Problems solved by technology
Therefore, when processing large workpieces, due to the need for a larger vacuum chamber, the vacuum chamber needs a longer time to vacuumize to reach the vacuum condition, which reduces production efficiency and increases production costs.
In addition, processing must be carried out in a vacuum chamber, which cannot meet certain processing requirements or bring great inconvenience to processing

Embodiment Construction
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0020] Such as figure 1 As shown, a simple electron beam mold processing machine includes an electron gun, a focusing coil 1 and a deflection coil 2 . One end of the electron gun is provided with an outlet 3 for emitting electrons. The focusing coil 1 and the deflection yoke 2 are sequentially arranged outside the exit 3, that is, the focusing coil 1 is close to the exit 3, and the electrons emitted by the electron gun form an electron beam 4 in a vacuum environment. A vacuum forming mechanism is also included. The vacuum forming mechanism is located on the periphery of the electron gun and drives air to flow to form a preset vacuum degree.
[0021] The vacuum forming mechanism includes an outer shell 5, an inner...

The invention relates to a simple electron beam mold machining machine which comprises an electron gun, a focusing coil and a deflection coil. One end of the electron gun is provided with an outlet for emitting electrons; the focusing coil and the deflection coil are sequentially arranged on the outer side of the outlet and enable electrons emitted by the electron gun to form electron beams in a vacuum environment; and the machine further comprises a vacuum forming mechanism. The vacuum forming mechanism is located on the periphery of the electronic gun and forms a preset vacuum degree by driving air to flow. The simple electron beam mold machining machine has the beneficial effects that compared with an existing electron beam machining device, operation of removing the vacuum chamber andvacuumizing does not need to be carried out in a special vacuum chamber, the machining efficiency is improved, the cost is saved, meanwhile, machining can be carried out anytime and anywhere, and themachining convenience is greatly improved.
Description
technical field [0001] The invention relates to the field of processing equipment, in particular to a simple electron beam mold processing machine. Background technique [0002] Scanning electron beam surface modification technology is a new type of technology that directly scans and modifies metal surfaces in a vacuum environment. The core of this technology is the circular scanning method. The electrons irradiated on the surface of the material quickly convert kinetic energy into heat energy, which makes the surface of the material heat up instantly. Due to the extremely short processing time and large temperature gradient, the temperature change of the substrate below the surface of the material is relatively small. Low, so the surface material rapidly cools down and undergoes a phase change, resulting in a change in the surface properties of the material. [0003] Existing electron beam processing machines must be used in a vacuum state. According to the size and shape ...
