Swivel lever snap manufacturing process and type
What is the production process of the swivel lever snap? What types of swivel lever snaps can be divided into? Let me talk about the craft and type of rotating rod snaps. I hope to help everyone.
swivel lever snap making process
The production method of the swivel lever snap includes a cover plate and a hot pressing process production method in the middle portion. The production method of the cover plate is as follows: after the steel plate is formed into a blank by the punching machine, the blank is heated, and the shape of the cover plate is punched out by the punching machine, the rotating rod is buckled and the workpiece is cooled, and then punched into the punching hole by the punching punching machine, and then The workpiece is placed on the boring machine, and a protrusion is formed on each of the outer sides of the opening hole to form.
The production method of the middle part is as follows: after the steel plate passes through the blank of the punching machine, the elongated hole is punched out at the position of the longitudinally installed bolt of the cross wire, the workpiece is heated, and the shape of the middle part is punched according to the mold; after cooling, the workpiece is placed on the inclined table. , fine punching and forming each hole.
The hot stamping process increases the toughness of the swivel lever snap and is not easy to be deformed. After the hot stamping of the swivel lever snap, the arc of the R arc is increased, so that the area of the joint surface of the bayonet is increased, thereby increasing the contact area. The large friction force makes the swivel lever snap safer and more reliable.
The rotary swivel lever is a standard part that is produced in batches by a special swivel lever snap factory. Factors that often need to be considered in design selection are life, load, accuracy, clearance (radial and axial), ultimate speed, friction torque, centering performance, preload and stiffness, vibration and noise.
The type of swivel lever snap
1. According to the shape of the rolling element, it can be divided into a ball swivel lever snap, a roller buckle and a needle roller buckle.
2. according to the bearing direction can be divided into centripetal swivel lever snap (bearing radial force and small axial force), thrust swivel lever snap (can only bear axial force) and centripetal thrust swivel lever snap ( Can withstand both radial and axial forces).
3. according to working conditions can be divided into ordinary swivel lever snap, high-speed swivel lever snap, high-temperature swivel lever snap, low-temperature swivel lever snap, vacuum swivel lever snap, anti-magnetic swivel lever snap, corrosion-resistant swivel lever snap , precision micro-swivel lever snaps and extra large fasteners. China has divided the various types of rotary rotating rods into five precision levels: B, C, D, E, and G. B is the highest precision level, and G is the ordinary precision level. The application is most common.
The above is about the production process and type introduction of the swivel lever snap. I hope everyone can understand the manufacturing process and types of the swivel lever snap, which will help everyone.
