Socket Sets Suppliers

 The advantage of the thread formed by the rolling process is that the plastic metal fiber streamline of the thread part is not cut, so the strength of the bolt is increased, the precision is high, and the quality is uniform. The analysis of functional requirements can be performed by using quality function deployment (also known as house of quality) technology, which is not introduced here.

The high potential can make the concentration gradient on the surface of the permeable layer large, which is conducive to diffusion and increases the permeation rate. While extruding the cylindrical screw blank, the screw blank is rotated, and finally the tooth shape on the rolling mold is transferred to On the screw blank, the thread is formed. 8. Molybdenum disulfide is the most commonly used lubricant. You must know the relationship between functional requirements and technical requirements.8, 8. The coarse thread type is not displayed in the bolt mark.

The following is the possible range of friction coefficient when different lubricating materials are matched with different thread surface treatments. It uses a rolling (rolling board) mold with the same pitch and tooth profile as the thread to be processed. If the working temperature is exceeded, the lubricating effect will be lost.

According to the shape of the head: there are hexagonal head, round head, square head, countersunk head and so on. IX. If it is too much, the efficiency is low, and the surface of the thread is prone to separation or random buckling. General grease can play a role in lubrication and has a certain anti-corrosion effect, but if the ambient temperature is higher than 120 degrees Celsius, the grease will play a role. Different surface treatment methods have different anti-corrosion grades,

and the Socket Sets Suppliers of anti-corrosion coatings are also different, and the use temperatures of different coatings are also different. Fourth, the design materials are ready, the process sequence is very important. A type of fastener consisting of a head and a screw (cylinder with external thread), which needs to be matched with a nut to fasten and connect two parts with through holes.
