Choosing of Cnsuperpower Black Diamond Log Splitter:
First, the material of the cone must be selected. In previous studies, some aspects of material selection were considered: segmentation conditions; the nature and structure of the divided wood and its number; machine structure; tapered structure; material prices.
The most important factor to consider when choosing a material is hardness and ductility, especially in high-load processes. In addition, wood fibers can contain natural acids, age to the machine. Four types of material steel were selected for conical production: ordinary carbon steel / structural steel, alloy special steel, martensitic stainless steel and high speed tool steel. These steels have certain limits, performance, structure, price and use. In this case, the surface quality of the processed wood is not important.
Steel X39Cr13 and HS10-4-3-10 have better wear resistance than steel E335 and 16MnCr5, and are therefore more suitable in this case. Additional experiments were conducted on the basis of the different total costs of the selected materials. In the experiment, the tooth shape and the tool surface were studied.
The selected materials and dental specimens are shown in Table 2. The tooth sample is pressed into the rotating wood on the machine. Cutting conditions are as follows: spindle speed n = 350 r / min, cutting depth p = 2 mm; cutting time t c = 1 min. The tooth behavior during the rotation of the cone is simulated by experimental conditions. On the teeth, wearing and acting.
The force components and their interactions are analyzed in detail. Based on the analysis of the design of the cone on the teeth, X39Cr13 steel and HS10-4-3-10 steel most suitable for cone production.
Slitting is often used for wet wood cutting, so the material for tapered production is X39Cr13 steel. It is a martensitic stainless steel that is resistant to the weak acids contained in wood. Another advantage of this material is that the hardness and wear resistance lead to the retention of the core of the product. Disadvantages may be higher procurement costs, but for the total cost of the processing cone and its tool life, it is not the main criterion for selection.
