Problems Needing Attention When Using The Drive Screw
The transmission screw has the characteristics of good transmission performance, high precision, and convenient processing and manufacturing, so it is widely used in ordinary horizontal lathes. The parts of the transmission screw are generally slender, and its length L and diameter d have a large aspect ratio, about 20 to 50, which belongs to the slender shaft. Its rigidity is relatively poor, and its structure and shape are relatively complex. The threads of the transmission screw are basically trapezoidal threads, and it has high quality requirements. In addition, the structure of the transmission screw is also of the type of steps, grooves, keyways, etc., so it is easy to bend, twist and deform, and "knife" in the process of processing.

Electric Screw Press Is A New Type Of Energy-saving And Environmentally Friendly Press
The electric screw press has the characteristics of simple structure, small size, short transmission chain, convenient operation, safe operation, and small maintenance workload. The strike energy of the electric screw press can be accurately set, the impact force is displayed, and the energy and impact force can be adjusted according to the molding accuracy. To reduce the mechanical stress and thermal contact time of the mold and prolong the life of the mold. Electric screw presses have two transmission forms: one is an electric screw press transmitted by a first-order gear, with specifications of 0.4MN~ 80MN, and the other is a direct-drive electric screw press with specifications of 0.16MN~ 16MN. The press body has good rigidity, high guiding accuracy of the slider, and strong anti-eccentric load ability. It can be used for multi-station die forging. It is a new type of energy-saving and environmentally friendly press.
Do You Know What Requirements Need To Be Met For The Material Of The Screw?
It can be seen from the extrusion process that the screw works under high temperature, certain corrosion, strong wear and high torque. Therefore, the screw must meet the following conditions
Ball Screws Are Commonly Known As Screws, Do You Know These Characteristics?
The ball screw has basically replaced the trapezoidal screw, commonly known as the screw. What are its characteristics?
