Reasons why the spiral blade cannot penetrate the central axis

During the completion of the conveying operation of the spiral blade, the blade sometimes cannot penetrate into the central axis, and it cannot be used if it cannot be penetrated. Therefore, I will give you some reasons for the analysis. Below, I will introduce the reasons why the spiral blade cannot penetrate. :
First, buyers are reluctant to buy small eyed spiral blades, because the inner diameter of the blade and the outer diameter of the shaft are appropriate, maybe the smaller one makes it difficult to insert the blade, or it is difficult to penetrate, this blade is not easy to get.
Second, when the customer encounters, especially when the blade penetrates halfway, the inner diameter of the blade is smaller than the outer diameter of the shaft and cannot be strung inward. Because the blade has the nature of a spring, and it is difficult to withdraw, the worker may have been busy for a long time and did not get in or out, resulting in cutting and scratching, which wastes time and leaves the blade.
Reasons for this situation:
The main reason is that when the blade passes through the cold rolling mill of the blade, it is caused by the bounce amount of the blade itself and the production operation is not approved in time. Generally speaking, as long as this situation is present, the manufacturer can return the product.
Fourth, the basis of blade selection:
1. According to the material function that the auger blade should have when using, including mechanical function, physical function and chemical function.
2. For the blade, the mechanical function is the goal. The parameters that characterize the mechanical function are mainly the strength limit σb, the elastic limit σe, the yield strength σs or σ0.2, the elongation δ, the section reduction rate ψ, the impact toughness ak, and the hardness. HRC or HBS.
The spiral blade is mainly used for conveying materials with high viscosity and compressibility. It has the functions of stirring and mixing the materials. If it does not penetrate the central axis, it will affect the use of the equipment and the equipment with poor quality performance. No one bought it, so manufacturers should pay more attention.
