Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting and crushing, and in particular to a metal cutting and crushing device and method. Background Art

[0002] Metal cutting is a material removal and forming method in the metal forming process, that is, using a tool to remove excess metal from the workpiece to be processed to obtain parts with geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. During the metal cutting process, long strips and lumps of chips are generated, which have always been the most difficult chips to handle. Because of their large volume, the stacking area occupies a large area, so these chips need to be crushed.

[0003] Currently, metal chips are temporarily stored in bins after being crushed. Although the metal chips can be converted into smaller particles or fragments after being crushed, they still form a porous and fluffy state when stacked. This limits the amount of metal chips that can be stored in the bins, requiring regular cleaning of the bins and increasing the transportation cost of the metal chips.
