Silicon Nitride Ceramic:
Deep drawing, also called drawing or rolling, Silicon Nitride Ceramic Yarn Wheel Guide Roller Caster is a method of punching and processing that uses a die to make a flat blank after punching into an open hollow part. The drawing process can be used to make cylindrical, stepped, tapered, spherical, box-shaped and other irregularly shaped thin-walled parts. If matched with other stamping forming processes, parts with extremely complex shapes can also be manufactured. In stamping production, there are many types of deep-drawn parts. Due to the different geometric characteristics, the location of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state Silicon Nitride Ceramic Yarn Wheel Guide Roller Caster and distribution law of each part of the blank have considerable, even essential differences. Therefore, the method of determining the process parameters, the number of processes and the sequence, and the principles and methods of mold design are different. According to the characteristics of deformation mechanics, various deep-drawn parts can be divided into four types: straight wall revolution (cylindrical parts), straight wall non-revolution (box-shaped body), curved revolution (curved part) and curved non-revolution. Types of. Stretching is to apply a tensile force to the sheet by the stretch die, which causes the sheet to produce uneven tensile stress and tensile strain, and then the mating surface of the sheet and the stretch die Silicon Nitride Ceramic Yarn Wheel Guide Roller Caster gradually expands until it is fully fitted with the stretch model surface. The applicable object of stretch is to manufacture hyperbolic skins with certain plasticity, large surface area, gentle and smooth curvature changes, and high quality requirements (accurate shape, smooth streamline, stable quality). Because of the relatively simple process equipment and equipment used in the stretch forming, the cost is low and the flexibility is large; but the material utilization rate and productivity are low.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
