Spiral blade cold rolling process to amorphous strip or strip as embryo, in the blade cold rolling machine continuous hot rolling spiral blade. Its mechanism is the embryo in the angle suffered a pair of hot-rolled strip produced by the deformation of the cold-rolled gap of the uneven working pressure, causing the embryo vertical widening uneven, tensile strength from the large to the inner edge slowly reduce.

If the inner edge does not suffer working pressure, the inner edge will become thicker and shorter. The result of the deformation melting is to get ring parts that last for many turns. Depending on the adjustment of the relative position of the hot rolled strip and embryo in different interior spaces, it is possible to obtain spiral blades of different sizes and characteristics. Because this kind of production equipment has good operational flexibility, it can produce and process different kinds of blades without upgrading other moulds, and it only needs to adjust the relative indoor space association between hot-rolled strip and embryo in the middle accordingly. Therefore, carry out multi kinds of production and manufacture, mass production and bulk production and manufacture. Compared with other spiral blade production and manufacturing method, this method has the advantages of energy saving, raw material, low labor efficiency, optimization, convenience, automation technology, etc.

About the spiral blade shear mode:

1. spiral blade plate through the upper and lower shears under the efficacy of shear, and then cause the separation out of deformation, spiral blade in shear time will not be able to fixed immobile, in the beginning of the shear, the upper shear head pressed into the plate, causing a pair of shear stress and the corresponding torque, drive the shear plate rotation.

2. In the whole process of rotation, it is blocked by the side of the scissors and in the other side of the shear caused a pair of lateral push force and the corresponding torque, the orientation of the blocked blade rotation. When the spiral blade starts to shear, the direction of the sheet is raised along with the pressed-in depth, and the torque is also raised. At this point the sheared metal sheet terminates the rotation until it is sheared.

The key raw material for making spiral blade is stainless steel plate and other metal materials, and the strength is relatively large but nowadays is not suitable for general shearing way, need special props to carry out.
