Manufacturing Difficulty
This screw flight for screw conveyor is a spirochete with conical inner and outer diameters. Of all the spiral flighting, this is the most difficult to produce.
To make a spiral screw flight, there are four elements. Outer diameter, inner diameter, pitch and sheet plate thickness. These four factors are all out of the usual range.
Outer diameter and inside diameter are all changing by a cone shape. They are all changed from big size to a small size. The largest OD diameter is 1.2 meters, to the smallest 430mm. It is difficult to guarantee the concentric degree of the spiral by all this changing.
The thickness of the plate is 50 mm. It is a thicker steel plate. Steel plates are cold rolled. Therefore it is extremely difficult to make a spiral for this thick plate. If there is even a mistake in the production process. There is no way to re-produce.
This order of screw flight of scew conveyor is a trial order. There is only one quantity. So, it is necessary to ensure success in production in once time.
Solve problems for production
In view of the above factors. Our skilled workers need to make a precise calculation. Rely on their cognition of material properties. Control the corresponding changes in each step during the screw flight production process. Like a exquisite carving work in a completely manual state.
This time the spiral flight blade is welded by three parts. In order to ensure the unity of the rotation center of the spirochete. Our esteem engineers use the static balance method to find the right center and make our own welding die to ensure the balance and concentricity of products. Finally the production and one-time success of the screw flight were realized.
