Methods for Preventing Carding of Small Specification Rolling Stock Shearing
In recent years, the production of small-spec rolling stock shearing in various factories across the country has been increasing, but the occurrence of carding has also become a focus of concern for production operators. Carding is a common problem in rolling stock shearing processes and is caused by the premature closure of the upper and lower chassis and the excessive pressure of the shearing machine. Today, we will take a look at the methods for preventing carding of small-spec rolling stock shearings.
1. Smoothing the shearing edge
This method is generally used before the shearing process. Smoothing the shearing edge is an effective way to prevent carding. It not only ensures that the edges of therolling stock are smooth and flat, but also prevents carding caused by too much residual strip on the edges of the sheared material.
2. Adjust the gap between the upper and lower chassis
This method is often used in the process of rolling stock shearing. The thickness of the sheared material should be measured in advance and the gap between the upper and lower chassis should be adjusted according to the size of the material. The adjustment of the gap can properly control the pressure of the shearing machine and prevent the premature closure of the upper and lower chassis, thus avoiding the occurrence of carding.
3. Adjust the speed of the shearing machine
The speed of the shearing machine also affects whether or not carding occurs. Generally speaking, when the shearing speed is fast, the pressure generated by the shearing machine is large, which is easy to cause carding. Therefore, adjusting the speed of the shearing machine to an appropriate value in the shearing process can effectively prevent carding.
In summary, carding in the production of small-spec rolling stock shearing is a common phenomenon that needs to be avoided. Here we discuss three methods to prevent carding of small-spec rolling stock shearing: smoothing the shearing edge, adjusting the gap between the upper and lower chassis, and adjusting the speed of the shearing machine. Implementing these methods can effectively prevent carding in rolling stock shearing and ensure the quality of sheared products.
