Technical background
Due to the development of new energy vehicles, die-casting products tend to be very large die-casting parts, such as new energy vehicle chassis, battery cases and heavy trucks, communication die-casting parts and other products require 6000T or larger die-casting machines.
For the above large die-casting parts, we have successfully developed the relevant technology of large die-casting clear channel, feed outlet and large handle discharge; The key technologies of plasma continuous cutting and robot automatic edge finding are successfully solved. This technology is suitable for all the feed port removal processes of very large die casting machines, almost regardless of the shape and size of the pressured castings, and can be cost-effective and efficient.
Equipment principle
Plasma is a gas heated to extremely high temperatures and highly ionized, which transfers arc power to the workpiece, and the high heat makes the workpiece melt and be blown off, forming the working state of plasma arc cutting.
Product advantage
If the traditional oil press to gate process is used, the price of the oil press and the cutting die designed according to different products are very high, and the removed runner and handle need to be eliminated with more complex equipment. If the deformation of large die-casting parts is large, it is more difficult to manufacture and trim the cutting die. The traditional sawing machine cutting the feed port will also encounter the problem that the sawing track is complex and irregular and cannot be completed. Our plasma cutting technology completely avoids the problems in the above methods. Compared with laser cutting, laser cutting costs are high, and can only cut aluminum below 10MM. And lasers are expensive. This equipment has been in the domestic, international first-class electric vehicle enterprises, mature application of a number of equipment.
