If you've heard of tire shredder blades, you must know that they are used to shred all kinds of waste, including waste wood and old sofas. Do you know how much energy it produces? Speaking it will definitely surprise you.
The tire recycling machine blade can directly turn the entire abandoned sofa into pieces in a short time. This is not the worst. The twin-shaft tire shredder is made of a tire recycling machine blade, shattering the steel and metal casing of the scrap car and aluminum alloy less than 5 mm thick. It shows the strength of the tire recycling machine blade. For a simple moving example, the shredder blade makes you feel at your fingertips. The strength of steel is generally 1000pa, which is the unit of strength. It was converted into a mechanical device that applied a force of 10,000 kg in the little finger area. To what extent, a force of 10 tons acts on the little finger. It is conceivable that the force acting on the little finger is similar, and it is not difficult to understand the force of the shredder blade.
If someone doesn't understand it in the future, you can use physics to help him solve the problem.
So what are the three main points of the tire shredder blade crusher?
First: tools are fragile
Under the action of mechanical and thermal stress, brittle damage of cemented carbide and ceramic tools often occurs in the following forms.
Second: tool plastic is damaged
During the cutting process, due to the effect of high temperature and high pressure, the contact layer between the front and back sides and the chip and the workpiece may flow plastically, resulting in a decrease in cutting ability. This is the tool's plastic damage. The plastic damage of a tool is directly related to the hardness ratio of the tool material to the workpiece material. The higher the hardness ratio, the smaller the plastic damage. Cemented carbide and ceramic tools have high hardness at high temperatures and are not prone to appear. This phenomenon often occurs in high-speed steel cutting machines due to poor heat resistance.
Third, the brittle damage durability of the tool
Tool breakage is a typical random phenomenon and is different from normal wear. Therefore, the law can be studied using probability theory and mathematical statistics. The so-called chipping durability refers to the number of times the cutting edge of the tool is impacted when the blade is broken. The cutting edge of the tool cannot continue cutting until the side grinding standard is reached.
