Description

TECHNICAL FIELD

[0001] The utility model relates to alloy cutting technical field, especially to many on -line automatic gas protection light metal and its alloy milling device. BACKGROUND

[0002] In the field of hydrogen storage material production, magnesium-based hydrogen storage material is widely used due to its high hydrogen storage capacity and low cost, and its performance is closely related to the particle size and uniformity of magnesium powder, which usually requires nanoscale to improve the specific surface area and reactivity. At present, the process of magnesium ingot processing into hydrogen storage material mainly relies on the combined process of "milling + refining", and milling as a pre-process directly affects the quality of subsequent refining.

[0003] The existing magnesium ingot processing equipment has technical deficiencies. Traditional equipment is mostly in single independent operation mode, lacks multi-device on-line collaborative transmission and control structure, and is difficult to realize continuous and automatic processing of batch workpieces, resulting in low production efficiency and the need for a large number of manual participation in material replacement and adjustment, etc. The light metal (especially magnesium) has active chemical properties, and in the milling process, high temperature is generated due to high-speed cutting, which is easy to cause oxidation reaction with oxygen in the air, and even may cause combustion. The traditional device often lacks a reliable gas protection system, which cannot effectively isolate air to avoid such risks, and the processing safety cannot be guaranteed.

[0004] The transmission structure design of traditional milling feeding mechanism is not reasonable enough, and problems such as unstable feeding speed and positioning deviation often occur, resulting in insufficient workpiece machining precision and poor surface quality consistency, affecting product quality. The sealing structure design of the processing area is simple, and if gas protection is attempted, gas leakage is easy to occur, reducing the protection effect. At the same time, the dust generated by milling is easy to diffuse, not only polluting the working environment, but also needing additional investment for cleaning, and the integrated design of waste collection and treatment is lacking, and the operation is complicated.

[0005] When replacing materials or adjusting processing parameters, the traditional device often needs to be stopped for operation, resulting in production interruption and inability to realize non-stop cyclic operation, further restricting the improvement of production efficiency. Therefore, a multi-device on-line automatic gas protection light metal and its alloy milling device is urgently needed to improve the production efficiency and quality of hydrogen storage materials.
