Equipment principle of vohcl-vc400dhf-high speed intelligent EDM surfacing repair machine

The technology of electric spark deposition is to release the high energy stored in the power supply at the instant of high frequency between the metal electrode and the metal base metal, and form a channel through the air ionization between the electrode material and the base metal, so that the surface of the base metal will produce the instant high temperature and high pressure micro area. At the same time, the ionic electrode material will melt into the base metal under the action of the micro electric field, forming a metallurgical combination. Because the process is an instantaneous high temperature cooling process, not only martensite is formed on the metal surface due to quenching, but also ultrafine austenite structure is formed in the narrow over deposition area. EDM is not a welding, spraying or element infiltration process. In a word, it is a process between them.

Features of vohcl-vc400dhf intelligent high speed EDM surfacing repair machine:
1. Vanchi technology is leading: it adopts ultra-precision high-performance processor, dual terminal flow control technology, energy recovery and chopping technology, with higher speed, ultra-precision output control, intelligent digital one button start-up regulation, simpler operation, higher efficiency and more stable performance.

2. High welding repair strength: the single output energy can reach tens of joules, so the welding material can be completely melted to the matrix, forming a metallurgical combination, producing a very strong binding force.

3. High welding repair precision: the welding repair precision can reach micron level, and can be directly processed by turning, milling, grinding, drilling, etc., without air hole, sand hole, small color difference or color difference. Even the machining surface without allowance can be welded and repaired without deformation, undercut or burn.

4. No annealing and deformation: it can output 500 energy beams within 1 second, forming the repeated process of energy beam input and recovery, so that the matrix will not have too much temperature rise, so there is no deformation, undercut and residual stress, no local annealing.

5. One high-end strategic machine is multi-purpose: it is suitable for customers with high quality requirements. It can weld defects of metal workpieces, strengthen the surface of metal workpieces and molds, and cover a wide range of weld repairs (such as ferrous metals: nodular iron, gray iron, steel, etc.; non-ferrous metals: aluminum, copper, etc.). Especially for non-ferrous metals, the efficiency of welding repair is improved obviously, and the welding repair strength is high.

6. Powerful storage capabilities:
(1) fixed storage function: the user can quickly retrieve the best parameters of cast steel, cast iron, copper, aluminum, magnesium, zinc and coating stored in the machine when leaving the factory; it has high intelligence, simple operation, no need for professional knowledge engineers (women workers can operate), and can learn to use them immediately in a few minutes.

(2) multi group parameter storage: users can also store their frequently used parameters to facilitate quick access.

7. Excellent welding repair effect for copper, aluminum, magnesium, zinc, nodular iron, gray iron and steel: due to the instantaneous high energy output, it effectively solves the welding repair of high conductivity metal such as copper aluminum metal, and overcomes the shortcomings of weak combination of ordinary EDM surfacing.

8. Environmental protection: no pollution during operation.

9. Usability: anyone is easy to use (female workers can operate), no special welder's operation certificate is required, and hardfacing can also be carried out where it is difficult to weld.

10. Economy: repair immediately on site, improve production efficiency, save cost, high cost performance, and worry free in the later stage.

11. Wide application of welding materials: due to different control methods of vohcl-vc400dhf, high output energy and fine control, the applicability of welding materials is wide. In addition to the special welding materials required by the conventional EDM surfacing repair machine, most of the straight welding materials with the diameter of 0.3-4.0mm used by other welding machines are applicable, and the ordinary welding electrodes can also be used after the coating is removed.

Die surface coating strengthening function: the superhard alloy is quickly coated on the die surface and penetrated into the die structure in a short time. After coating, the wear resistance, corrosion resistance, impact resistance, demoulding resistance and heat resistance of the die can be increased.

Application scope of vohcl vc400dhf intelligent high speed EDM surfacing repair machine:

1. Suitable for impact resistant mould (die casting mould, die casting mould, forging mould, plastic mould, stamping mould, etc. extend 3 times of service life)

2. Suitable for high heat resistant surface (such as die feed port, die core, etc. to extend 3 times of service life)

3. Cutting tools and cutting tools (milling cutter, turning tool, cutter, drill, etc. extend 5 times of service life)

4. It is applicable to the covering of clamps and collets, and increases the wear-resistant function.

5. The thickness and thickness of the coating can be adjusted arbitrarily, and the standard thickness is 0.01-0.1mm.

The coating strengthening function of vc400dhf intelligent high-speed EDM surfacing repair machine can be repeatedly and repeatedly strengthened to improve the service life of the mold and enhance the demoulding performance; the coating thickness on the surface of the mold can be adjusted from a few microns to a few millimetres according to the needs; during the coating process of the mold, the substrate does not need to be preheated, the substrate does not heat up, the metallographic structure near the coating area does not change, and there is no stress collection Middle phenomenon. That is to say, the heat energy required in the coating process of each unit is an intelligent output of the equipment. The whole coating process matrix and the surrounding area are always in the normal temperature state, without thermal deformation and cracks.

In the whole process of die coating, the parts are always in a constant temperature state, so the defects in the traditional welding repair or surface coating process have to be avoided, and the problem of die drawing and sticking has been solved. After being coated, the parts can be used without treatment, and can be repeatedly covered.

Vc400dhf - intelligent high-speed EDM surfacing repair machine is especially outstanding in the application of die-casting mould coating. When the die-casting mould is stuck and glued in the use process, the waste, oil, mold release agent and other foreign matters adhered on the surface of the mould shall be simply cleaned first, and then the gluing and gluing parts shall be covered with the equipment. After being covered, no treatment is required, and the die-casting mould can be directly In the process of on-line production, the coated part can be free of mould and material sticking for a long time. If the phenomenon of mould and material sticking occurs after a long time of use, repeat the above steps. The equipment can cover the mould for unlimited times, so as to improve the service life of the mould and enhance the demoulding performance.
