Formation of spiral blades

Spiral blades play an important role in conveying high-viscosity and compressible materials. It has strong corrosion resistance and abrasion resistance. It has a long service life and a variety of processing methods. Let us introduce the blades to everyone. Formation method:
1.Single piece manual hot pressing method
1. It is a traditional forming method, currently used by some small and medium-sized enterprises. This method is to heat the blanks according to the single-sheet development diagram to about 700 ° C, and then use a manual hammer to shape the single-sheet thermoformed tire.
2. The characteristics of this method:
① The forming process is simple and suitable for small and medium-sized enterprises.
② Poor production conditions, high labor intensity and low production efficiency.
③ The forming quality is unstable and the welding assembly error is large.
④Suitable for sheet metal forming.
Second, the hot press forming method
1. It is to heat the good blank under the single-sheet expanded view to about 700 ° C, and then put it into a forming tire to be hot-pressed on a press. The mounting surface of this shaped tire is perpendicular to the direction of the guide post.
2. Characteristics of forming method:
① Special hot-pressed tires need to be processed, which is suitable for mass production.
② High production efficiency, but poor production conditions and high labor intensity.
③ The molding quality is stable, but the appearance quality of the molding is poor.
④Suitable for forming blanks with spiral blade thickness.
The common processing methods of spiral blades are hot-pressing of tires and manual hot-pressing of single pieces. Due to technical obstacles, these two methods are not ideal. With the continuous development of science and technology, there will be more high-tech Technology has been worked out.
