When the extruder is extruding alloy materials, especially zinc-tin alloy materials, due to the uneven interface, the metal material turn-up occurs when the rod is connected to the rod. Turn-up has a certain impact on the subsequent processing, which is serious It will affect the final result of the product. So how to solve this problem?
To
First of all, it is necessary to configure a cutting machine for the extruder to cut each head of the cast bar. The advantage of this is that the interface is in a horizontal line and it is not easy to turn up; secondly, it is required to design the die temperature At the time, set it to a higher temperature than the die for squeezing solder.
To
In addition, the extruder can also control the working pressure through the mold, the wire outlet method and the wire diameter, and adjust the appropriate wire speed to solve the problem of uneven interface. Because the extruder has redesigned the extrusion wheel, not only can the structure be quickly replaced, the assembly and replacement of the extrusion wheel is convenient, and the maintenance time is shortened. The movement gap between the extrusion wheel and the mold is precisely adjusted to improve the service life of the mold.
To
Not only that, the extruder is usually equipped with a molding plate with various shapes of holes at the end of the screw sleeve. It can not only mold the extruded material into the required shape; it can also be used as a baffle to increase the extrusion The pressure in the mechanical maturation zone. However, it is important to know that determining the geometry of the die hole has a very important effect on the shape and quality of the extruded product.
To
The molding of the extruded material after molding by the extruder must be equipped with a cutting mechanism. The cutting mechanism needs to be able to evenly cut the molded extruded material into a product with a neat surface according to the specified length. Under normal circumstances, the length of the cut material depends on the cutter speed; the faster the cutter speed, the shorter the cut material length. The neatness of the cut material depends to a large extent on the gap distance between the cutter and the die.
