Abstract
An internal spline made of the difficultly processed materials such as high-strength steel is the structure widely applied in a transmission system in a high-tech field such as aviation, aerospace, automobile making, high-grade numerical control equipment, and the like. The slotting process which is universally applied to the traditional production has the problems of serious tool wear, difficultly ensured tolerance of form and position, difficulty in processing and cleaning burr and low production yield. The invention relates to an electrical discharge machining method fit for the internal spline structure of difficulty processed materials. Aiming at the internal spline made of the difficultly processed materials such as high-strength steel which is widely applied in the transmission system in the high-tech field such as aviation, aerospace, automobile making, high-grade numerical control equipment, and the like, the invention provides a novel electrical discharge machining method fit for the internal spline structure of the difficultly processed materials according to the process characteristic of the electrical discharge machining so as to realize low cost, high efficiency and high processing precision of the internal spline structure of the difficultly processed materials.
Description
1, technical field
The present invention relates to a kind of Electric Discharge Machining method that is applicable to difficult-to-machine material internal spline structure.At the internal spline structure of making by difficult-to-machine materials such as high strength steels in the high-tech areas such as Aeronautics and Astronautics, automobile making, high-grade numerical control equipment, operational characteristic according to Electric Discharge Machining, propose a kind of novel difficult-to-machine material Electric Discharge Machining method, realized low cost, high efficiency, the high accuracy processing of difficult-to-machine material internal spline structure.
The present invention is mainly used in the Electric Discharge Machining of difficult-to-machine material internal spline structure in the high-tech areas such as Aeronautics and Astronautics, automobile making, high-grade numerical control equipment.
2, background technology
Internal spline is a class formation of extensive use in the transmission system, has broad application prospects in high-tech areas such as Aeronautics and Astronautics, automobile making, high-grade numerical control equipment.
In recent years, along with high-tech areas such as Aeronautics and Astronautics, automobile making, high-grade numerical control equipment for improving constantly that transmission system function of use and physical dimension require, the material of transmission system key components and parts such as inside spline wheel gear etc., form accuracy, positional precision, surface roughness etc. require also strict further.In high-tech area transmission systems such as Aeronautics and Astronautics, automobile making, high-grade numerical control equipment, inside spline wheel gear adopts difficult-to-machine materials such as high strength steel more, more generally adopt slotting processing in producing at present, have that tool wear is serious, form and position tolerance is difficult to guarantee, machined burrs cleaning difficulty, problem that product percent of pass is low.
Galvano-cautery phenomenon when the principle of Electric Discharge Machining is based on pulse feature spark discharge between tool-electrode and the workpiece is come the ablation excess metal, to reach the design processing request of size, shape and surface quality, have precision height, suitable characteristics of processing special or complicated shape and hard-cutting material to part.Electric Discharge Machining provides a kind of effective solution for the internal spline structure processing of difficult-to-machine material.
3, summary of the invention
For the internal spline structure of being made by difficult-to-machine materials such as high strength steels, the slotting difficult processing that more generally adopts in producing at present is with the form and position tolerance of assurance internal spline structure, and tool wear is serious, product percent of pass is low.Low cost, high efficiency, high accuracy that the present invention proposes to adopt the Electric Discharge Machining method to realize difficult-to-machine material internal spline structure are processed.
Technology contents of the present invention is a kind of Electric Discharge Machining method that is applicable to difficult-to-machine material internal spline structure.
4, description of drawings
Accompanying drawing: the Electric Discharge Machining schematic flow sheet of difficult-to-machine material internal spline structure;
5, the specific embodiment
According to the process characteristic of Electric Discharge Machining, be applicable to that the Electric Discharge Machining method of difficult-to-machine material internal spline structure comprises in proper order: 1. select the location benchmark according to internal spline structural design drawing; 2. determine the Electric Discharge Machining operational characteristic of tool-electrode and internal spline material by engineer testing; 3. prepare according to internal spline structure and engineer testing consequence devised that electric spark is thick, the finisher electrode; 4. design prepares or selects for use special fixture to carry out clamping, correction, fixing; 5. select suitable electric machining parameter and liquid-charging type to carry out Electric Discharge Machining according to engineer testing; 6. look tool electrode loss situation dressing tool electrode.
Adopt Electric Discharge Machining method difficult processing rapidoprint internal spline structure, problem such as can avoid effectively that tool wear in the traditional slotting processing is serious, form and position tolerance is difficult to guarantee, machined burrs cleaning difficulty, product percent of pass are low has remarkable advantages at aspects such as precision guarantee, working (machining) efficiency, cost control, qualification rate assurances.
