Description

Technical Field

[0001] This invention relates to the field of casting technology, and more specifically to a trimming device for non-ferrous metal die castings. Background Technology

[0002] Die casting is a common metal manufacturing process used to produce high-precision, high-strength metal parts. During the die casting process, gates, flash, and other excess material are often formed. This excess material needs to be removed to ensure the smoothness and geometric accuracy of the part's surface. Simultaneously, die-cast parts typically have some surface roughness or porosity. Surface treatments such as grinding and polishing can improve the appearance quality and enhance corrosion resistance. For parts requiring precise dimensions or special shapes, such as holes and slots, machining may be necessary after die casting to meet design requirements. These processes necessitate the use of die-casting trimming devices.

[0003] Insufficiency of existing technology: Die-cast parts come in different shapes, specifications, and sizes after forming. Existing processing equipment has certain limitations when clamping die-cast parts of different sizes, and cannot meet the trimming requirements of castings of different specifications. When trimming hardware die-cast parts, existing automated trimming devices mostly discharge the debris generated during trimming to the bottom of the machine tool after simple treatment, and then clean it. This is not only troublesome to clean, but also increases labor costs. Since many die-cast parts cannot be completely fitted to the base when placed on top of the fixture, some debris will enter the bottom fixture of the workpiece, which will affect the fixture.
