Plasma cutting solution for integrated die casting burrs

New energy automobile factories have launched the innovative application of integrated die-casting technology in auto parts, which has made global auto brands follow suit. The general trend of integrated die-casting has promoted the popularization and promotion of large-scale integrated automobile structural parts. Using super-large die-casting island and integrated die-casting process to produce new energy vehicle chassis parts, battery shells, heavy-duty truck parts, communication parts and other products, simplifying complexity, not only improving production efficiency, but also reducing production costs.

Large-scale die-casting parts produced by 6000T or larger tonnage die-casting islands bring new challenges to the industry when removing shanks and excess scrap. Using the traditional hydraulic equipment to remove the gate process, the hydraulic equipment and the matching trimming die are expensive, and the removed runner and material handle need to be eliminated with complex equipment. Due to the large deformation of large die castings, it is difficult to manufacture and trim the trimming die. In addition, the traditional sawing machine also encounters complex and irregular sawing trajectories when cutting the feed opening, making it difficult to achieve efficient and economical sawing.

Large Die Casting Plasma Cutting System

Aiming at the problem of removing scraps such as shanks from large die castings, the plasma cutting system for super large die castings adopts plasma cutting technology, which can well solve the problems in the above methods. Compared with laser cutting, the latter cutting cost is high, and it can only cut aluminum under 10mm. "

According to reports, the ultra-large die-casting plasma cutting system has overcome the key technology of continuous plasma cutting, and can easily remove large-scale die-casting runners, feed inlets and oversized material handles. It is suitable for the feed opening removal process of all large die castings, and is hardly affected by the shape and size of the die castings, and can complete the cutting of the feed opening at low cost and high efficiency.

Robots and cutting tips for plasma cutting systems for large die castings

It is understood that plasma is a gas heated to a very high temperature and highly ionized, which transfers the arc power to the workpiece. The high heat melts the workpiece and is blown off by the gas, forming a working state of plasma arc cutting. After the compressed air enters the cutting torch, it is distributed into two paths by the gas chamber, that is, the plasma gas and the auxiliary gas are formed. The plasma gas arc melts the metal, and the assist gas cools the various parts of the torch and blows the molten metal off.

The plasma cutting system for super-large die-casting parts adopts plasma cutting technology, which is cost-effective and can complete the cutting of castings with complex shapes and various wall thicknesses. The plasma cutting system has strong versatility and high flexibility, and various castings with complex shapes can be processed on the same equipment; in order to reduce the amount of deformation, the unused fixture platform can be replaced. For large die castings with a gate runner thickness of 6mm, the cutting speed of the plasma cutting system can reach 30mm/s.
