What factors will affect the shearing quality of the shearing machine
Author : admin Time : 2021-05-17 AllPageView : 282
It is a very responsible physical process from the deformation of the steel plate to the completion of the shearing, which depends on the interaction of the forces. In the detailed analysis of the shearing process of the shearing machine, a problem arises: the size of the unit shear resistance will directly affect the shearing quality. So what issues will affect the unit shear resistance?
1. Metal properties: When steel plates are produced, materials with different strengths will be produced according to different element ratios. The higher the strength of the material, the greater its shear resistance and the lower its plasticity. It is very inconvenient to cut, the quality is also very bad, and it will also cause damage to the cutting edge. So pay more attention to cutting materials.
2. Shearing temperature: The steel plate will be heated at high temperature during the shearing process. The function is to facilitate the steel plate to be better sheared. At this time, if the temperature is higher, the unit shear resistance will be smaller, and the shear blade will go deep into the section. The higher the temperature, the higher or lower the temperature plays a very important role.
3. Deformation speed: The early stage of the steel plate shearing process is the press-in deformation stage. At this time, it depends on the steel plate deformation speed and the shearing blade cutting speed. At this time, it is not only related to the material material but also related to the temperature of the shearing machine. . Of course, if it is cold cut, this effect will not exist.
4. Lateral clearance of shear blade: With the continuous movement of the steel plate, the steel plate will be rotated and displaced. At this time, in order to ensure the cutting quality, it is necessary to apply pressure to the steel plate on both sides of the shear blade. The distance between the two sides directly affects the force of the steel plate. If the distance is too large or too small, the force of the steel plate will be unbalanced and the rotation displacement will change, which will result in a great reduction in the quality of shearing.
5. Shearing blade radius: Everyone knows that under the same force, the larger the area, the smaller the unit force will be. At this time, if the shearing blade radius is larger, the reaction force generated by the steel plate will be dispersed, resulting in a greater unit shear resistance. Therefore, the larger the blunt radius of the knife, the less "fast" the knife will be.
