The bolts between the screen box and the steel frame are clamped, and the bolt holes are designed to be assembled with a large gap, so the bolts are only subjected to tensile force and are not subjected to shearing force. That is, it only bears the pre-tightening force, the pulsating inertia pulling force and the frictional shearing force. In addition to the clamping bolts on the joint surface, there must be a reaming hole positioning bolt that directly bears the shearing force.
For fasteners, there should be sufficient yield strength, moderate stiffness and high toughness for higher strength bolt materials, usually made of medium carbon steel No. 35, and quenched and tempered into a soxite metallurgical structure. Therefore, the comprehensive mechanical properties such as strength, plasticity and impact toughness are obtained. The clamping force of the coupled part is achieved by the elastic deformation of the bolt and the connected part. The rigidity of the bolt should be moderate, not too large, the bolt is not as hard as possible, and the bolt must meet the clamping force. Higher toughness and high toughness metal under the action of variable load, the ability to absorb energy is increased due to intragranular friction, which can quickly alleviate and eliminate vibration, moderate or low stiffness and high toughness. It can improve the anti-fatigue performance of bolts, so the selection of bolts should be based on the state and nature of the force, rather than simply the performance level of the bolts. The higher the grade, the better, the higher the strength, stiffness and hardness. It will reduce the plasticity, toughness and weaken the fatigue resistance.
Clear & Ultra Clear Tempered Glass, color tinted Tempered Glass , tempered Back Painted Glass, silk &Digital Printed Glass mostly be used for furniture, table top, barn door, canibet door, shelf, whiteboard, cutting board, usually in relatively small size, but different design, shape, thickness, color, make to order; Adding glass to the top of your furniture provides protection from daily use. A glass top will keep the original look of your furniture and reflects the natural light to enhance the beauty of your original look of your furniture and reflects the natural light to enhance the beauty of your furnishings. Glass tops are sanitary and easy to clean. There is no better way to protect your furniture from wear and elements like a glass top and so on. Dining tables, patio furniture, desk tops and more – is both stylish and functional. The glass furniture is totally environment-oriented. The glass furniture is best option for those people who faces the allergic diseases. Transparency Of The Glass: The glass furniture will make your room look more easy and light. The glass furniture is almost invisible as we compare it to wood furniture such as wood drawer & massive tables.
