Generally, the high-quality metal briquetting machine compresses the iron chips from three directions. During the whole process of pressing and shearing, the iron chips are deformed greatly, the density of the iron briquettes is large, and the volume is small. After that, the four hydraulic cylinders drive the turnover plate to rotate around the hinge axis. The iron chips can be turned over and taken out from the rectangular loading trough, with fast feed speed and high work efficiency. The deformation of iron filings from indentation to shear forming is a very physical process, which depends on the interaction of forces. During the shearing process of metal briquetting machine, the shearing quality will be directly affected.
1. Related to the metal properties of iron filings:
When iron filings are produced, resources with different strengths will be produced according to different element shares. The higher the strength of the scrap iron raw material, the greater the shear resistance and the lower the plasticity. The metal briquetting machine is very inconvenient to cut, and the quality is also very poor, which will also damage the cutting edge. Therefore, you should pay more attention to cutting resources.
2. It has something to do with the temperature of iron chips sheared by the metal briquetting machine: the iron chips will be heated at high temperature during the cutting process of the briquetting machine, so that the iron chips can be cut better. At this time, it is assumed that the higher the temperature, the smaller the unit shear resistance, and the greater the depth of the cutting edge into the section. The concave and convex of the temperature plays a very important role.
3. The deformation speed of iron filings sheared by metal briquetting machine also affects the quality:
The early stage of the iron chip shearing process is the pressing deformation stage, which depends on the iron chip deformation speed and the cutting speed of the cutting edge. At this time, it is not only related to the raw material but also related to the temperature of the briquetting machine.
4. It is related to the lateral clearance of the cutting edge of the metal briquetting machine: with the continuous movement of the iron filings, the iron filings will have rolling displacement. At this time, in order to ensure the cutting quality of the briquetting machine, the two ends of the cutting edge need to apply pressure to the iron filings. The spacing between the two ends directly affects the stress condition of the iron filings. If the spacing is too large or too small, the force on the iron filings will be uneven, resulting in the change of rolling displacement, and then the shear quality will be greatly reduced.
5. Let's look at the influence of the radius and quality of the cutting edge of the metal briquetting machine: we all know that under the same force, the larger the area, the smaller the unit force. At this time, it is assumed that the larger the radius of the cutting edge, the weaker the reaction force generated by the iron filings, and then the greater the unit shear resistance. Therefore, the greater the blunt radius of the knife, the less "fast" the knife is.
The cutting process of iron filings in metal briquetting machine is a very complex physical process. If many factors are not paid attention to, they will directly affect the cutting quality and reduce the work efficiency. In addition to the five common elements listed above, other elements such as the dash shape of the pressing plate, the friction coefficient and the cutting edge of the iron cutting edge will have an impact, as long as they have a relatively small effect.
