deep cavity, variable cross section, high material hardness and high roughness requirements.
[0033] Such as Figure 5 As shown, the variable cross-section curved cavity processing machine tool is based on the existing three-axis CNC EDM machine tool, which is composed of the machine tool host, power supply, numerical control system and working fluid tank. Pillow X, Y-axis moving parts and Z-axis parts, the machine tool adopts the bull head C-shaped structure, controlled by the numerical control system, as the supporting part of the machine tool, the bed adopts a box-shaped structure, which can obtain high supporting rigidity, and the machine tool is set on the bed Table and oil tank, ram X, Y axis moving parts are all placed on the back of the bed, which is conducive to improving the movement rigidity a...

The invention discloses a process manufacture method of a variable section bend cavity. At first, the cavity is roughly milled; through holes are drilled at the two ends of the opening of a bend body; the milling process is achieved from the two ends along the drilling direction; 3-5mm of the process redundancy is preserved by an electric spark at the position which can be processed; after that, the process forming is achieved by the electric spark; a hollow electrode with the same shape of the bend cavity is designed and manufactured; the electrodes have three types: a rough electrode, a half precise electrode and a precise electrode; the process forming is achieved by the rough electrode electric spark at first, the half precise electrode electric spark is then used for process forming and the precise forming is finally achieved by the precise electrode electric spark; by adopting the processing and manufacture method of the invention, the processing precision is high and the efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing technology, and in particular relates to a method for processing and manufacturing a curved cavity with variable cross-section. Background technique [0002] At present, for the processing of the variable cross-section curved cavity with high mechanical performance requirements, foreign countries often use precision casting molding, domestic precision casting technology is not yet perfect, generally adopt conventional processing methods, that is, the combination of milling processing and fitter manual processing molding The method of processing, the processing technology surface error is large, the processing cycle is very long, and the processing efficiency is low. [0003] EDM manufacturing technology is a special manufacturing technology, and the processing method generally adopts one-way linear feed. The shafts generally used for rotary feed in China have a very small bearing...
